The United States Postal Service is seeking proposals for a Job Ordering Agreement Contract (JOC) for the repair and alteration of USPS-owned or leased buildings in Illinois. This indefinite delivery, indefinite quantity contract will use a Construction Task Catalog with pre-set unit prices, to which bidders propose Adjustment Factors. Work will be issued through individual work orders, each with a firm fixed price, after joint scope meetings and detailed proposals. Performance of services will take place at various USPS facilities across the State of Illinois. No specific budget amount or submission timeline is provided in the description.
