BIM Coordination

Building Information Modeling coordination for complex commercial, institutional, and multi-trade projects.

BIM Coordination

BIM Coordination

BIM Coordination is the process of integrating architectural, structural, and MEP models into a single federated model to detect and resolve spatial conflicts before construction begins. We provide BIM coordination services for commercial, institutional, and complex residential projects, producing coordinated models, clash detection reports, and coordination drawings that prevent field conflicts from becoming construction delays. All work is delivered in Revit and IFC formats.

Scope

Disciplines coordinated.

Each discipline model is managed, coordinated, and clash-checked against every other. No routing or structural element escapes the review cycle.

  • Architectural BIM

    Revit architectural model management, element standards, and coordination reference model.

  • Structural BIM

    Structural framing model integration, beam and column clearance verification, and connection coordination.

  • MEP Coordination

    Mechanical, electrical, and plumbing routing coordination across all three disciplines simultaneously.

  • Clash Detection

    Hard and soft clash detection run between all discipline model pairs with BCF-format issue reports.

  • 4D Scheduling Coordination

    Model-linked schedule sequencing for phased construction and logistics planning.

  • As-Built BIM Documentation

    Field-verified model updates reflecting installed conditions for owner facilities use.

Coordination Cycle

The coordination cycle.

  1. Model Intake and Setup

    We receive architectural, structural, and MEP models from the project team, establish the project coordinate system, and set up the federated model environment. Any model quality issues (missing data, coordinate conflicts, incorrect elements) are logged and resolved before coordination begins.

  2. Clash Detection Rounds

    Hard clashes (physical element intersections) and soft clashes (clearance violations) are run between all model disciplines. Clash reports are issued in BCF format, organized by trade, location, and severity, and distributed to the responsible design team members.

  3. Coordination Meetings

    We facilitate coordination review meetings with the project team to review clash reports, assign resolutions, and confirm the responsible party and required action for each item. Coordination meeting minutes and updated clash logs are maintained.

  4. Resolution and Model Update

    As design team members resolve assigned clashes, models are reloaded and re-run. The coordination cycle continues until the model meets the project's coordination completion criteria and the clash count drops below the agreed threshold.

Deliverables

What you receive.

Every BIM coordination engagement produces structured, documented outputs. Scope is confirmed at model intake and adjusted per project size and trade count.

  • Federated Model Setup

    Assembly and management of the federated project model incorporating all discipline models with a coordinated project coordinate system and file structure.

  • Clash Detection Reports

    Organized clash detection reports in BCF format, with hard clash and soft clash sets run between all discipline pairs. Distributed to responsible design team members for resolution.

  • Coordination Drawings

    2D coordination drawings extracted from the federated model showing resolved MEP routing, structural clearances, and coordination conditions for field reference.

  • Issue Tracking Log

    A running clash and coordination issue log tracking every identified conflict, its assigned owner, current status, and resolution date.

  • Coordination Completion Report

    A final report documenting the coordination scope, clash statistics (initial count, resolution count, remaining items), and sign-off confirmation from responsible parties.

  • As-Built BIM Update

    Post-construction model update reflecting field-verified conditions, available as a deliverable for owner facilities management.

Why It Matters

The cost of skipping coordination.

Clashes discovered in the field cost 10 to 100 times more to resolve than clashes detected in the model. BIM coordination is not a luxury on complex projects: it is the only reliable way to verify that a multi-trade installation fits in the available space before the first conduit is hung. The investment in coordination is returned in the first avoided field conflict.

LOD Reference

Level of Development: what we deliver.

LOD defines the precision of each model element. CADTRI coordinates to LOD 300-400 depending on trade and project phase, with full documentation of which elements reach which level.

LOD LevelDescription
LOD 100

Conceptual mass or symbol. Elements represent approximate size, shape, location, and orientation.

LOD 200

Generic systems and assemblies with approximate quantities, size, shape, and location.

LOD 300

Specific assemblies accurately modeled as quantity, size, shape, location, and orientation.

LOD 350

Elements include interfaces and connections to other systems and disciplines.

LOD 400

Fabrication and assembly-level detail. Elements include complete geometry and finish information.

FAQ

Common questions.

What LOD is standard for permit coordination?
LOD 200 to 300 is typically sufficient for permit-level coordination. LOD 350 to 400 is used for detailed construction coordination and is required for projects with complex MEP installations or prefabricated MEP assemblies.
What software formats do you accept?
We work primarily in Autodesk Revit (RVT) and accept IFC-format models from consultants using other BIM platforms. We can also coordinate from Navisworks (NWD/NWC) for clash detection when full model editing is not required.
What is BCF format and why does it matter?
Building Collaboration Format (BCF) is the open standard for communicating BIM coordination issues. BCF files can be opened in virtually all BIM platforms, ensuring that clash reports are actionable by every member of the project team regardless of their software.
How many clash detection rounds are included?
The number of rounds depends on the project complexity and the team's resolution velocity. We structure the engagement around a defined coordination completion criterion (such as zero hard clashes and approved soft clash waivers) rather than a fixed number of rounds.

Designed For

Who this service is for.

  • Commercial General Contractors

    Managing complex commercial projects where MEP and structural conflicts discovered in the field create costly delays.

  • Architects on Complex Projects

    Who need BIM coordination services to integrate structural and MEP consultant models with the architectural design.

  • Owners and Developers

    Requiring a coordinated BIM deliverable for facilities management, commissioning, or contractual BIM requirements.

  • MEP Engineers

    Who produce MEP models and need a coordination partner to run clashes against architectural and structural and manage the resolution process.
