BIM: Enabling Sustainability and Asset Management through Knowledge Management

The disadvantages of built asset information modelling.

Disadvantages of BIM	Description
A single detailed model	BIM does not allow alternative design options or the managing of ‘‘what if’’ scenarios.
Interoperability	One software standard needed. Often firms have their own software; for BIM, every firm needs to change to the same software standard throughout the entire built asset process.
Added work for the designer	For BIM to work ‘‘optima forma’’, the designer needs to create the ‘‘rich’’ model. They will be drawing something that will form the foundations of a complete system analysis. This means a lot more work for the designer.
The size and complexity of BIM	The large size of BIM will require different means of data sharing, and real time access into the database will require broadband internet access, together with security of data being worked on.
Trade Practices implications	While some countries have mandated BIM, this is unlikely to occur in Australia, if this restricted trade.
