摘要设计错误会对项目绩效产生不利影响，并可能导致故障、事故和人员伤亡。尽管已经有大量研究探讨了设计错误的因果关系，但人们对设计错误成本却知之甚少。由于各种政府报告和建筑信息模型的出现，人们越来越重视使用非传统形式的采购方法，人们普遍认为设计错误成本将大大低于通过传统方式采购的项目。通过问卷调查，对 139 个项目的设计错误成本进行了估算。设计错误的平均直接和间接成本分别为合同价值的 6.85% 和 7.36%。研究发现，设计错误成本不会因采购方法和所使用的项目类型而显着变化。尽管这项研究为从业者对设计错误成本的看法提供了宝贵的见解，但他们的行为...
AbstractDesign errors can adversely influence project performance and can contribute to failures, accidents, and loss of life. Although there has been a considerable amount of research that has examined design error causation, little is known about design error costs. With increasing emphasis placed on the use of nontraditional forms of procurement methods as a result of various government reports and the advent of Building Information Modelling there is a general perception that design error costs will be significantly less than those projects procured by traditional means. By using a questionnaire survey, estimates for design error costs were obtained from 139 projects. The mean direct and indirect costs for design errors were revealed to be 6.85 and 7.36% of contract value, respectively. Design error costs were found not to significantly vary with procurement method and project type used. Although the research provides invaluable insights into practitioners’ perceptions of design errors costs, their ac...
