Browse Forums Building Standards; Getting It Right! 1 Jun 15, 2015 3:41 pm Hey guys. We've just recently finished construction of our new home and i noticed something out of place when planning out our driveway. It seems that the stormwater pipes that lead under the house to the pit are 90mm with a 100mm collar to join with the down pipes wich are 90mm. It seems like they are trying to pull a fast one on us so I just double checked our tender and it clearly states "provide expansion couplings and 100mm (diameter) stormwater upgrade to suit soil classification. " So my question is can I do anything to get this rectified?? Are they allowed to do this kind of stuff? What would you guys do if you were in this situation? I have already instructed our bank to make the final progress payment but we have not yet had handover so I think they'll just give me some bs story and move on. Would love to hear your thoughts and opinions...

Tell them it's not to the spec. If they can prove that it has no detriment to the stormwater plan then the builder is within their rights to request a variation. To that end even if it went to VCAT it would go in their favour. The only thing they would be in breech of is not raising a variation.

Is this correct and do you know your roof area? 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.

Re: smaller stormwater pipes then promised :n: 4Jun 17, 2015 3:24 am downpipes arent actually supposed to be snug tight waterproof fittings at the bottom connection to the stormwater piping. the reason being, if theres a blockage or an already full soakpit, the water needs somewhere to go other than up into your roof!

Correct...unless it's a charged system draining uphill to a point of discharge or to a water tank's wet system of course. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: smaller stormwater pipes then promised :n: 6Jun 17, 2015 5:01 pm yeh but based on this users description, i highly doubt the 100 mm collars are an error of that magintude hahah! Re: smaller stormwater pipes then promised :n: 7Jun 17, 2015 11:48 pm Agree...plus the OP also mentioned a pit. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: smaller stormwater pipes then promised :n: 8Jun 19, 2015 8:15 am Sounds like you where supposed to be getting a flexible drainage system because your soil is reactive , in which case it should be fixed to comply with the engineers recommendation . With this system flexible joints are installed along the pipe work to allow for some movement to occur without pipe breakages . Also you where likely charged a fair amount extra for this to be installed , I was quoted $1700 from one builder , might also have to check the sewer now as well if one isn't right it's likely the other is not as well ( that should also be a flexible system if the soil is reactive ) . Re: smaller stormwater pipes then promised :n: 9Jun 19, 2015 12:26 pm Hey glenn, how do these flexible systems allow for blocked pipes/full soakwells? Re: smaller stormwater pipes then promised :n: 10Jun 19, 2015 2:57 pm http://www.stormplastics.com.au/index.html Flexible joints don't allow for blocked pipes or full soakwells. They are for the purpose of providing the ability of movement in the joints rather than a joint fail. This is ideal for highly reactive soils than can move. Can someone please offer some advice? Im DESPERATE. Because I'm completely and utterly exhausted. How long are variations taking with other companies at the moment? We… 0 18466 4 5105 As most others have posted above the install isn't compliant. The pipe is meant to be covered in loose soil or sand, the pipe has holes in it that leaks out a termicide… 10 5727 |
