Central Artery Vent Building

Construction of Vent Building No. 4 included a 310-car parking garage with retail space, renovations to the MBTA’s Haymarket Station and utility relocations. The garage was partially constructed over the existing MBTA station, which remained open and operational throughout construction. Deep excavation for concrete ductwork was 120-ft below grade. DOC served as general contractor in a joint venture with Walsh Northeast.
