What is ‘building information modelling according to the ISO 19650 series’? ‘Building information modelling (BIM) according to the ISO 19650 series’ is about getting benefit through better specification and delivery of just the right amount of information concerning the design, construction, operation and maintenance of buildings and infrastructure, using appropriate technologies. This helps deliver the efficiencies and savings envisaged by the UK Government and others. The ISO 19650 series applies throughout the whole life cycle of an asset and it applies to all types of asset in the built environment – buildings, infrastructure and the systems and components within them. A successful outcome from adopting the processes in ‘BIM according to the ISO 19650 series” would have the following features: Clear definitions for the information needed by the project client or asset owner, and for the standards, methods, processes, deadlines and protocols that will govern its production and review. The quantity and quality of information produced being just sufficient to satisfy the defined information needs, whilst not compromising health and safety or security. Too much information represents wasted effort by the supply chain and too little means clients/owners take uninformed decisions about their projects/assets. Efficient and effective transfer of information between those involved in each part of the life cycle – particularly within projects and between project delivery and asset operation. Informed and timely decision making. The ultimate result would be the efficiencies gained through reduction of waste/rework in the design, construction, operation and maintenance activities plus the reduction of risk.
