A question to geotechnical practitioners. Please share your thoughts and experience. Are you satisfied with your long term monitoring strategy? Is it effective or is it just ‘ticking a box’? Is this something we need to be concerned about? Are we too reactive, focused on the short-term operational response? Please share an example or case study, either publicly or privately with me, that you’re aware of where back analysis showed, after the fact, that long term monitoring tools (Eg InSAR, prisms, GNSS) detected a significant but very small change in behaviour in a slope or a dam or similar where, had anyone been watching, perhaps something could have been done to prevent disaster? I can name at least 4-5 examples just off the top of my head. Is it good enough to say we measured it if no one saw it in time to act?

Check out this week's blog! We've recently conducted a few buried obstruction surveys, and thought we'd share the journey. #buriedobstructionsurvey #utilitysurvey

Tech Used: Ground Penetrating Radar Project Type: Facility Pavement Assessment Location: Rockhampton, QLD   SureScan was engaged to perform an extensive ground-penetrating radar (GPR) survey on a processing facility as part of an expansion project.   The primary objective of the project was to undertake GPR survey on select areas to identify structural characteristics such as reinforcement detail and concrete thicknesses.   The GPR was deployed to ensure shallow subsurface detection, with scan paths laid out in a grid pattern to ensure full coverage of the areas of interest.   Looking for accurate structural insights? Find out how we can help you > www.surescan.com.au #SureScan #ConcreteScanning #NonDestructiveTesting #DefectIdentification #Rectification

Surveying His Domain

Surface roughness is a key parameter in terrain analysis, offering insights into natural processes and geophysical features. Our survey highlights areas of high roughness, depicted in purple on the map, indicating increased landslide risk due to unsettled terrain. #SurfaceRoughness #TerrainAnalysis #LandslideRisk #infrastructure #construction

Surveyors, what strategies and technologies do you find most effective in minimizing errors and ensuring high precision when conducting geodetic surveys in challenging terrains?

🏔 Proud to have originated a kinematic analysis using DIPS to process field discontinuity data, informing slope remediation projects. By meticulously studying rock formations and structural characteristics, we identified potential instability factors and devised targeted solutions. Each measurement translated into actionable insights, guiding our efforts to enhance safety and resilience in challenging terrain around Scotland. Reflecting on the satisfaction of blending field expertise with cutting-edge analysis for impactful outcomes. #Rocksloperemediation #fielddataanalysis #Geotechnicalengineering #dips #mapping

The development of instability conditions (such as rockfall) on surfaces suitable for scan line surveying, and the inability to conduct vertical scan line surveys despite horizontal scan line surveys being feasible along surfaces with high slopes, restricts our ability to obtain data about the discontinuities of the rock mass. The method developed by Prof. Adrián Riquelme solved all these problems. When we compare the results with the field data, it is really excellent. I believe that DSE (Discontinuity Set Extractor) will be our greatest assistant in mapping the discontinuities in the rock mass.
