Options: 1. Columns can be strengthened with steel plates 2. If floor live load was designed for 100 psf (which is becoming more common) - An option would be to back the live load off to 50 psf + 20 psf partition load. (and don't forget to take full advantage of live load reductions) 3. Can the floor for the remaining levels be changed to a thinner concrete slab - If a two hour floor was used, by fireproofing the deck one to two inches of concrete can be removed. 4. Watch out for your lateral system - it will most likely need to be strengthened also. 5. Option - add additional columns. If a steel beam system was used above, columns can easily be introduced. (This will help the foundation design as well) If your floor is a joist/joist girder system this can still be done, however reinforcing the girders can get messy. 6. Foundation - Spread footings or mat foundations can be added on to. (Epoxy rebar to existing foundations, but watch your flexural steel in the foundations - this could get tricky) Caissons could be more difficult- I would suggest drilling new caissons and building grade beams under the existing columns to transfer the load to two caissons in lieu of the one in place. Hope this helps Richard Dahlmann P.E.
