[cited from ISO 19650-1:2018(en), 3.2.5]

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

Table 1-Framework terms’ Appointor ‘and’ Appointee’

Framework TermISO 19650 Termmeaning
AppointorAppointing Partythe party carrying out the appointment for this contract/appointment

The client appoints the Lead Appointed Party

Appointing party term introduced in BS EN ISO 19650 it is meant to replace PAS 1192 term ‘Employer’

Who is an Appointing party?

  1. A Client who appoints Tier 1 Main Contractor
  2. A party who is managing information on behalf of the client.[1]

Technically speaking an Appointing party would be also a Tier 1 Main Contractor if he employs other sub-contractors, but in such a situation ‘appointor’ would be a more suitable description. In the context of the ISO 19650 framework, the Tier 1 Main Contractor who employs other subcontractors should only be regarded as Appointing party if such Tier 1 Main Contractor is managing information on behalf of the client.[1]

Typically the Tier 1 Main Contractor will have a leading function named the Lead appointed party when appointed by the Client

Where an ISO 55001 asset management system is in place, “appointing party” is synonymous with the term “organization” in ISO 55001.
