In Singapore, demolition work is a vital phase in both residential and commercial renovation or redevelopment projects. Whether it’s tearing down non-structural walls in a flat or completely demolishing a landed property, demolition is more than just brute force — it involves planning, permits, safety protocols, and professional execution.
This guide covers the essentials of demolition work in Singapore, including the regulatory guidelines, cost factors, and step-by-step processes to help homeowners, developers, and business owners understand what to expect.
What Is Demolition Work?
Demolition work refers to the systematic dismantling, breaking down, or removal of buildings, structures, or interior elements. It can range from small-scale hacking (like tile or partition removal) to large-scale total demolition of entire buildings.
The main types of demolition work include:
- Interior demolition: Removal of non-structural elements like walls, ceilings, flooring, tiles, and built-in furniture.
- Partial demolition: Taking down specific parts of a structure, such as staircases, extensions, or walls.
- Total demolition: Complete teardown of a building or house, often for redevelopment purposes.
Each of these requires different skill sets, tools, and legal considerations.
Regulations and Approval Requirements
Demolition work in Singapore is subject to strict regulations to ensure structural safety, public health, and minimal disruption to surrounding areas.
1. Building and Construction Authority (BCA)
For complete building demolitions, the BCA requires a permit submission and approval. The demolition must be planned and overseen by a Professional Engineer (PE), who will assess the building’s structure and recommend safe demolition methods.
2. Urban Redevelopment Authority (URA)
For redevelopment projects, URA approval may be required before any demolition can begin, especially if the new structure will differ in zoning or land use.
3. Housing & Development Board (HDB)
In HDB flats, hacking or demolishing walls — even non-load-bearing ones — requires a renovation permit and must be carried out by HDB-registered contractors. Structural walls cannot be altered.
4. Management Corporations (MCSTs)
For condominiums and commercial buildings, the MCST may impose additional requirements, including renovation deposits, restricted working hours, and noise control.
Typical Demolition Process
Step 1: Site Assessment
A professional contractor will inspect the space and identify:
- Structural components
- Utilities (electrical, plumbing, gas)
- Asbestos or hazardous materials
- Waste disposal and access routes
Step 2: Permit Application
The necessary documents — including floor plans, PE endorsements (if needed), and approval letters — are submitted to the relevant authorities for approval.
Step 3: Utility Disconnection
Utilities such as water, gas, and electricity are disconnected to prevent accidents during the demolition.
Step 4: Demolition Execution
Using tools like electric jackhammers, wall chasers, and hydraulic breakers, the demolition is carried out in phases. Protective coverings are used to prevent damage to adjacent areas.
Step 5: Waste Disposal
Debris is sorted, loaded into bins or trucks, and transported to licensed disposal facilities. Recycling is done wherever possible.
Step 6: Post-Demolition Cleaning
The area is cleaned and prepared for the next phase of renovation or construction.
Cost of Demolition Work in Singapore
Demolition costs vary widely depending on:
- Size and type of property
- Scope of work (partial vs. full)
- Waste volume and disposal method
- Required permits and professional endorsements
- Accessibility and location
Here is a rough estimate for common types of demolition work:
| Demolition Type | Estimated Cost Range (SGD) |
|---|---|
| Hacking of partition walls | $400 – $800 per wall |
| Tile and flooring removal | $3 – $7 per square foot |
| Full interior strip-out (3-room HDB) | $4,000 – $6,000 |
| Landed house full demolition | $20,000 – $40,000+ |
| Office reinstatement demolition | $5 – $12 per square foot |
Always ask for itemized quotations and ensure the contractor includes disposal and site clearance in the pricing.
Safety Measures and Risk Management
Demolition work presents numerous risks, from falling debris to structural collapses. Professional contractors in Singapore follow stringent safety protocols such as:
- Erecting barriers and warning signage
- Using PPE (Personal Protective Equipment)
- Conducting structural assessments
- Dust control via water spraying or barriers
- Noise management during permitted hours
For large-scale demolitions, a method statement and risk assessment report are required and must be reviewed by a Professional Engineer.
Tools and Equipment Used
Depending on the scale and complexity, contractors use a range of tools:
- Electric jackhammers – for concrete breaking
- Demolition saws – for controlled cutting
- Wall chasers and grinders – for piping and electrical line removal
- Hydraulic crushers and breakers – for large concrete structures
- Scaffolding and ladders – for safe access
Proper equipment ensures that the work is efficient, safe, and causes minimal disruption to neighboring units.
Environmental and Noise Considerations
Demolition can create significant dust, noise, and debris. Singapore enforces laws that limit these impacts:
- NEA (National Environment Agency) sets noise limits for residential areas.
- Debris must be disposed of at licensed collection centers.
- Air and water pollution must be minimized through dust suppression methods.
Contractors must manage these aspects carefully to avoid penalties or complaints.
Choosing the Right Demolition Contractor
When selecting a demolition contractor, ensure they:
- Are licensed and experienced
- Can manage permit applications
- Provide transparent, itemized quotes
- Include insurance coverage
- Have a strong safety track record
If you’re working within an HDB flat, always confirm that the contractor is HDB-registered and familiar with the necessary guidelines.
Conclusion
Demolition work in Singapore is a regulated, multi-step process that demands expertise, compliance, and detailed planning. Whether you’re preparing a flat for renovation or clearing a building for redevelopment, engaging a skilled demolition team ensures the job is done legally, safely, and efficiently.
By understanding the costs, processes, and requirements involved, homeowners and property managers can better plan their projects and avoid costly mistakes. Always prioritize safety, proper approvals, and experienced professionals for any demolition task — big or small.
