This Test Pit Report is a technical document prepared for the Washington Suburban Sanitary Commission (WSSC) in support of the Large Valve Vault Replacement project in the Silver Spring area of Montgomery County, Maryland. The project involves the replacement of approximately 87 feet of 30-inch water main, 48 feet of 72-inch water main, and one 30-inch valve and vault. Sealed responses for this project are due via WSSC's eProcurement Portal at https://procurement.opengov.com/portal/wsscwater prior to 2:00 pm on Wednesday, July 22, 2026, with late responses not being accepted. The Test Pit Report serves as supporting documentation to inform bidders of subsurface conditions and existing infrastructure at the project site, enabling them to develop accurate proposals and construction methodologies.

The Test Pit Report provides critical subsurface investigation data necessary for bidders to assess site conditions, identify potential conflicts with existing utilities, and plan appropriate excavation and replacement procedures. This technical exhibit allows contractors to evaluate ground composition, water table levels, and the condition of existing infrastructure encountered during the investigation, thereby reducing construction risk and supporting accurate cost estimating. The report is essential supporting documentation for the solicitation and helps ensure that bidders have adequate information to submit competitive and feasible proposals for this water main and valve vault replacement project.
