We are launching another episode as part of the series: „BIM Experts”!
Paper will accept everything, but the construction site will verify every mistake. An effective BIM Execution Plan (BEP) is not a bureaucracy, but a precise manual for exchanging information.
Many Investors treat the BEP (BIM Execution Plan) as „another thick document” that lands in a drawer as soon as the contract is signed. This is a mistake. If the BEP is not a living communication tool, it becomes just a wish list rather than a real construction support.
At Rex-Bud Construction, we know that a well-constructed BEP is the insurance policy for your investment. This is where it is decided whether the data in the model will be useful or become just digital chaos.
Why won't „copy-paste” from the internet work?
Every investment has different characteristics. A different set of information is needed by a logistics hall and another by a manufacturing plant. An effective BEP must answer the question „Why does the Investor need this model?”.
Checklist of essential elements (Must-Have for the Investor):
BIM Goals (BIM Goals) - Concrete instead of slogans. Instead of writing „we want BIM”, we define: is the model for interprofessional coordination, for pre-measurement or perhaps for facility management? The goal determines the scope of work for all parties.
Liability matrix (LOD/LOI) - Who provides what? This is where we determine the level of detail of geometry (LOD) and information (LOI). Without this, the structural designer may prepare a model that is „too light” and the installer „too heavy”, preventing reliable coordination.
Common Data Exchange (CDE) standards - Where is the „truth”? The Common Data Environment is the heart of the project. In the BEP we need to be clear: what platform we are working on, how we name files (naming convention) and how the documentation approval process works. A lack of a standard is a guaranteed mess in drawing versions.
Software and file formats (OpenBIM). To ensure that the developer is not locked into one environment for years, we rely on open formats (IFC). BEP needs to define software versions to avoid cross-industry compatibility issues.
What does the Investor gain from this approach?
Control over the process: You know exactly what you will receive and when. Time saving: You eliminate sending hundreds of emails asking „where is the latest file?”. Clean data: The post-construction model is ready to support building operations (Digital Twin).
BIM without a well-thought-out BEP is just expensive 3D imagery. With a plan - it's a powerful tool for cost and time optimisation.
Question for Investors and Project Managers: Have you ever had a case where a BIM model was not usable on site because it was missing key information? Share your experiences in the comments!
