Who We Are & What We Do

Guzman & Muñoz Engineering and Surveying, Inc. (GMES) has been providing professional engineering, surveying, planning, and construction management services in South Texas for over 39 years. GMES was established in 1973 in the City of Harlingen, under the name of Guzman & Galindo Inc. In 1974, Guzman & Galindo, Inc. became Guzman & Associates, Inc. In 1994, Guzman & Associates became Guzman & Muñoz Engineering and Surveying Inc (GMES), under the direction of the current owner, Mr. Jose L. Munoz, P.E., S.I.T.

Presently, GMES’s new corporate Headquarters is located in Mercedes, Texas right off Expressway 83. GMES’s presence has progressively increased throughout the years in South Texas. To further enhance our level of service, GMES has Satellite Field Offices located in McAllen and Harlingen. The basis for efficient communication between our offices was started in the early 1990’s. At that time, GMES implemented the use of a networked computer system. This enabled GMES to implement and use GPS surveying equipment, aerial mapping, and CAD. Because GMES always uses the latest and most advance technology, in the office and in the field, it is our goal to give our clients the most accurate, easy to understand and expeditious product possible. GMES is always upgrading our field collection equipment. Our field crews are presently using ROBOTIC REMOTE CONTROL TOTAL STATIONS, SCANNERS, DIGITAL LEVELS, and DATA COLLECTORS. By doing this, GMES can eliminate the possibility of human errors. These tools placed GMES in a leadership position to perform large surveys and topography based projects.

GMES strives to provide high quality professional services within the agreed time frame. We accomplish this through our personnel, field equipment, transportation, and vanguard office equipment. A fleet of vehicles owned by GMES ensures reliable transportation to address GLO related matters outside our offices. Further, our state-of-the-art data systems serve to standardize our work, and to facilitate data storage, retrieval, and communication between our offices resulting in accurate, precise, and timely delivery of our services to GLO.
