Elevator sump basin

Elevator sump basin

Elevator sump basin

(OP)
I'm working on a project with a few elevator sump basins that are much lower than adjacent foundation work. In lieu of dropping the adjacent footings below the basin does anyone have experience with having the basin be designed for foundation pressures?

RE: Elevator sump basin

The basin is not designed for foundation pressures unless there is hydrostatic uplift. In that case, design accordingly, but not a big issue.

RE: Elevator sump basin

I have always seen the foundations near the elevator lower than the pit. I have never seen the pit designed for foundation surcharge. However, the pit walls can load bearing.

In my part of the world, the terminology is a little different. The elevator pit is the big thing with equipment in it. And, elevator pits usually have a sump for a waste (storm?) water pump.

RE: Elevator sump basin

(OP)
I should've been a little clearer. This is a sump basin for an elevator, but isn't located very close to the elevator pit. It's essentially a big tube stuck in the ground with piping that runs from the elevator pit to this basin, as I understand it. It's constructed of any number of materials.

I was questioning whether I could specify that the basin be designed for foundation pressures. Sounds like that's not the best road to travel.
