BIM coordination and clash detection.

BIM coordination, in one paragraph.

BIM coordination is the discipline of federating every discipline's model of a project — architecture, structure and MEP — into one navigable model, checking the models against each other, and resolving conflicts before construction. Clash detection is the automated check at its centre: software compares the geometry of every model and reports where elements collide or break clearance rules, so the team can decide who changes what.

ConstruBIM runs this as a managed service: we federate every discipline into one model and run clash cycles until conflicts are resolved on screen instead of on site.

Hard, soft and workflow clashes.

• Hard clash — two elements occupy the same space, for example a duct passing through a beam.
• Soft clash — elements do not touch but break a required clearance, such as maintenance access or insulation space.
• Workflow clash — a sequencing or information conflict, such as work modelled before its dependency is approved, or two teams working to different versions.

The rules for all three are set up front in the BIM Execution Plan, with the coordination cadence and the clash tolerance for each discipline pair. See BIM implementation for how the plan is built.

From execution plan to a model that runs clean.

• Plan. BIM Execution Plan, level-of-development matrix and common data environment set up against your standards.
• Federate. Each discipline's model is assembled into one federated model, validated against the project's model validation checklists.
• Test. Clash tests are run on the federated model against the rules in the BIM Execution Plan.
• Resolve and report. Issues are tracked and closed in BCF, coordination meetings are held and reported, and the cycle repeats until the model runs clean.
• Hand off. The federated model and its records go into the common data environment, governed to ISO 19650.

What you receive.

• Federated model assembly
• Hard & soft clash matrices
• Issue tracking & BCF resolution
• Coordination meeting reports

Coordination at the scale of an airport.

On the Mexico City International Airport (NAICM) the federated model was, at the time, the largest in the world, coordinating dozens of disciplines on a 743,000 m² terminal. ConstruBIM built a custom clash-detection clustering API that prioritised thousands of clashes by spatial concentration, so teams always resolved the densest conflicts first.
