Popularly Geometric BIM is used i.e. recreating 3D components of systems & specifications proposed.
- Slower design development, compared to 2D
- Erroneous drawings extracts
- Unstructured Quantity Survey
- Disintegrated models with limited utility
Faster Design Development
BIM Woes!
What has changed?
Synchronous-BIM is an emerging workflow, thanks to Open BIM – ISO 19650 i.e. co-generated data.
- 20-30% faster design development
- Accurate cogeneration -calculations/drawings | BOM/BOQ
Workflow | Geometric 3D
Slower compared to 2D incude longer revisions cycle and Cumbersome to produce high-quality documentation
Workflow | Synchronous 3D
- 30% faster compared to 2D includes revisions high-quality documentation includes LIVE Twin
Why Synchronous BIM works better?
Geometric BIM
Components of a system are modelled independently for visual representation.
Choose from an exhaustive library of objects/families to meet requirements.
Clash detection done separately and retrospectively is cumbersome.
Manufacturing like workflow are at roots of BIM, hence the linear approach.
Changes required are a cumbersome process i.e. slower than 2D.
Synchronous BIM
Components are recognised as part of a system with hot/live connections.
The same object (parametric) is modified by changing properties.
Clash detection synchronous of the modelling process refer RHS/next page.
Standard systems & specifications enable co-generated and high-level detail.
Changes done auto update calculations, drawing annotations and BOM/BOQ variance.
Synchronous clash-detection
Includes pro-active pop-ups and in-platform chronology as a Quality Assurance (QA) measure:
- MEP to Structure / Doors
- Firefighting to MEP
- Plumbing to MEP
- A/c & Ventilation to MEP
- Electrical & ELV to MEP
- MEP to Walls / Facade
Load/Node Considerations
Post the intelligence of design, objectifying elements makes it easier to train resources and have an assembly—line-like delivery.
Scan to BIM / Existing Assets
Similar to Geometric BIM, a LiDAR-generated point cloud is manually traced to create a visual twin.
Al for Automatic Data recognition is on the rise, fueled by drones and iPhones.
Both Europe and Singapore have mandated the digitalisation of all their existing assets
