Delivery Strategy for Asset Information
What Does This Mean?
This is where the client defines the requirements of the asset information model (AIM), the model that is delivered at the completion of the capital delivery phase. It includes information such as the format of the model, the information contained within the model and how the data should be transferred into an existing or proposed CAFM system.
Asset Information Model
The asset information model is the model delivered from the delivery team to the client at the completion of construction of an asset (also referred to as the completion of the capital delivery phase).
The level of definition (LOD) for the model at delivery will define how much detail is contained within the model, this could advance as far as an as-built model (LOD 5), which is verified by a point cloud survey. The detail of the LOD required should be clearly scheduled out in the Model Production & Delivery Table (MPDT).
The file format of the AIM should be selected to ensure integration with any existing systems. If a proprietary file format (such as Autodesk Revit RVT) is selected due to existing systems, then it may also be sensible to also request an open file format such as IFC. This will maximise the likelihood of continued support for the file format throughout the life of an asset.
Clarification of the information contained within the model can quickly become very detailed and often requires reference to a separate document, the Asset Information Requirements (AIR).
Developing a comprehensive AIR will have multiple benefits by ensuring the consistency of delivered information. An AIR is a strategic level document on a level with a strategic OIR (Organisational Information Requirement).
The selection of the asset information that is contained and delivered within the AIM should, at first, be informed by a client’s asset management requirements. For example if a client has a current and effective CAFM system, then a good starting point would be to select the assets that are currently managed. Of course this will often be expanded to improve the existing system.
So to ensure that asset information is delivered within the AIM, each type of asset required should be listed out. The type of asset should be referenced against a standard classification, for example Uniclass and then each required data field for each asset should be listed, including any external items of data such as product data sheets or photographs.
COBie UK (as detailed within BS 1192-4) is a good place to start to understand the standard data fields available for exporting asset information from an AIM.
