About this file
This is a Connecticut Department of Transportation (CTDOT) standard specification sheet for concrete sidewalk construction, related to the City of Bridgeport's Citywide Sidewalk, Curb, Apron & ADA Ramp Repair and Replacement project. The specification sheet HW-921_01, effective October 23, 2024, provides detailed technical requirements for concrete sidewalk installation, including standard dimensions of 5 feet in width with 4-foot minimum passing spaces at intervals not exceeding 200 feet. The specifications detail construction methods including concrete placement in two equal 8-inch lifts with granular fill base, expansion joint spacing of 4 to 12 feet, surface slope of 1.5 percent typical with 2 percent maximum toward the gutter, beveled edges with 1/4-inch maximum vertical surface discontinuities, and finished surfaces with wood float. Additional requirements address manhole grates with specifications for horizontal and elongated openings not exceeding 1/4-inch, curbing installation as either precast or cast-in-place, and pedestrian ramp types as detailed in accompanying CTDOT concrete sidewalk ramp guide sheets. The Bridgeport procurement seeks electronic bid submissions through the City's OpenGov e-Procurement Portal with a deadline of 2:00 pm on Tuesday, September 22, 2026, with a question submission cutoff of 5:00 pm on Tuesday, September 8, 2026.
No specific pricing terms, set-aside provisions, incumbent contractor information, funding sources, or contract award and term details are specified in the provided standard specification sheet. Bidders are required to create accounts on the OpenGov Procurement platform and monitor the portal regularly for any issued addenda or clarifications regarding the project scope and requirements.
