What Is Facade Inspection in Singapore?
Facade inspection is the systematic examination of a building's external surfaces to identify defects, deterioration, and safety hazards. In Singapore, facade inspection is governed by the Periodic Facade Inspection (PFI) regime under the Building Control Act. This mandatory programme requires building owners to have their facades professionally assessed at regular intervals to prevent falling debris incidents that endanger public safety.
Singapore's tropical climate creates uniquely harsh conditions for building facades. Constant high humidity, intense ultraviolet radiation, frequent heavy rainfall, and daily thermal cycling accelerate the degradation of concrete, tiles, cladding, sealants, and coatings. These environmental stresses cause spalling, debonding, cracking, and corrosion that can lead to facade elements detaching and falling from height — a serious public safety risk in a densely built city.
The PFI regime was introduced following several incidents of falling facade debris in Singapore. Under the current regulations, buildings that are more than 13 metres tall and have obtained their Temporary Occupation Permit (TOP) more than 13 years ago must undergo facade inspection every 7 years. Building owners who fail to comply face fines of up to $10,000 and potential prosecution under the Building Control Act.
A qualified facade inspection company in Singapore provides the data capture, analysis, and reporting that competent persons need to fulfil their BCA obligations. At SG Drone Inspections, we use advanced drone technology to deliver faster, safer, and more comprehensive facade assessments than traditional inspection methods.
Which Buildings Need Facade Inspection?
Not every building in Singapore requires periodic facade inspection. BCA has established clear criteria that determine which buildings fall under the PFI regime.
Height Requirement
Buildings must be more than 13 metres tall (approximately 5 storeys or more) to require periodic facade inspection. This threshold captures mid-rise and high-rise buildings where falling facade elements pose the greatest risk to pedestrians.
Age Requirement
Buildings must have obtained their Temporary Occupation Permit (TOP) more than 13 years ago. This recognises that facade deterioration is cumulative and that newer buildings have not yet reached the stage where systematic defects typically develop.
Inspection Cycle
Once a building qualifies, facade inspection must be conducted every 7 years. BCA issues facade inspection orders to building owners, specifying the deadline for completing the inspection and submitting the PFI report.
Building Types
The PFI regime covers all building types that meet the height and age criteria — residential condominiums, HDB blocks, commercial offices, retail malls, industrial buildings, hotels, hospitals, and mixed-use developments.
How Drone-Based Facade Inspection Works
Modern facade inspection in Singapore increasingly relies on drone technology for data capture. BCA's TR 78 technical reference establishes the framework for using unmanned aircraft systems (drones) to conduct visual facade inspections, setting standards for camera specifications, flight parameters, image quality, and reporting.
Our drone-based facade inspection methodology follows TR 78 precisely. A drone equipped with a 48-megapixel camera and optional thermal sensor systematically scans every elevation of the building facade. Pre-programmed flight paths ensure 80% frontal and 60% side overlap between images, guaranteeing complete coverage with no blind spots.
The key advantages of drone-based facade inspection over traditional rope access include:
- Speed — A 20-storey building that takes rope access teams 2-3 weeks to inspect can be surveyed by drone in 2-3 hours, capturing thousands of geo-tagged images covering every square metre of facade.
- Safety — Zero fall risk. No workers suspended at height. No scaffolding erection hazards. The drone operates from a safe ground position while the pilot maintains visual line of sight.
- Cost — Drone facade inspection costs 30-50% less than equivalent rope access inspections by eliminating the labour-intensive setup, equipment hire, and extended site occupation.
- Coverage — 100% facade coverage versus the partial inspection typical of rope access, where inspectors can only examine what is directly in front of them on each descent.
- Thermal detection — Optional thermal imaging detects hidden defects — subsurface delamination, moisture ingress, and tile debonding — that are invisible to the naked eye during visual-only inspections.
After data capture, our team processes the imagery to create a complete facade mosaic. Every defect is identified, annotated, classified by type and severity, and mapped to a facade grid reference. The competent person (PE or RA) uses this data to produce their professional assessment and BCA submission report.
BCA Requirements for Facade Inspection
Understanding BCA's facade inspection requirements helps building owners prepare for their PFI obligations and avoid penalties. Here are the key regulatory requirements that every building owner and MCST should know.
Competent Person Requirement
Every periodic facade inspection must be supervised by a competent person — either a Professional Engineer (PE) or Registered Architect (RA) who is registered with BCA for facade inspection work. The competent person is responsible for the professional assessment, defect classification, and final PFI report submitted to BCA. Building owners must appoint their own competent person; our team works directly with your PE or RA to deliver the data they need.
Defect Classification System
BCA uses a three-category defect classification system for facade inspection findings:
| Category | Severity | Action Required |
|---|---|---|
| Category 1 | Minor — cosmetic defects, hairline cracks, minor staining | Monitor and maintain. No immediate repair required, but should be addressed during next maintenance cycle. |
| Category 2 | Moderate — cracks wider than 0.3mm, partial delamination, sealant failure | Repair within specified timeframe set by the competent person. Typically 6-12 months. |
| Category 3 | Critical — imminent risk of falling debris, severe spalling, detached elements | Immediate rectification required. Protective canopies must be installed. Emergency repairs within days. |
PFI Report Submission
The competent person must submit the completed facade inspection report to BCA by the deadline specified in the facade inspection order. The report includes a summary of facade condition, inventory of all identified defects with classification, photographic evidence, recommended remedial works, and a timeline for repairs. Late or incomplete submissions may result in further enforcement action by BCA.
Facade Inspection Cost in Singapore
Facade inspection pricing in Singapore varies based on building size, height, number of elevations, facade complexity, and access requirements. Here is a transparent pricing guide based on drone-based facade inspection.
| Building Type | Height | Price Range |
|---|---|---|
| Low-Rise Residential (HDB, condo) | 5-10 storeys | $3,000 — $5,000 |
| Mid-Rise Commercial / Residential | 10-20 storeys | $5,000 — $10,000 |
| High-Rise Tower | 20-40 storeys | $8,000 — $15,000 |
| Add-on: Thermal Imaging | Any height | +$1,500 — $3,000 |
What is included: CAAS permit application, drone data capture for all elevations, image processing and defect annotation, facade condition mapping, and comprehensive inspection report ready for competent person review. Competent person (PE/RA) fees are separate — building owners engage them independently.
Factors that affect facade inspection cost:
- Number of elevations — A building with 4 exposed facades costs more than one with 2 accessible sides. Corner buildings and freestanding towers require more flight time.
- Facade complexity — Buildings with setbacks, cantilevers, curtain walls, or multiple cladding types require additional flight paths and longer analysis time.
- Access restrictions — Buildings in controlled airspace (near Changi, Paya Lebar, Seletar) require additional CAAS coordination that may affect scheduling and cost.
- Thermal imaging — Adding infrared thermal scanning increases cost but detects hidden defects that visual inspection alone cannot identify.
