Pre-appointment and Delivery team’s BIM Execution Plan (BEP) Guidance. The BEP is a key component of successful BIM delivery, it is the mechanism for all appointed parties to respond to the clients overall delivery requirements. The BEP is a live project level document which will be consistently updated throughout the project as required. A BEP should first be developed pre-appointment to aid the procurement process and then this should be updated and maintained by the delivery team as a whole post-appointment. This guidance document is applicable to both BEPs and walks through the purpose of the BEP. The guidance document explains the sections which should be included in the BEP to define how the design team will meet the appointing parties requirements.
