Cambridge steel work is dominated by two buyers: the life science market around Kendall and Alewife, and homeowners renovating triple-deckers and Victorians in Cambridgeport, North Cambridge and Mid-Cambridge.
The lab work is about vibration, coordination and off-hours access. The residential work is about rigging steel into buildings with no driveway and a street you cannot park a crane on.
Permitting and access
Cambridge Inspectional Services requires stamped structural drawings for load path changes and inspects before close-in. Cambridge is aggressive about construction management plans, street occupancy and neighbor notification, and crane setups on residential streets need approvals with real lead time. On lab projects, the property's own facilities and EHS review typically sits on top of the municipal permit.
Typical local scopes
- Rooftop and interior equipment support steel for lab buildings
