Request for Proposal (RFP) for Asphalt pavement repairs

Addendum # 1 ( 8-14-2024)

See attached technical specifications for Asphalt milling and overlay to be used for this project.

Bidding Questions and City’s answers:

Q: For the sanitary adjustments and CB rebuild will these be billed at the unit costs noted on price sheet including surrounding base repairs and curbing or are all associated fees to be included in the total cost of the project.

A : this is a unit price contract, the contractor’s invoice must include the work items performed for each task so if a section is replaced and it had a CB rebuilt, the section will be billed at the bid price for the square yards and the same goes for the CB. There are very few areas where a CB is rebuilt without adjacent pavement replacement.
