Facilities management / As-built models

An as-built model – with information captured during the design and construction phases of the project – can be a valuable resource during the operational phase of the project, if data is in an appropriate format. Define the facility management requirements to determine what information to gather.

Typical uses include:

  • Space management and tracking
    – space utilisation, allocation of space to building occupants.
  • Asset management
    – allocation and tracking of furniture, fittings and equipment.
  • Maintenance scheduling.
  • Building system performance analysis.

As a minimum, facility management information should be provided in a digital form and organised and indexed in a clear, logical manner that allows the information to be easily retrieved by anyone with basic computer skills using readily accessible software.

GBXML/commissioning

General

Green Building Mark-up Language (GBXML) is a methodology to electronically transfer building information on completion of construction for facilities management purposes. Spreadsheets for some systems are available for download. Third-party utilities facilitate the automatic creation and transfer of some data between BIM and XML spreadsheets via Industry Foundation Class (IFC) files as an intermediate stage, and some BIM software may include creation of, and data transfer to, the spreadsheet directly without making use of intermediate IFC files. Where possible, use automatic means to create and fill in the XML spreadsheets.

Other FM information handover/commissioning systems

General

Where the client and BIM Team determine that use of the GBXML system is not appropriate for the project, they define the specific information required for facility management purposes and the strategy for delivering it.

Requirements

As a minimum, the development process for the proposed system addresses the following issues:

  • Identify facility management information required by end users.
  • Organise and index information to facilitate its retrieval by required search criteria.
  • Incorporate file formats.
  • Software applications required to access and/or manage the information.
  • System features and functionalities required, eg. ability to update information, create reports in the desired format, ability to integrate with the building’s systems, eg. Building Management Systems (BMS.)
  • Strategy for collecting the required information throughout the project and delivering it to the client at a defined time.

Security assessment and disaster planning

An as-built model can be used to evaluate the physical security and survivability of a facility. An as-built model can also be a useful emergency response planning tool if provided to emergency services. The model – coupled with the Building Management System – can be used to identify the nature and location of the problem in the building and the best route to it.

The project team should liaise with local emergency service providers to establish their information requirements and agree emergency protocols.

Record specific uses of BIM for these purposes in the Project BIM Brief.
