Student accommodation and Adelaidean dispute has been decided in favour of Student Accommodation. Are these 2 buildings close enough to the Realm that the combined mass will impact views of Realm.

Of or from?

Of, would entirely depend on where you're viewing it from. I'd say if you're coming in from some angles on the North Eastern suburbs (Norwood etc) it may be impeded. Rest of the city aside from South West would have pretty decent views of it.

Sorry my bad, I was curious as to if the combined mass would adversely impact views from the Realm on the north east aspect or are they far enough way it is part of the view. Hope that makes sense. So not just Adelaidean values negatively impacted.

Bit of both, my guess based on a quick sketch.

This is an item about "Post Tension Floors" which I posted yesterday under :General development discussion" I reposted here because this flooring system is being on Realm and also on the GPO project at Victoria Square.

Post Tensioned Floors.

Post tensioning of flooring is a means of strengthening concrete floors without making the floor thicker or adding more columns to support the floor. It involves the following steps.
1. At the reinforcing stage hollow metal tubes are laid out in a grid pattern along the length and width of the floor in a grid pattern. These tubes can be either circular or a flattened rectangular shape.
2. The tubes are not perfectly horizontal but tend to move towards the bottom of the concrete slab mid span between the supporting columns and rise towards the top of the slab over the columns. This is to lift the floor up mid span and pull it down over the columns.
3. Steel cables are inserted into each tube and are anchored at one end to a metal plate with a short length (about 1 metre) hanging out at the other end.
4. The rest of the normal reinforcement is then added and the concrete slab is poured.
5. Once the concrete floor has gained minimum strength the free end of the cable is tension up with a hydraulic jack and locked in place. Hence the term “Post tensioned”.
6. 6rout is then injected into the cable tube and the ends of the cables are trimmed off and the cable anchors are finished off with concrete to match the floor edges.

Post tensioned floors allow wider spans between adjacent columns and in some cases thinner floor slabs. Note the actual jacking is carried out when no other workers are present since should a cable snap when being tensioned it could break through the floor surface.

The plans of all structures with post tensioned floors must have their blue prints marked as such so that proper care can be taken in the event of them being demolished.
The following projects are using Post tensioned floors: GPO, Realm and 179 Greenhill Rd Parkside.

(Continued from above) to the left is a roll of duct cable, plus a sack of the Flat type cable ducts and on top them the specialist reinforcement to hold the ducts at the correct level. picture at realm site .

(continued from above),
this picture by shiftaling of the GPO project shows the ducts laid out in a grid pattern.

But wait there's more, This view from !79 Greenhill Rd project shows the free end of the Ducts before tensioning.

And finally.. view of the cable anchor points (the little dark areas) having been sealed and flushed level with the edge of the floor end. (thanks to normh)

Thank you for that explanation. Either I don't understand, or there is a typo in step 2 though.

If the duct rises to near the top of the slap mid-span, wouldn't tensioning the cable tend to pull the slab down in the middle by pulling the duct towards straight? Shouldn't the duct be high in the slap over the columns, and low in the slab mid-spans, so that tightening the cables lifts the middle of the span relative to the ends?

[EBG]

Yes SBD you are right I wrote it the wrong way around in step 2 the force should be upwards in mid span so the duct is towards the bottom mid span,. thanks for checking.

So that's the ground floor we are looking at?

[normh]

So that's the ground floor we are looking at?

Yes and the dirt "corridor" to the left on which the crane is sitting is an arcade that will link to the Renaissance Arcade, the bottom right will have shops

Do you know what the dirt floor behind the facade has been left for?
