The first site we visited is currently under early construction, part of the soils are still in digging process. However there are shotcrete walls could be seen, Shotcrete is concrete conveyed through a hose and pneumatically projected at high velocity onto a surface, as a construction technique (Wikipedia, http://en.wikipedia.org/wiki/Shotcrete) The shotcrete wall on site is about 10-12 storeys high. There is also a precast concrete retaining wall and some reinforcements cages on site.
Shotcrete wall
Reinforcement cages Used to increase the strength of concrete, might be used as water tank or piles.
Bar Guards Yellow plastic end caps used as a protective device for reinforcing bar.
The major site we visited on Friday was the Royal Melbourne Hospital; we walked under the bridge which will be linking the Victorian Comprehensive Cancer Centre (which is under construction as well) and the site. Since under the protocol we weren’t allowed to take photos on site, I only took one picture of the bridge from outside, standing on the street. The budge of this building is around 100milion to 120 million overall, and the VCCC is one 1billion big project cross the street. 3

On the street level of the hospital, we went into a nearly done courtyard area; we were told that there is 26 in situ piles support the structure. Precast concrete panel could be found on site due to its well-manufactured technologies. Moreover, one existing wall is built by bricks, weep hole could be identified on the brick wall, as the building might contain a lot moisture, it’s really important that the structure to be waterproofed and allow spare moisture to move out and evaporate.
Sketches are coming up.
We then access the site through the Private Hospital and went to the 4th floor, followed the original path to the site, we firstly saw the new roof which is going to be lower than the original one.
We also notice that the girders above the head were sprayed by concrete but the joist weren’t, which means that secondary member doesn’t need to be protected.
As we went higher, steel strut as the framing of the wall which separates each room could be seen, also, like timber framing, noggins made of steel were also holding spacing between each strut. In addition, most steel on site is cold-formed steel with a shape of PFC.
Some wards have foam core panels, due to it’s ability of absorb the sound and create the quiet atmosphere in the hospital.
