Data were analyzed using Microsoft excel and ranked according to frequency index and severity index. The finding revealed that; delay in decision making, incomplete design and estimate at the time of tender, improvement of standard drawings/design changes during construction stage and errors and omission in drawings and in the bill of quantity were found to be the most severe factors. The study recommended that the prompt decisions are required during construction process in public organisations, design change should be controlled whileensuring prompt resolution in design change queries,effective coordination and communication between parties, ensuring prompt resolution in design change queries, effective and efficient material procurement system and a plan material delivery.
