Construction Management at-Risk
Langston Construction Company delivers construction management at-Risk. We join early as your construction partner, commit a guaranteed maximum price, and build the highest-risk heavy civil scope with our own crews while managing every trade.
What Langston delivers under CM at-Risk
As construction manager at-Risk, we hold the trade contracts, commit a guaranteed maximum price, and build the highest-risk civil and structural scope with our own crews. Heavy civil and industrial construction, managed to one price.
Guaranteed maximum price
We commit a GMP early, so the owner has cost certainty while the design is still being finalized.
Early construction input
We join in preconstruction to drive constructability, budget, and schedule before the drawings are complete.
Heavy civil and site work
Mass earthwork, grading, and site development built by our own crews as the highest-risk scope under the GMP.
Concrete and structural steel
Cast-in-place foundations and structural steel to ACI 318, AISC 360, and AWS D1.1.
Trade contract management
We hold and manage the trade contracts, so the owner has one accountable construction partner.
Open-book cost control
Open-book cost control gives the owner full visibility into buyout, contingency, and realized savings.
