This 16-story tower is replacing an existing site building as part of the City of Cambridge’s continued effort to transform Kendall Square. Bala is the MEP/ FP engineer for both the Core and Shell building and the interior fit-out for a confidential technology client set to fully occupy 325 Main Street.

Focused on bringing culture and connection to Kendall Square, 325 Main will feature a large atrium space as well as multiple building connectors to the neighboring building, Five Cambridge Center. 325 Main will further enhance neighborhood connectivity and the pedestrian experience through a redesigned Green Garage Rooftop Public Garden, as well as an integrated MBTA headhouse serving the Kendall Red Line T-Station. Bala has been involved in the coordination of all of 325 Main's dynamic site enhancement efforts. To significantly reduce energy consumption of the building, Bala designed rooftop high efficiency magnetic bearing chillers.

Bala is also providing engineering expertise for the entire 340,000 SF office portion of the building, which is inclusive of open and enclosed office space, large assembly areas, commercial kitchen and cafeteria areas and collaboration areas. Due to the high occupancy and amenity spaces, special consideration was placed in regards to supplemental cooling and ventilation. Bala designed an Active Chilled Beam HVAC system to improve energy efficiency, while yielding energy cost savings, uniform temperatures and improved air quality for the space.

Bala's technology group designed and specified the base building access control system, in addition to the surveillance system including network video recording equipment and the security communication system for the base building.
