What Is PFI Drone Inspection?
PFI drone inspection applies unmanned aircraft systems to conduct BCA-mandated periodic facade inspections. PFI — periodic facade inspection — is a regulatory requirement under the Building Control Act ensuring building facades remain safe throughout their service life.
Traditional PFI methods rely on rope access, BMUs, or scaffolding to bring inspectors close to the facade. These are expensive, time-consuming, and create worker safety risks. Drone-based PFI eliminates these challenges by capturing equivalent or superior data from remotely operated aircraft.
Our PFI drone inspections use enterprise-grade platforms with 48-megapixel cameras delivering 5mm/pixel resolution and radiometric thermal sensors detecting temperature differentials as small as 0.05 degrees Celsius.
PFI Requirements Under BCA
| Requirement | Detail |
|---|---|
| Building age trigger | 20 years from TOP date |
| Frequency | Every 5 years after first PFI |
| Responsible party | Building owner or MCST |
| Report submission | Within deadline to BCA |
| PE endorsement | Report must be endorsed by registered PE |
| Remedial works | Defects must be rectified within stipulated timeframe |
How PFI Drone Inspection Works
Permit Application
We review building specs, assess airspace, and submit CAAS activity permits. Flight plans developed based on facade geometry.
Systematic Drone Survey
CAAS-licensed pilots capture high-resolution RGB and thermal imagery across all elevations. Every square metre photographed with controlled overlap.
Defect Classification
Engineers analyse imagery identifying cracks, spalling, delamination, sealant failure, corrosion. Each defect classified by type and severity per TR 78.
BCA-Ready Report
Completed PFI report with annotated photographs, elevation maps, severity assessments, and remediation recommendations. PE-ready format.
Advantages of Drone PFI
- 30-50% Cost Savings — no scaffolding or rope access mobilisation costs.
- 70% Faster — 20-storey building inspected in 1-2 days instead of 1-2 weeks.
- Zero Worker Risk — all operators at ground level. No MOM safety concerns.
- Consistent Quality — every section at same resolution and angle. No inspector fatigue variability.
- Thermal Imaging Included — detect moisture, delamination, and insulation defects invisible to visual inspection.
- Digital Archive — every image timestamped and georeferenced for cross-cycle comparison.
PFI Drone Inspection Pricing
| Building Size | Drone PFI | Traditional PFI |
|---|---|---|
| Low-rise (up to 10 storeys) | $1,500 - $3,000 | $4,000 - $8,000 |
| Mid-rise (10-20 storeys) | $3,000 - $6,000 | $8,000 - $18,000 |
| High-rise (20-40 storeys) | $5,000 - $10,000 | $15,000 - $35,000 |
| Super high-rise (40+) | $8,000 - $15,000 | $25,000 - $50,000+ |
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.
