A Multiple Award Indefinite Delivery/Indefinite Quantity Contract (IDIQ) for engineering construction projects in Puerto Rico, United States. The IDIQ contract will require contractors to provide construction services through both the traditional design-bid-build (DBB) and design-build (DB) methods. In the traditional DBB method the Government will provide the contractor with a full design and the associated specifications, requiring the contractor to perform solely the construction services. The DB method would require the same contractor to provide both the design and construction services. In both situations the contractor will be required to provide all labor, materials, supplies, equipment, transportation, supervision, ancillary services, and other necessary items to complete the work. The work performed may include new work, additions, alterations, or maintenance and repairs to facilities or sites. The services are for construction and real property maintenance and repair.
