Silver Reef Mine


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.

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

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

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.
