Builders position downpipes at the end of walls for aesthetics, not good design.
A hipped roof has small roof areas at the end of walls. When downpipes are positioned at the…

Yes, it is the homeowner's 2 part post handover protection. I have seen forum photos with waterlogging all along a path's outside barrier which isn't good. Just need the builders…

We're going around in circles here. Just read what I pasted from the NCC.

I think that the CSIRO ducument states a 1:60 fall (17mm over the first metre). There are thousands of slab heave victims that were given the CSIRO document by their…

Are you sure it is heave and not subsidence?
The trees being on common property really needs proper legal advice as to responsibility.

Page 2, bottom of the do's. They say 70mm, not 75mm. Oops! It is a good document, well worth a read.

There is a lot of confusion because there are so many unlegislated guides stating different things...as per the VBA. I'll look for it later and link it.
Re the concreter, their…

The VBA states 75mm over the first metre away from the house but it is not legislated. 75mm over 1 metre is quite a slope and one that many would…

Geo techs are credible engineers and tree roots don't have to go under the house foundation to cause uneven moisture levels. Google matric suction to understand this natural phenomena.

Drainage is your only option in QLD and the path will work wonders.

All sounds good to me. Where will the ag pipe drain to?

The VBA media release below emphasises a legal requirement that might also interest you.

The forum search facility is a great asset.

Do a forum search using the term "pre contract consultation". There have been many discussions.
The thread below and the links is a good place to start.

Are you referring to a storm water pipe or a surface stormwater drain?

ORGs are on drain pipes, not stormwater pipes.

This is covered under AS/NZS 3500.3.7.2.7 (j) and also AS/NZS 3500.1.5.3.6 (ii), both of which state a minimum 100mm separation.

Regulations are applicable to the distance between the finished surface level and the DPC. Various sub regulations exist applicable to the area's ARI and whether the finished surface is in…

Actually, the building inspector they work with does a lot of the work but builders love having the certifier in their pocket, the reason why there is now so much…

The nearest drain will collect surface water but you confirmed that it drains grey and black water. If it does, it is highly illegal and you can't leave it like…

The domed one is an ORG.
Was the surface drain (nearest pipe) already there? I am wondering whether the concreter has illegally tapped into a sewer pipe to connect a…

Were both stand pipes already there pre path? The ORG (domed cap) would have been there at least.
The water you describe in the domed grated pipe will be a trap.…

The domed cover is the ORG. There had to have been a reflux valve fitted in the sewer pipe because of the ORG's height. Not sure that the VBA would…

We can only give generalised overviews, you need an expert onsite. insider knows your area very well.

Where are you located?
Do you have photos of the pipes during the build?

Houses also settle. Cracks don't always mean heave.
