How engineers inspect buildings for structural defects in Singapore

AI-summarized · Neutrality-checked

The Singapore Building and Construction Authority (BCA) utilized a combination of physical inspections, drones, and AI-driven image analysis to assess the structural integrity of over 7,000 buildings annually between 2023 and 2025. Engineers examined critical components like foundations and facades, identifying structural defects in more than 600 buildings per year, while finding that 91 percent of inspected buildings had no or only minor issues. Experts like Senior Principal Engineer Lee Hon Leong noted that tools such as borescopes and drones allowed for the identification of deep-seated problems, such as corrosion or water ingress, that were not apparent to the public. These systematic inspections served to identify and mandate repairs for potential hazards, such as falling debris, before they escalated into serious structural failures.

Consequences

Building owners identified with serious defects will be required to undertake recommended repairs to mitigate risks like falling debris. The continued integration of AI and drone technology will likely increase the efficiency and reach of future periodic inspections across Singapore's building stock.
