The 29-storey Condor Tower has grown, quite literally, off the back of an existing 10-storey office building, effectively recycling rather than demolishing the old structure into something economically and socially viable.According to Cement Concrete & Aggregates Australia, the building is also an example of the versatility, cost efficiency and speed advantages of concrete framing.Builder and project manager Q Con uses a range of concrete solutions and forms across the project – from precast and in situ elements to AFS walling, a proprietary system of cement fibre-board panels core-filled with concrete.The project has been profiled in CCAA’s latest issue of Concrete Concepts.
