PAS-And-BIM-LevelsThe adoption of Building Information Modelling throughout the UK means that there is a requirement for an adhered standard. However it can be confusing on what you need follow in order to work with your contractors/colleagues at a minimum of BIM Level 2.

I hear you say what is BIM Level 2?

Don't worry if you are just getting into BIM then you might not realise that there are a range of documents and key terms that will help you implement the approach within your projects and allow you to follow a consistent workflow.

So...Level 2 can basically be summed up as a managed 3D environment held in separate discipline 'BIM' tools with data attached.

However, there are a number of levels of BIM but Level 2 needs to be followed in order to be compliant with the 2016 UK Government BIM Strategy (yes I know I've mentioned this before but it is important). As it basically states that all publically-funded projects will require BIM so it will affect many of you.
As for the other levels they vary in the sophistication being used:

Level 0 – Unmanaged CAD, in 2D, with paper (or electronic paper) data exchange*.

Level 1 – Managed CAD in 2D or 3D format with a collaborative tool providing a common data environment with a standardised approach to data structure and format*.

Level 3 - A fully integrated and collaborative process enabled by 'web services' and compliant with emerging Industry Foundation Class (IFC) standards. With the potential to utilise 4D construction sequencing, 5D cost information and 6D project lifecycle management information*.

This is all well and good knowing what the varying levels of BIM are but if you don't know the clear standard or specification of Level 2 then you may supply the wrong information which can often add 20-25% to the cost of a project.

PAS1192-2To overcome this the UK Government have developed a number of documents to provide a consistent framework for those working in the world of BIM. The most widely used being PAS 11 92-2 which was developed in response to an industry need for a specification for information management for the capital/delivery phase of construction projects using building information modelling.

The document provides a consistent framework for collaborative working and helpful information management which allows those involved on a project to work from the same framework and in identical format. Aligned to the latest RIBA work stages the specification recognises information increases through the product delivery stages to the point of handing over to the customer and end user.

Preceding the still relevant BS 1192 which covers collaborative working and the other areas of information management. However PAS 1192-2 is limited to the project information stage including the brief, concept, definition, design, build & commission as well as the handover and closeout the framework is then taken over by the subsequent specification PAS 1192-3.

This focuses on the phase of building lifecycle including operation and use by the customer and end user.

The intended audience for this PAS (abbreviation of Publically Available Specification) includes businesses and those responsible for the procurement, design, construction, delivery, operation and maintenance of buildings and infrastructure assets.
