Therefore, using data obtained from construction sites on a national highway in India, the major factors that contribute to the occurrence of accidents were explored in this study and various strategic and operational interventions that could be implemented to improve safety in road construction were established. A survey was conducted among the relevant stakeholders to collect both quantitative and qualitative data. Inferential statistical methods, including ordinal regression modelling, were used to analyse quantitative data and narrative and interpretive methods were used to analyse qualitative data. Based on the results, it was found that several factors, related to four important aspects, contribute significantly to the occurrence of accidents, including site conditions, traffic conditions, behaviour and attitude of construction workers, and information and training. It was established that operational interventions, such as the installation of early warning systems, mandatory use of safety equipment and gear, and signage and control at road construction sites can reduce accidents significantly. In addition, strategic interventions, such as implementing a specific road construction safety policy, creating awareness among the stakeholders and including the cost of health and safety in the project cost are vital. However, it was found that operational interventions are more influential than strategic interventions in the context of safety on road construction sites.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"22 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89530918","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, the functional decent work agenda matrix can potentially be utilised in place of the non-existent construction labour productivity performance monitoring tools. Hence, this study aims to determine significant decent work objectives for monitoring construction workers' productivity performance and also to examine demographic-related statistically significant differences. Given the exploratory nature of the study, a positivist paradigm was utilised for data collection and analysis owing to the aim of revealing relationships between construction workers' productivity performance and decent work objectives. Adequate earnings, productive work and environmental context were the most significant objectives while all other objectives were significant towards monitoring construction workers' productivity performance. Demographically targeted interventions include the need for adequate remuneration according to different generations and designations of workers, work-life balance for various designations and educational levels, improving the stability of employment, enhancing social security and improving training and awareness of environmental sustainability for workers of various designations. This study did not consider skilled construction workers' views as this was exploratory. Significant decent work objectives can be utilised to monitor construction workers' productivity performance, thereby improving both workers' welfare and productivity.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"47 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91200259","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}

Nevertheless, the uptake and use of GBs amongst most stakeholders in Africa are still on the low. Despite the plethora of studies on the economic benefits of green building, there is a dearth in studying the benefits in Africa. Within these economies, the presence of market restrictions, socio-cultural and political factors may mitigate against these benefits. This study seeks to unearth the economic benefits of GBs within the context of a sub-Saharan African country, Ghana. By adopting a quantitative research approach, a comprehensive literature review was first conducted. This was followed by the use of a questionnaire survey. A structured questionnaire was issued to building consultants in Ghana to elicit their perspectives on the economic gains of GBs. Mean scores, Wilcoxon signed-rank test and Kruskal-Wallis H test were respectively used to rank and assess the level of agreements amongst the various consultants on the economic benefits. Five economic benefits were identified from the study. This includes savings in energy, lower lifetime cost, lower operational cost, increased work productivity and \"transforms the construction industry\". The findings show that most of the economic benefits identified from literature cannot be realised in the study region, including \"high return on investment\" and \"increase in building value\". Consequently, building energy cost seems to play a crucial role in pushing the demand for the GB within the study milieu. The study provides a contextual understanding of economic benefits, useful to construction clients, property owners, real estate investors, consultants and the research environment. The findings are useful in providing market enablers to enhance a large-scale uptake of green construction. It is recommended that the provision of GBs should not be limited to only its impact on the environment and sustainability but also affordability concerns. This study provides a unique contextual perspective on the economic benefit of GB in a sub-Saharan African country.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"63 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89598288","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}

Given its nature as an industry-driven concept and system, this is universally accepted in industry as a tool to solve practical problems with a view to achieving an integrated enterprise information system. However, a developing country like Nigeria still faces a lot of hurdles in managing its construction supply chain. The aim of this study is to investigate the factors affecting the successful implementation of enterprise resource planning (ERP) systems in the Nigerian construction industry. After a literature search, expert input via the Delphi technique, the study identified four main factors and 21 sub-factors. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was used to prioritise the factors and to identify the relationship that exists between the factors. The findings revealed that the key factors affecting the implementation of ERP systems are \"A lot of security concerns\" (T7), \"The management of ERP projects is too complex\" (P5) and \"The inability to align the ERP solution with the business plans of the organisation\" (P2). This study recommends that the findings of this work will help both local and international practitioners alike.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"180 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77312445","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}

Asiedu, Faisal Iddris","doi":"10.21315/jcdc2022.27.1.1","DOIUrl":"https://doi.org/10.21315/jcdc2022.27.1.1","url":null,"abstract":"This article explores the link between value co-creation, a project's success and satisfaction of the project's stakeholders. It also looks at how a project's success mediates the relationship between value co-creation and the stakeholder's satisfaction. A quantitative approach with an online questionnaire was used to collect data from a sample of 140 respondents in Ghana. Data were analysed using partial least square structural equation modelling (PLS-SEM). The results show that value co-creation positively and significantly relates to a project's success and stakeholder satisfaction. The findings also support that a project's success mediates the impact of value co-creation on the stakeholders' satisfaction. Based on these findings, we suggest that project managers be critical about the type of value co-creation strategy they will use to engage project stakeholders. This would apply when adopting the value co-creation approach to manage their projects while not sacrificing success. This study focused on the impact of value co-creation on a project's success and its stakeholder's satisfaction. The survey data were collected only to evaluate the overall effect of value-co-creation on the success and stakeholder's satisfaction of projects. The adoption and implementation of value co-creation in project management may enhance the definition of the project's scope, performance specifications and other criteria used to measure the success of a project, to meet the needs of stakeholders. By empirically presenting a project's success as a key mediator in shaping the effect of adopting value co-creation in project management on the stakeholder's satisfaction, this study laid a foundation for further theoretical explorations involving value co-creation in project management.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"272 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87083456","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 case study project was scheduled using both CPM and LSM tools and the results were compared in terms of estimated total duration and resource cost. The results showed that LSM produced a saving of 10 days in total duration and 20.07% in estimated resource cost over CPM. LSM also proved to be the better tool in terms of other schedule attributes like resource assignment, levelling, visualisation, etc., for alignment-based projects. LSM can be highly efficient for scheduling different types of repetitive construction and offers benefits like better workflow and continuous resource usage.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"31 2 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89743235","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}

Purposeful sampling technique was used to select the study sample from the total population. A total of 93 questionnaires were administered, out of these, 61 were duly completed and used for the study. The study adopted the ranking model and mean rating in analysing the data. Conflict of interest and lack of trust were the major determinants of opportunism manifesting in deliberate underbidding by private sectors and delays in disbursement of approved project funds. Strategic behaviours can effectively be prevented and mitigated by developing trust among stakeholder and use of contract structure. The study suggests structuring of contracts such that opportunism is avoided or reduced to acceptable level, building of trust among stakeholders and building an environment with adequate incentives to penalise collusion attempts as strategies for preventing and mitigating opportunism in PPP housing projects.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"46 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74171143","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}

Integrated Project Delivery (IPD) is an approach that removes the gap between the planning and construction stages of a project. Various barriers to implementation exist within the construction industry, and these can be resolved by effective solutions. Identifying and classifying these solutions is considered essential for successful project delivery. In this context, this study aims to illustrate and classify the solutions that have been proposed since the introduction of IPD as a new approach for the implementation of construction projects. In this study, a metasynthesis approach has been used as a qualitative method, and pattern and descriptive coding and analysis have been used to analyze the data. The solutions analyzed in the meta-synthesis suggest that all stakeholders—including designers, construction engineers, construction team members, and operation and maintenance team members—each have the same responsibility to improve IPD and meet the project goals. This study is significant because it suggests important resolutions to the barriers to IPD implementation and may help construction industry stakeholders better facilitate IPD and enhance clauses of their contracts.","PeriodicalId":51876,"journal":{"name":"Journal of Construction in Developing Countries","volume":"276 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77574470","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}
