PAS 1192-2:20131 ScopeThis Publically Available Specification (PAS) specifiesrequirements for achieving building informationmodelling (BIM) Level 2 – see Figure 1 and Table 1.The requirements within this PAS build on the existingcode of practice for the collaborative productionof architectural, engineering and constructioninformation, defined within BS 1192:2007.PAS 1192-2 focuses specifically on project delivery,where the majority of graphical data, non-graphicaldata and documents, known collectively as the projectinformation model (PIM), are accumulated fromdesign and construction activities.The intended audience for this PAS includesorganizations and individuals responsible for theprocurement, design, construction, delivery, operationand maintenance of buildings and infrastructure assets.Where possible, generic language has been used, butwhere necessary, specific definitions are in Clause 3.Commencing at the point of assessment (for existingassets) or statement of need (for new assets) andprogressively working through the various stages of theinformation delivery cycle, the requirements within thisPAS culminate with the delivery of the as-constructedasset information model (AIM). This is handed over tothe employer by the supplier once the PIM has beenverified against what has been constructed.© The British Standards Institution 2013 1
