Hi fellow builders!
After any advice/feedback/thoughts on my slab engineering specifications.
The site has been classed H1 and will require a cut/fill of around 450-500mm due to the downslope. The land is 10,000m2 so we avoid any zones of influence or having to do retaining walls etc...
Geotech report stated no fill material identified along with no rock being present. They determined the maximum estimated depth of 450mm concrete piers to be 1800mm.
Now my builders engineer has estimated piers to be at a depth of 1400mm but have placed a note stating the Geotech report has advised 1800mm pier depth to the entire slab.
Current provision is for 210 lineal metres (more than double the original estimate before engineering).
Would the piering depth usually be the same depth across both the cut and fill areas? I would of thought the cut side would require a lesser depth?
Should I get a 2nd Geotech report done to compare?
Any advice would be appreciated.
Thanks.
