Surveying is a critical early step for residential construction and land development.

Get the job done right the first time with W.H. Smith. WHS has been in business since 1967, providing the highest level of professional land surveying services to a broad range of industries. Construction, land development and real estate professionals all agree, no other surveying company tops WHS when it comes to service. Our highly trained and professional staff is ready to take on your project. Our goal is to complete your project in the most cost-effective and timely manner possible.



WHS is proud to have one of the most experienced teams of surveyors and draftsmen in the industry. Our staff is based out of offices in Green River, Lander & Rock Springs, Wyoming; Grand Junction & Loveland, Colorado; and Dickinson, North Dakota. WHS makes sure our staff gets the very best training available in technologies such as AutoCAD and GPS. We also give our staff opportunities to attend continuing education.


Our survey equipment includes Trimble GPS scanners, robotic total stations and digital levels. We also use state-of-the-art software, including AutoCAD Civil 3D with Carlson Civil, and GIS, a system for storing, retrieving, mapping and analyzing geographic data.

Upon completion of extensive worksite surveying, WHS stakes out reference points and markers to guide new construction, verify structural location during construction and conduct an as-built survey – finishing the project to plan specifications.

In cases where preparation for immediate or future sale or development of land is necessary. WHS will conduct a thorough survey to prepare the appropriate plats needed.

When your project requires a boundary survey WHS will prepare them to standards jointly required by the American Land Title Association (ALTA) and the American Congress on Surveying and Mapping (ACSM). These surveys show improvements, easements, rights-of-way, and other elements that affect land ownership. These surveys also provide the title company with information to insure the title to the land. During project completion, areas of ownership, improvements and encumbrances are shown graphically.

Control surveys are used to adjust and verify the accuracy of project-specific surveys. We verify all project surveys against control surveys with horizontal control up through First Order by triangulation, trilateration, traverse or a combination of these techniques and vertical control through Second Order Class I.

Topographical surveys involve recording the terrain, mapping the three-dimensional quality of the surface, and identifying specific landforms. We use aerial photogrammetry, LiDAR, and grid system methods as well as GPS to produce the data for highly accurate topographic maps.

Because a quality survey is only as good as the plats and other documentation needed to obtain permits and work orders, drafting is central to our client services. We offer a quick turnaround and make sure that what we deliver is easy to read and follow. WHS handles all types of drafting, including well location plat packets, pipeline alignment drawings, road designs, ALTA surveys, property boundary surveys, topographic surveys, SWPP and BMP drawings, subdivisions, as-built or Record of Survey drawings, etc.


Established in 1967 as William H. Smith and Associates, now known by our clients and industry as WHS, has become an Engineering and Land Surveying company existing firmly on our accountability, professionalism and expertise standing alongside and supporting our clients and the communities where we live and work.
