Abstract

Purpose

This paper aims to explore augmented reality (AR) applications in construction safety academic literature and propose possible improvements for future scholarly works. The paper explicitly focuses on AR integration with Construction 4.0 technologies as an effective solution to safety concerns in the construction industry.

Design/methodology/approach

This study applied a systematic review approach. In total, 387 potentially relevant articles from databases were identified. Once filtering criteria were applied, 29 eligible papers where selected. The inclusion criteria were being directly associated with construction safety focused on an AR application and AR interactions associated with the Construction 4.0 technologies.

Findings

This study investigated the structure of AR applications in construction safety. To this end, the authors studied the safety purposes of AR applications in construction safety: pre-event (intelligent operation, training, safety inspection and hazard alerting), during-event (pinpointing hazard) and post-event (safety estimation) applications. Then, the integration of AR with Construction 4.0 technologies was elaborated. The systematic review also revealed that the AR integration has contributed to developing several technical aspects of AR technology: display, tracking and human–computer interaction. The study results indicate that AR integration with construction is effective in mitigating safety concerns; however, further research studies are required to support this statement.

Originality/value

This study contributes to exploring applications and integrations of AR into construction safety in order to facilitate the leverage of this technology. This review can help encourage practitioners and researchers to conduct further academic investigations into AR application in construction safety.

Abstract

Purpose

Despite extensive academic research related to digital technologies (DT), their integration into architecture, engineering and construction (AEC) projects lags in practice. This paper aims to discover DT deployment patterns and emerging trends in real-life AEC projects.

Design/methodology/approach

A case study methodology was adopted, including individual case analyses and comparative multiple-case analyses.

Findings

The results revealed the temporal distribution of DT in practical AEC projects, specific DT products/software, major project types integrated with digital solutions, DT application areas and project stages and associated project performance. Three distinct patterns in DT adoption have been observed, reflecting the evolution of DT applications, the progression from single to multiple DT integration and alignment with emerging industry requirements. The DT adoption behavior in the studied cases has been examined using the technology-organization-environment-human (TOE + H) framework. Further, eight emerging trend streams for future DT adoption were identified, with “leveraging the diverse features of certain mature DT” being a shared recognition of all studied companies.

Practical implications

This research offers actionable insights for AEC companies, facilitating the development of customized DT implementation roadmaps aligned with organizational needs. Policymakers, industry associations and DT suppliers may leverage these findings for informed decision-making, collaborative educational initiatives and product/service customization.

Originality/value

This research provides empirical evidence of applicable products/software, application areas and project performance. The examination of the TOE + H framework offers a holistic understanding of the collective influences on DT adoption. The identification of emerging trends addresses the evolving demands of the AEC industry in the digital era.

Abstract

Purpose

In the construction sector, site excavation is one of the most dangerous and challenging activities. Proper training can be an effective way to mitigate excavation hazards. Virtual reality (VR) has been used as an effective training tool to enhance safety performance in various industries. However, little attention has been paid to the potential of this technology for construction excavation safety training.

Design/methodology/approach

This study proposes an immersive VR training system for excavation safety and hazard identification. The proposed VR training system was compared with a health and safety manual via a controlled experiment.

Findings

Results based on scores obtained immediately after training indicate that VR training significantly enhanced practical performance, knowledge acquisition and self-efficacy. Results also show that knowledge was retained four weeks after training. In addition, VR training outperformed health and safety manuals regarding knowledge retention.

Originality/value

This study measures the practical performance to evaluate the effectiveness of the proposed VR training system. Also, this study compares the VR training system with a traditional training method by measuring knowledge acquisition and retention. The results demonstrate the potential of VR as a training tool for excavation safety and hazards.

Abstract

Purpose

With growing concern about sustainable development and increased awareness of environmental issues, digital technologies (DTs) are gaining prominence and becoming a promising trend to improve productivity, sustainability and project performance in the construction industry. Nonetheless, the uptake of DTs in the construction industry has been limited and plagued with roadblocks. This study aims to identify critical barriers for construction organisations to adopt DTs and to demonstrate relationships between organisational characteristics and the perceived DTs adoption barriers.

Design/methodology/approach

This study adopted an explanatory sequential design by combining the advantages of quantitative and qualitative data. Data collection methods include literature review, a pilot study, questionnaire survey, and semi-structured interviews. Questionnaire data were analysed by using SPSS and multivariate regression technique. The interview data were processed by using content analysis to validate and supplement findings from the questionnaire.

Findings

Based on the survey and interview results, eight critical barriers were identified: the three top critical barriers are (1) “status quo industry standards”, (2) “lack of client interest” and (3) “lack of financial need/drive for using DTs”. The eight critical barriers were further classified into technical, environmental, and social dimensions to determine the major constructs that hinder DTs adoption. A theoretical framework articulating critical barriers with underlying components and root causes was also proposed. Furthermore, by using multivariate regression analysis, a model was developed to link the organisational characteristics with barriers to DTs adoption.

Practical implications

By referring to the framework and the model developed, academics, industry practitioners, and decision makers can identify pivotal areas for improvement, make informed decisions and implement remedial measures to remove the barriers to digitalisation transformation.

Originality/value

This study contributes to the literature on construction innovations by investigating barriers to DTs adoption holistically as well as perceptions of the impact of organisational attributes on these barriers. It establishes the groundwork for future empirical research into the strategic consolidation of movement of DTs adoption and diffusion.

Abstract

Purpose

The aim of this paper is to review and analyze the research literature on the health and safety issues of migrant workers in the construction industry from 2000 to 2022.

Design/methodology/approach

5 steps method is used to conduct a systematic review to achieve the objectives. After scanning two authoritative search engines “Web of Science” and “Scope”, 60 articles are selected from 225 publications for identification and review. These identified articles are classified by research fields, countries and time span.

Findings

The review finds that with the increasing influence of migrant construction workers, the number of publications on the health and safety of migrant workers has shown a rapid upward trend. Moreover, language barriers are the most dominant safety risk factors encountered by on-site migrant workers. This systematic literature review also summarizes the definition of migrant workers and solutions to reduce safety risk factors.

Originality/value

The research data on the health and safety issues and risk factors of migrant workers in the construction industry is still limited. This literature review summarizes the research trends and contributions of the literature in this field in the past 22 years and provides theoretical support for future research on the safety management of the migration construction field.

Abstract

Purpose

The purpose of this paper is to elicit the expectations for resilient post-disaster rebuilds from Caribbean project end-users. In anticipation of future climatological, meteorological, hydrological or geophysical disasters disaster, key stakeholders can articulate and incorporate strategies for resilience development, thus leading to improved end-users’ satisfaction and confidence.

Design/methodology/approach

This paper engages the results of a systematic literature review that identified 24 empirical resilience factors for post-disaster reconstruction projects. These factors informed a semi-structured questionnaire to elicit the perspectives of Caribbean end-users on a seven-point Likert scale. The quantitative analysis of both factor ranking and principal component analysis was performed to identify correlations and provides further interpretations on the desires of the end-users for resilient rebuilds.

Findings

The results presented in this paper highlight the collective perspectives on the Caribbean end-users on what they perceived to be aiding more resilient reconstruction projects. They identified reconstruction designs mindful of future hazards, policies that aid climate change mitigation, active assessment of key structures, readily available funding sources and ensuring stakeholder’s unbiased interest as the top-most empirical factors. Factor analysis suggested collaborations with inclusive training and multi-stakeholder engagement, critical infrastructure indexing and effective governance as the critical resilience development factors.

Originality/value

To the best of the authors’ knowledge, this paper is first of its kind to explore the perspective of the Caribbean people regarding disaster reconstruction projects. It addresses developmental avenues for measurement indicators towards resilience monitoring and improvement. Additionally, the perspectives can provide construction industry professionals with tools for improved operational resilience objective-setting guidance, for Caribbean construction.

Abstract

Purpose

This paper aims to investigate the emergence of new success measures for buildings and infrastructure post-disaster reconstruction projects, beyond the traditional ”iron triangle”, which have gained prominence with the increased involvement of clients and end-users in these projects. Consequently, the industry is obliged to reconsider the critical factors regarding what constitutes a successful outcome from the perspectives of these stakeholders.

Design/methodology/approach

Data was gathered from end-users in four Caribbean islands using a questionnaire survey on eight empirical success indicators obtained from an extensive systematic literature review. To elicit a ranking and correlations amongst the end-user’ perspectives on the indicators, factor analysis and structural equation modelling techniques (SEM) were conducted.

Findings

The factor analysis found “safety” to be the most important empirical success measure, while “change” ranked the least important. Correlation analysis using SEM identified two new composite indicators, namely, “competence” with delivering timely and quality environmentally friendly and sustainable projects and “adaptability” in ensuring project objectives reflect beneficiaries’ expectations amidst internal and external influences, to be critical of end-users’ measurement indicators that describe their assessment mechanism. Measurement and structural models validated “safety” and “satisfaction” to be the highest loading variables in the two composites, respectively.

Research limitations/implications

The research focussed on findings in English language articles; therefore, any claim to a complete list of indicators from the literature can be amiss.

Practical implications

Results confirm the traditional “iron triangle” of time, cost and quality to be limited in assessing reconstruction project outcomes and the views and expectations of the potential beneficiaries need to be factored in the planning, design, execution and post-handover stages in all reconstruction projects.

Originality/value

This paper was very specific in its attempt to investigate new success indicators for reconstruction project outcomes, aiming to assist with developing comprehensive project objectives that resonate with all stakeholder groups.

Abstract

Purpose

The purpose of this study is to elicit the success factors from empirical evidence, as construction industry requires an improved understanding of factors for managing projects to positive outcomes. Increased stakeholder involvement, including the new technologies, achieving sustainability and safeguarding health and safety, whilst at the same time facing uncertainties, it is crucial to examine whether there are new factors that drive construction projects to succeed, especially from a value-driven perspective.

Design/methodology/approach

Using a systematic review approach, this research reviewed 172 studies published after 2004. When compared to a comprehensive project success factor framework presented by Chan et al. in 2004, 19 factors are considered new since 2004.

Findings

Though several scholarly outputs highlighted significant improvements to project operations and innovations in equipment and techniques, there has not been a comprehensive oversight since Chan’s et al. (2004) conceptual framework. This paper investigates 16 years of industry changes and identified two new success factors categories (innovation and sustainability) and 19 new factors that add to Chan’s et al. (2004) study. Consequently, a new framework of factors affecting project success was developed.

Originality/value

This paper was very specific in its attempt to find the new and additional success factors for managing construction projects. A new conceptual framework, which includes the newly identified factors, was then developed that will create a greater awareness of stakeholders’ concerns and ultimately contribute to significant improvement in developing project objectives and defining success measures.

Abstract

Purpose

The purpose of this paper is to investigate the literature on resilience factors applied to post-disaster reconstruction projects and to develop a guiding framework to assist in their strategic selection and application.

Design/methodology/approach

A systematic review was undertaken on the literature’s account in four major bibliographic databases to elicit resilience factors contributing to improving post-disaster reconstruction projects' robustness. Through summative content analysis and open-coding of research outputs over the past decade, the factors identified informed the development of a conceptual framework that can significantly impact the built environment’s resilience development process.

Findings

The review found 24 resilience factors open-coded into five criteria groups: governance, innovations, reconstruction approaches, resource management and stakeholder expectations. While these factors have influenced reconstruction projects, the recently increased participation of clients and end-users in construction management accentuates their strategic selection and applications.

Research limitations/implications

The research focused on English language articles; therefore, any claim to a comprehensive resilience factors listing can be amiss. The framework provides a platform for developing clear measurement indicators for allocating project resources and determining resilience deficiencies.

Practical implications

Results confirm the designs and assessment of a resilient built environment extends beyond the traditional structural characteristics, but includes the ability of the integrated network of buildings and infrastructure to support the continuous delivery of the community’s social and economic services in normal and post-disaster settings.

Originality/value

The review is very specific as it attempts to develop a novel conceptual framework for guiding developers and practitioners in the application of resiliency to post-disaster reconstruction projects.

Abstract

Purpose

Although several studies have been conducted on the causes of cost overrun, they have mainly assumed that the causes of cost overrun are independent of each other, and few of them scrutinized the complex interrelationships between the causes. To fill the gap, this study aims to investigate the mutual interactions between the causes of cost overrun using interpretive structural modeling (ISM) and proposing strategies to tackle the causes considering their interactions.

Design/methodology/approach

Critical causes of cost overrun were identified through a comprehensive literature review. In total, 22 key causes are then refined based on the opinions of relevant experts involved in the Iranian building and construction sector. Using the nominal group technique, the causes' interactions were examined and represented via the ISM diagram. The causes were also classified using “matrix cross-reference multiplication applied to a classification (MICMAC)” technique.

Findings

The results showed that price fluctuation, claims, execution delay, delay in payment and change order positioned at the highest level of the obtained model can directly result in cost overrun, and corruption and poor contract management located at the base of the model are two major root causes of cost overruns. It was also concluded that more attention should be paid to the precontract phase of the project to address and prevent corruption and managerial issues deeply rooted in this stage.

Originality/value

The findings of this study provide a clear understanding of how different causes of cost overrun are related to each other and can ultimately assist project managers of different parties in choosing strategies to mitigate cost overrun in building construction projects.
