Acosta Sales Building
Marlboro, MA

A new six-story 120,000 SF office building was constructed into the hillside of a sloping site. The first floor slab was used as a diaphragm to transfer interior soil loads to the sidewalls of the basement. To accommodate meeting rooms at the first floor level, four interior columns were transferred. Due to headroom constraints, a Vierendeil moment frame was utilized to transfer the vertical loads and resist lateral seismic and wind loads. Lateral bracing was incorporated in one axis of the building by utilizing stair and elevator walls.
