South Africa is challenged with an increased backlog of adequate subsidised affordable housing for the marginalised in well-located areas that provide access to urban amenities and places of employment. However, the perception of subsidised affordable housing developments built in the urban core in close proximity to bonded properties is significantly negative. This article seeks to address whether the presence of subsidised affordable housing provided through South Africa’s Integrated Residential Development Programme (IRDP) impacts on the property value of bonded properties located nearby. This article examines the impact of the subsidised affordable housing development of Fleurhof, Johannesburg, on surrounding property values. It investigates, in particular, whether the IRDP housing development decreases property values. Using hedonic pricing models (HPM) with regressions, the housing attributes (characteristics) and property price data, dating from 2001 to 2017, were used to determine the effect on the value of Acta Structilia 2020: 27(1) 30 properties in the suburbs of Meadowlands East Zone 1 and Orlando West in Soweto and Florida in Roodepoort, as the two closest residential communities to Fleurhof. The article reveals that the close proximity of the housing development in the initial stages (2001-2010) of the development affected property values negatively. However, in the long run, the housing development does not affect property values.

The structure of relationships among project participants has a significant impact on trust development, while the number of participants involved in the relationship increases the complexity of trust. Hence, it becomes inappropriate to generalise the existing dimension and components of trustbased relationships to trust-based relationships among the building information modelling (BIM) supply chain members because of the multiple structures of relationship and the numerous interpersonal and inter-organisations that participate on BIM-based construction projects. This article investigates the nature of trust-based relationships among the BIM supply chain members and establishes whether the requirements of the BIM process influence trust-based relationships among the BIM supply chain members. A five-stage PRISMA was adopted for systematic reviews and metaanalysis. The systematic review enabled the development of a theoretical model of trustbased relationships in BIM supply chain which was subjected to meta-analysis for validation. Acta Structilia 2019: 26(2) 108 The findings revealed that trust-based relationships among the BIM supply chain members entail trusting and trustworthy behaviours, positive expectations, and positive reputations, under which twenty-seven components were identified and classified appropriately. The article concludes that the nature of trustbased 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.

A quantitative research approach enabled a self-administered 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.

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. algehele negatiewe ervaring met die program gerapporteer het.

It is imperative to know the place of professionalism in the viability of local construction firms (LCFs) in developing countries. This article identified and examined various factors related to professionalism from diverse aspects that influence firms’ viability in the construction industry. From a literature review, 37 variables influencing the viability of local construction firms were identified of which 19 relate to professionalism. 177 staff from LCFs who were awarded building contracts in selected institutions in Nigeria were requested to rate the importance of each viability factor on a 5-point Likert scale. Mean score ratings 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 professionalism in the construction industry: organisational competence, quality of work and services, and quality of construction work and services, with mean scores of 4.4, 4.31, and 4.30, resources” (9.27%); “improved construction method” (3.24%), and “quality service and satisfaction” (2.84%). These factors substantiate the importance of professionalism in the viability of LCFs and should motivate various professionals in the construction industry to demonstrate their effectiveness in good service delivery and ethics. gemiddelde punt 4.31, 4.30. 11 faktore wat verkry is, is faktore verwant professionaliteit in die konstruksiebedryf. faktore is gemerk: konstruksiemetode” en

Globally, transformation is etched in all sectors 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. The article is based on a multi-case study of identified sectors and organisations that have developed and implemented transformation strategies. The materials used to conduct the study include sector transformation strategies, charters, journal articles, articles published in reputable South African newspapers, Acta Structilia 2019: 26(2) 72 organisation reports, information publicly available on the internet, and interviews conducted with sector representatives. The findings show that, for all sectors, transformation strategies are driven through skills development of human resources, with a view to redressing historical imbalances and providing equal opportunities. The process of strategy development involves sectorwide participation and having a champion for the strategy. In order to ensure 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.

The article aims to determine the challenges faced by newly established quantitysurveying firms (NEQSFs) in securing tenders in South Africa. A quantitative research approach was implemented in the study which included a literature review and a questionnaire survey to identify the barriers experienced by NEQSFs. The results revealed that the specific challenges faced by NEQSFs are political influence and corruption in the awarding of tenders, excessive discounting of professional fees, and favouring large and established firms over NEQSFs. This article is relevant, as it contributes to the understanding of key challenges faced by NEQSFs and reveals gaps to be filled in order to position these new firms on a higher platform to be able to operate within the profession. Furthermore, it also demonstrates to potential entrepreneurs the importance of considering these challenges in the start-up and growth of their businesses.

There is increasing concern regarding the impact of the consumption of cannabis by construction site workers on workplace safety and performance. This preliminary study explores the use of cannabis as a psychotropic drug and its consequences and effects on construction workers, considering the decriminalisation of its private use and personal consumption in South Africa. These consequences and effects can be characterized as being behavioural, perceptual, physiological, emotional and cognitive. This study is a precursor for a more detailed ongoing study. The article was developed based on a review of empirical and theoretical studies previously published in a wide range of journals and commissioned reports. Literature relating to drug and substance use in the construction workplace was obtained from research databases. The keywords “cannabis” and “construction industry” were used to search the databases. Of the number of related articles found, a total of 41 articles and reports were cited in the study. The study reveals that cannabis use has short-term health effects such as acute mental illnesses, which could result in impaired reasoning and perceptions. Long-term effects of frequent and continuous cannabis use include respiratory infections and hyperactivity. Theo Haupt • An appraisal of the use of cannabis on construction sites 149 Furthermore, the after-effects of the use and abuse of cannabis by construction workers poses numerous threats to the workplace safety of the construction industry. The article identifies loss of concentration and low productivity on site, abnormal and irrational behaviour, absenteeism from work and poor work quality as impacts of cannabis use on construction sites. The article highlights the need for site supervisors and construction employers to introduce improvement mechanisms to control the use of cannabis on construction sites.

This article examines time and cost performance of projects executed by small and medium-sized construction firms with a view to enhancing the firms’ capabilities. The study adopted a quantitative descriptive analysis based on primary and archival data. Sixty-eight (68) valid questionnaires obtained from top managers of the firms provided primary quantitative data for the assessment. Secondary data were collected on the initial and final contract sums as well as on the initial and completion times of 184 public projects executed by the firms. Data collected were analysed using descriptive analysis. The findings indicated that the small firms specialised in general building works, while the medium-sized firms specialised in civil works, in addition to general building works. Project values in the case of small construction firms ranged between N1 million and N50 million, while those of medium-sized construction firms ranged between N51 million and N100 million. The performance index (PI) of the projects executed by the firms showed a general underperformance level. Approximately

Abandoned projects have contributed significantly to the inadequacy of teaching and research facilities in the Nigerian tertiary education institutions. This article examines the strategies for resuscitating the projects based on the financing options that were employed. The aim of this article is to suggest sustainable cash-flow strategies that could be appropriated for financing abandoned projects, in general, and tertiary education institutions projects, in particular. The article adopts a triangulation of qualitative and quantitative methodology. The respondents consist of 47 top officials in the physical development departments in Osun State public tertiary institutions. The qualitative assessment is based on open-ended face-toface interviews involving three key informants, namely one quantity surveyor and two engineers. Data collected are analysed using mean analysis, Kruskal-Wallis (K-W) test, and ATLAS.ti 7. Acta Structilia 2019: 26(1) 168 Solicitation for funds and yearly budgetary allocation were both frequently used and were efficient strategies. On the other hand, public-private partnership (PPP) arrangement, and the establishment of institution-based, abandoned projectresuscitation unit/department, and levy of beneficiaries were strategies that were both least used and inefficient. The article provides implications for financing abandoned educational projects in the education sector.
