The consulting firm of R. F. Sayre & Associates was formed January 1, 1969, in Sioux Falls, by Richard F. Sayre. Over the years, the company has grown in size and engineering capabilities, but our values have never changed.

We are a full-service civil engineering firm with a full-time staff of 22, including 10 registered engineers and two land surveyors. We provide planning services, topographic surveying, engineering design, construction surveying and construction administration services. We also have expertise in transportation engineering, drainage, erosion control, wetland delineation and mitigation.

Our survey crews utilize the latest technology in survey equipment with Trimble S6 robotic total station and Trimble R8 and R10 GPS systems.  Our survey personnel are educated and experienced in the use of the equipment and exhibit a high degree of professionalism dealing with clients and contractors.

The technical staff of Sayre Associates has extensive knowledge and experience in site design, street construction and surveying practices. Our technical staff is directly involved in projects from day one to completion and offer valuable insight, project input and objective viewpoints for every project.

Sayre Associates is proud of our history and our current staff. We look forward to a promising future serving our clients with the same high standards the firm is founded upon.
