The contract will be awarded to the lowest responsive and responsible bidder based on a lump sum bid. Key requirements include a 20% Disadvantaged Business Enterprise goal and a 5% bid bond. Performance milestones are set at 730 calendar days for substantial completion and 820 calendar days for final completion, with liquidated damages of 6,120 dollars and 1,700 dollars per day, respectively, for delays beyond these dates. The project includes a total not-to-exceed allowance of 30,000 dollars for permitting and temporary easements. Contractors must maintain a rigorous quality control system, including a dedicated Quality Manager and detailed daily logs, to ensure all work meets Metra's specifications.
