JC White Geomatics has over 25 years experience of Railway surveys.

Laser Scanning London Bridge Railway Platform

Our first major railway project was the Channel Tunnel Terminal Site where we were responsible for all engineering surveys and setting out of track work on the site. We continue to work for Eurotunnel carrying out level monitoring of the tracks and monitoring other structures.

J C White Geomatics Ltd are very pleased to announce that the company has achieved Achilles RISQS Accreditation allowing us to work within the Railway Infrastructure.  We can therefore sponsor our own staff to obtain PTS Certification and have a number of PTS qualified surveyors.
