NEC produces a diverse range of definitive end-to-end project management contracts that empower users to deliver projects:
- on time
- on budget
- to the highest standards.
The suite is uniquely flexible and can be used for the procurement of works, services and goods across all sectors – including public and private, buildings and infrastructure, plant and equipment – as well as all stages of a project lifecycle, from planning, design and project management to construction, maintenance and facilities management.
Each contract is supported by associated guidance notes and flow charts, detailing exactly what procedures should be followed by whom and when.
The NEC structure
The principal NEC3 contracts, short contracts and subcontracts can be broadly grouped into works, services and supply as shown below. The choice of NEC3 form depends on the project complexity and level of risk.
There are some innovative new features and new contracts in NEC4 suite which will help users achieve further improvements to the efficiency and outcome of their projects and work programmes.
New forms of contract
NEC4 Design Build Operate Contract (DBO) allows Clients to procure a more integrated whole-life delivery solution.
The Alliance Contract (ALC) suits Clients who wish to enter into a single collaborative contact with a number of participants in order to deliver a project or programme of time.
The guidance notes for NEC4 contracts have been updated and consolidated. They are provided in four distinct volumes, dealing with procurement strategy, contract preparation, supplier selection and contract management. The contract preparation and contract management volumes sub-divide into separate books for each NEC contract.
