About this file
This is a technical specification document for concrete reinforcement work prepared by the Municipal Authority of the Borough of Morrisville, Pennsylvania, in connection with their 2026 Design/Build Curb Ramp Project. The specification details requirements for reinforcing steel bars, wire fabric, and accessories used in cast-in-place concrete construction. Materials specified include ASTM A615 deformed billet steel bars with 60 ksi yield grade in unfinished condition, ASTM A185 welded steel wire fabric in plain type and flat sheets, 16 gauge annealed epoxy-coated tie wire, and plastic-coated steel chairs, bolsters, bar supports, and spacers for weather-exposed concrete surfaces. Work must be performed in accordance with standards established by the Concrete Reinforcing Steel Institute (CRSI), American Concrete Institute (ACI), and American Society for Testing and Materials (ASTM), with reinforcement design supervised by a licensed Professional Structural Engineer in Pennsylvania. Contractors must submit welder certifications verifying AWS qualification within the preceding twelve months and provide engineers access to fabrication plants for inspection during shop fabrication.
The specification establishes rigorous quality assurance requirements including maintenance of applicable code documents on-site and compliance with CRSI Recommended Practices for placing reinforcing bars and bar supports. Reinforcement must be placed, supported, and secured to prevent displacement while maintaining required concrete cover per ACI 318 code, and reinforcing splices must be located at points of minimum stress per CRSI Manual of Practice. Fabrication must accommodate formed openings and protect vapor barriers during placement, with all work conforming to applicable Pennsylvania building codes. No specific pricing, set-asides, or incumbent information is detailed in this technical specification document.
