Lead appointed party

CurrentLAP

The party appointed directly by the appointing party that coordinates information management for its whole delivery team.

Explanation

The lead appointed party prepares the BIM execution plan, aggregates TIDPs into the Master information delivery plan, issues Exchange information requirements to its appointed parties, and checks information before it is submitted to the appointing party. A project can have several lead appointed parties, one per direct appointment (for example a separate design consultant and construction manager).

Practical example

Under a construction management contract, the construction manager is a lead appointed party for construction information, while the architect is a separate lead appointed party for design information.

Why it matters

Knowing who the lead appointed party is tells you who is accountable for the quality and timing of the delivery team's information.
