Silver Reef Mine

Utah

AVI performed all site investigations, design plans and specifications for 513 mine openings in Southern Utah.  Designs included special bat closures and handling of radioactive materials.  A one-man survey crew equipped with the Trimble GPS Total Station performed all surveying for this project.  Survey work included verification of existing aerial photo control mapping coordinates.  Location of approximately 513 mine openings (shafts, adits, subsidence, etc.).  Project area consists of approximately six (6) square miles with three (3) limestone/sandstone 200-foot vertical uplifts.  All surveying was accomplished in 16 days with an estimated cost savings of approximately $15,000 from conventional methods.  Final Construction costs are unknown.

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.
