Alhough it would be nice to have sea level and reference levels info, elevation from project zero and height are sufficient information, for construction purposes, if you define correctly your project zero. Project altitude can take negative values. Project zero is a point on ground. Project Altitude defines the distance of project zero from sea level. In story settings the elevation values are from project zero. Your ground floor some times is a little elevated from ground some times up to 1.5m. You can put negative stories for basement and foundation. Use reference level 1=Ground floor level and reference level 2 for floor finish.
I am trying to make a schedule for the piles foundation. I've modelled the concrete piles with collumns, using the sea level to determine depth. I would like to show the top and bottom elevation to sea level/reference level, however I can only show this to project zero or home story that I am aware.

I respect your opinion, however in this part of the Netherlands we have piles foundations that go down 20 meters in the ground to find a layer of sand to build on. That is ussually some 20+ meters below sealevel. The project zero is determined to sea level as well and the contractor needs to know this for determining the length of the piles. The 'head' of the pile needs to be cut to reveal the steel reinforcement to make a foundation of concrete beams that supports the building.
This field of subcontractors works with sea level, so I need to schedule out sea level. It's best to not rely on their ability to do basic math
