The mediating role of work–family conflict on role overload and job stress linkage

Abstract: PurposeThe present study first explored the different dimensions of work–family conflict and job stress. It then evaluated the mediating role of time and strain-based work–family conflict on the relationship between role overload and psychological stress and role overload and physiological stress.Design/methodology/approachThe study utilized a quantitative data collection approach through a questionnaire design. With the aid of the questionnaire, 308 samples were collected from the project-level staff of ten construction organizations in Sri Lanka. The collected data were analyzed using a structural equation modeling approach to address the research hypotheses.FindingsResults supported the mediating role of work–family conflict on the relationship between role overload and job stress. Specifically, the time and strain-based work–family conflict combined partially mediated the effect of role overload on psychological stress. While strain-based work–family conflict fully mediated the effect of role overload on physiological stress. Hence, the organizations that seek employee well-being should focus on developing a conducive working environment with a focus on a reasonable workload for everyone. Besides, the management should give special consideration to working hours as it affects both the employees' stress levels and family life.Originality/valueThis study added the mediating role of time and strain-based work–family conflict to the previous empirical research on the relationship between role overload and job stress dimensions. Besides, this study discusses the different dimensions of work–family conflict and job stress, which is a less explored area in the construction literature.

A labour performance score and grading system to the next normal practices in construction

Abstract: PurposeThe performance-based utilisation of labour resources is a decisive function for developing characteristics of the next normal in the construction industry. Based on the industry's needs, this study aims to develop a framework for the systematic process of labour performance evaluations and labour grading towards achieving higher productivity in construction operations.Design/methodology/approachBoth qualitative and quantitative methods were applied through a comprehensive literature review, surveys and experts' discussions to develop a set of labour training elements of outcomes. Problem-focused and action-oriented communication approaches were used throughout the study to produce detailed steps for the systematic evaluations of labour performance.FindingsThe study has presented a framework consisting of a set of labour training elements of outcomes with the relative weights, as well as the detailed procedures to assess labour competencies towards the calculations of labour performance score values and labour grading.Research limitations/implicationsAlthough the scope of the study is limited to the Sri Lankan context, the findings may be tested in other countries for upgrading their performance improvement practices of labour operations.Practical implicationsThe study outcomes will strengthen the construction management practices for the successful implementation of labour training and performance evaluations at construction sites, and also contribute to upgrading the vocational training programmes in the country towards the next sustainable normal.Originality/valueThe developed framework can be a functional tool for the construction industry that provides a mechanism to show the detailed cross-section of each labourer's performance and values, and also displays their roles and responsibilities to accelerate the next normal in the construction industry.

Structural equation modeling of the critical driving forces of offsite construction in Ghana

Abstract: PurposeThe construction sector suffers significant challenges which are intertwined with processes and products of the traditional onsite construction approach. The quest for a lasting solution to these problems is heralding the change toward offsite construction. Amid the scaling drive, to date there are no official reports and contribution to knowledge on the drivers of offsite construction in Ghana. This study models the structural paths of the critical drivers of offsite construction in Ghana.Design/methodology/approachData were collected through a questionnaire from 95 respondents in the Ghanaian construction industry. Exploratory factor analysis and Partial least squares structural equation modeling were employed to analyze the data.FindingsThe results revealed that industry dynamics are the governing drivers of offsite construction in Ghana. As such, factors such as the rocketing housing deficits, high cost of acquiring land permanently, high cost of cast-in-situ construction, the utilization of prefabricated shipping containers for construction and construction market demand constitute the governing drivers of offsite construction in Ghana. Similarly, concern for higher productivity is a critical driver of offsite construction in the Ghanaian construction industry. On the contrary, findings show that performance-related drivers, government policy and regulation, and technological innovation exert little influence in driving offsite construction in Ghana.Practical implicationsThe appreciation of the drivers may help stakeholders to understand the important mechanisms underlying offsite construction in Ghana, and thereafter help them to make more informed decisions regarding its implementation.Originality/valueThe findings contribute some interesting dimensions to the global debate on offsite construction by discovering and adding two drivers of offsite construction peculiar to developing countries (high cost of acquiring land permanently, and the utilization of shipping containers for construction) to the literature.

Stakeholder assessment in construction projects using a CRITIC-TOPSIS approach

Abstract: PurposeStakeholder assessment is based on attributes possessed by stakeholders, making the process heavily reliant on evaluating attribute weights. The present assessment methods are based on Analytical Hierarchy Process, Analytical Network Process, and pairwise comparisons that heavily rely on decision-makers’ skills and knowledge. An objective evaluation of attribute weight needs to be done to overcome this challenge.Design/methodology/approachA Multi Criteria Decision Making (MCDM) based approach, through the combined use of Criteria Importance Through Intercriteria Correlation (CRITIC) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methods has been incorporated to objectively evaluate the weights of the stakeholder attributes and their ranking with a specific focus on construction megaprojects. Five stakeholder attributes and twelve commonly associated stakeholders with megaprojects were considered to achieve this.FindingsThe new model presented power, durability and legitimacy as three important stakeholder attributes, further used to determine stakeholder importance. The client, contractor and project manager were identified as the top three internal stakeholders, and customers, local community and utility service providers as three crucial external stakeholders.Research limitations/implicationsThe findings from the proposed method provide the practitioners with updated information about the attributes they need to look into when planning stakeholder involvement and management. Further, it also leads them to the established framework for the provided stakeholder ranking when planning their management strategies.Originality/valueThe use of CRITIC method allowed to address the possibility of any correlation between the attributes in their weight determination. This was one of the advantages as co-relation between the attributes during their weight determination has not been addressed in previous methods.

Awareness of the LEED requirements for green housing development among built-environment professionals in Nigeria

Abstract: PurposeThe study aims to assess the gap in the awareness of the Leadership in Energy and Environmental Design (LEED) requirements for green housing development among built-environment professionals in meeting the housing need in Nigeria.Design/methodology/approachThe study is a cross-sectional survey of built-environment professionals in the Physical Planning Units (PPUs) of Federal Tertiary Educational Institutions in South-Western Nigeria. The LEED v4 scoring system for New Construction and Renovation was adopted for the survey questionnaire on five point Likert scale. Data were analyzed using the MIS and Kruskal–Wallis Rank sum Test.FindingsAwareness of the LEED requirements varies across the categories. Sustainable site is ranked first while innovation and regional priority ranked from the rear. There is variation in awareness among the professionals. The Land Surveyors are followed by the Architects while the Builders ranked last.Research limitations/implicationsThe scope of the study is limited to the professionals in the PPUs in the study area. However, the findings are indicative. The low level of awareness of some of the requirements and the extent of variation among the professionals will negatively impact the integrated design approach and collaborative effort needed for green housing to meet the housing deficit in Nigeria.Practical implicationsThe study is limited in scope. The low level of awareness of the requirements coupled with the extent of variation among the professionals will negatively impact the integrated design approach and collaborative effort needed for green housing to meet the huge housing deficit in Nigeria.Originality/valueThe study takes the lead to assess the awareness of the requirements for green housing development based on the LEED impact categories. Improving the awareness of these requirements will enhance their implementation and consequently impact the quality of housing provision. The professionals need to bridge the knowledge gap to enhance collaboration and productivity for green housing development.

Success in collaborative construction through the lens of project delivery elements

Abstract: PurposeThe emergence of collaborative delivery models and working practices in construction industry has created a potential area for project success research. Previous studies have addressed success factors of various collaborative delivery models (e.g. alliance and partnering). However, there is currently very limited research-based knowledge concerning core success factors for different collaborative delivery models, exploring the commonalities. Thus, this study aims to conceptualize a success model for collaborative construction projects by identifying and structuring their core success factors through the lens of project delivery elements.Design/methodology/approachA systematic literature review was conducted, and thematic as well as content analysis of the relevant studies led to the identification of mentioned success factors in the literature for different collaborative delivery models. Then, those common success factors were structured in a model based on factors' relation to project delivery elements.FindingsThe obtained results present eight core success factors (e.g. equality, mutual trust and commitment to win–win philosophy) for collaborative construction projects, structured in a model based on their contribution toward project organization, contractual relationships, and operational system in construction project delivery. Moreover, the differences between success factors for traditional and collaborative construction projects are discussed.Originality/valueThis study's findings provide insightful theoretical contributions on collaborative construction project success and providing a departure point for future studies based on the discussed differences between success factors of collaborative and traditional construction projects. The findings can be also practically insightful for the project professionals in collaborative construction projects to succeed in managing project organization, contractual relationships, and operational system.

Awareness and practice of the principles of circular economy among built environment professionals

Abstract: PurposeThis study examines the level of awareness and practice of the principles of circular economy (CE) among built environment (BE) professionals in Ghana.Design/methodology/approachA structured questionnaire survey was used to solicit the views of 162 BE professionals working in construction, consulting and developer firms on the issue under investigation. Data were analysed through descriptive and inferential analysis.FindingsThe findings revealed that the BE professionals possessed moderate awareness of the six CE principles (i.e. repair, recycle, reuse, renewable energy usage, reduce and redesign) examined. The findings further revealed that only two out of the six principles (i.e. repair and reuse) received some moderate level of practice among the professionals.Practical implicationsPractically, the findings would be relevant to government, policymakers, researchers and other construction professionals. For the government and policymakers, these findings would inform them on the laws and policies to enact to increase awareness and practice of CE principles. For researchers, these findings will assist in exploring gaps for further studies. For the construction professionals, the findings would inform them of the need to step up measures to practice the various principles of CE in their firms adequately.Originality/valueThis study provides insights into an under-investigated topic in the construction industry worldwide. It offers new and additional insights into the current state-of-the-art practice of CE principles among BE professionals.

Challenges negating virtual construction project team performance in the Middle East

Abstract: PurposeOver the last couple of decades, many organisations are increasingly adopting virtual team concepts, and construction companies in the Middle East are no exception. Members of a virtual team are geographically scattered and represent a diverse range of cultures. Thus, challenging issues emerge more frequently than in a traditional team. There are challenges associated with space and time as well as high client's demand. Therefore, this study aims to identify and probe the causes of the challenges in virtual project teams in the construction industry of the Middle East.Design/methodology/approachA list of challenges was derived through a comprehensive review of relevant literature. Questionnaire survey was conducted with professionals who are involved in construction virtual project teams. Further, the factor analysis technique was used to analyse the survey responses.FindingsThe results show that the challenges in virtual team arrangement in the Middle East construction industry can be grouped into seven categories, namely, organisational culture, conflict within the team, characteristics of the team members, trust within the team members diversity of the team, communication and training, and cohesion in the team. Understanding of these factors will drive the needed platform to support effective virtual project teams in the Middle East.Originality/valueThis study raises the prospect that organisations may establish an environment for team members to achieve higher levels of virtual cooperation by concentrating on these potentially crucial factors. This, in turn, will encourage further innovation and performance within construction organisations.

The new-normal challenges and IPD solutions: a Canadian case study

Abstract: PurposeAccording to the construction literature, the number of projects applying integrated project delivery (IPD) principles is expected to increase in the new-normal era. However, given that the pandemic is not yet fully over, accurate and measurable data are not yet available. Also, there is a lack of empirical studies that could provide guidelines as to the application of IPD principles at the various stages of construction projects. Thus, the goal of this paper is to address this knowledge gap through case studies.Design/methodology/approachThis paper follows a multi-step research methodology, namely, a literature review, case study and focus group discussions in the context of Canadian construction projects.FindingsBased on the conducted literature review and focus group discussions, the authors identified: (1) new challenges in the various stages of the construction projects' life cycle, (2) their related proximity aspects (technological, organizational, geographical and cognitive) and (3) IPD principles that can address the identified challenges within their associated proximities. The results show that IPD relational principles can improve a project's organizational and cognitive proximities, while IPD digital integrative principles can enhance a project's geographical and technological proximities.Originality/valueThis study contributes to the theoretical checklists of challenges that the construction industry has experienced since the beginning of the pandemic, and to the practical guidelines of implementation of IPD principles to meet these challenges. The conducted case studies are timely and relevant, and their results provide new insights for key project stakeholders into the application of IPD to tackle new-normal challenges based on their proximity perspectives.

Buildability attributes for improving the practice of construction management in Nigeria

Abstract: PurposeThe awareness and practice of buildability is still at its infancy stage in the construction sector of developing countries. Information gleaned from literature shows that embedding buildability into practice is beneficial to construction projects. This study seeks to examine the buildability attributes that are important for improving the practice of construction management.Design/methodology/approachA questionnaire was developed to address the aim of the study. Data were collected through the administration of questionnaires to purposively selected group of architects, engineers, builders and quantity surveyors. A total of 368 questionnaires were administered and a response rate of 60% (219 questionnaires were returned) was achieved. Descriptive and inferential statistics were used in analysing the data.FindingsThe results revealed that discussion centred on buildable designs among builders and designers as the most critical attribute of buildability for improving the practice of construction management in the Nigerian construction industry. The finding also revealed that, there is a statistically significant agreement between different groups of construction organisations in Lagos state, Nigeria concerning buildability attributes for improving the practice of construction management.Originality/valueThis study highlights the buildability attributes which are important for improving the practice of construction management. An understanding of these attributes is essential for improving and embedding buildability as a practice in the construction industry.

Adaptability capacity framework for sustainable practices in the Ghanaian construction industry

Abstract: PurposeThe urgent need to preserve the ecosystem, which faces a threat from non-environmentally-friendly anthropogenic activities, has led to the study of adaptive capacity implementation. There is an indication that the construction industries in developed countries are relatively better equipped to pursue sustainable construction than those in the developing world. Despite this, sustainable construction is yet to be established in developing countries. This research aims to develop a framework to drive and enable small and medium-sized (SME) firms in Ghana to implement adaptive capacity.Design/methodology/approachThe study adopted a quantitative approach, and 400 responses were retrieved as a sample size for which a six-factor adaptive capacity implementation framework was arrived at for SMEs in the Ghanaian construction industry. The data gathered from the respondents were analysed using IBM SPSS version 26 and AMOS version 24, and a structural equation modelling was also used to determine the work's validity based on the AMOS software.FindingsThe findings revealed that education and training, government support and a centralised information hub significantly influence adaptive capacity outcomes in Ghana.Practical implicationsIt is recommended that the government, corporate and professional institutions that desire to preserve the country's ecosystem be guided by this study's adaptive capacity implementation framework.Originality/valueThis study's novelty also lies in the integrated framework for adaptive capacity implementation developed to aid small- and medium- sized enterprises in Ghana's construction industry to ensure environmentally-friendly construction activities.

Establishing underpinning concepts for integrating circular economy and offsite construction: a bibliometric review

Abstract: PurposeCircular economy (CE) and offsite construction (OSC) are two innovations for improving the construction industry's overall performance against a myriad of sustainability-driven agenda/initiatives. There is a real opportunity to conjoin OSC and CE to provide new insight and opportunities to deliver more evidence-based sustainable systems. This study analyses extant literature in CE and OSC (between 2000 and 2021) through a bibliometric review to tease out critical measures for their integration and transformation.Design/methodology/approachThis study adopts a science mapping quantitative literature review approach employing bibliometric and visualisation techniques to systematically investigate data. The Web of Science (WoS) database was used to collect data, and the VOSviewer software to analyse the data collected to determine strengths, weights, clusters and research trends in OSC and CE.FindingsImportant findings emerging from the study include extensive focus on sustainability, waste, life cycle assessment and building information modelling (BIM), which currently serve as strong interlinks to integrate OSC and CE. Circular business models, deconstruction and supply chain management are emerging areas, with strong links for integrating CE and OSC. These emerging areas influence organisational and operational decisions towards sustainable value creation, hence requiring more future empirical investigations.Originality/valueThis study is a novel research using bibliometric analysis to unpick underpinning conduits for integrating CE and OSC, providing a blueprint for circular OSC future research and practice. It provides the needed awareness to develop viable strategies for integrating CE in OSC, creating opportunities to transition to more sustainable systems in the construction sector.

Evaluating the impact of constraints on project success: empirical study of highway projects

Abstract: Purpose Highway projects in India have a history of cost overruns and delay in project delivery, thus incurring huge losses to public funds. The study aimed to measure the extent of influence of various constraints on the overall success of highway projects (e.g. National highway project, state highway projects and major district roads). Based on the literature, various factors were grouped under three categories (a) Project Constraints, (b) Project Governance Constraints and (c) Stakeholder Induced Constraints. Design/methodology/approach A quantitative approach was adopted. A questionnaire-based survey was conducted with 435 respondents from the field of highway projects with a minimum experience of 1 year as Project Manager. The data was analyzed by partial least squares structural equation modeling technique. Findings It was identified that the impact of project constraints (ES = 0.313) on project success is more than that of project governance constraints (ES = 0.231) and stakeholder induced constraints. Additionally, it was found that project governance constraints have a strong impact on project constraints (ES = 0.535) and stakeholder induced constraints (ES = 0.403). Originality/value The study presented in this paper is first of its kind to measure and articulate the impact of project governance constraint, project constraint and stakeholder induced constraints on project success.

Integrating sustainability practices into the Irish construction supply chain: main contractors' perspective

Abstract: PurposeThe low level of sustainable practices in the architectural, engineering and construction (AEC) sector continues to increase. In driving sustainability practice adoption and implementation, construction-contracting firms have introduced sustainability practices to their supply chain network. This study examines the strategies adopted by large construction-contracting firms in Ireland to integrate sustainability practices into their supply chain.Design/methodology/approachThe study adopts the mixed-method approach using questionnaires and interviews to collect data. The relative importance index (RII) was used to analyse the data collected through the questionnaire survey. In terms of theoretical underpinning, the study was positioned in the resourced-based view (RBV) theory, which focusses on the link between a firm's internal characteristics and performance.FindingsThe results revealed that, in building a long-term relationship, trust, knowledge of the construction process, commitment, a common goal and mutual support were the key factors considered. While in developing their supply chain, suppliers' assessment and promoting competition in the supply chain were ranked high amongst the mechanisms utilised. Additional findings revealed that long-term relationships with a supply chain organisation have little impact on the project sustainability performance; instead, close collaboration and trust amongst the project team influenced the project sustainability performance.Research limitations/implicationsThe study focusses only on the main contractor's organisation. Further study will require exploring the supply chain organisations to provide a deeper understanding.Practical implicationsThe research demonstrates that for construction-contracting firms to contribute positively to sustainability objectives, they will have to collaborate closely with their supply chain.Originality/valueThe study provided practical and empirical evidence to guide construction-contracting firms to develop strategies to drive and implement sustainable construction practices.

Framing the barriers to construction industry transformation

Abstract: Purpose“Transforming construction” is a wide-ranging strategic term, under which sit numerous initiatives. It is the latest, in a long line of strategies and reports introduced to with the intention of industry improvement. Arguably, many of these fail to achieve their aim. The barriers preventing the adoption of transforming construction initiatives are therefore limiting the potential benefits of the strategy. The aim of this research is to formally identify and understand how these barriers are framed and how these frames can be changed so that the barriers can be overcome, and the wider strategy benefits realised.Design/methodology/approachA literature review is undertaken to identify “transforming construction” initiatives. A total of 15 semi-structured interviews are then undertaken with construction professionals and analysed via narrative analysis to identify and understand perceived barriers to these initiatives. Framing is utilised as a theoretical lens to categorise these barriers and understand how “shifts” in the frames held can be achieved and the barriers overcome.FindingsBarriers to transforming construction initiatives are identified as wicked problems. This allows a new perspective on such initiatives to be gained. The results also reveal how construction professionals frame such barriers, viewing themselves as bystanders with initiatives and practices “bigger” than themselves and their roles. How these frames can be “shifted” from bystander to active participant is identified. Such a shift can serve as a blueprint for industry professionals so that the initiatives identified can be successfully implemented thereby increasing the success of the transforming construction strategy.Originality/valueThis paper addresses a gap in current research around the perceptions held by construction professionals of the initiatives that sit under the transforming construction strategy. Addressing this gap allows the diagnosis of barriers that have previously served to prevent initiatives gaining traction. The findings contribute to both the existing literature and current industry practice by highlighting how the barriers are framed, and how such frames can be “shifted” to support the realisation of long promised strategy benefits.

Modeling of planning function management in Vietnam’s public construction works

Abstract: PurposeThe planning function is a central component of management principles, enabling the success of construction project management. Many works have been highlighting the topic of critical success factors within construction organizations, yet the results have rarely covered planning behaviors within public construction work management; these less investigated areas were the aims of this study.Design/methodology/approachTo fulfill this research aim, seven attributes of planning function were first derived through focus group studies, a focused literature review and focal interviews with industry practitioners. Then, a regression analysis design was employed with data collected from 139 professionals who are involved in public construction works management in Vietnam. The structural equation modeling technique with partial least-squares estimation was utilized to analyze the data.FindingsThe results revealed seven behavioral dimensions (i.e. Goals planning (PL1), Planning guidance (PL2), Strategic planning (PL3), Financial mobilization (PL4), Action plan (PL5), Expenditure planning (PL6) and Responsibility assignment (PL7)) to measure planning function management in terms of public construction works. The study also reveals that Goals planning (PL1), Financial mobilization (PL4), Expenditure planning (PL6) and Responsibility assignment (PL7) have significant effects on management effectiveness. At the same time, Goals planning (PL1) acts as the mediator of Planning guidance (PL2) and Strategic planning (PL3); while Action plan (PL5) specifies an indirect influence through the mediator of PL4, PL6 and PL7.Originality/valueThe success of this approach is expected to reinforce the contribution of the planning function and suggest a useful tool for supporting the professionals in managing public construction works.

Challenges to energy transitioning in commercial buildings in the Nigerian built environment – from generator to RETs economy

Abstract: PurposeChallenges to energy access in Nigeria have resulted in the widespread use of fossil fuel generating sets (generators) despite its renewable energy (RE) potential. Given the climate crisis, combined with the country's rapid population growth and expected rise in energy and building demand, transitioning to low-carbon electricity using REs like solar photovoltaic (PV) presents opportunities beyond securing its energy future. While PV use is growing in Nigeria, this is focused on the residential sector despite the identification of the commercial sector as a high energy consumer and a key platform for its integration. In line with this, this research aims to investigates the challenges to energy transitioning from generators to solar PV in commercial buildings.Design/methodology/approachA qualitative approach in line with grounded theory was adopted using in-depth face-to-face interviews with industry experts.FindingsTwo distinct but interrelated categories emerged: being held captive and being a saviour that represented a duality of systems, and/or processes formed the core category “Hostage Syndrome”. The core category (theory) was generated based on the explanations and expressions by participants about their concerns, interests, and the conditions under which they operate. The findings reveal the value attributed to generators beyond an operational role and the adjustments or mechanisms adopted by building professionals during their practice. It suggests a sphere of influence beyond the obvious financial and/or institutional aspects, as determining factors to what is viewed as sustainable which will be key to transitioning to REs.Originality/valueThis paper provides new and in-depth insight into understanding the conditions under which building professionals operate associated with their interpretations of “being sustainable”. The study highlights the need to consider psychological and cultural factors in the development of interventions, strategies and/or policies to support RE transition, particularly towards achieving a sustainable construction industry.

An assessment of prevalence of poor sleep quality among construction workers in Southern India

Abstract: PurposeSleep quality has been associated with health and safety issues influencing construction labour productivity in developing countries. Despite its significantly adverse contribution to these facets if left unattended to, limited studies have sought to establish its prevalence and causal factors in labour-intensive contexts. This study aims to bridge the gap between the prevalence and casual factors of poor sleep quality among construction workers.Design/methodology/approachAdopting a case study research design, data were collected from a randomly selected sample of construction workers (n = 475) recruited from four construction-based corporations in Southern India. Self-administered questionnaires comprising a Pittsburgh Sleep Quality Index (PSQI) scale was used to measure sleep quality among respondents alongside demographic characteristics, lifestyle preferences and work-habits data. Data were analysed using multivariate logistic regression analysis and descriptive statistical techniques.FindingsSlightly more than a third of the construction workers (n = 33.9%) surveyed experienced poor sleep quality based on a PSQI method score of = 5. Also, the nexus between demographic characteristics, lifestyle preferences and work habits on the incidence of poor sleep quality among construction workers was confirmed.Practical implicationsThe study contributes to the contemporary discourse on improving sleep health of construction workers to enhance their well-being thereby enabling their contribution towards achieving improved construction labour productivity.Originality/valueThis study makes an original contribution to the extent that it seeks to not only determine the prevalence of sleep quality within the construction industry and associated causal factors but to explore its implications on construction labour productivity.

TOPSIS analysis for sustainable redevelopment potential of abandoned infrastructure in Nigeria

Abstract: PurposeAbandonment poses a range of effects detrimental to the development of a country such as Nigeria. Restoring such infrastructure in a sustainable manner is a challenge identified in the literature. The aim of this study is to evaluate a novel approach – the technique for order preference by similarity to an ideal solution (TOPSIS) to identify the sustainability criteria for the redevelopment of abandoned infrastructure in Nigeria. The literature evidences use of TOPSIS in various development contexts, but not in the context of redevelopment of abandoned infrastructure.Design/methodology/approachThis study explores the potential of TOPSIS in the sustainable redevelopment of abandoned infrastructure in Nigeria through a combination of a quantitative method of data collection – questionnaire – and a case study. The case study focuses on the abandoned Federal Government Secretariat in Lagos. One hundred and sixty-one (161) participants responded to the questionnaire. Data collected were analyzed using TOPSIS analytical technique.FindingsRefurbishment is considered as the most sustainable alternative for the redevelopment of abandoned infrastructure. For criteria consideration, structural integrity and foundation categorized under the technological attributes ranked highest for refurbishment and conversion alternatives. Waste generation and prevention and profitability top the list for demolition and procurement respectively.Social implicationsThe social benefit of this study is to bring building considered to be an eyesore back into use.Originality/valueThe findings from the analysis orchestrates the importance of the built environment research concentrating on innovative frameworks for sustainable redevelopment of abandoned structures in the construction industry.

Dynamics of PPP investment in energy and country governance: evidence from Sub-Saharan Africa

Abstract: PurposeThis paper intends to investigate the empirical link between governance and energy investment in PPP. To succinctly account for biases in the fixed effects (FE) model, the authors adopted different bias-corrected techniques. The majority of these techniques provided evidence that PPP investments in energy are boosted by increasing the desire for accountability, prioritising the voice of the masses and disabusing the rule of laws. This study could not find any positive influence from the control of corruption to PPP investment in energy.Design/methodology/approachThe acute shortage of power supply in SSA has attracted PPP investments in the energy subsector of the economy, leading to the recent debate on governance and public, private investment. The authors contributed to this argument by examining the impact of country governance on PPP investment in energy using a sample of countries in SSA.FindingsTherefore, the authors concluded that low control of corruption is responsible for the inadequate volume of PPP investments. In the light of this, the government should redefine the anti-corruption bill of their sovereignty to accommodate severe sanctions when necessary.Originality/valueThis paper uses the fixed effects (FE) model by introducing batteries of nonlinear panel models to capture the relationship between the impacts of country governance on PPP investment in energy.

Impact and awareness of COVID-19 on rural communities – an empirical study of India

Abstract: PurposeTo study the impact, awareness and preparedness of COVID-19, a “pandemic” that has aroused the attention of the entire world because of rapid infection rates; among the targeted rural communities as basis to analyze their self-sustainability level.Design/methodology/approachA mixed methodology/approach combining critical literature review and questionnaire-based survey has been followed in two villages, covering a sample of 150 households located in Solan district of Himachal Pradesh, India. The parameters were selected to check awareness/preparedness regarding basic guidelines, immunity, requirements of essential facilities to deal with COVID-19 patients, the effect of lockdown on social and financial status, difficulties in education.FindingsThe villages have the potential to transform into Smart Villages or Smart Communities with the adaption of self-sustainable processes. The self-reliance on agriculture and traditional lifestyle in targeted rural areas make them relatively safer as compared to the urban areas. The community's overall awareness about COVID-19 and its preparedness was found satisfactory, with some variations that require more innovative strategies with academic interventions.Research limitations/implicationsAlthough the scope of the study was limited to two remote villages of Himachal Pradesh (India), the results could be generalized for in-depth understanding about other villages in the state to convert them into smart villages.Originality/valueIt summarizes a systemic perspective based on selected parameters on how COVID-19 lockdown has affected different aspects of life in rural communities. Further, collaborative efforts and adoption of self-sustainability model can lead to the remarkable transformation of villages into smart villages.

Analysing value creation in social housing construction in remote communities – application to Nunavik (Canada)

Abstract: PurposeRemote and isolated indigenous communities in Nunavik (Canada) currently face a number of housing related challenges. This paper proposes a conceptual framework to identify the factors affecting value creation within the supply chain of social housing construction in that region. The term “social” refers to the fact that governments subsidise construction and operation of these buildings intended for low-income households.Design/methodology/approachThe research used a literature review and information collected from 3 semi-structured interviews with key stakeholders to identify the desired features of improvement or solutions (e.g. prefabrication) with respect to value creation. A SWOT analysis, an influence/dependence map and a causal loop diagram were developed to represent the supply chain.FindingsLocal job creation and the number of buildings to build were identified as the key factors that can roughly represent value creation. Energy resources, construction time, type and amount of labour force, shipping constraints, number of replacement parts and waste disposal were identified as the main factors constraining the range of solutions to implement.Practical implicationsThe framework can be used to support the decision-making in supply chain management and the design of solutions for remote areas such as Nunavik.Originality/valueThis paper is the first to analyse value creation in social building construction in remote and isolated communities such as those from Nunavik. Conceptual models achieved within the framework allowed identifying the factors that could roughly represent this value creation, as well as logical relationships that link them with other factors.

Modeling the Indian households' intention to adopt the solar net metering system

Abstract: PurposeThe present study aims to develop and offer a model to evaluate the customers' attitude and intention to adopt solar net metering systems (commonly called solar NMS) in a developing economy. Therefore, the research examines different factors affecting the Indian households' attitudes and intention to adopt solar NMS.Design/methodology/approachThe data were collected from 247 solar NMS users from India. The structural equation modeling (SEM) technique was applied using SmartPLS 3.3.2 software to analyze the impact of various factors on their adoption intention. The conceptual model comprises environmental concern, perceived ease of use (PEOU), subjective norms, perceived usefulness (PU), attitude and behavioral intention to adopt solar NMS.FindingsSubjective norms and environmental concerns significantly influence the PU and PEOU of solar NMS. Also, PU and PEOU significantly influence their attitude and intentions toward adopting solar NMS. Thus, the perceived social pressure and environmental concern affect their perception of solar NMS's usefulness and ease of use, leading to favorable attitudes and adoption intentions. Additionally, the solar NMS benefits the customers, society and the environment by enhancing environmental quality, compatibility with the modern lifestyle, and reducing dependency on the power grid and electricity bills. These benefits shape the customers' overall perception and increase the adoption of solar technologies.Originality/valueThe present research helps bridge the gaps in the existing literature by identifying (1) factors affecting customers' intention toward solar technologies in developing nations and (2) describing the significant prediction of environmental concern and subjective norms to increase solar technologies adoption.

Sustainable hydroelectric power project planning under socio-economic and environmental concerns using Index based approach

Abstract: PurposeThis study aims to identify and gauge the sustainability indicators (SUSIs) for sustainable Hydroelectric Power (HEP) project development. It examines major SUSIs under the social, economic and environmental (SEE) fronts and categorizes them under push and pull impacts which helps to identify challenges and opportunities associated with projects. Additionally, the study calculates an empirical sustainability index (SI) to assess the sustainability level of HEP. Finally, the study suggests mitigation measures across stakeholders, which will optimize government/developer/investor investments.Design/methodology/approachThis paper examines the interaction of sustainable HEP development with SUSIs using Uttarakhand as a study area. Additionally, SI has been developed quantitatively. For the indicator classification, the authors conducted a literature review and secondary survey of all affected parties, including investors, developers, NGOs and villagers. The fuzzy logic theory (FLT) is used to determine the SI of the study area and classify projects in their level of sustainability. On the basis of expert opinion and literature review, mitigation measures are proposed across stakeholders.FindingsThe authors found that there is a mixed effect of SUSIs on HEP development across various projects in Uttarakhand. Furthermore, the authors suggest that index-based assessment and planned collaboration play a significant role in sustainable HEP development.

Application of decision support tool in design-build projects: a quasi-experiment with novice decision makers

Abstract: PurposeDesign-Build (DB) is known as the alternative for Design-Bid-Build in the Malaysian construction industry. For DB projects, it is critical to adopt effective decision support tool to ensure the execution of a systematic decision-making technique. This study aimed to examine the impact of a decision support tool for novice decision makers to reject or adopt DB for their construction projects.Design/methodology/approachLiterature review and qualitative input from experts identified several key-selection factors pertaining to critical success factors and design-build drivers. This resulted in the development of Decision Support Tool for Design-Build (DST-DB). A quasi-experiment, which involved 382 novice decision makers in the construction industry, was conducted to test the DST-DB quantitatively. The participants were required to compare two construction projects using DST-DB and traditional decision-making methods. Multivariate analysis was performed to analyse all collected data.FindingsThe quasi-experiment data suggests that DST-DB enables significantly higher usability, likelihood, precision, confidence and satisfaction rate when compared to the traditional decision-making process. The pre- and post-surveys indicated that the DST-DB is effective in improving decision-making performance through selection factors of client-briefing, maximised resources and sharing expertise. The participants also agreed that DST-DB is easy to use and helps them to gain better understanding of the decision-making process for construction projects.Originality/valueThis research contributes to the existing body of knowledge through the impact of DST on the decisions of novices. The novice decision makers found that DST-DB is practically adaptable and comparatively effective for decision-making process than traditional decision-making methods. This contributes to the practical application of construction companies to provide DST-DB training to the fresh graduate employees to enhance their competencies in the decision-making process.

Human capacity building strategies for improving PPP implementation in Tanzanian construction projects

Abstract: PurposeImplementation of public–private partnerships (PPPs) in African projects is inundated with a number of capacity building challenges which affects growth and project performance. Further, there is paucity of empirical studies on the strategies for overcoming these challenges. Therefore, this research addresses that knowledge gap by examining the human capacity building (HCB) strategies for improving PPP implementation in construction projects in developing countries, with a focus on Tanzania.Design/methodology/approachHCB strategies identified from the scoping review were administered to 81 handpicked Tanzanian practitioners attending PPP training course. To examine the differences in the perception of the identified HCB strategies, and the relationships between different pairs of the HCB strategies, the data were subjected descriptive statistics, parametric tests, Kendall’s concordance and Pearson correlational analysis, including group wise correlation analysis.FindingsBased on the overall sample, “Engagement of stakeholders on capacity development”, “Organization of PPP seminars and training” and “Introduction of in-house training to Public institutions expected to undertake PPP projects” are the top ranked HCB strategies. “Development of study tours to stakeholders involved in PPP projects” is the least ranked. Significant differences between the sub-groups of “no PPP experience” and “some PPP experience” were evident for “Invitation of International experts to share experiences” and “Sharing of responsibilities” HCB strategies. The “no PPP experience” group rated both strategies higher than those with “some PPP experience”.Practical implicationsThe identified HCB strategies can be used as a “road map” for the development of appropriate engagement strategies with various stakeholders for the successful implementation of PPP thereby, enhancing the performance of the construction firms.Originality/valueEight strategies have been identified from the literature and tested for the Tanzanian context. The uniqueness of Tanzanian PPP implementation context arising from varying cultural, organizational, political and economic conditions differentiates the priority of HCB strategies when compared to other contexts where these strategies were investigated. This is germane to the PPP research.

Key components of successful post–hurricane reconstruction of transportation infrastructures

Abstract: PurposeIn the aftermath of hurricanes, the damage levied on transportation infrastructures increases the timeliness of emergency responses and recovery procedures, making it essential that they are reconstructed as quickly as possible – on time and within budget. The aim of this study was to determine significant performance indicators (PIs) that considerably affect cost and schedule performance as well as reworks in post–hurricane reconstruction of transportation infrastructure including highways, bridges, roadways, etc. Additionally, the determined PIs were clustered to investigate key components.Design/methodology/approachThe root causes of reconstruction projects' poor performance were identified through the existing literature, and 30 transportation infrastructure case studies were analyzed to determine the significant PIs that corresponded to cost, schedule performance and reworks. The factor analysis method was used to cluster the significant PIs and determine the key components affecting them.FindingsEight key components were found for cost, eight for schedule performance and six for reworks. The key components of cost performance are shortage of resources, information management, coordination, safety, location, quality of materials, quality of resources and project complexity. The key components of reconstruction schedule performance are human resources, risk management, work suspension, material resources, productivity, on-site inspections, geometrical characteristics and level of reconstruction complexity. The six key components of reconstruction reworks are logistic management, pace of decision-making, accommodation for staff, environmental issues, available temporary paths and volume of debris.Originality/valueThe outcomes of this research will assist authorities and decision makers in identifying and evaluating the critical root causes of poor cost performance, poor schedule performance and reworks and will enable them to facilitate the timely and effective allocation of resources.

Enablers for facilitating life cycle assessment: key stakeholder perspectives of Sri Lankan construction industry

Abstract: PurposeDespite the desire to improve the sustainability of the construction industry, Sri Lanka is still plagued by the low-level adoption of essential methods such as Life Cycle Assessment (LCA) in building and infrastructure delivery. It is indispensable to investigate enablers for facilitating LCA because identification of enablers is a crucial step in the implementation of LCA. This study aims to analyze internal and external enablers for facilitating LCA for the Sri Lankan construction industry from the perspective of five stakeholder categories (academia, government, construction industry, society and environmentalists) and also aims to develop strategies to strengthen the enablers.Design/methodology/approachAn explanatory research design was used. The five stakeholder categories identified above, whose contribution is essential for implementing LCA in Sri Lanka, were selected for data collection. A total of 20 semi-structured interviews were held representing each stakeholder category. The Repertory Grid Interview (RGI) technique was utilized and data analysis was performed using content analysis.FindingsThe results revealed that “ability to identify opportunities for environmental improvements as an extremely important internal enabler for all stakeholder categories” and “the positive growth in the country to achieve environmental sustainability”, “the availability of standardized LCA guides and handbooks” as extremely important external enablers for all stakeholder categories for facilitating LCA in the Sri Lankan construction industry. Further, strategies including making people aware of the LCA concept and development of the LCA database, etc. were proposed to strengthen the enablers.Practical implicationsKnowledge generated through this study would enable the abovementioned stakeholders to make informed decisions to promote the implementation of LCA in the Sri Lankan construction industry. Further, the results of this study have raised awareness of the issues that Sri Lanka will need to solve to expand the LCA applications.Originality/valueSo far, research on LCA has not looked into enablers that can facilitate the implementation of LCA in the Sri Lankan construction industry. This research provides a comprehensive view of the internal and external enablers for facilitating LCA from the perspective of five stakeholder categories and identifies enablers that led the abovementioned stakeholders to pursue the implementation of LCA in the Sri Lankan construction industry. The study also proposes strategies for strengthening the enablers.

Evaluation of weather-productivity models of construction labour for tropics

Abstract: PurposeWeather is one of the main factors affecting labour productivity. Existing weather-productivity models focussed on hot and cold climates paying less attention to the tropics. Many tropical countries are expected to be the most areas affected by accelerated climate change and global warming, which may have a severe impact on labour health and productivity. The purpose of this paper is to assess whether the existing models can be used to predict labour productivity based on weather conditions in the tropics.Design/methodology/approachFive models are identified from the literature for evaluation. Using real labour productivity data of a high-rise building project in Malaysia, the actual productivity rate was compared with predicted productivity rates generated using the five models. The predicted productivity rates were generated using weather variables collected from an adjusting weather station to the project.FindingsCompared with other models evaluated in this paper, the United States Army Corps of Engineers (USACE) was found to be the best model to predict productivity based on the case study data. However, the result shows only a 57% accuracy level of the USACE model indicating the need to develop a new model for the tropics for more accurate prediction.Originality/valueThe result of this study is perhaps the first to apply meteorological variables to predict productivity rates and validate them using actual productivity data in the tropics. This study is the first step to developing a more accurate productivity model, which will be useful for project planning and more accurate productivity rate estimation.
