Using digital to transform the construction process
Working with our Partners we have developed an online diagnostic that allows you to assess your organisations BIM and digital maturity and a library of learning resources to enable you to better understand what is needed as you develop your BIM capability.Take BIM assessment
The next stage in the digital revolution has begun. Having transformed retailing, publishing, travel and financial services, digital technology is changing the way we plan, build, maintain and use our social and economic infrastructure. BIM is an intelligent 3D model-based process that gives architecture, engineering, and construction professionals the insight and tools to more efficiently plan, design, construct, and manage buildings and infrastructure.
The Government Construction Strategy mandated the use of Level 2 BIM on all public sector projects, whilst this target has been missed by most, the direction of travel is clear.
What does Level 2 BIM actually mean? A BIM maturity model has been devised to clearly explain the varying levels of competence expected and processes required to meet level 2 and beyond.
Processes around BIM and digital management are a crucial aspect…
BIM Level 2 Maturity
Level 0 (Low Collaboration)
Use of 2D CAD drafting with paper-based or electronic print information and data exchange.
Level 1 (Partial Collaboration)
Use of a mixture of 2D or 3D CAD backed by a common data environment for electronic sharing of drawings and data with a standardized data structure and format managed to BS 1192.
Level 2 (Full Collaboration)
Collaborative working across disciplines with all parties using 3D BIM models, integrated but not necessarily shared. Design information is shared through a common file format such as IFC or COBie. All parties embrace collaborative working and use 3D, data-loaded models to integrate and exchange information.
Level 3 (Full Integration)
Fully collaborative working across all disciplines using a single, shared project model held centrally and accessible to all to modify and share data.
A common misconception with BIM terminology has to do with the dimensions of BIM. We hear colleagues talk about 3D, 4D, 5D and even 6D, but what do these terms mean?
The dimensions are different from the BIM maturity levels. BIM dimensions are inextricably connected to the type of data that can become available through the process. They can be found both in BIM Level 2 and Level 3. In a nutshell, there are four types of BIM dimensions:
- 3D: Refers to 3D generated drawings, at this stage you are at just Level 1 BIM.
- 4D: adds project time management to the model
- 5D: adds project cost data to the model
- 6D: adds Facilities Management of the building in use to the model
BIM Level 2 requires 3D plus time and cost data to be used, Level 3 BIM requires the link to building management, known as 6D.
