Project Summary

The US State Department moved into the former Liberty Mutual office building to consolidate its passport processing operations at the Pease International Tradeport. The 850-employee center processes 40% of all US passports and with new travel requirements taking effect in 2010, the demand for passport services has increased. This increased demand necessitated an expansion of the facility and parking to accommodate an additional 150 employees and a new public passport counter.

Hoyle, Tanner provided civil design services for the 25,000 square foot building expansion and 180 space parking lot including site layout, grading and drainage, permitting and site plan approval through the Pease Development Authority and the City of Portsmouth. The building addition was constrained by sensitive wetland areas that required creative stormwater management solutions. The new parking lot incorporated low impact development features including multiple bioretention areas, which help reduce the rate of runoff, filter out pollutants, and facilitated infiltration of water into the ground. The site was permitted through the newly adopted New Hampshire Department of Environmental Protection regulations.

Hoyle, Tanner also provided construction administration services which included response to contractor Requests for Information, and weekly site visits during construction. The building was completed on time for the increased first quarter 2011 traffic in passport activity and supports 1,000 employees as part of the State Department’s ongoing effort to improve customer service in this vital area.
