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

在过去的二十年里，超过26,000名美国建筑工人在工作中死亡。这相当于每个工作日大约有五名建筑工人死亡。大约90%的工作场所伤害可追溯到不安全的工作做法和行为。这些数据表明，建筑安全仍然是一个大问题。经常发生的生命损失、受伤、侥幸和附带损害等令人悲伤的现实，构成了可以预防的责任。提出的创新是跟踪和监控移动资产的位置，包括工人和设备，以实时可视化的方式改善动态建筑工地的安全管理。考虑到世界上4-7万亿美元的建筑市场，这项技术存在巨大的潜力，如果成功，几乎任何需要或想要安全健康的建筑工作场所的业主、承包商或城市都可以使用它。该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害识别，并自动实时定位工人，包括在工人进入危险区域时发出警报。作为附加优势，所提出的技术可以1)提高效率，减少进行工作危害分析和管理的时间；2)提高工人？安全意识和对周围工作环境的了解；3)收集和存储安全知识数据，这将有助于公司内部安全知识的维持，并有助于知识从经验丰富的专业人员向新一代的传递。

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.
