BIM guidance to optimise the operational phase: defining information requirements based on ISO 19650

“…To implement BIM effectively in an organisation, BIM goals need to be defined by the client early in the process (Helmus et al , 2018). To ensure transparency, the goals must be cascaded to all appointed parties from the lead appointed party downwards.…”

“…To achieve the objectives, it is helpful to think about “BIM use cases,” which focus on specific processes (both for construction and in operation), and the intended benefits BIM can deliver. From an operational perspective to be successful requires delivery and operational teams review specific operational processes to help clearly define how the use cases can help achieve specific operational, tactical and strategic goals (Helmus et al , 2018). Figure 1 illustrates the main steps that have to be completed in a BIM project.…”

“…They need to be specific to projects, although elements can be generic. They also need to be clear and succinct to ensure clarity and to avoid any misunderstandings from any parties that the right information is provided in the right format, at the right time and in and adequate level of detail (Helmus et al , 2018).…”

“…The ISO standards also clearly state information requirements must be defined by the client as the “appointing party” at the start of the process and represent a solid basis for starting a construction project with BIM (Ashworth et al , 2019). The resulting OIR, PIR and AIR help to allow the clear definition of the EIR which should also be defined by the appointing party and form part of the tender contract (Helmus et al , 2018). The delivery team, as “the appointed party,” then has to respond to the requirements in the EIR clearly describing how they will meet the requirements.…”

“…Another significant potential of BIM according to Helmus et al (2018) is to support design solutions that deliver sustainable and economical outcomes by providing models and information for typical simulations, e.g. energy analyses.…”
