An Outline 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.

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.

Before stakeholders think of solving issues, they should consider avoidance. As a matter of fact, it is cheaper and less time-consuming. There are a number of ways to help them in this. First, it is advisable to have standard procedures followed by each team member. Secondly, coordination of activities should follow a certain protocol as indicated in Employers Information Requirements. This will prevent clashes among team members.

Prevention minimizes problem instances. This is to say, even though avoidance techniques are put in place prior, mistakes can still happen. It is automatic in Building Information Modelling shortened as BIM. Since it is dependent on software, a designer needs to scan through a project in the course of designing. The same applies when mock-ups are combined. Initially, team members would produce drawings on specific check spots to confirm whether there is compatibility.

Once a clatter is noticed, what follows is resolving. Resolution is based on the kind of error. When a conflict is noted, an entire model is scanned to bring out other similar instances. Normally, when a single instance is solved, the solution is duplicated in others. It is vital to review and cancel conflicts early during the design phase.

Level two BIM is effective in detecting errors. Notably, the future of this technology is even better. Level three BIM will eliminate the need for having different team members coming up with individual models. Instead, it will provide a single space to work on one archetypal.

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