Hi There,
We recently settled in stage 6. Soil test revealed 15 Metres (More than 50 feet) of fill. Site costs are working out to upwards of 100K.
Have any other come across similar situation with soil test and site cost.

The building engineers are now sceptical of designing a foundation given the amount of fill. Significant cost overruns. Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 4Jul 06, 2016 4:48 pm Hi Randomone, sorry to hear that your site cost is over $100k. Which builder ? I am building with burbank and the site cost is fixed @$13k. Of course may be my land is flat. Shop around and ask other builders Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 5Jul 11, 2016 7:48 am randomone Hi There, We recently settled in stage 6.

Geotechnical report...What fill, Controlled or uncontrolled, bearing capacity,Bore holes, sampling, soil profile,type footings? etc,etc? $100k needs to be justified or is that just what the salesman is telling you?

Carlise Homes has recently informed us that they will not build for us giving the reason that the amount of fill is too deep. Anyone experience this problem? Any suggested solution? Will the house have any problem after building? Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 7Aug 26, 2016 7:56 am Hi Novice 000 Where in stage 6 are you? some parts are deep fill others are natural soil.The fill is very good (well compacted and clean) but very deep.AS JAMES GEOTECHNICAL has done a lot of compaction reports and testing in that estate so there should be plenty of information available to the engineers. Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 8Aug 29, 2016 10:58 am Hi Insider Unfortunately AS James did not conduct the test on our piece of land. The only did for our 2 neighbour land. They told us there is no point doing one specifically for us as the result will not vary much. Our lot is just next to the Mirvac Town houses. Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 10Aug 29, 2016 5:17 pm Yes Carlise did a soil test but they decided to base on the AS James report with the 15 meter fill. They said they will return us the full deposit and not charge us for the soil test that they did. Their soil test report - Horizon - Fill, Hole 1 (mm) 0-4500, Hole 2 - 0-2800, Hole 3 - 0-2800, Hole 4 - 0-4800 and hole 5 - 0-2800. Of course I do not understand what does the above results actually meant Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 11Aug 29, 2016 5:38 pm It means the found fill all the way down to 4.8m and did not encounter natural ground. The may have finished the test in fill because the cost of drilling to 15m would be significant and it would just confirm AS James report. The engineer in these situations usually has two choices (A) A rigid floating slab designed to withstand significant settlement ,if the fill is good enough or (B) Screw piles to natural 100k may mean the went with screw piles Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 12Aug 30, 2016 9:24 am Thank you for the explanation. Much appreciated. Very helpful indeed. Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 13Sep 02, 2016 9:47 pm StructuralBIMGuy randomone Hi There, We recently settled in stage 6.

Geotechnical report...What fill, Controlled or uncontrolled, bearing capacity,Bore holes, sampling, soil profile,type footings? etc,etc? $100k needs to be justified or is that just what the salesman is telling you? Hi StructuralBIMGuy, It appears that you are a professional who works in the building industry. So here I am, would like to ask you some Qs regarding a borehole at the front of my Lot. The Geotechnical Report from A.S. James for my Lot stating that an approx 12.0m thick fill was encountered... The fill was placed under controlled condition to a minimum 98% Australian Standard Compaction and supervised in accordance with the Leave 1 requirements as set out in AS3789 guidelines.... The site should be classified as Class 'P' in accordance with AS 2870-2011. However, considering the method adopted in placing and compacting the fill, th site can be re-classified as Class 'H2... I cannot find bearing capacity, sampling and type footing that you mentioned above from my report. Do you think the borehole might cost us a lot in term of site cost? The fellow poster Novice 000 said Carlise refused to build their home because of 7m fill that they've got. I am currently with Carlisle, do you think they might refuse to build for us as well due to the 12m fill? Any good suggestions? We went to colour appointment this morning with Carlisle. Our CLE told us that they did a solid test already, will let us know the result next Mon or Tue? Very nervous about result Wish carlisle still able to build our home, and site cost wouldn't be toooo expensive. Your response will be much appreciated! Cheers, Greenapple Re: Mirvac Harcrest Wantirna Stage 6 - Site Costs and Fill 15Sep 16, 2016 10:59 am Hi greenapple if it's a geo tech firm that builders use all the time then 1. Site reports are generally written the way builders want them to be written..some comprehensive ..some not? 2. IMO you are paying for it so you should be able to contact the report writer and ask for additional info 3.The footing details options will be designed by a structural engineer based on the site report..and the builders preferences please leave a pm Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Versaloc is a mortarless besser block system that still needs a properly engineered footing. If you just do a 400x200 footing it will fail in time. At 17m long you need it… 1 22680 1 16699 Henley should give you some indication of site costs. Too many variable to give you any reasonable accuracy 1 2389 |
