BIM project coordination anticipates conflicts between disciplines, avoids rework, and improves project performance. In this guide, discover what it is, how to apply it in practice, and the mistakes that can compromise the process.
Project coordination has always been a critical step in civil construction, and with BIM, it has become more efficient, visual, and collaborative.
Ultimately, integrating disciplines such as architecture, structure and installations A single digital model allows you to detect and solve problems before they become headaches on the construction site.
However, many professionals still have doubts about how to perform efficient BIM coordination, which tools to use, and how to avoid the most common mistakes.
In this article, you will understand all of this in a clear, practical way, based on Cadbim's technical experience.
Ultimately, compatibility means building with greater safety, less waste, and better results.
What is project coordination in BIM?
Project compatibility It is the process of checking and adjusting the models from the various disciplines involved in a project — such as architecture, structure, electrical, plumbing, air conditioning, and fire prevention — so that they work together without physical or technical interference between them.
In BIM (Building Information Modeling), this verification becomes more visual, precise, and proactive.
Intelligent three-dimensional models allow for virtual simulation of construction before it is carried out on-site.
Thus, it is possible to detect conflicts quickly, gain predictability, and make informed decisions.
This process is known as clash detection: automatic detection of collisions or overlaps between elements of different models.
Why is compatibility analysis essential for the success of a project?
Without proper coordination, the risk of error is high. Examples include pipes running where a beam should be, ducts interfering with ceilings, or electrical outlets lacking adequate space.
These situations are common when projects are done in isolation, without integration between disciplines.
In addition to technical problems, this generates:
- Rework on site, with improvised corrections;
- Schedule delays, due to last-minute adjustments;
- Increase in costs, both in terms of materials and labor;
- Waste of resources, due to mistakes that could have been avoided;
- Decline in productivity, since the execution flow is interrupted.
In BIM, compatibility analysis acts as a "quality filter" before execution. It allows for digital corrections that would be much more expensive to correct physically.
How does the compatibility process work in practice?
Below, you'll find the ideal step-by-step process for a well-executed compatibility assessment using the BIM methodology:
1. Alignment meeting between disciplines
Before starting to check for conflicts, it is essential that all technical teams are aligned. This involves:
- Define a delivery schedule for each subject;
- Establish modeling standards (level of detail, coding, etc.);
- Appoint a technical lead or BIM coordinator to lead the process.
Without this alignment, models can be developed with different assumptions, making subsequent analysis more difficult.
2. Importing models into a common environment
All the models from the disciplines involved are integrated into one. CDE (Common Data Environment) common data environment.
Software such as Navisworks, Solibri, Revit, or BIMcollab are used to visualize and overlay the models.
This integration allows one to see the work as a whole, and not in disconnected parts.
3. Clash Detection
In this step, the software automatically scans for physical obstructions, for example, when a structural element crosses a duct or a pipe encroaches on a circulation area.
Each conflict is identified, recorded, and classified according to its severity.
4. Registration and prioritization of conflicts
After identifying the problems, it is necessary to address them logically and strategically. Not every conflict requires immediate action: some are simple to resolve, while others demand a project review.
Therefore, conflicts are categorized by criticality: high, medium or low. This prioritization helps with team organization and meeting deadlines.
5. Collaborative corrections to the models
Based on the conflicts recorded, the responsible teams make the necessary adjustments. This is a step in active collaboration. Everyone involved needs to review, discuss, and decide together on the best solutions.
Here, BIM shines: it allows changes to be tested in real time, with visible and documented impacts.
6. Final approval and documentation
After the revisions, the model is updated, verified again, and approved to move forward. It is important to document all changes made, recording the traceability of decisions.
This final, compatible model will be used in the following stages: planning, budgeting, and construction.

Most common compatibility errors (and how to avoid them)
Even with BIM support, some operational errors still compromise the compatibility results. Here are the main ones:
Working with outdated models
A common mistake is using old versions of files. This generates conflicts that have already been resolved or ignores new interferences.
Avoid this: Use a CDE with version control and a coordinator to validate the files before analysis.
Do not standardize the models.
When each discipline models in a different way, with different coding and levels of detail, the software may not correctly identify the conflicts.
Avoid this: Define clear modeling standards and a naming guide from the outset.
Ignoring minor conflicts
Some believe that only major conflicts deserve attention. But small, accumulated mistakes cause great harm.
Avoid this: Treat every intervention seriously and document everything, even the simplest adjustments.
Lack of coordination
Without someone responsible for centralizing information, the compatibility process becomes a game of passing the buck.
Avoid this: have a BIM coordinator with technical expertise and the ability to coordinate with teams.
To make compatible is to build intelligently.
BIM project coordination is a step that anticipates problems, reduces costs, increases productivity, and ensures greater safety for the project and the construction.
She transforms BIM into a true ally for strategic planning.
At Cadbim, we believe that compatibility goes beyond simply combining models: it's about creating a collaborative culture with clear processes, practical solutions, and continuous support.
