I think steel bars got diferent grade.. even same number (cannot remmber we use Y16 or what). Insist on using the rough type (the cheaper type of steel bar smooth smooth one - not so strong). I also wonder, whether he really use pukau, bcz my cousion says, very difficult to find nowadays. For simple extension, no need to go use pukau he says, he shld know becz he is a QS lah. A fotting is cukp, dip about 4 feet hole, put in the steel bars, etc. My contractor than use a super long steel bar to place along the paramete, then pour the cement, and it is done!!
If u paying for the mangrove pling, make sure u see that this is really used.

Actually not I want to know their true cost but just find it strange that all the contractors who quoted me provide zero breakdown on this portion but they can provide breakdown for labour+material for floor tile, break the wall cost, move the door cost..etc. So I suspect this portion they make the most profit as no breakdown mean that is the area they don't want u to know...

Just google and u can find out how much material is needed. As for workmanship, u can estimate RM80 per workman per day. What I observed is, putting up bricks is very fast job... usually, contractors quote big big sum for hacking, but if u get in a worker, he can finish the jobb in 3 days. Even if u get 2 guys to come in, it still cost u max RM500 workers pay, then alam flora bins maybe a few hundred, so it means to hack n clear alot of stuff only cost u RM1k. But the contractor will quote 5k or more. Actually my reno quote of 200k, 20k waas for hacking.
