What is NEC3 and why do we endorse it?

NEC3 is a family of contracts that help apply good project management principles and practices, and define legal relationships. NEC’s vision is to become the global leader in promoting best practice procurement of works, services and supply.

The contracts are suitable for procuring a diverse range of works, services and supply, ranging from major framework projects through to minor works and the purchase of supplies and goods. NEC3 contracts have produced major benefits for national and international projects, in terms of time, cost savings and improved quality.

The first NEC contract – known as the ‘New Engineering Contract’ – was published in 1993. It was a radical departure from existing building and engineering contracts, as it was written in plain language and designed to stimulate, rather than frustrate, good management.

In 2009, ICE's Council formally decided to solely endorse the NEC3 suite of contracts. This followed the launch of the NEC3 suite in 2005, which built on more than a decade of extensive international use of its predecessors.

Who uses NEC3 contracts?

NEC3 contracts have become public sector contracts of choice in the UK. They're used for nearly all projects procured by national and local government bodies and agencies.

This is because of their unique foundations. For example, they:

  • Stimulate good management of the relationship between the two parties to contract
  • Can be used in wide variety of commercial situations, work and locations
  • Are clear, simple and written in plain English

Over the past 20 years, NEC3 contracts have been used on a number of major projects including:

The Hong Kong government has also mandated that all projects put out for tender in 2015 will use NEC3 contracts.

ICE's Conditions of Contract

Following ICE's formal endorsement of NEC3 contracts, its council made the decision to withdraw from the ICE Conditions of Contract (CoC). ICE transferred its part ownership of this contract to the Association for Consultancy and Engineering (ACE) and the Civil Engineering Contractors Association (CECA). ICE is no longer involved in administering this form of contract.
