Re: Calculating slab height using RLs 14Jan 23, 2014 7:53 am Sometimes there are tiny cross-section "mini plans" indicating the degree of slope and the slab height etc information. On my plan, there are 4 of these for indication of cross-section slopes for driveway. And in the first draft of construction plan, there are much more. Not sure if it is due to the complex and steep slope that I have. Re: Calculating slab height using RLs 15Jan 23, 2014 7:57 am Liliana The Nullarbor???? hahaha The ARI (intensity) doesn't relate to annual rainfall. I'm guessing 1:100 as per AS/NZS3500.3:2003 5.2.3 (surface drainage systems) The intensity figure will be interesting. The plumbing and building codes are not always harmonious. 3in1 Supadiverta.

Re: Calculating slab height using RLs 16Jan 23, 2014 8:11 am snowing Sometimes there are tiny cross-section "mini plans" indicating the degree of slope and the slab height etc information. Do you mean something like this from our engineering plans? I've had a look at your thread and your house plans Snowing. (Very nice, by the way.) You have a FFL (finished floor level) inside the house and not an RL. Are they different? Re: Calculating slab height using RLs 17Jan 23, 2014 10:27 am Hi Liliana The whole point of hiring a building designer is to come up with plan and documentation that will satisfy not only owner's requirements but also all legal constraints overcome all natural site limitations and adversities and make it all fit. That is a recipe for construction. Builder is the cook and he has to follow a recipe and there is no excuse (that is what he promised to do in the warranties). If there is a problem with design levels then fine, that should be brought up in writing with the owner and the designer with a request for direction and or variation to the contract. Then review takes place and decision is given, and probably variation approved. It is just not good enough to say levels are not right and builder doing it his own way. You will end up with a dish you don't like.

I agree we pay licensed 'professionals/experts' whatever you want to call them and really they can turn out to be complete duds. With so much regulation in Australia how the heck does this happen? That is exactly what happened with ours, the builder blamed the drafty and me for hurrying him into council (it took months) and then did exactly what he wanted with no regard to what was approved. As you say Building Expert there is always the chance and time for variations before the ground is cut. In our case there was a few months where the plans and engineering could have been amended in council with a section 96 - so absolutely no excuse. So anyone who has not yet had the ground cut/slab laid, please look at your levels and understand what they mean. Ask questions and get expert advice if you doubt what they are telling you or if you think the slab will be too high or too low. Obviously not all builders (if you can call them that) understand what they are doing or don't care. Re: Calculating slab height using RLs 19Jan 23, 2014 11:12 am Hi Lenny171,
Our house is built and finished. It is because of ongoing problems with pipes and paving that I am revisiting this issue. The first time we knew there was a problem was at the first site meeting. The ground had already been cut and the crew were on site to do the concreting but couldn't proceed while the builder and building designer had an argument. We never got to the bottom of the issue because we had varying explanations from both the builder and building designer and felt under pressure to resolve the situation by taking our house off boundary. At no stage were we approached by either of them prior to this to say that there was an issue and what the issue was. Subsequently the builder claimed the site levels were wrong but, in writing, would only state that the plans, as drawn up, would have taken us over the 3.6m boundary limit. The building designer, when pressed at the time, stated that she had instructed the builder to lower the whole house and raise the slab in the garage if he wanted to but that he had ignored that and he had just dropped the garage floor a bit thinking the roof would follow. Whichever explanation you believe, it seems slab heights are not fixed by plans and they are a moveable feast! And you can get building permits for houses that can't be built! PS And taking the house off boundary doesn't seem to have resolved all the issues anyway if the problems with our slab height are anything to go by.
