The NEC3 Supply Contract (SC) is the first set of standardised terms designed for local and international procurement of high-value goods and related services including design. This new addition to the NEC3 family is designed around the same model as other NEC documents yet is flexible enough to apply to any industry or supply situation. Construction Clients' Board endorsement of NEC3 The Construction Clients' Board (formerly Public Sector Clients' Forum) recommends that public sector organisations use the NEC3 contracts when procuring construction. Standardising use of this comprehensive suite of contracts should help to deliver efficiencies across the public sector and promote behaviours in line with the principles of Achieving Excellence in Construction.
