Frequently Asked Questions

  • What is the purpose of Periodic Structural Inspection (PSI)?

    The Building & Construction Authority (BCA) requires structural inspections to be carried out to ensure that the building structures are properly maintained and safe for continued occupation.

    Please see BCA Periodic Structural Inspection Page to learn more:

  • How often do I need to carry out the Periodic Structural Inspection?
    • Once every 5 years for non-residential buildings.
    • Once every 10 years for residential buildings*

    *Detached, semi-detached, terraced or linked houses that are used exclusively for residence, and temporary buildings are exempted from the inspection.

  • Is Lee Consultants qualified to inspect my building?

    Yes, we are found in the List of Professional Engineers for PSI or the Professional Engineers Board (PEB).

  • What should I do if I do not have copies of As- Built Structural Plans my building?

    We can assist to purchase plans from BCA on your behalf. Kindly fill up the Search Plans form and we will get back to you.

  • Why am I required to provide you with As- Built Structural plans before the inspection?

    As-built structural plans are required so that we can have a better understanding of the foundations and structures of your building before performing our inspection.

  • My building has recently completed Addition and Alteration (A&A) works. Do I need to inform you on that?

    Yes. Please notify us of any A&A works done on the building(s) previously. Please kindly also provide us the A&A’s Structural As-Built Plans.

  • What are the usual timings of the inspection?

    Weekdays, beginning from 10am to 5pm.

  • What arrangements should be made before the inspection?

    Before the Periodic Structural Inspection:

    1. Please let us know if you have a long ladder on site for the use of inspection. It will help us to access to critical parts of the building.
    2. Please kindly inform all tenants/ staff of the inspection’s date and time so that they are well aware that an inspection will be carried out on the day itself.
  • How long does it take for BCA to respond to our report submission?

    We will inform you on BCA’s response. It usually takes around two weeks from our PSI report submission date.

  • If there are remedial actions to be done after the inspection, what should I do?

    Please proceed with the repairs of the building by hiring a contractor to perform the remedial actions.
