High rise has a number of constraints

These can be broken down into several key factors

1) foundations and substructure
2) superstructure
3) Cladding
4) fitting out
5) handover cycle

You at the moment appear to be focussing on the structure and particuarly say cranes and pumps.

Looking at cranes first what Andrew says is pretty much there but I would add another couple of factors.
1) what the vertical elemnt formwork looks like. In the case of cores is it self climbing and in the case of columns where are they stored and erected this all requires crane time
2) the possible locations for cranes will they self climb within the building or will they be fixed to the external elevation, there will be a limit on how many you can locate on site.
3) whatever you do I would recomend that you have complete floor plate coverage with your cranes to minimise cycle times.

On the pumping side you need to start with access to the discharge point for vehicles. No point having 10 pumps if you cant feed them. Topside you should look at placing booms which can be located where they will be required. Also you need to look at how you place concrete in the verical elemnts if you can do it with pumps that releives the crane.

Finally look at how you move your formwork, will you have a formwork hoist, or tables or tradditional it will all add onto the crane requirement if you are not carefull.

Cycle times can often be determined by the logistic support facilities but also there is a limit due to the structure and curing timethis helps.

By the way we get down to 4 day cycles here in HK or below and I did a job in Abu Dhabi in the mid 80s where we were down to 2 plus

Who are you working for?

I have worked in Dubai and Abu Dhabi.

I too would be interested to know the answer to your question. Never planned a high rise building before.

What’s it like planning for the oil & gas sector? What jobs have you worked on in the oil & gas industry?
