SWG Project 1950’s

About Us

Founded in 1945, in Weslaco, Texas, on the dedication to provide quality engineering, SWG Engineering, LLC has since been a full-service consulting, engineering, and surveying firm assisting the South Texas Region with extensive projects in the Lower Rio Grande Valley. SWG has taken a leadership role in providing quality engineering answers in the Valley through our greatest resource – a dedicated and talented staff. Leadership begins with the principals, who are all Texas-registered professional engineers, registered land surveyors, design technicians, construction engineering inspectors, and our administrative support staff.

During the over 75 years in the field of practice, the employees of SWG have assisted municipalities, counties, political subdivisions, governmental agencies and private industries. Our commitment to our work and clients speaks for itself as 80 percent of our business is from repeat clients.
