E-procurement has the advantage of improving the overall performance of construction project delivery. The purose of this study is to uncover the factors influencing e-procurement acceptance in the public sector of Ghana’s construction industry (GCI). Using an extended unified theory of acceptance and use of technology (UTAUT 2), variables that promote the acceptance of e-procurement in GCI were explored.

Data was collected using a mixed method strategy. In the first stage, a semi-structured interview was used to collect, assess and optimize the UTAUT2 model. Thematic analysis was used on the qualitative data, leading to modification of the proposed UTAUT2 model. The study subsequently used a questionnaire survey using the extended UTAUT2 model. Survey data was analyzed using structural equation modelling (SEM), leading to the identification and validation of factors that facilitate e-procurement acceptance in Ghanaian construction as well as the impact of these factors.

The findings of the study reveal that five independent constructs of the proposed UTAUT2 model significantly affects the behavioural intention of practitioners to accept and use e-procurement in the construction industry in Ghana.

The study will be of utility to government agencies, contracting organizations and other construction stakeholders in developing policy and programmes to support e-procurement acceptance within the sector.

This is a new extended UTAUT2 model that is applicable to technology acceptance within the public sector in sub-Saharan Africa.

This paper aims to investigate the Occupational Safety and Health (OSH) management practices of construction companies in South Korea to ascertain specific components and practices that need improvement for successful OSH performance.

A quantitative research strategy was adopted. A close-ended questionnaire survey covering 45 OSH management practices was sent to 324 contractors; 108 responses were gathered, representing a response rate of 33.3%. Data were analysed using simple descriptive statistics (frequencies and percentages) and Pearson’s chi-square test.

The findings revealed that there is a moderate level of implementation of OSH management practices among construction firms in South Korea. However, there is a significant disparity in terms of implementation between large enterprises on the one hand and small to medium enterprises on the other. Furthermore, a few of the business characteristics (i.e. the size of companies and certification to OHSAS 18001) were closely associated with the extent of the implementation of OSH management practices.

This research uncovers the OSH management practices that are poorly implemented and lays the foundation for appropriate measures to improve OSH in South Korean construction companies. It suggests an effective strategy for communicating health and safety issues to workers, training safety managers, reviewing risk assessments, reviewing the health and safety plan, incentivising workers by rewarding good behaviour and having a penal mechanism for employees not adhering to the rules.

The study provides insights into an under-investigated South Korean construction industry topic. It offers additional insight into state-of-the-art health and safety management practices in the construction industry in South Korea. Furthermore, it establishes which components of OSH management practice require improvement in the Korean context. This is also one of the few studies in OSH which establishes the association between the construction business characteristics and OSH management in the South Korean construction domain.

The uptake of Design for Safety (DfS) practices in developing countries like Ghana has been limited. This study aims to provide an in-depth understanding of the barriers across regulatory, organizational, cultural and educational dimensions that restrict DfS assimilation in the Ghanaian construction sector. Identifying the key impediments can inform policy initiatives and industry efforts to facilitate safer construction.

A postpositive philosophy underpinned the quantitative research. Multi-stage research was used. A comprehensive questionnaire survey was designed and given to six industry experts to assess clarity, relevance and effectiveness after a thorough literature review. In all, 164 professionals were reached to take part in the study using purposive sampling and consequently snowballing. “Variables” were ranked using mean score ranking and normalization techniques; exploratory factor analysis was then used to group variables into clusters.

Emergent findings revealed four distinct clusters of challenges; Design Process and Communication Challenges; Regulatory and Expertise Limitations; Planning and Education Constraints; and Attitudinal and Perception Barriers. These findings help identify targeted solutions to overcome barriers including developing robust regulatory frameworks, promoting collaboration among stakeholders and cultivating a positive safety culture.

This study provides new insights into the integration of DfS in the context of the developing construction industry in Ghana. This study expands the knowledge base to drive further research in enhancing construction safety in developing countries. Practical recommendations for overcoming these challenges are proposed.
