The United States Postal Service is soliciting proposals for a roof replacement project at its facility in Charleston, South Carolina. The estimated cost for the work is between $4,000,000 and $5,000,000, with a required construction completion timeline of no more than 180 calendar days after a Notice to Proceed. The Postal Service will award the contract based on best value, prioritizing the lowest overall price while considering superior technical or management features that may merit a higher cost. Key requirements include demonstrating experience with two comparable projects, the ability to obtain full performance and payment bonds, and the submission of specific plans before work begins. All proposals must be submitted electronically via the USPS eSourcing Coupa platform.
