3D Laser Scanning for Asbuilt BIM Models
Transcript of 3D Laser Scanning for Asbuilt BIM Models
parametric rules for each object. For instance, a door of certain material and dimension is parametrically related and hosted by a wall. 3D LASER SCANNING ASBUILT BIM MODELS What is 3D Laser Scanning Also known as LiDAR (Light Detection & Ranging)
Camera like instrument which uses a laser beam to measure distance
Fires laser and for each point the laser hits it records an xyz value.
As well as recording distance it records the reflectivity of a surface which gives an intensity value.
Some scanners have in builts camera which takes photos,
These are used to add colour (RGB) values. How does it work ? Fast data collection What do you get? POINT CLOUDS Advantages VERY FAST DATA COLLECTION
• ACCURATE +/- 4MM
• VISUAL 3D RESULTS
• SAFE ACCESS HIGH/RESTRICTED AREAS
• LOTS OF DELIVERABLES
• NOTHING MISSED Multiple Setups Deliverables Pointcloud Asset Management Deliverables Webshare / TruView Deliverables Intelligent 3D Models Deliverables Point clouds

As part of ongoing investment in their Birmingham Plant they required a laser survey and asbuilt model. The survey was required to be carried out in a very small timeframe to avoid disruption to the plant.
Once the survey was completed a 3D asbuilt model was created to allow the engineers to virtually carry out design work and simulation of the installation of 2 new furnaces. Animation Made up of two storeys and covering over 10,000 sq m, the UWE conference centre is a vast building. Formerly the Hewlett Packard offices, the building has recently been acquired by the University of Bristol. Parsons Brinckerhoff the consultant engineers carrying out the refit of the building were looking for methods to survey the very complex ceiling void.
Located 4m above ground level and packed with piping and ducts conventional survey methods would have been impossible. Company Background Formed in 1988 Range of Topographic, Measured Building Survey & Dimensional Control services for Infrastructure

BUILDING INFORMATION MODELLING BIM COBIE In June 2011 the UK government published its Building Information Modelling (BIM) Working Party Strategy.
This report announced the Government’s intention to require collaborative 3D BIM (with all project and asset information, documentation and data being electronic) on its projects by 2016. The software and data requirements for this detailed in the report are Construction Operations Building Information Exchange (COBie). MONUMENT MALL Asbuilt BIM for Refurb
