The capability of adding equipment data, and integrating that data with GIS information, turns BIM into a powerful tool.
The network of tunnels, pipes, and other underground utilities serving the 47 institutions of the Texas Medical Center in Houston complicates foundation work. By combining the proposed BIM of the Texas Children's Hospital Maternity Center with GIS data on subterranean structures, engineers pinpointed potential interferences. Portions of the foundation were redesigned to avoid conflicts before construction, rather than waiting to address them as a field problem.
Models can include information — for example, about the façade, the finishes for each interior wall and floor surface, and specific plumbing fixtures — that goes far beyond basic dimensions and locations of building elements.
