Title: 7 Pro Tips To Perform Crossdisciplinary BIM Coordination

7 Pro Tips To Perform Crossdisciplinary
BIM Coordination
What is multidisciplinary coordination in
Building Information Modeling (BIM)?
  • Multi-trade coordination or multi-disciplinary
    coordination involves workflows and tools to
    combine 3D models from Architectural, Structural,
    MEP, and FP disciplines. Cross-disciplinary BIM
    coordination supports collision detection and
    resolution and drives higher data accuracy
    validity with preemptive collision reports,
    coordination meetings, viewpoint creation, RFIs,
    submittals, etc. The most common form of BIM
    coordination is model interference checking.
    Collisions or clashes can be identified as hard
    and soft clashes. Structural engineers create a
    load-bearing wall and HVAC engineers model an
    air-conditioning system. There is a probability
    of HVAC systems interfering with load-bearing
    walls causing a clash. These clashes need to be
    reported to the design team in the
    preconstruction stage.

Tip 1 Place models accurately with each
  • 3D models need to be set precisely. Indifferent
    coordinate systems or dimensional inaccuracies
    can create collisions when models are combined.
    3D models from multiple disciplines need to be
    combined within the same coordinate system with
    higher accuracy. BIM modelers need to understand
    a dual coordinate system exists in Revit Shared
    and Internal coordinates. Understanding Survey
    Points and Project Base Points support improved
    model placement. Linking models, using Worksets,
    and understanding the difference between Project
    North and True North drives accurate model
    placement between various disciplines.

Tip 2 Select the right BIM coordination tools.
  • There are various BIM coordination tools
    available and their selection depends on the
    application. Asking 3 simple questions can make
    it simple to select the right BIM coordination
  • Is the 3D model or document generated in a
    single program or multiple programs?
  • What are the tools used by the company for
    interdisciplinary BIM coordination?
  • Are the BIM coordination tools supported by a

  • 3D BIM modeling programs like Revit reinforce
    modeling teams to identify collisions. Tools like
    iFieldSmart Technologies can be used to identify
    and resolve clashes and create viewpoints.
    Levelwise and trade-wise clashes make it easier
    to identify and resolve clashes and visualize
    graphical reports. A Common Data Environment or
    CDE provides teams the capability to conduct
    interference checks with tools like Navisworks
    and iFieldSmart Technologies. Keeping 3D models,
    drawings, and other documentation on a single
    cloud platform can coordinate trades seamlessly
    across the entire project. Advanced model
    coordination tools provide endless possibilities
    to detect interferences, build coordination
    reports, and share them with other teams in the
    project. These advanced tools include Navisworks
    Manage, iFieldSmart Technologies, Solibri, etc.

Tip 3 Exporting 3D models to IFC format.
  • For multidisciplinary coordination, project teams
    deploy various 3D BIM modeling software.
    Connected construction requires the utilization
    of tools or software like Revit, Navisworks,
    Tekla, and iFieldSmart Technologies. Each
    software produces files in different formats.
    However, BIM modelers must combine and generate a
    3D model in IFC format with BIM coordination.
    Producing an accurate IFC file requires precise
    data mapping from native file formats to IFC.

Tip 4 Merging 3D models into a single
multidisciplinary 3D model.
  • Multiple IFC models can be combined into a single
    coordinated model. This serves as a base for
    preemptive BIM coordination. Revit can be used to
    add 3D models from various categories with the
    appropriate rules and checklists. This helps
    identify and classify collisions whilst setting

Tip 5 Specify the purview of model
  • After the models have been coordinated, it is
    important to identify the scope of BIM
    coordination. Answering questions can support
    specifying the scope of checking 3Dmodels.
  • Are the 3D models only checked for
    interferences or data accuracy or validity?
  • Is the space validation accurate? Do modeled
    spaces meet design conditions?
  • Are the installations modeled accurately with
    accurate distances from construction components?
  • Does the coordination include assessing
    installation distances and following standards?

  • Answers to the above questions make it easier to
    model quicker, detect interferences, identify
    missing data, etc.

Tip 6 Check model checking rules.
  • Creating model checking rules or user-defined
    rules to specify elements for model checking and
    conditions. For example, BIM coordination can be
    deployed to check collisions between air
    conditioning models and architectural models. BIM
    tools provide teams with filtering,
    classification, and group rules to check what is
    needed. The very need to specify rules for model
    checking can be extensive, yet powerful.

Tip 7 Carrying out a 3D model check and
sending out reports.
  • Checking a 3D model with predefined rules or
    using tools like iFieldSmart Technologies helps
    identify collisions early in the preconstruction
    stage. Issue management reports that can be
    filtered trade-wise or level-wise can be
    leveraged. These reports can be shared with
    multiple teams and disciplines to resolve
    clashes. Construction management tools from
    iFieldSmart Technologies make it easier to assign
    multiple tasks through task management. Clash
    coordination dashboard from iFieldSmart showcases
    extensive clash data for mechanical, electrical,
    structure, plumbing, etc. Open or overdue status
    helps teams identify and resolve clashes quicker.

  • iFieldSmart Technologies is an end-to-end
    construction management tool that drives
    connected construction for various teams back
    office and field teams. An easy-to-use single
    dashboard provides comprehensive project
    information for field teams to coordinate with
    other team members. For more information on
    iFieldSmart Technologies, schedule a demo.
