Purpose 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. Design/methodology/approach 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. Findings 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. Research limitations/implications 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. Originality/value Context-specific barriers to lean construction implementation were determined for consequent construction policy improvements in the construction industry.

Purpose 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. Design/methodology/approach 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. Findings 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. Research limitations/implications 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. Originality/value The study investigated factors affecting the delivery of optimum H&S during the COVID-19 to inform interventions to enhance H&S.

Construction labour productivity is declining, due to shortcomings in the Decent Work Agenda. This research seeks to determine decent working conditions that could improve the productivity of skilled and semi-skilled workers on construction sites in Zimbabwe. A quantitative research approach enabled a self-administered questionnaire survey among site management and workers from selected trades. The randomly selected respondents work for construction companies affiliated with the Construction Industry Federation of Zimbabwe database. The companies are based in Harare, Bulawayo, and Shurugwi. In addition, thirteen building project sites in the study area were purposively selected through the National Social Security Authority register.The results indicate that adequate work-related health and safety conditions and facilities were identified through ranking as the most significant decent work conditions under which improved labour productivity can be achieved. It is also notable that all the decent working conditions Sleutelwoorde: Arbeidsproduktiwiteit, konstruksie, voldoende werk, volhoubare ontwikkeling, werksomstandighede, Zimbabwe

PurposeWhile 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.Design/methodology/approachThe 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.FindingsPeople-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.Research limitations/implicationsConstruction 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.Originality/valueThe study determined people-centred management and demographic-specific interventions as being able to improve construction workers' productivity in Zimbabwe.

Purpose 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. Design/methodology/approach 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. Findings 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. Research limitations/implications 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. Originality/value The study determined competencies for construction project managers and demographic-specific interventions.
