About this file
This is a technical specification document for concrete reinforcement in support of the Canterbury Storm Sewer Replacement contract with Montgomery Township, Pennsylvania. The project involves removal and replacement of approximately 1,800 feet of storm sewer piping ranging from 12 inches to 57 inches by 38 inches, construction of new circular HDPE pipe and elliptical RCP storm sewer, replacement of three precast concrete storm sewer structures, and restoration of concrete curb, sidewalk, driveway apron, and asphalt roadway on Canterbury Lane and Devonshire Drive. Sealed bids are due online via the PennBid Program by 10:00 A.M. on September 1, 2026, with public opening and reading at Montgomery Township offices located at 1001 Stump Road, Montgomeryville, PA 18936. No pre-bid meeting will be held for this project.
The specification document establishes the requirements for reinforcing steel bars and wire fabric to be used in cast-in-place concrete, mandating compliance with ASTM A615 deformed billet steel bars at 60 ksi yield grade and ASTM A185 welded steel wire fabric. All work must be performed in accordance with CRSI standards, ACI 301 and ACI 318 codes, with design supervised by a Professional Structural Engineer licensed in Pennsylvania. Bid security of not less than ten percent of the bid amount is required, with Performance and Payment Bonds mandated. The project is subject to the Pennsylvania Prevailing Wage Act and Act 127 Public Works Employment Verification requirements. A nominal PennBid fee of 0.33 percent of the bid amount applies to awarded bidders, with a minimum of $150 and maximum of $6,000.
