Geotechnical engineering is an art and a science and can have significant project performance, safety and cost consequences. Due to the technical nature of our business, all of our geotechnical engineers have graduate degrees in the specialty, unlike many of our competitors. We understand and apply, as appropriate, the latest engineering design and analysis techniques. However, we understand the intrinsic variability of soils and resultant limitations in the application and use of theory. Therefore, we also rely heavily on our most important asset – experience. We understand construction related to earthwork, foundations, and pavement, and our influence on cost. Utilizing our technical skills, significant experience with area soils, and understanding of construction, we continually strive to provide pragmatic, cost-effective geotechnical solutions. Our clients and our business depend on it. 


Industry Accreditations

High quality data is critical to engineering decisions in the office and in the field. Our laboratory is
accredited by A2LA (American Association for Laboratory Accreditation, Certification # 2718.02) allowing a comprehensive range of geotechnical and construction materials tests. Laboratory operations and equipment calibration are conducted in strict compliance with A2LA and the GES quality manual. Laboratory personnel undergo extensive and continual training. Testing is performed in accordance with ASTM, TxDOT, or other appropriate standards.


GES is also accredited by AASHTO (American Association of Highway and Transportation Officials). Results are reviewed and assessed daily by engineering staff for accuracy.​​ The AASHTO Accreditation Program (AAP) is the largest accrediting body in the construction materials industry. In addition to being an AASHTO-accredited laboratory, GES has proven their commitment to quality and can set themselves apart from their competitors.
