Both descriptive and inferential techniques were used to
analyze the data. The results revealed that: speed in completion of projects and flexibility of the projects were the factors influencing the choice of traditional method of procurement while cost overrun and opportunity of sharing of risk between client and contractor were the risks associated with the method.
