Our expertise

When planning a project in Shellharbour, it’s essential to choose the right method for your needs. The available options depend on factors such as project size, site conditions, and local regulations. Here are the key options:

Residential Projects

If you’re removing an old home or structure to make way for a new build, residential demolition is the best option. This process can include fully or partially demolishing a house, and safe asbestos removal if required.

Commercial and Industrial Projects

For larger structures such as warehouses, office buildings, and industrial sites, commercial projects requires specialised equipment and strict compliance with safety and environmental laws.

Excavation and Site Preparation

Excavation services include land clearing, trenching, and earthmoving to prepare a site for construction. Whether it’s digging foundations, levelling land, or creating drainage systems, proper excavation ensures stability for future developments.

Selective and Interior Demolition

Not all projects require tearing down an entire structure. Selective demolition allows for the removal of specific sections while preserving the integrity of the remaining building. This is ideal for renovations, extensions, or upgrades.

Controlled and Mechanical Demolition

For precise and safe removal of structures, this technique uses heavy machinery such as excavators, bulldozers, and wrecking balls.

Controlled demolition involves carefully planned techniques, often using advanced equipment to minimise impact on surrounding areas.

Environmental and Sustainable Demolition

For eco-conscious projects, sustainable methods focus on recycling materials, reducing landfill waste, and minimising environmental impact.

Frequently Asked Questions About Demolition And Excavation in Shellharbour

Before starting the project in Shellharbour, you may need approval from the local council and other regulatory bodies. The permits required depend on factors such as the project size, location, and environmental impact.

Development Approval (DA): In most cases, a Development Application (DA) is required from Shellharbour City Council before the project can begin. This ensures that the project meets zoning, heritage, and environmental regulations.

Some minor works may be exempt, but it’s best to check with the council.

Construction Certificate (CC): Once the DA is approved, a Construction Certificate (CC) may be needed. This confirms that the work complies with building regulations and approved plans before construction or site preparation begins.

Asbestos Removal Permit: If the structure contains asbestos, specific permits and procedures must be followed for safe removal. Licensed professionals must handle asbestos removal under SafeWork NSW guidelines.

Work, Health & Safety (WHS) Requirements: For larger projects, compliance with SafeWork NSW safety regulations is crucial. Depending on the scope, a Demolition Work Plan and Excavation Management Plan may be required.

Road or Footpath Occupation Permit: If the project affects public spaces, such as footpaths or roads, a permit from the local council is necessary to ensure public safety and minimal disruption.

Selecting the right contractor in Shellharbour is crucial for ensuring safety, efficiency, and compliance with regulations. Here are the key factors to consider when making your decision:

Check Licensing and Certifications: A reputable contractor should be fully licensed and insured to perform this kind of work in New South Wales. Ensure they hold the necessary qualifications, including a SafeWork NSW demolition licence and relevant excavation permits.

Experience and Expertise Matter: Look for a contractor with proven experience in handling projects similar to yours. Whether it’s residential, commercial, or industrial projects, an experienced team will have the skills to manage challenges like asbestos removal, underground utilities, and site preparation.

Compliance with Safety and Environmental Standards: Safety is a top priority. A professional contractor should follow Work Health and Safety (WHS) regulations, use proper protective equipment, and implement dust and noise control measures.

Transparent Quotes and Contracts: A trustworthy contractor will provide a detailed quote outlining the scope of work, timeline, and costs. Be wary of vague pricing or contractors who cannot provide a written agreement—transparency is key to avoiding unexpected expenses.

Reputation and Customer Reviews: Research the contractor’s reputation by checking online reviews, testimonials, and previous project portfolios. Recommendations from local clients can help gauge their reliability and quality of work.

Equipment and Technology: Modern methods require advanced machinery and techniques for precision and efficiency. Ensure the contractor has well-maintained equipment suited for your project’s scale and complexity.

Communication and Customer Service: A reputable contractor will provide clear communication, keep you updated throughout the project, and be responsive to any concerns. Good customer service reflects professionalism and commitment to client satisfaction.

The timeline in Shellharbour depends on factors like project size, site conditions, permit approvals, and weather conditions.

However, here’s a general guide to help you understand how long your project might take.

Residential Poject Timeline

  • Small structures (sheds, garages, fences): 1–3 days
  • Single-storey home demolition: 5–10 days
  • Double-storey home demolition: 7–14 days
  • Partial demolition (e.g., removing a wall or extension): 3–7 days
  • Asbestos removal (if needed): Can add 2–5 days depending on the amount

Commercial and Industrial Project Timeline

  • Small commercial buildings: 1–3 weeks
  • Large industrial sites: 4–8 weeks (varies based on structure size, hazardous materials, and complexity)

  • Trenching for utilities (e.g., plumbing, electrical): 1–3 days
  • Rock excavation (if required): Can extend the project by 1–2 weeks

Factors That Can Affect the Timeline

  • Permit approvals – Council approvals can take a few weeks to a few months, so planning ahead is crucial.
  • Site conditions – Rocky terrain, tree roots, or underground utilities may slow down the project.
  • Weather – Heavy rain can delay the project and make the site unsafe for machinery.
  • Waste disposal and recycling – Sustainable methods (sorting and recycling materials) may take extra time.

Every project is different, and at DemoEx, we provide realistic timelines based on your specific needs. Our experienced team ensures an efficient and safe project, minimising delays and keeping your project on track.
