Browse Forums General Discussion 1 Aug 16, 2017 7:46 pm Hi All, Wanted to get some advice in regards to Rock Excavation and Removal as I really have no clue about this. First off, I had my Soil Test done a few months back and it did say there are some rocks on my lot. My sales consultant did not put any PS for rocks. They put a rock clause on our contract charging us $240 per cubic meter and $60 per m3 for removal. How big is 1 Cubic meter of rocks? Last week I meet up with my Site Supervisor onsite to show the rocks excavated and still being excavated (for plumbing). He then told me that prior to our meeting, the other 2 excavators already excavated rocks (I think they are the one who prepared the initial stage of lot). He did say they sent photos to show how much rocks was removed. I asked him to ask the guy how many cubic meters was removed already. So he called 1 of the excavators and asked how much rocks was removed and was told it was 3 truckloads, totalling to 27m3. I didnt care to ask anymore the other excavator because I was already disappointed on how much rocks was taken out prior to our meeting (If what the guy claim was true). To cut it short. My site supervisor told me there were 2 excavations done that both hit rocks prior to our meet up. and on the day of our meeting, the plumber was there and excavating rocks as well. 1st excavator claimed he got 27m3 2nd excavator - i dint care to ask and will just wait for the invoice 3rd excavator which is plumbing - My SS says just by looking, It is 10m3. My Lot is 640sqm. The house im building is 31 Squares Single storey. Is it possible to dig up that much rocks? How deep do they dig to get that much rocks? Sorry I have no Idea of how the excavation process is. Is it possible to say have 50 m3 of rocks on a 640sqm lot building a 31square house? I havent received my invoice yet. i just wanted to prepare myself in case they gave me a ridiculous amount to pay. I will post the picture soon, I just messaged my SS to send me all the photos of rocks that have been excavated. Thank You all for the Response, This will greatly be appreciated. I just wished that my Sales Consultant put a a few thousand dollars for PS for rocks. First time build. Re: Rock Excavation guide 4Aug 16, 2017 9:38 pm Btw, can you please give me some advice on what things should I ask the excavator when the invoice arrives? Just to give them idea that Im not clueless. Thats 3 truckloads for 1 excavation trades. 1 from plumbing roughly 10m3 they say and 1 more from another excavator which I didnt ask how much theyve taken Thanks mate Re: Rock Excavation guide 7Aug 17, 2017 10:55 am rockylot You haven't provided enough info to check that Do You Have the Contour survey, geotech report, and engineering details? Generally, if we can we put a sand pad down rather than excavate into rock? Sand is only $25m3.. just curious..was that considered first? BTW they should have discussed all the other options rather than select the most expensive one...Did they?

Hi - just educating myself re the cost of rock excavation Our report show rock (xw) at DCP40+ Our single story house and granny totals 24 squares. We will need drop edge beams as there is a slope. Is ther anyway to get a price range? Just trying to figure out what is a realistic provisional allowance for this. Have a feeling builder is low balling to get the tender signed.
