The manual approach of coordinating 2D drawings, trying to identify conflicts among graphical representations of the construction appearing in countless of documents produced by several disciplines and trades, is time consuming and prone to human errors.

BIM Clash detection process has the ability to automatically identify elements taking the same place in the digital environment following predefined rules.

This process leads to an error-free representation of the construction in the digital environment, and thus builds confidence and mitigates risk in actual construction.

EB/Architects have developed a clash detection strategy that can be applied in very large projects, where number of clashes can often blow up. It does not involve the typical clash matrix, but a linear mapping of clash detection data, using a customized 'tree' of tests, beginning from the most abstract – top level test – and followed by multiple sub-tests, created as needed, in order to analyze, understand and resolve critical issues.

The full tree of tests provides overview of all clash tests’ results, even for those deemed as 'non-critical', for a process which is transparent and leaves no element excluded from the testing procedure, for a streamlined workflow towards a 'zero critical clashes' project.

Spatial Coordination however is more than Clash Detection: As part of any BIM Strategy, includes Quality Controls, interdisciplinary Design Reviews, and BIM generated Coordinated Documentation deliverables, that combine information originated from all disciplines and trades to a single 3-Dimensional environment. These 3D documents, that are not Architectural, Structural or MEP, but a combination of all, are complete with all necessary data, such as coordinates, size data, levels, and dimensions that are useful to the design and construction team.
