Foundation and Geotechnical Engineering

We offer foundation and geotechnical engineering services to our Group’s internal construction projects and as stand-alone services to external clients. Our Group’s principal foundation and geotechnical engineering services cover all types of building such as residential, commercial, institutional, purpose-built or specialty buildings, and civil/infrastructure construction projects, which comprise the following core services:

  • piling solutions including bored piles; and
  • earth retaining systems.

(a) Bored piles

Bored piling is piling work to carry heavy loads from structures, where it involves boring and the simultaneous removal of soil from the ground to form a circular hole through the use of an excavating tool consisting of either a mechanical rotary rig mounted on a crawler crane or a hydraulic drilling rig. Different tools are utilised depending on the various soil conditions.

Large diameter bored piles are developed principally to cope with higher structural loads. Bored piling activities also generate less noise and vibration compared with the traditional driven piling method where the pile is driven into the ground by means of a pile driver.

(b) Earth retaining systems

Retaining walls are structures that restrain soil to unnatural slopes, and are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like basement construction and hillside slope protection. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil.

Our Group’s earth retaining systems include, but are not limited to, contiguous bored pile walls, diaphragm walls and steel sheet piled walls.
