During the last decade Building Information Modelling (BIM) has emerged as a key enabler within the construction industry to increase productivity. While the benefits have been mostly realised within the Design/Construction phase, the adoption of BIM within the operational phase has been significantly limited. One of the critical challenges to utilising BIM within the operational phase is for asset own-ers/maintainer to develop information requirements that support the BIM process. UK BIM standard PAS 1192-3 provides information requirements frame that states that an organisation should develop Organisational Information Requirements (OIR) that then aid in generating individual Asset Information Requirements (AIR). While it is critical that the OIR generate the AIR, it can be witnessed that this is too much of a leap for most organisations. This paper proposes a practical Top-Down methodology that aids in bridging this “gap” by utilising an organisational point of view of assets as the functional output they support and proposes the development of Functional Information Requirements (FIR) to bridge this gap.
