What G3 Quality does

G3 Quality, Inc. is a California-based construction quality management and materials engineering firm founded in 2013 by Chris Gerber (CEO) and Susan Pierce (President). The firm delivers quality assurance/quality control, pavement engineering and design, materials design (HMA and PCC mix designs using Superpave, Hveem, Marshall, and Balanced Mix Design methods), construction inspection, and laboratory testing services for infrastructure projects including highways, airports, ports, transit systems, and water/wastewater facilities. Operations span four regional offices (Cerritos HQ, Bakersfield, Redlands, Sacramento) augmented by a fleet of mobile testing laboratories that enable on-site rapid strength concrete testing across California. The firm holds certifications from Caltrans, AASHTO, CCRL, Army Corps of Engineers, and AMRL, and operates proprietary software called QualityConnect™ that delivers real-time project data to clients.

G3 Quality serves four primary customer segments — government agencies, contractors, design firms, and construction managers — through an enterprise field sales motion, with all named customers being public sector entities (Caltrans, SBCTA, City of Lancaster, Brackett Field Airport, Friant-Kern Canal, I-5 corridor). The firm is a certified California Small Business Enterprise (SBE) across state, Metro, and City of LA programs, allowing access to set-aside procurement. Revenue is generated through professional services contracts structured on a project-by-project basis (pricing not publicly disclosed), with services including quality program management, materials consulting, mix design development, field and laboratory inspection, and inertial pavement profiling using ASTM E950/AASHTO R57-compliant systems.

The company has pursued geographic expansion (Northern California via Sacramento in 2021), invested in proprietary technology (QualityConnect™), and cultivated industry influence through active participation in the Caltrans Expert Task Group, CalAPA, APWA, and the California Transportation Foundation. In 2019, G3 Quality was recognized as a Zweig Group 'Best Firm to Work For' and one of the Top 100 fastest-growing Hot Firms in the A/E/C industry. Headcount has grown from 80+ employees in 2020 into the 101-250 firmographic range, though the firm has not disclosed revenue, raised external funding, or announced material acquisitions.
