For this problem dismantle the top of columns and remove the cement concrete from the steel bars on top of the columns for at least 6''. Then you place new bars in the area just cleaned making U AT COLUMN and weld these new bars made U with the old bars. Similarly weld the other bars and use cement concrete 1;1.5;3 in RCC work. It is a technical stuff so make sure you take the advise of a structure engineer at the site.
BUT I am in view that at the time when you construct the old building than you probably did not make the foundation strong enough to hold the weight for four story building. If that was the case then the old foundation may not be able to take the new load. Before starting work make sure that your old foundation is able to take the load of four story building.
For this please contact any structural engineer of your town or city, who after visiting the house will verify whether the foundation is fit for four story or not and also give solution at site for column.

Firstly S L Gupta sir I am grateful for ur kind reply, the building was designed for four story due to some problem we could complete, now not a problem. one of my friend structural engineer suggested me by drilling holes in the existing beams to required depth & inserting required rod into holes filled with some lockset, proceed with the work as per the designed plan. Sir I am not able to understand what he is telling about lockset material, sir what is ur opinion/suggestion.
thanks & regards
