Precise Levelling Surveying
Large area subsidence monitoring schemes are based on a combination of precise levelling methods and network adjustment calculations.
Being located in a former coal mining area, Survey Operations personnel have naturally gained extensive experience of large area monitoring schemes relating to mining subsidence.
Over the years, these skills have also been applied to quantifying landfill settlement and as part of early warning systems for potential brinefield solution mining problems.
Nationally, brinefield schemes represent some of surveying’s longest running monitoring programmes and some have been operating for well over 50 years.
This work involves precise levelling over hundreds of acres of open countryside in and around the brine extraction areas to identify possible cavity deformation or other subterranean problems.
Increasingly, once fully developed, the underground brine cavities are being used for gas storage thereby ensuring that precise levelling skills will be needed long into the future.
