South East #BIM Hub South – Session No. 7 @sebimhubsouth

Review of South BIM Hub No. 7 – BIM Implementation / 8 Pillars of BIM


The first meeting of the South BIM hub in 2015 was held on the 6th February in Hampshire County Council’s Ashburton Hall. A change in room location was required due to the 80 people in attendance, an excellent turn out of consultants and businesses interested in Building Information Modelling. The subject of this session was to examine what BIM Level 2 is now that the documentation is nearly complete; described as the ‘Eight Pillars of BIM’.

The session started with an update from Mike Turpin who explained that PAS 1192-5: Specification for security-minded building information management, digital built environments and smart asset management has been released in draft for comments. Additionally the NBS Level 2 BIM Toolkit was previewed at “ThinkBIM” on the 4th November with next update due on April 1st and released shortly after.

Guest speaker Richard Lane, who works as part of the Government’s BIM Task Group, provided an update on recent developments and what it means to work together collaboratively, expanding on BIM as;

B – Building a consistent, collaborative industry, with clear and open communication

I – Information of high-quality is procured to support business outcomes

M – Modelling the design increases efficiency, enabling simulation and analysis

This gave an excellent position to then discuss BIM Level 2 – the 8 Pillars of BIM. From 2016 all Centrally procured Government projects will require BIM Level 2 and the South BIM Hub was keen to investigate what this means and use the expertise within the room to expand on each of the pillars. The 8 Pillars of BIM are:

PAS1192:2            PAS1192:3            BS1192:4               PAS1192:5            CIC BIM Protocol

Government Soft Landings                Digital Plan of Works                          Classification

The session was very ambitious to cover all of the BIM Level 2 documentation in one workshop, however it did reveal the complexity of understanding the full Level 2 requirements and will allow for future sessions to focus on specific documents. The number of people and range of backgrounds present helped to break down the documents in one session. It would appear that much more work is required to ensure that design teams are ready to respond to government requirements. In particular clients will need to understand what they are asking for when they use this documentation.

Below is a summary of the responses to the 8 documents:

PAS 1192-2 – Specification for information management for the capital/delivery phase of construction projects using building information modelling

  • Document is a roadmap of BIM processes
  • Applies to everyone involved in a project
  • Relies on BS1192:2007 Collaborative Production of Architectural, Engineering and Construction Information
  • Good as a single point of Reference for BIM Level 2
  • Was not considered clear and easy to understand – requires a concise summary
  • Common Data Environment is vital to BIM process
  • Document is vital to BIM!

PAS 1192-3 Specification for information management for the operational phase of assets using building information modelling (BIM)

  • Defines a framework of what is required post construction and Asset requirements
  • Document reveals that Asset management conversations need to be brought forward into design and construct phases
  • Used by clients to inform Employer Information Requirements (EIRs). This means that FM teams should be involved
  • Document was criticised for lots of jargon without giving detail
  • Stimulates questions and things to look at rather than answering them
  • Relies on PAS 55 / ISO 5500

BS1192-4 Collaborative production of information Part 4: Fulfilling employers information exchange requirements using COBie – Code of practice

  • Structured asset information output for a scheme
  • Data from design to management, full life cycle embedded into process
  • Difficult to relate items to codes of systems for COBie
  • Relies on all other PAS documents
  • COBie is lowest denominator for asset information (i.e. an Excel spreadsheet)
  • It does give structured information
  • But is complex and difficult to understand
  • It was questioned whether it get widely adopted?

PAS 1192:5 Specification for security-minded building information management, digital built environments and smart asset management” is currently in development

  • This is a pragmatic, holistic, risk management document primarily looking at security
  • Not just about protection of the digital data
  • Looks at systems as well as people process and facilities
  • It is for everyone (covers nuclear and data centres down to small projects with no specific security needs)
  • Makes people think about security even if they are not working on big secure conscious projects
  • References other pillars especially part PAS 1192-2 and 3
  • PAS 1192-2 & 3 now need to be revised to reference PAS 1192-5
  • Need to manage security and be aware of neighbouring security
  • BIM is good for good people but could also be good for ‘bad’ people if data not controlled and secure
  • Scalable for projects

CIC BIM Protocol

  • Contractual definition of roles and responsibilities
  • Addendum to existing contract forms
  • Works as a template and needs sections filled in
  • Attached to any client BIM contract (for design team)
  • Not widely used within the room to date

Government Soft Landings

  • Directional document from constructional design to operation
  • Gives aims of what should be done but doesn’t say how
  • It is about engaging client in design and construction stages of project to secure positive outcomes
  • Making sure client gets benefit from the BIM process
  • Need to engage FM / maintenance earlier on
  • Being put into a BS8536 Facility Management Briefing – Code of Practice

Digital Plan of Works (DPoW)

  • Work plan for all involved in project defining who should do what, when and at what stage
  • Clear map of project information
  • For models and information
  • It will validate info is there but not validate if it is right.
  • FREE tool!
  • Links to RIBA DPoW


  • Based on Uniclass 2
  • New classification system for BIM information
  • Dictionary for BIM to enable easy filing and sorting of information
  • Classification for all disciplines
