This KN Group subgrade inspection checklist supports roadworks and civil construction teams in assessing subgrade readiness and quality. It guides inspectors to record overnight rainfall and site conditions, capture photos, confirm correct water truck levels, and verify compaction with 100% SMDD density targets. The checklist includes proof rolling, string tests, identification of areas of concern with photos, and documentation of inspection results. Sign-off fields for KN and contractor or council representatives help ensure compliance and traceability.
