The government's decision to require that all suppliers involved in public sector construction projects use Building Information Modelling (BIM) tools and techniques by 2016 makes sense. This should help drive improvements in value and performance, whilst supporting environmental commitments by facilitating a more integrated approach to design, construction, and facilities management.

However, misinformation is rife. BIM is not just about 3D data but about creating a holistic information resource that also includes 2D data sources, documents, spreadsheets, and more. Nor is BIM best realised by a single, lowest-common-denominator data model imposed on every organisation in the supply chain. BIM is a business process, not a technology.

The key to realising the compelling BIM vision is simply ensuring that every individual and organisation has rapid access to the in-depth information required to drive effective cooperation and collaboration at every stage of the design, build, and operate lifecycle.

DRIVING VALUE
Given the sustained economic challenges being experienced across the building sector, every organisation is looking for better value from building projects. For a cash-strapped government looking at ways of reinvigorating the economy and eliminating waste, there is a pressing need to realise objectives, avoid over-runs in both cost and time and ensure the end infrastructure asset truly reflects requirements.

The government's commitment to BIM is about driving better value from capital investment and realising a 20% reduction in lifetime costs. It is also about changing the culture between the client and the rest of the supply chain, replacing the traditional, rather adversarial business practices with a collaborative approach that should also drive innovation.

The key to realising this vision is to create simple, effective cooperation among the design, construction and operations aspects of the infrastructure lifecycle. Overcoming these traditional silos provides a chance to reduce duplication, minimise errors, streamline processes and facilitate collaboration.

Commitment to BIM is growing fast. However, it is apparent that there is considerable confusion about what the adoption of BIM actually means to organisations at different stages of the supply chain. While the majority of new bids now demand some level of BIM compliance, requirements are often opaque at best.

INFORMATION SHARING VIA INFORMATION MOBILITY
As a result, there is a real risk that companies will either impose costly technology choices on partner organisations across the building supply chain, from mechanical engineers to contractors, or be coerced into making technology choices that fail to reflect other key business requirements simply to achieve BIM compliance. Sadly, this will be done in place of approaches that incorporate coordinated technologies appropriate for the varied roles and tasks.

Unfortunately, the message being disseminated across the industry is that BIM is a design-led initiative that is dependent upon construction companies adopting the same 3D tools as their design partners (and vice versa) to create a single source of project information. This is untrue at many levels - from the 3D assumption to the single data source approach. The single data model is not only expensive and hard to achieve, it also doesn't work. Organisations that have tried this model have quickly discovered that information becomes federated because of the many disciplines involved, and the single model descends into multiple uncontrolled data silos.

Let's set the record straight: BIM, when done correctly, is about information sharing enabled by information mobility (across engineering disciplines and the infrastructure lifecycle). It provides contractors and owner operators with access to key design data that can be used to transform effectiveness throughout the construction and operations processes. Yes, it drives better use of 3D across the industry, but not only 3D. 2D data remains important, as does information held in documents, spreadsheets, and other databases, all of which contribute to a holistic BIM approach.

ASSET MODEL
BIM is, in fact, about finding the best way to share and integrate information from many sources, authors and systems in a managed, secure and trusted manner. It is ultimately about creating an asset model from day one that can be used consistently throughout the project to drive efficiencies and improve collaboration.
