Common Mistakes

Common errors to avoid in your coursework

Misinterpreting test standards leading to incorrect test setup or procedure.
Inadequate site preparation, such as not clearing loose material, affecting test accuracy.
Incorrect use of conversion factors or charts when calculating results.
Failing to account for environmental conditions that influence test outcomes.
Neglecting to verify equipment calibration before testing.
Poor recording practices, such as missing units or illegible entries.
**Misconception:** Geotechnical work is simply about digging holes and collecting dirt. **Correction:** While excavation and sampling are part of it, geotechnical activities are a highly technical and scientific discipline. They involve precise, standardised testing procedures, detailed observation, accurate data collection, and skilled interpretation of results to inform critical engineering decisions, requiring a deep understanding of soil mechanics and material science.
**Misconception:** Laboratory test results are inherently 100% accurate and don't need verification. **Correction:** Laboratory results can be influenced by various factors, including sample disturbance during collection, incorrect preparation, equipment calibration errors, and human procedural mistakes. Robust quality control measures, regular equipment calibration, adherence to standards, and cross-referencing with field observations are crucial to ensure the reliability and validity of results.
**Misconception:** All types of soil and rock can be tested using the same methods. **Correction:** Different soil and rock types possess unique engineering properties (e.g., cohesion, friction angle, plasticity, permeability). Consequently, specific tests are designed to characterise these distinct properties. For instance, a Standard Penetration Test (SPT) is more relevant for granular soils, while undrained shear strength tests are critical for cohesive clays. Using inappropriate test methods will yield irrelevant or misleading data.
