BIM & technical coordination
One digital model. Clashes found on a screen instead of on site, where they cost real money.
A clash between a duct and a beam costs almost nothing to fix in a model and a great deal to fix once the beam exists. That is the entire argument for modelling properly, and it is an argument about money rather than technology.
One model, held by one team, with architecture, structure and services in it. Not three models reconciled by email — that produces a fourth version nobody is responsible for.
Coordination is also a schedule instrument. The order in which packages are resolved decides when a contractor can actually start, so the model is sequenced against procurement rather than drawn to completion and handed over.
