Concrete Damage Repair -- Structural Integrity Restoration for Components in an older building

In my post Repair-Damage-To-Concrete-From-Freeze-Thaw-And-Deicing-Salts-Beam-In-An-Elevated-Garage-SimH1-105 we talked about damage to beam and the recommended repair.

The structure is reinforced concrete with massive brick in-fill walls. Some columns at the upper level have severe damage from concrete popping off because of swelling of corroded reinforcing bars resulting from moisture penetration. My investigation reveals that the columns support beams that carry a one-way slab, and support the vertical and lateral loading from infill brick wall.

It is an older structure -- and you always have the dilemma of how far you want to go with the repair. You can not restore and renew the structure to its original mint condition. And of course you come to the conclusion that as a minimum you do enough to restore the structural integrity for safety considerations.

I present here a drawing that shows the damage to the column at the base and a repair strategy to restore the structural integrity of the column for safety considerations.
