Hole lot of digging to do on the Riverbank
ONE of the biggest earthworks contracts in the state’s history has been awarded to dig one of the biggest holes Adelaide has ever seen – for a five-storey carpark beneath the Riverbank.
Walker Corporation has handed a $30 million contract to national civil contractor Delta Group as part of its $500 million development of the Festival Plaza precinct – now known as Festival Square – which will deliver the new carpark, public and arts spaces and a controversial office tower.
A 1600-space, five-level basement carpark will be the focus of the contract, which has resulted in Delta opening an office and yard in Adelaide.
Delta will drill 15m underground to remove an estimated 130,000 cubic metres of material over 14 months.
Walker Corporation South Australia senior development manager Ben Moore said that would ready the site for the construction of the carpark this year.
“We only started work in May of last year when we were formally provided access to the site, so it’s been a very busy work schedule since then,’’ he said. “The demolition (of the old plaza) and excavation process is literally huge, it’s creating an enormous space that is starting to give a sense of the scale of the development.”
“In some ways, it’s a pity that the hoardings prevent people from seeing what’s happening. I think they’d be quite impressed.”
Negotiation over the longawaited carpark was one of the major sticking points that delayed SkyCity’s decision to proceed with a $330 million expansion of Adelaide Casino.
In 2017 The Advertiser revealed tycoon Lang Walker had struck a deal with SkyCity for the casino operator to lease 750 spaces in an expanded car- park. The plaza redevelopment will create 10,000sq m of public space modelled on city squares such as Plaça Catalunya in Barcelona and Leicester Square in London.
A 23-storey tower with 40,000sq m of office space will rise between the casino and Parliament House, and a commercial area will have cafes, restaurants and shops.
The expanded Adelaide Casino will have a 123-room luxury hotel, three bars and three signature restaurants.
