Donnell & Allred, Inc. has been providing accurate and competitive land surveying in the Big Horn Basin for over 80 years. Sherman Allred, P.E. & L.S., has been a licensed Professional Land Surveyor since 1979. With his vast experience in the surveying field he is able to provide timely, efficient and accurate land surveys for our clients. One of our projects was a utility location survey for TSP, Inc. Erik Miller of TSP remarked "I have to let you know that [this] is probably the best utility survey I've ever seen. The number of shots you guys took, and the level of detail in your notes is awesome." We also have completed hundreds of property, topographic and boundary surveys in Worland, Ten Sleep, Basin and the surrounding areas.
Our state of the art survey and computer equipment provides our clients with the best product, and in much less time than it would have taken just a few years ago. We have a complete Leica survey grade GPS system to allow a one-man crew to quickly survey with sub-centimeter accuracy and a Leica survey grade digital level for precise elevation measurements. We also have a Nikon total station for traditional surveying in areas where GPS is impractical or inefficient. This instrument can take shots over a mile long in under five seconds with accuracy to less than a quarter of an inch.
Donnell & Allred has the expertise, experience and tools necessary to provide our clients with a timely and cost effective subdivision plat. We have licensed engineers on staff to provide any necessary design for water and sewer as well as manage the permitting processes required. We utilize AutoCAD Civil 3D, a very powerful and comprehensive software package, for designing infrastructure. We also use PCSurvey for surveying analysis and design. We save our client costs by using these software programs to take a subdivision from survey data to a finished, filed plat quickly and efficiently.
