What we do in Clayton

We self-perform the heavy civil scope that gets Clayton sites pad-ready — every phase coordinated by one team, one schedule, one accountable contractor.

01.

Preconstruction Services in Clayton

Getting in early makes all the difference. We partner with general contractors, civil engineers, and developers during design — not after bid day. Using AGTEK 2D cut/fill takeoffs and 3D earthwork models, drone-flown topo verification, and HCSS HeavyBid estimating built on real production data, we help shape smarter, more cost-efficient sites: balanced mass grading, minimized export, rock identified early, and utility routes value-engineered before they're drawn in stone.

  • Value engineering & constructability review
  • AGTEK 2D cut/fill takeoffs & site balancing
  • 3D earthwork modeling & visualization
  • Drone topo & existing-grade verification
  • HCSS HeavyBid estimating with real production data
  • Mass grading optimization & haul-off reduction

The Clayton Advantage

Built for Clayton.

From the Centene and Centennial Plaza towers downtown to Shaw Park, Concordia Seminary, and the Forsyth/Hanley corridor, Clayton sitework happens around people — judges, executives, and residents who notice every truck. Our crews stage tight, coordinate with city PD for lane closures, and keep Clayton clean through every phase.

Clayton is the St. Louis County seat and one of the region's most demanding job sites — tight downtown blocks, occupied corporate towers, and zero tolerance for schedule slip.
