DNT Construction — Three Texas Offices, One Civil Contractor
DNT Construction LLC is a Texas heavy civil general contractor founded in 2009 and headquartered in Round Rock, TX. With three offices across the state — in Austin (Round Rock), San Antonio, and Houston (Katy) — DNT delivers mass grading, underground wet and dry utilities, concrete and asphalt paving, retaining walls, mobile rock crushing, and data center civil sitework to developers, general contractors, and municipalities across the full Texas market.
DNT's 1,400 team members and 800+ owned heavy equipment units are positioned to mobilize quickly to projects across every major Texas metro without extended haul costs or rental delays. A single contractor for the full civil scope — grading, utilities, and paving — eliminates the coordination risk that drives schedule overruns when multiple subcontractors share a site.
