BIM Execution Plan
BEP BIM Execution Plans
BEP BIM Execution Plans are essential for outlining the agreed-upon processes, roles, and responsibilities for using BIM on a specific project. At CADScope, we are experts at creating these plans for our clients in the UK and overseas to help ensure that all stakeholders are aligned and working towards common goals. By implementing BEPs, organisations can streamline workflows, improve communication, and reduce errors, ultimately leading to more efficient and successful projects.
Level 0 BIM: Paper-based drawings + zero collaboration
Level 0 BIM refers to not operating collaboratively at all. If you’re using 2D CAD and working with drawings and/or digital prints, you can safely say you’re at level 0. Today, most industries are working above this level. However, not every professional in the industry has sufficient BIM training, and some projects do not include the use of BIM in contract specifications.
Level 1 BIM: 2D construction drawings + some 3D modelling
Using 3D CAD for concept work but 2D for drafting production information and other documentation probably means you're working Level 1 BIM. At this level, CAD standards are managed according to the standard of BS 1192:2007, and electronic data sharing is carried out from a common data environment (CDE), usually handled by the contractor. Many firms are at Level 1 BIM, which doesn’t involve much collaboration, and each stakeholder publishes and manages their own data.

Level 2 BIM: Teams work in their own 3D models
Level 2 BIM begins to add in a collaborative environment. BIM Level 2 was made mandatory in April of 2016 on all publicly tendered projects in the UK. France followed shortly after with their own mandate in 2017.
At level 2, all team members use 3D CAD models but sometimes not in the same model. However, the way in which stakeholders exchange information differentiates it from other levels. Information about the design of a built environment is shared through a common file format.
When firms combine this with their own data, they save time, reduce costs, and eliminate the need for rework. Since data is shared this way, the CAD software must be capable of exporting to a common file format, such as IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange).

Level 3 BIM: Teams work with a shared 3D model
BIM level 3 is even more collaborative. Instead of each team member working in their own 3D model, Level 3 means that everyone uses a single, shared project model. The model exists in a ‘central’ environment and can be accessed and modified by everyone. This is called Open BIM, meaning that another layer of protection is added against clashes, adding value to the project at every stage.
Benefits of Level 3 BIM are:
- Better 3D visualisation of the entire project
- Easy collaboration between multiple teams and trades
- Simplified communication and understanding of design intention
- Reduced rework and revisions at every stage of the project
BIM Levels 4, 5, 6
Levels 4, 5, and 6 BIM: Adding in scheduling, cost, & sustainability information
BIM level 4 brings a new element into the information model: time. This information includes scheduling data that helps outline how much time each phase of the project will take or the sequencing of various components.
Level 5 BIM adds cost estimations, budget analysis, and budget tracking to the information model. When working at this level of BIM, project owners can track and determine what costs will be incurred during the length of the project.
Level 6 BIM information is useful for calculating the energy consumption of a building before it's built. This ensures that designers consider more than just the upfront costs of an asset. Level 6 BIM ensures accurate predictions of energy consumption requirements and empowers stakeholders to build structures that are energy-efficient and sustainable.
Benefits of Levels 4, 5, and 6 BIM:
- More efficient site planning and scheduling
- More efficient hand-offs between steps in the construction stage
- Real-time cost visualisation
- Simplified cost analysis
- Reduced energy consumption in the long run
- Better operational management of the building or structure after handover
