Although the Singapore government has mandated submissions of building plans in building information modelling (BIM) format since July 2013, this does not yet seem to lead to enhanced productivity performance. BIM collaboration between designers and downstream contractors appears to remain inadequate. While many studies have been conducted on using BIM for better project outcomes, studies that relate BIM with the identification of non-value adding activities in the project lifecycle and the reduction of the resulting wastes are at infancy stage. This paper aims to propose a project management framework for enhancing the productivity of building projects in Singapore, which forms Phase I of an ongoing research project. A two-pronged approach is presented. Firstly, non-value adding activities in the current project delivery process that uses BIM partially in Singapore are identified by comparing the typical current process with full BIM-based processes; such activities are cut down after process transformation in terms of people, process, and technology. Secondly, time savings derived from reducing the wastes caused by these activities are quantified. The proposed framework was validated by a case study of a local residential project. It was concluded that this framework provides a valuable tool for project teams to enhance productivity performance.

使用建筑信息模型来提高生产力绩效的项目管理框架

尽管新加坡政府自2013年7月起已强制要求以建筑信息模型（BIM）格式提交建筑计划，但这似乎并未提高生产力。设计师与下游承包商之间的BIM合作似乎仍然不足。尽管已经进行了许多有关使用BIM改善项目成果的研究，但是将BIM与项目生命周期中非增值活动的识别以及减少产生的废物相关的研究仍处于起步阶段。本文旨在提出一个项目管理框架，以提高新加坡建筑项目的生产率，这是正在进行的研究项目的第一阶段。提出了两种方法。首先，通过将典型的当前流程与基于BIM的完整流程进行比较，确定当前在新加坡部分使用BIM的项目交付流程中的非增值活动；在人员，流程和技术方面进行流程转换后，此类活动将减少。其次，量化减少因这些活动造成的浪费而节省的时间。通过对一个本地住宅项目的案例研究验证了所提出的框架。结论是，该框架为项目团队提高生产力绩效提供了宝贵的工具。量化了减少因这些活动造成的浪费而节省的时间。通过对一个本地住宅项目的案例研究验证了所提出的框架。结论是，该框架为项目团队提高生产力绩效提供了宝贵的工具。量化了减少因这些活动造成的浪费而节省的时间。通过对一个本地住宅项目的案例研究验证了所提出的框架。结论是，该框架为项目团队提高生产力绩效提供了宝贵的工具。
