摘要
减轻或避免无序施工可显著提高工程项目绩效水平。为确定工程项目无序施工关键影响因素,分析工程项目无序施工的影响机制,从团队、项目、技术及执行4个方面分析确定了工程项目无序施工影响因素,然后采用问卷调查、解释结构模型(ISM)等方法评估各影响因素的重要程度,分析影响因素系统中各因素间的相互影响逻辑关系。结果表明,项目团队经验水平不足、项目资金到位不及时、各方沟通协调不足是导致项目无序施工主观认知最重要的3个因素,各方沟通协调不足、业主干预频繁或有限、项目团队经验与水平不足、项目复杂难度大是具有较强驱动性的本质致因,施工效率低下、质量安全问题频发是具有较强依赖性的直接致因,必须加强对其进行控制,以预防无序施工的发生。
Mitigating or avoiding out-of-sequence work can significantly improve the level of project performance.In order to determine the key influencing factors of out-of-sequence work in engineering Projects,the influencing mechanism of out-of-sequence work in engineering Projects was analyzed,and the influencing factors of out-of-sequence work in engineering projects were analyzed and determined from four aspects that are team,project,technology and execution.Then,questionnaire survey,ISM and other methods were used to evaluate the importance of the factors affecting the out-of-sequence work of the project.The logical relationship between the influencing factors in the influencing factor system was analyzed.The results show that the lack of experience level of the project team,the untimely availability of project funds,and the lack of communication and coordination of all parties are the three most important factors leading to the subjective cognition of out-of-sequence work of the project.Insufficient communication and coordination between all parties,frequent or limited intervention by the owner,insufficient experience and level of the project team,and complex and difficult projects are the main reasons for strong driving nature.Low construction efficiency and frequent quality and safety problems are the direct causes of strong dependence.It must be controlled to prevent the occurrence of out-of-sequence work in engineering projects.
