Ties Spacing
(OP)
What is the spacing between ties at the start and end of the column as we used to say at the critical length of columns?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

2. Ties need to be placed to the maximum spacing required based on the applied shear and on the shear capacity of the concrete with the ties.
So these two items above control your tie spacing. Whichever is a smaller spacing controls.

Analyze your structure. Determine the shear diagram for your column in question.
Provide ties to resist this shear.
If your applied shear does not require ties then you must provide enough to be considered confinement reinforcing which is as you've described above 16*longitudinal bar diameter or 48*tie diameter or least dimension of your column.
If you can't choose you tie spacing after this then you likely shouldn't be working on this project

For columns with beams framing from 4 directions, per ACI 7.10.5.5, provide ties not more than 3 inches below lowest reinforcement in shallowest beam.
