Construction of Bored Piles In Limestone Area and Friction & Point Bearing Capacity Based On Field Test (Osterberg Test)

The purpose of this research is the identify the effective modified deep foundation;
bore piling procedures on top of identifying the special custom made drilling tools
that effectively enhance a pile's quality in terms of verticality, besides reducing its
construction time and costs; in karstic limestone bedrocks. Moreover, this study will
also come out with a general normalized shaft displacement versus shaft resistance
graph for the area of Kuala Lumpur, to be used in bored pile design calculations.
Over the years bore piling in karstic limestone had always poses tremendous
challenges, not only to the contractor itself, but also been a major challenge in bore
pile designs. Hence, in order to improve one's productivity in construction, more
research regarding bored pile construction has to be done.
