Browse Forums Building A New House Re: Is there site cost for using pier and beam foundation? 2Dec 16, 2021 8:20 am Hey akgo Welcome to the forum Try getting a geotech/ soil report first Based on your soil classification and design then focus on the engineering, the cost for cut/fill pales into insignificance when compared to concrete Piling and Beams . Avoid the $ticker $hock that usually accompanies handing over a deposit to the builders for preparation of engineering. Once you have your own engineering data do a footings/slab comparison Here Slab and formwork Costs forewarned is forearmed Cheers Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Is there site cost for using pier and beam foundation? 4Dec 16, 2021 1:47 pm akgo Many thanks for your advice, StructuralBIMGuy. Is it better to do the geotech/ soil after the old house is knocked down or it doesn't matter? Thanks You're going to be paying site costs regardless of what foundation is designed for the site. The fact you're doing a knockdown/rebuild should already give you an idea that your site costs are going to be quite high. Probably higher than you even realise.

Re: Is there site cost for using pier and beam foundation? 5Dec 16, 2021 9:20 pm Thank you again for your reply, StructuralBIMGuy. Yes, I understand that I need to pay for the demolition. In general, is slab foundation cheaper than pier and beam foundation? Re: Is there site cost for using pier and beam foundation? 6Dec 17, 2021 8:18 am akgo In general, is slab foundation cheaper than pier and beam foundation? Having all the certified designs, engineering & information before you engage a salesman or builder is critical in making all the informed decisions. As those variations always incur huge costs and hardships to battlers and punters These are "Investments you'll be paying off for the rest of your life." nuf said Slab on well compacted, graded ground/ sand -> Class A is the cheapest Building on reactive clays is the dearest->Class M Its a bit more involved but your geotech/engineer will be able to enlighten you on the do's, don'ts and to some of the tricks That builders use to gouge extra costs on your build. OT, I visit sites before demo to assess potential hidden costs... never trust a home salesman's assessment. Too often I inspect sites butchered when the house has been demolished. You are then stuck with whatever site and engineering extras the builder throws at you? Too late then.... your pants have already been pulled down (humour) Steer well clear of fools that think we live in a land of plenty and that you should be paying whatever they want you to pay Cheers Chris Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Is there site cost for using pier and beam foundation? 7Dec 17, 2021 8:24 am Noname akgo Many thanks for your advice, StructuralBIMGuy.

Re: Is there site cost for using pier and beam foundation? 9Dec 20, 2021 5:07 pm akgo I would appreciate if someone can tell me if there is site cost for using pier and beam foundation, which doesn't require any cut and fill. Thanks Akgo There are a lot of variables like what is your site fall across your building area, site access for machinery, ground conditions ( rock, clay etc) , if you go for the pier and beam option what will the flooring be ie concrete or yellowtongue etc. It's a bit of a "how long is a piece of string" question. Typically for the sites with say a 2-3m fall in our area of sydney with mixture of clay and some rock, assuming a split level design, we are finding that cut and fill with a waffle slab is the most cost effective option.

Re: Is there site cost for using pier and beam foundation? 11Dec 20, 2021 8:31 pm akgo Thank you for giving me some idea about site cost, Simeon. Is it better to do the geotech/ soil after the old house is knocked down or it doesn't matter? Thanks no problem With the geotech it really depends on how many boreholes you want them to take and what sort of rig they use, and what your site access conditions are like. As an example, the guy I use has a drill fixed on the back of a 79 series ute. As far as I know, project home companies do a soil test with a hand auger. If I were you I would do the test after demolition and get 3 - 4 boreholes across the site cheers Simeon Architectural Homes & Duplexes - specialising in custom designing homes to your budget Get a Free Onsite Consultation Today or send a PM for information, questions or advice. Re: Is there site cost for using pier and beam foundation? 13Dec 20, 2021 8:58 pm Ashington Homes As far as I know, project home companies do a soil test with a hand auger. Simeon Dont know how it is in Sydney, but every test ive seen done down in Melbourne by volume builders has been done with a ute mounted auger. Client pays for this anyway. Can't imagine a hand auger would be a good cost/benefit proposition Dark matter scientist, can breathe underwater, mind reader and can freeze matter just by willing it. Trust me, its in my sig. Re: Is there site cost for using pier and beam foundation? 14Dec 23, 2021 2:47 pm Usually the first test is done with a hand auger if you are lucky you may be able to do one in the drive with a drilling rig but sometimes thats not possible. After demolition the soil testing company will return with a ute drill rig to do more test with at least one where the old house was.It is a good idea to do at least one hole do to 2.5m-3m as there may be neighbouring tree or on site trees that will require the slab design to have piers.
