Previous research works on the integration of e-Procurement technologies in the construction process in Nigeria showed that it has been slow and low. However, there are few empirical studies on the duration for which it has permeated the construction industry, the actual proponents and the metrics that can engender successful integration of e-Procurement technologies, applications, and tools in the construction procurement process, especially in a developing country like Nigeria. The study was aimed at evaluating the critical success factors (CSFs) for e-Procurement adoption in the Nigerian construction industry. The study was carried out in the six geo-political zones in Nigeria using a survey research design. Construction stakeholders were selected using purposive and random sampling techniques. A total of 1092 questionnaires were retrieved in this study, but the data of 759 actual users of e-Procurement systems were analyzed in this study using descriptive statistics and principal component analysis (PCA). An assessment of the duration users have been participating in the e-Procurement environment revealed that most Quantity Surveyors have been exposed to the use of e-Procurement technologies for over 10 years. A large proportion of the construction stakeholders picked up the use of the technology within the last 5 years. Further analysis showed that contracting firms have the largest participation in the use of e-Procurement systems. The study also revealed that construction stakeholders perceived the availability of reliable, affordable, and fast Internet services as the most critical success factor for the adoption of e-Procurement technologies. The critical success factors (CSFs) were further classified into management support for physical infrastructure, and human factors and characteristics of the technology. The study showed that these critical success factors (CSFs) are crucial for the adoption of e-Procurement systems in the Nigerian construction industry. The study recommended that there is still a need for increased awareness of the e-Procurement tools and technologies and the benefits that are accrued from their use among public sector construction participants. This will in turn influence the provision of the required information and communication technology (ICT) physical infrastructure and formulation of appropriate policies and standards for successful e-Procurement integration in the Nigerian construction industry.

Purpose: The aim of this paper is to assess the behavioural factors that influence professionals' intention to adopt green construction based on the theory of planned behaviour (TPB).Design/methodology/approach: The study adopted a quantitative research design with the use of online questionnaires to elicit information from construction professionals in South Africa. Descriptive statistics of frequencies, mean and standard deviation were used to analyse the data obtained from the survey. Linear regression was also used to assess the effect of behavioural factors on professionals' intention to adopt green construction.Findings: The results showed that attitude and perceived behavioural control (PBC) have a significant effect on the intention to adopt green construction. These were significant at p < 0.05, having p-values of 0.000 and 0.015 respectively. The study also found that there was a positive disposition towards green construction, particularly with regards to insisting on green construction. This had a mean value of 3.99. There was also a high perception of succeeding in the execution of green projects with mean score of 3.76.Practical implications: The practical implication of the findings is that adoption of green construction in South Africa is majorly based on the positive attitude of stakeholders towards green construction and also the PBC or the perceived ease of executing green construction. However, these factors are not sufficient to generate long term commitment for green transformation among a critical mass of stakeholders in the South African construction industry. Hence, there is a need for focus on subjective norms (pressure) particularly from the government, to encourage the widespread adoption of green construction in South Africa.Originality/value: Findings present one of the pioneering efforts to empirically validate the influence of behavioural factors on the intention to adopt green construction in South Africa and the outcomes can provide policy directions and baseline data for further research.

The construction site provides an unfriendly working conditions, exposing workers to one of the harshest environments at a workplace. In this dataset, a structured questionnaire was design directed to thirty-five (35) craftsmen selected through a purposive sampling technique on various construction sites in one of the most populous cities in sub-Saharan Africa. The set of descriptive statistics is presented with tables, stacked bar chats and pie charts. Common occupational health conditions affecting the cardiovascular, respiratory and musculoskeletal systems of craftsmen on construction sites were identified. The effects of occupational health hazards on craftsmen and on construction project performance can be determined when the data is analyzed. Moreover, contractors' commitment to occupational health and safety (OHS) can be obtained from the analysis of the survey data.

Purpose: Industry 5.0 provides significant social, environmental and economic benefits over previous industrial revolutions. However, research in the field of industry 5.0 is still at a very nascent stage. Little is known about research trends in the field and its applications in specific sectors as construction which have relatively low sustainability index. Hence, this study aims to explore research trends in industry 5.0 and its applications in the construction industry.Design/methodology/approach: The study adopted a bibliometric analysis with the use of the vosviewer. The main search words used in the study were “Industry 5.0”, “Society 5.0” AND “Fifth Industrial Revolution”. Initial extracted papers with these keywords were 1036. After refining based on language, document type, key words and timeframe, a total of 188 papers were found suitable for the analysis.Findings: The most impactful research on Industry 5.0 to date was from the United States, Australia and Sweden while the journal sustainability was found to be the highest document source on Industry 5.0. The application areas of industry 5.0 in the construction industry include health and safety, collaborative working, waste management, measurement of environmental features (indoor air quality, atmospheric pressure, noise, humidity and temperature) and forecasting of environmental, social or financial outcomes.Research limitations/implications: The study used review based papers which form the bulk of the existing research on industry 5.0. This limits understanding of the practical applications, benefits and challenges associated with the use of industry 5.0.Originality/value: This work contributes to the theory and practice of industry 5.0 by providing baseline data for future research directions on industry 5.0. The work specifically highlights the application areas of industry 5.0 in the construction industry and also indicates the need for questionnaire, interviews or case study based research to enhance understanding of the practical applications of industry 5.0.

Purpose: Sustainability transformation in the construction industry is vital for the attainment of sustainable development goals. While conventional construction has been at the expense of social and economic sustainability, sustainable construction can enhance environmental, social and economic outcomes for the construction industry and society at large. However, the industry struggles with new initiates because its stakeholders are products of unique institutions which shape their decisions and intentions to adopt new practices. This study assessed the institutional pressures that influence the adoption of sustainable construction to enhance our understanding of other factors that can promote and accelerate the adoption of sustainable construction.Design/methodology/approach: The study adopted a quantitative research design with the use of online questionnaires to elicit information from construction professionals in South Africa. Descriptive statistics of frequencies, mean and standard deviation were used to analyse the data obtained from the survey. Linear regression was also used to assess the influence of institutional pressures on the adoption of sustainable construction.Findings: Mimetic pressures were found to have a significant influence on the adoption of sustainable construction. The decision to adopt sustainable construction was based on the sustainability actions of industry leaders (mimetic pressure). Normative and coercive pressures had no significant influence on the adoption of sustainable construction.Practical implications: Mimetic pressure from competitors and normative pressures is already exerting some pressure on stakeholders to adopt sustainable construction. However, there cannot be a long-term commitment that will yield the needed sustainability transformations without additional normative pressure from learned societies and coercive pressure from the government. As one of the pioneering works from the global south, this study provides empirical validations of the influence of institutional pressures on the adoption of sustainable construction. It also enhances understanding of how institutional pressures from the social context can promote and accelerate the adoption of sustainable construction.Originality/value: The findings present one of the pioneering efforts to empirically validate the influence of institutional pressures on the adoption of sustainable construction.
