Appointing party

Terminology status: Current

Also: Client, Owner, Employer (historical)

Quick definition: The party that receives information about works, goods or services from a lead appointed party — usually the owner or client.

Explanation

Technical explanation

ISO 19650 uses role-based terms instead of contract titles so that the process applies to any procurement route. The appointing party sets the Exchange information requirements, establishes the project's information standard and Common data environment (or delegates this), and accepts or rejects information deliveries. The appointing party may appoint a third party to carry out information-management functions on its behalf, but it retains accountability.

Practical example

A city that hires a design-build team for a new fire hall is the appointing party; the design-builder is the lead appointed party.

Why it matters

Using role terms avoids confusion when the same company plays different roles on different contracts.

Historical context

Earlier UK documents used "employer"; ISO 19650 replaced it with appointing party.
