Construction projects usually take a lot of personnel to perfect the whole process. You have the architects, contractors, subcontractors, engineers, manufacturers, distributors, and so on and so forth. Therefore, it is not totally uncommon for some factors and elements to not mesh well with another. A particular data provided by, say, the architect, may clash with that of the engineer. Minute mistakes are just as unacceptable in this enterprise, but how can they be detected. Simply through clash detection in CA.
Building information modeling helps in streamlining the work of all these multidisciplinary personage. Its very useful, as well, in helping spot clashes in the project. It aims to do so early, so that the costs in resources, time, and logistics are lesser, cheaper, and less consuming. Just about anyone can see the value in that.
In construction and design terms, a clash happens when BIM components turn out not to be conflicting or just generally uncoordinated. The purpose of this Clash Detection, which well hereafter call CD just for the purpose of this discussion, is to spot these mistakes early and easily. Ideally, it has to be in the rectification of the design phase. In that way, it need not impinge on the practical work that's done on site.
Clashes occur as a matter of course. After all, we are talking about a whole range of disciplines that are not necessarily smooth and tight fitting when they come together. Each worker has his or her own model, from the architect to the mechanical, structural, and electrical engineer. You can only imagine the many data, files, and documents this takes, and when compiled, it might be deemed normal for some snippet to be a bit off.
A clash can come in many kinds and configuration. For example, it may be of the geometric type, in which the calculations and illustrations don't jibe well with each other, so that some lines pass or go through each other when they're not supposed to do so. Or perhaps its down on the schedule, such that when two or more elements coincide with each other.
There are also logistical clashes, wherein certain changes and updates have not been factored in, so that the results are naturally ill fitting. As already said, checking for clashes manually can be a tough line of job since even the minutest detail have to be taken to consideration. Its still possible to sift for them even without technical ways and means. However, its difficult and time consuming.
As per the literature in this topic, there are three kinds of clashes that are detectable by exiting technologies. They are the Hard, Soft, and Workflow varieties. With the first, that's when two elements or objects traverse each other. The second is more on the aforementioned geometric trope. And the last one has to do with scheduling abnormalities.
No matter how seemingly negligible, a lot of these abnormalities are quite costly to fix. That's why its imperative to pin them down during the planning process. The problem may not only be logistical but also legal and ethical. After all, the nub of the matter with every construction work is structural integrity, which in its turn contributes so much to safety, accordingly concretized in safety standards and building codes.
With effective clash detection software and tools, a lot of issues and problems, from structural deficiencies to timeline conflicts, can be done away with. The possibility for project errors go down, and models are completed during the design procedures, just as they're supposed to. Certainly, it does not only optimize time and resources, it also lowers costs and motivates the human resources, as it minimizes the negatives and maximizes the positives.
