Cost Management Of The Design Process Based On BIM And LCC

Cost management is the most important management work. In the whole life cycle, according to the order of construction projects, people often will project into the appropriate stage. The first the investment decision is estimated in the project estimate, then the preliminary design and construction drawing budget are estimated in the design phase, finally final accounts of the project and maintenance management are estimated in the completion. As an owner who pay attention to cost management, because the order is make the project cost lower than the investment estimation, and ultimately achieve maximum benefit. however, the design stage is the key to control project cost, which is not only an impact on the cost of the stage, but also have a profound of the cost of the project life cycle, and have the 35%-75% of the impact of the project investment. Therefore, the design phase of cost management is particularly important. The design aspects have played a decisive role to the project cost, quality, and the completion of the feasibility stage to play good economic returns. Design phase of project cost management, it is need to combine technical and economic, make design based on sound economic basis, when determining the investment limits were optimized by design within the limits, to choose the most economical and reasonable way to achieve the goal.BIM as a new technology, which not only has an analog, visibility, coordination, optimization and can plot and other basic features, but also has a three-dimensional rendering, dynamic display, fast calculation volume, multi-operator contrast, virtual construction, collision detection and so on. These features of the BIM technology is to convenient for users, and to provide a strong technical support for scientific decision-making construction projects.The introduction of BIM technology in the design stage, not just to the design itself, but also enable the project cost management information throughout the life cycle to maintain visual, and The participating parties through the whole life cycle for sharing information to resolve issues relation to the traditional model of cost management.In order to research and exploration the cost management of design stage, first the thesis is analyzed to traditional cost management, the design phase in the LCC theory of cost management and BIM techniques, then as an example of an office building, the LCC theory and BIM technology combined with the actual engineering, and through the introduction of BIM technology, cost management of the design phase can be accurately visualized, in order to better carry out cost management in the design phase. In the whole life cycle can be simulated various stages, resulting in an optimal design scheme, and finally the construction design drawings can more easily be optimized.The basics of the paper is cost control by design phase Cost Management and LCC theory and engineering BIM technology combined. Model is rational designed, and scheme is feasible, providing some reference value for the implementation of similar projects.
