BIM coordination starts by aligning coordinates, elevations, discipline scope and model versions—before clash review and release—not by comparing “2D vs 3D” slogans.
Where it applies
Multi-discipline MEP and support coordination
Architecture / structure / MEP model federation checks
Installation relationships and maintenance boundaries
Inputs
Discipline models or drawings with version info
Shared coordinate and elevation datum
Support design scope and anchorage boundaries
Confirmed scheme or detailing premises
Outputs and boundaries
Issue list and adjustment notes
Coordinated model / relationship notes
Support detailing and delivery catalogue
Boundary: this page is not an online BIM viewer and does not invent unreviewed clash results or material quantities.
Example
Example: discipline relationships in one environment—used to explain baselines, not as a live layer switch.
How multi-discipline models relate
The integrated model shows co-existing disciplines. The legend is static and does not simulate layer selection.
Example
Example: architecture, structure, MEP and supports in one coordinate system.
Discipline legend
01
Architecture
Spatial boundary / plantroom clearance
02
Structure
Beams, columns and slabs / anchorage boundary
03
HVAC
Ducts / outlets / equipment
04
Plumbing
Water supply / drainage / rainwater
05
Fire protection
Sprinklers / hydrants
06
Electrical
Trays / cables / equipment
07
Support system
Bearing / anchorage / installation relationships
Locate, adjust and review issues
Selecting an issue updates the hotspot and the detail panel together. This is a method illustration, not an approved project conclusion.
Example
Example: hotspots map to check locations on the same integrated model.
01 · Duct × structural beam
Issue found
Spatial relationship conflict
Adjustment
Adjust routing / elevation / structural boundary
Review result
Close the issue after review for release
02 · Fire pipe × cable tray
Issue found
Pipe and tray installation-level conflict
Adjustment
Adjust routing / elevation / crossing sequence
Review result
Update the model after level relationships are confirmed
03 · Pipe × support
Issue found
Support location affects pipe access
Adjustment
Optimize support location / span / node
Review result
Release after support and access relationships are reviewed
04 · Insufficient maintenance space
Issue found
Equipment maintenance boundary occupied
Adjustment
Release maintenance zone / rearrange adjacent systems
Review result
Close the issue after maintenance boundaries are confirmed
From finding issues to release
Coordination is a closed loop: find issues, coordinate disciplines, update the model and review until releasable outputs exist. This module does not auto-rotate.
Model input
Establish the coordination baseline from discipline models, coordinates and source data.
Clash check
Check spatial relationships between architecture, structure, MEP and supports.
Issue markup
Locate clashes and form traceable issue items.
Coordination
Define adjustment principles, responsibility boundaries and sequence.
Model update and support detailing
Adjust routing, elevations, nodes and supports, and confirm installation space.
Review
Check the model again and confirm issue closure.
Release
Form models, drawings and a delivery catalogue for engineering use.
How coordination results enter delivery
Delivery is explained as a readable catalogue. Material quantities are not replaced by tiny full-table bitmaps. Exact file formats follow project agreement.
