建設項目DB模式的風險評價研究
發(fā)布時間：2019-01-17 13:36
【摘要】：與其他模式相比,DB模式在項目工期、費用及質量目標方面均具有優(yōu)勢,已成為國際工程承發(fā)包模式的主流趨勢。國內,在工程建設領域,DB模式也得到積極推廣,但截至目前,仍處于探索應用階段,沒有建立起系統(tǒng)成熟的管理體制,建設項目DB模式的風險管理亦存有不足。 建設項目風險分為外部環(huán)境風險及內部環(huán)境風險。外部環(huán)境風險主要指社會風險及自然風險等客觀風險,內部環(huán)境風險主要指項目主體行為風險。DB模式下,項目合同結構發(fā)生了較大變化。業(yè)主或其委托的設計單位完成方案設計及初步設計后,總承包商完成項目的施工圖設計及工程施工任務,并對設計質量、工程工期、成本及質量承擔全部責任,總承包商承擔的風險大大增加。同建設項目的典型風險相比,影響項目目標的主體行為風險因素發(fā)生了較大變化,如總承包商的設計技術能力及設計進度管理能力對DB模式能否運用成功有重要影響。 本文界定了DB模式的類別,從合同結構方面論述了DB模式的屬性特征,并對DB模式與常用工程承發(fā)包模式進行了比較分析。在此基礎上,進一步系統(tǒng)識別并剖析了DB模式的社會風險、自然風險及業(yè)主、總承包商、第三方監(jiān)理等項目主體行為風險,通過歸納整理,建立了建設項目DB模式的風險評價指標體系。最后,文章比較了常用風險評價方法的特點及適用性,引入可拓評價方法創(chuàng)建了建設項目DB模式的風險評估模型,并以深圳地鐵5號線項目為實證案例,分析驗證了評估模型的可行性。 通過本文的研究,能夠幫助項目主體在項目前期決策時評估DB項目的風險,判斷項目所處的風險狀態(tài),并有針對性的做出風險管控措施,這有利于促進DB模式在我國建設項目中的推廣應用。
[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.
