The productivity and safety of construction projects are two major goals of the construction industry. Current project management approaches mainly depends on human site observations and manual data collection for detecting potential hazards and progress monitoring, respectively. Advancements in Artificial Intelligence (AI) and sensing technologies are providing new means for affordable, efficient and accurate automated data collection, which is expected to contribute to revolutionizing many industries. However, because of the complexity and the dynamic nature of construction projects, applying these advancements in the construction industry is more challenging. In order to take full advantage of these advancements, there is a need to have scientific understanding of the advantages and limitations of each technology, and then to develop innovative solutions to address the specific needs and challenges of the construction industry. This proposal aims to improve productivity and safety of construction projects using a cyber-physical system approach. The long-term objective of this research program is the knowledge creation related to improving productivity and safety of construction projects using the state-of-the-art AI techniques combined with Building Information Modeling (BIM), near real-time simulation and multi-agent systems, and ultimately realizing the concept of the Smart Construction Site. The proposed methodology has the following main tasks: (1) Updating the model of the site for progress monitoring using an Unmanned Aerial Vehicle (UAV) equipped with a Light Detection and Ranging (LiDAR) scanner; (2) Recognizing the activities of workers and equipment using an advanced computer vision method; (3) Developing real-time digital twin of the construction project based on a detailed 4D simulation model; and (4) Supporting decision-making on construction sites using a multi-agent system. The proposed research program is expected to have an impact on the construction industry by improving productivity and safety and reducing the effect of delays caused by unforeseen problems on construction sites. The resulting near real-time simulation calibrated by actual construction progress data will provide practitioners with accurate and reliable information about their projects, which will enhance risk management. It is expected that the results of this program and its HQP training will give the Canadian construction sector a competitive advantage based on technological innovations.

建筑项目的生产力和安全性是建筑业的两个主要目标。当前的项目管理方法主要取决于人类现场观察和手动数据收集，以分别检测潜在的危害和进度监测。人工智能（AI）和传感技术的进步正在为负担得起，高效和准确的自动数据收集提供新的手段，这有望有助于革新许多行业。但是，由于建筑项目的复杂性和动态性质，将这些进步应用于建筑行业更具挑战性。为了充分利用这些进步，需要科学地了解每种技术的优势和局限性，然后开发创新的解决方案来满足建筑行业的特定需求和挑战。 该建议旨在使用网络物理系统方法来提高建筑项目的生产率和安全性。该研究计划的长期目标是使用最先进的AI技术结合建筑信息建模（BIM），近实时模拟和多代理系统的知识创建与提高建筑项目的生产率和安全性相关的知识创建，并最终实现了智能施工网站的概念。所提出的方法具有以下主要任务：（1）使用配备有光检测和射程（LIDAR）扫描仪的无人机（UAV）进行进度监视的站点模型； （2）使用先进的计算机视觉方法识别工人和设备的活动； （3）基于详细的4D仿真模型开发建筑项目的实时数字双胞胎； （4）使用多代理系统在建筑工地上支持决策。 拟议的研究计划有望通过提高生产率和安全性，并减少因建筑工地上不可预见的问题而造成的延误的影响，从而对建筑业产生影响。实际施工进度数据校准的近实时仿真将为从业人员提供有关其项目的准确和可靠的信息，这将增强风险管理。预计该计划的结果及其HQP培训将为加拿大建筑业提供基于技术创新的竞争优势。
