Q1. What is the BEP and how does it relate to your EIR?
It is probably easier to think about the EIR first. The EIR (Employer’s Information Requirements) is a pretender document prepared by the Employer, which sets out the information to be delivered and the standards or processes to be adopted by the supplier as part of the project delivery process.
The BEP (BIM Execution Plan) is produced by the supply chain as a response to the EIR, detailing how its requirements will be met.
In accordance with PAS 1192-2:2013, the BEP should cover a number of aspects such as resourcing, capabilities and IT tools and processes.
Q2. What is COBie and when do I deliver COBie data?
COBie (Construction Operations Building information exchange) is a data standard to manage the data coming from BIM models into the client organisation. It was developed by the US Corps of Engineering. COBie data is delivered, via spreadsheet exchange, along with existing contract deliverables, at key stages during the life of an asset to help inform owner or operator decision making.
Q3. What is clash detection?
There are many models in BIM. A model is created by each discipline (MEP, architectural, structural etc.) independently and it is important to know if there are any “clashes” in the design, for example if parts of the structure clash with the M&E equipment. In the past clash detection would take place during the construction phase, when clashes would need fixings on-site, causing added expense and delays.
With BIM, at the design stage the individual discipline models are combined into a federated model using specific software. This software carries out clash detection, based on a series of rules, and highlights potential issues. This means that constructability issues can be resolved before construction begins, saving both cost and time.
Q4. How is the BIM model provided by the supply chain at handover used in operation?
On completion of the new construction project, the project information model (PIM) is passed to the client, together with all the relevant handover information.
