NEC4 Contract

The range of new and existing specialist contracts within the NEC4 contract family includes:

Design, Build and Operate Contract

Dispute Resolution Contract

Framework Contract

Managing Reality Guide Books

Professional Services Contract

Supply Contract

Term Service Contract

The NEC4 is suitable for procuring a full array of Works, Services and Supply, ranging from a major framework to small-scale projects.


Two brand new contracts have been added to the suite - NEC4 Design, Build and Operate Contract (DBO) and NEC4 Alliance Contract (ALC).
The NEC4 is an evolution on the successful NEC3. NEC4 contracts keep on using plain English and present tense to facilitate the celebration of contracts across the world.

NEC4: changes and improvements


NEC4 Design, Build and Operate Contract:
Combines responsibility for usually disparate functions - design, construction, operation or maintenance to support operational requirements procured from a single supplier.
NEC4 Alliance Contract: For all parties to work together in achieving Client objectives, and share in the risks and benefits of doing so.
BIM Option: To support the use of Information Modelling. It provides additional clauses to support the management of Information Model Requirements. The NEC4 BIM Option deals with issues of Information Model and information ownership, and liability of the parties.
Contractor's design and build option: Contractor's design duty has been aligned with industry standard for designers.
Early Contractor Involvement (ECI): Launched separately from the contracts in 2015, the ECI is now part of the NEC4 ECC.
Dispute Avoidance Board: To encourage and support parties in resolving any dispute or difference consensually.
Payment provisions improved: Periodic assessments now require an application by the Contractor. If no application is made by the assessment date, the Contractor does not receive payment.
New guidance suite: In producing NEC4 contracts the guidance documents were completely reviewed and re-structured.

NEC4: Guidance Notes & Flow Charts

The guidance notes for all NEC4 contracts have been updated and consolidated. They are provided into four distinct volumes, dealing with procurement strategy, contract preparation, supplier selection and contract management.
