CD March 2015 - Bentley presentation about current BIM thinking
- 1. Current industry BIM thinking Iain Miskimmin BIM Level 2 COBie BS119 2 Uniclass BIM AD4
- 3. Construction Strategy Construction Strategy “The Government Construction Strategy was published by the Cabinet office on 31 May 2011. The report announced the Governments intention to require collaborative 3D BIM (with all project and asset information, documentation and data being electronic) on its projects by 2016.”
- 4. Government Soft Landings (GSL) • Early engagement of the end user • GSL champion per project • Clear targets for: • social outcomes • economic outcomes • environmental outcomes • Focusing on; commissioning, handover and training partnerships • Requiring post occupancy evaluation to asses performance for at least three years.

- 7. BIM task group BIM Task group “The Building Information Modelling (BIM) Task Group are supporting and helping deliver the objectives of the Government Construction Strategy and the requirement to strengthen the public sector’s capability in BIM implementation with the aim that all central government departments will be adopting, as a minimum, collaborative Level 2 BIM by 2016.
- 8. Digital Plan of Works dPoW “The purpose of this document is to clearly document the concepts and detail of the management of built asset data derived from the process of building and managing building information models”
- 9. Design Construct Test and Commission Operate Maintain Business outcomes Create an end to end BIM process for an asset Asset Lifecycle NN7654321 (Part of a) “detailed programme of measures Government will take that will reduce costs by up to 20% by the end of this parliament”
- 10. Asset – Generic term to represent: •A physical thing that delivers services or supporting services e.g. a structure, paved area or lighting etc. The structure asset example is also made up of multiple assets forming a functional group. We record assets down to the level we would expect to maintain them e.g: a Stair and not individual steps and landings a Window and not the frame, glass and locking mechanisms a Pump and not pump motor bearing What is an Asset?
- 11. Functional Grouping Function – To take Road A over Road B Pile Retaining wall Safety barrier Beams Decking Piers Surface course etc.
- 12. A Complex, Facility, Entity & Elemen Complex Facility Entity Element
- 13. Linking the physical and virtual
- 14. The Asset Tag Asset Tag Equipment Serial Number • Tag – the specific duty of an Asset •e.g. Drainage Pump 1 • Equipment – the actual physical item performing the duty of a Tag •e.g. Acme Model B Pump • Serial – an individual instance of Equipment or Batch •e.g. 12345 • Functional Unit – a collection of Tags that work together as a system •e.g. Drainage Pumping Station Functional Unit Serial Number Equipment Asset Tag Asset Tag Label Equipment/Serial Label Physical Virtual

- 20. BS1192:2007 “This standard establishes the methodology for managing the production, distribution and quality of construction information, including that generated by CAD systems, using a disciplined process for collaboration and a specified naming policy.”
- 21. BS, PAS, Parts 2,3 and 4? PAS 1192-2 specifies requirements for achieving building information modelling (BIM) Level 2 PAS 1192-3 focuses on the operational phase of assets irrespective of whether these were commissioned through direct capital works, acquired through transfer of ownership or already existed in an asset portfolio BS 1192-4 defines the collaborative Production of Architectural, Engineering and Construction Information Part 4 – Client information requirements (COBie) BS1192:2007 Established the methodology for managing the production, distribution and quality of construction information, including that generated by CAD systems, using a disciplined process for collaboration and a specified naming policy.”
- 22. COBie Love it or Hate it..... “One of the key Level 2 requirements is the exchange standard of COBie and PDF, as well as copies of the native files.”

- 26. IADD4UK – part of the AIR “Asset Data Dictionary Definition Documents (AD4) - clarifies what each individual Class or Function represents, how/what attributes are to be populated and provides examples” • Defines types of assets • The functions and classes that relate to them • Attributes relevant to them • What an Attribute means e.g. Length/ Depth etc • Is one of the building blocks for the Asset Information Requirements

- 30. So what is BIM? “Every part of the supply chain has a different piece of the information puzzle that goes together to answer the clients requirements. Each piece, no matter how small, is important because without it the puzzle is incomplete.”

Editor's Notes
- COBie... What happens if you type in COBie into Google? You get a lovely young lady called Cobie Smulders, however, that’s not what we are here for. COBie stands for “Construction Operations Building Information Exchange” and like the BIM acronym it suffers from having the word building in the title and is currently not fit for infrastructure with an inability to handle linear assets. However the government has mandated that to achieve level 2 BIM you will need to both receive and deliver information in COBie format. It scares most people, who see it as an overly complicated spreadsheet of mind boggling proportions. However you need to think of it simply as a suitcase that delivers information from one place to another. Be that a system, company or project. Love it or Hate it, it is a requirement that all information is transferred in this manner.
