Abstract

Purpose

The purpose of this study is to systematically analyse and synthesise the existing research published on offsite manufacturing/construction. The study aims to highlight and associate the core elements for adopting the offsite concept in different construction contexts. This ultimately facilitates the enhancement of the offsite uptake.

Design/methodology/approach

The research study was carried out through a systematic literature review (SLR). The SLR was conducted to identify and understand the existing themes in the offsite research landscape, evaluate contributions and compile knowledge, thereby identifying potential directions of future research. The grand electronic databases were explored to gather literature on the offsite concept, lean and agile principles and simulation. A total of 62 related articles published between 1992 and 2015 have been included in this study. The relevant literature was systematically analysed and synthesised to present the emerging offsite themes.

Findings

The descriptive and thematic analyses presented in this paper have identified related offsite research studies that have contributed to setting a firm foundation of the offsite concept in different construction contexts. Each of the 62 articles was examined for achieving the aim and objectives of this study, the method of data collection and coverage of offsite themes. The results of the analyses revealed that the articles mostly provide information on the offsite concept and its definitions (53 per cent) and offsite barriers and/or drivers (27 per cent). However, limited attention has been paid to the integration of lean and agile principles (13 per cent) and simulation (7 per cent) within the offsite concept, which are therefore more open to research within the offsite concept.

Research limitations/implications

The literature review highlights the main themes and components of the offsite construction concept. This forms a solid basis and motivation for researchers and practitioners to build on to enhance the uptake of the offsite concept in different contexts. This study also presents a research roadmap within the offsite concept, along with a recommendation for further research to be conducted using the research framework proposed in this study. The framework could lead to validation of using simulation to integrate lean and agile principles within the offsite concept.

Originality/value

This paper presents a systematic review of the literature related to offsite construction in different contexts. The emerging components, that is, offsite definitions, drivers and/or barriers, lean and agile principles and simulation have been highlighted and discussed thematically. A research framework that enables pursuit of the integration of lean and agile principles offsite through the lens of simulation has been proposed. The framework is expected to open up new opportunities on the effectiveness of offsite development in different contexts.

Abstract

Purpose

This study delves into the dynamics between Agile Response to Change (AR), Adaptive Scoping (AS), Stakeholder Engagement (SE) and Project Performance (PP), with a special focus on the moderating influence of Project Complexity (PC). The research, grounded in a thorough literature review, identifies critical gaps in these areas and examines the extent to which PC moderates the effects of AR, AS and SE on PP, offering new perspectives for managing complex projects.

Design/methodology/approach

The research develops a conceptual model based on a critical analysis of existing literature. A comprehensive questionnaire was designed, incorporating 28 items to measure AR, AS, SE, PP and PC. Data was collected from 136 project managers across various industries, and the responses were analysed using structural equation modelling (SEM) to explore the complex interplay between these variables.

Findings

The analysis revealed that internal AR (ARint) significantly enhances both quantitative (PPqt) and qualitative aspects of PP (PPql). AS and SE were found to positively influence PPql, but their impact on PPqt was not significant. Interestingly, PC was observed to negatively moderate the relationship between ARint and PPql, while its moderating effect on the relationship between ARint and PPql was not significant. The study also notes that PC does not significantly alter the positive correlations between AS, SE and PPql.

Originality/value

This research contributes to the existing body of knowledge by elucidating the relationships between ARint, AS, SE and different dimensions of PP. It uniquely explores the role of PC as a moderating variable in these relationships, offering valuable insights for practitioners and researchers in the field of complex project management.

Abstract

Purpose

The large number of stakeholders in a project is a source of complexity because their inter-relationships can lead to complex interactions, an inadequate understanding of the other stakeholders and conflicting stakeholder interests. Although several studies have investigated the role and effects of engaging stakeholders in improving project success, studies examining the relationships between stakeholder engagement (SE) and quantitative and qualitative project performance (PP) in complex projects (CPs) have been limited. This study empirically examined the relationships between SE and project performance within complex and non-CP contexts.

Design/methodology/approach

The study used an extensive literature review to develop the conceptual model. The study identified 22 factors of measuring SE and project performance’s association within the context of CPs. The literature review followed by a questionnaire survey to collect data from quantifying the relationships. One hundred forty-four responses were received from project managers in different locations. The response data were subjected to structural equation modelling analysis. Confirmatory factor analysis was applied to evaluate the measurements model.

Findings

The current study generated several key findings. In the context of CPs, SE was found to negatively affect quantitative PP but to positively and significantly affect qualitative PP. In non-CPs, SE also positively affects qualitative PP. Further, in the context of CPs, SE negatively affects schedule performance, whereas no significant relationship was found between the two variables in non-CPs. In terms of cost performance, no significant relationship was observed between SE and cost performance for either group.

Originality/value

This research provides insight into differences in the relationship(s) between SE and PP in non-complex and CPs. The research also makes recommendations for project team members.

Abstract

Purpose

Cities are facing challenges with their smart city agenda due to tighter budget constraints, varied interests of different stakeholders and increasing needs of technological innovation. Therefore, cities are partnering with private organisations to advance smart city projects. This research critically analyses the existing research published on public-private partnerships (PPPs) for the development of smart city projects and aims to identify the emerging themes and recommend mechanisms and strategies for improved use of smart city PPPs.

Design/methodology/approach

The content/textual analysis was conducted on 52 research publications relating to PPP and smart city from 2001 to 2020. With the assistance of the Leximancer software, the related literature was systematically analysed and synthesised to present the emerging themes of PPP application within the smart city context.

Findings

The analyses reveal that smart city PPPs mainly concentrated on building new or improving existing infrastructure. The research identifies five themes on PPP application for smart city development: (1) Technological innovation integration and increased risk profile, (2) Smart citizen engagement and participatory governance, (3) Data sharing and information security, (4) Transformation of PPP process and approach and (5) PPPs for urban sustainability. This research consolidates these five themes in a proposed sustainable public-private-people partnership (PPPP) framework.

Originality/value

This research provides a new perspective on rethinking the extant PPP models by highlighting the emerging themes in the PPP application for smart city development. This study provides useful recommendations for smart city infrastructure project partnership and engagement among the public and private sectors, and the city residents.

Abstract

This chapter discusses the profound and influential impact the construction industry has on the national economy, together with the huge negative effect it has on the environment. It argues that by adopting smart and industrialised prefabrication (SAIP), the Australian construction industry, and the construction industry globally, is well positioned to leverage the circular economy to advance future industries with less impact on our natural environment. It discusses aspects of the application of digital technologies, specifically building information modelling, virtualisation, augmented and virtual reality and 3D printing, coupled with reverse logistics as a proponent for advancing the circular economy through smart, digitally enabled, industrialised prefabrication. It further postulates a framework for SAIP for the circular economy.

Abstract

This study delves into the factors that influence the practice of female genital mutilation in West Africa, as well as the health implications. An online cross-sectional study was conducted with the use of electronic questionnaire. The study was targeted at adult females who were between the age of 18 and 50 years old. The Uniform Resource Locator (URL) of the electronic questionnaire was administered on social media platforms (Facebook and WhatsApp) only through convenience and snowball sampling techniques. A sample size of 3,119 adult females participated in the study. Spearman rank correlation (r) was employed to test the hypotheses. Responses were gathered from adult females whom originates from nine West African countries which are Nigeria, Ghana, Mali, Liberia, Benin, Cameroon, Chad, Gambia and Guinea. The study found a strong and positive relationship between culture and the practice of female genital mutilation in West Africa, and there was a weak and positive relationship between religion and education, and the practice of female genital mutilation in West Africa. Despite the health risks, it was revealed that female genital mutilation remained uninterrupted in West Africa. The findings of this study imply that the culture of the people, religious belief system and education are critical factors in efforts to be considered when discouraging the practice of female genital mutilation. Therefore, for healthy living, the practice of female genital mutilation should be discouraged in the study area. Based on the study outcome, recommendations were suggested.

Abstract

Purpose

The purpose of this paper is to examine the multi-dimensionality of women managers’ turnover in the United Arab Emirates. The study argues that several factors besides public policy influence turnover.

Design/methodology/approach

A special survey was developed and administered to a convenience sample of 298 local women managers in both sectors. Descriptive statistics, Cronbach’s alpha, Pearson and multiple regression analyses were used.

Findings

The empirical analyses provided support to the multidimensionality of turnover. In addition, turnover was predicted by a model of eight factors (adjusted R2 = 0.456), namely, economic needs, quality of work life, leadership type and practices, social needs, marital status, organisational satisfaction, organisational commitment and public policy.

Research limitations/implications

The study was rich, empirical data were gathered and analysed along with qualitative literature. Gender remains salient in organisations as human resource policies alone are incapable of retaining women in leadership. Limited sample size and convenience sampling method may limit the generalizability of the findings.

Practical implications

Workplace conditions complement human resource policies; hence, the success of the latter relies on the success of the former. Economic incentives remain significant to motivating managers and retaining women in leadership jobs.

Social implications

Human resource management policies, such as Emiratisation, cannot be successful without empowering women.

Originality/value

The originality of this paper is drawn from using first-hand data to examine the multi-dimensionality argument of turnover in addition to the advancement of gender studies in leadership and management. The study also provided evidence that rationality (i.e. economic means) remains important to retain women managers.

Abstract

Adoption of sustainability principles is crucial for construction project delivery, and various parameters are being used as a yardstick for its measurement. This chapter discusses profit as one of the parameters used to determine the success of a sustainable construction project. It explains such issues as the nature and important of construction industry and its product (construction project), meaning of sustainable construction as well as meaning of profit and what its entails in construction. It reviews the value of profit as a measure of success for a construction project and also encourages the need for planning and analysis of all activities involved on a construction project in relation to its environment so as to validate the profit as a measure of project success.

Abstract

Purpose

This paper aims to investigate the best methods of utilisation of reclaimed asphalt pavements (RAP) in Egypt, to determine the effect of using 100% RAP instead of using virgin aggregates and asphalt; investigate the effect of thermoplastic elastomer polymer as asphalt modifier; and also improve the mechanical and physical characteristics and consequently improving the quality of asphalt paving, increasing service life of asphalt-paving and reducing costs.

Design/methodology/approach

Nano acrylate terpolymers were prepared with different % (Wt.) of and were characterised by Fourier transforms infrared (FTIR), for molecular weight (Mw), by thermo gravimetric analysis (TGA) and by transmission electron microscopy (TEM). A 4% (Wt.) of the prepared nanoemulsion terpolymer was mixed with virgin asphalt as a polymer modifier, to improve and reuse of the RAP. The modified binder was tested. The tests conducted include penetration, kinematic viscosity, softening point and specific gravity. Application of Marshall mix design types; hot mix asphalt (HMA), warm mix asphalt (WMA) and cold in place recycled (CIR). Four different mix designs used; control mix contained virgin asphalt by HMA, and the other three mix designs were polymermodified asphalt sample by HMA, WMA and CIR.

Findings

The research results showed that using 4 Wt.% of the prepared nanoemulsion terpolymer to produce hot mix asphalt (HMA) and warm mix asphalt (WMA) achieved higher stability compared to the control mix and cold in place recycled (CIR).

Research limitations/implications

This paper discusses the preparation and the characterisation of nanoemulsion and its application in RAPs to enhance and improve the RAP quality.

Practical implications

Nano-acrylate terpolymer can be used as a new polymer to modify asphalt to achieve the required specifications for RAP.

Originality/value

According to the most recent surveys, Europe produced 265 tonnes of asphalt for road applications in 2014, while the amount of available RAP was more than 50 tonnes. The use of RAP in new blended mixes reduces the need of neat asphalt, making RAP recycling economically attractive.
