This existing carpark building was seismically upgraded in 2003 to allow the construction of 5 stories of apartments to be built on the top of the carpark. Wallace was involved in the construction of new 300mm thick Shearwalls built between existing concrete columns, Insitu concrete walls poured against existing concrete walls with scabbled and epoxied starters. Concrete columns and foundations were strengthened and a new 8m long shearwall was built 2 floors high on the top of the carpark for the new steel and timber apartment structure. All of this work was undertaken without the closure of the carpark.
