Understanding BCA's 5-Year Requirement
Singapore's Building Control Act requires all building owners to conduct periodic facade inspections for public safety. The facade inspection — the 5-year building inspection — applies to every building reaching 20 years from its TOP date.
This regulation exists because facades deteriorate in Singapore's tropical climate. UV exposure with index above 10, humidity exceeding 80%, heavy monsoon rainfall, and thermal cycling from air conditioning accelerate degradation. Tiles loosen, concrete spalls, sealants fail, and fixings corrode — creating falling object hazards.
The BCA 5-year inspection is not optional. Owners and MCSTs that fail to comply face enforcement action. Drone technology provides a faster, safer, and more cost-effective compliance method.
BCA 5-Year Inspection Process
BCA Notification
BCA notifies building owners or MCSTs when their building approaches the deadline. Early planning is essential.
Appoint Inspection Team
Engage a qualified team — CAAS-licensed drone operator and registered PE. We provide both through our PE partner network.
Conduct Facade Inspection
The inspection covers all external elements: walls, windows, cladding, projections. Our drones capture comprehensive visual and thermal data.
Report and Submission
PE reviews data, endorses the report, and submits to BCA. Defects requiring remediation are categorised by urgency.
What the Inspection Covers
External Wall Finishes
Tiles, render, paint, plaster, and cladding checked for cracking, delamination, bulging, and detachment.
Windows and Glazing
Frames, seals, and glass inspected for corrosion, sealant failure, and structural integrity. Thermal imaging detects seal failures.
Projections and Attachments
Sun shades, ledges, balcony rails, signage brackets — highest falling object risk when fixings corrode.
Structural Elements
Concrete beams, columns, and slabs checked for spalling, cracking, exposed reinforcement, and water staining.
Cost Comparison — Drone vs Traditional
| Height | Drone | Rope Access | Scaffolding |
|---|---|---|---|
| 5-10 storeys | $1,500-$3,000 | $4,000-$8,000 | $10,000-$20,000 |
| 10-20 storeys | $3,000-$6,000 | $8,000-$18,000 | $20,000-$40,000 |
| 20-40 storeys | $5,000-$10,000 | $15,000-$35,000 | $35,000-$60,000 |
| 40+ storeys | $8,000-$15,000 | $25,000-$50,000+ | $50,000+ |
For MCSTs managing sinking fund budgets, drone inspection significantly reduces BCA compliance cost burden across multiple cycles.

Frequently Asked Questions
Singapore Context — Why This Matters
Singapore's built environment presents unique challenges for building inspection. With over 14,000 buildings subject to periodic facade inspection requirements, the scale of compliance activity is significant. The tropical climate — UV index consistently above 10, humidity averaging 80 percent, heavy monsoon rainfall, and constant thermal cycling from air conditioning — accelerates facade deterioration faster than in temperate climates.
The combination of ageing building stock and aggressive environmental conditions means facade defects develop faster and can progress to safety-critical levels more quickly than building owners expect. Tiles that might last 30 years in a temperate European climate may begin delaminating within 15-20 years in Singapore. Sealants rated for 20-year service life may fail in 10-12 years under constant UV bombardment.
This is why Singapore's regulatory framework mandates periodic inspections and why the quality of those inspections matters. A thorough drone inspection that identifies early-stage delamination allows preventive maintenance at a fraction of the cost of emergency repairs after tiles have fallen. Thermal imaging that detects moisture infiltration behind cladding prevents the progressive structural damage that unchecked water ingress causes over years.
For building owners and MCSTs, investing in quality inspection data from CAAS-licensed drone operators is not just about regulatory compliance — it is about protecting asset value, ensuring occupant safety, and managing long-term maintenance costs effectively. The buildings that are well-maintained and well-documented command higher market values and lower insurance premiums than those with incomplete inspection histories.
