Final answer:
The three types of Indefinite Delivery Contracts are Indefinite Delivery, Indefinite Quantity Contracts, Delivery Order Contracts, and Task Order Contracts. Each type provides a mechanism for the government to order supplies or services over a period of time without specifying the exact quantity at the time of the contract award.
Step-by-step explanation:
There are three types of Indefinite Delivery Contracts: Indefinite Delivery, Indefinite Quantity (IDIQ) Contracts, Delivery Order Contracts, and Task Order Contracts.
An IDIQ Contract provides for an indefinite quantity of supplies or services during a fixed period. The government places orders for individual requirements. Quantity limits may be stated as number of units or as dollar values.
Delivery Order Contracts are used when the exact times and/or quantities of future deliveries are not known at the time of contract award. They allow for the issuance of orders for the delivery of supplies during the term of the contract.
Task Order Contracts are similar to delivery order contracts but are used for service contracts rather than goods. The government issues task orders for services that are to be performed within the stipulated terms and conditions of the contract.
