Process Monitoring with Support of IoT in Prefabricated Building Construction

Abstract

This paper focuses on how to use IoT technologies to monitor the project implementation process in prefabricated building (PB) construction, which will help optimize the construction schedule and ensure the quality and safety of PB construction. Although IoT monitoring can obtain a large amount of data during construction, the challenge is how to convert these data into intelligent information needed for feasible decision-making. Therefore, we need to clarify the key factors requiring monitoring during construction and how to use these data to make decisions. In this paper, we analyze the whole process of PB construction, comprising five phases: pre-construction, off-site manufacturing, delivery, on-site assembly, and finishing. Through mathematical model formulation to discover the key factors that affect the construction implementation process, we clarify the monitoring data that need to be obtained by IoT technologies. Using these monitoring data, it is possible to make judgments on process abnormalities, promptly give alarms, make proactive adjustments, and optimize the construction implementation process, thus achieving the goal of ensuring project quality and construction safety.

Deterrents to the IoT for smart buildings and infrastructure development: A partial least square modeling approach

“…These tests were performed as a component of the EFA on the pilot survey questionnaire. The KMO measure of sampling adequacy yielded a value of 0.726, signifying that the sample size and variables utilized in the analysis were sufficient for conducting the exploratory factor analysis [ 2 , 10 , 45 ]. A threshold of 0.6 or higher is deemed an acceptable value.…”

An Analysis on Promoting Prefabrication Implementation in Construction Industry towards Sustainability

“…Therefore, other than the fact that complex assembly works, typically done at the ground level/off-site, could decrease aerial works and further avoid accidents, fewer labor inputs in prefabricated construction could also reduce safety accidents onsite and contribute to sustainability development [125]. Emerging technologies, such as IoT and 3D visualization, have also been involved in the prefabricated construction process to achieve better safety control [126,127].…”

A Conceptual Framework for Collaborative Development of Intelligent Construction and Building Industrialization

“…Intelligent construction has a significant impact on the development of the construction industry. For example, building a multi-stakeholder management and control platform can integrate smart factories with the internet of things and locate prefabricated components intelligently through digital collaborative design (Kozlovska et al, 2021;Turner et al, 2021;Yuan et al, 2021). Construction robotics play an important role in human-robot coordination and selflearning, making construction more efficient (Yan and Zhang, 2021).…”
