| Construction cost index can reflect the changing levels of the construction cost, product price, and physical quantity index of different times. Its application in construction cost can provide valuable price foundation and decision support for every participants, provide basis for country in formulating relevant regulatory policies, and have significant meaning in improving management level of construction cost.In recent years, provinces and cities have begun to pay attention to compiling and releasing construction cost index, but a series of standards of price index have not been established domestically. The types and methods of compiling construction cost index vary according to regional standards, yet regional differences vary a lot, different places have different levels in compiling construction cost index, thus leading to imperfect cost index and unreasonable compiling methods. Therefore, it is imperative to establish a sound system of construction cost index and formulate detailed compiling standards and rules to normalize compiling work in all provinces and cities.Based on the practical principles of every phase in project constructions and the ripe experience of compiling construction cost index in UK and Hong Kong, this article establishes a system of construction cost index which meets the development needs of the real estate industry in our country. The emphasis is to combine the construction cost index with the valuation mode of quantities bill, and compile price index of quantities bill to serve the engineering bill of quantities. The compilation methods of various kinds of indexes can be confirmed by researching and analyzing index theories and index compilation methods, and the operability and applicability of the compilation methods can be verified by empirically studying the compilation methods.Construction projects feature long cycles and high costs, causing the prices of all factors of construction products in constant change in the system of market price and construction costs in fluctuation. Therefore, construction cost must be monitored in real time, and the industry pays more attention to the forecast of the construction price index. After analyzing and contrasting common forecasting methods, this article chooses grey forecasting model GM(1,1) according to the features of construction cost index, and concludes high forecast accuracy by empirical studies.In the end, the application of construction cost index in the entire project management stage has been analyzed, and its application in the construction dynamic management has also been analyzed by case study. |
