Mc Mahon Contracting LP

McMahon Contracting, LP is a heavy civil contractor based at 3019 Roy Orr Boulevard in Grand Prairie, Texas. Established in 1993, it works for the Texas Department of Transportation, municipalities across the Dallas-Fort Worth area and private developers, and it has received the workers' compensation insurer Texas Mutual's safety award in each of the last four years, an honor extended to roughly 200 of some 72,000 policyholders.

The company's disciplines follow the sequence of a roadway project. Excavation and stabilization crews prepare subgrade with more than 25 years of experience in North Texas soils and the utilities buried in them. Utility crews relocate and install water mains from small residential services up to three-foot concrete cylinder mains, sewer from four-inch laterals to trunk lines set 20 feet down, and storm drainage from 15-inch pipe up to multi-span box culverts, along with manholes, lift stations and lined drainage channels. Structure crews build inlets, headwalls, retaining walls and cast-in-place culverts, and the company takes on bridge work.

Paving is concrete. Slipform machines produce roadway pavement, and crews also pour parking lots, sidewalks, curbs, driveways, exposed-aggregate and specialty finishes, and utility patching. A restoration crew closes out punch lists.

Recent projects include Bailey Road in Sachse, for which the city issued a proclamation in 2026, Golden Triangle and FM 1220 in Fort Worth, runway improvements at Grand Prairie Municipal Airport, street rehabilitation in Euless, and roadway work in Mesquite, Wylie, Waxahachie and Prosper. The company publishes its full management and superintendent roster and recruits with a benefits package that includes health coverage and a 401(k).
