Demolition in Sydney comes with strict safety and licensing requirements, especially for high-risk projects or those involving asbestos. From residential teardowns to large-scale commercial demolitions across landmarks like the Sydney Opera House and Barangaroo, experience truly matters.

This guide covers everything you need to know from verifying licenses and safety protocols to understanding timelines and council approvals so you can select a demolition partner who ensures your project starts on a solid foundation.

What Makes Demolition Work High-Risk

Demolition work ranks among the most dangerous construction activities, requiring specialized skills, training, and proper licensing. Building demolition and excavation are inherently high-risk operations with potential for catastrophic incidents if not handled properly.

Structural hazards and collapse risks

The unpredictability of structural integrity makes demolition particularly hazardous. Buildings can unexpectedly collapse due to weakened materials, undetected damage, or improper sequencing during the demolition process. 

Consequently, what appears stable might suddenly fail. Induced collapse, a method involving systematic removal of key structural members to cause controlled collapse, presents significant dangers. 

This technique has resulted in uncontrolled collapses of residential buildings, leading to worker injuries and damage to nearby properties. Furthermore, workers sometimes re-enter demolition footprints after unsuccessful collapse attempts, placing themselves at extreme risk.

Use of heavy machinery and explosives

Heavy machinery essential for demolition presents substantial dangers. Excavators, bulldozers, and cranes can create deadly situations through improper operation or poor visibility, with workers getting struck, pinned, or crushed. Additionally, demolition machinery requires skilled operators who understand load capacities and tipping risks. 

For projects requiring explosives, specialized expertise is mandatory. Explosives must only be handled by licensed competent persons with specific experience in demolition applications. 

Moreover, detailed blast management plans must be developed and authorized before any explosive demolition can begin, with comprehensive contingency planning for all possible scenarios.

Presence of asbestos and hazardous materials

Older buildings often contain dangerous substances that become hazardous during demolition. Asbestos, prohibited since December 2003, still exists in older structures within fibrous cement sheeting, external cladding, flue pipes, drains, and roofing materials. 

Disturbing these materials releases tiny fibers that cause serious diseases like asbestosis, lung cancer, and mesothelioma, conditions that typically manifest 20-30 years after exposure. Other hazardous materials commonly encountered include lead, polychlorinated biphenyls (PCBs), contaminated dust, and combustible materials. 

Professional demolition companies in Sydney must follow strict protocols for identifying and safely removing these substances before demolition begins.

Legal and Licensing Essentials in Sydney

In Sydney’s construction industry, understanding demolition licensing requirements is essential for legal compliance and ensuring safety on work sites. The regulatory framework has evolved to better manage the inherent risks associated with demolition activities.

When a demolition license is required

Licensing requirements in Sydney depend primarily on the height and complexity of the structure. Any demolition of structures that are at least 6 meters high requires proper licensing. 

For structures less than 6 meters that don’t involve special conditions, no license is necessary. However, even for smaller projects, demolition work involving asbestos or hazardous materials typically requires an unrestricted demolition license.

Class 1 vs. Class 2 demolition explained

In NSW, these are formally known as Unrestricted (DE1) and Restricted (DE2) demolition licenses. An Unrestricted Demolition License is required for structures exceeding 15 meters, 

chemical installations, projects involving tower cranes, mobile cranes over 100 tons, pre-tensioned components, floor propping, or explosives. Conversely, a Restricted Demolition License covers structures between 6-15 meters or projects using load-shifting machinery on suspended floors.

Role of nominated supervisors and mutual recognition

Every licensed demolition company Sydney must have at least one named supervisor who physically oversees all demolition work. These supervisors must have completed 10 specific units from Certificate III and IV in Demolition. 

Notably, interstate license holders can work in NSW through Automatic Mutual Recognition, although they must notify SafeWork NSW beforehand. This arrangement applies across Australia except Queensland.

Notification and compliance with WHS regulations

Demolition contractors must notify SafeWork NSW at least 5 calendar days before commencing any demolition involving structures over 6 meters, load-shifting machinery on suspended floors, or explosives.

 Failure to comply can result in immediate fines. From March 2023, demolition licenses are valid for five years rather than two. Additionally, by March 2025, all demolition workers must complete the SafeWork NSW-approved training course CPCCDE3016.

How to Choose a Safe and Reliable Demolition Contractor

Selecting a qualified demolition contractor requires thorough vetting to ensure your project proceeds safely and legally. The selection process might seem overwhelming, but following these essential steps will help you make an informed decision.

Verify licensing and insurance

Firstly, confirm that any demolition company Sydney has appropriate licensing from NSW Fair Trading. For structures containing hazardous materials, contractors need an unrestricted demolition license. 

Equally important, verify their license online through the Service NSW website. Beyond licensing, ensure the contractor maintains adequate insurance coverage, including:

• Public liability insurance (protecting against third-party claims)
• Workers compensation insurance
• Contract works insurance

Specialized demolition insurance is essential because standard business policies typically don’t cover demolition-specific risks.

Ask about safety protocols and SWMS

A reputable demolition contractor must prepare a Safe Work Method Statement (SWMS) for all high-risk construction work. This document outlines potential hazards, risk assessment procedures, and control measures implemented to ensure safety. Request to see their safety management systems and ask about their Lost Time Injury rate.

Evaluate their asbestos handling capabilities

Prior to demolition, contractors must check for asbestos. For removal of more than 10m² of non-friable asbestos or any friable asbestos, they need specialized licenses (Class B or Class A respectively). Verify they employ proper decontamination procedures and air monitoring when required.

Check for local experience in Sydney suburbs

Experienced contractors familiar with Sydney’s local regulations can navigate permits and approvals efficiently. Companies with extensive experience across Sydney suburbs understand area-specific requirements and challenges. 

Consider contractors who have operated throughout various regions including Eastern Suburbs, Inner West, Northern Beaches, and Western Suburbs.

Planning for a Smooth Demolition Project

Managing your demolition project effectively requires meticulous planning from start to finish. A successful outcome depends on understanding realistic timelines while anticipating potential challenges.

Timeline and project milestones

The complete demolition process typically takes several weeks, not just the few days of physical demolition. For standard residential demolitions in Sydney, the on-site work typically requires 1-3 days, while the entire process, including approvals, preparation, and cleanup, spans 4-8 weeks.

Initially, obtaining council approvals like Complying Development Certificates (CDCs) takes 2-6 weeks. Afterwards, service disconnections, asbestos removal (taking 1-2 days if required), and site preparation must occur before machinery arrives.

Communication with neighbors and council

Throughout the project, maintaining open lines of communication prevents conflicts. In metropolitan areas, certifiers must inform neighbors within a 20-meter radius at least 14 days before CDC approval. Subsequently,  you must notify these neighbors again at least seven days before construction begins in metropolitan areas, or two days in rural and regional areas. 

This written notification is mandatory, not optional. Considerate contractors provide details about work schedules, potential noise periods, and contact information for addressing concerns.

Post-demolition site preparation

Once demolition concludes, site preparation becomes crucial. This phase includes clearing remaining debris, grading the land for proper drainage, soil testing, and utility planning. The site must be properly prepared for future construction to prevent structural issues later.

Common delays and how to avoid them

Permit complications, asbestos discoveries, and service disconnection issues frequently cause setbacks. Additionally, weather disruptions can significantly impact outdoor demolition work. To minimize delays, secure permits early, conduct thorough pre-demolition assessments, maintain dedicated crews, and document project progress regularly.

Conclusion

Choosing the right demolition company in Sydney starts with putting safety first.
