PAS 1192-2 came into effect on 28 February 2013, with the intention that it will facilitate the adoption of BIM level 2 in projects. In this short article we give an overview of the content of the document and plans outlined for future development.
Publically Available specification – PAS 1192-2 – is published under license from British Standard Institution; its development was sponsored by the Construction Industry Council (CIC). It is one of the series of documents released by the government BIM Task Group as part of the legal framework for the adoption of BIM.
PAS 1192-2 builds on BS 1192:2007, which covers the collaborative production of architectural, engineering and construction information.
The publication of PAS 1192-2 is to achieve the goals set out in the government strategy report as it relates to Building Information Modelling (BIM) at level 2. It is perhaps important to remember that at Level 2 of BIM, the industry should be able to successfully address the problem of 'information that is inaccurate, incomplete and ambiguous', and thereby save up to 25% capital cost usually expended because of the exchange of low quality of information. PAS 1992-2 specifically offers guidance on information management processes in BIM projects. It is envisaged that when its processes are implemented in a project, all information (both in the BIM environment and conventional data formats) would be shared in a common collaborative data environment (CDE).
Summary of provisions
PAS 1192-2 can be accessed from the BIM Task group website .
The document may be summarised as follows:
- It sets a clear framework for information management by identifying documents to be produced (i.e. BIM Execution Plan, Project Information model etc.), when they are to be produced and what information sources they draw from as well as feed into. In doing this it defines the best practice for content of some important documents, for instance it lists over 20 items that should form the Employers Information Requirement at a minimum
- It gives the framework to plan the BIM information exchange aspect of a project, giving guidance on documents required at both pre and post contract stages and the need for supply chain engagement
- It emphasises the need for and sets out a framework to guide the definition of roles, responsibilities and authorities of project delivery team members
- It provides a visualisation of and guidelines to manage the CDE. Its framework includes a Work in Progress (WIP) area and rigorous review and approval process before information is transferred to the shared section of the data environment, it envisages that such review would include:
- Model suitability check
- SMP check
- Technical content check
- COBie completeness check
- Drawings extract checks along with any additional documentation that is shared as a co-ordinated package of information
- Approval by the task team manager.
- It also covers files and layer naming conventions as well as spatial co-ordination.
It emphasises that working in a collaborative environment would not necessarily require more work but would require discipline to attain a level of standardised processes required to deliver information in an organised and consistent manner. It sets out the following as the advantages of adopting a CDE:
- It ensures that ownership of information remains with the originator although it is shared and reused, and it can only be changed by the originator
- It reduces the time and cost associated with producing coordinated information
- It enables multiple uses of different information in various combinations.
Future development and conclusion
With a terms and definitions section and helpful diagrams, PAS 1192-2 brings to life the BIM information management process, highlighting the important points to note. It is the intention that another document, PAS 1192-3, will be published, which will offer guidance on the use of the Asset Information Model, and provide assistance on best practice in portfolio management for the life of the asset. The PAS is not a contract document but puts forward a standard that parties could incorporate into their projects.
