【摘要】：与其他模式相比,DB模式在项目工期、费用及质量目标方面均具有优势,已成为国际工程承发包模式的主流趋势。国内,在工程建设领域,DB模式也得到积极推广,但截至目前,仍处于探索应用阶段,没有建立起系统成熟的管理体制,建设项目DB模式的风险管理亦存有不足。建设项目风险分为外部环境风险及内部环境风险。外部环境风险主要指社会风险及自然风险等客观风险,内部环境风险主要指项目主体行为风险。DB模式下,项目合同结构发生了较大变化。业主或其委托的设计单位完成方案设计及初步设计后,总承包商完成项目的施工图设计及工程施工任务,并对设计质量、工程工期、成本及质量承担全部责任,总承包商承担的风险大大增加。同建设项目的典型风险相比,影响项目目标的主体行为风险因素发生了较大变化,如总承包商的设计技术能力及设计进度管理能力对DB模式能否运用成功有重要影响。本文界定了DB模式的类别,从合同结构方面论述了DB模式的属性特征,并对DB模式与常用工程承发包模式进行了比较分析。在此基础上,进一步系统识别并剖析了DB模式的社会风险、自然风险及业主、总承包商、第三方监理等项目主体行为风险,通过归纳整理,建立了建设项目DB模式的风险评价指标体系。最后,文章比较了常用风险评价方法的特点及适用性,引入可拓评价方法创建了建设项目DB模式的风险评估模型,并以深圳地铁5号线项目为实证案例,分析验证了评估模型的可行性。通过本文的研究,能够帮助项目主体在项目前期决策时评估DB项目的风险,判断项目所处的风险状态,并有针对性的做出风险管控措施,这有利于促进DB模式在我国建设项目中的推广应用。
[Abstract]:Compared with other models, DB mode has advantages in terms of project construction period, cost and quality objective, and has become the main trend of international project contracting mode. At present, in the field of engineering construction, the DB model is also actively promoted, but at present, it is still in the exploration and application stage, and the management system of the system is not established, and the risk management of the DB model of the construction project is also insufficient. The risk of construction project is divided into the external environment risk and the internal environment Risk. The external environment risk mainly refers to the objective risks such as social risk and natural risk, and the internal environmental risk mainly refers to the behavior of the project main body Risk. In DB mode, the project contract structure is large Change. After completion of the design and preliminary design of the project design and preliminary design by the Owner or the design unit entrusted by it, the General Contractor shall complete the construction drawing design and construction tasks of the project, and shall assume full responsibility for the design quality, the project construction period, the cost and the quality, and the overall contractor's risk is greatly In comparison with the typical risk of the construction project, the main behavior risk factors that affect the project's target have changed greatly, such as the design technical ability of the general contractor and the ability of the design progress management to play an important role in the successful application of the DB mode The paper defines the category of DB mode, discusses the attribute of DB mode from the aspect of contract structure, and makes the DB model and the common project contracting mode. A comparative analysis is made. On the basis of this, further system identification and analysis of the social risk, natural risk and the risk of the main behavior of the project subject such as the owner, the general contractor and the third party supervision have been analyzed, and the risk evaluation of the DB model of the construction project is set up through the induction and arrangement. At last, the characteristics and applicability of the common risk evaluation method are compared. The risk assessment model of the DB model of the construction project was established by introducing the evaluation method, and the evaluation model was analyzed and verified with the case of Shenzhen Metro Line 5 project as an example. The study of this paper can help the project main body to evaluate the risk of the DB project in the early stage of the project, to judge the risk status at the project, and to make relevant risk control measures, which is beneficial to the promotion of DB mode in the construction of our country.
