Double Wong Foundation Pte Ltd was established in Year 2000 and the main strength of the Company is in
its foundation works especially in Earth Retaining System such as Secant Piles, Contiguous Bored Piles and
Complex Combination of Retaining Wall System.
The Company has developed and continue in developing new technique in Bored Pile Foundation Works
especially Boring and Coring into Rock, Rock Drilling has since become our Specialty. The Company has in
the year 2008 establishes a new drilling technique in coring into hard rock of G1 and G2 using our modification
of core bucket fitted with Tungsten Carbide roller bits and collecting rock samples intact within the core
bucket (See photo in Appendix). The new technique highly enhances the drilling standard in Singapore and
has also bring the rock coring technique to a new level. The new technique has the advantages of vibration
free, less dust, less noise which translate to a more environmentally friendly technique that is more
acceptable in today’s Singapore which is so densely built up.
As a move to support the Building Construction Authority of Singapore in promoting more environmental
friendly in Singapore's Construction Industry, the young fleet of boring rigs we have procured since Year
2007 uses Green Engine which conforms with the latest Tier-3 emission requirement for European and
American Standards.
