Browse Forums Building A New House 1 Jul 01, 2008 2:05 pm Because our block has a slight slope from back to front (so towards the slab) I've been advised by our independant building inspector to get aggy pipe laid across the backyard and down both sides of the house, at just below slab height.
Is this something we should get done during construction, or do ourselves later? Is there a standard or recommended distance from the slab that the sggy would be laid, or will I be asked to decide this for myself? Building in manor lakes 2008 Re: agricultural pipe 2Jul 01, 2008 2:44 pm Your builder should have included that in the design if it is required.
Not knowing the specifics it may be a marginal call which is why the builder hasn't put it in (OK I may be being generous to the builder)....you're better off getting the builder to do it as it needs to be trenched, plumbed, backfilled, and drained away from the house. I'd ask the builder why they don't think it's required. mmm....donuts Homer Simpson 1956- Links: Site Costs Ready Reckoner | H1 Addiction Medical Advice | Château TDL: The Backyard Re: agricultural pipe 3Jul 01, 2008 3:02 pm I agree with TDL. If it's important enough for an Engineer to bring it up, I'd put the onus on the builder.
In our case a retaining wall was required, and the builder included the construction cost in the site costs. Cheers Re: agricultural pipe 4Jul 01, 2008 3:27 pm rang the SS.
He says it will be a lot more expensive for them to do it, and I should wait til laer in the build process, or after we move in, and get a plumber to do it? I've just looked at the site report which lists the block as 'basically flat' though not flat enough that a cut wasnt required.

How mucha re they cutting? no idea (surface floaters are mentioned, not sure if thats relevant) just the SS was surprised when he saw the plans indicated one, but the BI said the land was obviosly sloped in towards the slab and being reactive clay with poor drainage we should give it some help.

Slightly confused, your saying the plans indicate that there should be a subsurface drain, but the SS hasn't arranged for one to be put in. That means he's constructing something "not as drawn" and has excluded something you have already paid for as part of your site costs. Or am I missing somethink? mmm....donuts Homer Simpson 1956- Links: Site Costs Ready Reckoner | H1 Addiction Medical Advice | Château TDL: The Backyard Re: agricultural pipe 10Jul 01, 2008 4:30 pm plan indicate a cut, but the SS appeared surprised by this.
I've just looked at them again. Im not able to scan anything but as a general idea it says 'cut at 10.5' the back LH corner is 10.62, back RH corner 10.84 the front LH corner is 10.00 front RH corner 10.15 and it gradually increases front to back.

Block is about mid-30 metres long? Not much of a slope which is not surprising, Manor Lakes is relatively flat....I'm with _Al_ now....by the time they muck around on site you won't much in the way of defined fall, particularly in your backyard if they cut to 10.5 it's 100 mm to 200 mm elevation difference to the back fence and then the slab is built onto the 10.5 level so the slab is higher up again At the end of the day the builder has to sign off on it....you could check with them and confirm that their designer/Engineer has checked that a drain is not required. mmm....donuts Homer Simpson 1956- Links: Site Costs Ready Reckoner | H1 Addiction Medical Advice | Château TDL: The Backyard yep sounds good make the footing bigger to to allow for the pipe in the middle 3 7326 Plumbers 'can be' plumbers, made all the worse by self certification which the building surveyor invariably accepts as proof of compliance!
