Anyone reading about Guide to Standards and Tolerances would think it provides a reasonable view as to what is acceptable in domestic building construction. Nothing could be further from the truth. In reality the guide is used by builders as excuse for poor workmanship under authority from Building Commission. Have a look at this example:
The brickwork in the photo above actually complies with Guide to Standards and Tolerances . Why? The minimum perpend is 5mm or more and the maximum variance in perpend widths is not exceeding 8mm in the same wall.
The builder will use the Guide to justify this wall as acceptable because Building Commission thinks it is.
I think that the wall is a disgrace and is only good enough for rendering. I think Building Commission is a disgrace for producing a document that gives this type of excuse for poor workmanship.
Do you really think that the Building Commissioner and his accomplices that produced the guide would have this rubbish in their home? Why should you?
Hi,
I am currently building, and please forgive my ignorance, is it the vertical gap in the wall the problem here?
Cheers
