A Data Driven Use-Specific Site Asset Relocation Framework
In architecture, engineering, and construction (AEC) projects, site layout planning is often used to determine the initial locations of facilities and temporary structures. However, little attention is paid during the project to modify or optimize the site layout based upon the actual usage of these facilities. In reality, abandoned, broken, or unused facilities, as well as establishment and deployment of new facilities or temporary structures may require asset relocation and call for a revised site layout. In addition, certain patterns and frequencies in asset deployment and use may recommend relocation induced by safety or convenience concerns. Despite the potential benefits of asset relocation, at times the potential cost of such strategies outweighs its benefits. A key problem of interest to architects, construction engineers, and facility managers is effective relocation of facilities and temporary structures accounting for factors such as workers’ safety and convenience, as well as project economics. While there has been previous research in site layout planning, the potential value of facility relocation based on real-world data describing use, safety, and convenience has to the most extent remained unsolved. The application of asset relocation goes beyond AEC projects and can inform work in areas including transit systems planning, search and rescue operations, and crowd control. In this presentation, we propose a methodology that incorporates safety, convenience, and economic factors in a data-driven framework, and recommends the best possible relocation scheme given current project constraints. In particular, we first derive actual facility usage patterns based on users’ motion trajectory data, and determine the safety and convenience utility under current site layout. Next, we examine potential relocations that could optimize both utilities, and compute the cost of these relocations. Finally, we perform a benefit-cost analysis to identify the best possible relocation that guarantees safety, and improves convenience at a reasonable cost.
