Check this 2920 Tonne Concrete See Saw sitting on top of just one concrete pier at South Road Superway project in Adelaide.

The see saw is made up of 36 x 72 tonne Precast concrete segments and 4 x 82 tonne precast concrete segments all sitting on just one concrete pier.

The 2920 tonnes does not count the two heavy cranes (Light and Lofty) which travel and traverse along the top of the see saw, not to mention the other construction materials.

Pre-cast concrete element molds produced with design and production quality with GokerFormwork standards presents superior features with its design principles giving possibility for fast removing of mold, fast opening and closing, rigid structures not affected from concrete pressure and vibration and high surface quality.

Precasting Cone Shaped Concrete

Location: Port Adelaide SA

Precasting six cone shaped concrete structures 2 at a time for the Adelaide Aqua Port Stanvac Desalination project.

Scaffolding

The 400 mm thick bases for the concrete units was poured first and the 2600 mm cone shaped section will be added on top. After the bases are poured, the scaffolding is added to enable steel fixing, formwork erection and pouring of concrete.

Tube and Fitting Scaffold

Internal Formwork

The internal formwork is 1800 mm diameter (not cone shaped) which includes 2 x 6mm plywood layers bent into shape and screwed into the vertical timbers one layer at a time.

Cone Formwork Internal

External Formwork

The external formwork below is cone shaped. It will also be skinned with 2 x 6mm plywood layers. It will take a bit longer to screw the ply to the external formwork because of all the extra cutting into the cone shape.

Cone Formwork External

Below we see the skinned external formwork being added to the structure in 2 parts. There is no way this formwork would fit around the steel in one piece, so we split it in half, lifted it in two crane lifts and joined it all up in position.

Finished Precast Concrete Unit

Below we see the finished 30 tonne pre-casted concrete unit. It will later be placed on a barge with the other 5 units and floated out to Port Stanvac Desalination Project.

Cone Shaped Pre Cast Concrete

Plain old circular formwork is a bit easier than cone shaped formwork.
