RIBA have released a "BIM Overlay" to the RIBA Plan of Work. 

Recognising that BIM (Building Information Modelling) is transforming modes of working in the construction industry and that there will eventually come a point where BIM is widely accepted and used, the BIM Overlay provides clear guidance about which BIM-related activities are required at each stage of the RIBA Plan of Work to successfully design and deliver projects in a BIM environment.

The BIM Overlay builds upon the Green Overlay issued in November 2011, and both are evidence of the preparatory work being undertaken with a view to a comprehensive review of the RIBA Plan of Work due to take place in 2012-2013.

The RIBA BIM Overlay can be found here.
