Sunway Flora project using post tensioned concrete, is this common for condo?

Good for quiet living which I enjoy.
I am looking at Tower B currently.
Determine to get it any moment soon.

Better resolution photos from Flora website.

very fast construction.
buy from reputable developer really different aura.
No need scare

Was looking around Bukit Jalil/Sri Petaling area only; I considered subsale units first but the amount of rebate I got from Flora was a lot, which almost equals to the price I get from subsales in the same area. Also considered newer places at the surrounding area like Ren Residence, Paraiso, Kingswoodz, Ayanna, Aurum but ultimately Sunway being the developer was the main attraction for me.

Right after MCO, i wemt short holiday and stayed at a serviced apartment near Gurney Drive in Penang, paid extra to stay at unit on the third highest floor. When checked out on Sunday, waited 45 mins to get to ground floor due to all crowd checked out at same time. Those on lower floors, they called for lift going up and down, and took the lifts to go up when got space, stop at every floor. By the time reached higher floor already full. Then coming down also stop every floor coz every one is calling for both up and down which compound the lift waiting time.

After that experience, all the high rise properties i went viewing, i factored in number of units/lift in my consideration.

excuse for more defect units?
