在过去几十年里，翻新项目的生产力不断下降。与此同时，世界各地的翻新活动正在迅速增加，以实现更可持续的建筑环境。因此，了解低生产率的原因是实现环境和经济可持续性的一个关键方面。本研究的目的是确定翻新项目中的“凑合”及其背后的原因。采用案例研究的方法收集数据，积极参加每周的“最后计划者系统”会议，现场观察三个项目的工作进展情况，并对六个行业进行工作抽样研究。研究表明，在这三种情况下，“凑合”很可能是最普遍和最主要的废物形式，而生产管理不足是主要原因。这是通过首先确定从文献中的决策的已知影响和在案件中观察到的最常见的负面影响之间的重叠。第二，发现说话通常包含最大的减少潜力，这种潜力与“凑合”有明显的相关性。这项研究是了解装修项目中的“凑合”，以及如何检测和减少装修中的铅废物，并提高建筑生产力的重要一步。
Refurbishment projects have shown declining productivity in the last decades. At the same time, refurbishment activity is increasing rapidly worldwide to achieve a more sustainable built environment. Thus, understanding reasons for the low productivity is a key aspect to reach environmental as well as economical sustainability. The aim of this research has been to identify Making-Do in refurbishment projects and the reasons behind it. A case study research approach has been used to collect data by actively participating in weekly Last Planner System meetings, observing work in progress on-site on three projects and conducting work sampling studies on six trades. The research showed that Making-Do is highly likely to be both the prevailing and lead waste form in all of the three cases, and that insufficient management of production was the main cause. This was found by firstly identifying an overlap between known impacts of Making-Do from literature and the most occurring negative impacts observed in the cases. Secondly, finding that talking generally contained the biggest potential for being reduced and that this potential had an apparent correlation with Making-Do. This research is an important step towards understanding Making-Do in refurbishment projects and how to detect and reduce lead waste in refurbishment, and to improve construction productivity.
