What Sayre Associates does
Sayre Associates, Inc. is a privately held civil engineering and land surveying firm founded in 1969 and headquartered at 216 S. Duluth Avenue in Sioux Falls, South Dakota. The firm operates in South Dakota, Minnesota, and Iowa, with the majority of its land surveying work conducted within a 60-mile radius of Sioux Falls. Its service portfolio spans Municipal and Transportation Engineering, Site Design, Land Development Planning and Engineering, Professional Land Surveying (including ALTA/NSPS, boundary, topographic, mortgage, and flood elevation surveys), Schools/Parks/Recreation Facilities design, Construction Phase Services, Vibration Monitoring, and Wetland Delineation and Mitigation. The firm is the only South Dakota-based company offering vibration monitoring services for construction and blasting activities, conducted using seismographs (Instantel Micromate units) for pre-existing condition surveys, crack monitoring, and remote monitoring. Staff includes engineers, surveyors, CAD technicians, landscape designers, and administrative personnel; 21 Professional Engineers have contributed over the firm's history with 11 current PEs.
The firm's underlying technical toolset combines mainstream civil engineering and surveying platforms — AutoCAD Civil 3D, Eagle Point software, Microstation, 3D scanning, drone surveying, and seismograph-based vibration monitoring — with human-delivered professional services from initial site assessment and surveying through design, permitting, and construction administration. Its core differentiated offerings are the unique vibration monitoring capability and integrated surveying-to-construction-administration workflow across the tri-state region.
Sayre Associates generates revenue through project-based professional services contracts with both public and private sector clients. Its go-to-market is relationship-driven and direct: the firm engages municipal governments (e.g., City of Freeman, Sioux Falls Convention Center), educational institutions (e.g., Jefferson High School), and commercial/industrial clients (e.g., Amazon facility in Foundation Park) via phone, email, website inquiries, and in-person consultation, with no resellers or intermediaries. Marketing is conducted through the company website, social media (Facebook, LinkedIn, Yelp), and industry conference exhibitions such as ASBSD and SASD. There is no disclosed external funding, no parent company, and no subsidiaries; ownership is private with long-tenured personnel continuity.
