However, the success of the Ghanaian public road project consultant selection phase has not received any attention, even though it is prone to corruption. The goal of this study is to identify the critical success factors (CSFs) that, from the standpoint of a developing country, affect the success of the Ghanaian public road consultant selection phase. Data on the degree to which key success criteria identified in literature have an impact on the success of the Ghanaian public road consultant selection phase from the viewpoints of 156 sector practitioners in Ghana were acquired using a self-administered questionnaire. After that, the relative importance index was used to analyze the data. According to the study, external environmental, project management, and procurement-related factors influence the success of the Ghanaian public road consultant selection phase. The government and organizations that administer public construction projects will now have a better grasp of the CSFs that affect the performance of the Ghanaian public road construction project consultant selection phase and be able to use them as a guide to improving the effective and efficient delivery of public road construction projects. In managing public road projects, the study's findings will be useful to both industry professionals and the Ghanaian government. The study is limited to the consultant selection phase of Ghanaian public road construction projects. \u0000Keywords: Critical success factors, construction, consultant selection phase, construction management, relative importance index.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141682483","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}

Gledson, David Greenwood","doi":"10.5130/ajceb.v24i1/2.8394","DOIUrl":"https://doi.org/10.5130/ajceb.v24i1/2.8394","url":null,"abstract":"Learning from past project failures presents opportunities for firms working within the construction sector to ‘build back wiser’ because, if lessons from these experiences are absorbed, they offer benefits such as mitigation against future failures, and enable the development of resilient project teams. However, instead of using sector-wide perspectives for organisational learning, Project-Based Organisation (PBOs) typically implement internal technological and strategic mechanisms in both learning and project management. Additionally, little attention is given to the institutional context within the sector. Hence, this study focuses on how learning within a PBO is influenced by the external environment by adopting an Institutional theory perspective. Via exploratory research, data were collected through semi-structured interviews with 19 UK construction industry professionals and then analysed using thematic analysis. Findings reveal that there exists an institutional field of learning within which PBOs operate based on interactions with their external environment. These include: regulatory pillar-related organisations – such as government bodies, and regulatory bodies (e.g., the Health and Safety Executive); Normative pillar-related organisations (professional bodies such as APM and CIOB), and; cultural-cognitive pillar-related organisations (such as peer PBOs, suppliers and the wider supply chain). The study contends that each of these pillars offer lessons for the sector. Findings further reveal that cross organisational learning is hampered mostly by competition and fragmentation. Hence, to ‘build back wiser’ it is important that the sector brings together the identified institutional field members to better learn from project-related failures. Thus, PBOs need to build better institutional networks by viewing other organisations within the institutional field as sources of knowledge and embracing collaboration instead of competition.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680969","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}

While IPD emphasizes team integration and process alignment to drive better outcomes, the lack of standardized benchmarks to evaluate its performance relative to traditional methods persists as a barrier. To bridge this gap, this study developed a practical, and unbiased Project Success Framework (PSF) for IPD on industrial projects. A mixed methods research approach including subject matter experts’ survey, research charrette, and validation survey was conducted to build and validate the PSF. In addition, this study proposed a machine learning (ML)-based application tool embedding PSF to enhance the practicality and applicability of PSF. The machine learning-based application tool was validated by comparing the results with the PSF suggested in this research. The PSF developed in this study allows researchers and practitioners to empirically evaluate the integrated project delivery's efficacy on key industrial project outcomes. In addition, it offers a method to compare project delivery methods across diverse projects, aiding organizations in precise selection using empirical evidence for optimal results. Moreover, this framework aids clients in crafting shared risk/reward models that foster successful outcomes by encouraging desirable behaviors.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.8,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680986","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}

Among the various forms of data, information from the mental database of stakeholders is considered the most important which can be accessed through stakeholder engagement using interviews. However, formal, and systematic process of interview and data analysis is required. Existing approaches used for systematically analysing qualitative data were based on grounded theory approach. In this study, we introduced a coding approach that is formulated based on the principles of thematic analysis, saliency analysis (an extension of thematic analysis) framework and case study approach, and key strengths of existing methods. This alternative or formulated approach is focused on (i) coding the data from all stakeholder groups, (ii) establishing causal relationships from causal attributions of stakeholders and transform the causal relationships into causal maps and (iii) establishing and maintain strong links between causal maps and data source using data source reference table and software. We then demonstrate an application of the coding approach in a study about cost performance of road infrastructure projects in Nigeria to analyse qualitative data collected from 16 semi-structured interviews.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138950747","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 aims to assess the performance of labour in construction by applying systematic work-based training components. A comprehensive study methodology was adopted through literature reviews and experts’ interviews/discussions, with problem-focused and action-oriented communication approaches to develop effective tools, systems and practices related to labour training elements and performance assessments within a framework. Through a new construction supervisory training programme, the developed practices were applied to 200-300 labourers working on 23 construction projects in Sri Lanka. The results show the detailed patterns of the significant changes in labour performance with the quantified values. Overall quantitative values indicate a nearly 60% increase in the performance of labour within six months of the training period compared to the starting point. A considerable level of performance improvement was reported in the soft skills (90%) and material handling abilities (70%) of labourers. A moderate level of performance improvement was identified in other competency elements related to the application of basic science/technology-related practices (55%), simple engineering/technology-related practices (44%), construction methods and technology (56%), green practices (36%) and fundamental management aspects (34%). The overall performance values of labourers employed in road/bridge projects were found that noticeably lower compared to the labourers who worked on other types of projects. The results further describe the well-improved theoretical knowledge and operational skills of the trained labourers, which has uplifted their job standards from working under close supervision to working under general supervision with some autonomy. Moreover, the study findings contribute to controlling the excessive inclination of local firms toward foreign labour by unlocking the potential barriers to expanding the local labour supply with lifelong learning and career benefits/opportunities for labourers. The findings will have a significant impact on how other developing nations and industries must manage their labour to obtain higher work efficiency in the foreseeable future.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011010","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}

Based on a questionnaire survey of workers in the province of West Java, it aims to test the view that informal workers are more vulnerable to job losses, wage cuts and the lack of social security safety net. Two research questions were posed. The first was to characterise the impact of the COVID preventative measures on their access to work, work hours, and income levels. The second objective was to examine the implementation of COVID-19 health and safety protocols at project sites and its impact on workers. A survey conducted in November and December 2020 in the province of West Java obtained 261 responses from 21 construction companies. Contingency table testing was carried out to test the hypothesis that the frequencies of occurrence in the formal and informal worker categories are independent of the frequencies in incomes and health and safety protocols. Contrary to job losses and wage cuts report in the literature, construction companies in West Java have resisted cutting the wages of informal workers and instead directed wage cuts to their higher paid formal workers. Compliance to COVID-19 health and safety protocols at project sites was reported to be high. This study makes unique contribution to the understanding of informal work in the construction industry and the impact of the recent pandemic on the incomes and workers’ welfare.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139011811","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}

Last Planner System (LPS) is one of such distinguished tools used by construction majors. Many research suggests that LPS plays a significant role in improving the collaboration among the project team members and the firm's organizational culture. This paper reports the intermediating effect of organizational culture on construction projects that implement the Last Planner System and also identifies the effect of LPS on the project's operational performance. Various survey items pertaining to each variable was identified and was validated through Content Validation. All the established items were then compiled into a questionnaire, and multiple data were collected from a variety of projects. The data were analyzed using bivariate correlation and multiple regression analysis. Additionally, the \"organizational culture assessment instrument\" was utilized to compare the organizational cultures of various construction sites. It was discovered that the Last Planner System had a positive but negligible relationship with the operational performance of the project, and the organizational culture. It was observed that all the projects implementing LPS had a balance culture. The contribution of this work is the knowledge that the implementation of the Last Planner System is not necessarily enhanced by culture to a great extent. However, it has a positive impact on both the operational performance of the project and the organizational culture.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010712","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}

The objective of this study is to discern the underlying rationale behind anti-corruption systems and ascertain their impact on the occurrence of corruption in the context of project planning and execution (PPE) within Nigeria. The research formulated a theoretical framework that classified the anti-corruption measures into three distinct systems and elucidated their underlying rationale. The model postulates that anti-corruption measures that exhibit a significant influence on corruption in the realm of PPE are those that prioritise the enhancement of reputation and remuneration. The hypotheses were extracted from the model and subjected to testing through the utilisation of multiple linear regression (MLR). The efficacy of all the classifications of anti-corruption systems was determined to be inadequate in mitigating the occurrence of bribery, fraud, and substandard documentation. The empirical findings indicate that the expansion of information access exhibits a robust logical framework and exerts a substantial influence on the prevalence of corruption within the realm of PPE in Nigeria. The results of this study propose a potential strategy for an anti-graft campaign and provide insights into the importance of consolidation.","PeriodicalId":51729,"journal":{"name":"Construction Economics and Building","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139010882","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}
