  • Laboratory and on-site testing services

    The services below are available in Hong Kong :
    • Physical testing of construction materials
    • Foundation and geotechnical testing
    • Non-destructive testing on concrete, welds and steel
    • Functional and durability testing of building components
    • Chemical analysis of construction materials (e.g., concrete, cement, aggregate and steel)
    • Calibration of construction materials testing equipment and other equipment
    • On-site building diagnostic testing

      • Building Diagnostic Testing

        To facilitate the implemenentation of the Manditory Building Inspection Scheme, HOKLAS-accredited laboratories are providing the following building diagnostic tests to help registered personnel in obtaining objective evidence on building conditions such as concrete strength, water seepage, corrosion and spalling concrete to ensure building safety:

        • Carbonation test
        • Chloride content determination
        • Covermeter survey
        • Half-cell potential measurement
        • Infrared thermography
        • Resistivity measurement
        • Surface hardness measurement
        • Surface penetration radar survey
        • Ultrasonic pulse velocity measurement
  • Inspection Services
    • Assessment of welding procedures in construction projects
    • Inspection on production of construction materials (e.g., waterworks and paint)
    • Indoor air quality measurement and inspection

      • Indoor Air Quality Measurement and Inspection

        To improve indoor air quality (IAQ), a voluntary IAQ Certification Scheme is being administered by the Environmental Protection Department. IAQ inspection bodies provide the following measurement and inspection services for the IAQ Certification Scheme :

        • Walk-through inspection of premises/buildings
        • On-site measurements of 12 IAQ parameters (e.g., air movement, carbon monoxide and volatile organic compounds)
        • IAQ compliance assessment

          More information is available on the website www.iaq.gov.hk
