Civil construction
& sitework in DFW.

Excavation and earthwork.

Clearing, excavation, rough and fine grading, building-pad preparation and associated demolition. Haul routes, import and export, disposal and unsuitable materials are reviewed against the site information.

Underground utilities.

Utility installation coordinated with the civil plans, existing utility locations, connection requirements and inspection sequence. Utility ownership, testing, permits and responsibility for tie-ins must be defined.

Concrete paving and site concrete.

Parking lots, curbs, gutters, sidewalks, approaches, equipment pads and foundations. We review the interface between grading, subgrade preparation, utilities and concrete placement.

Coordinated civil site packages.

Small-to-mid civil packages for general contractors, developers and commercial owners. Share the full drawings so exclusions and trade boundaries are understood before individual scopes are priced.

A bid starts with current plans.

Send the project location, civil and structural drawings, specification revisions, geotechnical information when available, quantities, bid deadline and construction schedule. Identify surveying, permits, testing and inspection responsibilities, proposed payment terms and any owner-supplied or separately contracted work.

Unfinished grading, unknown utilities, groundwater, access restrictions, unsuitable soils and plan revisions can change the work. We identify these conditions during scope review and establish how changes will be handled.
