Inspection and Engineering Support Services for Tunnels

The District of Columbia Office of Contracting and Procurement (OCP), acting on behalf of the District Department of Transportation (DDOT), is seeking a contractor to provide comprehensive inspection and engineering support services for tunnel infrastructure through contract DCKA-2025-Q-0080. The primary objective is to obtain technical and management support for DDOT's tunnel management team, with a focus on detailed investigative services spanning structural, civil, mechanical, electrical, lighting, fire/life safety, security systems, and signage assessments. Contractors will be required to conduct thorough tunnel asset inspections, identify systemic deficiencies, determine root causes of infrastructure issues, and develop comprehensive design and corrective solutions. The scope of work mandates proposing appropriate repair and retrofit measures for deficient tunnel assets, demonstrating advanced engineering and diagnostic capabilities. The solicitation was posted on November 3, 2025, with proposals due by December 4, 2025, providing potential bidders approximately one month to prepare and submit comprehensive technical and management proposals.

While specific set-aside designations or disadvantaged enterprise requirements are not explicitly detailed in the provided documentation, the contract appears to be a specialized technical procurement requiring significant engineering expertise. Potential bidders should possess advanced technical capabilities in tunnel infrastructure assessment, diagnostic analysis, and remediation strategy development. The contract suggests a need for multidisciplinary engineering competencies, including structural engineering, mechanical systems expertise, electrical infrastructure knowledge, and safety system evaluation skills. Although specific budget ranges are not disclosed, the complexity of the work implies a substantial contract value commensurate with the comprehensive technical services required. Interested contractors should carefully review the full solicitation documents to understand the complete scope of requirements, submission protocols, and potential integration expectations with existing DDOT tunnel management infrastructure and technological systems.
