About this file
This is a standard engineering specification sheet issued by the Connecticut Department of Transportation (CTDOT) Office of Engineering in Newington, Connecticut, depicting detailed construction standards for concrete driveway ramps. The document, designated as Standard Sheet HW-924_01 and dated November 25, 2024, provides comprehensive technical guidelines for the design and construction of driveway ramps in residential and commercial applications. The specifications include multiple plan and section views (Plans A, B, and C) that illustrate ramp configurations with specific dimensional requirements, including maximum grade specifications of 8 percent for commercial applications and 12 percent for residential applications. Key construction details include 8-inch concrete thickness with 2-inch bituminous concrete overlay, 6-inch granular fill base, minimum 4x4 W6.5x W6.5 welded steel wire fabric reinforcement, and variable ramp configurations with pedestrian sidewalk setbacks. The sheet was submitted by Leo Fontaine, P.E., and approved by Michael N. Calabrese, P.E., on January 29, 2025, indicating current regulatory applicability for projects within Connecticut jurisdictions.
This standard specification sheet serves as a reference document for the City of Bridgeport's Citywide Sidewalk, Curb, Apron & ADA Ramp Repair and Replacement project, for which electronic bids are being received through the City's OpenGov Procurement Portal until 2:00 p.m. on September 22, 2026. The technical guidelines establish minimum construction standards and material specifications that bidders must comply with when submitting proposals for sidewalk, curb, and ADA ramp work throughout Bridgeport. All bidders are required to review addenda posted on the procurement portal, with the deadline for written questions set at 5:00 p.m. on September 8, 2026, ensuring bidders have access to clarifications regarding these engineering standards prior to proposal submission.
