What is PAS 1192 part 2?
PAS stands for Publically Available Specification.
It enables an emerging standard to be rapidly developed in response to an immediate industry
need.
In this case PAS 1192 part 2 was developed to support BIM adoption in the United Kingdom.
It provides a consistent industry-wide framework for collaborative working and information
management in a BIM Level 2 environment.
PAS 1192 part 2 evolved from the British Standard BS 1192, published in 2007.
That document set out the code of practice for the collaborative production of building
project information.
BS 1192 is effectively part 1 of the PAS 1192 part 2 publication.
It is still relevant today.
PAS 1192 part 2 focuses on information that is originated, exchanged or managed in a BIM
format.
BS 1192 covers all other areas of project information management.
So why the need for these documents?
Well producing information that is unnecessary, confusing, not structured properly, poorly
co-ordinated and/or difficult to find has been found to add around 20-25% onto the cost
of delivering our built environment.
Having greater integrity and taking more care over the way we structure our data can eradicate
this waste from the process.
Greater clarity will give us improved levels of efficiency.
Leading to time and cost savings.
When we focus our energies on the important parts of the process, rather than on searching
for or interpreting information, we become more effective.
This can ultimately improve the quality of the built environment that we all live our
lives in.
The important point here is that this approach requires more discipline, NOT more work.
So what does the PAS 1192 framework look like?
Well it’s aligned to the latest RIBA work stages and recognises information increasing
through the project delivery period to the point of handing over the new asset to the
Customer and end user.
At this point, with the information at its richest, data is passed to the Customer and
end user to enable them to operate their new asset.
Collectively this data is known as an information model, though it must be noted that a physical
3D model is only one part.
BIM is a project delivery process, not just 3D modelling.
Data generated in the project delivery phase sits within the ‘Project Information Model’.
Once handed over and in operation, this is known as the ‘Asset Information Model’.
The model be can be continually enriched during the operational phase to assist in managing
the asset.
PAS 1192 part 2 covers the project delivery phase, stages 1-6 only.
The operational phase of a building’s life cycle is covered by a separate PAS document
following on from PAS 1192 part 2, cleverly termed PAS 1192 part 3.
All information must be exchanged in a ‘Common Data Environment’ accessible by the whole
project team.
PAS 1192 part 2 sets out clear protocols for the authoring and sharing of information in
a common data environment once it is ready to be published.
Key documentation is required throughout the project lifecycle to support the process.
This starts at the outset of capital expenditure on an asset with the Employers Information
Requirements or EIR.
Here the strategy for meeting the Customer’s need is determined.
The EIR sets out the information that a Customer will require to run their new facility and
to make decisions about its development during the project delivery process.
With this strategy in place, procurement can occur and the BIM execution plan, based on
the EIR can be created.
The execution plan explains how the information modelling aspects of the project will be carried
out and is a key document for all parties.
Following the process of Contract Award, the Master Information Delivery Plan (MIDP) is
produced.
This sets out the information is to be prepared, who needs to prepare it and the protocols
and procedures for its production and release.
This can only be developed from the BIM execution plan and EIR.
It is essential that it is on place prior to that start of the design process.
From this firm foundation, the project team can mobilise and commence the project delivery
process, building their information model in full alignment with the Customer’s needs
and requirements.
At the point of handover, operating expenditure commences and the asset management phase begins.
This period is governed by PAS 1192 part 3 as we discussed earlier.
By possessing a data rich information model, the Customer and end user are able to assess
the performance of their built asset and wider property estate over time.
This allows them to be better informed when renewing their assets and commencing the delivery
process again in the future.
The cycle is supported by continual information exchange between the project team and key
Customer decision points throughout.
PAS 1192 part 2 is a key document in managing Level 2 BIM projects.
