Aibinu","doi":"10.1108/bepam-03-2022-0039","DOIUrl":"https://doi.org/10.1108/bepam-03-2022-0039","url":null,"abstract":"PurposeThis study aims to develop an ex-post impact evaluation method for public-private partnership projects (PPP) that addresses one of its main difficulties: the multiplicity of perspectives and stakeholders that exist in these projects.Design/methodology/approachThis study first developed a conceptual evaluation framework called ‘Project Success Evaluation Pyramid Model’ (PSEPM) that was designed using a Design Science approach. Second, an impact evaluation method was designed based on the PSEPM. This evaluation method was tested and refined using three PPP projects. This article presents the refined conceptual model PSEPM, the evaluation method and one of the three tests: the PPP toll road.FindingsThe impact evaluation method describes how to evaluate the impact of an existing mega project from the perspective of multiple stakeholders and isolate the impact of the procurement method. Its application in practice is demonstrated with a PPP toll road project in Chile, in which 11 stakeholders were identified. Issues such as city segregation, deficient business model, the relevance of infrastructure availability, and deficient service-fee strategy were identified in the project. The evaluation method provides a judgement about the use of the PPP procurement method and about the overall impact of the project, reconciling the stakeholder perspectives.Originality/valueThe use of this approach could give greater clarity and legitimacy to the discussion over the use of PPPs by evaluating existing projects beyond the use of traditional time and cost measurements. Its originality is the systematic recognition and identification of stakeholder motives, purposes, and judgements over a project.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46469630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Crisis management in public–private partnerships: lessons from the global crises in the XXI century","authors":"G. Castelblanco, J.

In this context, the purpose of this paper is to expose the PPP-crisis research agenda by combining bibliometric and network analyses.Design/methodology/approachThe PPP literature associated with global crises between the 2008 global financial crisis and 2022 was analyzed in three stages: (1) paper selection and screening for the inclusion/exclusion of articles relevant to this research, (2) semantic network development for examining thematic relationships among selected papers by considering the co-occurrence of keywords within the chosen studies and (3) calculation of network metrics for analysis.FindingsThe paper identified six research avenues for the PPP-crisis agenda: public interest, relational governance, risk management, user-pay PPPs, crisis management and financial performance. The PPP-crisis literature has spread significantly in the last five years driven by the case study approaches on a national or regional basis. Conversely, non-crisis periods generate room to strengthen user-pay PPPs and relational governance. The pandemic and post-pandemic times shared the priorities of the 2008 financial crisis but also strengthened the management of the risks and the structural drivers of the global crisis.Originality/valueThis study demonstrates that during global crisis periods, the public interest and financial performance gain relevance in a detriment of structural solutions to social legitimacy erosion of PPPs because of the urgency of giving tools to the public and private sectors to tackle the financial issues, which steer future issues for PPPs.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46862086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the purpose of the study is to map-out from these analyses, the attributes of project clients that motivate contractors' bid decision.Design/methodology/approachA total of 50 responses were obtained from a questionnaire survey. 50% of participants are contractors. 44% are claims consultants, whilst 6% are manufacturers and clients. Beyond measures of central tendencies, analysis focussed on causal relationships by way of correlation, analysis of variance and reductionism.FindingsAll 20 factors considered have significant correlations with at least one other factor. Findings also show the factors can be clustered into six: reputation, financial strength, relationship with the bidder, organisational attributes, history with project attributes and project organisation.Practical implicationsEvidence suggests stakeholders have often struggled to consider the many decision factors reported in normative literature, numbering hundreds. By clustering the factors into sub-themes, bid decisioning has been made more efficient. The study also explains how client attributes could determine project success and contractor participation. Different stakeholders can use findings of this study for training and further studies.Originality/valuePrevious studies have considered bid decisioning indexically – factors were long, analyses were largely inconclusive, and causal relationships are orthogonal. Findings in this study have shown depth: 20 originating client-specific factors were clustered into six sub-themes, and correlations were established. The methodology used for the study is confirmatory and conclusive.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":"1 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41345831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines and confirms the strategy with the most significant impacts on the identified barrier to sustainable construction practice (SCP).Design/methodology/approachThe study deployed a questionnaire survey to evaluate the perspective of 100 construction actors on the barriers and strategies of sustainable construction practice in Nigeria. Factor Analysis was employed to categorize key barriers and strategies into their underlying clusters for further analysis. Partial least squares-structural equation modelling (PLS-SEM) was used to confirm the construct's significant relationship and magnitude, thereby establishing the strategies with the highest impacts on the barriers to sustainable construction practices.FindingsThe findings revealed three clusters of barriers and four groups of strategies to SCP, including technopolitic barrier, perception and awareness barrier and sociocultural barrier. For the significant strategies, education and training, stakeholder regulation, incentive support and government and legislative support strategies were established. Overall, education and training strategy was identified as the most dominant and effective strategy to mitigate the barriers of SCP in Nigeria.Originality/valueThe paper establishes education and training as the key strategy to achieving sustainable quest in the AEC industry. The practical implication is that policymakers, educators and professional bodies can harness sustainable knowledge transfer through education and training to improve sustainable construction practices in Nigeria.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47029832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Exploring the application of BIM in Tanzanian public sector projects using social network analysis","authors":"A. Abdallah, H. Doloi, D. Holzer","doi":"10.1108/bepam-01-2023-0026","DOIUrl":"https://doi.org/10.1108/bepam-01-2023-0026","url":null,"abstract":"PurposeThe present study employs social network analysis (SNA) to demonstrate the extent to which various building information modeling (BIM) functions can be used to address significant issues faced by the Tanzanian public sector construction projects.Design/methodology/approachThis study adopted secondary data obtained from a comprehensive literature review on core BIM functions and the underlying issues faced by the Tanzanian public sector construction projects. This study then adopted SNA for associating the BIM functions with relevant construction issues.FindingsFor Objective 1, the findings revealed that BIM can address 68% of significant issues faced by the Tanzanian public sector construction projects. For Objective 2, the findings revealed that the identified functions mainly addressed issues in the early phases of the project. Finally, for Objective 3, the most effective function was “spatial coordination.”Research limitations/implicationsThis literature-based study does not fully capture both the current contextual issues faced by the industry and the BIM capability of stakeholders involved. In addition, this research does not distinguish between public project size and type which can influence the types of issues faced and consequently the use of BIM function. Accordingly, the research presented in this study needs to be complemented by on-the-ground feedback of industry stakeholders and needs to investigate how project size and type impacts the types of issues that emerge and the use of BIM.Practical implicationsWith respect to practice, the findings of the present study highlight key BIM functions practitioners can begin to target.Social implicationsIn Tanzania, public sector construction projects contribute greatly to social development of Tanzania's population. Owing to the current state of public sector projects underperforming and the negative impact the projects have on the country's development, an intervention measure such as BIM has the potential to enhance the effective and efficient delivery of these projects and thereby promote the social development of the country's population.Originality/valueWith respect to theory, this study demonstrates how core functions of BIM can be mapped with various construction-related issues in order to evaluate the efficacies of the BIM-based investments for improving overall performance in the public sector projects. With respect to practice, the method illustrated in the present study can be applied by policymakers and practitioners to identify core BIM functions to target to address pressing contextual issues faced by public sector projects in the respective contexts.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44883054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to investigate the barriers to EIA implementation for construction projects in Nigeria.Design/methodology/approachThe study adopted a survey research technique. The snowball sampling approach was adopted to identify key stakeholders in EIA practice for the administration of questionnaire. A total of 187 questionnaires were administered and a response rate of 60% (113 questionnaires were adequately filled and returned) was achieved. Descriptive and inferential statistics were utilised in analysing elicited data.FindingsThe results from data analysis showed that, “failure to influence the decision-making process/multiple conflicting decision-making”, “unstable regulatory regime”, “lack of available, accessible and fit-for purpose data”, “inadequate public knowledge of legal issues” and “poor provision of information” were the top most five barriers to EIA implementation for construction projects in Nigeria. Also, the results from the research show a statistically significant degree of agreement on the rankings by the groups of key stakeholders in EIA concerning the barriers to EIA implementation for construction projects.Originality/valueThis paper contributed to more effective EIA studies by drawing attentions to barriers to EIA implementation for construction projects. An understanding of these barriers can help key stakeholders in the construction industry of developing countries such as Nigeria to facilitate development of methods required in reducing barriers to EIA implementation in the construction sector.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43155590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study investigates the determinants of job satisfaction amongst a specific group of migrant construction workers, who hold temporary work visas (TWVs) in New Zealand (NZ).Design/methodology/approachAn explanatory research approach was used to investigate the determinants of job satisfaction identified through the literature review. Data were collected through a structured survey administered to 200 Chinese migrants on TWVs (short stays) working on selected major projects in the Auckland region. Data analysis involved T-test and structural equation modelling (SEM) of 102 valid questionnaire responses.FindingsThe study highlights the importance of providing opportunities for knowledge advancement and career progression for migrant construction workers to improve their job satisfaction. The results found that Chinese migrant construction workers are generally satisfied with their jobs and would extend their stay if job opportunities are provided. The results confirm that remuneration and opportunities for knowledge advancement and career progression lead to increased job satisfaction, while loneliness decreases job satisfaction. The opportunities for knowledge advancement and career progression triggered more satisfaction than remuneration.Originality/valueThe research result provides a useful knowledge base for understanding the determinants of job satisfaction amongst Chinese migrant construction workers with TWVs. These findings have implications for employment management practices within the construction industry and could enhance immigration information policies and other recruitment agencies' approaches to sourcing overseas workers for the NZ construction industry.","PeriodicalId":46426,"journal":{"name":"Built Environment Project and Asset Management","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48704519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three pillars of sustainable construction objectives, namely, social, environmental and economic, should be integrated into megaproject risk management to ensure long-term success. A risk assessment method, Risk Assessment Method for Sustainable Construction Objectives in Megaprojects (RAMSCOM), was developed for this purpose.Design/methodology/approachRAMSCOM was developed based on the latest concepts and identifying relevant and critical sustainability objectives and risks through an extensive literature review. Analytical Hierarchy Process (AHP) and Cross-Impact Analysis (CIA) were used to determine and quantify the threats regarding the importance of the sustainability objectives. The applicability of RAMSCOM was demonstrated on a real megaproject.FindingsThe findings revealed that sustainability risk assessment requires integration of economic, environmental, social objectives and analysis of cross-impacts of risk factors. Visualization of interrelated threats, vulnerabilities and objectives has a potential to support risk mitigation decisions to achieve sustainability goals.Research limitations/implicationsThe method has been developed based on the findings from a detailed literature survey on sustainability objectives and risks. RAMSCOM was tested on a single project with the assistance of three experts' views. Findings from the case project cannot be directly generalised for various megaprojects considering the unique nature of megaprojects.Practical implicationsDecision-makers can use RAMSCOM to assess sustainability risks in megaprojects and develop risk management plans for the most vulnerable and important sustainable objectives in a visual and quantified approach to ensure megaproject's sustainability in the long-term.Originality/valueThe theoretical contribution is a novel risk assessment method that integrates all dimensions of sustainability and quantifies the vulnerability of sustainability objectives considering their priorities, interrelations and risks.

The need to enhance sustainable construction with the adoption of Internet of Things in this sector cannot be overemphasized. However, the real-world applications of Internet of Things in smart buildings remain relatively unexplored in the AEC sector due to several issues related to deployment and energy-saving potentials. Given these challenges, this paper proposes to identify the present state of development and research in Internet of Things and smart buildings, identify Internet of Things clusters and applications in smart buildings.Design/methodology/approachBibliometric analyses of papers from 2010 to 2023 using the Scopus database and scientometric evaluations using the VosViewer software were undertaken. The proper search keyword was identified by using the phrases “ Internet of Things” and “Smart Building”. A total of 1158 documents in all, written by 3540 different writers, representing 2285 different institutions from 97 different countries were looked at. A metasynthesis was conducted and a system of Internet of Things applications in a smart building is illustrated.FindingsThe development of IoT and Smart Buildings is done in two phases: initiation (2010–2012) and development phase (2013–2023). The IoT clusters comprised Internet of things, energy efficiency, intelligent buildings, smart buildings and automation; while the most commonly used applications were analysed and established. The study also determined the productive journals, documents, authors and countries.Research limitations/implicationsDocuments published in the Scopus database from 2010 to 2023 were considered for the bibliometric analysis. Journal articles, conference papers, reviews, books and book chapters written in English language represent the inclusion criteria, while articles in press, conference reviews, letters, editorials, undefined sources and all medical and health publications were excluded.Practical implicationsThe results of this study will be used by construction stakeholders and policymakers to identify key themes and applications in IoT-enabled smart buildings and to guide future research in the policymaking process of asset management.Originality/valueThe study utilised bibliometric analysis, scientometrics and metasynthesis to investigate Internet of things applications in smart buildings.

Data were obtained from construction professionals including architects, builders, engineers and quantity surveyors. Retrieved data were analyzed using several statistical tools such as percentages, frequencies, mean item scores and exploratory factor analyses.FindingsBased on the mean item score ranking results, the top five significant benefits of adopting DTs were increased operational efficiency, increased productivity, increased speed of executing tasks, seamless working methodology and accurate documentation of data. Findings from the factor analysis revealed six clusters of benefits namely an improved framework for operations, improved innovativeness, improved safety practices, increased competitive edge, greater accuracy and increased productivity.Practical implicationsThis study expands on the existing discussions surrounding the digital transformation of the construction sector in developing countries, particularly in Nigeria, a region where the awareness and implementation of smart and innovative technologies are still at an infant stage.Originality/valueAlthough several studies on the benefits of adopting DTs in the construction industry of developing countries exist, very few have been conducted in the Nigerian context.
