Your Guide to Periodic Structural Inspection (PSI)

At ML Facade Inspection, we want to help you understand the importance of Periodic Structural Inspection (PSI) for your building in Singapore. This guide covers common questions about PSI. For more details on our services, visit our dedicated PSI page: ML Facade Inspection – Periodic Structural Inspection (PSI). For detailed regulatory advice from the BCA, you can always refer to their guidelines for structural engineers.

1. What is Periodic Structural Inspection (PSI)? PSI is a mandatory inspection to ensure the structural integrity and safety of buildings. It involves a thorough check of the building’s structural elements to identify any defects or signs of deterioration that could compromise its stability.
2. Why is PSI important? Regular PSI helps detect potential structural problems early, allowing for timely repairs and preventing serious issues that could endanger occupants and the public. It ensures the long-term safety and stability of the building.
3. Which buildings require PSI? PSI is generally required for buildings that have reached a certain age, as specified by the Building Control Act. This typically includes older buildings that need regular checks to maintain safety standards.
4. How often is PSI required? The frequency of PSI is typically mandated by the Building and Construction Authority (BCA), usually every 5 to 10 years, depending on the building’s age and type.
5. Who can perform a PSI? A Periodic Structural Inspection must be carried out by a Competent Person (CP), who is a registered Professional Engineer (PE) specializing in civil or structural engineering. They must possess the necessary expertise and experience to conduct such inspections.
6. What does a PSI involve? A PSI typically involves:
   • Visual inspection: A comprehensive visual examination of all accessible structural elements, including columns, beams, slabs, and foundations.
   • Non-destructive testing (NDT): Utilizing techniques like ultrasonic testing or rebound hammer tests to assess the quality of concrete and other materials without causing damage.
   • Load testing (if necessary): In specific cases where concerns arise, controlled load tests might be conducted to verify the structural capacity.
   • Review of structural plans and documents: The inspecting engineer will examine the building’s original structural plans and any past renovation records. We can assist you in searching for and purchasing structural as-built plans.
   • Detailed report: A comprehensive report outlining the findings, identified defects, and recommendations for necessary repairs or further investigations.
7. What happens after the PSI is completed? After the inspection, our appointed Competent Person (CP) will submit a detailed report to the BCA. If any defects are found, recommendations for rectification will be provided, and building owners are responsible for carrying out these repairs.
8. What are the consequences of not conducting PSI? Failure to conduct mandatory PSI can lead to penalties, fines, and legal action by the authorities, as it poses a significant risk to public safety.
9. Can ML Facade Inspection help with PSI? Yes, ML Facade Inspection provides professional PSI services, with our expert team of experienced and BCA-approved Professional Engineers. We apply cutting-edge engineering principles to ensure your building meets all regulatory requirements and remains structurally sound, offering enhanced safety, peace of mind, and protection of your asset value through early issue identification and tailored maintenance planning.
10. Do we do remedial work after PSI? While the PSI focuses on inspection, if remedial actions are needed after the inspection, the property owner should hire a contractor to perform the repairs. We can advise on the types of repairs needed.
