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.

A defect in a construction is a state whereby various components are not coordinated as they should leading to clattering. BIM enables stakeholders to spot and reverse these misalignment while designing. The main cause of misalignment is the need to combine different models built by various stakeholders. Normally, tasks are divided among team members such as architects, mechanical, environmental and electrical engineers. Typically, each of these develops their own models which are later combined to make an entire project. Due to the variance in documentation and elements, there is no doubt that some components will conflict after integration.

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.

It is said that prevention is better than cure. This concept also applies to the building. Before beginning a task, stakeholders should put in place mechanisms to prevent basic problems. For example, there should be a document to coordinate the work of various team members, how and when each should deliver. Additionally, each member should be guided by a set of predefined procedures.

These avoidance mechanisms do not guarantee that errors will not occur. Traditionally, developers would make different drawings during co-ordination checkpoints to ascertain compatibility. For BIM technique, designers have specific software and assimilation tools to check for conflicts in their personal as well as combined models. Notably, some soft errors can be ignored.

An automatic scan is run through to discover where errors are located as well as the nature of each. Usually, one type of conflict is duplicated several times. For instance, if one pipe clashes with several beams, the scan will show five conflicts. Essentially, when the placement of this pipe is handled, all these clatters are solved simultaneously.

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.

BIM is a useful building tool. Most significantly, it helps engineers to detect and correct clatters during the design stage.
