Applying Building Information Modelling to Existing Buildings.

• This presentation is highlighting the benefits of using the latest Laser Scan Technology in

conjunction with Building Information Modelling.

• To understand the full advantages of applying Building Information Modelling to existing

buildings, this presentation will use the example of this auditorium.

• The Following is an example of the information that can be attained from a laser scan, and

what this data can be used to achieve.

What does a Laser Scan look like?

Building Information Modelling, Drawing is Dead – Long Live Modelling Keith Snook, RIBA Director of Research & Technical, http://www.cpic.org.uk/en/current-projects/bim/building-information-modelling.cfm

“Building Information Modelling is digital representation of physical and functional

characteristics of a facility creating a shared knowledge resource for information about it

forming a reliable basis for decisions during its life cycle, from earliest conception to

demolition.”

What is a laser Scanner?

• Devices which lead a Laser Beam are called Laser Scanners. There are Laser Scanner

heads which can be attached to Coordinate Measuring Machines (CMMs) for the

documentation of sites and buildings.A Coordinate Measuring Machine (CMM) captures

3D data from objects to give the position in XYZ, vectors etc. of the object.

• A Laser Scanner emits a Laser Beam and then measures the angle and distance of the

return laser beam by accurately measuring the time of the return Laser Beam.

• Laser Scanning means that surfaces or 3D forms are swept over in a horizontal or grid

pattern with a Laser Beam to measure or process these to generate a 3D picture. The

Scan Data can be saved to various file formats for manipulation and analysis.

Why use a Laser Scan in Building Information Modelling? • The Laser Scan Information can be accurate to within 0.01mm, and therefore can be used

to generate an accurate record of a building.

• The information from the scan can be used to generate a Building Information Model of

the existing building.

• Having an accurate Building Information Model at the commencement of a Project will

reduce risk of errors that would otherwise be caused by lack of information in a traditional

survey.

• Additional information that may be requested from the survey will already be in the scan,

and can be extracted to the Building Information Model, e.g. the position of sprinklers, pipe

and duct works, etc.
