The BIM Execution Plan (BEP) is a formal document that defines how the project will be executed, monitored and controlled with regard to BIM. A BEP is developed to provide a master information/data management plan and to assign of roles and responsibilities for model creation and data integration at project initiation.
The BEP must align the project procurement strategy needs and requirements with the Project BIM Brief, client technical standards, team member skills, construction industry capability, and technology maturity. Through this process, the team members and the project management jointly agree on how, when, why, to what level, and for which project outcomes BIM will be used.
In those projects where construction information is available during the design phase (using the D&C project procurement strategies) the BEP addresses both design and construction activities. Where a DBB method (traditional) procurement strategy is used, a separate BEP for design and potentially for construction is developed and submitted to the client — with specific attention to model and data handover from the design team to the construction team.
The BEP document should be considered a living document and be continually developed and refined throughout the project development lifecycle (as required.) This ensures the project remains on schedule and meets briefed requirements. Include the proposed method for facilitating this (eg. scheduled review meetings) in the initial BMP.
The Design Team BIM Manager submits the BEP to the client for review and approval before the start of schematic design. Other than uses of BIM excluded by the Project BIM Brief, the Design BMP, at a minimum, addresses the following:
- Legal status the Design Model will have for construction (binding, informational, reference, reuse.)
- File exchange protocol.
- File formats used for project submittal and file exchange.
- Proposed BIM software to be used by each technical discipline team member.
- A technical evaluation of the options to match the Information Technology (IT) technical needs to the size and complexity of the project, and to provide access by the Design/Construction Team and various project stakeholders, peer reviewers, etc.
- Strategy for hosting, transfer, and access of data between technical disciplines and the use of a CDE (model server, extranet, permitted uses, access rights, security, etc.)
- Strategy to establish and manage the principals of shared file server, if used. If not using a shared file server, provide the strategy for model exchange and hand
- Project schedule aligned to BIM development and progress submittals in compliance with the client’s submission instructions. Schedule to include:
– Software compatibility testing schedule.
– Proposed meetings and their purpose (design coordination/clash detection, BMP review, etc.)
– Progress BIMs per design document submission. Specify how much time the Progress BIM recipient has to advise the author/s if it satisfies their specified requirements, or not. Documentation of any proposed deviation from the Project BIM Guide standards — for client approval.
- Coordinators for all major disciplines (Architect, Civil, MEP, Structural, etc.)
- BIM qualifications, experience, and contact information for the following:
– BIM Manager
– Lead BIM
- Overall plan to achieve client BIM requirements.
- The project procurement strategy (DBB, D&C, IPD) and how the Design BIM will support the project delivery activity. Modelling considerations
- The proposed development of Model Elements throughout the project, including the Level of Development (LOD) of each, and the author responsible for developing it at each phase of the project.
- Strategy to import Program for Design (PFD) information.
- Methods for showing functionality of occupants’ requirements (proximity of spaces, walking distances, sightlines, etc.) and circulation paths for the delivery, supply, processing and storage of materials, etc. (eg. graphics, animated models.)
- Methods to show major building equipment space clearance reservations for operations, repair, maintenance and replacement. (eg. graphics, animated models.)
- Energy modelling strategies.
- Strategy to update and coordinate changes during construction into the final BIM model deliverable files.
- Strategy to integrate facility management information (e.g. GBXML.)
