Appointed party

The appointed party term introduced in BS EN ISO 19650 it is meant to replace PAS 1192 term ‘Supplier’

Typically it means Tier 2 and below Contractors

Who can become an Appointed party?

  1. Tier 2 or below Subcontractor = task team
    • a party appointed by the lead appointed party.
    • the party that provides the information.[1]
  2. Tier 1 Main Contractor when appointed by the client, is technically an appointed party, but in the context of the ISO 19650 framework, the Tier 1 Main Contractor who is employed by the Client and who has a leading function within Project Team is referred as Lead appointed party
    • the Lead appointed party will automatically become an ‘appointor’ (employer) for the sub-contractors downstream (task teams)
  3. Supplier
    • This PAS 1192 term is now superseded by new ISO terminology Appointed party and Lead appointed party, use of the term ‘supplier’ should be avoided on ISO 119650 projects.
Hierarchical Project Team

    UK BIM Alliance responding to the inconsistency between current guidance of CIC BIM Protocol, Second Edition 2018 and ISO 19650 Framework published updated Information protocol to support BS EN ISO 19650-2 the delivery phase of assets (Framework). The publication recognized the need for the incorporation of new terms used in contract law, namely: ‘Appointor’ and ‘Appointee’. The meaning of the terms in relation to ISO 19650 Framework is shown in Table 1

Table 1- Framework terms ‘Appointor’ and ‘Appointee’ [2]

Example: the Tier 1 appointed buy the Client or Task Team sub-contractor appointed by Tier 1

To establish if a specific party is an Appointee or the Appointor, it is necessary to determine where the party sits in the supply chain. For example, the Lead Appointed Party will be the:

  • Appointee in the Tire 1 contract

i.e., Appointing Party and Lead Appointed Party, and

  • Appointor in the sub-contract

i.e., between Lead Appointed Party and Appointed Party [1]
