THE WORLD’S HIGHEST BUILDING yet to be constructed by the lift-slab method, the 210ft, 18-storey, £A2,250,000 Australian headquarters of the Royal Exchange Assurance, is being built in Sydney. Work on the site started in August last year, the first slab being lifted in March. The building will be completed in July, 1960. Compared with orthodox building methods, the lift-slab technique cuts basic structural costs by one-quarter, and the time by one-third. TOP: The irresistible attraction of construction activity is recognised by the builders in the provision of peep-holes at heights convenient for the curious, either adult or child. BOTTOM: A stanchion (or column), with jack in position. The lifting capacity of each jack is 70 tons. The total weight of concrete slabs to be lifted is 20,000 tons.
