How to Choose a Demolition Contractor in NSW: The Complete Checklist

Selecting a demolition contractor in NSW is not the same as selecting a general builder or tradesperson. Demolition carries specific regulatory requirements, licensing obligations, and liability exposures that make the selection process critically important for any project manager or principal contractor.

This checklist covers what you must verify before engaging any demolition contractor in New South Wales.

1. SafeWork NSW Demolition Licence

All demolition work in NSW must be conducted under the supervision of a SafeWork NSW-licensed demolition supervisor. There are two licence classes: Demolition Work (DW) for structures under 6 metres, and Demolition Work with High Risk (DWHR) for structures over 6 metres and complex demolitions.

Ask for licence number and verify on the SafeWork NSW licence register before signing any contract. An unlicensed contractor exposes you to personal liability under the WHS Act.

2. Hazardous Materials Assessment

Any structure built before 1990 is likely to contain asbestos. Any structure built before 1970 may contain lead paint. Any structure in an industrial or commercial use may contain PCBs, contaminated soils, or other hazardous materials.

A compliant demolition contractor will conduct (or engage a specialist to conduct) a hazardous materials assessment before mobilising. This assessment must identify, classify, and provide a management plan for any hazardous materials on site.

3. EPA Waste Credentials

Demolition waste is regulated under the NSW Protection of the Environment Operations Act. All waste transport and disposal must be carried out by EPA-licensed contractors, and waste must go to licensed facilities.

Ask for the contractor's EPA waste transport licence number and confirmation of which licensed facility they use for disposal.

4. Insurance — What You Must Check

• Public liability — minimum $20 million for most commercial demolition work
• Professional indemnity — if they're providing design or engineering input
• Workers compensation — must be current for all workers on your site
• Plant and equipment insurance — for any plant they bring to site

5. WHS Documentation

A professional demolition contractor will provide a complete WHS documentation package before starting work. This must include SWMS (Safe Work Method Statements) for all high-risk work activities, a hazardous materials management plan, a waste management plan, and a site-specific induction record.

6. References and Track Record

Demolition is a small industry. Ask for two or three recent references from project managers at similar projects. A contractor that can't provide references has something to hide.
