Attachment 1 Backflow Scope of Work.pdf

The document is a detailed Scope of Work for Backflow Assembly Repairs for the City of Dearborn, Michigan, covering multiple facilities across the city. The scope outlines 27 specific work assignments at various locations, including power houses, administrative centers, fire stations, libraries, recreation centers, sewage facilities, and other municipal buildings. Each work scope involves isolating existing backflow preventers (RPDA, RPBP, PVB), tearing down and rebuilding assemblies according to manufacturer specifications, flushing and cleaning interior assemblies, and testing and recertifying the devices. The repairs target different types of water systems including fire protection, lawn irrigation, boiler feeds, and domestic water lines.

The document does not include specific pricing details or funding sources. Each work scope is marked with a specific location, device type, and size, and all test forms indicate a failed inspection status, suggesting these repairs are part of a mandatory maintenance and compliance program. The testing was conducted by Guardian Plumbing & Heating, with all inspections performed by Ken Johnson using a MIDWEST gauge. The initial test dates range from December 2nd to December 10th, 2024, with all devices requiring recertification and repair to meet municipal water system standards. The comprehensive scope suggests a systematic approach to maintaining critical water infrastructure across the city's facilities.
