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.

The Benefits Of Precise Levelling Surveying

Precise levelling surveying is a critical technique in the field of geodesy and civil engineering, offering numerous benefits that make it indispensable for various projects.

This method is renowned for its exceptional accuracy in measuring the elevation differences between points on the Earth’s surface, ensuring high precision in determining gradients, alignments, and the geometry of an area. It is instrumental in the construction and design of infrastructure such as roads, bridges, and buildings, where precise elevation data are crucial for stability and drainage planning,

Precise levelling plays a vital role in monitoring land subsidence, aiding in flood risk management, and contributing to large-scale topographic mapping. By providing detailed and reliable elevation data, precise levelling surveying enables engineers and surveyors to make informed decisions, enhancing the efficiency and safety of construction projects and environmental management.

Precise Levelling Surveying FAQs

Precise levelling is a surveying technique used to determine the exact elevation differences between points on the Earth’s surface. It involves high-accuracy measurements to establish benchmarks for construction, engineering, and mapping projects.

Precise levelling is crucial for:

  • Infrastructure Development: Ensuring accurate elevation data for the construction and design of roads, bridges, and buildings, which is vital for stability and drainage planning.
  • Subsidence Monitoring: Detecting and quantifying land subsidence, which is essential for assessing ground stability in areas affected by mining or natural resource extraction.

Environmental Management: Aiding in flood risk management and large-scale topographic mapping by providing detailed elevation data.

Projects that often require precise levelling include:

  • Mining Subsidence Monitoring: Assessing ground movement in former coal mining areas to detect potential subsidence.
  • Landfill Settlement Quantification: Measuring settlement in landfill sites to ensure environmental safety and compliance.

Brinefield Solution Mining Monitoring: Providing early warning systems for potential problems in brine extraction areas, which are some of surveying’s longest-running monitoring programmes.
