Based on the theory of project cost management, the deeper level of Scarlett to Dongshan County 3# building project cost control of each stage of the study, which will be of value engineering idea is applied to determine the design scheme, the AHP method scientifically and reasonably applied to the bidding process, earned value method combined with quantitative analysis in construction stage. The qualitative research is the foundation, the quantitative analysis is the support, the combination of the two is more convincing. The results show that the expansion of system management based on system and method proposed in this paper, the effective control of the cost, not only to make the project cost control in the expected and save money, improve enterprise profitability and development capacity. |
