2.2.2. Definitions used in project management

(a) Building Information Modelling

Use of a shared digital representation of a built asset to facilitate design, construction and operation processes to
form a reliable basis for decisions

Using BIM and both Parts of ISO 19650, consulting engineers can demonstrate, in real time, the relevancy and the compliance of
their design. The concept of ‘shared information’ relates to the possibilities in BIM of using digital information to simulate and dis-
play the project at each stage of development. Sharing this structured information with all relevant parties also facilitates the deci-
sion-making process, including final approval. Using open standards to structure the information allows it to be shared more easily.

(b) BIM Execution Plan
Plan that explains how the information management aspects of the appointment (3.3) will be carried out by the
delivery team (3.17)

A BIM Execution Plan (BEP) defines how, why, when and by whom the information modelling aspects of the contract will be carried
out. The use of BIM should be clearly agreed with the client and specified in the contract alongside the ‘needs’ which fulfil the
agreed contractual obligations.

A BEP should be considered part of the quality architecture of a project in addition to, or implemented in, the Project Management
Plan. It should detail not only how information is created and delivered, but also the ‘why’ (defining the BIM use), and the ‘who’
(assigning responsibility for it). ISO 19650 - Part 2, which concentrates on the delivery phase of the assets, provides some help in
defining the ‘how’ and the ‘who’. The ‘why’ is usually part of the guidance for implementing the BEP in the definition of proposed
BIM uses.

(c) Level of information need
The level of information need is:
Framework that defines the extent and granularity of information.

Note 1 to entry: One purpose of defining the level of information need is to prevent delivery of too much information.

It has to be noted that the ISO committee has decided to refuse to use any acronyme for this, to underline there is no tool for that.
In the same way, “level of information” is always used with the word “need”. 13
