Finally, the paper discusses and compares the underlying reasons of the key factors from the client and contractor point of view. This paper will highlight the key factors that project team must pay closer attention to in order that their projects can be completed within budget and schedule, to acceptable level of quality, and to owners´ satisfaction.
