currently my flat is doing reno.

according to constructor, they will plaster the wall after air-con piping done, is this true (or they wana save some material)?

I am wondering, if next time we remove the pipe trunking (relocation etc), then the wall will look ugry?

well, you can look at it in two ways...

one, the want to be able to fill out any gaps between the trunking and the wall during plastering.

two, they want to plaster and paint without any delay or interuptions from the installations of the trunking.

should they plaster first, and the air-con men scratch/damage the wall/plaster, then they have to plaster all over again, cos the trunking will require some minor hacking and nailing of plastic trunk to the wall.

should they plaster first, the will still have to do a second round of plastering to touch up the gaps between the wall and the trunk... this will mean additional man hours == more cost.

So it is quite reasonable for them to request for plastering to be done after the air-con trunking is done to be more cost effective and efficient

my two cents

Thanks...is this the common practice ?
