Monitoring Surveys
Laser surveys have ongoing long term monitoring projects, in particular in the coastal marine environment but also on the new motorway network.

We are currently scanning an eroding beach cliff face and carrying out volume survey of beach nourishment on a yearly interval. This is a long term project (over 30 years) which requires durable and stable control stations.

Another long term monitoring project involves precisely measuring pavement levels and over-bridge levels on a number of motorway schemes. A precision digital level and precise invar staff is necessary to achieve the consistency and accuracy between successive measurements.

Laser surveys have developed precision leveling routines which can be employed where conventional leveling is not possible such as in areas of restricted access (cannot hold a staff). Precision autolock total stations are used with a mini prism to achieve repeatable levels to an accuracy of +/- 0.2mm.
