BIM coordination uses digital building models and associated project information to coordinate designs and construction activities across multiple disciplines.

Individual architectural, structural, mechanical, electrical, and plumbing models can be combined into a federated model, allowing project teams to review how different systems interact.

This makes it possible to identify coordination problems before installation or construction takes place.

BIM coordination does not replace 2D drawings. Many projects still rely on sheets alongside models, and coordination works best when both are reviewed in the same place.

Clash detection is the process of identifying conflicts between elements within one or more BIM models.

For example, a clash might occur when:

• HVAC ductwork intersects a structural beam
• Mechanical equipment conflicts with architectural space
• Electrical systems overlap with plumbing
• Required installation or maintenance clearances are unavailable

Clash detection identifies potential conflicts, while coordination determines how those conflicts should be reviewed, assigned, communicated, and resolved.

A single check can return hundreds of results, so detection only becomes useful when it is connected to a process that sorts real problems from noise and gets them to the right person.

Poor coordination can turn relatively small design conflicts into expensive construction problems.

Effective coordination helps project teams identify issues earlier and creates a structured process for resolving them. A conflict caught in a model review is a design change; the same conflict found on site can mean rework, delay and a difficult conversation about who pays for it.

This can help teams:

• Reduce rework
• Detect design conflicts earlier
• Improve communication between disciplines
• Maintain visibility of outstanding issues
• Reduce delays caused by missing or inconsistent information
• Connect office and field teams
• Improve accountability for issue resolution
• Make project decisions with greater context

On larger projects the benefit grows, because more firms contribute to the same building and each late change can affect several other teams.

A typical BIM-enabled coordination workflow may involve:

The objective is not simply to find as many clashes as possible. Effective coordination helps teams identify the right issues, assign responsibility, and resolve them efficiently.

Coordination continues beyond design and preconstruction.

Field teams need access to current drawings, models, issues, and project context while work is being installed. At the same time, information discovered on site needs to be communicated back to project and design teams.

Connecting these workflows reduces the gap between what is represented digitally and what is actually happening on the construction site.

When a site team can raise an issue against the exact drawing or model location, the office sees the problem in context and can respond without a site visit or a long email thread.

Revizto is the central coordination layer for both 2D drawings and BIM/3D workflows: it brings sheets and models from multiple authoring tools into one shared environment and turns coordination problems into trackable, assignable issues.

Teams can run clash detection with Clash Automation, assign issues to the responsible people, monitor status and keep a record of each decision. Office and field teams work from the same project information, whether they use 2D, 3D, or a combination of both.
