Browse Forums Building A New House Re: Land is filled . what about the site cost 2Oct 06, 2011 11:16 am It depends on how deep the fill is. Usually the foundations need to go down to original good ground. It sounds like you need specialist advice before you buy The Harder You Try - the Luckier You Get !

Re: Land is filled . what about the site cost 4Oct 06, 2011 1:23 pm Specialist advice. You will need a soil engineer to give a soil compression report. As said, building on that land will create all sorts of problems unless the fill has been compacted. It can be expensive depending on how much fill has been put there and how long ago. An example is a marina up my way at Wallaroo. Lots of excavation and filling of land that took years to complete. The first blocks of land that were sold and built on all developed large cracks as the foundations and house settled. The ones getting built now (10 years on) are not as bad, but some still give some drama. Do your homework carefully before building. Re: Land is filled . what about the site cost 5Oct 06, 2011 1:32 pm Ask the developer for the engineering reports on your block, our builder was able to estimate site costs from this information and we actually fixed the site costs from this info Re: Land is filled . what about the site cost 7Oct 06, 2011 2:13 pm From experience, get lots of tests done with the soil report. We are in the final stages of a knockdown re build and something that was missed was a substantial amount of fill at the front corner of the old house. When it came time to do the foundations the concreter notice the difference in soil (one in clay the other looked like top soil) and it ended up costing us because there was too much fill (and it wasn't properly compacted) I would suggest (as above) that you get a report for the developer or owner of the land to see where the fill is (going to be) and if possible get to to not fill the block at all. That way if you place does need fill you can 100% get it right (if needed) and you will be able to control the compaction, depth, type of fill. Oh and as for the soil test sites, I think 300mm from boundary, 1200mm from boundary and 2000mm from boundary on both sides + at what ever the min set back is from the front of block then 1000mm in and 1000mm out from that point. Also similar for the rear of block depending on how long the house design you are looking at is. What would be really good is to choose a floorplan and then get soil tests at all corners of the design in relation to our block. Then you can concentrate the test sites on your design. That might seem a little extreme, but mine was a $15k surprise for that little extra fill that was missed. Had we found it we could have worked our levels around it and it might have only been $1k for soil removal 2 5502 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 37142 Thanks for the insight! My plot is a new development so hopefully I won't have too much problem during build as everyone should be roughly building together. I also… 2 3372 |
