Why NEC?

Crossrail Eastern Tunnelling Machine NEC project

The NEC suite of contracts is suitable for procuring a diverse range of works, services and supply projects, spanning major framework deals through to minor works and the purchasing of goods and services. 

NEC contracts have been uniquely designed using the following three key unique characteristics:

  • They stimulate good management of the relationship between the two parties to the contract and, hence, of the work involved in the contract.
  • They can be used in a wide variety of commercial situations, for a wide variety of types of work and in any location.
  • They are clear, simple and written in plain English using language and a structure which is straightforward and easily understood.

No other contract has had such a transformative effect on the construction industry, putting the collaboration sharing of risk and reward at the heart of modern procurement. It has revolutionised the purchasing and delivery of works, services and supply over the last two decades and looks set to continue.

Building on Decades of success

NEC3 Engineering and construction contract

“I think NEC3 is the unsung hero of the Olympic games, a bit like the spine or the heartbeat in the human body, I believe it helped deliver the project.”
Ken Owen, Commercial Director, CLM

NEC3 contracts have been used on many high profile and successful projects over the last 20 years, including London 2012, Christchurch International Airport and the Halley VI British Antarctic Survey research station. They have delivered certainty for clients in terms of project outcome as well as ensured fair and prompt remuneration for contractors and suppliers. 

Hear from two NEC3 users on their experiences of using the contracts to successfully deliver projects:

As news of these successes spread, more and more project management teams throughout the UK and abroad adopted NEC3 contracts as a result. This includes the Hong Kong government, which committed to use the NEC3 suite for all projects tendered from 2015. In 2019, they marked ten years of NEC use in Hong Kong, and NEC contracts make up a key component of their 'Construction 2.0' plans.

Starting work in 2017, NEC3 contracts were used to successfully deliver the
Lima 2019 Pan American and Parapan American Games venues in Peru, continuing to expand its global reach.

Refined and Streamlined

NEC4 - the contract suites' next evolution - was launched in 2017. The contracts were updated and streamlined to take into account consultation responses, user feedback, industry developments and emerging best practice, with improvements in flexibility, clarity and ease of administration.

A new NEC4 Design Build Operate Contract (DBO) was added to the suite, reflecting the increasing demand for contracts extending into the operational phase, as well as a consultative NEC4 Alliance Contract (ALC) for multi-party integrated teams.

The contracts continue to see increasing global popularity, with NEC4 being selected by Sydney Water for its new procurement strategy.

What our Customers Say

Open Quote We chose NEC primarily to encourage a collaborative and cooperative approach within the project team but with clear lines of responsibility and governance. The NEC suite’s widespread use throughout the UK construction market was also a key consideration over other forms of contract, ensuring familiarity throughout the supply chain. Close Quote
