Amendment of a contract is necessary when there is a need to change the material aspects of the contract, such as extension of the duration of the contract, or modification of the goods or services to be delivered. Amendment of contract for price is a delicate issue as the revised price may have affected the selection of the vendor. Regular price revision for standard products (fuel, food, supplies, etc.) may be included in the original contract to prevent recurrent one time negotiation.

Guidelines for Making Amendments to a Contract
	Amendments to a contract, if required, shall be numbered serially, commencing with Amendment No. 1. Each amendment shall identify the contract to which it refers by number, subject and date. The nature of the amendment shall be clearly described and include a statement that all other terms and conditions of the contract shall remain unchanged. The procedures for signing an amendment are the same as those for the original contract. Amendments shall be submitted to the HCC/LCC, in accordance with the Delegation of Authority as spelled out in the Procurement Manual Chapter 3.
