What kind of work

25 projects involve bridges, from culvert replacements under I-84 in Southbury to deck repairs on groups of bridges in each CTDOT district and the rehabilitation of the Bulkeley and Founders bridges in Hartford. Seven are pavement preservation contracts, including asphalt rubber chip seals, thin friction wearing courses and an ultra-thin bonded overlay on I-84. 13 are rail and transit projects, including New Haven Line power upgrades, station improvements and bus facilities. Others cover traffic signals, illumination, intersections, sidewalks and a trail.

21 projects are listed by CTDOT district rather than by town; they bundle work at many locations, such as pavement preservation, sign and signal replacements and bridge coating.

Where

Counting each town-based project once for each county it touches, using the county a town historically belonged to, Hartford County has the most with 20, followed by New Haven with 14, New London with 7 and Fairfield with 4.

What it means

An advertising date is when CTDOT plans to post the project for bids, not the bid date. CTDOT calls the list tentative, updates it monthly and says actual advertising and bid opening dates are on the DAS CTsource Bid Board. But the list gives contractors months of notice. Prime contractors must be prequalified by CTDOT and must file a Bid Proposal Request Form (Part C) for each project they want to bid. Subcontractors do not need CTDOT prequalification, so the schedule is a guide for subs to start talking to primes in the right work classes.
