What Is Periodic Facade Inspection (PFI)?
Periodic facade inspection (PFI) is a mandatory building safety regime established under Section 28D of Singapore's Building Control Act. The regime requires building owners to engage a competent person to inspect the external facade of their building at regular intervals and report any defects to the Building and Construction Authority (BCA).
The PFI regime was introduced after several incidents of falling facade elements in Singapore caused injuries and, in some cases, fatalities. Concrete spalling, tile debonding, and cladding failures are accelerated by Singapore's tropical climate — high humidity, UV radiation, heavy rainfall, and thermal cycling cause progressive deterioration of building facades over time. Without systematic inspection, these defects go undetected until they become safety hazards.
PFI applies to buildings that meet two criteria: the building must be more than 13 metres tall (approximately 5 storeys), and the building must be at least 13 years old from its date of Temporary Occupation Permit (TOP). Once both criteria are met, the building enters the PFI cycle, and the owner must arrange for a facade inspection within a timeline specified by BCA. Subsequent inspections are required every 7 years.
The scope of PFI covers all external facade elements — concrete surfaces, render and plaster finishes, tiles and stone cladding, curtain wall systems, aluminium composite panels, precast elements, canopies, ledges, fins, and any other element attached to the exterior of the building that could potentially fall and cause harm.
BCA Requirements for Periodic Facade Inspection
BCA sets specific requirements that building owners must follow when arranging their periodic facade inspection. Understanding these requirements is essential to avoid penalties and ensure a smooth inspection process.
Building Height Threshold
PFI applies to buildings exceeding 13 metres in height, measured from the ground level to the highest point of the building. This threshold captures most buildings of 5 storeys and above, including HDB blocks, condominiums, commercial offices, and industrial buildings.
Building Age Trigger
The first PFI is triggered when a building reaches 13 years from its TOP date. BCA maintains records of all TOP dates and proactively issues notification letters to building owners approximately 6 months before their PFI is due. Owners should not wait for the letter — they should track their own TOP date and plan ahead.
7-Year Inspection Cycle
After the first PFI, subsequent inspections must be completed every 7 years. The 7-year clock starts from the date of BCA's acceptance of the previous PFI report. Building owners should diarise the next inspection date immediately upon completion of each cycle.
Competent Person (CP) Requirement
The facade inspection must be conducted or supervised by a Competent Person — either a Professional Engineer (PE) registered with the Professional Engineers Board, or a Registered Architect (RA) registered with the Board of Architects. The CP is personally responsible for the accuracy of the inspection and the PFI report.
The Competent Person must carry out a visual inspection of all accessible facade surfaces. Where direct visual inspection is not practical — for example, on high-rise facades without building maintenance units — the CP may employ alternative methods including drone-based inspection under the TR 78 framework, rope access teams, or scaffold-based inspection. The CP determines the appropriate method based on building characteristics and access constraints.
Upon completion of the inspection, the CP prepares and submits a PFI report to BCA. The report must document all identified defects, classify them by severity, include photographic evidence, and recommend remedial actions where necessary. BCA reviews the report and may require additional investigation or immediate remedial works for critical defects.
How Drones Support BCA Periodic Facade Inspection
Drone technology has fundamentally changed how periodic facade inspections are conducted in Singapore. BCA published TR 78 — a technical reference for visual inspection of building facades using unmanned aircraft systems — which establishes the framework for drone-based facade inspection as a compliant method for PFI.
Under TR 78, drones equipped with high-resolution cameras systematically capture imagery of the entire building facade. The drone follows pre-programmed flight paths at a controlled distance from the facade surface (typically 3-5 metres), ensuring consistent image quality and complete coverage. Images are captured with 80% frontal overlap and 60% side overlap, allowing the facade to be reconstructed as a continuous mosaic with no blind spots.
Advantages of Drone-Based PFI
- Complete facade coverage — drones capture 100% of the facade surface including areas that are difficult or impossible to reach by rope access, such as recessed panels, overhangs, and areas near rooftop equipment.
- Faster data capture — a 20-storey building that would take rope access teams 2-3 weeks can be surveyed by drone in 2-3 hours, significantly reducing project timelines and building disruption.
- Higher image quality — 48MP cameras capture defects as small as 0.5mm hairline cracks. Every image is geo-tagged with GPS coordinates for precise defect location mapping.
- Zero fall risk — no personnel are required to work at height during the data capture phase, eliminating the most dangerous aspect of traditional facade inspection.
- Thermal imaging capability — optional thermal cameras detect hidden defects such as moisture ingress, tile delamination, and insulation voids that are invisible to the naked eye.
- Cost savings of 30-50% — by eliminating scaffolding, gondola hire, and multi-week rope access teams, drone inspection is significantly more affordable than traditional methods.
Limitations to Be Aware Of
Drone inspection is a visual assessment method — it identifies surface-visible and thermal-detectable defects but cannot perform tactile tests such as hammer tapping or pull-off adhesion tests. Where the CP identifies areas of concern from drone imagery that require physical verification, targeted close-range inspection via rope access or BMU may still be needed for those specific locations. In practice, this means drone inspection covers the broad survey, and rope access is used only for the small percentage of areas flagged for further investigation — a hybrid approach that is both thorough and cost-effective.
Drone operations in Singapore also require CAAS (Civil Aviation Authority of Singapore) permits, which must be applied for and secured before the inspection date. Operations near airports, air bases, and controlled airspace require additional approvals. Our team handles all CAAS applications as part of the service.
PFI Timeline and Process
The periodic facade inspection process follows a structured timeline from BCA notification through to report submission and any required remedial works. Here is what building owners should expect at each stage.
BCA Notification
BCA issues a formal notification letter to the building owner approximately 6 months before the PFI deadline. The letter specifies the deadline by which the PFI report must be submitted. Building owners should begin engaging a Competent Person and inspection service provider upon receiving this notification — do not wait until the last month.
Appoint Competent Person
The building owner engages a Professional Engineer (PE) or Registered Architect (RA) as the Competent Person. The CP reviews the building's facade type, history, and any previous inspection records to plan the inspection methodology. If drone inspection is selected, the CP coordinates with the drone service provider on data requirements.
Facade Inspection
The inspection is conducted using the methodology determined by the CP. For drone-based inspection, our team captures high-resolution visual and thermal imagery of all facade elevations following TR 78 parameters. The drone data is processed, and a complete defect inventory is compiled with annotated imagery, severity classifications, and facade grid references.
PFI Report Preparation
The Competent Person reviews all inspection data, assesses each defect's severity and risk, and prepares the formal PFI report. The report includes facade condition assessment, defect inventory with photographic evidence, risk classification, and recommended remedial actions. Report preparation typically takes 2-4 weeks depending on building complexity and number of defects identified.
BCA Submission
The Competent Person submits the completed PFI report to BCA through the official submission portal. BCA reviews the report and may request clarifications or additional information. Once accepted, the PFI cycle is considered complete, and the 7-year clock resets for the next inspection.
Remedial Works (If Required)
If the PFI report identifies defects classified as critical or severe, BCA may issue a facade repair order requiring the building owner to carry out remedial works within a specified timeframe. The building owner must engage a contractor to rectify the defects and submit evidence of completion to BCA. For non-critical defects, remedial works should be planned and completed before the next PFI cycle.
Penalties for Non-Compliance
Building owners who fail to comply with BCA periodic facade inspection requirements face serious consequences. The Building Control Act provides for the following penalties.
| Offence | Penalty |
|---|---|
| Failure to carry out PFI within the required timeframe | Fine up to $5,000 |
| Failure to comply with facade repair order | Fine up to $10,000 and/or imprisonment |
| Continued non-compliance (ongoing offence) | Additional fine up to $250 per day |
| Facade element falls causing injury due to neglect | Criminal liability under the Act and potential civil claims |
Beyond financial penalties, non-compliance exposes building owners and Management Corporation Strata Title (MCST) council members to personal liability if a facade failure causes injury or property damage. Insurance coverage may also be voided if the building was not in compliance with statutory inspection requirements at the time of an incident. The cost of PFI compliance is far lower than the potential legal and financial exposure of non-compliance.
BCA Periodic Facade Inspection Cost Guide

Which Buildings Require PFI in Singapore?
The PFI regime applies broadly across building types. Common building categories subject to periodic facade inspection include:
- HDB blocks — managed by HDB Town Councils, which coordinate PFI across their estates. Individual flat owners are not individually responsible, but Town Councils must comply.
- Condominiums and private apartments — the MCST (Management Corporation Strata Title) is responsible for arranging PFI. The cost is typically funded from the sinking fund or management fund.
- Commercial office buildings — the building owner or managing agent arranges PFI. For strata-titled commercial buildings, the MCST is responsible.
- Industrial buildings and warehouses — owners of JTC, Mapletree, and other industrial buildings exceeding 13 metres must comply with PFI requirements.
- Hotels, retail malls, and mixed-use developments — the building owner or appointed property management company coordinates PFI.
- Institutional buildings — schools, hospitals, community centres, and government buildings are also subject to PFI when they meet the height and age criteria.
Buildings shorter than 13 metres, and buildings younger than 13 years from TOP, are exempt from PFI requirements. However, building owners of exempt buildings are still encouraged to conduct voluntary facade inspections as a matter of prudent building maintenance, particularly for buildings approaching the 13-year age threshold.
