Over the past few weeks the concrete water tank has been constructed.
It is 23m x 23m in width and 2.6 meters high.
The tank will soon be backfilled from the mounds of soil on site and works will commence to reconstruct the garden and circular drive.
The following is a series of images showing the base of the tank, forming the walls, spraying the shotcrete onto the walls, forming the roof, and finally, pouring concrete onto the roof to form the lid of the tank. 90 tonnes of steel reinforcement have been used in construction of this tank.
The tank floor has 250 cubic meters of concrete in its base

The beams that hold up the roof are 1 meter deep and 750cm wide. There are 4 beams in total, then bondex roofing secured with hardset reinforcement ties.

The concrete tank is now formed and awaits 2000 cubic meters of fill to cover it over to form the base for the new garden.

After the digger has prepared the ground, the form work and steel reinforcement are set up for the tank, with pillars in the centre to hold the trusses for roof supports.
Keep an eye out around 35 secs, when a team of people appear on site to perform one continuous pour of concrete onto the reinforcement. Each member of this team has a specific role to support the continuous pour—from holding the hose to spraying the concrete or smoothing it off.

In June and July the diggers and trucks worked through a cold Melbourne winter to dig the enormous hole required for the new water tank. As can be seen in the video, the tank will be hidden underground below the new western forecourt garden.
