The built environment contributes to environmental concerns, including carbon emissions, with traditional construction materials being problematic. Adopting sustainable construction materials (SCMs) is envisaged; however, barriers exist. Hence, this study sought to determine significant barriers to adopting SCMs in Zimbabwe.

An online questionnaire survey of construction professionals in consultancy firms and semi-structured interviews with key informants in Zimbabwe and Africa were instituted. Mean score analysis, normalisation values and exploratory factor analysis were quantitatively used to determine significant barriers. Content analysis of qualitative data from key informants was used to triangulate the findings.

From the normalisation (with values > 0.90) and thematic analysis, a lack of incentives, training and government support were exposed as the most critical barriers. The factor analysis revealed seven significant components: governmental policy, finance and research support-related; sustainable construction material supply chain-related; green building policy and capacitation-related; change and trust-related; cost and complexity-related; project execution and investment-related and awareness and demand-related.

The insights of construction professionals from construction companies were not solicited. However, construction consultancy professionals who have a more significant influence on adopting SCMs were included. The government and clients are most critical in promoting the adoption of SCMs through enacting relevant policies and establishing buy-in.

According to the authors’ knowledge, this is the first study to determine barriers to adopting SCMs through the contribution of key informants from various countries within the African continent.

Despite “decent work” being pertinent, as situated in the International Labour Organisation's “Decent Work Agenda”, one of its substantive elements on the need for safe work environments remains a concern for semi-skilled construction workers. Evidently, sustainability learning objectives within this element must be identified and implemented as a remedy. Therefore, the aim of the reported study was to reveal sustainability learning objectives that are significant towards attaining safe work environments, through also assessing statistically significant differences due to demographic variables.

The design of this research followed a quantitative questionnaire survey strategy to obtain insights from semi-skilled workers and site/project managers in Zimbabwe.

Knowledge of relevant prevention strategies to foster positive physical and mental well-being in the workplace was considered the most critical sustainability learning objective. Semi-skilled workers revealed the most interest in objectives that affected their socio-economic beings while site/project managers preferred those that had more economic value to the organisations they work for. Educational levels are also critical when instituting any training interventions.

The absence of a database for semi-skilled workers was a limitation towards achieving the practical significance of the findings. Due to semi-skilled workers significantly contributing to unsafe work environments, structured on-the-job training schemes that are sufficiently planned, monitored and controlled are recommended.

The determination of sustainability learning objectives for construction semi-skilled workers, through on-the-job training schemes, will contribute to the improvement of safe work environments.

While operational factors reduce construction workers' productivity in Zimbabwe, the impact of the people-centred management aspects has not been empirically interrogated as a remedy. This article reports on a study that sought to determine significant people-centred management aspects that lead to improved labour productivity and assesses the existence of statistically significant differences due to the demographic variables of respondents. Demographic-specific strategies that enhance construction “workers” productivity were revealed.

The survey research design using a self-administered questionnaire was deployed to collect the primary data. The design followed a positivist paradigm to evaluate objectively how people-centred management affects construction workers' productivity. The statistical data were descriptively and inferentially analysed.

People-centred management was determined to be significant in improving construction workers' productivity, with the most significant aspect being the building of employee confidence in related approaches. Designations and educational levels mostly indicated a statistically significant difference in several aspects that included the adoption of a functional reward culture for workers and training on people-centred principles. Training on-site management and construction workers in people-centred management and its application are crucial to improving construction workers' productivity.

Construction companies should drastically improve their concern for people while they sustain a high concern for production within their construction sites. Although several factors affect construction workers' productivity, this study determined that management-related factors and people-centred management were significant towards influencing low productivity in Zimbabwe.

The study determined people-centred management and demographic-specific interventions as being able to improve construction workers' productivity in Zimbabwe.

Increased construction risk due to the complexity and numerous construction performance challenges requires improved construction project managers’ competence. However, contextual interrogation of these competencies is limited. This paper aims to report on a study that sought to determine the expected competencies of construction project managers and assesses the existence of statistically significant differences due to gender, designation and educational levels of respondents.

A quantitative research design was instituted through the administration of a questionnaire survey on Project Managers, Architects, Engineers and Quantity surveyors working for consultants and contractors’ organizations. Descriptive and inferential statistics analysed significant differences due to demographic variables. Factor analysis was also used to reveal interrelated significant sets of competencies expected of construction project managers.

Factor analysis determined 11 significant components with the highest-ranked components comprising organizational savvy and experience in managing project constraints. The univariate analysis determining effective communication, leadership and good team-building skills as being the three most critical expected competencies. Significant differences due to educational levels were established, with shortcomings existing in those with Diplomas.

The higher education institutions need to establish curricula designs that align with the competency expectations. Mentorship programmes within construction organizations can also be significant in bridging the existing competence gap. However, due to the exploratory nature of the study, the insights of clients were not considered.

The study determined competencies for construction project managers and demographic-specific interventions.

Achieving sustainable construction is immensely challenging in developing economies due to their inadequate technical support system(s) (TSS). Hence, this article develops a TSS framework for sustainable construction indicators for Zimbabwe, a developing country.

A post-positivist philosophical stance and deductive reasoning were adopted to test pertinent theory. Construction professionals in consultancy, construction companies, government bodies and academic institutions participated in an online questionnaire survey. Primary data was analysed using a reliability test, Shapiro Wilks test, Kruskal–Wallis H test, mean score ranking, normalisation value, factor analysis and fuzzy synthetic evaluation (FSE).

FSE revealed a framework with six critical technical support subgroups, in order of importance viz: innovation for construction sustainability; adequate sustainability expenditure and skills training support; adequate project economic assessment and governance support; adequate circularity and environmental technical support; climate change literacy and supplier assessment support; and adequate decent work support. Existing sustainable construction initiatives can be buttressed by strengthening the six identified TSS through related policy initiatives.

The framework developed constitutes an innovative TSS for Zimbabwe to achieve sustainable construction.

Construction professionals' literacy incapacity exacerbates their vulnerability to climate change hazards on construction projects. Therefore, this study sought to determine climate change literacy objectives for Zimbabwean construction professionals. Climate change-literate construction professionals can significantly strengthen resilience and adaptive capability within the built environment.

The positivist approach employed a cross-sectional questionnaire survey strategy to collect quantitative data from construction professionals (Architects, Civil/Structural engineers, Project managers and Quantity surveyors) working in 280 registered consultancy and construction firms in Zimbabwe. The data were analysed using mean scores, normalisation, Kruskall–Wallis tests and factor analysis.

The respondents’ perceptions of the most critical climate change literacy objectives included knowledge of sustainable material utility, designing for resilient structures and understanding how climate change affects workers' physical and mental well-being. Generally, consensus on the nature of climate literacy objectives was evident. The factor analysis determined three components: stakeholder and climate information-related interventions, carbon and environmental footprint-related literacy and climate systems and indigenous knowledge-related literacy. Construction professionals can interpret climate change information through the determined objectives, contribute to reducing carbon and environmental footprint and improve project outcomes.

A limitation was that a quantitative method was only employed; a concurrent qualitative inquiry could have mined more diverse views. Professional bodies and tertiary institutions can design climate change programmes based on the determined climate change literacy objectives for construction professionals.

The study determined climate change literacy objectives for construction professionals in Zimbabwe to enable them to respond to climate change hazards.

Increased waste during projects execution has led to time and cost overruns within the Zimbabwean construction projects industry. However, contextual barriers to lean construction implementation are yet to be established for derivation of effective remedies. The purpose of this paper is to report on a study that sought to determine barriers to lean construction implementation and assess the existence of statistically significant differences because of gender, designation and educational levels of respondents.

A questionnaire survey was administered on construction professionals for the collection of quantitative data. Factor analysis was used to reveal interrelated significant sets of barriers to lean construction implementation. Non-parametric statistical methods were also used to determine significant differences because of demographic variables.

Integration- and performance-related, human capital management–related, quality management–related barriers were determined as the highest-ranked of the nine significant components. Significant differences because of gender, designation and educational levels were non-existent for aggregated barriers, generally indicating consensus on the barriers. However, individual barriers showed inadequacies in management requirements for lean construction implementation from architects and those with diplomas and degrees.

The determination of barriers establishes the knowledge for construction policy evaluation for enhanced performance of the construction industry. However, because of the exploratory nature of this study, the insights of clients were not considered.

Context-specific barriers to lean construction implementation were determined for consequent construction policy improvements in the construction industry.

The purpose of this study was to investigate the perceptions of construction professionals relative to factors that affect the delivery of optimum health and safety (H&S) on construction projects during the COVID-19 pandemic.

The study adopted a quantitative design which entailed the distribution of a web-based questionnaire among construction professionals, namely, architects, construction/project managers, engineers, H&S managers and quantity surveyors working for contractors and construction consultants in Zimbabwe. The data were analysed with descriptive and inferential statistics. Factor analysis was used to reveal interrelated significant sets of factors affecting the delivery of optimum H&S.

Factor analysis revealed nine components/factors: change and innovation-related, monitoring and enforcement-related, production-related, access to information and health service-related, on-site facilities and welfare-related, risk assessment and mitigation-related, job security and funding-related, cost-related and COVID-19 risk perception-related factors as the significant factors affecting the delivery of optimum H&S during the COVID-19 pandemic in Zimbabwe.

The results highlighted the need for social dialogue among construction stakeholders to support initiatives that will enhance the delivery of H&S on construction projects. Construction stakeholders may find the results useful in highlighting the areas that need improvement to protect workers’ H&S during the pandemic. However, the small sample limits the generalisability of the results to construction sectors in other regions.

The study investigated factors affecting the delivery of optimum H&S during the COVID-19 to inform interventions to enhance H&S.

Persisting construction performance shortcomings in the Saudi Arabian construction industry requires engendering project management competencies in construction professionals’ roles and responsibilities. The purpose of this study was to determine significant construction project management competencies for Saudi Arabian construction professionals.

A cross-sectional questionnaire survey used project managers’ competencies from the literature. Construction professionals participated in the survey. Normalisation was used to determine the critical individual competencies. Statistically significant differences due to designations and organisations were analysed. Factor analysis revealed the relationships among significant competencies.

The most critical individual competencies included communication, team building and leadership skills. However, Project managers and all other construction professionals had statistically significant differences in insights on some of the critical competencies. The results revealed seven components: behaviour and attitude-related competencies; fundamental project management-related competencies; pro-active, knowledge and creativity-related competencies; political and organisational-related competencies; stakeholder management and experience-related competencies; management-related competencies; and confidence, commitment and negotiation-related competencies.

Evidently, inculcating project management competencies is essential for construction professionals to enhance project performance. The failure to get insights from the National Project Management Office officials was a limitation; however, views from construction professionals were sufficient as they are the most affected stakeholders.

The study determined project management competencies necessary for Saudi Arabian construction professionals to improve their project delivery performance.

This study aims to analyze the critical factors affecting workplace well-being at construction sites across countries with different income levels. Accordingly, this study’s objectives are to identify: critical factors affecting workplace well-being at construction sites in low-, lower-middle-, upper-middle- and high-income countries, overlapping critical factors across countries with different income levels and agreements on the critical factors across countries with different income levels.

This study identified 19 factors affecting workplace well-being using a systematic literature review and interviews with construction industry professionals. Subsequently, the factors were inserted into a questionnaire survey and distributed among construction industry professionals across Yemen, Zimbabwe, Malaysia and Saudi Arabia, receiving 110, 169, 335 and 193 responses. The collected data were analyzed using descriptive and inferential statistics, including mean, normalized value, overlap analysis and agreement analysis.

This study identified 16 critical factors across all income levels. From those, 3 critical factors overlap across all countries (communication between workers, general safety and health monitoring and timeline of salary payment). Also, 3 critical factors (salary package, working environment and working hours) overlap across low-, low-middle and upper-middle-income countries, and 1 critical factor (project leadership) overlaps across low-middle, upper-middle and high-income countries. The agreements are inclined to be compatible between low- and low-middle-income, and between low- and high-income countries. However, agreements are incompatible across the remaining countries.

This study can serve as a standard for maintaining satisfactory workplace well-being at construction sites.

To the best of the authors’ knowledge, this study is the first attempt to analyze factors affecting workplace well-being at construction sites across countries with different income levels.
