Owner's Representative & Construction Management in Greater Boston & New England
Terrapin Construction Group serves as owner's representative and construction manager on Greater Boston projects from 50 Milk St, 16th Floor, Boston, MA 02109. When an owner wants a builder's eye on the table without self-performing, TCG protects budget, schedule, and quality from preconstruction through closeout.
TCG brings hands-on construction-administration experience to the role. On Massachusetts cannabis facilities, including Elevated Roots in Kingston (12,000 SF), Mass Medicum in Holbrook (60,000 SF), and BVC in Bellingham (20,000 SF), TCG provided construction administration, the same oversight discipline owner's-rep clients rely on: reviewing the work, holding the schedule, and keeping the budget honest.
As a builder, TCG levels bids apples-to-apples, catches scope gaps before they become change orders, and reads a GC's schedule the way a GC does. Read what developers lose when the GC relationship breaks down and our guide to selecting the right commercial GC.

What Does an Owner's Rep Cost in Boston?
Owner's representative and construction management fees typically run as a percentage of construction cost or a fixed fee, scaled to scope, from preconstruction and bid leveling through construction administration and closeout. The fee is usually a fraction of the budget it protects.
| Scope | Boston Range |
|---|---|
| Owner's rep (full scope) | 2-5% of construction |
| Construction management (agency) | 3-6% of construction |
| CM-at-risk | varies by GMP |
| Preconstruction / bid-leveling only | fixed fee |
The value is risk reduction: a leveled bid, a held schedule, and a protected budget. Use the estimator above for a construction-cost range, or read our guide to reading a commercial GC bid.
