Contract Documents Based on the NEC3 Suite of Contracts

ISO 6707-2 defines conditions of contract as “terms that collectively describe the rights and obligations of contracting parties and the agreed procedures for the administration of their contract; or document containing conditions of contract”. A standard form of contract, or standard contract, is a contract between two parties that is published by an authoritative industry body with fixed terms and conditions which are deemed to be agreed and are not subject to further negotiation or amendment.

The NEC is a family of contracts that facilitates the implementation of sound project management principles and practices, as well as defining legal relationships. It is suitable for procuring a diverse range of engineering and construction works, services and goods, spanning major framework projects through to minor works and purchasing of goods. NEC is a division of Thomas Telford Ltd, which is a wholly owned subsidiary of the Institution of Civil Engineers (ICE), the owner and developer of the NEC.

The following publication provides guidance on the selection of a suitable contract from the NEC3 family of contracts:

Orders for framework contracts

ISO 10845-1 defines a framework agreement as an agreement between an employer and one or more contractors, the purpose of which is to establish the terms governing contracts to be awarded during a given period, in particular with regard to price and, where appropriate, the quantity envisaged. Framework agreements enable an employer to procure engineering and construction works, goods and services on an instructed basis (call-off ) over a term without any commitment to the quantum of work instructed in the absence of a fully developed scope of work . This may be achieved by issuing a package, batch or task order in terms of a contract during the term of the contract, i.e. an instruction to provide works, to supply items of goods in a batch, or work within a service within a stated period of time.
