For that you will require the preliminary and final Engineering details translated to your unique design. There are footings on your original quote ie, A,S,M? you'll need to work out the extra costs involved upgrading Slab and formwork Costs On average say there is 40m3 of concrete in a house ( see eg above) The base material concrete costs say $200/m3 Therefore, 40 x 200 = $8K + reo + forms + labour +pump You need to ask the builder/engineer where's the extra $36K going? In a nutshell the building contract says pay up or pullout... unfortunately some Sales reps/builders don't give you that information up front as it spooks potential clients So now you will need to scrutinise the above data and costs and negotiate with the builder if he wants your business OT you would have been better off financially if you sorted this out before you handed over a deposit for the preparation of plans (PPA) Cheers Chris Very helpful.. thank you structuralBIMGuy. Re: $36K site costs for P class soil 17Apr 13, 2020 4:33 pm What is not considered by StructuralBIMGuy is the cost of cut and fill excavation, soil removal or new soil, compaction, etc. Reo, concrete, poly, concreters labor, pump won't cost a fortune, indeed. Also, concrete is way over $200/m3 if your are in NSW. Re: $36K site costs for P class soil 18Apr 13, 2020 8:27 pm Just ask for a breakdown of the costings, review it and ask if the builder can get another couple of subby quotes. If it is fair and reasonable then move on and get cracking. Registered Building - Always happy to help where I can and simply loves the game. DM me if you need help in VIC. I am not sure whether Perth has its own way of doing things in regards to this. Most of Perth has class A (sandy soil), except for some areas near rivers or hills. 2 12979 We were lucky in that our old house was so small (86 square metres) compared to the new house, they were able to take enough readings around the old backyard house before… 8 36896 PM me your email. I have a build excavation calculator you can use based on your plans to double check what your builder is telling you. Cheers Simeon 1 10169 |
