Based On The Concept Of Integrated Comprehensive Construction Cost Risk Management Research

Led in 2015, China set up the Asian infrastructure investment bank (hereinafter referred to as "the bank"), key support infrastructure construction, as of April 15,2015, 57 countries have confirmed that became a member of the creation. At the same time, xi jinping, general secretary in 2013 "area along the" great idea, carry out and concrete implementation in 2015, "One Belt And One Road" great idea is China and along the silk road countries share China’s high quality production capacity, promote between countries discuss project investment, infrastructure, sharing cooperation. The rapid development of China in infrastructure construction, especially the construction industry, has brought the unprecedented development opportunity, opportunity has always been and challenges, great opportunities also poses a great challenge.The challenge for the construction project investment is very big, but the lack of liquidity; Long time construction process, the uncertainty factors, potential impact on the natural environment construction, environmental protection pressure. Construction engineering project implementation, in short, economic, technical, environmental risks are high.Under the environment of the construction of a conservation-oriented society, how to reasonable and effective use of construction funds, reduce all kinds of waste, to reduce the environmental pollution problem caused by the construction process, to effectively control construction cost of the project, the new do well the construction project cost risk management, project implementation with minimal resources and maximum social and economic value, is a very worth studying further.Stand in the Angle of the construction project, this paper introduces the concept of total cost management, under the guidance of integrated management thought of risk management as the breakthrough point, on a comprehensive engineering construction project cost risk factors in a comprehensive analysis, and gives comprehensive construction project engineering cost method of risk evaluation and risk coping strategies, building construction engineering projects of comprehensive project cost risk evaluation system and based on the integration concept, using the analytic hierarchy process (ahp) and fuzzy comprehensive evaluation method of comprehensive project cost risk evaluation model.On the use of research methods, chose to use fuzzy comprehensive evaluation method and analytic hierarchy process (ahp) integration, build a convenient and feasible, simple and easy to use based on the concept of integrated risk fuzzy comprehensive evaluation model, make up the fuzzy comprehensive evaluation method and analytic hierarchy process (ahp) a single method to evaluate risk factors to limit, better integration results have been achieved.In the evaluation and feedback on the results of comprehensive about construction project construction cost risk put forward the coping strategies, is helpful to guide construction project cost management work, in the process of project implementation for the project effective risk management provides a theoretical basis and scientific guidance, reduce the blindness of project risk management, to achieve project investment income maximization laid a foundation.In ziwei community shantytown renovation project, the application of the comprehensive construction cost risk evaluation system and the overall project cost risk evaluation model based on integration concept, analyses the project overall project cost risk, evaluation, and according to the results of the evaluation of targeted put forward the risk avoidance, control, transfer, dispersion, and retention risk coping strategies and the establishment of risk monitoring departments and persons responsible clear project risk management plan. These strategies and management scheme, which is beneficial to guide construction project cost management work in the process of project implementation, for the project risk effective management provides a theoretical basis and scientific guidance to reduce the blindness of project risk management, as the ultimate implementation projects to maximize investment returns laid a foundation.
