SPATIAL CONFLICT CHECKING

As previously described, coordination of various trades within the construction documents and on the building site can be complex. The architect is generally responsible for such coordination during design phases, and would circulate two-dimensional design information required for engineers and technical consultants to perform their design services. Conventional documentation by various consultants, such as a mechanical engineer, would not necessarily be transmitted to another, such as a structural consultant. This would at times lead to physical conflicts between building components during construction. For instance, a duct might have been designed to be routed through the same physical space as a structural beam, causing change orders on the project site and revisions to both the mechanical and structural documents. This cause and effect situation could also lead to revisions to other work including architectural and plumbing. Recall that the various trades – who execute the work done virtually by various consultants (structural, plumbing, etc) – are scheduled on project sites at different times, structural steel would be erected prior to plumbing risers, so virtual coordination of the construction sequence within an information model could prevent change orders in the field.

Within the information modelling environment, the designer can query specific assemblies and generate bills of quantities that can be linked to database or web-based cost information.
