LIFT SLAB BUILDING
Pouring To Start Today
A start will be made today with the pouring of about 70 tons of concrete for the first floor slab of Christchurch's first multi-storey lift-slab constructed building, the new office block for the Manchester Unity on the corner of Worcester and Manchester streets.
The lift slab method of construction involves the casting of floor slabs in layers on the ground and then lifting them into position one after the other by means of inverted jacks. The system is in widespread use overseas and produces an exceptionally fast rate of building construction. It is planned to pour a floor slab each week and to have eight floors hoisted into position to a height of about 90 feet by the middle of December.
Each floor slab is reinforced by high tensile steel cables which are tensioned after the concrete is poured by hundreds of tons pressure exerted by hydraulic jacks producing an exceptionally light, high strength-to-weight ratio structure.
The concrete is being prepared in advance at the Blenheim road plant of Certified Concrete (Christchurch), Ltd., and will be transported by agitator trucks to the site ready for the pouring to begin at 6 a.m. today.
