Project Summary

Hoyle, Tanner was retained by Summit Land Development, LLC to provide civil/site design services for two new office buildings, totaling 91,310 sq. ft, at 183-185 International Drive at the Pease International Tradeport in Portsmouth, NH. The larger of the two buildings will be a new office location for Sprague Energy. The site design incorporated a second building and associated parking for future construction so the project could undergo the permitting process only once. The existing 8.8+ acre site has grade changes up to 30 feet and contains numerous mature oak trees. Hoyle, Tanner worked closely with Summit Land Development, the Pease Development Authority and the City of Portsmouth to design the site so as to preserve the site’s natural beauty and retain at least six of the large oak trees. Hoyle, Tanner also provided construction administration services for the project.
