This procurement is for a multiple award construction contract (MACC) and is being advertised on an unrestricted basis inviting full and open competition. This procurement uses the two-phase design-build selection procedures and consists of one solicitation covering both phases with the intent to award approximately eight (8) or more Indefinite Delivery Indefinite Quantity (IDIQ) construction contracts to the responsible offerors whose proposals, conforming to the Request for Proposal (RFP), will be most advantageous to the Government resulting in the best value, price and other factors considered. Price evaluation preference will be given to HUBZone Small Business concerns, in accordance with FAR 52.219-4. This is an IDIQ contract with no pre-established fixed contract prices. The actual amount of work to be performed and the time of such performance will be determined by the Contracting Officer or properly authorized representative, who will issue written task orders to the contractor. Award of task orders will be on a firm fixed price basis. The work to be acquired under this solicitation is for new construction, renovation, and/or repair, by design-build or design-bid-build, of commercial and institutional facilities at various Government installations located in California, Arizona, Nevada, Utah, Colorado, and New Mexico. However, it is anticipated that the majority of the work will be performed in California. Types of projects may include, but are not limited to: airport buildings, office/administrative buildings, communications facilities, vehicle maintenance facilities, armories, parking garages, barracks facilities, prison facilities, fire stations, religious buildings, hotels, dining facilities, hospital/medical facilities, warehouse facilities, school facilities, and/or retail facilities.
