What is Construction Manager at Risk?
CMAR is a project delivery method where the construction manager is selected during preconstruction and holds a separate contract from the design team. The CM joins early to provide cost estimating, constructability review and procurement planning, then commits to a Guaranteed Maximum Price (GMP) before breaking ground.
Unlike design-build, CMAR preserves the owner's direct relationship with the architect while still gaining early builder input. The construction manager carries the risk of cost overruns above the GMP, giving owners financial certainty without sacrificing design control.
When to choose CMAR
CMAR fits commercial projects where early cost feedback and design flexibility both matter, which is common in healthcare, civic and corporate construction across Texas.
- You want early contractor involvement but prefer to keep a separate design contract
- Cost certainty via a Guaranteed Maximum Price is a financing or underwriting requirement
- Your project has phased design development with evolving scope
- Public or institutional projects require competitive procurement of trade partners
- You need a builder who assumes cost risk above the GMP through completion
How Formative Structures delivers CMAR
Our CMAR engagements begin during preconstruction with a principal at the table. We align on project priorities, provide iterative cost estimates as design progresses, identify constructability issues while they are still inexpensive to resolve, and develop a GMP based on actual market conditions, not historical assumptions.
During construction, the same principal-led team manages trade partner procurement, schedule control and cost reporting in plain language. With $8M+ bonding capacity, Formative Structures carries the CMAR risk profile that owners and lenders expect from a qualified Houston contractor.

CMAR questions
What is Construction Manager at Risk (CMAR)?
CMAR is a delivery model where the construction manager joins the team during preconstruction, provides early cost and schedule guidance, and then commits to a Guaranteed Maximum Price (GMP) before construction begins. It gives owners cost certainty while preserving design flexibility.
How is CMAR different from design-build?
In design-build, one entity holds both design and construction contracts. In CMAR, the owner maintains a separate design contract while the construction manager provides preconstruction services and then builds under a GMP. CMAR preserves architect-owner direct communication.
When is the GMP established in a CMAR project?
The GMP is typically established after design development is sufficiently complete for accurate estimating, often at 50 to 90 percent design, depending on project complexity. Formative Structures provides iterative cost feedback throughout preconstruction so the GMP reflects actual scope.
