utførende
Utførende is a term used in Norwegian (and related Scandinavian languages) derived from the verb utføre, meaning to perform, execute, or carry out.

In many formal texts it also functions as a noun meaning the party that executes or the actor performing the work. The term is common in contracts, project plans, and administrative or regulatory documents, where responsibilities are divided between a party that orders or commissions work and the utførende.
