Information Delivery Cycle

term introduced first in PAS 1192 and updated in ISO 19650 framework, it depicts the process of specifying and delivery of project and asset information

Digital Plan Of Work (DPoW)

forms a framework that supports informed and consistent decision making by project teams, at each work stage, helping to deliver agreed and reliable information.

Exchange Information Requirements (EIR)

Exchange Information Requirements (EIR) term introduced by BS EN 19650 replace the PAS 1192 term Employer Information Requirements (EIR) on all projects where BS EN ISO 19650 compliance is required.

Lead Appointed Party

The term introduced by ISO 19650 typically describes the Tier 1 Main Contractor.

Federation Strategy

breakdown structure to help plan the production of information

Task Information Delivery Plan (TIDP)

schedule of information containers and delivery dates, for a specific task team

Model Production Delivery Table (MPDT)

An MPDT its old PAS 1192 term, the MPDT defines who produces what, when and to what level of detail.

quantity

property of a phenomenon, body, or substance, where the property has a magnitude that can be expressed by means of a number and a reference. for example a measure with a unit.
Quantities can appear as base quantities or derived quantities.
EXAMPLE 1 Length, mass, electric current (ISQ base quantities).
EXAMPLE 2 Plane angle, force, power (derived quantities).
