This is a technical design file related to the Connecticut Department of Transportation's Installation & Revision of Traffic Control Signals project across eight municipalities in District 3. The project encompasses traffic signal installation and revision work at eight signalized intersections located in Branford, Norwalk, Westport, Madison, New Haven, North Bridgeport, East Haven, and Guilford. The scope of work includes new traffic signal equipment, pedestrian signal faces with accessible push buttons, mast arm assemblies, video and radar detection systems, LED light standards, concrete and bituminous sidewalk ramps, pavement markings, crosswalks, and emergency vehicle pre-emption equipment. Additionally, the project requires removal of abandoned equipment, installation of handholes and circuit breakers, and coordination with utility companies including Eversource. Mast arm assemblies must comply with AASHTO LRFD specifications featuring drilled shaft foundations with a minimum 2-foot diameter, 4,000 PSI concrete, and #8 rebar Grade 60, with 16- to 18-foot vertical clearance requirements. Time-based coordination and wireless radio systems for signal synchronization are required at selected locations. Bids are due July 1, 2026 at 2:00 p.m. EDT, with pre-bid questions closing at 9:00 a.m. the Monday before bid opening.

All traffic signal equipment must follow CTDOT Traffic Standard Sheets and CTDOT Highway Standard Sheets, with construction specifications governed by the Connecticut Department of Transportation Standard Specifications for Roads, Bridges, Facilities and Special Provisions, Form 819 (July 2025). Connecticut DOT Signal Lab approval is required at least 45 days prior to revision. Bidders must be prequalified with CTDOT and submit a Bid Proposal Request Form for approval. A bid bond equal to 30 percent of the bid amount is required and must be submitted in PDF format to dotbid@ct.gov prior to bid opening. Bidders must acknowledge all contract addenda on the DAS State Contracting Portal, submit a Non-Collusion Statement and OPM Form 1 (Campaign Contribution Certification), and comply with DBE requirements where applicable, including submission of DBE Regular Dealer/Distributor Affirmation Forms.
