Demolition Building Certifiers

Demolition projects require building certification before work can commence, regardless of the size of the structure being demolished. The demolition permit or approval ensures that the demolition work will be carried out safely, that hazardous materials (particularly asbestos) are properly managed, and that neighbouring properties and infrastructure are protected during the demolition process. Building certifiers assess the demolition work plan against building regulations and work health and safety requirements before issuing the necessary approvals.

The demolition certification process begins with a detailed demolition work plan prepared by a licensed demolition contractor. This plan addresses the sequence of demolition, the methods to be used, the management of hazardous materials, traffic management during the demolition, protection of neighbouring buildings and services, and arrangements for waste disposal and recycling. The building certifier assesses this plan and, if satisfactory, issues the demolition permit. The certifier may also inspect the demolition work at key stages to verify compliance with the approved plan.

Asbestos management is the most critical safety consideration in demolition certification. Buildings constructed before 1990 commonly contain asbestos in fibro sheeting, insulation, floor tiles, roof materials, and other components. An asbestos survey by a licensed assessor is required before demolition can proceed, and any asbestos-containing materials must be removed by a licensed asbestos removal contractor before general demolition begins. The certifier verifies that appropriate asbestos management procedures are in place, including air monitoring, clearance certificates, and lawful disposal records.

For partial demolitions (where part of a structure is removed while the remainder is retained), the certifier must be satisfied that the retained structure will remain stable during and after the demolition. This typically requires a structural engineer's assessment of the impact of the demolition on the remaining building. The certifier reviews this assessment and ensures that any temporary support structures or shoring required during the demolition are adequately designed and installed.

Demolition certification costs typically range from $500 to $3,000 depending on the size of the structure, the presence of hazardous materials, and the complexity of the demolition (particularly for partial demolitions or demolitions near sensitive infrastructure). These costs are separate from the demolition contractor's fees, asbestos removal costs, and waste disposal charges. Early engagement with a building certifier ensures that all regulatory requirements are identified and addressed before the demolition contractor mobilises, avoiding delays and additional costs on site.
