After receiving the necessary funding and permitting, this three-story, 42,000 square foot building project was underway. This public safety facility houses office facilities for employees, an evidence lab, records center; fitness center, firearms practice range, emergency operations center, and a 911 call center for the City of Bangor. To allow for future expansion, it was designed for the addition of a fourth floor.
The concrete foundation system for this structure was complex since it was to be constructed over non-compacted and contaminated materials. Given this design constraint, two-way slab supported by interi
or and exterior grade beams were designed to span multiple pile cap groups. The contaminated materials were encapsulated with a heavy vapor barrier and a complex passive venting system was installed to ensure that
the indoor air quality was not compromised.
