NOW PART OF QAI
Same lab, same team, wider reach.
HGEI recently joined QAI Laboratories, pairing three decades of geotechnical and materials testing experience in Orange County with QAI’s national testing, inspection, and certification network. The technicians, the lab, and the point of contact stay the same. The resources behind them just got bigger.
“I felt it was important to pass the HGEI business along to a group that will continue to take care of our clients and develop the company’s services.”
— Don Harrington Jr., CEO, HGEI
