OK, a slightly tongue in cheek title, but an important point to consider. For many people BIM (Building Information Modelling) is a discipline that you utilise during a capital project – and whilst we are on that topic, any construction project can benefit from BIM, not just a ‘building’. This is the approach defined in PAS 1192-2. What may be missed is the fact that the benefits of BIM should come in three distinct phases:
- During activities to design, construct and hand over assets, BIM should avoid clashes between disciplines, loss of information or meaning when information is passed from one party to another etc. This is widely recognised as providing benefits of around 20% of the capital cost of a project
- Once handed over, BIM can provide on-going benefits whenever asset interventions are required as part of maintenance activities through providing maintainers with the information they need in order to repair and maintain assets quickly and effectively
- When major capital maintenance activities are planned, such as demolition, upgrade or refurbishment of an asset, good and up to date asset data (maintained as part of BIM compliant processes) will reduce risk and uncertainty during the bidding process and result in a smoother start to design activities with fewer ‘surprises’. It should also significantly reduce the need for asset surveys since you should know about the current asset configurations, so surveys should be to confirm information is correct and therefore not need for full asset surveys to be carried out.
These latter two benefits are reliant on the models and information delivered as part of a BIM compliant project being maintained throughout the life of an asset. These approaches are defined in PAS 1192-3 and also support effective asset management, as defined in ISO 55000.
It would be an opportunity lost if good quality BIM models used for asset construction were not kept up to date by maintenance staff who may either not provide asset updates, or may provide them on local record drawings only.
So, if you are implementing BIM (or considering doing so) make sure that you consider how to BIM enable your whole organisation, and not just the capital projects team.
