The most famous of tilted building is Leaning of Pisa Tower where the eight-storey tower is 58.4m (192 ft) high, it weighs 14,500 metric tonnes and its masonry foundations are 19.6m (64ft) in diameter with a maximum depth of 5.5m (18ft) below ground level. The foundation slope towards the south at 5.5 degrees to the horizontal and as a consequence the seventh floor overhangs the first by 4.5m (14.76 ft). This dissertation adopts a mix research design of both literature review phase and quantitative approaches. The literature review phase consists of reviewing on tilted building and factors that will affect the tilted building. The survey and interview were conducted on how the tilted buildings were rectified by different types of construction methods such as underpinning method and soil extraction method. Contractors shall consider other methods and techniques which are not yet available in Singapore and Malaysia. The contents of the present study reveal that the following methods, which are known to be effective under certain circumstance has not yet been used in compatible situations in Singapore and Malaysia such as soil extraction, pali radice and jacking of grout method.
