7 Pro Tips To Perform Crossdisciplinary BIM Coordination
1. 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.
3. 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.
4. 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?
5. 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.
6. 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.
7. 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.
8. 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?
9. .
Answers to the above questions make it easier to model quicker,
detect interferences, identify missing data, etc.
10. 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.
12. 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
