From Christmas Day, anyone driving down Albert Street between Swanson and Customs Streets, is suspended up to 16 metres in the air.
Underneath your wheels, bulldozers, diggers and shotcrete workers continue to build the City Rail Link.
201 concrete slabs just laid in Albert Street for CRL put together weigh approximately 1339 tonnes. That’s equivalent to about 1860 cows or 335 elephants!
CRL contractors Connectus, the McConnell Dowell - Downer joint venture, have just installed the last of those 201 thick concrete slabs that form the construction and public traffic deck along Albert Street.
This deck allows the team to continue building the future CRL rail tunnels while Auckland’s Albert Street traffic keeps moving.
This is an unusual road.
The road is 3.2 metres wide and 350 metres long, the trucks carrying spoil out of the City Rail Link trench tread carefully. It’s solid concrete, not tarmac and gravel. It consists of 201 thick reinforced slabs edged in steel, welded together side by side. The slabs were designed by the Connectus joint venture team, formed by Wilsons Precast Concrete, and each one safely craned by Crane & Rigging Services Limited (CRS LTD) into place.
This concrete slab road is suspended over the trench by steel struts and beams, while the Gleeson Civil excavation crew complete the dig and the tunnels for the City Rail Link are formed. The slabs are supported by 68 horizontal struts and 155 supporting beams.
The road held the 55 tonne crane with ease during construction.
This concrete slab road will stay in place until late 2018 when the tunnels are completed, ready for the new landscaped road design.
Aaron Ghazal, Connectus Site Engineer says: “It’s a great achievement for the team and another milestone reached for the City Rail Link project. The team worked really hard. It took about seven months to complete the construction and public traffic deck, which includes the pre-works, digging and removing the top 1.5 metre of the road and protecting services.”
Why do it? Chris Powell, Connectus Project Director, says: “It was the safest and best way of excavating, building the tunnel and keeping traffic moving as a consenting requirement.”
