Guide to Hacking and Demolition Works for Office Spaces in Singapore

What's the Difference Between Hacking and Demolition?

"Hacking" in the Singapore construction context refers to breaking and removing built-in elements — partition walls, floor screeds, tile beds, and plaster finishes. The term is specific to Singapore and Malaysia and describes controlled, targeted removal work rather than wholesale structural clearance.

"Demolition" refers to removing larger structural or system components — suspended ceilings, raised access floors, full partition systems, and built-in joinery. In reinstatement, both terms are used together to describe the complete strip-out phase: everything installed during the tenancy that needs to come out before you hand back the keys.

Understanding the distinction matters because they attract different regulatory requirements, generate different volumes of waste, and require different on-site expertise. A contractor who conflates them may be underselling the complexity of the work.

Types of Hacking and Demolition in Office Reinstatement

1. Wall and partition removal — drywall, glass, demountable aluminium, or masonry partitions. Each material type has different waste and dust management requirements.
2. Ceiling removal — suspended ceiling grids and tiles, integrated light fittings, ceiling-mounted ACMV units, and any bespoke ceiling treatments. Above-ceiling conditions often reveal hidden surprises.
3. Flooring removal — raised access floors, carpet, vinyl, tiles, and screed down to the bare concrete slab. The concrete must be left clean and free of adhesive residue.
4. Built-in furniture and fixtures — custom joinery, reception counters, built-in cabinetry, server room infrastructure, and any other fixed installations.
5. MEP system disconnection — ACMV (air-conditioning), electrical distribution boards, sub-panels, conduits, plumbing modifications, and data and communications infrastructure.
6. Signage and branding removal — wall graphics, branded glass manifestations, cut vinyl lettering, external building signage, and directional wayfinding systems.

BCA and Regulatory Requirements in Singapore

All significant hacking and demolition works must comply with a set of overlapping regulations. Your contractor is responsible for knowing these — but you're responsible for confirming they do before work begins.

Do You Need a Permit?

Not all hacking work requires a formal permit from BCA. Non-structural partition removal and surface hacking — removing tile finishes, screed, or drywall — generally don't. The threshold is structural impact.

Work that may require a permit includes:

• Any hacking that affects the structural slab or load-bearing elements
• Modifications to fire protection systems (sprinklers, dampers, smoke detectors)
• Changes to the building's main electrical infrastructure
• Removal of structural columns, beams, or shear walls

Your contractor should conduct a site assessment and identify permit requirements before work starts — not after the hacking crew has already arrived. If they can't answer this question during the quote process, that's a problem.

Noise Restrictions

Singapore's Environmental Protection and Management Act (EPMA) restricts construction noise in commercial areas to Monday through Saturday, 7am to 10pm. Sundays and public holidays are restricted to non-noisy works only in most zones.

However, building management rules frequently impose tighter windows. Many Grade A and premium commercial buildings restrict hacking to before 8am or after 6pm — off-hours windows specifically to avoid disturbing other tenants. Some allow only overnight work for the most disruptive phases.

Best Practices

• Coordinate with building management before work starts — get written confirmation of access hours, contractor registration requirements, waste removal procedures, and any specific material restrictions
• Survey for hidden utilities before hacking — electrical conduits, data cabling, and plumbing buried in walls and floors must be identified and safely isolated before any breaking work begins. This is non-negotiable from a WSH perspective
• Use certified contractors familiar with WSH requirements — the site supervisor must hold a valid WSH certificate; confirm this before work starts
• Plan waste removal logistics before day one — construction waste cannot be accumulated in common areas or deposited in building bins. Have a licensed waste disposal contractor and approved facility confirmed in advance
• Document everything before, during, and after — photograph the space before work starts, photograph during (especially above-ceiling conditions), and photograph the completed strip-out. This is your protection if disputes arise at handover
• Protect adjacent areas — dust, vibration, and debris from hacking can affect neighbouring tenants. Hoarding, dust sheeting, and HEPA air filtration are standard practice in occupied buildings
