虽然人们普遍认识到，由于返工的额外成本可能对项目绩效产生不利影响，但对影响因素的实证研究有限。本文的研究旨在确定不同的项目类型和采购方法对施工项目返工成本的影响。使用问卷调查，返工成本获得了161个澳大利亚建筑项目。分析和讨论了返工的直接和间接后果。结果表明，与预期相反，返工成本并不不同，相对于项目类型或采购方法。此外，还发现返工对项目成本增长的贡献率为52%，而成本增长差异的26%可归因于直接返工引起的变化。为了减少返工成本，从而提高项目绩效，它是假定施工组织开始考虑和衡量他们，以便了解他们的规模可以捕获，根本原因确定，并实施有效的预防策略。
While it is widely recognized that additional costs due to rework can have an adverse effect on project performance, limited empirical research has been done to investigate the influencing factors. The research presented in this paper aims to determine the influence of different project types and procurement methods on rework costs in construction projects. Using a questionnaire survey, rework costs were obtained from 161 Australian construction projects. The direct and indirect consequences of rework are analyzed and discussed. It is shown that, contrary to expectation, rework costs do not differ relative to project type or procurement method. In addition, it was found rework contributed to 52% of a project's cost growth and that 26% of the variance in cost growth was attributable to changes due to direct rework. To reduce rework costs and therefore improve project performance, it is posited that construction organizations begin to consider and measure them, so that an understanding of their magnitude can be captured, root causes identified, and effective prevention strategies implemented.
