Construction Readiness
Coordination Before Construction
A Federated Model Is Only the Beginning of Coordination
Bringing architectural, structural and MEPF models into one environment makes system relationships visible. But visibility alone does not mean a project is coordinated.
Effective VDC coordination requires a controlled process for identifying conflicts, understanding their construction impact, assigning resolution responsibility, updating models and verifying that issues are actually closed.
- Architectural, structural and MEPF federation
- Hard-clash and clearance review
- Routing and spatial coordination
- Equipment-access review
- Openings and penetration coordination
- Constructability-focused issue resolution

More Than Clash Detection
Coordination is structured around model quality, spatial relationships, constructability, issue ownership and verified resolution.
02 / CLASH REVIEW
Clash Detection
Structured review of conflicts between building systems and construction elements.
- Hard clashes
- Soft clashes
- Clearance conflicts
- Routing conflicts
- Structural interfaces
03 / CONSTRUCTABILITY
Constructability Review
Review focused on whether systems can realistically be installed, accessed and maintained.
- Service access
- Equipment clearances
- Installation sequence
- Congested zones
- Maintainability
04 / ISSUE MANAGEMENT
Coordination Issue Tracking
Structured issue records help separate identified conflicts from resolved conflicts.
- Issue identification
- Discipline assignment
- Resolution tracking
- Recheck status
- Closure verification
05 / OPENINGS
Openings & Penetrations
Coordination of MEP penetrations and required openings with structural systems.
- Wall openings
- Slab penetrations
- Sleeves
- Builder's work
- Structural interfaces
06 / MODEL REVIEW
Coordination Model QA/QC
Review of model inputs and coordination status before downstream construction use.
- Model completeness
- Discipline alignment
- Coordinates
- Model versions
- Coordination status
Coordination Workflow
From Federated Models to Verified Coordination
A repeatable coordination sequence helps project teams distinguish between an issue being found and an issue being resolved.
01
Receive Models
Collect current architecture, structure and MEPF models.
02
Validate Inputs
Review model versions, coordinates and basic model readiness.
03
Federate Models
Combine disciplines into the coordination environment.
04
Detect Conflicts
Run targeted reviews for spatial and physical conflicts.
05
Assign Issues
Organize coordination issues by discipline and responsibility.
06
Resolve & Verify
Update models, rerun review and confirm issue closure.
Clash Management
Clash Detected Does Not Automatically Mean Clash Resolved
A clash report is an input to coordination, not the final output. Each meaningful issue must be reviewed in context, assigned, corrected and verified against the updated federated model.

Why Coordinate Before Installation?
01
Better Spatial Visibility
Teams can review system relationships before they become field conflicts.
02
Clearer Issue Ownership
Coordination issues can be organized by discipline and required action.
03
Improved Constructability
Routing, access and installation constraints are reviewed earlier.
04
Better Documentation
Coordinated model information supports clearer downstream drawings and outputs.
Coordination Technology
Digital Tools Supporting VDC Coordination
Software supports the coordination process, but disciplined model review and issue management remain central to delivery.
Frequently Asked Questions
VDC & BIM Coordination FAQs
What is BIM coordination?
BIM coordination combines relevant discipline models into a common digital environment so spatial conflicts, interfaces and constructability issues can be reviewed before installation.
Is clash detection the same as BIM coordination?
No. Clash detection identifies potential conflicts. Coordination also requires reviewing whether those conflicts are meaningful, assigning resolution, updating models and verifying closure.
Which disciplines can be coordinated?
Coordination may involve architectural, structural, mechanical, electrical, plumbing, fire-protection and other project-specific models.
Can you review equipment clearances?
Yes. Coordination can include equipment-access, maintenance and service-clearance review when the project model and scope provide the required information.
What coordination deliverables can be provided?
Depending on project scope, outputs can include federated models, clash reports, issue registers, coordinated discipline models, coordination views and construction-oriented model information.
