What is BIM?

We live in a world that is built on standards that help us drive innovation and increase productivity. On a more rudimentary level they make our lives easier. These range from interoperability standards that ensure our bank and debit cards fit into any ATM in the world, to the standards in food labelling that let us clearly understand the nutritional value of our food.

In the context of the digital world in which we now live, standards allow us to create, use and maintain information in an efficient way. They not only encourage best practice, they offer a means to achieve real improvements. Sharing construction information, drawings, specifications and schedules in an agreed and consistent manner can bring about savings in cost and reduce waste.

House Keeping

The UK Government has a clear BIM strategy that is focused on the production, exchange and use of data and information as the main means of delivering improved construction performance and savings. We need to safeguard against information loss and to start collecting, producing, submitting and retrieving information digitally. Digital information is currently manually manipulated to suit different contexts, requirements and exchanges. We need to enable automated information exchange with improved analysis capabilities and compliance checking. In this emerging BIM environment content needs to be open, accessible, standardised, structured and controlled using an understood vocabulary. To achieve this we require standards around data, process and terms. Where is information kept, who owns it and what does it represent? We need to consider access control, who can get to the information, who can manipulate it, and how we record it? Also, how do we know who's accessed it?

Supporting the Government's Strategy

When we went from the drawing board to CAD, BS 1192 (first published in 1998) provided a guide for the structuring and exchange of CAD data. Revised in 2007 and given a new title of Collaborative Production of Architectural Engineering and Construction Information, the standard gave more emphasis on collaboration so that data can be effectively reused. It promoted the avoidance of wasteful activities such as waiting and searching for information, over-production of information with no defined use, over-processing of information simply because technology allowed it, and defects caused by poor co-ordination across the graphical and non-graphical data set which will require rework.

All standards need to be reviewed and updated to reflect current practice and future direction. The B/555 Committee (Construction design, modelling and data exchange) set out within its roadmap the maturity sequence that the standards will go through from Level 0 to Level 3 BIM in accordance with the UK Government's BIM Maturity model. of the need to understand future use of information and what happens downstream led to the creation of a Publically Available Specification (PAS). This document is PAS 1192-2:2013 Specification for information management for the capital/delivery phase of construction projects using building information modelling, and it is accompanied by BIM: A standard framework and guide to BS 1192. The guide document covers the processes and procedures required for public project delivery, such as the BIM Protocol, a digital plan of work, employees information requirements and COBie. It is one of a number of documents supporting the Government's strategic objectives. BS 1192 is at the core of PAS 1192-2:2013 and both support and underpin the means of achieving Level 2 BIM compliance. PAS 1192-2 was sponsored by the Construction Industry Council and is free to download. The benefit of using the PAS process is that a document can be developed and put to the industry in a very short space of time.

PAS 1192-3

BSI released PAS 1192-3 Specification for information management for the operational phase of construction projects using building information modelling for public consultation which closed early in December 2013. This is a partner document to PAS 1192-2. While Part 2 focuses on the delivery phase of projects, this new document focuses on the operational phase of assets, being about the availability, integrity and transfer of data and information during this phase.

The document specifies how information from the Project Information Model (PIM) is transferred to the Assets Information Model (AIM) or how an AIM is created for an existing asset. Of equal importance is how information is then retrieved and passed on to an existing enterprise system such as a data base. While it is not explicit in what data is to be covered it does cross refer to broad headings and documents which will define data content.

Unlike Part 2, which follows a clear sequence through the project stages, Part 3 describes both a mixture of planned and unplanned events in the life of an asset that could happen in any order between the point of handover and disposal.

Who Is PAS 1192-3 For?

It is intended for those responsible for the management of assets, including their operation, maintenance and strategic management. The document acknowledges that despite similarities in the nature of asset being managed, there are differences between asset management and facilities management, not only in terms of the standards or specification that they use but also in the use of language and terms. While facilities management has a distinction between hard FM and soft FM, PAS 1192-3 uses the term 'Asset' and 'Asset management' to refer to physically related requirements.

In order to get the correct information from the outset details need to be recorded within an Asset Information Requirements (AIR). The AIR then will become or form part of the Employer's Information Requirements (EIR).

PAS 1192-3 is closely related to PAS 55-1 and PAS 55-2, which provide the overarching framework for adoption and implementation of PAS 1192-2 and PAS 1192-3, both of which support Level 2 BIM and apply to building and infrastructure. Other documents referenced within the PAS include:

  • ISO/IEC 27001:2013 Information technology — Security techniques — Information security management systems — Requirements
  • BS 8210:2012 Guide to facilities maintenance management
  • BS 8587:2012 Guide to facility information management

One of the key messages from the Government is to 'produce the right information, at the right time, at the right level of detail and definition'. As we approach 2016 (the Level 2 BIM requirement date) this new standard will take us a step closer to achieving the aims set out in the UK Government Construction Strategy.
