The construction sector in Egypt faces many challenges related to managerial issues. The construction industry considers a waste generator sector that harms the economy and environment. This study supposes that adopting lean construction approaches is essential in reducing waste and enhancing the Egyptian construction sector's performance. Data was collected from one hundred and sixty-two construction professionals who have the experience to design, manage, and construct projects and are involved in construction sites in the new capital city in Egypt. The overall conclusion of this study is compatible with the same studies worldwide, which are related to the adoption of lean tools in the construction sector affects time, cost, quality, safety, environment, and relationships positively, which is raising the value of resources and money. Results indicate that construction professionals apply lean tools in construction sites to manage, monitor, control, and construct projects, although they sometimes do not know what they are applying lean tools. Results show the knowledge level of lean concepts is less than the adoption level. Respondents evaluated 31 benefits of adopting lean construction. The major benefits are economic-related. The main Lean Construction “LC” tools adoption benefits are: Improve process control, Improved planning, Material storage control (access and inventory), and Time reduction.

埃及的建筑业面临许多与管理问题相关的挑战。建筑业认为废物产生部门会危害经济和环境。本研究假设采用精益施工方法对于减少浪费和提高埃及建筑部门的绩效至关重要。数据是从 162 名具有设计、管理和建设项目经验并参与埃及新首都建筑工地的建筑专业人士那里收集的。本研究的总体结论与世界范围内的相同研究一致，这些研究涉及在建筑行业采用精益工具对时间、成本、质量、安全、环境和关系产生积极影响，从而提高资源的价值和价值。钱。结果表明，建筑专业人士在建筑工地应用精益工具来管理、监控、控制和建设项目，尽管他们有时不知道他们正在应用什么精益工具。结果显示精益概念的知识水平低于采用水平。受访者评估了采用精益结构的 31 项好处。主要收益与经济相关。采用精益建设“LC”工具的主要好处是：改进过程控制、改进计划、材料存储控制（访问和库存）以及减少时间。结果显示精益概念的知识水平低于采用水平。受访者评估了采用精益结构的 31 项好处。主要收益与经济相关。采用精益建设“LC”工具的主要好处是：改进过程控制、改进计划、材料存储控制（访问和库存）以及减少时间。结果显示精益概念的知识水平低于采用水平。受访者评估了采用精益结构的 31 项好处。主要收益与经济相关。采用精益建设“LC”工具的主要好处是：改进过程控制、改进计划、材料存储控制（访问和库存）以及减少时间。
