Massive concrete pours start this weekend at the Acute Services building, Christchurch Hospital

Friday July 24, 2015

​​concrete2-220x147px-news.jpgChristchurch Hospital's new Acute Services Building site is being prepped for the first of eight massive concrete foundation pours. 

The first pour starts just after 1am tomorrow, Saturday, 25 July, with 1200 m3 of concrete laid to a depth of one metre.

David Meates, Canterbury DHB chief executive says the pour will swallow up 300 truck-loads of concrete over eight hours of continuous delivery and pumping.

"All is tracking well for the first pour on Saturday, which is enough to fill 7500 standard bathtubs – quite remarkable when you think of it that way," Mr Meates says.

It will then take another day and a half to smooth and level the concrete. 

"Each of the eight concrete pours will be done over a weekend to minimise disruption to the hospital," Mr Meates says.

"One of the later pours will make the record books as the largest continuous concrete pour by a single contractor ever undertaken in the South Island.

Mr Meates says it will be exciting to see the building start taking shape once the foundation works are complete.

Fletchers Construction won the tender for the foundation and workers have been busy on site since June, laying damp-proof geomembranes, tying reinforcing steel and constructing the building's lift-shaft pits.

Having also worked on the large concrete pours at the Justice Precinct, the Fletchers team has been quick to apply their learnings to this new project.
