Introduction
L&M Survey Services offer a range of different services to the railway sector and hold a framework agreement with Carillion Civil Engineering to provide railway services for Network Rail infrastructure in Scotland. We have invested in Network Rail approved utility tracing equipment and all our surveyors carry valid PTS certificates. Our railway projects have included topographical surveys, engineering surveys, 3D laser scanning tunnel surveys, monitoring works (structure, track and embankment), permanent way surveys, precise levelling, and platform and structure gaging surveys.
Case Study
Construction company Edmund Nuttalls contracted L&M to undertake survey work on the new Airdrie to Bathgate railway line. Initially we installed a robust control network across the site for use by engineers. Then up to 4 teams of engineers worked on site providing engineering survey services, including setting out of embankments, earthwork calculations, drainage setting out and as-built surveys of the new track.
Specialist Equipment
Leica TPS1200+
For our topographical, engineering and quarry surveys, we use the TPS1200+ total station which provides the best reflectorless EDM performance available in the world – a reflectorless range of 2000m, PinPoint accuracy of 2mm and laser dot size of 2cm/50m. It is more efficient and faster than any other one-person-total station and therefore more cost effective. Working with an improved Automatic Target Recognition (ATR) sensor, the TPS1200+ tracks and follows the prism with the highest degree of accuracy and reliability.
Leica ScanStation
We were the first company in Europe to use the Leica ScanStation for measured building surveys. This fastest pulsed laser scanner has survey-grade tilt compensation which means lower project costs, greater field flexibility and higher project accuracy. With a capture range of up to 300m for 90% surface reflectivity, ScanStation delivers survey accuracy for each measurement and its ultra-fine scanning and small laser spot allow for optimal project control and registration.
