Use of BIM in the Analysis of Concrete Damage Structures: A Systematic Review of the Literature
Marcela de Sana Barbosa

Wastewater treatment plants (WWTPs) are a type of critical civil infrastructure that play an integral role in maintaining the standard of living and protecting the environment. The sustainable operation of WWTPs requires maintaining the optimal performance of their critical assets (e.g., pumps) at minimum cost. Effective maintenance of critical assets in WWTPs is essential to ensure efficient and uninterrupted treatment services, while ineffective maintenance strategies can incur high costs and catastrophic incidents. Predictive maintenance (PdM) is an emerging facility maintenance technique that predicts the performance of critical equipment based on condition monitoring data and thus estimates when maintenance should be performed. PdM has been proven effective in optimising the maintenance of individual equipment, but its potential in predicting system-level maintenance

Implementation of a Robotic System for Overhead Drilling Operations: A Case Study of the Jaibot in the UAE
Xinghui Xu

The use of robots has typically improved workers’ health and safety and increased productivity and quality in manufacturing. Current advances in robotic and computer technology, combined with BIM, have led to new applications in construction. However, there is no general framework to guide the implementation of robots under current construction working schemes. Many questions and challenges need to be answered and overcome before robots can be economically and safely introduced to construction sites. Some questions include: 1) How does it affect the planning and workflow of related activities? 2) What are the implications regarding health & safety, and quality? 3) What is the best way to assess the viability of introducing robots onsite? 4) What are the organizational implications of using such systems? Still, there is plenty of work to do when considering common project

Automated Crane-lift Path Planning Using Modified Particle Swarm Optimization for High-rise Modular Integrated Construction
Aimin Zhu

Modular integrated construction (MiC) is a most advanced off-site technology. In a MiC project, it is critical but challenging to install prefabricated volumetric modules efficiently and safely, as they are much heavier and larger than conventional construction components and materials. However, the current crane-lift executions are heavily reliant on operators’ subjective judgement, which turns out to be time-consuming and error-prone, most notably when jobsites are congested. Automatic crane-lift path planning has been regarded as an important research topic for addressing this problem. Nevertheless, most previous studies did not consider the MiC-specific features of a crane lift such as correlation between module weight and crane trolley movement. Therefore, this paper aims to propose a modified particle swarm optimization (PSO) algorithm to automatically conduct crane-lift path planning

Spatio-temporal planning simulation of temporary elevators in construction using a game engine
Keyi Wu

Designing a reasonable and efficient transportation system of temporary elevators from the perspective of spatio-temporal planning is beneficial for the successful completion of construction projects. Specifically, the determination of the service period and floor of temporary elevators and the consideration of the limited availability of time and space should be taken seriously. The spatio-temporal planning of temporary elevators puts forward higher requirements for the display of planning solutions due to the complexity considering both time and space. However, current display ways are generally abstract, low-dimensional, and static, and even when the 4D model is adopted, the display effect of spatio-temporal planning solutions is still limited. This research presents a spatio-temporal planning simulation of temporary elevators in construction using a game engine to address those

A Web-Based GIS Tool for Progress Monitoring of Linear Construction Projects
Koshy Varghese

Efficient project monitoring is a key to a project’s success. Linear construction projects span across large distances and require similar activities to be carried out repeatedly over multiple small segments for project completion. Thus, monitoring their progress becomes challenging. This is a matter of concern since proper progress monitoring can aid in efficient utilization and distribution of project resources. Existing methods of monitoring are either time-consuming, expensive, or require significant human efforts. GIS has been used for monitoring linear projects, but the use has been limited. Therefore, this study aims to explore the potential of using GIS for collecting and visualizing data for enhanced progress monitoring of linear projects. For this purpose, this study proposes a process incorporating GIS and various open-source platforms in the form of a figure. The open-source platforms used
