Physical Distancing Analytics for Construction Planning Using 4D BIM 使用4D BIM进行建筑规划的物理距离分析
IF 6.9 2区 工程技术 Q1 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS Pub Date : 2022-07-01 DOI: 10.1061/(ASCE)CP.1943-5487.0001023

The COVID-19 pandemic has impacted how the construction industry operates around the world. To fight the risk of transmission, new health, safety, and environmental (HSE) protocols have been put in place. Among these protocols are social distancing and limiting the number of workers per area, where social distancing acts as a so-called protective bubble for each worker. Contractors are now required to attempt to achieve (and be prepared to keep) social distancing among their workers whenever needed and possible. Otherwise, they could be forced to halt operations due to having an unsafe environment. Accordingly, construction plans, and corresponding workspace assignments, should be revised in a four-dimensional (4D) environment to ensure fulfillment. Even after the end of this pandemic, the new HSE awareness achieved during this experiment is expected to reshape the so-called new normal of construction. Therefore, this paper presents a novel workspace simulation and management solution comprising a theoretical framework and a semiautomated tool to incorporate physical distancing during 4D planning. The semiautomated tool creates a 4D building information model, loaded with workspaces and social distance bubbles as stochastic variables, and utilizes Monte Carlo simulation to model uncertainties occurring onsite. The uncertainties considered are both temporal and spatial, i.e., changes in productivity and workspace sizes, respectively. This tool surpasses existing workspace management solutions in that (1) it has a schedule generation module to recompute schedule projections based on temporal uncertainties, (2) its workspace generation module can automatically create physical distance buffers around selected workspaces, as per site conditions, (3) its 4D simulation can realistically mimic the work progress on the site, and (4) its 4D clash detection module can smartly detect and report both soft and hard operational clashes. Additionally, the proposed analytics target three levels of clash resolution: site, workspace, and activity level. The framework and developed tool were tested against a residential building case study. Over the course of 155 days, 26 activities with 257 workspace assignments were examined. The proposed solution was able to capture the critical schedule duration (21 out of 155 days), the impactful 4D clashes (44 out of 2,900), and the activities involved in the most sever clashes (5 out of 26). Hence, the proposed method and the developed software tool will help planners/construction managers understand the space requirements for construction operations considering social distancing and other required safety buffering, identify critical spatiotemporal zones, and suggest resolution strategies for the resulting clashes based on the analytics. © 2022 American Society of Civil Engineers.
2019冠状病毒病大流行影响了全球建筑业的运作方式。为了对抗传播风险,新的健康、安全和环境(HSE)协议已经到位。这些协议包括社交距离和限制每个区域的工人数量,其中社交距离对每个工人起着所谓的保护泡沫的作用。现在,承包商被要求在必要和可能的情况下尝试在工人之间实现(并准备保持)社会距离。否则,他们可能会因为不安全的环境而被迫停止作业。因此,施工计划和相应的工作空间分配应该在四维(4D)环境中进行修改,以确保实现。即使在疫情结束后,在这次实验中获得的新的HSE意识也有望重塑所谓的建设新常态。因此,本文提出了一种新颖的工作空间模拟和管理解决方案,包括理论框架和半自动化工具,在4D规划中纳入物理距离。该半自动化工具创建了一个4D建筑信息模型,将工作空间和社交距离气泡加载为随机变量,并利用蒙特卡罗模拟来模拟现场发生的不确定性。所考虑的不确定性包括时间和空间,即分别是生产力和工作空间大小的变化。该工具超越了现有的工作空间管理解决方案,它有一个时间表生成模块,可以根据时间不确定性重新计算时间表预测,它的工作空间生成模块可以根据现场情况自动在选定的工作空间周围创建物理距离缓冲区,它的四维模拟可以真实地模拟现场的工作进度,它的四维冲突检测模块可以智能地检测和报告软、硬操作冲突。此外,建议的分析针对三个冲突解决级别:站点、工作空间和活动级别。框架和开发的工具在住宅建筑案例研究中进行了测试。在155天的过程中,审查了26项活动和257个工作空间分配。提出的解决方案能够捕获关键的计划持续时间(155天中的21天)、有影响的4D冲突(2,900天中的44天)以及涉及最严重冲突的活动(26天中的5天)。因此,所提出的方法和开发的软件工具将帮助规划者/施工管理人员了解考虑到社会距离和其他所需的安全缓冲的施工作业的空间要求,确定关键的时空区域,并根据分析结果提出解决冲突的策略。©2022美国土木工程师学会。
