Standards and Testing Division

The Standards and Testing Division undertakes applied research and development work for the production of geotechnical standards and provides testing services. The research and development work is carried out in-house as well as in partnership with universities, consultants and contractors. The Division comprises six Sections, three of which are responsible for the production of geotechnical standards and the other three operate the Public Works Laboratories (PWL).

The Division has been providing essential technical support to the Landslip Preventive Measures Programme and the post-2010 Landslip Prevention and Mitigation Programme. This includes development of prescriptive measures to improve existing soil cut slopes, rock slopes and retaining walls, technical guidelines on landscape treatment of slopes and retaining walls, techniques for automatic acquisition of groundwater data, improved methods of obtaining undisturbed soil samples, design approaches for landslide debris-resisting barriers, non-destructive testing methods for determining the length of installed soil nails and the integrity of grout sleeves. It has also been undertaking research on development of quantitative risk assessment techniques for landslide risk management, assessment of natural terrain landslide risk, slope greening techniques, behaviour of soil-nailed slopes, properties of saprolite and loose fill, relationship between rainfall and landslides, and properties of construction materials.

The Public Works Laboratories (PWL), which consist of the Public Works Central Laboratory and five Public Works Regional Laboratories, carry out a wide range of tests on construction materials, principally for Government projects. These include tests on aggregates, bituminous materials, cement, pulverized fuel ash (PFA), concrete cubes and cores, steel reinforcing bars, timber, rubber, soil and rock, in-situ CBR and soil density, building blocks and bricks, concrete kerbs, geotextile, manhole covers and pipes, etc.

The Division promulgates technical guidance in GEO publications and GEO Reports. Up to March 2018, it has released 413 GEO publications and Reports. While many of the published documents can be downloaded from the Publications, some are only available in printed copies and can be purchased from the Publications Sales Section of the Information Services Department.

The Standards and Testing Division also operates the GEO automatic raingauge system.
