Lemartec

Lemartec is a design-build construction firm founded in 1979 that delivers complex projects through engineering, procurement, construction management, field engineering and specialised trades. It operates within MasTec's General Building group, combining its own design-build heritage with the scale and financial resources of the parent company. Its work spans industrial, aviation, power, transportation, education, commercial, sports and entertainment projects, as well as mission-critical facilities, the category that covers data centres and comparable critical infrastructure.

The firm's delivery model is built around cross-functional coordination: engineering, procurement, construction management, field engineering and specialised trades are integrated so that changes are identified early and project schedules are held. On-site field engineering and trade execution emphasise safe project delivery and workmanship. Client feedback cited by the company points to clear communication, coordination, early resolution of issues and adherence to schedules.

International reach is available through MasTec's international capabilities. The company reports that 60% of its projects include Hispanic- and minority-owned businesses, and that more than half of its workforce and leadership are of Hispanic heritage. Safety is treated as a core value rather than a priority, supported by safety weeks and field practices; teamwork, communication and a family-founded commitment to excellence are cited as defining features of how the firm works.
