EPC, split EPC and multi-party contract projects

The following Construction guidance note Produced in partnership with Clarke Willmott LLP provides comprehensive and up to date legal information covering:

  • EPC, split EPC and multi-party contract projects
  • EPC contract procurement
  • Split EPC contract procurement
  • Multi-party contract procurement

There are three main procurement routes used in UK energy projects:

  1. engineering, procurement and construction (EPC) contract procurement

  2. split EPC contract procurement

  3. multi-party contract procurement

This Practice Note provides a review of each of these methods, and discusses some of the benefits and disadvantages of each route and practical issues to consider. It is intended as a basic guide; professional legal advice should be sought before choosing a procurement option for your specific project.

For more information on EPC contracts see Practice Notes: Introduction to EPC contracts, EPC contracts—handover, testing and commissioning and EPC contracts—limits of liability.

The diagram below illustrates the key contractual structure of a project procured using the EPC route with project finance backing. This structure may change from project to project although the diagram details the contractual matrix:
