A Synopsis Of Clash Detection CA

By Sarah Gibson


The process of coming up with a complex building requires a number of stakeholders to come together and carry out various tasks that culminate into a final project. The modern construction industry has improved greatly. Instead of coming up with architectural designs on a piece of paper, developers rely on Building Information Model or BIM. The advantage of using this is that clash detection CA happens early enough. Below is an overview of the error discovery process.

To start with, people need to understand what errors in building means. When designing a project, some components could occupy the same space or squeeze each other. Such incidences are referred to as conflicts. These incidents majorly occur during assimilation of models from various stakeholders. To come up with a complete project, numerous stakeholders such as electrical, mechanical and environmental specialists have to come up with individual replicas representing specific functionalities. These are later assimilated into one mock-up. Problems arise due to varying makeup of each model.

There are numerous types of conflicts. The most common one is hard clutter. This occurs when two elements occupy a similar space. For instance, there could be pipework running through a steel beam. If these errors are detected during construction, it might be very challenging to fix them. Another type is soft conflict. It occurs when a component is denied geometric buffering it needs. An example of this is where an air conditioning system has limited space for access, maintenance or safety due to a close beam.

Someone would wonder whether it is possible to avoid these conflicts while various replicas have to be integrated. With BIM, this is possible. Most significantly, designers must document a set of standard processes to be followed by all stakeholders in an execution plan for BIM. Secondly, to avoid conflict among stakeholders, there should be a contract document signed by each one of them.

It is inevitable to have errors no matter how much prevention techniques are put in place. How errors would be detected traditionally is different from how it is done in BIM methodology. Initially, team members would work on separate drawings then tracing documents would be produced during organized checkpoints. However, BIM depends on a set of software and automated tools that vary depending on what task an individual is working on.

For BIM models, problem reviews are very comprehensive. Reports will indicate where a problem is located as well as the type of issue. Once this is done, a solution will be implemented by specific team members depending on which departments are affected. Most issues are often related such that if an underlying condition is solved, the rest get into place.

As buildings become more sophisticated, it is possible that BIM tools will also improve. This way, the process of detecting clashes will become easier and more effective. A major improvement that is being foreseen is a case where various stakeholders will be working on a single model rather than different pieces that need re-integration. Eventually, a number of issues will greatly be reduced.

To wind up, a building project is complex. Before contractors get down on actual construction, they have to design first. Issues should be detected and solved in the design stage to minimize major disruptions when the building begins.
