Bituminous seal coating with wet bottom black boiler slag aggregate

The City of Sun Prairie Public Works Department in Wisconsin is soliciting bids for a bituminous seal coating project (RFB 20-PW13) involving approximately 75,265 square yards of pavement surface treatment across 25 city streets. The project requires contractors to apply CRS-2P bituminous emulsion at 0.28 gallons per square yard with wet bottom black boiler slag aggregate at 18 pounds per square yard, including comprehensive surface preparation, street sweeping, traffic control, utility protection, and pavement marking repainting. Bidders are explicitly required to conduct independent site measurements and submit bids based on their own verified square yardage calculations. The bid submission deadline is July 10, 2020, at 2:00 p.m. local time, with a public bid opening scheduled for July 15, 2020, and a contract completion date of September 21, 2020. Contractors must submit a bid bond equal to 10% of their bid amount and demonstrate compliance with federal and state OSHA requirements and prevailing wage laws. Performance and payment bonds at 100% of the contract amount are required within ten days of award.

No specific set-aside designations for disadvantaged enterprises are mentioned in the procurement documents. The City reserves the right to increase or decrease project quantities by up to 50% and to reject any or all bids. Contractors must maintain comprehensive insurance coverage, including workers' compensation, commercial general liability ($1,000,000 per occurrence), automobile liability ($1,000,000), and $5,000,000 in umbrella liability coverage. While no specific budget range is explicitly stated, the project's scope suggests a substantial municipal infrastructure investment. Contractors must commence work within fourteen days of receiving the Notice to Proceed and will be subject to liquidated damages of $500 per day for delays beyond the September 21, 2020 completion deadline.
