BSI has published new guidance effective from 31 July 2014. PAS 1192-3 focuses on asset management. It's a companion to PAS 1192-2 on information management to support delivery of BIM Level 2.
It covers creating an asset information model; exchanging asset information with a project information model; recording information; using the model to support organizational requirements; reviewing the model as assets change and holding the model as a resource.
It does not deal with data content but gives a broad idea of what that might be. Neither does it specify asset information requirements. These are likely to be very specific to an organization.
The PAS states it is for use (i) by those responsible for the operation, maintenance and strategic management of assets; (ii) those transferring date from a project information model to asset information model; (iii) for those involved in exchanging data throughout the life of an asset.
It's worth spending time reviewing it.
