Nauset Construction has begun foundation work on Phase Two of the National Guard Bureau’s new Joint Force Headquarters at Hanscom Air Force Base, Lincoln, Mass.
When finished, the four-story, 80,000-sf office building will connect to the existing 193,000-sf facility and is anticipated to be completed by May of 2013.
The construction of the building and connections to the existing facility have been well coordinated by Nauset’s BIM Management Team, which used 3D modeling to detect structural clashes.
The new facility will have its own air handling units and heating and cooling systems, but the water, fire protection, and electrical systems will be central to the two phases.
Designed to resist the effects of earthquake motions, the facility will house classrooms with raised computer access flooring, heated storage and vehicle ready work bays. The foundation will consist of reinforced concrete footings and floor slab with steel framed masonry walls, aluminum windows, and a metal paneled roof system with integrated gutters. The HVAC system will include three 2,000 MBH gas fired boilers, two 140 ton electric air-cooled chillers and air handlers with multiple zones.
Additional building features will include auxiliary power, fire detection and suppression, security access and surveillance and intrusion detection systems. Extensive hardscaping (roadways, ground level parking, an amphitheater with tiered seating, pedestrian walkways) and landscaping is also part of the project’s scope of work. The LEED Silver rating will be achieved by utilizing energy efficient MEP systems and controls, as well as bio-swales to reduce storm water runoff. Project challenges include close coordination with all subcontractors due to the highly sensitive, occupied and restricted site location. BD+C
