What Alliance Geotechnical Group does
Alliance Geotechnical Group, Inc. (AGG) is a Texas-based professional services firm headquartered in Dallas that delivers geotechnical engineering, construction materials engineering and testing (CMT), construction inspection, and forensic studies for public and institutional clients. Founded in 1999, the firm operates six branch locations across Texas (Dallas HQ, Fort Worth, Frisco, Longview, Huntsville, Houston) with a technical staff described as 150+. Core capabilities include subsurface investigation, drilling, foundation analysis, roadway/transportation studies, specialized laboratory testing (consolidation, permeability, triaxial, Proctor, CBR, crosshole sonic logging), QA/QC inspection, and forensic investigations of foundation, pavement, and building failures. Differentiated equipment and process capabilities include in-house drilling rigs, fully staffed accredited laboratories (AASHTO R18, A2LA ISO/IEC 17025:2017, USACE validation, TxDOT), and field instrumentation for vibration monitoring, inclinometers, settlement systems, and piezometer monitoring.
The firm's revenue model is project-based professional services fees, with custom quote-based pricing tied to scope, complexity, and service requirements, billed per project engagement rather than subscription. Its go-to-market is enterprise field sales — direct engagement by professional engineers and a dedicated Business Development Manager with government agencies, municipalities, school districts, water/wastewater utilities, transportation authorities, and airports. The named customer base spans the Cities of Dallas, Fort Worth, Frisco, Plano, McKinney, Denton, Irving, Richardson, and Little Elm; universities (UT System, SMU, UNT, Sam Houston State, Dallas Community College, Tarrant County College); water authorities (Dallas Water Utilities, Tarrant Regional Water District, Trinity River Authority, North Texas Municipal Water District); and transportation infrastructure owners (TxDOT, NTTA, DFW Airport, Dallas Love Field, DART). AGG is an independent, employee-owned firm with a profit-sharing structure and Texas DBE/MBE/SBE certifications (TBPELS F-1970); the leadership team comprises President Robert P. Nance, Senior VP Frank Shirazi, and VPs Mark J. Farrow, P.E., and Michael D. Roland, P.E., supported by a branch and department manager network across Texas.
