Concrete tilt-up panels have been lifted by a mobile crane into position. Chemset bolts have been installed in the concrete panel and slab. A strut or temporary brace is fixed to the slab and wall until other structural elements have been installed and the wall can safely be unbraced.
Chemset bolts nuts are removed followed by the brace. The remaining bolt in the slab can be hit with a hammer so that it dissapears into the slab and later the hole can filled with concrete.
Formwork is used to shape and mould the concrete to the desired shape. When the concrete has reached th MPa specified by the structural engineer the formwork can be removed.
This formwork has a plywood face to make the concrete finish smooth. A top and bottom kicker with studs in between have also been used. A brace has also been used to help resist pressure from the concrete. The underside of the formwork consists of a bearer which supports a joist and joist which suports the plywoof base.
Reinforcement for the slab has been installed by steel workers. Vertical bars are also in place awaiting the installation of the columns.
The lift shaft or core of this building is erected first. The core is used to stiffen the struture and all floors will be fixed to it.
Different types of formwork can be used to form slabs. In this case bond-deck has been used.The fromwork below will be removed and the bond deck will be visible from underneath.
Plywood formwork is used to shape the slab. The void barier and steel mesh have been placed in position. Steel for the columns have been put in place. Vertical bars have been positioned so when the slab has been poured they will remain exposed ready for the column concrete and reinforced steel to be installed to create the round column.
