Ties question
Ties question
(OP)
If you have a concrete pedestal connecting to footing. Do you provide extra tie?
If yes, what is the reason behind this? I see footing details with and without this extra tie.

RE: Ties question
Ties are to control bursting of column sections from axial loads (think of the vertical column bars buckling outward).
Inside the footing there is adequate resistance to any (if any) outward buckling of the vertical bars.

RE: Ties question
Hokie is correct - the tie within the footing is used to help hold the vertical bars (or dowels) in position for the pier or column to be placed later. It's not required for structural purposes. If the contractor uses a more accurate template (ha!), it can be omitted.

By the way, if your pedestal is resisting any significant moment, the performance of the joint will be greatly improved if you turn the longitudinal bar hooks (the 90-degree hooks) such that they are pointing towards the centerline of the pedestal.
