Utility Locating and Subsurface Mapping Services

The contract encompasses the provision of underground utility locating and subsurface mapping services within the highway rights-of-way managed by the South Dakota Department of Transportation. Contractors are required to perform accurate identification and physical marking of subsurface utilities using SD811 requests as the primary coordination mechanism, ensuring compliance with state safety and procedural standards. All activities must be thoroughly documented to provide verifiable records of utility locations, with an emphasis on precision and timeliness to support highway construction, maintenance, and safety initiatives across the state. The work is regionwide in scope and must be executed in accordance with industry best practices for non-destructive detection methods and subsurface utility engineering. The procurement is issued as a subcontract under NAICS code 541370, which classifies the services as engineering and related technical activities. The solicitation was posted on June 16, 2026, with an identical deadline, indicating that the award is likely based on pre-qualified vendors or an administrative process rather than a competitive public bid. Performance is expected throughout South Dakota’s highway network, with the primary oversight and operational direction coming from the South Dakota Department of Transportation. No specific set-aside provisions or geographic restrictions are indicated, and all work must remain coordinated under the agency’s established protocols for utility coordination and right-of-way management.
