Newport Quarry - Granite Quarry Volume Measurement & Monitoring

Challenge

Accurately measuring material volumes at an active granite quarry presented significant challenges. The site included steep, irregular quarry faces and complex terrain that made traditional surveying methods difficult, time-consuming, and potentially unsafe.

In addition, quarry operations required reliable volume calculations to track material removal over time—without disrupting ongoing extraction activities or placing survey crews in hazardous locations.

Solution

LandTech utilized 3D laser scanning to document existing quarry conditions and generate precise, repeatable volume measurements. Using terrestrial laser scanning, the team captured detailed point-cloud data of quarry faces and stockpiles, collecting up to one million data points per second to accurately model complex, non-flat terrain.

Scan data was tied into established coordinate systems using GPS-integrated control points, ensuring consistency and accuracy across surveys. Individual scans were combined into a single three-dimensional surface model, allowing LandTech to calculate material volumes with a high degree of precision. The site was rescanned at defined intervals to track ongoing material removal over time.

Results

  • Delivered accurate volume calculations for complex quarry excavation areas
  • Enabled safe data collection from a distance without interrupting active quarry operations
  • Provided repeatable, survey-grade measurements to track material removal over time
  • Improved efficiency compared to traditional surveying methods in steep, inaccessible environments

LandTech’s laser scanning approach provided quarry operators with a reliable, efficient method for monitoring excavation volumes while maintaining safety and operational continuity.
