Lemartec is a design-build construction firm, part of MasTec's General Building group, delivering complex industrial, aviation, power, and other projects since 1979.
Lemartec is a design-build construction company founded in 1979 that delivers complex projects across industrial, aviation, power, transportation, education, commercial, mission-critical, and sports and entertainment markets. It operates as part of MasTec's General Building group, combining its own design-build heritage and technical experience with MasTec's scale, financial backing, and international capabilities.
The company's work spans design-build project delivery, construction engineering, procurement, construction management, field engineering, and specialized trades. Teams work closely across these functions to identify and resolve changes early, keeping project schedules on track and workmanship at a high standard. Client testimonials note clear communication and coordination on projects.
Safety is treated as a core value rather than simply a priority, reflected in safety weeks, field practices, and an emphasis on safe project execution. Teamwork and communication shape how teams approach complex work, and the company describes itself as founded on family values and a commitment to excellence.
Hispanic heritage is central to Lemartec's identity: more than half of its workforce and more than half of its leadership are of Hispanic heritage, and Hispanic- and minority-owned businesses are included in 60% of projects. The company states a continuing commitment to inclusion, diversity, and supplier diversity.
