Terrapin Construction Group

Terrapin Construction Group, known as TCG, is a commercial general contractor, design-build firm and owner's representative headquartered in Denver, Colorado. It says it is licensed in all 50 states, has built in 38, and works through vetted subcontractor networks in more than 50 metro areas, with typical contracts of $1 million to $30 million. Cannabis is one of 14 sectors it serves, alongside hospitality, healthcare, data centers and cold storage. The firm self-performs insulated metal panel installation, with more than 1 million square feet installed, along with pre-engineered metal building erection. Its pages quote total project value as both $200 million and $250 million.

Its Massachusetts cannabis page lists The High End in Worcester, a 25,000-square-foot full general contract with panel installation, and Lazy River in Dracut, a 30,000-square-foot design-build cultivation and dispensary project, plus work in Lowell, Kingston, Abington, Holbrook and Bellingham ranging from panel installs and construction administration to a 3,800-square-foot design-build dispensary. Elsewhere it lists a 50,000-square-foot panel and urethane-cement flooring package for a cultivation facility in Minneapolis. TCG says it builds METRC-ready security and access control and prepares facilities for Massachusetts Cannabis Control Commission inspections.

Buyers can run a free online cost estimator, send an existing bid for free review, or book a call; TCG does not publish fixed pricing. It also offers owner's representation without a construction contract, which suits an operator that has a builder but wants independent oversight of budget, schedule and change orders. Its site is heavy with cost guides and calculators, and leadership names appear only through linked profiles, so buyers should confirm the team assigned to their project and ask for references from the named Massachusetts jobs.
