Larimer County Road 31

Contractor began rockfall scaling using a pneumatic rock hammer mounted on a model 350 trackhoe and a 470G trackhoe with a bucket.  Contractor removed rock outcrop located right of Sta 3+75 and began scaling unconsolidated rock from north to south from Sta 4+00 to 2+50.  Contractor also placed plastic pedestrian fabric to restrict unauthorized personnel from the work zone.


AVI is excited to begin the construction of another Larimer County project.




They were particularly good working with the contractors. The skillset of the group was particularly strong with civil engineering and road/drainage designs, but not quite as strong in natural channel design principles. – Luke Schultz – Coal Creek Sediment Reduction and Bank Stabilization

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.
