Concrete Reinforcement Specification for Bristol Borough CDBG Curb Ramp Program

This is a technical specification document for concrete reinforcement materials and installation procedures for the 2026 Bristol Borough CDBG Curb Ramp Program in Bucks County, Pennsylvania. The specification establishes requirements for reinforcing steel bars, wire fabric, and accessories used in cast-in-place concrete work as part of the borough's ADA/PennDOT compliant curb ramp infrastructure project. The specification mandates the use of ASTM A615 deformed billet steel bars with 60 ksi yield grade in unfinished condition and ASTM A185 welded steel wire fabric in flat sheets for reinforcement. All reinforcing steel accessories, including tie wire, chairs, bolsters, and bar supports, must meet specified standards with plastic-coated steel types required for weather-exposed concrete surfaces. Fabrication must comply with the Concrete Reinforcing Steel Institute (CRSI) Manual of Practice, and reinforcement placement, support, and security must strictly conform to design specifications without deviation from required positions, including adherence to ACI 318 code requirements for concrete cover.

Quality assurance requirements mandate that all work be performed in accordance with CRSI standards 63 and 65, ACI 301 and ACI 318 building codes, and that design be conducted under the direct supervision of a Professional Structural Engineer licensed in Pennsylvania. Contractors must provide the engineer with access to fabrication plants for inspection purposes and submit notification of shop fabrication schedules. Welders employed on the project must submit AWS qualification certificates dated within the previous 12 months. Documentation requirements include maintaining copies of applicable standards and codes on site and submitting all required certifications and inspection notifications in advance of construction activities.
