Background Information / Main Objective
The solution was to “bring” the existing CBS to the office making it accessible to the team in their computers.
3D Scanner Technology is based in the ultra-quick survey of millions of points. The result is a point-cloud of the reality around the instrument. This point-cloud is similar to a panoramic 3D picture where every pixel has coordinates.
3D Scanner Technology is not an innovation at Heathrow, it has been used for different purposes like surveys and as-build records. The FAUK team decided to give it a different uses for the replacement of the Inflatable Roof of the CBS:
Base document for the Dilapidation Survey of the existing building before starting the works.
360 panoramic views of the interior of the building in order to:
o Understand the building and its constraints
o Take accurate measures (each pixel has coordinates) without the need to actually going into the facility.
A laser scan of the existing building was made before the works started on site and another one after the completion of the works. These two point-clouds helped us compare the “before2 and “after” of the works.
The 360 panoramic views were accessible to the team in their computers via a free web based software that runs on Internet Explorer. The software used was TruView from Leica Geosystem.
Homepage: a 3D view/map of the building with symbols (yellow triangle) which indicate where each survey/panoramic view has been taken
Clicking in one of the symbols, will take you to the specific view
Once in the view, different tools are available like measures, checking coordinates and annotations
From one of the views, you can move to the next ones
It looks like a Google Street view of the interior of the building where you can wander around.
