Feature
BIM there, done th BIM and FM
By Simon Lewis, Partner, and Vicky McCombe, Managing Associate at law firm Womble Bond Dickinson
In our recent review of the second edition of the CIC BIM protocol (Second Helpings) we noted references to an Asset Information Model (AIM) which had been introduced into the second edition and suggested that the implications of using the protocol for the Facilities Management (FM) phase of a project needed to be worked through. In this article we consider how BIM will operate during the FM phase and the practical issues that this raises. Given that the application of BIM to existing assets is bound to be more extensive and consequently involve
greater
resource than the application of BIM to new build alone, it is important to understand the structure of the underlying PAS 1192-3 and the practical issues that arise. PAS 1192-

3 is concerned with the availability, integrity and transfer of data and information during the operational phase of an asset’s life. It introduces the AIM which is, as the CIC protocol points out, a maintained Information Model which is intended to govern the use, maintenance and operation the asset. The obvious difference between the AIM and the Information Model which operates in the new build phase (which used to be referred to as the Project Information Model (PIM)) is that the AIM will have to cater for a more flexible sequence of activities through the asset life cycle, dealing with a mixture of planned and unplanned events that could happen in any order between the points of asset handover and asset disposal. These planned and unplanned events are
referred to in PAS 1192-3 as “triggers”. A trigger is a planned or unplanned event that changes an asset or its status by way of a trigger-related event, which is a response to a trigger, reflected in the altered state of the asset in the AIM. Either an AIM will already be in existence when a trigger occurs or a new AIM can be created in response to a trigger and at the inception of a trigger- related event. Triggers would therefore
include planned and unplanned maintenance works, refurbishment and update, variations and end of life works such as demolition, decommissioning and mothballing. The AIM should be put in place at the
beginning of the FM phase of the asset’s life cycle or when that asset is acquired by its new owner if there is not already an AIM
