102_ATS_-_TM_-_Condition_Assessment.pdf

This is a Condition Assessment document prepared for the Washington Suburban Sanitary Commission (WSSC) in Maryland, supporting the 102-Inch Anacostia Trunk Sewer (ATS) Rehabilitation Phase 2 Progressive Design-Build project located in Lower Anacostia, Prince George's County. The document provides a comprehensive technical evaluation of the existing 102-inch diameter trunk sewer infrastructure, detailing the current structural and operational condition of the sewer system to inform the design and construction phases of the rehabilitation project. The assessment establishes the baseline conditions necessary for qualified respondents to develop proposals for the progressive design-build services, with sealed responses required to be submitted via WSSC's eProcurement Portal at https://procurement.opengov.com/portal/wsscwater no later than 2:00 pm on Tuesday, June 23, 2026.

The condition assessment serves as a critical supporting exhibit for the solicitation, providing detailed technical data on pipeline deterioration, structural integrity, capacity constraints, and other factors relevant to rehabilitation planning. This information enables design-builders to accurately scope work, identify rehabilitation methodologies, and prepare cost estimates for the project. The document forms part of the contract package materials that qualified firms, design-builders, or Progressive Design-Build teams must review to develop comprehensive and competitive proposals for the rehabilitation of this major sanitary infrastructure asset.
