摘要
南水北调工程是一项宏伟的跨流域水调工程,对我国经济发展起到重要作用。在对该项目业主方、设计方、承包商方、监理方等进行工期影响因素问卷调查的基础上,首先利用SPSS对问卷信度进行检验,在确保问卷可靠性的前提下,运用因子分析法简化影响工期的影响因素,并对与项目相关因素、与业主相关因素以及与承包商相关因素进行重点研究。发现各方沟通与合同管理、合同方式与招投标、项目自身特点、业主要求、工程进度款、新技术与信息的利用等方面是最为重要的工期影响因素。这些结论为相关政府主管部门提供了决策依据,同时对其他大型复杂项目群的管理也提供了有益的参考。
China's South-to-North Water Diversion is a grand project, which plays an important part in the country's economic development. Data are collected from the questionnaire feedbacks from different participants (clients, designers, contractors, consultants) of the project and statistical analysis of 94 delay factors is conducted. The reliability of the questionnaires is examined and proven by means of SPSS. Principal components analysis is used in the factor analysis to simplify the variables into several dimensions, to determine the main factors and to perform further study on the project-related, client-related and contractor-related delay factors, respectively. The results indicate that the poor communication, client's unpractical requirement, delay payment to contractors, etc. are the important factors, that the use of new technology and information should be enhanced, and that many delay factors are correlative and precautionary measures should be taken to reduce the risks in construction delays. These conclusions have provided a decision-making foundation for related government departments, as well as a valuable reference to other complex project groups in their management.
