I'll just talk about the main structure going up now.
The white crane is a Favco 1500. The yellow tower crane is the formwork contractors "Mitcon's" crane.
The decks are catching up to the core now, haven't poured the core since late September, but will soon. The cycle is ruffly 14-18 days for each floor. It is constructed in two pours, East is pour one and west is pour two, with construction joint running N-S eiter side of the main core. We pour the slabs, core and columns with boom concrete pumps and the columns get poured with a skip occasionaly.
Each floor is more complex than normal to construct. The decks are off form, the soffits are to be exposed so the formwork needs to be spot-on and clean before pouring. There is post tensioning used along with conventional reinforcing. Also, there is geothermal pipework in the slabs (this helped gain some green star points) to reduce the load on any airconditioning. Since the soffits are exposed, there is no suspended ceiling. So where will all the services run? Under the raised floors to be done by ASP.
The main core is to house toilets, the two cores either side of the building are stair shafts made of precast concrete panels, and the lift shaft is in the precast shaft in the South West cnr where the link to Eng Nth is.
There is to be some High Voltage electrical works for ETSA to occur over the christmas period.
Yesterday, Worksafe SA just visited the site and stated it was going to be their new benchmark or measuring stick for safety in the SA construction industry.
Something for Hindmarsh to be mighty proud of.
Any questions I am happy to answer.
