About this file
This is a standard details specification document from the Washington Suburban Sanitary Commission (WSSC) in Maryland, establishing miscellaneous construction and infrastructure details for water and wastewater engineering projects. The document serves as a comprehensive reference guide containing 41 detailed specifications covering trench designs, pipeline installations, safety equipment, and facility components. The specifications address multiple pipe types and sizes, including rigid pipe gravity sewers, flexible pipe systems (ductile iron and PVC), and various construction methodologies such as bore and jack tunnel installations. Key details include specifications for concrete encasement and cradle details for sewer mains, trench erosion controls, settlement monitoring indicators, and subsurface infrastructure components. The document also outlines requirements for access infrastructure, including grab bars, ladders, handrails, platform grating, chain link fencing, and guardrails for worker safety. These standard details are intended to support the broader Water and Wastewater Engineering Services Basic Ordering Agreement, which requires qualified consultants to provide comprehensive design, inspection, assessment, and emergency engineering services for WSSC's collection and distribution system assets, with responses due by May 18, 2026.
This specification document does not contain pricing terms, set-aside information, incumbent details, or funding requirements, as it functions exclusively as a technical reference guide for construction standards and design specifications. The document was issued in September 2021 and represents WSSC's established standards for miscellaneous construction details applicable to water and wastewater infrastructure projects throughout the commission's service area in Maryland. The specifications are mandatory for all contractors and consultants working on WSSC projects to ensure consistency, safety, and compliance with commission standards.
