Demolition Services in Singapore

Definition: Demolition services involve the systematic tearing down or dismantling of structures, buildings, or specific parts of a property. In Singapore, demolition is a highly regulated process that requires careful planning, adherence to safety standards, and compliance with government regulations.

Types of Demolition Services 

1. Interior Demolition:

   • Description: Focused on dismantling the interior components of a building without affecting the external structure. This type of demolition includes the removal of internal walls, ceilings, flooring, fixtures, and fittings.
   • Applications: Renovating homes, offices, and commercial spaces to modernize layouts, change room configurations, or install new designs.
   • Example: A homeowner might remove internal walls to create an open-plan living space.

2. Selective Demolition:

   • Description: Targeted demolition of specific sections of a building, such as removing a single floor, wall, or structure while preserving the rest of the building.
   • Applications: Useful for upgrading or altering parts of a property without compromising the integrity of the entire structure.
   • Example: A business may choose to demolish and rebuild only the front facade of a shop while keeping the rear section intact.

3. Structural Demolition:

   • Description: The removal of entire structures, including both interior and exterior components. This type of demolition is typically used to clear a site for new construction.
   • Applications: Residential or commercial buildings that need to be demolished to make way for new projects.
   • Example: A developer may demolish an old apartment block to build new condominiums.

4. Complete Building Demolition:

   • Description: Involves the complete teardown of buildings, either manually or with the help of heavy machinery such as excavators and bulldozers.
   • Applications: Required when buildings are no longer safe, are obsolete, or need to be removed for redevelopment purposes.
   • Example: Demolishing a large industrial facility to clear land for a new factory.

5. Mechanical Demolition:

   • Description: Involves the use of heavy machinery and equipment like wrecking balls, bulldozers, and hydraulic excavators to tear down large-scale structures quickly and efficiently.
   • Applications: Suitable for demolishing high-rise buildings, commercial complexes, and industrial structures.
   • Example: Using a crane with a wrecking ball to bring down a multi-story car park.

6. Explosive Demolition:

   • Description: Also known as implosion, this type of demolition uses controlled explosives to bring down a building in a precise, calculated manner. It requires extensive planning and coordination to ensure safety.
   • Applications: Used for demolishing large, tall, or complex structures in highly congested urban areas.
   • Example: Imploding a high-rise office building in the CBD (Central Business District) for new construction.

The Demolition Process

1. Initial Consultation:

   • Description: The demolition contractor meets with the client to assess the project, determine the scope of work, and evaluate the condition of the property. This is followed by providing recommendations and a cost estimate.

2. Site Survey and Inspection:

   • Description: A thorough survey of the building or structure to identify potential hazards such as asbestos, lead, or hazardous materials, and determine the structural integrity of the building. This includes a review of nearby structures that could be affected.

3. Planning and Permits:

   • Description: A detailed demolition plan is created, including methods of dismantling, safety protocols, and environmental considerations. Contractors are required to apply for permits from relevant government agencies, such as the Building and Construction Authority (BCA) and the National Environment Agency (NEA).
   • Importance: Ensuring that the project complies with Singapore’s strict construction and safety regulations, including noise control and waste disposal.

4. Preparation of Site:

   • Description: The area around the structure is secured, and utilities such as water, electricity, and gas are disconnected. Surrounding buildings and pedestrian areas may be temporarily fenced off to ensure safety.
   • Hazard Mitigation: Steps are taken to remove hazardous materials like asbestos before demolition begins.

5. Demolition Execution:

   • Description: The actual dismantling or destruction of the building using the appropriate method (manual, mechanical, or explosive). This phase requires expert handling of machinery and adherence to safety measures.
   • Dust and Noise Control: Equipment such as dust suppression systems and noise barriers are used to minimize environmental impact.

6. Debris Removal and Site Cleanup:

   • Description: After demolition, all debris and materials are cleared from the site. Waste is disposed of according to NEA regulations, and recyclable materials are sorted for reuse.
   • Importance: Ensures the site is clean and ready for further construction or landscaping work.

7. Final Inspection:

   • Description: The site is inspected by both the contractor and local authorities to ensure the demolition was completed safely and in accordance with the project’s specifications.
