Study On Supervision-Based Construction Project Investment Control

Great progress has been made for project investment control that persists throughout the whole process of engineering construction project, including decision-making, design, bidding, construction, and completion and acceptance, yet still problems abound. First, investment control in supervision is limited to the construction stage, ignoring that it's also important in the design stage. Second, great emphasis has been placed on quality control, but the mutually reinforcing and restricting relationship among the three-controls -- investment, quality and progress - has not been fully recognized and the integrated management not really implemented. Last but not least, the crude settlement auditing method in the completion stage does not have an effective link with the previous stages. Against such background, this paper investigates the investment control in supervision, with design, construction and completion stages as the focal points.First, analysis is done on the current situation of investment control in supervision, pointing out defects that have thwarted the effects of investment control. Through studying and analyzing the development and characteristics of investment control in developed countries and regions, this paper proposes that systematic investment control should be maintained and strengthened from design stage through construction stage to completion stage.Two threads are adopted to enunciate how inspectors should conduct investment control: the integrated management of the investments throughout the design, construction and completion stages and the integrated management of the investment, quality and progress within design and construction stages.In the end, positive analysis is done on the Haining Stadium project by linking theory with practice. Based on the needs of the construction party, supervisors step in during the design stage and exercise efficient control over investment, quality and progress according to prior-control and dynamic control principles. During the construction stage, investment is effectively controlled through earned value concept and measurement-payment, as demonstrated in the construction and installation engineering. During the completion stage, the settlement auditing report is quickly and accurately formulated based on follow-up audit from the construction stage, and change orders, claim notes and minutes.Therefore by providing reference for the investment control in supervision, this paper shall have practical significance.
