这项工作解决了所有建筑工地上出现的问题：施工活动之间的工作空间干扰的发生。从场地空间规划的角度来看，这一问题可能会不可避免地阻碍施工作业的进度。在真实的情况下，当空间干扰发生时，它们可能降低共享同一工作空间的工人的生产率，并且可能导致健康和安全危害问题。本文的目的是提出一种基于计算机的方法和开发的工具，以协助现场管理人员在工作空间冲突的分配和识别。作者重点阐述了建筑活动之间的“视觉空间竞争”概念。这个概念是基于在三维空间和时间的活动工作空间的动态行为的一个独特的表示。一个创新的基于计算机的工具，称为PECASO（模式执行和网站空间组织的关键分析）已经开发出来。4D（3D +时间）可视化的新兴技术已被选择产生一个有趣的4D空间规划和可视化工具。设计了一个多准则的工作空间故障严重度度量函数，嵌入了空间和进度相关准则。本文评估PECASO方法，以尽量减少工作空间的冗余，使用一个真实的案例研究。本文的结论是，PECASO方法减少了数量的竞争对手和占用的工作空间之间的冲突体积，这反过来又产生了更好的评估执行策略，为一个给定的项目进度。该系统被证明是一个有前途的工具，为4D空间规划，因为它引入了一种新的方式来沟通的工作方案。
This work addresses the problem arising on all construction sites: the occurrence of workspace interference between construction activities. From a site space planning context, this problem can lead to an inevitable roadblock to the progress of the scheduled construction operations. In real situations, when the spatial congestions occur, they could reduce productivity of workers sharing the same workspace and may cause health and safety hazard issues. The aim of this paper is on presenting a computer-based method and developed tool to assist site managers in the assignment and identification of workspace conflicts. The author focuses on the concept of ‘visualising space competition’ between the construction activities. The concept is based on a unique representation of the dynamic behaviour of activity workspace in 3D space and time. An innovative computer-based tool dubbed PECASO (Patterns Execution and Critical Analysis of Site-space Organisation) has been developed. The emerging technique of 4D (3D + time) visualisation has been chosen to yield an interesting 4D space planning and visualisation tool. A multi-criteria function for measuring the severity of the workspace congestions is designed, embedding the spatial and schedule related criteria. The paper evaluates the PECASO approach in order to minimise the workspace congestions, using a real case study. The paper concludes that the PECASO approach reduces the number of competing workspaces and the conflicting volumes between occupied workspace, which in turn produces better assessment to the execution strategy for a given project schedule. The system proves to be a promising tool for 4D space planning; in that it introduces a new way of communicating the programme of work.
