International BIM Object Standard


The use of BIM (Building Information Modelling) in construction processes is increasing in New Zealand as it is internationally.  To maximise the potential value of BIM standards are needed to increase sharing of information and improve collaboration.

Following a consultation process in 2014, Masterspec, as an industry-owned organisation, worked with their sister organisation NATSPEC (Australia) . Workshop in April 2015, in Melbourne led to an agreement that the first step towards establishing National BIM Object Libraries would be to develop a joint Trans-Tasman BIM Object Standard.

To ensure that we align BIM practices internationally, it was decided that the existing United Kingdom NBS BIM Object Standard would be used as a starting point for the development of this standard.

An agreement was reached between NATSPEC, Masterspec, and the NBS (UK) to develop a core International BIM Object Standard that would be suitable for use within all three countries.
