What is an As-Built Model?

‘As-built documentation is developed after construction (or a particular phase of construction), either immediately or at any time following. As-Built drawings and models are developed by physically measuring the existing facility for the purpose of developing CAD or BIM documentation.’

An As-Built Model allows us to see how the object, in this case, the building, is functioning in real-time, as well as how it will function in a range of real and hypothetical scenarios. An As-Built Model also allows us to have a map of each and every asset that exists within the building from pipes, air conditioning vents and plumbing through to electrical appliances, furniture, and windows.


What goes into creating an As-Built Model?

Data, data, and more data… An As-Built Model begins with static data such as floor plans, pipe layouts as well as heating and ventilation systems before real-time data such as temperature and humidity can be added.


How do I obtain and measure real-time data in my model?

An As-Built Model uses data collected from various different sensors to tell you how the assets within the building are functioning. For example, if there was a leak, you would be able to easily identify where the leak was coming from and arrange for repair or replacement without even having to be on-site. The data collected by these sensors can be mapped into the As-Built Model and you can then use this data to understand how the building, as well as the various assets within it, are functioning in real-time in the real world.


How do As-Built Models help Facilities and Estates Management teams?

  • Having an As-Built Model allows us to operate troubleshooting systems from remote locations.
  • This model can be used to perform a range of tests using different variables that could affect the function or performance of a particular asset as well as analysing how this could potentially affect the estate as a whole.
  • The digital model can also be used to examine any past issues that may have occurred and help to better prevent them from occurring again in the future.
  • Utilising an As-Built Model can also help to predict any future failures and enable you to schedule predictive maintenance in advance rather than panicking to fix faults as they occur.
