New Engineering Contract

NEC was first published in 1993 as the New Engineering Contract. It is a suite of construction contracts intended to promote partnering and collaboration between the contractor and client. It was developed as a reaction to other more traditional forms of construction contract which have been portrayed by some as adversarial.

The intentions of NEC contracts include:

• Stimulating good management.
• Being clear and simple, written in plain English, in the present tense and without legal terminology.
• Being useable in wide variety of situations from minor works to major projects
