With one of the larger classroom blocks identified as a potential earthquake risk, like most seismic strengthening projects one of the first obstacles was establishing a suitable foundation design to fit around the working space restrictions the existing building offered.

One of our Low-Drill units was squeezed into extremely tight areas outside the building to install 900mm diameter bored concrete piles against external walls for the K-Braces, while a small bobcat was used with one of our rotary drilling attachments to fit through the 1300mm wide access way and install the 200mm diameter micropiles, 18.0m deep.
