Innovators since 1988

In the 1980s, ITAC founder, Sidney Harrison (retired; pictured right front center), was a senior project manager at Allied Chemical, managing multi-discipline projects with multi-million-dollar budgets. He felt the project execution model was cumbersome, disjointed, and costly. He needed an integrated design-build partner to deliver turnkey processes, facilities, and utility systems. In 1988, Sidney borrowed $5K from his brother and founded ITAC with a dream to innovate the project delivery process and to provide industrial clients with total project solutions for their most complex problems.

But dreams are only realized when you have the right team in place. We are grateful to our clients for trusting us with their business and to our employees for making our dreams come true.

Headquartered in Chester, VA, ITAC is an ENR-Ranked Top Design Firm with over 30 years of design-build experience, a nationwide footprint, and 500+ employees operating from 6 offices in the Mid-Atlantic and Southeast regions. Thanks to our ITAC family we have a rich history, but the best is yet to come. Dream on.
