Before mobilisation, print the eNOC and the approved work description. Cross-check the company’s COC class against the active permit line items, not the generic business licence.
If the work package split between trades (MEP, wet fire, special hazards), each trade must be represented by an approved technician in that class.
Use the ADCD eServices to verify a technician COC in real time the morning of the inspection; expired same-day is a common no-entry cause.
