Overview of BIM maturity levels and their relevance in job market
BIM maturity levels are related to Building Information Modeling (BIM) standards in the construction industry.
Connection between maturity levels and BIM dimensions discussed in previous videos.
What is BIM Maturity?
Refers to the richness and level of data in a BIM model.
Involves different dimensions maintained by various stakeholders.
Introduced by Mark Buu and Mevin Richards in 2008.
BIM Maturity Levels
Level 0 BIM
Utilizes 2D CAD drafting techniques.
Minimal to no collaboration between stakeholders.
Essentially non-BIM process, only basic 2D drawings.
Level 1 BIM
Incorporates digital tools for 2D and 3D architectural drawings.
Involves file and data sharing through a Common Data Environment (CDE).
Collaboration is non-existent or partial.
Key aspects:
3D and 2D drawings
Advanced file sharing strategies
Level 2 BIM
Developed from the UK Government standards (UK 1192).
Mandatory for publicly funded projects.
Incorporates time (4D) and cost (5D) dimensions.
Features:
Collaboration with various stakeholders
Advanced file sharing and interoperability
Key terms: BIM protocol, BIM execution plan, model federation, common data environment (CDE).
Common Data Environment (CDE)
Allows various BIM tools to export into open source formats (IFC, COBie).
Facilitates data sharing among teams using different software packages.
Level 3 BIM
A newer concept not fully defined in the industry.
Represents a fully collaborative environment using a single central shared model.
Maximizes coordination and minimizes interferences among disciplines.
BIM Dimensions Beyond Level 3
6th Dimension: Energy use and sustainability assessment.
7th Dimension: Facilities management and life cycle analysis.
8th Dimension: Building safety, security, and emergency plans.
Summary of BIM Levels
Level 0: 2D drafting only
Level 1: Basic 3D modeling
Level 2: Incorporates time and cost dimensions
Level 3: Full collaboration and inclusion of all dimensions
Conclusion
Level 3 BIM allows for a comprehensive understanding and management of buildings throughout their life cycle, aiding in the creation of smart cities and digital twins.
