I-Corps: Building Information Model (BIM)-Driven Real-Time Mobile Asset Tracking System for Construction Safety

在过去的20年里，超过2.6万名美国建筑工人死于工作。这相当于每个工作日大约有5名建筑工人死亡。约90%的工伤可追溯到不安全的工作做法和行为。正如这些统计数据所表明的那样，建筑安全仍然是一个大问题。频繁的生命损失、受伤、险些相撞和附带损害的可悲现实构成了可以预防的责任。拟议的创新是跟踪和监控移动资产的位置，包括工人和设备，以改进动态建筑工地的安全管理，并实现实时可视化。鉴于全球价值4-7万亿美元的建筑市场，这项技术如果成功，将在全球范围内被几乎任何需要或希望安全健康的建筑工作场所的业主、承包商或城市使用。拟议的技术利用无线跟踪传感器和定位算法，在建筑信息模型(BIM)中实时显示移动资源。开发的系统将在项目施工阶段进行安全和健康危险识别，并实时自动定位工人，包括如果工人进入危险区域则发送警报。作为额外的优势，建议的技术可以1)提高进行工作危害分析和管理的效率并减少时间投入；2)改善工人？安全意识和对周围工作环境的了解；以及3)收集和存储安全知识数据，这将有助于维持公司内部的安全知识，并帮助将知识从经验丰富的专业人员转移到新一代。

In the past two decades more than 26,000 U.S. construction workers have died at work. That equates to approximately five construction worker deaths every working day. About 90% of workplace injuries can be traced to unsafe work practices and behaviors. As these statistics indicate, safety in construction remains a big problem. The sad reality of frequent loss of life, injuries, near-misses, and collateral damages poses liabilities that can be prevented. The proposed innovation is to track and monitor location of mobile assets including workers and equipment for improved safety management in dynamic construction job sites with real-time visualization. Given the world's $4-7 trillion dollar construction market, large potential exists for this technology, if successful, to be used worldwide by virtually any owner, contractor, or city that needs or wants safe and healthy construction workplaces.The proposed technology utilizes wireless tracking sensors and positioning algorithms to display mobile resources in Building Information Models (BIM) in real time. The developed system will undertake safety and health hazard identification at the construction stage of a project and automatically locate workers in real-time, including sending alerts if a worker enters a hazardous area. As the added advantages, the proposed technology can 1) enhance efficiency and reduce time commitment of conducting job hazard analysis and management; 2) improve worker?' safety awareness and their understanding of a surrounding working environment; and 3) collect and store safety knowledge data which will assist to sustain the safety knowledge within the company and help knowledge transfer from experienced professionals to new generations.
