Regarding the tolerances guide this is a link to the pdf online to download it:

The builder must comply with these tolerances! It pretty much is the building code for dummies so anyone can make out what is acceptable and what isnt.
Are you able to forward me a copy of the propsed plans for future westernport hwy changes?
Thanks for the other link - greatly appreciate it.
