One of the most important reasons that may result in poor performance in Architectural, Engineering, and Construction (AEC) is to create a visualization of construction processes and poor exchanging of information between different work teams. Lean construction seeks to reduce and eliminate waste in the construction processes, while BIM seeks to improve collaboration between project team members.

This paper investigates BIM as a lean tool in the construction processes with a case study by concentrating on understanding the interactions between the design and implementation processes. The research demonstrates that BIM can detect errors, omissions, and clashes before construction, which helped reduce waste and make the construction processes more linear. BIM helped to minimize the design time to nearly 50% and supports prefabrication and installation activities to save up to one and a half months during execution by removing the waiting time wastes through construction processes. Alternatively, the BIM model can help reduce the number of change orders and RFI's; About 11% of increasing the total contract price and 25% of increasing the total contract time could be avoided by using BIM as a lean construction process tool.

可能导致建筑、工程和施工 (AEC) 表现不佳的最重要原因之一是创建施工过程的可视化以及不同工作团队之间的信息交流不畅。精益施工旨在减少和消除施工过程中的浪费，而 BIM 旨在改善项目团队成员之间的协作。

本文通过一个案例研究，通过关注设计和实施过程之间的相互作用来研究 BIM 作为施工过程中的精益工具。研究表明，BIM 可以在施工前检测错误、遗漏和冲突，这有助于减少浪费并使施工过程更加线性。BIM 有助于将设计时间缩短至近 50%，并支持预制和安装活动，通过消除施工过程中的等待时间浪费，在执行期间最多可节省一个半月的时间。或者，BIM 模型可以帮助减少变更单和 RFI 的数量；通过使用 BIM 作为精益施工过程工具，可以避免约 11% 的合同总价增加和 25% 的总合同时间增加。
