Addendum_No._2_City_Standard_Detail_W-5.pdf

This is an addendum document issued by the City of Bradenton, Florida, Department of Engineering and Public Works and Utilities for the Ironwood Water Main Replacement Project. Addendum No. 2 establishes technical specifications for PVC pipe thrust restraint requirements at fittings, valves, and joints throughout the water distribution system. The addendum specifies that EBBA Iron Megalug restrainers must be used at fittings and valves, while EBBA Iron Series 1500 restrainers are required between pipe joints, with all calculations based on 30 inches of cover depth. Critical components requiring complete restraint include bends at inlet and outlet locations, tees, offsets at inlet and outlet locations, caps, plugs, and entire hydrant runouts in all applications.

This addendum clarifies mandatory restraint specifications to ensure structural integrity and prevent pipe movement in the approximately 5,180 linear feet of water main construction involving various pipe sizes and configurations. By establishing these standardized restraint requirements upfront, the City ensures that all bidders understand the technical requirements and can provide accurate pricing for the specialized materials and installation methods necessary to meet the water distribution system's performance standards.
