deep excavation level need to be filled before doing the footing
deep excavation level need to be filled before doing the footing
(OP)
is it possible to backfill & compact a depth of 6-8m and then build the footing?
i have a problem in my project, the new received site, the site level have some area levels is lower than the excavation level by 6 to 8m.
is there any methodology supported by international codes ref. such ASTM describe this case.
Please support.

Is it practicable? Only the economics of your project can decide that.

can you support in such Ref.

There's no one code reference that will approve or deny the use of 6-8m of controlled fill.
That's a lot of fill though, are you sure that the current site level is 6-8m low? and if so, why does it need to come back up?
I'm envisioning major slope stability issues if your existing site elevations vary by that much.

the Engineer needs from us to:
Unauthorized Excavation: Consists of removal of materials beyond indicated subgrade elevations or dimensions without specific direction of the Engineer. Unauthorized excavation shall be at the Contractor’s expense.
1. Under footings, foundation bases, or retaining walls, fill unauthorized excavation by extending the indicated bottom elevation of the footing or base to the excavation bottom, without altering required top elevation.
actually we did not did unauthorized excavation, but this mistake happen when they firstly receive the site.

I've used rolling surcharge on dumped fills, sometimes combined with replacing the upper 5 feet or so with compacted fill under footing locations.
