GDA was engaged by the earthwork contractor to design Cantilever, Anchored contiguous pile wall for approx. 464m of wall as well as 3 crane bases piles and foundation piles on the adjacent road. GDA have used latest state of the art software packages to design the retention wall and foundation piles. GDA also provided drawings and full drafting services.

GDA was engaged by the piling contractor to design and certify 294 nos of 450-1050mm diameter piles. As part of GDA scope, we carried out 6 PDA tests on production piles to justify the geotechnical parameters assumed in the detail design. Tests results were satisfactory and a useful tool to reduce time and cost for the client as well as helping environment using less materials
