Analysis on the critical factors of over-time and over-pay problems for government engineering project construction

针对目前困扰我国政府建设工程的超期与超支问题,设计表格并进行调研,找出关键因素。结果表明,影响工程进度的主要因素是业主拖欠工程款和暂时停工、承包商现金流不足与工程事故;而影响工程成本的主要因素是材料价格上涨、通货膨胀、业主临时扩大工程规模、承包商返工以及设计勘察资料不准等。应用吻合度分析方法,发现从环境、项目和设计方面相对可以进行进度和成本综合管理,但从监理、业主和材料方面则应该区别对待,这样才能提高政府工程项目建设的管理水平,增加效益。||A questionnaire has been designed and investigated to find critical influence factors on the over-time and over-pay problems for governmental engineering project construction. The results show that the main factors influencing over-time are payment delay and work suspension by clients, contractor’s financial difficulties and accidents during construction. The main factors influencing over-pay are increasing of material price, inflation, investment increasing by clients, contractor’s reworks during construction and improper soil investigation in design. Using agreement analysis method, it is found that a comprehensive management could be applied in aspects of environment, project and design. However, it should pay different attentions on management in aspects of supervision, client and material. The management of governmental engineering construction projects would be improved by a clearer understanding on the over-time and over-pay problems.
