An Overview Of Clash Detection CA

By Sarah Gibson


Any construction consists of a number of sections. Each section requires specific expertise to handle. Current modeling technologies allow different actors to come up with various models for their tasks. This is later brought together to form a larger model that represents an entire construction. For this reason, different errors arising from integration are inevitable. Clash detection CA at an early stage is vital for a smooth development process. To understand this concept, read through the following summary.

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.

The nature of conflict brings about two types of clatters namely hard and soft. Hard clatter is a situation whereby two different building components occupy the same position. Soft clatter happens when two elements occupy a similar space but one of them breach the buffer zone of the other. A good example of the first type is when piping passes through a steel beam. If an air conditioner is squeezed so that there is insufficient space to maintain, access or safety is compromised, such as an example of soft conflict.

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.

The future for BIM technique of identifying and solving issues early is likely to be better. Where stakeholders worked on projects independently, they will now be required to operate on a single mock-up. Consequently, a number of errors will be reduced as the need for assimilation of various models is eliminated.

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.
