The new building is located on Water St. in downtown Exeter at the site of a former parking lot. Due to the location of the property (abutting a bank on one side, town hall on the other and a church behind), the construction was completed in three phases. Phasing of the project was designed to keep the abutting bank in full operation during construction. With the construction nestled between buildings in downtown Exeter, a helical shoring system was used so foundations could be dug and poured without affecting the nearby buildings. Using the helical shoring system, the foundation excavation was dug in stages. The helical shafts were screwed into the soil and a large washer placed over the shaft. A layer of shoring fabric was installed over the washer with an additional washer anchored in place to secure the fabric in place. Once this layer was secure, the next level would be dug and anchored. With the foundations complete, the helical shoring system remained in place, buried with the foundation backfill.
The new four-story, 32,600 s/f building includes 2,600 s/f of retail space on the first floor and 30 mixed-income apartment units on the remaining three floors with a structural steel and concrete parking deck. The building was designed by Archetype, PA of Portland to fit in with existing structures in the area, with brick veneer and precast concrete, and was designed to meet Energy Star standards for mixed market rate and subsidized rate apartments.
