[U/C] Re: M2 North-South Motorway

I am just curious why they wouldn't have just continued the tunnel in the middle as its only some 2-3kms? They could have joined stages 1&2 by tunnel to save a lot of above ground disruption to traffic while its being built (as well as property resumptions etc). So that drivers not driving the full...

[U/C] Re: Flinders Rail Link

Unless upgrades or additional tracks are created between Woodlands Park and Goodwood, I think the proposed stopping pattern is a fair compromise given the lack of overtaking tracks. Making Flinders stop all stations and Seaford express would likely result in the express services being stuck behind t...

[U/C] Re: M2 North-South Motorway

I can't remember where I saw this, but I have seen some unique grade separation projects which involve putting traffic in one direction through a cut and cover tunnel, and then putting traffic in the opposite direction on an overpass which sits directly on top of and is supported by the tunnel struc...

[U/C] Re: M2 North-South Motorway

There's not much point comparing tunnelling costs with Sydney or Perth as they have totally different geology to Adelaide. Melbourne is the most similar to Adelaide with clay soils prominent in most the urban area.

[APP] Re: 73-85 Pirie Street | 89m | 22 Levels | Office

I noticed that some of the contracts are starting to be awarded on this project - also looks like the building has been shaved down slightly to 21 levels (ground level, 3 car park levels plus 17 office levels) from the original 22 by Cbus. Don't think a contractor has been appointed just yet, but I ...

[U/C] Re: Penny Place | 78m | 24 levels | Apartments

Apologies if this is a dumb question.... but why don't we see a core box or two above the levels on this one like in most buildings? I'm interested to know. I suspect that the lack of a jump form (core box) on this site is the result of the building's longer and narrower profile compared to other h...

High water table would not prohibit a tunnel from being constructed - there's plenty of tunnels constructed in locations with high water tables and drainage systems to suit.

[U/C] Re: 269 North Terrace | 118m | 36 Levels | Student accommodation

Technically the correct term is a jump form, but it's also referred to sometimes as core boxes. It's a scaffolding system used for the main core walls (which house elevators and building services, typically, and also provides the building with a significant amount of it's structural capacity), hung ...

Doesn't CLT have fire resistant properties too?
CLT does have fire resistant properties... the outside chars (sacrificial) and protects the inner layers when subjected to fire.

The $50 million cost may just be the cost of the "shell", and not inclusive of building services and other fitouts.

[U/C] Re: North-South Motorway

The problem I have with a huge bridge or tunnel is they just keep costing money forever. They are not permanent structures. Constant checks for cracking and movement. What is the expected life of the superway? I imagine it will degrade over time to the point that it probably needs to be entirely re...

[U/C] Re: North-South Motorway

Demo’s will continue all this year (ie Croydon Kings soccer club has until the end of their season before they need to vacate). I think construction is from early 2020 and take until the end of 2022 for completion. The main job is the overpass. It will be interesting if they assemble a bridge/overp...

[U/C] Re: North-South Motorway

I can't quite tell what the set up is here - is there a piled wall behind the retained slopes, or is this shotcreted wall the only thing supporting the surface road above? From what I can tell, the wall in question is an unreinforced shotcrete sloped wall which relies on gravity (i.e. it's own weig...
