161 Clarence St

We were contracted to link a series of shopping levels on Clarence St together with a spiral staircase. Our initial plan was to cut a semi-circle for the staircase, but previous concrete works had encased the central pole. We adjusted our strategy to cut 2 semi-circles with a Circular Wire Saw and join these cuts together with Wall Saw Cuts to create a half donut shape. Ultimately this decision was advantageous as it ensured that the staircase would retain the maximum level of stability.

The complete process required a combination of services including Circular Wire Saw cuts, Core Hole Drilling, Wall Sawing and the operation of a Gantry Crane, in order to cut out the shape and lower it down 4 meters to the level below. Afterwards our team used our Weka Hi-Frequency handsaws and ring saws to cut down the offcut blocks into manageable pieces for disposal.

Additionally, at the conclusion of the project, we cut a 2 meter x 1 meter Peno to allow access for air conditioning to be installed.

These works took 2 Diacore expert operators a total of 2 days to complete.
