4.4. BIM uses

As already mentioned, the BEP has to be developed at a very early stage of a project. It not only explains how the information will be
delivered but also, in accordance with the risk analysis, why. The BIM uses have to be selected in relation to the goals and require-
ments of the project and show real added value in the process of design and construction. This directly affects which BIM uses can
be implemented in each project stage, as well as the results expected from them. How the uses are described is tightly related to
the level of information need in order for them to be properly executed.
For the purposes of defining BIM uses and their correlation to specific project stages, an Information Delivery Plan is needed as a
basis for project stage definitions, as per ISO 19650 – Part 2. Each individual BIM use is to be defined with a specific goal in terms
of cost, time, quality or risk, related to the project or another secondary use.

Each use should reference a set of significant inputs or reference documents or information sets, such as: project stages, reference
coordinates system, classification systems, engineering guidelines/standards, local requirements related to the project, etc. A set of
other details should also be defined, as follows:

• project inputs – the input requirement necessary for each specific BIM use
• process integration – the workflow and stakeholders to be included in the process, along with integration into other
project processes
• deliverables – the end results of the given process
• expected benefits – the reason that specific BIM uses are utilised on a project
• training and skills necessary for stakeholders to be able to execute or utilise the results of each specific BIM use
• technology deliverables – software vendors and types, files and formats and other technical information regarding the
deliverables and their utilisation. This is tightly related to the section covering interoperability

BIM uses should not be an exhaustive list, since new uses are being developed and the existing ones improved, but the aim of this
section is to list some of the most common usage and some of their benefits.

As already mentioned, it’s strongly recommended to refer to national guidance, published for instance by buildingSmart interna-
tional chapters, to introduce BIM uses in specific BEP.
