What is BIM Levels ?

 What is BIM Levels ?





  • Level 0 BIM - CAD
    • Project promotes zero collaboration and makes use of paper-based 2D CAD drafting techniques.
    • Mainly utilized for Production Information.

  • Level 1 BIM - 2D & 3D
    • 3D CAD is used for conceptual works, 2D is used for the generation of statutory approval documentation and Production Information.
    • Data sharing happens electronically using a common data environment (CDE) managed by the contractor.

  • Level 2 BIM - 4D & 5D
    • This level promotes collaborative working by giving each of the stakeholders its own 3D CAD model
    • An information exchange process which is specific to that project and coordinated between various systems and project participants.
    • Level 2 BIM is prescribed by the UK Government for public sector projects.

  • Level 3 BIM - 6D
    • Level 3 has not yet been fully defined, however the vision for this is outlined in the UK Government's Level 3 Strategic Plan.
    • Level 3 concept enables all the participants to work on the same model simultaneously which eliminates the chance of conflicting information.

BIM D's (dimensions) ?  – 2D, 3D, 4D, 5D, 6D, 7D, 8D. 2D BIM  – 2D drawings (with x & y axis) & documentation, views, plans, etc. 3D BIM  – shared information model used for visualization purposes, coordination, etc. 4D BIM -  (4D = 3D + TIME SCHEDULE) adds an extra dimension of information to a project information model in the form of scheduling data. 5D BIM -  (5D = 3D + TIME SCHEDULE + COST) assemblies with time schedule constraints and then with cost-related information. 6D BIM -  (6D = 3D + TIME SCHEDULE + COST + MAINTENANCE) assemblies with all aspects of project life-cycle management information. 7D BIM -  (7D = 3D + TIME SCHEDULE + COST + MAINTENANCE + SUSTAINABILITY) optimizes asset management from design to demolition. 8D BIM  - (8D = 3D + TIME SCHEDULE + COST + MAINTENANCE + SUSTAINABILITY + PREVENTION) for accident prevention through Design.

What is Asset Management ?

Image
  What is  Asset Management  ?  Asset management is defined as the coordinated activity of an organization to realize value from assets. The availability of appropriate and reliable information about assets is vital for effective asset management as it supports decision making, planning and execution of activities on assets. By providing a structured framework for the creation, collation and exchange of information about assets, BIM supports effective asset management. Thus, BIM must provide information covering the whole life cycle of assets. Benefits of  BIM  in  Asset Management  are :- Reduced project start-up costs. Reduced construction and operational costs. Better life cycle management. Reduced management process costs. Greater clarity on long-term in-service performance expectations and the consequences of design-stage decisions over life cycle performance and cost.

What is COBie ?

  What is  COBie  ? COBie -  Construction Operations Building Information Exchange. COBie  is an international standard for building data exchange & most common use is in product data handover from construction to operations. The most common representation of  COBie  is the COBie spreadsheet . The idea behind  COBie  is that the key information is all pulled into one format and shared between the construction team at defined stages in a project. COBie  helps organizations to electronically capture and record important project data at the point of origin, including equipment lists, product data sheets, warranties, spare parts lists, and preventive maintenance schedules. This information is essential to support operations, maintenance and asset management once the built asset is in service. Replacing reliance on uncoordinated, often paper-based, handover information typically created by people who did not participate in the project and delivered many months after the client has take
