At-The-Ready Consultant Services: A Streamlined Approach to Starting Your Project

If your community was awarded a grant through the Vermont Agency of Transportation (VTrans) Municipal Assistance Bureau (MAB), you can take advantage of a streamlined approach to procuring your project consultant through the At-The-Ready (ATR) process. With this choice, municipalities have an alternative option to the standard RFQ/RFP process; an option that can speed up your proposed project schedule using prequalified and reputable experts in their field with success in delivering projects in accordance with VTrans MAB standards. VTrans maintains ATR consultants from a qualified roster, ready for qualifications-based-selection (QBS) when a project arises.

This accelerated procurement method can be applied to three categories of work:

  1. Design (including Scoping)
  2. Municipal Project Management
  3. Construction Inspection

If the ATR process is something your community would like to consider, VTrans has set up a simple Guide and Flowchart that can be followed and coordinated with your VTrans Project Supervisor. Begin by defining a selection committee (minimum of two members); along with the Municipal Representative in Responsible Charge (typical members could include the Municipal Project Manager, Public Works Engineer, Road Foreman or other municipal representatives). The committee then reviews a minimum of three consultant qualifications packages and selects the firm that best meets the needs of the municipality for the particular project. Once the committee chooses a firm, they can work through the cost proposal process with the VTrans Project Supervisor and the consultant.

For a municipality, the ATR process is beneficial for more than just accelerating the procurement of consultant services. Utilizing ATR also ensures you will be selecting from qualified firms that are experts in completing MAB funded projects. Instead of preparing a laborious Request for Qualifications package and then reviewing multiple submissions, the QBS selection is made easier, giving the option of only a minimum of three to pick from, while maintaining full state and federal grant/funding eligibility.

Hoyle, Tanner has had a working relationship with the VTrans MAB group for over 20 years and has been an ATR Consultant under the Design Category since the program began in 2017. We are a prequalified Design Consultant and are At-the-Ready whenever a municipality needs.

If you have any questions about the ATR process, contact Jon Olin, PE, our Vice President and Regional Business Manager of our Vermont office.

What you May not Have Considered about Solar Energy in New England

Hoyle, Tanner is currently providing professional engineering design services for the development of solar energy in New England. We are working for several solar companies as the solar industry has not only taken off in the flatlands of our Midwest United States, but solar energy development is also happening in our New England backyards.

There are many reasons why this industry has recently become so popular. Solar energy has become a viable option because of the sun’s power – but also because of its cost. As the technology of solar energy has become more efficient, the option for purchasing solar power has become a reality to an average energy user.

In order to consider solar options, permitting and procurement need to be considered.

Permitting

Public utilities commissions and state regulators have recently developed and revised rules and regulations for the advancement of solar energy. Hoyle, Tanner has stayed up-to-date with the development of these guidelines so that we can keep our clients educated and able to make sound decisions and reliable investments — not only based on costs, but also permitting success. The probability of getting a project permitted is a major milestone in the progression of a project, and can in many cases can determine if the project ever gets started.

There are many factors that contribute to the permitting and design of a solar array. Following is a list of some major factors that can affect development:

  • What is the size and shape of the property?
  • Is the property located in a properly zoned area or can it be rezoned?
  • Are the soils adequate to develop for this use? Are there significant wetlands? Are they well drained soils?
  • Is the topography adequate for solar development? Is the orientation of the property favorable for solar development?
  • Are there abutting structures on neighboring property that would prevent sunlight from reaching the site?
  • Is there adequate access to the property?
  • Is there access to an existing power source to transmit the power?
  • Are there natural resource protection areas within the site (vernal pools, deer wintering areas, or historic preservation areas)?
  • Does the developer have adequate title to the property?

Hoyle, Tanner has developed several solar array sites being cognizant of all the factors pertaining to a successfully designed and permitted project, while keeping versed of the regulatory processes. With our experience, we can save the client time and money while helping them realize a successful project.

Procurement

In many state governments, there is a procurement process for renewable energy projects (that are part of energy packages). These packages contain guidelines for the development of a limited amount of energy. What we are finding in some states is the need to increase the development limits as demand increases. Hoyle, Tanner is working with state agencies to make sure we are aware of these opportunities so that we may share them with our clients.

In some states there is a procurement process, raising the net metering cap, allowing arrays of up to 5MW — 5,000 KW — to sell or store excess energy. 

Raising the cap is what makes renewable energy development viable for investors, developers, and municipalities. These opportunities to create renewable energy not only lower the states’ dependence on fossil fuels to generate electricity but are also expected to create new jobs in the coming years as the number of projects increase.

Many states look to increase their renewable energy portfolio standard — the amount of renewable electricity created as opposed to that created by fossil fuels — from lows currently at 10% or less to 40% or 80% by 2030 and some even at 100% by 2050.

Helping Developers

We understand the importance of this type of development and the need for development of renewable resources. Our design experience helps the developers understand the limitations of development and of course the permitting process.

Hoyle, Tanner’s experts are here to help. If you have any solar development questions, contact Andy Sturgeon, Vice President and Regional Business Manager.

Landslides: Prevention & Repair Through Slope Stabilization

Slope failure photo with blog title

In New England, March marks the last weeks of winter and the start of spring rains and snow melt.  Paying attention to erosion control during this time of year is always on the minds of municipal public works staff, state agencies, construction companies, and even homeowners, especially those fortunate enough (or perhaps not) to have water frontage. 

A 2018 study conducted by the USDA found that precipitation is increasing in the northeast more than any other region in the United States. The frequency of consecutive wet days is generally increasing in the northeast and precipitation extremes have also become more frequent. Given these trends, it is no surprise that peak flows in rivers and streams are also increasing and occurring earlier in the year which can result in a greater risk of flooding.

While it is difficult to prevent major erosion of stream and river banks due to extreme precipitation events, damage can be mitigated by inspections of at-risk areas combined with prioritization of these areas for repair. It is important to address slope failures quickly because bank degradation can cause significant damage including loss of property and infrastructure, sedimentation of the waterbody, water quality issues and damage to critical riparian buffer areas. As civil engineers, we can provide assistance with erosion control issues that range from preventative design practices, culvert replacements and stabilization of failed embankments.

Below is a list of some stabilization practices along with before and after photos of our recent embankment stabilization projects.

One such embankment failure occurred in Lancaster, New Hampshire, when high flow conditions in the Connecticut River resulted in severe washouts along an 800 foot long embankment causing loss of land and unstable soil conditions. Hoyle, Tanner designed and permitted solutions to repair and stabilize the slope using native riparian vegetation and rip rap armament. Live willow and dogwood stakes were planted in soil between the rip rap stones.

Terms to know:

  • Live willow & dogwood stakes: Living shrub cuttings that take root quickly in bank environments – provides natural habitat and additional erosion control
  • Rip rap: Large stones used for protection and dissipation of energy from high water flows

Lancaster Embankment after Stabilization

Hoyle, Tanner also designed and permitted repairs to a steep slope in Rochester, Vermont, when intense rainfall events undermined the toe of the bank, causing the slope and roadway above to fail and slide into Brandon Brook 90 feet below.  The repair solutions included installation of a blast rock toe detail and stone facing with grubbing material along the hillside to restore the slope. The roadway was reconstructed and a mid-slope underdrain was installed to intercept groundwater seepage. Debris from the slope failure was removed from Brandon Brook and the streambed was restored.

Terms to know:

  • Stone facing with grubbings: Combination of stone and native material to promote vegetation growth
  • Blast rock toe: Large rocks placed at the toe of the re-stabilized slope to combat undermining

Improving safety and combatting damage from growing peak flows and extreme storm events is an important part of our job. Hoyle, Tanner is excited to offer solutions to slope stability issues and challenging site conditions. For more information on how we can be of assistance, please contact me.

Working on a Construction Site: A Woman’s Perspective

Construction photo with a yellow machine building a new bridge

This summer I had the pleasure of working very close to my hometown as a resident project representative (RPR) for two bridge construction projects in the Town of Gilmanton, New Hampshire. Funding from NHDOT’s Municipally-Managed State Bridge Aid Program allowed the Gilmanton to upgrade two pieces of its aging bridge infrastructure on Stage Road.

The Project

The previous bridge crossing at Nighthawk Hollow Brook was comprised of steel beams with a concrete deck. Originally built in 1930, and rehabilitated in 1960, the bridge was undersized to convey water flow, causing frequent roadway flooding by over a foot. A hydraulic analysis of the bridge revealed that to prevent future flooding, the roadway should be raised by several feet and the bridge span should increase. Less than a mile to the south is the bridge at Unnamed Brook crossing, which was also built in 1930. The supporting earth was washed away around the existing bridge because of puddling on the roadway and poor drainage. Hoyle, Tanner partnered with the Town to design both replacement structures, obtain necessary regulatory agencies’ permits, and administer the construction phase.

The design of a new 54-foot span bridge with over 3 feet of raise in the roadway profile over Nighthawk Hollow Brook was completed in late 2018. The design of the Unnamed Brook crossing was completed at the same time and included a 22-foot span bridge with drainage and roadway safety improvements. The Town’s goals for these projects were met with the design of two low-maintenance bridges with a long service life and improved water flow and drainage, while successfully addressing environmental permitting requirements. The projects were advertised together under one contract for bidding in winter 2018-19, and awarded to E.D. Swett, Inc. of Concord. Construction commenced in May 2019 with the installation of a temporary bridge at the Nighthawk Hollow Brook crossing, and a detour at the Unnamed Brook crossing in July 2019.

My Experience

As the RPR for this project, I was responsible for ensuring that the daily construction activities adhered to the contract plans and specifications. It involved effective organization, documentation, and measurement of the construction progress, but most importantly, it involved constant communication between the contractor, subcontractors, client, and engineer.

One of the first things I like to do as the RPR of a new project is establish a feeling of trust with the Contractor’s foreman, who controls the day-to-day operations of the project site. When working with someone new as a young, female engineer, I have been cautioned that people may doubt my abilities, as opposed to my male counterparts.

While I have been cautioned that people may not take me as seriously as my male counterparts, I did not feel that having to build trust or learning to communicate in a direct manner had much to do with me being a female. I know from experience that men and women communicate differently. Our choice in words, our verbal and nonverbal actions, and our responses to each other are different. Because I’m comfortable with verbal communication, I learned to alter my statements, questions, responses, and conversations in a way that was as clear as possible to each person I came in contact with.

Instead, I think it came down to being younger and not as experienced; that even a younger male engineer would have to prove his knowledge and win the trust of the construction site workers. Thankfully, with a high confidence level, and using effective communication, I was able to gain the trust of the foreman by proving my knowledge in a variety of situations. Having this trust with the foreman allowed us to rely on each other for the remainder of the project and easily work through any discrepancies.

Overall, my experience has been positive as a woman on a construction site. I feel confident in my abilities to make sure the work gets done on time, correctly, and under budget. I feel comfortable in this type of workplace communicating with people very different than myself. The men I have worked with are kind, understanding, hardworking, and like to joke around when there’s time for it.

Through the efforts of all parties involved, the two bridges were reopened to traffic in November 2019. Both projects were substantially completed and under budget with minor cleanup work and final paving scheduled for late spring 2020.

A Tribute to Our Roots

Hoyle, Tanner founders gathering around a document signing

As we begin our 47th year in business, we pay tribute to our founders who exemplified courage, resilience, commitment and innovation while building the solid foundation from which the company operates today.

Doug Hoyle was a lot of different things — a graduate of Brown University, a Korean War veteran, a licensed pilot, an avid skier, motor sport enthusiast and co-founder of a company that still bears his name. Although his list of personal accomplishments is long, throughout his career, his key interest remained the same: to be recognized as Chief Engineer. In 1973, Doug Hoyle along with John Tanner and Bill Thomas founded the engineering firm Hoyle, Tanner & Associates, Inc. and opened an office in the Ammon Terminal building at Manchester Airport. This marked the beginning of what now has become a very successful 46-year history in the civil engineering business.

Together, the original team of three built Hoyle, Tanner from the ground up; their individual beliefs, experiences, talents and business strategies complemented each other nicely.

Doug would take the lead for the company in the field of environmental engineering. Doug understood that by utilizing the availability of funding from the federally-sponsored Clean Water Act of the1960s, water quality could be significantly improved, and this was to be especially relevant to the many municipalities in New Hampshire’s Lakes Region. This work would become an important source of repeat business for the company, as well as establishing a reputation for high quality engineering in environmental services.

John Tanner also recognized the importance of a reliable source of funding for projects. His interest was in public transportation; he utilized the federally-funded Airport Development Aid Program which assisted airports by providing funds to finance capital improvements and maintenance projects. John led the way in this effort and was instrumental in building a national reputation for Hoyle, Tanner within the aviation industry. Unlike the other two founders, Bill Thomas was not an engineer but an experienced and insightful businessman who played a crucial role in business development, serving as the face of the company, and playing an instrumental role in important business decisions that affected Hoyle, Tanner’s future. Their personalities interwove together perfectly.

Doug Hoyle, a man of unwavering honesty and integrity, was a competent and traditional professional who made rational and calculated decisions. His pride was not in the name on the door but instead in his duty as Chief Engineer.

John Tanner was a gifted manager and a natural leader. John was always forward-thinking with big ideas and an ability to listen to a room full of people and distill a complex discussion to its core elements.

Bill Thomas was very personable; a natural conversationalist at ease in any social or business situation. Bill possessed the sound judgement and insights that would help to establish the firm’s culture and guide the company through future technological changes.

Together, the founders created a company culture of customer-driven quality and professionalism that is still very much in evidence at Hoyle, Tanner today. For 46 years, the company has been resilient and adaptive, embracing challenges and taking measured risks that are in the best interest of both our clients and our employees. Engineering is a continuously evolving industry. Hoyle, Tanner’s ability to adapt, anticipate these changes and persevere is something that has been with us since we first started in 1973 and that will continue to see us through our 100th year in business.

Young Member’s Perspective of the NCSEA Structural Engineering Summit

SENH members at summit

This past November, I attended the NCSEA Structural Engineering Summit at the Disneyland Hotel and Conference Center in Anaheim, California. I was able to go because I was awarded a Young Member Scholarship, one of 15 scholarships awarded this year!

At the Summit, I met a variety of people from around the country including other Young Members, senior mentors, vendors for different products and software (including a woman who went to Oyster River High School in Durham, NH and whose parents live right here in Newmarket, NH like me!), and, of course, Disney characters. I connected with multiple Young Members from the Massachusetts Young Member Group (YMG), and we hope to hold a joint event so our members can expand our networks. The Young Members from around the country I met shared their YMG experiences and events that provided me with ideas to bring back to our YMG.  

There was an assortment of keynote presentations and educational topics that were well done, and I was able to walk away with something from each one, even if they weren’t directly related to what I work on every day. Presentations ranged from A Perspective on the Future of Consulting Engineers to Limitation of Liability Clauses in Engineering Contracts to Talk Nerdy to Me: Science Not Communicated is Science Not Done about presentation skills. There was an abundance of presentations to choose from during each session and even as a Young Member, there was always something for me; they even had a Young Engineer Track series on Thursday afternoon specially geared towards members 35 and younger.

Talk Nerdy to Me: Science Not Communicated is Science Not Done

During the Talk Nerdy to Me: Science Not Communicated is Science Not Done, presenter Melissa Marshall discussed how we as technical presenters could improve our presentation skills from slide presentation and content, to how presentations are given. One of the points that stuck with me was “bullets kill.” Her point was that you lose the audience’s attention by filling up slide shows with bullets because this overloads the audience with information; they usually cannot read the slide and listen to what you are saying at the same time.

She pointed out that the default PowerPoint slide hasn’t changed since the 1980s and that we all assume that bullets are what make slide effective. She suggests using a single sentence at the top of the slide (the main point you want to get across for that slide) and a visual aid. This would also help narrow down the presentation content to what is important that you want to get across to the audience.

Melissa also pointed out that it’s not only what’s on the slide, but also how you present the information. She showed a video of a statistics professor presenting the trends of life expectancy in various countries; normally people do not find statistics very riveting, but this professor sounded like a sportscaster as he showed the data changing across time and was very easy to pay attention to. Her point wasn’t that we all needed to sound like sportscasters, but to be enthusiastic about what we’re presenting and find a presentation style that really works for us as individuals. I think it’s important for all of us to know how to present to an audience effectively and Melissa’s presentation is applicable to all of our presentations.

Mentor Roundtable: Business Leaders Giving Advice & Perspective

Another session was run a little differently than the presentations: we had a mentor roundtable discussion about business development. This was held in particular for the young engineers at the Summit. We split into small groups of about eight to ten people, and then business leaders came to our tables for a ten-minute discussion. They told us a little about themselves, including how they achieved their positions and roles in their companies, and then we were able to ask them questions. This was very beneficial to see the different career paths they each took, get their advice, and caused us to think about where we want to go in our careers. Do I want to manage other people? Do I want to run my own office? Or even, do I want to own my own business? I’m still not sure exactly where my future will lead regarding these questions, but I’m glad to be thinking about the future and I think it’s important for all young people to think about where they want to be in the future.  

Takeaways

The summit allowed for plenty of social events to establish and grow relationships with new members, as well as cultivate those with members you already know. These events also allowed us to celebrate other engineers and everything we do!   

When I returned, I participated in the SENH Board Meeting on December 5th with our two Summit Delegates. We provided a lot of information to the Board that we brought back from the Summit.

I highly recommend other SENH Young Members consider applying for a scholarship to attend. The scholarship makes an amazing educational, social, and fun engineering event affordable and you’ll make lasting memories and connections. If you want to know more about my experience, please don’t hesitate to ask!

NEWEA Young Professionals Summit: What I learned about Empathy and Strength

Photo shows three young professionals, including Monika Ingalls, meeting and networking at the NEWEA Summit

On Sunday January 26, 2020, the New England Water Environment Association (NEWEA), partnered with New England Water Works Association, held a Young Professionals Summit to bring together young professionals (YPs) from the water and wastewater industries to hear from leaders in their profession and network with peers across New England. I was intrigued by this summit as I believe networking is important to furthering one’s professional career, as well as listening to those who are leaders and considering advice that they offer.

The NEWEA Young Professional Summit began with opening remarks and a large speed networking activity. This was a great way to get to know fellow YPs in the New England area. There were YPs from other consulting firms, public works departments, and graduate students. NEWEA provided several guiding questions and from there it was interesting to hear what projects other firms and municipalities were working on. One YP whom I spoke with, who was a graduate student from UNH, talked a bit about her research into removal of pharmaceuticals from water, which she was presenting in a session on Monday.

Empathetic Professionals

After four rounds of swapping partners and networking, we returned to our tables and prepared for a speech by Dr. Claire Baldwin, from CDM Smith. She spoke on the importance of empathy as engineers and as future leaders in our profession; it’s important as engineers to consider how our actions and designs will affect everyone, not just people with similar outlooks on life as us.

One example that she mentioned that I felt was especially powerful was an image of an older person with a walker attempting to climb up a steep slope next to stairs – it is clear in the image that those who are unable to use stairs were not considered during the design process. She pushed the importance of putting oneself into the shoes of all people who will be effected by a project.

Water’s Inspirational Future

Part of the day included the documentary Brave Blue World. The Water Environment Federation helped partner to create this film which provided a positive outlook on the future issues with water that the world will be faced with. It covered many different areas globally and presented entrepreneurs and scientists who are all doing their part to help solve their respective water issues. Once we viewed the documentary, we moved into a discussion about the movie and were tasked with creating panel questions for different audiences: high school students, the general public, and public officials in an area where a screening may be held. Overall, I felt this showing left me with an inkling of hope for the future – while there are problems that will become more prevalent, there will always be individuals to step up to the challenge and help the world and its inhabitants.

Strengths in Career Pathways

After this session, another speaker, Hannah Mento of Mento Mindset presented about finding what our strengths are and using these strengths to improve our creativity at work. This presentation was interesting and she helped guide us as we thought to ourselves what our strengths are, even going as far as messaging people we know to tell us what they feel our strengths are; and pushed us to consider these strengths moving forward in our careers to help improve our productivity and happiness with our jobs. It was interesting to hear the variety of strengths people discovered about themselves, whether it be communication, listening, organizational, etc. and to see whether there were strengths that we all had since we are all young engineers.

Hearing From other Young Professionals & Key Takeaways

Finally, two professionals were able to chronicle their first years as engineers and field questions from any of the YPs in the room during a panel discussion. One takeaway from this panel was the importance of remembering that it takes time to come into your own as a professional and not to feel discouraged if it is taking longer than expected.

After closing remarks, I had the opportunity to introduce myself to the president-elect of NEWEA, Jennifer Kelly Lachmayr, as well as talk with a few YPs who were new to the New England area. All in all, this was a good experience to connect with other young professionals throughout New England and to hear from speakers who wanted to help us grow more into our careers. After exploring my strengths and connecting with the professionals at the event, I am excited to participate more as a member of NEWEA and learn more from the professionals associated with the organization.

What is the PFC Debate about?

To become financially self-sustaining, airports are continually evaluating ways to generate the revenue needed to support their facility. One key program commercial service airports use to support development and maintenance is the Passenger Facilities Charge (PFC).

The PFC program was established in 1992 and instituted a fee up to $3 charged per passenger per stop, to be used by the individual airport for approved projects that include enhancing safety, security, or capacity, or increasing air carrier competition. Two decades ago, the maximum PFC was raised to $4.50 and has not been adjusted since. The PFC rate amount has been the topic of many discussions between Congress, airports, and airlines. The PFC cap increase debate is once again a topic of discussion in the current FAA reauthorization.

 

1992-2000-2020

 

Rationale in Favor of Increasing PFC Charges

Airports and industry organizations such as the American Association of Airport Executives (AAAE) and Airports Consultants Council (ACC) have been fighting for an increase in PFC charges and argue:

  • PFC is a user fee a passenger pays for using an individual airport. If you do not use the aviation system, you do not pay the price. The PFC is not an additional tax.
  • The current proposal to increase the cap on PFCs is needed to account for future inflation.
  • A simple adjustment to the PFC to account for inflation would directly support each individual airport’s infrastructure and fund the improvement projects needed.
  • As traditional revenue sources begin to decline such as parking due to rideshare companies including Uber and Lyft, airports need to identify additional revenue sources.
  • Large airports can drastically reduce their Capital Infrastructure Bonding Debt Service by funding more of the project with PFC revenue. Small communities can use the PFC to cover local share of the Airport Improvement Program (AIP) grant. Airport Council International (ACI) has a summary document that provides an example of how using PFC would significantly reduce the cost of a large scale terminal project by eliminating long-term debt payments.

Rationale in Opposition of Increasing PFC Charges

  • Airlines do not want to charge passengers additional fees.
  • The public is sensitive to airline ticket pricing and is not likely to support increased fees that will raise those fares.
  • Some airports negotiate fair and reasonable rates and charges without utilizing a PFC.

AIP Funds & Questions to Consider

Many United States airports rely on federal, state, and local funding to maintain existing capacity, accommodate growth, and support a safe, reliable national airspace system. The reality is, our nation’s airports are vital public utilities with sizeable operation costs. To meet the airports’ individual infrastructure needs the FAA established the AIP trust fund. This program was created as part of the Airport and Airway Improvement Act of 1981 as a means of distributing federal entitlement and discretionary funds to airports that are part of the National Plan of Integrated Airport Systems (NPIAS).

As we continue to watch the debate unfold over the following weeks, it will be interesting to see if there is an increase with future adjustments for inflation or we keep the status quo. There are still many questions to be considered. Per U.S. Code Title 49 USC § 47114(f), the amount of entitlement funds for large and medium hub airports that also collect a PFC, are reduced based on the PFC collection level approved for that airport. For example, if the airport is collecting at $3.00 or less, the amount of entitlements is reduced by 50%. If the airport is collecting more than $3.00, the amount of entitlements is reduced by 75%. If PFC raises to $8.50 or something in between $4.50 and $8.50, how would this further affect the process for AIP entitlement and discretionary distribution of funds? Would there be additional federal money supporting small airports while larger commercial airports can support their operations through PFC?

The Future of Airport Infrastructure

Airport executives are in a position where they are required to plan for future growth, support airlines, support aeronautical activity including the safe and efficient transport of people and goods, and enhance passenger services. How these improvements and services are funded are an integral part of the PFC cap increase debate. Legislators need to decide if an airport is a public asset that is to be supported by the government as an essential and vital piece of transportation infrastructure; or is an airport a business just like any other that is fiscally responsible for their operations? How this on-going debate over raising the PFC is addressed in 2020 will be key to airport infrastructure funding in the future.

4 Things We Learned about Electronic Tolling in New Hampshire

all electronic tolling AET photo from MassDOT

A few weeks ago, we attended the New Hampshire Institute of Transportation Engineers (NHITE) fall meeting (where I serve as NHITE president). Our engineers learned about the history of tolling in New Hampshire, tolling technology, and details on design and challenges at planned All Electronic Tolling (AET) locations in Dover and Rochester.

Electronic tolls are just what they sound like – overhead scanners that connect to an account like E-ZPass to pay your toll. They replace the manned/unmanned booths (barrier tolls) and the need for rolls of quarters or tokens. They help with alleviating traffic that builds up at toll booths during peak seasons. Just like barrier toll booths, though, they have their challenges. Fee collection systems must be properly designed and monitored to ensure revenue is not lost while driver privacy must be protected.

These are all considerations that engineers and system administrators must consider when thinking about implementing AET.

Key takeaways we want to share

  • Collecting tolls is vital for maintaining turnpike assets in New Hampshire; including nearly 90 miles of limited access highway such as the FE Everett Turnpike.
  • AET tolling increases the capacity of the toll facilities and reduces the congestion felt by drivers. They eliminate vehicle conflict points at merge locations and lane changes, which helps to reduce crashes. AET also reduces environmental impacts with a smaller project footprint and by lowering emissions through reduced acceleration/deceleration.
  • Drivers’ privacy is a primary concern; data that is collected by electronic tolls is erased immediately after all successful transactions.
  • Loss of revenue through “leakage” (travelers who go through the tolls without paying) must be minimized so that funds for road maintenance and repairs are available.

Hidden Revenue Potential at Airports

Whether traveling for business or leisure, many of us have experienced firsthand the increase in the number of air travelers. Although fully booked flights are encouraging news for the industry, they also mean higher operating costs for the individual airports. To help defer these costs and become self-sustaining, many airport managers have begun to explore creative revenue generation opportunities.

A study conducted in 2017 by Airports Council International (ACI) estimated that the airports total cost per passenger is approximately $13.69. This value however exceeds the global average of $9.95 for aeronautical revenue received per passenger. While aeronautical revenue per passenger seems to be constant, the airport has the potential to increase revenue by finding creative ways to increase the non-aeronautical revenue associated with each passenger.

Revenue generated by an airport is typically divided into two streams. Aeronautical revenues include those funds generated to the operation and use of the airfield by aircraft or aviation-related businesses. Non-aeronautical revenues relate to those operations and uses that are incidental to the operation of aircraft. Traditional sources of non-aeronautical revenue include parking, rental cars, terminal lease, concessions, restaurants, and advertising. According to ACI, 39.9% of total global airport revenue is contributed from non-aeronautical revenue sources. Successful airport managers understand not only the aviation-related operations of their airport, but also the revenue potential associated with non-aviation operations and business. Some non-aeronautical revenue strategies that are applicable to both commercial service and general aviation airports include:

non aeronautical strategies

As technology advances, additional non-aeronautical revenue sources may also rise and airport administrators must be willing to embrace these opportunities to help defer ever-increasing operating costs and become self-sustaining.

Competitive Grant Writing 101: 7 Tips to “Show You the Money!”

Photo of papers on desk with person writing on them

Competitive grants can be a big help for project owners who are responsible for large, complicated and expensive infrastructure improvement projects.  Whether potential grants originate from federal agencies, such as the USDOT or the EPA, state agencies, or local entities, the competition can be fierce and funding requests typically significantly outweigh what is available. So, you have a great project in mind – what do you have to do to position your project over the tens, hundreds or thousands of others that are pursuing the same pot of gold? Here are some opinions and helpful hints that may guide you to success!

Be Prepared and Get Started Early.

Competitive grant applications require extensive and detailed information and the submissions may have short turnaround times.  If you wait to do your conceptual planning or develop a convincing “purpose and need” for the project until the Notice of Funding Opportunity (NOFO) is issued, you may be too late. For example, the recent $900 million BUILD Grant from USDOT was released on April 23, 2019, and applications were due no later than July 15th – a 12-week turnaround. This may seem like a lot of time, but it disappears quickly considering what needs to be included in a solid application, even if you retain a consultant to assist and do the heavy lifting.  In anticipation of a NOFO being issued, having a completed feasibility study, conceptual plan, project cost estimates, public support and other elements of a strong application can go a long way – there just isn’t time to prepare and collect the information once the NOFO is issued as the application preparation itself can be intense.

Be Objective about Your Project.

Does your project truly check off the boxes that the funding agency is looking for with regard to safety, socio-economic benefits, state of good repair, improvements to quality of life, life cycle analysis, benefit vs. cost analysis, and other important elements? Competitive grant applications such as TIGER, BUILD and others can be time-consuming and expensive to prepare. Make sure you are looking at your project objectively against the required criteria and not simply justifying its worthiness by your personal attachment to its local importance. Answer this – why would the funding agency want to participate?  The funding will only buy so many ribbon-cuttings — so why yours?

Tell the Story of the Project.

Picture this – you are a reviewer of applications in Washington, D.C. and you have a stack of 500 applications to wean down to those deserving further review to eventually make a recommendation of a certain number to the ultimate decision-maker, maybe the U.S. Secretary of Transportation.  The recent BUILD grant application had a 30-page limit for the project narrative – for 500 applications that could total over 15,000 pages of project content to review!  Make it interesting – don’t make it read like an engineering report cluttered with facts and data (not that those aren’t important).  The reviewers aren’t all engineers – some have business backgrounds, while others may have a pure administrative or political background.  Use graphics and maps wherever possible. Sell your project in a way that it meets the funding requirements and tells an engaging story of the positive impacts of local, regional and possibly national importance.

Be Invested and Don’t Just “Take a Shot” and Hope for the Best.

If it looks like the application is presenting a project that will die a quick death without grant funding maybe it isn’t really all that vital and you are only presenting the project for the money. Funding agencies (and politicians) hope your project is important enough that somehow it will move forward even without the grant funding – grant funding would simply accelerate the benefits to the taxpayers.  Your application must demonstrate that there is significant funding in place, or debt service, to be able to fund the project and the grant funding will help that much more to defray local costs.

Don’t Ask for the Moon.

Request the real amount that you need for the project after significant investment from other sources. If 95% of the project costs are proposed to be through the competitive grant funding that may not inspire a lot of confidence in the preparedness of the project owner to be able to move the project forward. For instance, with a set amount of funding to spread around, two $10M ribbon cuttings creates more photo opportunities than one $20M ribbon cutting.  There should be a strategy in the amount requested compared to your other competing interests and funding commitments. Answer this too – if you got the grant funding to offset costs, what would you do with the money that was offset?  What other problem could you / would you solve for the taxpayers?

Last but not Least – Check and Double-Check the Format for the Submission.

Most competitive grant applications have very strict composition requirements including the table of contents, page limits, and font types and sizes, just to name a few. Make sure you are thoroughly familiar with each of these requirements and you are adhering to them during the preparation of the application – not as a final task right before the submission is due.

Submit Early if Possible.

Don’t let technological glitches, like an internet failure, get in the way of your million-dollar request being accepted. Many grant application processes allow the applicant to submit their application electronically and update it or resubmit components up to the deadline published in the NOFO. There may also be registrations, passwords, user accounts or other things like that which should be set up early – make sure those tasks are done well in advance. Nobody wants to be sitting at the keyboard being denied access to the submission website or during a power outage within the hour the submission is due.  Plan days ahead and rest easy.

Grants can make a big difference in the success of your project – but competition can be fierce. NOFO’s are issued throughout the year so know in advance what funding may be available and when.  Being ready and preparing a quality grant application can make all the difference.

The New Hampshire MS4 Stormwater Permit: What’s Next?

Image of a stormwater outfall area as body of water

For our friends in the MS4 communities, hopefully, you completed the Year 1 requirements to meet the June 30, 2019 deadline. This included, among other things, completion of a Stormwater Management Plan (SWMP), Illicit Discharge and Detection Elimination (IDDE) Plan, outfall ranking and prioritization for subsequent outfall investigations, construction site runoff control procedures, a schedule for catch basin cleaning, a schedule for street sweeping, written winter road maintenance procedures, distribute two targeted messages (depending on the community), and develop a Chloride Reduction Plan. So, what’s next?

MS4 communities must continue to work on/update the stormwater system mapping. This includes key elements and features of the stormwater conveyance system, structural Best Management Practices (BMPs), open channels, etc. 2003 MS4 communities have two years (until June 30, 2020) to complete the update of the stormwater system mapping. New MS4 communities as of the 2017 MS4 have 3 years (until June 30, 2021) in which to complete the mapping of their stormwater system. As part of this effort, the initial catchment delineations should be refined as well. Systematic investigation of problem catchments, or high-priority catchments if there are no problem catchments, is to be started. A written catchment investigation procedure must be developed by December 31, 2019.

The investigation of problem and high-priority outfalls starts with a field inspection during dry weather. If dry-weather flow is observed, then further screening is required to determine if there may potentially be illicit discharges present. This can be done using field test kits; however, screening for bacteria requires laboratory testing. The results of the screening will determine whether additional investigation is required to determine sources of illicit discharges. The outfall ranking and prioritization will also be updated accordingly.

Stormwater outfall concrete pipe with water draining out of itGood housekeeping procedures must be developed for permittee-owned facilities, including: develop inventory of all permittee-owned facilities; develop O&M procedures for municipal activities; develop O&M procedures to reduce/minimize/eliminate discharge of pollutants; develop and implement Stormwater Pollution Prevention Plan (SWPPP) for municipally-owned facilities such as maintenance garages, public works yards, salt sheds, transfer stations and other areas where pollutants are exposed to stormwater; and cover salt storage areas. Are you having fun yet?

Public Education and Outreach activities must be continued during Year 2. This involves distributing two targeted messages.

Permittees lucky enough to have discharges to waters with an approved Total Maximum Daily Load (TMDL) have additional activities to complete during Year 2 as well. Permittees subject to an approved TMDL for chlorides must begin implementation of their Chloride Reduction Plan. Permittees subject to an approved bacteria and pathogen TMDL must disseminate public education materials and work on implementation of their IDDE plan. Permittees subject to a phosphorus TMDL must have a legal analysis of their Lake Phosphorus Control Plan (LPCP) completed.

Permittees with discharges to impaired waters without an approved TMDL would be well advised to begin planning for future MS4 permit obligations as well. Impairments to waters without an approved TMDL include: nitrogen, phosphorus, bacteria or pathogens, chloride, total suspended solids, metals, and oil and grease. Did you know that leaf litter contributes phosphorus and nitrogen to stormwater runoff?

Did I mention that the Year 1 annual report must be completed and submitted by the EPA-extended date of September 30, 2019? The reporting period for Year 1 is from May 1, 2018 to June 30, 2019. The reporting period is from July 1 to June 30 for all subsequent years. The EPA has developed a template based on the 2017 MS4 permit that can be used for the annual report. The template can be found here.

The Hoyle, Tanner team of experts is available to assist you as needed with MS4 permit compliance. If you have questions, please contact Michael Trainque (mtrainque@hoyletanner.com) or Heidi Marshall (hmarshall@hoyletanner.com) at Hoyle, Tanner & Associates, Inc.

Heat Safety: 4 Tips to Stay Safe on Construction Sites During Summer

Heat illness prevention graphic of construction worker

Summer is officially here, and although the warm weather brings promises of barbecues, beach days and the hum of AC, working in the summer heat is not something to be taken lightly. For construction laborers and other outdoor workers, the heat can drain your energy and be very dangerous if proper precautions aren’t taken.

According to the Bureau of Labor Statistics’ most recent data, in 2015 over 2,830 American workers suffered from a heat-related illness that required at least one day away from work. In order to prevent more injuries now and in the future, it is important to spread awareness in the workplace about how to stay safe while out and in intense summer conditions. By planning ahead and executing these simple safety measures, you will be happier, healthier and ready to enjoy all the fun that the summer heat has to offer.

Drink Water

Staying hydrated is the single most important thing you can do to prevent heat-related injury or illness. The Occupational Safety and Health Administration recommends drinking water every 15 to 20 minutes even if you are not thirsty. Additionally, anyone exposed to prolonged periods of sweating should balance out their electrolytes by drinking sports drinks such as Gatorade or Powerade. Keep in mind, though, that sports drinks are laden with food dye and sugars, so you can also boost your electrolytes by eating mineral-rich foods like bananas, nuts, yogurt, and dark green vegetables like kale. Coconut water is another good source of replenishing electrolytes. If you can’t carry snacks around, some say that adding a pinch of salt and a squeeze of lemon to your water can have a similar satisfying effect.

Be Cautious of Caffeine

Coffee is an essential part of the day for many Americans. However, all caffeine — whether it be coffee, tea or soda — can be dangerous on a hot summer day if you aren’t careful. This is because caffeine can be diuretic, meaning that it causes water loss in the body and dehydrates you more quickly. Whether or not caffeine is actually a diuretic has been debated over the past few years, but your reaction is also very subjective; someone who rarely drinks caffeine may feel its effects more than a daily consumer, especially on a hot day. Drinking water throughout the day should counter these effects, but be wary of drinking excessive amounts of caffeine, especially while on the job site.

Take Breaks

Do not be afraid to take breaks. No job is worth risking your health over. The heat can be draining, and it is important that you allow yourself the time you need to recuperate. When you do take breaks make sure you find some shade, drink at least 20 ounces of water and reapply sunscreen. For lunch, eat healthy and energizing foods. You will be surprised how much stronger you feel throughout the day.

Know the Symptoms

Excessive heat can lead to heat exhaustion and heat stroke. It is important that you are able to recognize these symptoms and know what to do if the situation arises.

Heat Exhaustion

Nausea, vomiting, headaches, weakness, confusion, dizziness, and cool, pale, moist or flushed skin can all be signs of heat exhaustion. If you or someone you know is experiencing any of these symptoms it is important that you immediately move them to a cooler location and start to loosen any tight or heavy clothing they are wearing. You need to lower the person’s body temperature by any means necessary. Some examples of how to do this include fanning them, spraying them down with cool water or resting wet towels on their skin. If the victim is conscious, start replenishing their fluids by having them drink water slowly (about 4 ounces every 15 minutes). Keep a careful eye on the person and watch for any changes in their condition. If they refuse care, begin to lose consciousness or start to vomit, call 911 or local emergency authorities immediately.

Heat Stroke

Signs of heat stroke include hot dry red skin, confusion, loss of consciousness or convulsions and seizures. Heat stroke is an extremely serious condition and can be fatal, so if you witness anybody experiencing any of these symptoms, call 911 immediately. While waiting for help to arrive, cool the person down as quickly as possible. If circumstance allows, immerse the person up to their neck in cold water. If that isn’t an option, spray the person down or apply ice packs or wet towels to their skin.

For more information on what to do when temperatures rise, download the free Red Cross Emergency App. The app also gives users the option to receive alerts for excessive heat watches, warnings and heat advisories.

We want this summer to be memorable for a lot of reasons, but overheating is not one of them. When working outdoors in hot weather, the most important things to remember are water, shade and rest. Anyone can be at risk for severe dehydration and heat exhaustion, but people who are not used to prolonged exposure to heat typically are at a higher risk of suffering an injury. As things start to heat up this summer, ease your way into your work, especially if you are a new employee. Listen to your body and take the necessary precautions to ensure that you are both safe and successful.

Now get out there and enjoy the sunshine!

MS4 Regulations in New Hampshire Communities: How to Deal with Stormwater

Storm Drain Photo

Whew!! You got that Notice of Intent form submitted (hopefully) to EPA on or before October 1. Now what? Grab a cold one, sit back, relax? Wishful thinking. Now the real fun begins.

Stormwater Sampling For those communities that have not already done so, stormwater outfalls from the MS4 area must be located, mapped and assigned a unique identification number. Then an inspection and condition assessment must be done for each outfall. If you were an MS4 community subject to the 2003 permit, you would have (or at least should have) completed this. However, you are not finished. Mapping completed pursuant to the 2003 MS4 permit must be updated with significantly more detail added per the 2017 MS4 permit. You have 2 years to complete the update. If you are a new MS4 community subject to the 2017 MS4 permit, you need to start this process and complete it within 3 years. For all MS4s, the stormwater mapping must be updated annually; and catch basins, catchment areas, manholes, and other features must be added. You must also complete an outfall inventory and ranking. The ranking is based on potential for illicit discharges and sanitary sewer overflows. Are we having fun yet??

If flow is observed from any outfalls during dry weather, it will be necessary to conduct dry-weather sampling and testing of each outfall in which dry-weather flow was observed in order to determine if there are potentially illicit discharges in the outfall. Outfalls must be ranked as “Problem”, “High-Priority”, “Low-Priority”, or “Excluded” based on known or suspected illicit discharges or sewer system overflows. This is all part of the required Illicit Discharge Detection and Elimination Program (IDDE). Did I mention you need to complete a written IDDE program within one year (by June 30, 2019)?

A number of New Hampshire communities are specifically listed in the 2017 MS4 permit based on discharges to waters with an approved Total Maximum Daily Load (TMDL) and/or based on discharges to certain water quality limited (impaired) waters without an approved TMDL. Approved TMDLs include chlorides, bacteria or pathogens, and phosphorus.

How is your Phosphorus Reduction Plan coming along?
Impairments to waters without an approved TMDL include: nitrogen, phosphorus, bacteria or pathogens, chloride, total suspended solids, metals, and oil and grease. Did you know that leaf litter contributes phosphorus and nitrogen to stormwater runoff?

How is your Chloride Reduction Plan coming along?
The written Plan has to be completed within 1 year (on or before June 30, 2019). There are also specific requirements for public education and outreach as well as public participation including messages and outreach to target audiences.

How are your stormwater regulations?
MS4 communities need to update their stormwater regulations and ordinances (if you already have them) or develop and implement regulations for managing stormwater (if you do not have them).

By the way, did I mention that all of the foregoing has to be addressed in your Stormwater Management Plan? The Hoyle, Tanner team of experts is available to assist you as needed with MS4 permit compliance. If you have questions, please contact me or Heidi Marshall for assistance.

Hoyle, Tanner Engineers Showcase their Knowledge of Asset Management

Asset Management

On September 20, John Jackman, PE and Rychel Gibson, PE will be presenting on the basics of an asset management system at the Sunday River Grand Summit Resort Hotel & Conference Center in Newry, Maine, as part of the Maine Water Environment Association’s fall convention.

The focus of their presentation will be the documentation, organization and data collection for physical assets using tools like Google Forms. By using Google tools  (Drive, Calendar, Maps, and Forms), users can input data for free from a computer, tablet or phone. Among other tasks, John and Rychel will demonstrate how to use Google Forms to fill out daily logs and inspection sheets, and how to use Google Maps to document and track GPS assets.

Physical assets – like pipes, pumps, and valves — can be stressed from over-use, underfunding, and aging. It is the responsibility of the asset manager to know when an asset has reached its useful life. Over the past two decades, practical, advanced techniques have been developed for better managing physical assets. Hoyle, Tanner has assisted close to 40 municipalities, counties and state agencies with their asset management plans system. John Jackman has been involved with asset management for 16 years and joined the New England Water Environment Association in 2004. Rychel is a member of the Maine Water Environment Association and has been integrally involved with developing freeware-based asset management assistance during her time with Hoyle, Tanner.

The Flow of the River: What 2D Hydraulic Modeling Can Teach us about Movement

GIF image of 2D hydraulic modeling showing water under a bridge

Imagine trying to measure water in a beaker or in a measuring cup; it is stagnant and easy to follow the line of meniscus to see if it’s a ½ cup or 3/4. Then imagine measuring water in a river in order to build safer bridges; it tumbles over rocks, it changes speed, it experiences different water levels throughout a season.

Believe it or not, water movement is one of the most difficult phenomenon to solve. Yes, you can apply mathematics or numerical methods to solve complicated differential equations, but there are always some unknowns about turbulent flows (class 4 rapids) where general assumptions are made.

Rivers require intricate numerical models for river-type engineering problems, and I have been accepted to present on these intricate models at this years biennial National Hydraulic Engineering Conference (NHEC) in Columbus, Ohio. The Conference spans a week from 8/27 to 8/31, and I will be presenting on Friday, August 31st.

Per the NHEC website (https://www.ohio.edu/engineering/nhec/), the conference is themed “Advancing Hydraulic Engineering through Innovation and Resilient Design,” and will address the challenges that transportation agencies face to construct, maintain, sustain, and improve hydraulic structures in the physical, natural, social, and economic environments of today and tomorrow. At this conference, I will be presenting on Two-Dimensional (2D) Hydraulic Modeling with Tidal Boundary Conditions.

Modelers typically use computer software packages where you input topography, flows, roughness parameters, and hydraulic structures. The software package uses the input to solve mathematical equations. It seems simple enough, but a modeler needs to have a conceptual understanding of numerical methods and know the limitations of the software package being used.

Whenever you hear the term “3D,” you think of an object in a space that has 3-dimensions, right? Similarly, water moves within a 3-dimensional space, where there is a z-component (up, down), y-component (left, right), and x-component (back, forth). What if I were to tell you that the movement of water in the z-direction (up, down) is not considered?

What would that mean? Well, what that means is that mathematically, we are simplifying a very complicated problem:  we are restricting movement of water to flow/move in 2D, 2-directions (x and y) and that is what 2D hydraulics is all about. Similarly, a one-dimensional (1D) hydraulic model is defined when the y-direction is neglected and water is confined to moving in the x-direction.

2D hydraulic modeling is not that new and has been available in an academia setting since the 80s. But in recent years, tools to develop 2D models have been readily available to engineers. A 2D model can’t be developed for every problem that we tackle, but it allows us to accurately represent actual real world conditions, make less assumptions and judgment calls, and communicate and show visualizations of flow movement to stake holders.

Are you ready for the new NH MS4 Stormwater Permit?

Pond with lily pads

EPA Region 1 issued the revised New Hampshire Small MS4 General Permit on January 18, 2017. Affecting 60 New Hampshire communities, this new permit will make a significant change in stormwater management compliance when it takes effect on July 1, 2018.

This new permit imposes more stringent regulations for communities’ compliance in regards to how to manage stormwater.

Many community leaders have expressed concerns that the overlap with other regulatory requirements and the cost of meeting those requirements may not effectively achieve the desired results, and they are looking for integrated cost-effective approaches to meeting the new regulatory requirements.

Governor Chris Sununu has publicly spoken against the new MS4 permits, saying that they would severely impact municipalities and taxpayers, noting that “additional mandates contained within the new MS4 permit will prove themselves overly burdensome and enormously expensive for many of New Hampshire’s communities.”

If you live in community in Southern New Hampshire, chances are that this change affects you in some way. To see a list of affected communities, please visit the EPA website.

Hoyle, Tanner has experienced staff who are knowledgeable about asset management, SRF loan pre-application preparation, and MS4 permitting.

John Jackman, PE, asset management specialist

 

John Jackman, PE, is Hoyle, Tanner’s premier Asset Management Specialist. Although the CWSRF money cannot be directly used to support the MS4 program, using the asset management program to support documentation of municipal assets will be helpful in setting up a strategy for compliance related to the October 1, 2018 required filing date of the MS4 permit’s Notice of Intent.

 

Michael Trainque, PE, stormwater specialist

 

Michael Trainque, PE, has 39 years of environmental engineering experience.  Michael has been integrally involved in developing model stormwater regulations, identification, assessment and dry-weather sampling and testing of stormwater outfalls, as well as other aspects of stormwater management.

Engineers Week: Girl Day

Girl Day Engineers Week

It’s no secret that there is an underrepresentation of females in the field of engineering. Here at Hoyle, Tanner, we recognize diversity and inclusion as an instrumental part of making sure we are developing the best solutions to our region’s challenges. That is why we are participating in Girl Day, a recognized day of Engineers Week that is specifically geared toward generating awareness and educating young females about the opportunities available to them within the industry.

In 2015, women made up roughly 47 percent of the workforce but only 24 percent were working in STEM careers. Studies from Engineer Your Life & Changing the Conversation indicate that the lack of female interest and presence in the field may be due to the fact that many girls:

  • Do not know what engineering is
  • Think engineers must be exceptional at both math and science
  • Believe engineering is difficult and challenging

The gender gap in the industry can also be attributed to a matter of confidence. Studies show that when asked to assess their math abilities, female students tend to report lower capabilities despite equal levels of class achievement compared to their male counterparts.

There are many ways to encourage young girls to learn more about engineering, whether it be hosting events at your firm, visiting classrooms, or providing extensive access to role models or mentors within the field. However, if we are going to be successful in closing the gap and boosting the number of female engineers in future generations, we need to shift the focus of the conversation.

According to Discover Engineering, the only way to change young women’s thoughts about engineering is to change the way we talk about engineering. It is important to explain to young women that there is no “type” of person who becomes an engineer, and that a potential successful engineer does not necessarily have to be someone who “excels at math and science.” Instead, leaders of the women in the engineering movement suggest we begin to define a good engineer as someone who:

  • Is creative and imaginative
  • Likes to collaborate with others
  • Is curious and persistent
  • Wants to make a difference
  • Enjoys solving problems

By participating in Girl Day, we at Hoyle, Tanner hope to play our part in encouraging young women to study engineering. As a firm, we are proud to celebrate our female engineers and recognize how diverse minds at work help to increase the success of our projects.

Happy National Engineers Week!

Engineers Week Poster

(Image courtesy of DiscoverE.)

In the United States, National Engineers Week is always the week in February which encompasses George Washington’s actual birthday, February 22; President Washington is considered the nation’s first engineer. It is observed by more than 70 engineering, education, and cultural societies, and more than 50 corporations and government agencies. The purpose of National Engineers Week is to call attention to the contributions to society that engineers make. It is also a time for engineers to emphasize the importance of learning math, science, and technical skills.

This year’s theme, “Engineers: Inspiring Wonder,” is a call to recognize the people who create today’s awe-inspiring wonders like cloud-busting skyscrapers and human travel to Mars. Our lives would be very different without daily marvels like clean drinking water, computers, and cars.

Over the next week, we will:

  • Celebrate President’s Day and kick off Engineers Week;
  • Share the passion our employees have for engineering;
  • Visit a local high school to demonstrate the skills engineers use every day;
  • Celebrate Girl Day, a worldwide campaign to introduce girls to the fascinating world of engineering by vising a local Girls, Inc.; and
  • Attend the Engineer’s Week Banquet to celebrate the 2018 NH Engineer and Young Engineer of the Year.

For additional information on engineering or Engineers Week, we encourage you to visit http://www.discovere.org/our-programs/engineers-week

Designing Bicycle Box Systems to Keep Cyclists and Motorists Safe

Green box painted on pavement with bicycle riding on it in traffic

Everyone knows about bicycles. Like any sport, they have a fandom following, from avid Tour-de-Francers to all those dedicated bike-to-workers. Not to mention, it’s practically a rite of passage to learn how to ride one, and it’s the quintessential comparison when talking about things you never forget how to do once you learn.

Despite their popularity around the world, America still shines with its youthful glow in comparison to many historic countries; we just don’t have the same bicycle-laden streets that other countries have grown to cherish. That’s not to say that America isn’t making strides to enhance its bike-ability. Major cities have hundreds of miles of bike lanes, while New York City tops the list at having 1,000 miles.

Though America has some catching up to do, cities have seen overall betterment in roadway safety when communities define where bicyclists should travel on the roads.

One innovative design that’s gaining traction is the bicycle box. From the NACTO website, “A bike box is a designated area at the head of a traffic lane at a signalized intersection that provides bicyclists with a safe and visible way to get ahead of queuing traffic during the red signal phase.”

Bicycle boxes are innovative because they address many safety concerns at once, such as: increasing visibility of bicyclists, preventing “right-hook” conflicts, provides priority for bicyclists, and groups bicyclists into one obvious area, making it easier for cyclists to clear the area quickly.

Recognizing these benefits, Hoyle, Tanner recently designed a bicycle box system on Farrell Street in South Burlington, Vermont, which will become the first approved installation in the State. As Farrell Street is part of the route of the Champlain Bikeway (a 363-mile scenic loop around the lake), the City is dedicated to improving access and safety in this location and throughout the City. At the Farrell Street/Swift Street intersection, the City was particularly concerned that southbound cyclists looking to make a through or left turn would conflict with vehicles turning right to access US 7 & I-189. A bicycle box was the perfect solution. Hoyle, Tanner worked with the Federal Highway Administration (FHWA) and gained interim approval for the City’s use of this valuable tool, which is required for new traffic control devices that have not yet been formally adopted. Partnering with Howard Stein Hudson, Hoyle, Tanner designed the bicycle boxes which will employ special highly visible green pavement markings and thermal or video bicycle detection to reduce collisions and improve safety at the intersection. With this experience, Hoyle, Tanner will look to aid other municipalities and state agencies with this and other emerging traffic control technologies, with a goal of improving the recreational and commuter transportation experience for all users.

What Droughts can Teach us about the Importance of Proper Culverts

July 2016 struck New England with an extreme drought and dry weather patterns for an entire year in most of the region. Many people are seeing the drought disappear as heavy rainfall replenishes those dry wells. Showers are taken a little less guiltily.

Yet ironically, the seacoast areas of Maine and (some) of New Hampshire are still considered abnormally dry for this time of year. The drought.gov website says that the percent of dry conditions for the Northeast is a total of less than 10 percent. In general, around 90 percent have no dry conditions at all. Despite this time of year being dryer for the coast, long-term totals actually appear normal.

So, why the pesky persistence with this abnormally dry issue?

“Much of the Northeast remains drought free with the exception of coastal Maine, which has been plagued by below-normal precipitation over the summer,” Deborah Bathke reported in the National Drought Summary for August 8, 2017.

Lack of rainfall may seem relatively insignificant in the engineering world to some. Too much rainfall can cause road erosion, mud slides, sewage overflows, and building floods (among other glorious things). Too little rain? Aside from a crispy lawn, what could go wrong?

Well, for starters, a dry season can mean that ground water levels are low. Low water levels mean that engineered structures, like culverts, don’t work like they are supposed to. Which can lead to problems for an entire ecosystem.

Culverts are a great example. Culverts allow for water passage — such as streams, creeks and brooks — to move under roads. Many aquatic species migrate during their lifetimes, so in order to do that, they need to be able to swim or wade through water freely. The National Oceanic and Atmospheric Administration (NOAA) explains that incorrectly engineered or installed dams and culverts can contribute to declining fish populations by not allowing continuous water flow and creating a physical barrier to fish passage. Throughout the watershed, there can be several examples of perched road crossing culverts (where a drop in elevation exists between the end of the culvert and the water body) and culverts that are too narrow, steep or collapsed.

As rain levels increase and droughts are ending, aquatic life has the chance to move more freely through these constricted passageways.

The importance of culverts can be partly attributed to the way the water flows.

culverts

 

The New England states have turned their attention to the importance of designing culverts that are eco-friendly for the past two decades, with regulations in place in each of the five states that require certain levels of flows, both high and low, to be maintained through culverts in order to protect migrating organisms. From an article by the US Fish & Wildlife Service of Alaska comes the challenge to make roads more fish-friendly:

“What’s under our roads should ideally mimic what’s upstream and downstream,” the article says. “This helps ensure a seamless transition for fish passing underneath. … So how wide is wide enough? To answer that, we must understand the stream’s range of flows. A stream gauge that tracks water level and documents flood events over time can help.”

When accurate stream gauge data is not available, particularly for the smaller creeks or brooks, engineers must examine the existing conditions and develop assumptions on flows, typically using hydrologic models that are standard industry practice.

In short, as you drive from place to place during your day, take time to notice the road culverts you pass over. They have an important role in keeping an ecosystem functioning at its best, even under drought conditions.

14 Steps for Preserving Steel Structures

Piermont, NH-Bradford, VT Steel Bridge

Preventative maintenance is defined as scheduled work at regular intervals with the goal to preserve the present condition and prevent future deficiencies. On bridge structures, this work is typically performed on structures rated in ‘fair’ or better condition with significant service life remaining. Minor repairs may be necessary to maintain the integrity of the structure and prevent major rehabilitation. Structures that are not maintained are more likely to deteriorate at a faster rate and require costlier treatments sooner than maintained structures; therefore, it is more cost effective to maintain structures to avoid replacement or major rehabilitation needs.

New England’s weather causes extreme conditions for steel bridge trusses, such as flooding, ice and snow. Corrosive de-icing agents are used in the winter, which can accelerate deterioration of exposed bridge elements. Preventative maintenance is critical for steel truss bridges to reach their intended design service life and, therefore, attain the lowest life-cycle cost of the bridge investment. Presented are minimum recommended guidelines for preventative maintenance of steel truss bridges.

Here are 14 actionable maintenance tasks to preserve historic truss bridges:

  1. General: Remove brush and vegetation around structure. Annually.
  2. Bridge Deck & Sidewalks: Sweep clean sand and other debris. Power wash with water to remove salt residue. Annually.
  3. Wearing Surface: Check for excessive cracking and deterioration. Annually. 
  4. Expansion Joint: Power wash with water to remove debris, sand and salt residue. Annually.
  5. Bolted Connections: Inspect for excessive corrosion or cracking of the steel fasteners. Check for any loose or missing bolts. Annually.
  6. Welded Connections: Check for cracking in the welds. Annually.
  7. Truss Members: Power wash with water to remove sand, salt and debris, particularly along the bottom chord. Give specific attention to debris accumulation within partially enclosed locations such as truss panel point connections or tubular members. Annually.
  8. Bridge Seats: Clean around bearings by flushing with water or air blast cleaning. Annually.
  9. NBIS Inspection: Complete inspection of all components of the steel truss bridge. Every 2 years unless on Red List.
  10. Painted Steel: Scrape or wire brush clean, prime and paint isolated areas of rusted steel. Every 2 to 4 years.
  11. Steel Members: Check for rust, other deterioration or distortion around rivets and bolts, and elements that come in contact with the bridge deck which may be susceptible to corrosion from roadway moisture and de-icing agents. Every 3 to 5 years.
  12. Bearings: Remove debris that may cause the bearings to lock and become incapable of movement. Check anchor bolts for damage and determine if they are secure. Every 3 to 5 years.
  13. Exposed Concrete Surfaces: Apply silane/siloxane sealers after cleaning and drying concrete surfaces. Every 4 years.
  14. Bridge & Approach Rail: Inspect for damage, loose or missing bolts, sharp edges or protrusions. Every 5 years.

Actions to Avoid

  • Do not bolt or weld to the structural steel members.
  • Do not remove any portion of the structure.
  • CAUTION! Paint may contain lead.

How Your Community Plays a Part in National Walk to Work Day

Spring has arrived just in time for National Walk to Work Day! Individuals across the country are lacing up their sneakers and hitting the pavement, while communities are taking a more holistic approach to ensuring safe pedestrian and bicycle travel. Many municipalities are introducing the concept of “complete streets”, introduced by the National Complete Streets Coalition, to their design efforts to balance safety and convenience for motorists, transit users, pedestrians and cyclists alike. Currently, there isn’t a single design for a complete street; it represents creating roads that are safe for all users, regardless of age, ability, or transportation method. Growing in popularity, some of the complete streets features are being implemented throughout the state, including:

Traffic Calming
With the growing demand for alternative modes of transportation, traffic calming measures are being introduced on various roadways to ensure safe travel for all users. The use of narrowed throughways, speed bumps/humps/tables,chicanes, and curb extensions (bulbouts) are some of the many features being used in the efforts to slow automobile travel, including the Union Street Reconstruction in Peterborough, New Hampshire. This project also incorporated tree plantings along the medians to beautify the area.

High Visibility Crosswalks
History shows pedestrian crossings existing more than 2000 years ago, where raised blocks on roadways provided a means for pedestrians to cross without having to step on the street itself. In current designs, high visibility crosswalks are incorporated to guide pedestrians and alert motorists to the crossing locations. Six foot wide crosswalks are installed using long lasting plastic/epoxy or paint embedded with reflective glass beads to assist in the crossing markings. In addition to local governments, universities, like the University of New Hampshire, are incorporating these crosswalks on their campuses.

Shared Use Paths
A multi-use path or trail that has been separated from motor vehicle travel and has been established for alternative transportation purposes is another option that is growing in popularity. Utilizing existing right-of-ways to create these travel corridors for pedestrians, cyclists, skaters, equestrians, and other non-motorized users in some instances are also used to observe the natural environment in various communities. Recently, a shared use path was completed connecting Manchester’s and Goffstown’s trail system.

Multi-Modal Intersection
Intersections have the unique responsibility of accommodating and coordinating the nearly-constant occurrence of conflicts between all modes of transportation. Multi-modal intersections focus on intersections where numerous modes of travel come together and the coordination is required for the safety of all users. Utilizing different design features such as corner refuge islands, forward stop bars, and dedicated bike lanes, as used on Manchester Street in Concord, all intersection users can travel simultaneously, safely.

With many communities implementing these design features into roadway geometry, walking to work can be as simple as strapping on your shoes and heading out the door. By walking to work for this nationally recognized day, you will help reduce carbon emissions, get fit, and avoid the traffic jams.

Pi vs. Chocolate Cream

Pi… I did not forget the “e”, I am referring to the mathematical constant, π, for the value 3.141592…, a ratio of the circumference of a circle to its diameter. For some it was junior high and others it was high school, but almost everyone is taught the concept of Pi in geometry class in America. The staggering question asked by so many students over the years is “how do we use this in ‘real’ life?” Well we have answered that question for all of you as it relates to engineering:

When designing bridges many of the structures utilize reinforced concrete to provide the strength necessary to support its daily use by vehicles. For many of our bridge projects, the circle is most often representing the area of reinforcing steel used in the reinforced concrete beam.  We determine the total amount of the (steel) reinforcing to determine the capacity of a structural member such as a beam, deck or slab.

In associated roadway design, Pi is used in a slightly different manner, to calculate curvature. A maximum curvature (minimum radius) is used to ensure adequate sight distance at differing speed limits. This promotes safe vehicular travel by providing a level of comfort and expectation to the driver.

Another application for the mathematical constant is in airfield markings. Their purpose is simple – to safely guide pilots during aircraft take-offs and landings, and while taxiing around the airfield. To create these markings, Pi is utilized when calculating the amount of airfield paint required for runway designation markers, taxiway centerlines and edge lines.

Pi is also used extensively in the calculation of areas of gravity sewers, wastewater force mains, water main pipes, storm drains, drainage culverts and other types of utility pipes. These calculations are used to establish the area of the pipe for the purpose of determining flow velocities and flow volumes as well as other types of hydraulics calculations.

Now that we have proved your mathematics teacher correct, and that someday you may need to know the value of Pi, the obvious question remaining is “what does pi and pie have in common?” My answer is Pi is focused on circles, radius and diameters… and so does pie!

“Climbing” the Memorial Bridge

Bridge inspection is an important part of what we do here at Hoyle, Tanner. It is also a vital part of ensuring the safety of the traveling public across the country. You might not realize it, but chances are every time you get in a car you drive across one or more bridges. Per the federally enacted National Bridge Inspection Standards (NBIS) every bridge, big and small, old and new, needs to be inspected on a biennial basis. As you can imagine, this is a huge undertaking for each state’s department of transportation (DOT), and each DOT is looking to inspect bridges faster, more cost effectively, and in less disruptive ways as to not impact the day to day usage of the bridge.

A dynamic, rapidly growing bridge inspection method is to “climb” the structure using rope access techniques. Rope access can best be pictured as a mixture of rock climbing and bridge inspection. The inspector is suspended from two ropes and can either ascend, descend or climb along the bridge. Certain bridges can often have elements that are inaccessible or uneconomical to inspect with traditional methods, such as rigging or the use of under bridge inspection vehicles. Rope access can be tailored for countless geometric challenges, which allows for a detailed, hands-on inspection of every bridge element. In other words, rope access allows inspectors to go anywhere and see any part of the bridge.

Recently a team of five Hoyle, Tanner bridge inspectors including three SPRAT1 and/or IRATA2 rope access inspectors completed a bi-annual inspection of the Memorial Bridge in Augusta, Maine. This 2,100 foot long, 75 foot high historic deck truss bridge posed many challenges for bridge inspection access. Access from the ground below was limited because part of the bridge is over the Kennebec River, and access from above was prevented by a tall chain link fencing that runs the entire length of the bridge. Most importantly, this bridge is a vital transportation route in the heart of the state capital making closing all or part of the bridge to traffic undesirable. Utilizing rope access techniques, we were able to perform a hands-on inspection of every member of the bridge from below the deck and above the river. Rope access allowed for a faster and more cost effective inspection than the traditional methods typically used.

First Response: Storm Damage Mitigation of BMP Failure Presentation

I didn’t know what to expect. I had been to conferences before, seen many presentations, but never had to give one of my own. I thought, why not, I can do this. I got off the plane in Austin on Monday night and took the bus to the hotel. I had just missed the welcome social hour so I decided to relax before two full days of conference proceedings.

I got up early Tuesday morning to practice my presentation, although I wasn’t supposed to present until the following day. I got ready for the day and attended various half hour presentations about best Management Practices (BMP) Case Studies, Green Infrastructure, and Advanced Research Topics. Over a hundred vendors were gathered in one room promoting their products and answering questions. Tuesday night ended with a gala for all the conference exhibitors, speakers, and attendees. I met various engineers, managers, and product specialists.

Wednesday morning started early, like Tuesday, with me practicing my presentation before my 10:00 AM time slot. I got to my conference room early so I could set up and just as I fumbled through some minor technical difficulties, attendees started filling the room. Ten… twenty… fifty – I could not keep up with the headcount – All I knew was it was a full house. The moderator introduced me by reading my biography and as I stood up, I took a deep breath and started presenting. I knew what I wanted to say. I knew what slide was next. It was just like I had practiced. I had 30 minutes to present; but finished in 20 – a little fast, but I nailed the important discussion points.

I wanted to emphasize the intensity of the storm that caused the erosion at the airport. I wanted to emphasize the magnitude of the erosion along with the length and steepness of the eroded slope. And finally, I wanted to emphasize the various stormwater BMPs that were used in the design of the slope stabilization to prevent future failures along with the short amount of time available to do the design. I explained the various detention ponds and the closed drainage system that we designed to convey the stormwater from the top of the hill to the bottom. I showed details of the detention ponds and swales along with the different types of stabilization we used on the steep slopes.

It was now time for questions. What were they going to ask and would I be able to answer them? Three questions were asked and confidently I was able to answer them. I knew why we did what we did and what the design controls were and could therefore speak confidently about why we came up with the design we did.

And then it set in… it was over and I nailed it. Breathing resumed. It felt good to be done and to feel good about my presentation.

7 Factors in Snow Load Evaluations

The weight of one foot of fresh snow ranges from 3 pounds per square foot (psf) for light, dry snow to 21 psf for wet, heavy snow. When evaluating an existing roof for snow loads, an engineer will want to know the year it was built, the materials involved and the load the roof was designed to support, to start. But there are many other variables that need to be considered when evaluating existing roof loads under snow conditions. Outlined here are some of the many factors that impact the snow load carrying capacity a structure:

  1. Materials & Design:Engineers use the building code formulas to determine the appropriate snow load for their new design.  A detailed study, prepared in 2002, set the ground snow loads throughout New Hampshire and is the basis for all new construction projects.  Structural engineers use various design standards for steel, wood and concrete that include factors of safety and account for serviceability issues such as deflection. Older structures, governed by earlier building codes, may not meet current standards.
  2. Detailing and Construction:The type and condition of the bracing and roofing materials can contribute to (or undermine) its strength. Some older steel framed buildings used a cantilever beam layout to minimize the beam sizes by using the load of one beam to reduce the stress in the adjacent beam. Because snow buildup occurs in an unbalanced manner, roof failures have been attributed to this type of construction. Minor renovations to an existing structure can reduce the carrying capacity when, for example, bracing is removed to add new ducts.  A recent study, published in STRUCTURE magazine, found that the bulk of New England roof failures were related to construction or detailing deficiencies and were not a result of excess snow loads.
  3. Pitch & Thermal Conditions:The slope and type of roof surface determines how much snow is retained on the roof. Flat and low-pitch roofs are more commonly prone to overloading because they hold onto snow more easily than steeper ones. Flat roofs without adequate drainage are at increased risk of failure due to ponding that occurs as a result of excessive deflection. Adding insulation to the structure reduces the heat loss causing less melting, and results in larger loads. Similarly, the absence of any heat will increase the snow retained even more.
  4. Roof Layout Geometry:The location of hips, valleys, high roofs and low roofs, and raised elements – like skylights and dormers – create snowdrifts and therefore factor into determining additional loading. Similarly, the addition of snow guards on a sloped roof change the dynamics of the snow behavior on the roof. Parapets and large roof top equipment can cause snow drifts on flat roofs. The addition of a new structure adjacent to existing structures often create drift conditions that are not accounted for adequately during renovation projects.
  5. Depth and Snow Density:Determining the weight of snow based on depth is not possible unless you know the density of the snow on a particular roof. The density is the weight of the water in a set volume of snow. Snow on a roof will compact over time as temperatures fluctuate and as new snow layers are added to the roof. Rain-on-snow increases the density of the snow thus increasing the weight. Measuring this density is not terribly scientific and is not as important as how the roof is actually performing.
  6. Sun and Wind Exposure:Natural elements such as sun and wind impact how much snowfall is retained on a roof. From a code perspective, 70% of a single snowfall event is expected to remain on a roof under normal wind conditions. Wind and sun can create unbalanced snow load conditions on a gable roof when more snow is retained on one side of the ridge than the other.
  7. Maintenance:Proper, or improper, maintenance plays a role in how well a building will perform under load. Some older roofs suffer from steel beam and connector corrosion, or rotting wood, which reduces the building’s ability to withstand heavy snow loads. Proper maintenance, including repairs to any damage or leaks, is important to ensure the structural integrity of the entire structure.

5 Facts About Sustainable Stormwater Practices

*Note that this post was originally published in 2014 and has been updated in 2020.

In urban and densely populated suburban areas where the highest concentration of impervious surfaces are found, stormwater runoff can be a significant contributor to water pollution. As rain falls in outlying rural areas, the water is absorbed and filtered by the natural vegetation and soil. The impervious surfaces, including roofs, sidewalks, paved parking areas and wide city streets, do not allow the ground to absorb the water and instead is collected in closed drainage systems and often time discharged into nearby surface waters without filtration.

Here we review 5 Facts About Sustainable Stormwater Practices to help communities and agencies that may be planning to develop new “green” infrastructure.

  1. Regulatory Compliance: Stormwater is regulated at the federal level by the Environmental Protection Agency (EPA) under the Clean Water Act (CWA). The CWA “establishes the basic structure for regulating discharges of pollutants into the waters of the United States and regulating quality standards for surface waters.” Thus making it “unlawful to discharge any pollutant from a point source into navigable waters, unless a permit was obtained.” State Environmental Agencies often apply additional requirements beyond EPA minimum standards to further protect impaired state waters. On a local level, some communities have developed Stormwater Management Plans to assist managing discharge from both private and public properties. Local Ordinances are crafted by community officials as an integral part of subdivision and site plan development review and approval processes. New stormwater regulations often require implementation of sustainable stormwater management practices.
  2. Green Materials: “Green” or sustainable stormwater best management practices treat stormwater as a resource to be preserved and maintained, taking advantage of natural processes to clean and filter stormwater runoff.  Vegetation and soil filtration highlight the obvious green materials used, but some methods growing in popularity include permeable pavement, down spout disconnection, rainwater harvesting, rain gardens, planter boxes, tree filters, green roofs, bioswales, as well as land conservation. With the incorporation of one or more of these design features, urban spaces are able to reduce the percentage of impervious surfaces thus reducing the volume of stormwater runoff.
  3. Public-Private Partnerships: State and local governments collaborating with developers on properties within different regions to incorporate Green Infrastructure into the design/redesign will in turn save money via stormwater diversion and treatment by the agencies. Offering tax credits or incentives to the developers is intended to accelerate the adoption of these improved stormwater management practices leading to more extensive implementation statewide.
  4. Funding Availability: Many funding options are available through federal and state agencies including EPA, Departments of Transportation, US Economic Development Administration (EDA), Department of Housing and Urban Development (HUD), National Oceanic and Atmospheric Administration (NOAA), as well as the Departments of Agriculture, Energy and Treasury. Grants available through these agencies will help offset the cost for municipal and private entities to invest in sustainable stormwater collection, filtration and treatment upgrades to existing or redeveloping sites.
  5. Benefits: Environmental – Improperly managing stormwater runoff into surface waters can contain pollutants from the surfaces it is diverted from, potentially causing damage to aquatic vegetation and wildlife. Uncontrolled stormwater runoff can also cause physical damage such as erosion and flooding.  With the implementation of green infrastructure practices, contaminants can be reduced in the receiving water bodies and create healthier environments. Social – Incorporating sustainable stormwater management practices can improve water quality, quantity and aesthetics, thereby enhancing the livability of a community, creating multifunctional landscapes and green spaces, encouraging revitalization, and providing educational opportunities. Economic – The use of green infrastructure may provide incentives to attract investment; reinvigorate neighborhoods; inspire redevelopment; or provide new recreational opportunities.
