The AVI Advantage

Unlike typical engineering firms, we offer the additional advantage of truly personal and highly collaborative project support. Since our founding in 1979, our service model includes individualized, hands-on attention from our principals to ensure engineering excellence, a successful project outcome and uncompromised client satisfaction.

MEET THE PRINCIPALS

AVI’s nine principals bring extensive experience across a wide range of engineering disciplines and project types. Supported by a team of seasoned engineers, AVI approaches every project with a client-focused mindset and a commitment to practical, efficient solutions. From initial planning and design through permitting, bidding, and construction support, AVI’s leadership team delivers successful engineering solutions tailored to each project’s specific needs, budget, and schedule.
