ComplianceA shored or sloped excavation method used to protect workers from cave-ins during underground pipeline or utility work. Subcontractors are typically required to design and document the system before crews enter any trench deeper than 1.2 metres. Compliance with provincial safety codes is mandatory and directly affects site access approvals.
