Temporary working platforms are essential for the safe operation of cranes, piling rigs, and heavy plant, yet they often receive limited engineering attention. Cook Costello analysed 41 Plate Load Tests across seven New Zealand sites to develop locally relevant acceptance criteria, confirming that stiffness and strength must be verified independently to achieve safer, evidence-based platform design.

Step‑by‑step guide showing how to estimate soil density, shear modulus (G₀) and effective pressure from seismic CPT data to develop site‑specific correlations for accurate seismic site response.

The article explains why accurate soil classification, strength and compaction testing improve foundation design, reduce risk and support sustainable, cost‑effective construction.
