true, you may not know, you drill the wrong point and cause the whole building collaspe.Originally posted by ditzy:Must be careful where you drill, make sure its not a beam or something, buildings have fell because someone drilled the wrong hole.Also, certain areas of the flat is best left untouched, unless you don't plan to sell it in future. Your buyer will point it out to you, and ask for a big fat discount.

You forget to add, you need to be certified and qualified technician to do such a job, if not hire oneOriginally posted by Ponders:Need to apply drilling license to HDB first.
You must use a type approved drill with PSB sticker.
The drill bit must be certified masonry bit by PSB.
The bolt you want to use must conform to BCA regulations.
since you are drilling ceiling, you using ladder, ensure this are safety certified.
