Engineering EXCELLENCE

Successful Civil Engineering and construction projects are often defined as much by what you don’t see as they are by the tangible results. The skill, ingenuity, and innovation that underpin a particular project’s surveying, planning, engineering, and construction management success may go unnoticed, yet they’re key components that contribute to the overall value of the completed project to the project’s owner and its many stakeholders. With our headquarters in Cheyenne, Wyoming, an additional office in Fort Collins, Colorado and fully licensed engineers  in Wyoming, Nebraska, North Dakota, South Dakota, Arizona and Colorado, AVI is ideally positioned to partner on projects throughout the Rocky Mountain region.

AVI personnel working on this project have provided excellent service and good responsiveness. Very much team players and valuable as resources.

Marcia Murdock, AML Project Manager

AVI completed a very good report, detailing multiple surfacing options and developed cost estimates for each option — good job!

Kevin Stogsdill, PE-WYDOT Interstate 80 RECON

I was very impressed by the timely efforts including straightening out the problem R/W survey that had stalled the project for years.

Dan Lyons, PE-WYDOT Veteran Road

AVI is one of our best consultants. They have proven they can handle multiple projects at one time. WYDOT would be hard pressed to give AVI a project they could not handle.

Cliff Spoonemore, PE-WYDOT Snowy Range Road

I was impressed with your knowledge of the reporting requirements and processes, as well as how well you prepared for the pre-bid meeting and pre-construction meeting.
