Geotechnical QA/QC for Infrastructure Projects: Building Reliable Foundations Through High-Quality Subsurface Data
Every successful infrastructure project begins below the surface. Before a highway is widened, a bridge is constructed, a railway is extended, or a water treatment plant is built, engineers must understand the subsurface conditions that will support the structure for decades to come. This understanding comes from geotechnical investigations. Boreholes, Standard Penetration Tests (SPT), cone…

SPT and N-Value QA/QC Procedures: Improving the Accuracy and Reliability of Standard Penetration Test Data
The Standard Penetration Test (SPT) is one of the most widely performed in-situ geotechnical tests in the world. From building foundations and bridges to highways, dams, pipelines, and environmental investigations, SPT results are used daily by geotechnical engineers to evaluate subsurface conditions and support critical engineering decisions. At the heart of every SPT is the…

Geological Data Quality and Resource Estimation: Why High-Quality Borehole Data Is the Foundation of Reliable Resource Models
Whether evaluating a mineral deposit, planning a mine, designing a major infrastructure project, or assessing groundwater resources, every geological interpretation begins with data. Drillholes, samples, laboratory analyses, geological logging, geotechnical measurements, and geophysical surveys collectively form the foundation upon which three-dimensional geological models and resource estimates are built. The accuracy of these models depends directly…

Recovery, RQD, SCR, and TCR Validation: Ensuring Reliable Core Logging Data for Better Engineering Decisions
Core drilling provides some of the most valuable information used in geotechnical engineering, mining, hydrogeology, and environmental investigations. However, the value of that information depends entirely on the quality and consistency of the recorded data. Among the most important measurements collected during core logging are Core Recovery, Rock Quality Designation (RQD), Solid Core Recovery (SCR),…

Core Logging QA/QC in Mineral Exploration
Best Practices for Producing Accurate, Consistent, and Defensible Geological Core Data Diamond drilling is one of the largest investments made during a mineral exploration program. Every metre of core recovered represents significant drilling costs and provides valuable geological information that may influence exploration strategy, resource estimation, mine planning, and investment decisions. Because of this, the…

Borehole Data Governance for Transportation Projects
Ensuring Trusted, Secure, and Reusable Geotechnical Data Throughout the Infrastructure Lifecycle Modern transportation infrastructure projects generate an extraordinary volume of geotechnical information. Highway expansions, bridge replacements, rail corridors, airports, tunnels, ports, and rapid transit systems all depend on accurate borehole investigations to characterize subsurface conditions before construction begins. Over the lifetime of a transportation asset,…

Geotechnical QA/QC for Infrastructure Projects
Best Practices for Delivering Reliable Subsurface Data for Roads, Bridges, Dams, Tunnels, Railways, and Major Civil Engineering Projects Every major infrastructure project begins below the surface. Before the first foundation is poured, bridge pier constructed, tunnel excavated, or highway embankment built, engineers must understand the ground conditions on which the entire project will depend. That…

SPT and N-Value QA/QC Procedures
Best Practices for Ensuring Accurate Standard Penetration Test Data in Geotechnical Investigations The Standard Penetration Test (SPT) remains one of the most widely performed in-situ tests in geotechnical engineering. For more than a century, engineers have relied on SPT N-values to estimate soil density, relative strength, bearing capacity, liquefaction potential, settlement characteristics, and numerous other…

Geological Data Quality and Resource Estimation
Why High-Quality Geological Data Is the Foundation of Reliable Mineral Resource Models Every mineral resource estimate begins with geological data. Drill holes, core logs, assays, geotechnical measurements, structural observations, density determinations, and survey information collectively define the size, shape, grade, and confidence of a mineral deposit. Sophisticated geological modelling software and advanced geostatistical techniques can…

Recovery, RQD, SCR, and TCR Validation
Best Practices for Validating Rock Core Quality Measurements in Geological and Geotechnical Investigations Rock core logging is one of the most important activities performed during geotechnical investigations and mineral exploration drilling. The measurements collected from drill core—including Core Recovery, Rock Quality Designation (RQD), Solid Core Recovery (SCR), and Total Core Recovery (TCR)—provide essential information about…
