In 1966 Hansen Yuncken won the contract to build AMP's headquarters in Adelaide's King William Street, designed by architects Woods Bagot ($6.693m).
Hansen Yuncken continued to pioneer new construction methods in the 1960s, particularly on the Communications House in Mebourne and AMP Adelaide projects, where it deployed two newly purchased Favco tower cranes. With the ability to extend themselves upwards as required, the cranes were particularly useful on tight city sites with limited ground space, where they offered many advantages over the older stiff-legged type. These two projects also boasted the company's first passenger hoists on multi-storey construction sites, and new concrete pumps, all of which demonstrated Hansen Yuncken's willingness to embrace new technologies.
