The formwork used for the first concrete pour of this concrete bridge abutment.

The red “spreader timbers” were also used to support the template which will leave the required penetrations for the Structural Bearings (also called bearer pads, bearing pads, bridge bearings). The Bearer Pads will fit neatly into these penetrations which will then support the bridge spans.

Concretors could not be hired for this job because Turner River Camp is only a small 70 person camp and all dongers were full. For this reason, the three formwork carpenters were required to do the concreting jobs as well.

Concrete poured into four tread stair formwork and the formwork has just been stripped by the formworkers. It looks like these stairs might need to be patched up in order to fill in all the air bubbles on the surface of the concrete, but other than that, a job well done.

Four concrete forms held together with Column-Clamps and held down with spaghetti nailed plywood. The 700 mm long bolts took a bit of work to cast in due to the extra reinforcement steel positioned exactly in the center of the pedestal.

Pedestal Formwork Ready For Concrete

This job was not as bad as the nightmare pedestal, but still took extra time because the formworkers had to reposition the steel in order to fit the bolts in.

To ensure the correct heights, the concrete and bolt-top heights were established from a known benchmark with a Laser Level instrument and not by just measuring up from the foundation concrete.

Formworkers Ed and Rami at Prominent Hill Mine. 99% of the formwork construction jobs are now complete so Ed and Rami will fly-out today. A couple of formwork carpenters remain to do “shits and bits”, odd jobs etc.

This four tread stair formwork is held together with 4 z-bar bolts, held down with pins at the front and wedges (to the structure) at the back, and braced with one timber on each side and two timbers at the back.

Four verticle plywood cleats were also added to the back corners to prevent the rear concrete form from blowing out.

This 80 tonne pre-cast concrete bridge span is being placed onto the headstock and concrete embutment by a crane parked in the dry (at the moment) Turner River bed. The river floods once a year during the wet season which everybody was hoping would not arrive until the bridge is finished.

Turner River Bridge Span

The bridge span arrived by rail on the existing track. The crane was positioned on the river bed in between the old existing bridge, and the new under construction bridge. After a few scares, the bridge was completed before the river flooded.
