BIM (Building Information Modelling) is the future of construction. BIM gets people and information working together effectively and efficiently through defined processes and technology. In simple terms, BIM brings all the drawings, building information, equipment information (specifications, performance, warranty etc) and maintenance requirements in one model which can be viewed and managed during and after construction.
Computed Aided Design (CAD) packages such as revit and vector works have been developed to fully harness BIM functionality
However, so far since its introduction, BIM has not been fully accepted and despite the level 2 BIM (2016) government deadline, it's still just an idea to most construction people. The objective of the construction industry is to deliver projects on time, within budget and BIM helps to bring predictability to a project. BIM will also contribute to reducing cost and waste on a project.
In order for BIM to be implemented effectively and be a success, construction companies will need to invest in BIM competent personnel/contractors something which at the moment is not considered in the budgets hence why BIM has not been a success. Investment will also be required on the facilities management side in order to train the personnel who will be looking after the equipment as BIM is software based.
The idea of BIM is something exciting and with 3D printing, this also brings a lot of opportunities for the construction industry.
