How NEC3 Works

NEC in action

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.


Works

Works encompasses purchases such as the construction, refurbishment and decommissioning of buildings, structures, process plants and infrastructure – including everything from houses, schools, hospitals and leisure facilities to infrastructure for water, energy, transport, industry and waste.

Services

Services includes purchases of professional services such as engineering, architectural, project management and consultancy works. It also covers composite services such as facilities management, cleaning, catering, security, maintenance and data processing.

Supply

Supply includes supply of high-value goods and associated services such as transformers, generators, rolling stock, cranes, gantries and complex plant. It also includes lower-risk items such as building materials and products, stationery, personal protective equipment and parts.
