0013Q Corridor-Ashaway_DOQ Item 201.0403_Addendum-2.pdf

This is an Addendum document prepared for the Rhode Island Department of Transportation (RIDOT) relating to the Corridor-Ashaway project, a federally funded bridge replacement initiative in Providence County. The addendum addresses Item 201.0403, which specifies the removal and disposal of sidewalks across multiple locations including Potter Hill Road and Laurel Street. The total sidewalk removal is quantified at 3,570 square feet, converted to 400 square yards for bidding purposes. The project encompasses the replacement of three bridges (Bridge Nos. 005051, 005151, and 005251) with phased completion deadlines of November 10, 2027 for the Ashaway River Bridge and August 14, 2028 for the Potter Hill Bridge, with substantial completion required by October 23, 2028. Proposals were due August 28, 2026 at 1:00 p.m. EDT, submitted electronically through Ocean State Procures. Liquidated damages are assessed at $3,500 per day for phase completions and $1,950 per day for substantial completion milestones.

The project is funded through the Federal-Aid Highway program with 80 percent FHWA funding and 20 percent state funding under FAP Number STP-3334(001). All work is subject to Davis-Bacon prevailing wage requirements effective May 18, 2026, and Buy America compliance mandates requiring 55 percent domestic content for manufactured products. Contractors must provide a 5 percent bid bond and 100 percent performance bond, with required insurance including $1,000,000 general liability and workers' compensation coverage. A 0.33 percent contract administrative fee applies to the project. Lump sum item breakdowns were due within 70 days of apparent low bidder notification, and prefabricated bridge units require detailed shop drawings, welding procedures, and quality documentation with precise placement tolerances.
