Hanger Lane Gyratory Underpass
Project: Hanger Lane Gyratory Underpass
Client: TFL
Survey Date: August 2012
Survey Brief
J.C.White Geomatics Ltd. were commissioned to provide 3D laser scan data and an accurate 3D model of the underpass to ascertain height restrictions and for proposed refurbishment of the lighting.
Survey Methodology
The survey was carried out over two nightime possessions which included fully controlling the scans and referencing the information to O.S. grid and datum.
The 3D model was constructed entirely from the pointcloud data and QA checks indicated a sub 5mm fit throughout. A 2D drawing was also extracted from the 3D model for traditional plan production.
Rendered lighting applied to model.

'I would like to say that JC White Geomatics are relatively local to us and we have come across their work over the years which has always been of a very high standard. I have interviewed a couple of their staff for membership into the ICES and have found them a credit to the profession. The company seems to have a very contented workforce with the management investing heavily into training.'
