While I did not opt in to it, the OCS component for flooring of a 5rm BTO was quoted as $6100, although that was in 2012. So agree with McMoo that we should try to find quotations somewhere along 7-8k, with assumptions that only the price of screed doubled but not the tiles themselves. Seriously, shouldn't price of a pack of pre-packed screed be standardised? And as for labor, doesn't all involved in tiling works go through the same course in BCA?
