Worcester Boulevard Multi-storey
Carpark Building
Division: Demolition
Client: Mainland Capital
Location: Christchurch CBD
Status: Completed October 2024
Demolition of a multi-storey carpark built over a live Orion substation supplying the Christchurch CBD and directly adjoining the former Rydges Hotel. A propping and cutting plan designed with the structural engineer controlled collapse risk, and cut-and-crane and high-reach methods were used to deconstruct the building in tight spaces.
Continuous vibration monitoring protected the substation and adjacent structures, and a closed-loop tank system treated groundwater so that stormwater discharge met consent conditions. The substation and surrounding buildings were unaffected, and over 98% of uncontaminated waste was reused or recycled.
