Delivering PAS 1192

Download as PDF

Paul Oakley BA(Hons) Dip Arch RIBA.


PAS 1192 defines the specification from the UK Government regarding the delivery of BIM. It is intended to be adopted for both public and private procurement first in the UK and then worldwide. This specification dictates the structuring of design data through the use of various British standards such as BS1192:2007, BS8541 parts 1 to 4, etc… as well as the delivery of design data in new formats such as COBie. But what does this actually mean for the BIM modeller and the Design teams?
This paper explores the impact of PAS 1192 on the software user producing BIM data. They are now authoring data not just for the production of drawings, but specified structured data that can aid the construction process and the delivery of life cycle management, whilst also having to comply with British Standards.
The paper explores how BS1192:2007 CAD terms, such as containers are translated into BIM software terminology. It will also provide guidance on how BS8541 impacts content creation and parameter definitions, as well as exploring how this is translated into data structures and the implications of this for exporting data in formats such as COBie.
The paper will review how projects should be structured in order to work within the enhanced common data environment (CDE) defined with PAS 1192. It will also review the impact of the “status” and “purpose” requirements on those delivering data and the rigor and roles that this will create.
PAS 1192 and the defined British standards define a structured process for the creation and delivery of BIM data. The process must be understood; followed; delivered and authenticated for the savings identified by the UK Government to be achieved. To Quote a phrase "This is not just about BIM, but it’s all about BIM…"
