Capabilities
Divisions 1 through 9, self-performed.
GQC is a true full-trade general contractor. We staff our own field crews for the structural and envelope work that defines a project, and we manage every other trade through licensed, vetted partners — all under one prime contract, one schedule, one point of responsibility.

Sector Mix
Primarily commercial. Approved for residential.
The majority of our work is institutional and commercial — transit stations, schools, public housing common areas, community centers, agency facilities, and infrastructure.
We are approved and equipped to take on residential scopes where the client requires the rigor of a public-sector general contractor, including occupied-building renovations.
