Overview of roles, duties and liabilities of construction consultants, including lead consultant and Principal Designer responsibilities under the CDM Regulations and the Building Regulations, and key case law

Construction projects frequently rely on a wide range of professional consultants, each undertaking distinct responsibilities. The size of the team varies with the project’s scale, and who makes the appointments will depend on the procurement route. Nevertheless, the principal consultants are broadly consistent across most schemes. This Practice Note outlines the roles of those key consultants and draws attention to their main duties. For a summary of the roles of the parties commonly involved in a construction project (including consultants as well as the employer, contractor and sub-contractor), see Practice Note: Parties in a construction project. For a visual of the contractual framework typical of a construction project, and how consultants are positioned within it, see: Structure of a development project—diagram.
