Which buildings need inspection?<\/h2>\n

[\/et_pb_text][et_pb_text _builder_version=”4.25.2″ _module_preset=”default” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]Building inspection is analogous to a health check-up.<\/strong> Although you are not sick, you should have a physical examination at least once a year; this helps you to get instant treatment should any symptom develop.<\/p>\n

Likewise, a building needs regular inspections so that any defect can be discovered and proper fixing performed. This helps to ensure that the building and equipment is safe for use, and to extend its useful life.[\/et_pb_text][et_pb_image src=”https:\/\/www.at-consultengineering.com\/wp-content\/uploads\/2025\/11\/build.jpg” alt=”\u0e1c\u0e39\u0e49\u0e15\u0e23\u0e27\u0e08\u0e2a\u0e2d\u0e1a\u0e2d\u0e32\u0e04\u0e32\u0e23” force_fullwidth=”on” _builder_version=”4.25.2″ _module_preset=”default” border_width_all=”1px” border_color_all=”#000000″ global_colors_info=”{}”][\/et_pb_image][\/et_pb_column_inner][\/et_pb_row_inner][et_pb_row_inner _builder_version=”4.25.2″ _module_preset=”default” custom_padding=”15px||15px||true|false” global_colors_info=”{}”][et_pb_column_inner saved_specialty_column_type=”2_3″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.25.2″ _module_preset=”default” header_2_font=”|700|||||||” header_2_font_size=”20px” custom_margin=”||0px||false|false” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″]<\/p>\n

    Building Inspection Procedure<\/h2>\n
      \n
    1. Hire a building inspector<\/strong> who must be registered with the Department of Public Works and Town & Country Planning to inspect the building.<\/li>\n
    2. Prepare or obtain a building plan<\/strong> for the inspection, where the floor plan of every level must show the location of equipment, electrical pathways, and fire escape stairs.<\/li>\n
    3. The inspector will review the plans and related documents<\/strong> such as the building maintenance inspection reports from previous inspections, and then proceed to inspect the building according to the legal standards.<\/li>\n
    4. The inspector will prepare an inspection report<\/strong> on the building and its associated equipment for the owner. If the inspector cannot finalize the inspection result in any area, they must find a specialist to conduct a further inspection.<\/li>\n
    5. Certify the inspection results<\/strong> If the inspector evaluates the results and finds the building meets the safety standards, the owner can proceed with the next steps. However, if the building fails to meet the safety standards, the inspector will notify the owner or building manager to make necessary corrections as specified.<\/li>\n
    6. The building owner submits the inspection report<\/strong> to the civil engineer for review.<\/li>\n
    7. The officer will review the inspection report<\/strong> within 30 days. If the inspection meets the criteria and is deemed safe, a building inspection certificate (Form R.1) will be issued within 30 days after the review process is complete.<\/li>\n<\/ol>\n

      What Happens If the Law Is Violated?<\/h2>\n

      If construction, modification, demolition, or movement of a building is carried out in violation of building control laws, the local authorities will take the following actions:<\/p>\n

        \n
      1. Issue an order for the building owner, occupant, or project manager to stop the illegal action.<\/li>\n
      2. Issue an order to prohibit anyone from using or entering any part of the building where the violation occurred.<\/li>\n<\/ol>\n

        Once actions according to Item 1<\/strong> and Item 2<\/strong> have been carried out, the local authorities will consider whether the violation can be corrected:<\/p>\n
