In the fierce market competition process, the total construction contracting business out of necessity, be part of the professional engineering or service subcontract to a specific sub-contractors to complete, thus driving the construction division of labor tends to be more specialized and diversified. Through continuous development, project construction subcontractors in construction projects has become an indispensable part of the pile from the early works, foundation pit construction professionals, the main construction phase services to the sub, and the late fire, glass curtain walls and elevators projects, is gradually penetrate into the general contracting construction in all aspects. However, due to the corresponding sub-project management lags behind, has seriously affected the smooth progress of construction. How the construction project during construction, the right to carry out sub-project construction risk management, this is the project manager has to face a serious problem.In this paper, a commercial real estate project Y as the research object and go to the construction general contracting company which seriously sub-analysis of risk management in the construction of internal and external factors, in combination with previous studies, based on a commercial real estate for Y how to conduct engineering subcontractors in the construction phase risk management put forward their own views.The first is the characteristics for commercial projects, the use of expert investigation and inspections appearances combination of methods, to identify the total construction sub-contracting companies in the construction process of the risk factors. Then based on the analysis in the study, with reference to estimates and related risk factors, evaluation methods, decided to use a combination of qualitative and quantitative approaches, building construction general contracting business in the Y a commercial real estate construction sub-phase of the project estimates and evaluation of risk factors methods:Subjective scoring is the prerequisite for multi-level fuzzy comprehensive risk assessment method. After calculus proof, obtained the building construction sub-contracting companies in the value of the over all risk of the size of the period. Finally, in response to the level of risk, according to the overall project analysis and evaluation of results, the coping strategies, and to highlight handle the key risk factors handle the indices of the impact of project implementation. |
