7 Pro Tips To Perform Crossdisciplinary
BIM Coordination
2
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
other.

• 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
  tools.
• 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
  license?

• 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
  rules.

Tip 5 Specify the purview of model
checking.

• 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.

11
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.

Summary

• 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.
