Sustainable Construction of a Bored Pile Foundation System in Erratic Phyllite
This paper highlights a case study involving the construction of a cast in-situ deep foundation system supporting a large manufacturing plant in suburban Kuching. The site is thought to be influenced by contrasting geological properties of the Padawan (mainly sedimentary), Tuang (mainly metamorphic) and Quaternary formations. Localised moderately-strong sandstone and andesite rocks sometimes laminate the more dominant but erratic metamorphic phyllite. The design of cast insitu bored pile foundation system requires necessary local experience so as to provide optimum pile socketing lengths to minimise carbon footprint as bored pile construction has been found to be the highest contributor of CO2 compared to other ground improvement-styled foundation systems.
