建筑改造工程施工延期风险评价指标分析

Analysis of Reconstruction Project Delay Risk Evaluation Index

改造工程项目在现场作业中投资大,施工时间长,受自然因素的影响,因此在项目施工前期必须做好工程延期风险评价,从而确保工期的准确。采用文献研究法对改造工程项目研究现状进行分析,得出包含管理、安全、环境、质量4大因素的评价指标及11个不同类型的二级延期风险评价指标,采用层次分析法建立了改造工程延期风险评价模型。以A小区改造项目为例,对其进行风险评价。结果表明该项目在技术措施、安全措施风险及人员管理方面有着很大的风险,极可能在施工过程中影响工期,需对其进行针对性改进。

The reconstruction project has large investment and long construction time in the field operation.It is affected by natural factors.Therefore,it is necessary to evaluate the risk evaluation of project delay in the early stage of the project construction,so as to ensure the accuracy of the construction period.By using the literature research method,the study analyzes the research status of the reconstruction project;obtains the evaluation indexes including management,safety,environment and quality,and 11 different types of second-level risk evaluation indexes of the reconstruction project;and establishes risk evaluation model of reconstruction project delay with Analytic Hierarchy Process.Through taking the renovation project of A residential district as an example,the study conducts risk assessment.The results show that the project has great risks in technical measures,safety measures and personnel management,which may affect the construction period during the construction process.It is necessary to be improved.
