Our story began as a family-owned and operated Design-Build and Construction Management firm specializing in industrial, energy, aviation, and commercial projects. Since the 1940s, the Garcia-Tuñon family has focused on the importance of design and value engineering as a critical success factor for each and every project. This commitment to quality from the pre-construction phase stems from our founder’s belief that an integrated approach to design and construction is the best way to ensure a successful project for our clients.
When Guillermo Garcia-Tuñón Sr., P.E., fled Cuba in 1960, he, his wife and nine children were forced to leave everything behind. That included a flourishing engineering and steel fabricating company he had spent a lifetime building, and which served the Island’s booming sugar industry, as well as some of the world’s largest corporations including Firestone, Glidden Paint, Bacardi Rum, Telemundo Studios, ESSO Standard Oil, U.S. Rubber, Polar Beer, and Goodrich Tires. After eight years in Spain, the family moved to the United States where, together with his sons, Guillermo Jr. and Jose, founded Lemartec Engineering and Construction Corporation in 1979, today known as Lemartec Corporation.
Today, we are proud members of the MasTec family. Our proud history and heritage rooted in family values and safety awareness, made it all so natural for both companies to unite. Our company culture fosters trust and creates value for all stakeholders – our clients, employees, business partners, the community and the environment.
