ABSTRACT
Purpose: This study aims to investigate technology-based health and safety (H&S) management to control the spread of disease on construction sites using a partial least squares structural equation modelling (PLS-SEM) approach. Design/methodology/approach: An extensive literature review is conducted to develop a conceptual framework. The variables identified from the literature review are included in a cross-sectional survey which gathered a total of 203 valid feedback. The variables for challenges are grouped under their relevant construct using exploratory factor analysis. Then, a hypothesized model is developed for PLS-SEM analysis using Smart PLS software. Later, the outcome of the model is further validated by nine construction experts using a semi-structured questionnaire survey. Findings: The results rationalized the relationships between the COVID-19 H&S measures, challenges in implementing COVID-19 H&S measures on construction sites and the innovative technologies in transforming construction H&S management during the COVID-19 pandemic. The possible challenges that obstruct the implementation of H&S measures are highlighted. The potential technologies which can significantly transform H&S management by reducing the impact of challenges are presented. Practical implications: The findings benefited the industry practitioners who are suffering disruption in construction operations due to the pneumonic plague. Originality/value: By developing a conceptual model, this study reveals the contribution of technology-based H&S management for construction projects during the COVID-19 pandemic, which remains under-studied, especially in the context of the developing world. © 2022, Emerald Publishing Limited.
ABSTRACT
A new wave of the Covid-19 pandemic struck Hong Kong in February 2022. It led to construction of a temporary 1000-bed hospital and 10 000-bed isolation and treatment facility on an island site in just 51 days using factory-made modules. To achieve such rapid construction, module assembly was carried out at a separate site between the factories and site. Several new modular construction technologies were also developed, including adjustable base supports, large-span roof modules, universal safety barriers and an intelligent cloud platform for construction management. But to enable sustainable construction of such emergency buildings in future, further studies on demolition, recycling and relocation of modular buildings need to be carried out in the post-pandemic era. © 2022 ICE Publishing: All rights reserved.
ABSTRACT
The construction sector is one of the largest industries that were impacted by the COVID-19 pandemic. While the COVID-19 outbreak had numerous negative impacts, the pandemic is perceived to have positive impacts on the construction industry such as an increased reliance on innovative construction technologies and methods. Despite the pronounced benefits of offsite construction and its potential to address many uncertainties and challenges experienced by the construction industry, little-to-no previous research has been performed to study the impacts of the COVID-19 pandemic on offsite construction. To this end, this paper used an integrated methodology to study how the COVID-19 crisis would unfold for offsite construction as well as to examine the offsite construction measures that were taken by companies during the pandemic. First, subcommittees of industry experts were formed to guide the research process. Second, interviews were conducted to get information related to the industry's perceptions on the current and future impacts of the COVID-19 pandemic on offsite construction. Third, data from business case studies were collected to verify the perceptions of the interviewed experts and the validity of the obtained findings from the interviews. The main findings of this paper showed that the COVID-19 pandemic has raised industry awareness on the importance of leveraging offsite construction technologies and methods in both short and long terms, since the pandemic required companies to seriously plan for further increasing their offsite construction capabilities. This research concluded that the enhanced focus on worker safety due to the pandemic will help accelerate the industry's move to offsite construction methods in the future. Ultimately, this research adds to the body of knowledge by showcasing why and how offsite construction technologies helped the industry adapt and respond to the challenging times during the COVID-19 pandemic and how the outbreak could be a catalyst for an increased reliance on offsite construction methods in the future. © 2022 American Society of Civil Engineers.
ABSTRACT
The spread of corona virus pneumonia in the world has brought serious threat to people’s life and health. The models of Beijing Xiaotangshan Hospital and Wuhan Huoshenshan Hospital prove that the construction of emergency infectious disease hospital plays an important role in dealing with sudden epidemic. However, because of the differences in construction technology, design concept and construction period, the cost management experience of traditional hospital can not be simply applied to the project cost of emergency infectious disease hospital. Taking Huoshenshan Hospital in Wuhan as an example, this paper analyzes the challenges and countermeasures of project cost in emergency infectious disease hospital, which can provide reference for similar project cost management. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
