Excessive deflections of slabs and beams were observed in an office building of a sugar factory in western Maharashtra. The problems was analysed and it was found that the beams and slabs were underdesigned. The paper presents a detailed scheme of repairs that was carried out by the authors. An office building of a sugar factory in western Maharshtra is about 30 years old. The building is a composite structure; outer walls are load bearing stone masonry and internal framing is of reinforced concrete (RC) beams, columns and slabs. Originally, central portion of size 23m X 6m was kept open providing double headroom for the ground floor, Fig 1. After about 10 years use, It was decided to cover this opening with slab. Entirely new set of foundations, columns, beams and slabs were cast in this opening, with a clear gap of about 5mm between the old and new structures.
