Indefinite Delivery/Indefinite Quantity Contracting for Federal-aid Construction (Including Job Order Contracting)

The Indefinite Delivery and Indefinite Quantity (ID/IQ) project delivery method allows an owner to procure an indefinite quantity of services for a fixed time. This method is used when a contracting agency anticipates a recurring need but has not determined, above a specified minimum, the precise quantities of services that it will require during the contract period. Contractors bid unit prices for estimated quantities of standard work items, and work orders are used to define the location and quantities for specific work. Job order contracting (JOC) is a form of ID/IQ contracting that uses a unit price book in the solicitation and the bidder's adjustment factors or multipliers to establish contract prices.

On November 16, 2020, FHWA published the ID/IQ Contracts for Federal-aid Construction Interim Final Rule and request for comments. This action allows States to use the ID/IQ method of contracting, including JOC, on Federal-aid highway projects, under certain circumstances, on a permanent basis. The Interim Final Rule also establishes a 12-month transition period for ID/IQ projects delivered under the Special Experimental Project Number 14 (SEP-14) authority of 23 U.S.C. 502(b)(2) and FHWA Notice N 5060.2. Per the Interim Final Rule, the Notice will expire on November 16, 2021.

The Interim Final Rule is effective upon publication. Public comments will be received and may be viewed online through the Federal eRulemaking portal at: www.regulations.gov/.
