It depends on many factors.

Aluminium formwork usually take around 7 days circle per floor for typical floor.
To judge whether a condominium project is on time or not maybe one can calculate is such a way,

From the SPA VP date, minus 4 month for getting CCC after CPC, then minus 8 months for general architectural works.

Then use this date minus current date, this will be your total month to carry out the structural works. Then use this period divide by total story of your condominium, that will let you judge how many days in average are needed per floor in order to deliver the project on time.

But some floor will take longer time to complete, such as the podium, 1st typical floor, transfer floor, non typical floor and etc.

Hope this help.

i been told some projects can goes as fast as average 4 days per floor,

maybe they during concrete setting time they can do all the  rebar and formwork installation for upper floor...

those in china you mean precast system? sure fast lor.... but malaysia not cost efficient yet ler...

have done 4 days cycle for approx 17k sf floor plate previously.
shear walls all around no less and no brickwalls.

but not every floor also achieve 4 days cycle lah.
