Nevertheless, 70-80 percent of the SME contractors have been failing within the first five years, mainly because of low productivity, which affects the economy negatively and ends up causing job losses. It has been observed that poor on-site labour productivity often leads to profit losses, inefficiency in utilisation of resources, and lack of competitiveness. Therefore, in this study, effective on-site labour productivity modalities that can be adopted by SME contractors to enhance sustainable construction project delivery are proposed. In an effort to improve SME contractor’s on-site labour productivity, this study investigates perceptions of SME contractors regarding on-site labour productivity, on-site labour productivity challenges among SME contractors, factors in enhancing effective on-site labour productivity, and effective modalities recommended by SME contractors to enhance labour in the Western Cape. This study adopted a quantitative research methodological choice, and therefore, collected data was based on an online survey questionnaire applied through Google Forms to the SME contractors registered under the cidb Grade 1 to 6 of General Building (GB). The sampling was of the site management staff of the SME contractors in the Western Cape directed at managing directors, quantity surveyors, construction managers, foremen and site agents. In order to analyse the results, descriptive statistical analyses (Mean Value and Relative Importance Index) and inferential statistics (Factor Analysis) were employed in this study using SPSS. Furthermore, this study made of Cronbachs Alpha in order to ascertain the reliability of the study findings. The results have indicated that SME contractors in the Western Cape consider the following practices important towards improving on-site labour productivity: continuous training and skill building, job satisfaction, and the adoption of new technologies, and compliance with Safety, Health and Quality (SHEQ) regulations and clear instructions and guidelines. The results also revealed the challenges faced by the SME contractors in terms of on-site labour productivity that encompassed poor site layout plan, negligence of labour, alteration of government policies and compliance with labour laws. Also, the findings identified key factors for enhancing effective on-site labour productivity, which include the level of skill of the labour, the motivation, the training, the external conditions and the influence of the stakeholder. Regarding SME contractors’ modalities for improving on-site labour productivity, the results indicated the presence of excellent task supervision, monitoring of construction equipment (via telematics), employment of labour-assistive robotics and addressing labour-related issues promptly and fairly. In conclusion, on-site labour productivity of SME contractors can be improved by means of constant training and development of on-site labour, appropriate supervision and site management and the use of technology.

Addressing the energy challenges, particularly load-shedding, it determines system performance and cost effectiveness. The primary research question revolves around identifying the optimal configuration of a solar PV system with battery backup, considering energy consumption patterns, and other site-specific factors like climatology data. Literature gaps in adequately addressing the techno-economic assessment of solar PV systems with battery storage for commercial use in South Africa exist. A literature review of the system components, effects of factors affecting technical performance as well as similar previous studies was conducted. The employed approach involves using simulation tools like PVSyst to determine the system’s output and configuration and conducting a techno-economic analysis to determine its viability. The methodology involves using monthly electricity consumption data from a commercial site in Cape Town and utilising PVSyst to estimate energy yields, performance ratios, and system losses. The technical analysis formed the basis of system sizing and configuration, with a bill of quantities compiled to estimate system capital costs. The designed system, with an 82.2% performance ratio, includes two 50 kVA hybrid inverters, a 102 kWp solar panel array and 80 kWh energy storage. Economic analysis, using customised Excel worksheets, evaluated the project’s net present value (NPV) of R45 358 870.35, internal rate of return (IRR) of 27.55% and a discounted payback period (DPP) of 3.4 years. Ethical considerations ensure transparency and integrity. Anticipated outcomes include insights into solar PV system yields, performance ratios, and economic viability, aiding decision-making for stakeholders and promoting renewable energy adoption. The findings aim to inform the adoption of renewable energy solutions in South Africa, contributing to the sustainable energy transition.

Understanding construction dynamics workforce and the socioeconomic significance of inclusive practices, the study creates a holistic leadership framework that combines diversity management and inclusive leadership principles to boost team and individual performance in construction project delivery. A sequential mixed-methods approach was used, beginning with quantitative data gathered from structured surveys given to construction professionals involved in leadership position, followed by qualitative interviews with industry leaders and stakeholders. To collect quantitative data, organised (135) surveys was distributed to construction team involved in leadership positions such as construction managers, and site supervisors to leadership practices, engagement levels, diversity and inclusion practices. This method enables measurable information about how leadership affects team and individual productivity in construction project delivery. In addition, qualitative data was collected through (5) semi-structured interviews with diverse contractor management teams who took part in survey to acquire a better understanding of the difficulties and tactics associated with diverse and inclusive leadership. This study adopted a combination of descriptive and inferential statistics to comprehensively interpret and analyse quantitative data. The use of mean ranking and standard deviation was adopted in descriptive analysis, while factor analysis was adopted to further explore the underlying relationships among variables, identifying key leadership practices adopted by contractors and inclusion strategies that significantly impact team and individual productivity. For qualitative data analysis from interviews, content analysis was adopted to systematically code and categorize responses, allowing for the identification of recurring themes and insights into leadership, diversity and inclusive practices. The quantitative findings reveal patience, patience, humility, and lead by example as the leadership characteristics patenting to general management of leadership. Moreover, this study reveals inclusive decision-making, proactive diversity initiatives to empower the workforce, and problem-solving skills as effective leadership characteristics linked to Workforce productivity leadership. Factor analysis revealed the following components celebration of success and achievement of the workforce, problem-solving skills, conflict resolution skills, and emotional intelligence to empower the workforce. On the other hand, the qualitative findings reveals the following leadership characteristics, effective communication skills, employee support and coaching, adaptability and flexibility, empathy and emotional intelligence, integrity and accountability, motivational and innovative leadership, fairness and patience, and inclusive decision-making. Concerning leadership management practices this study uncovers that demonstrating behavior when engaging the workforce, accountability, and commitment to organisational goal as the leadership commitment indicators. While, mentorship programme to support workforce career development, accessibility of mentorship programmes to all employees, and mentorship programmes are adopted to ensure the retention and advancement of diverse workforce are revealed as mentorship and sponsorship programmes. Regarding inclusive policy the findings from this study reveal feedback-oriented policy, the clear and explicit policy articulated organisational commitment to diversity equity and inclusion, and proactive and preventative measures highlighted in the policy. The findings from celebrating diversity within the organisation reveals that contractors adopt diversity and inclusion awards, employee’s spotlight, diverse cultural event, and community partnership. The qualitative findings reveal the following leadership management practices that include flat line management structure, mentorship and skills development, performance reviews and reward systems, inclusive recruitment practices, bias confrontation and accountability, encouraging independent thinking, commitment to a safe and inclusive environment, effective communication strategies, and diverse team formation. The quantitative findings reveal the following components concerning employee engagement and inclusion comprising cultural awareness training, promoting a sense of ownership among employees, encouraging employees to participate in community engagement, leadership engagement and visibility, and prioritise employee’s well-being. The qualitative findings reveal the following employee engagement and inclusion practices including effective communication and feedback, inclusive decision-making, recognition and reward systems, team building activities, respect for cultural diversity, fostering a valued and open culture, and coaching and direct support from management. Additionally, the study identifies key barriers to implementing diversity and inclusion initiatives, including resistance to change, limited leadership commitment, and inadequate policy enforcement to name few. Based on these findings, this research recommends a leadership framework that prioritises inclusive decision-making, diversity training, and accountability measures to enhance contractors workforce productivity.
