Site cost - boreholes

hi all! I have here the appendex for my borehole logs results from the soil test conducted. we would just like to confirm what the measurements below mean? does the last 3 columns mean the depth of the borehole? do we need 3m borehole ? Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅

Means you have rocks at 1500-1600

Is that a bad thing? I have been provided fixed site costs for 16k to 20k but one builder is charging me 45k .. such a massive difference o.o and I am not entirely sure why there is such a huge discrepancy compared to other builders...

I think it is okay, you would most probably require piers to around 1200-1500 due to uncontrolled fill.
How did he explain the difference?

I do have a Meter fall on my land apparently.
But they didn't see that the developer already has placed a retaining wall.. so hopefully that can lower the cost quite a bit.one of the builders actually quoted be just 16k and was able to fix it. I mentioned this to them.
So hopefully they can look at the engineering again and lower the cost..
