What / how?
Independent analysis, quick and cost-effective identification of inconsistencies and missing details after the plans of the disciplines appear in the BIM model.
When to use them?
It would increase the sense of security if an independent examination confirmed that clashes – which in most cases cause additional costs and slippage – were eliminated (e.g. whether maintenance routes were.
What is a crash test?
BIM-based clash detection is a technique that detects discrepancies between different models and can therefore speed up the design process and the construction as a whole. With BIM, designers as well as contractors can avoid multiple revisions of designs, which can save a significant amount of time and cost for the project.
Collision analysis can automatically identify design errors and problems, helping designers, builders, various engineering professionals and the contractor. During the process, we can determine which elements of the building are in conflict with each other, paying particular attention to walls, mechanical solutions or any geometric object.
The benefits of collision analysis:
- It allows the structural stability of the building to be assessed.
- It can help to avoid construction delays.
- It minimises the chances of human error.
- Helps to ensure that the construction site meets all regulations.
What types of collision should be expected?
- Soft clash: when the model does not provide enough space for the element, which can cause safety risks and maintenance difficulties during construction.
- Hard clash: when two or more elements of the model intersect or are located in the same place. Such clashes can easily occur when designing cables or columns.
- Workflow clash: errors in the timing of execution, including problems with deliveries or arrivals.
