Overview:  Why NEC3?

The NEC3 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. 

NEC3 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.

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.
