23 C.F.R. § 635.602
As used in this subpart:
Best value selection means any selection process in which proposals contain both price and qualitative components and award of the contract is based upon a combination of price and qualitative considerations. Qualitative considerations may include past performance, timeliness, reliability, experience, work quality, safety, or other considerations.
Contracting agency means the State department of transportation (State DOT), and any State or local government agency, public-private partnership, or Indian tribe (as defined in 2 CFR part 200) that is the acting under the supervision of the State DOT and is awarding and administering an Indefinite Delivery/Indefinite Quantity (ID/IQ) contract.
ID/IQ means a method of contracting that allows 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.
ID/IQ contract means the principal contract between the contracting agency and the contractor. Contracting agencies may use other names for ID/IQ contracts including job order contracting (JOC) contracts, master contracts, on-call contracts, push-button contracts, design-build ID/IQ contracts, design-build push button contracts, stand-by contracts, or task order contracts.
JOC, or Job order contracting, means 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.
JOC contract means a type of ID/IQ contract delivered using the JOC method. Requirements for ID/IQ contracts apply to JOC contracts unless otherwise specified in this subpart.
NEPA process has the same meaning as defined in § 635.502 of this part.
Unit price book means a book, guide, list, or similar document which includes defined construction tasks, and for each task, includes a unit of measure and a preset unit price.
Work order means the contract document issued for a definite scope of work under an ID/IQ contract. It defines the location, time, and scope of work required by the contracting agency. It also defines required pay items, quantities, and unit prices, as applicable. Contracting agencies may use other names for work orders including job orders, service orders, task orders, or task work orders.
