This research seeks to determine&nbsp;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&nbsp;assessed were deemed significant in terms of improving labour productivity. A Kruskal-Wallis test ascertained that there were no statistically significant differences due to the age, gender and experience of respondents. However, statistically significant differences were found due to the designation and educational levels of the respondents. The research study recommends that training on decent working conditions be undertaken and that accentuation of adequate decent working conditions on sites be encouraged. Adequate planning and financing for decent work conditions are also proffered.</p> Tirivavi Moyo, Gerrit Crafford, Fidelis Emuze ##submission.copyrightStatement## http://journals.ufs.ac.za/index.php/as/article/view/4165 Thu, 12 Dec 2019 00:00:00 +0200 Effectiveness of contractor development programme in KwaZulu-Natal http://journals.ufs.ac.za/index.php/as/article/view/4166 <p>The article investigates the level of satisfaction with the South African Department of Public Work’s Contractor Development Programme (CDP) in terms of its effectiveness. A mixed method research approach (combination of quantitative and qualitative approach) is employed for the collection of both statistical and in-depth information on the perceptions of participants on the CDP. Survey data collected from 364 participants and interview data from six focus-group participants in the KwaZulu-Natal (KZN) province of South Africa forms the data sets for the article. Data was analysed using the Statistical Package for the Social Sciences (SPSS) version 23. Descriptive statistics is used to report the reliability of the various constructs, mean scores, standard deviations, and correlations. The findings show that participants not only deemed the programme unsatisfactory, but also reported an overall negative experience with the programme. Specific findings show that the CDP offers no training opportunities to registered members, lacks effective communication mediums, and benefited only those with political connections. The correlation results show that there is a strong relation between population and registering on the CDP, thus confirming that the open and easy access when registering on the CDP allows any interested person to automatically become a contractor creating the possibility of abuse of the programme. The study was limited to KZN contractors only and may, therefore, not be generalised to the entire national population of contractors. This article is relevant, as it gives insight into how satisfied contractors are with the CDP. It may help potential contractors to consider whether the CDP will be beneficial to them, before they decide to join the programme.</p> Theo Haupt, Weziwe Hadebe, Mariam Akinlolu ##submission.copyrightStatement## http://journals.ufs.ac.za/index.php/as/article/view/4166 Thu, 12 Dec 2019 00:00:00 +0200 An assessment of transformation strategies in South Africa: A multi-case study of the accounting, financial services, government, and construction sectors http://journals.ufs.ac.za/index.php/as/article/view/4167 <p>Globally, transformation is etched in all sectors&nbsp;of the economy. In the South African context, transformation is viewed as the catalyst to address the country’s socio-economic problems and their associated impact on different sectors and the economy at large. However, progress on transformation within the built environment has been slow in comparison with other sectors of the economy. As a result, this has led to a need to examine the transformation processes in the country. This article aims to analyse transformation strategies as conceptualised and implemented by various sectors.&nbsp;The article is based on a multi-case study of identified sectors and organisations that have developed and implemented transformation&nbsp;strategies. The materials used to conduct the study include sector transformation strategies, charters, journal articles, articles published in reputable South African newspapers,&nbsp;organisation reports, information publicly available on the internet, and interviews conducted with sector representatives. The findings show that, for&nbsp;all sectors, transformation strategies are driven through skills development of&nbsp;human resources, with a view to redressing historical imbalances and providing equal opportunities. The process of strategy development involves sectorwide&nbsp;participation and having a champion for the strategy. In order to ensure&nbsp;that strategies are implemented, specific structured training and education programmes from the grassroots to professional level, as well as monitoring of progress are emphasised. Recommendations are made in line with the findings in order to guide the Council for the Built Environment in the development of a strategy for the built environment.</p> Innocent Musonda, Trynos Gumbo, Chioma Okoro ##submission.copyrightStatement## http://journals.ufs.ac.za/index.php/as/article/view/4167 Thu, 12 Dec 2019 00:00:00 +0200 Theoretical model of trust-based relationships in building information modelling supply chain for construction projects http://journals.ufs.ac.za/index.php/as/article/view/4168 <p>The structure of relationships among project&nbsp;participants has a significant impact on&nbsp;trust development, while the number of&nbsp;participants involved in the relationship&nbsp;increases the complexity of trust. Hence, it&nbsp;becomes inappropriate to generalise the&nbsp;existing dimension and components of trustbased&nbsp;relationships to trust-based relationships among the building information modelling&nbsp;(BIM) supply chain members because of the&nbsp;multiple structures of relationship and the&nbsp;numerous interpersonal and inter-organisations&nbsp;that participate on BIM-based construction&nbsp;projects. This article investigates the nature of&nbsp;trust-based relationships among the BIM supply&nbsp;chain members and establishes whether the&nbsp;requirements of&nbsp; the BIM process influence&nbsp;trust-based relationships among the BIM supply&nbsp;chain members. A five-stage PRISMA was&nbsp;adopted for systematic reviews and meta analysis.&nbsp;The systematic review enabled the&nbsp;development of a theoretical model of trustbased&nbsp;relationships in BIM supply chain which&nbsp;was subjected to meta-analysis for validation.&nbsp;The findings revealed that trust-based relationships among the BIM supply chain members entail trusting and trustworthy behaviours, positive expectations, and&nbsp;positive reputations, under which twenty-seven components were identified&nbsp;and classified appropriately. The article concludes that the nature of trustbased&nbsp;relationships among the BIM supply chain members, as influenced by the requirements of the BIM process, can be explained as trusting and trustworthy behaviours, positive expectations, and positive reputations. The article advances the understanding of trust-based relationships among the BIM supply chain members and recommends a first-hand investigation into the nature of trust-based relationships among the BIM supply chain members in future studies.&nbsp;</p> Oluseye Olugboyega, Abimbola Windapo ##submission.copyrightStatement## http://journals.ufs.ac.za/index.php/as/article/view/4168 Thu, 12 Dec 2019 00:00:00 +0200 Factors influencing professionalism and the viability of local firms in Nigeria http://journals.ufs.ac.za/index.php/as/article/view/4169 <p>It is imperative to know the place of&nbsp;professionalism in the viability of local construction firms (LCFs) in developing countries. This article identified and examined&nbsp;various factors related to professionalism from diverse aspects that influence firms’ viability&nbsp;in the construction industry. From a literature&nbsp;review, 37 variables influencing the viability of&nbsp;local construction firms were identified of which&nbsp;19 relate to professionalism. 177 staff from&nbsp;LCFs who were awarded building contracts in&nbsp;selected institutions in Nigeria were requested&nbsp;to rate the importance of each viability factor&nbsp;on a 5-point Likert scale. Mean score ratings&nbsp;and principal component analysis were used to identify and summarise the most important factors. Three of the four “extremely important” factors are directly related to profes-sionalism&nbsp;in the construction industry: organisational competence, quality of work and services, and&nbsp;quality of construction work and services, with&nbsp;mean scores of 4.4, 4.31, and 4.30, respectively.&nbsp;Out of the 11 component&nbsp; factors obtained,&nbsp;three topmost factors are directly related to professionalism in the construction industry.&nbsp;These factors were labelled: "construction resources” (9.27%); “improved construction method” (3.24%), and “quality&nbsp;service and satisfaction” (2.84%). These factors substantiate the importance of&nbsp;professionalism in the viability of LCFs and should motivate various professionals in the construction industry to demonstrate their effectiveness in good service&nbsp;delivery and ethics.</p> Olubimbola Oladimeji ##submission.copyrightStatement## http://journals.ufs.ac.za/index.php/as/article/view/4169 Thu, 12 Dec 2019 00:00:00 +0200
