  • Description: Abstract: Growing population, industrialization and infrastructure development have resulted in enormous waste generation over the past decades. The disposal of vast amounts of waste remains a major challenge. However, in the globalized world recycling has become a main option for managing wastes while in other parts of the globe, landfilling is resorted to because of waste handling difficulties. South Africa is one of many countries where landfilling activities is high, as roughly 75 % of daily generated solid waste is disposed in landfills. This includes massive amounts of construction and demolition wastes (CDW) from reconstruction and development activities. South Africa depends on landfilling as a system of waste management which in the foreseeable future would linger on till feasible recycling options are initiated. Consequentially, the generation and seepage of leachate into soil, ground and surface water reserves is probable in such dump sites due to exposure of the waste bodies to rain and run-off water. A bespoke device was used in the study to investigate the impacts of disposing CDW in open dumps with mind for an unlined site relying on the geology of the area as worst case scenario. To generate leachate, the device was coupled with CDW in a bottom chamber and de-ionized water seeped through from a reservoir. Arsenic, Copper and Chromium from the generated leachate were analyzed by full spectral method on the effluent and were compared to South African standard of drinking water. Although, concentration levels of the targeted ions decreased through the test, it was clear that if CDW is not properly disposed, could contribute to consequential impacts on human and environmental health over time.

  • Description: Abstract: This article examines how students’ geographical background influences their satisfaction with university hall of residence. The reason for this study is bore out of the fact that the diversity of geographical background is a major issue in post-apartheid South Africa as most students’ comes from diverse background. Moreover, few studies have been conducted to explore relationships between cultural differences and the housing satisfaction of university students in South Africa. The primary data for the study was collected through a structured questionnaire survey distributed to a sample of 60 occupants’ from a female hall of residence at the Doornfontein campuses of the University of Johannesburg. The findings from the survey revealed that 26.67% of the students reside in urban areas while 73.33% of the students reside in rural areas, township and informal settlement. Further findings revealed that the urban students were less satisfied with specific features in the hall of residence while student’s who reside in the rural area, ‘location’ and informal settlement were more satisfied. However a unified finding in the study revealed that students’ from different geographical background were satisfied with the neighbourhood facilities. Diversity of geographical classification is a major issue in many societies as no society is mono-ethnic. Hence there is a need to determine the influence of geographical diversity in students housing so that universities can better serve students’ needs.

  • Description: The purpose of the paper is to investigate current challenges and problems facing small and medium size contractors (SME) in Mbombela (Nelspruit) - Mpumalanga Province of South Africa. This study was necessitated because the importance of small and medium sized enterprises in national building and economic development is of paramount importance in the South Africa economic debate. The primary data for the study was collected through a structured questionnaire survey which was distributed to Small and medium contractors within grade 1-4 of the South Africa Construction Industry Development Board. The survey results indicated that external factors such as high competition when tendering for construction jobs within the CIDB category is a major challenge the SME’s face’s in the procurement of work. Also, internal factors such as poor administrative management within the company, lack of skilled professionals and lack of capacity to deliver on certain project were the greatest challenges faced by the construction companies. The scope of this study is only focused on small and medium size contractors in Nelspruit (Mpumalanga province). In addition, the study is not focused on large established contractors in South Africa. The South African construction industry will continue to provide jobs but intervention is needed to develop the SME’s contractors who contribute a greatly to the economy.

  • Description: The objective of this paper is to investigate the effectiveness of learnership programmes in the South African construction industry. This will be achieved by first establishing whether the Learnership System introduced under the Skills Development Act No. 97 of 1998 is an appropriate system for training construction professionals and by investigating the quality of the learnership outcome. The paper is also aimed at investigating the major obstacles faced in delivering effective learnerships in the construction industry. The methodology for the research was solely a literature review. The literature review was based on literature focused on the legislation governing the learnership programmes, stakeholders involved in the delivery of learnership programmes, the outcomes of learnership programmes and major obstacles hindering the effectiveness of learnership programmes. The literature survey revealed that there is a considerable confusion and ignorance amongst training providers. This factor was found to have a negative impact on the delivery of efficient and effective learnership programmes in the construction industry. Further findings also revealed that other factors contributing to the ineffectiveness of construction learnership programmes are poor administration and bureaucracy within the Construction and Education Training Authority, poor outcome of learnerships, dissatisfaction with the system amongst learners and employers for different reasons and technical incompetence amongst trainers. Learnerships in the construction industry have not been effective and efficient in terms of skills development as predicted. This is attributed to many factors such as ignorance and confusion amongst stakeholders, bureaucracy and poor administration within Construction Education and Training Authority, lack of support from various relevant stakeholders and low levels of employer participation in the delivery of learnership programmes.

  • Description: Abstract: The growth of small and medium-sized construction firms (SMEs) undoubtedly remains an important consideration within socio-economic activities in the Ghanaian economy. Literature has established both tangible and intangible benefits that emanate from the activities of construction SMEs within the sector. Further, literature has also not reached consensus on a unified definition of what firm's growth constitute. Firm's growth is rather considered from the perspective of both internal and external determinants which makes comprehending growth vague. This study, however, conceptualized the growth of Construction SMEs with details of firm's growth indicators. In order to establish the aim of the study, semi-structured interviews supplemented by a review of existing literature on firm's growth was adopted to drive similar and new constructs that have informed this study. The study provides a significant conclusion to the study which includes the main determinates of firm's growth such as the entrepreneurial feature of the firm characteristics and the business environment of the firm. Also captured in the conclusion are necessary growth barriers that must be controlled if growth within the construction SMEs in Ghana is to be achieved.

  • Description: Abstract: The growth of small and medium-sized firms (SMEs) of most economies both developed and developing is not underestimated. This is because SMEs in particular, the construction SMEs are characterised as an engine of growth in facilitating employment, socio-economic and developmental needs of a nation. Ghana, in view of its status as a developing economy, is also driven by the impact and activities of the Construction SMEs. Therefore, the growth of construction SMEs is so pertinent to the Ghanaian economy due to enormous benefits that are achieved. As a result, it is significant for the study to explore into the gaps that will enhance the growth of these firms. The study adopted a mixed methodological approach including a review of literature supported by the use of electronic questionnaire survey in order to achieve this objective. The study established the paramount growth gaps among SME construction firms as the less attention on stakeholder's involvement and educational training. Further findings from the study also revealed that growth of construction SME firms are influenced by three core determinants namely entrepreneurial features of firm owner, firm characteristics and the business environment that the firm operate. Conclusions from the study suggest that SMEs firms do not engage in educational training activities due to the perceived associated cost involved. Further conclusions also stressed that the construction activity is accompanied with vast stakeholders, and, therefore, there is always the challenge of selecting from the identifying stakeholders to contribute to the firm's growth.

Investigating the hindrances of implementation of occupational health and safety among small medium enterprise’s in the Gauteng Province of South Africa. Proceedings of the Creative Construction Conference.
  • Description: Abstract: A positive safety culture requires participation of all stakeholders in construction industry, and is shown through the safety-related knowledge, attitudes, beliefs, behaviour and practices of each worker. Therefore, the study is investigating the hindrances in the implementation of occupational health and safety (OHS) among small medium enterprises (SME’S) in the construction industry in the Gauteng Province of South Africa. A structured questionnaire was distributed to different construction companies and construction workers. From the 70 questionnaires distributed, 42 were brought back and they were all valid and usable. Findings from the survey results obtained from the chosen respondents revealed health safety was known and practiced, however, there are hindrances in the implementation such as poor regular inspections and audits, poor management, poor supervision, lack of material and components, lack of management commitment, equipment and tools, poor communication between workers, poor employers involvement, lack of training and risk education to name a few were the major hindrance in the implementation of occupational health and safety among SME’s. Furthermore, if the challenges could be addressed appropriate and effectively result could manifest such as increased productivity; improve quality work; contractors growth and reduced claims; reduced accidents; reduced rework; improved schedule performance. Management and leadership at all levels are therefore encourage to improve construction OH&S in South Africa among SME’s. Moreover, occupational health and safety of the workers is not negotiable, is all pervasive, increases productivity, and leads to better performance, improve the company image, reduced claims and accidents also reduce lost times spent on injuries. The concept of OHS implementation must be emphasized by the client and the consulting team by way of having occasional not once off, a major workshop to be held three times in a year, to increase the awareness and the seriousness of the implementation of OHS.

  • Description: Abstract: Public-Private Partnerships (PPPs) play an important role in improving the quality of infrastructure service delivery in different countries. In the construction industry, PPPs contribute to skills transfer by the private sector to the public sector and achieving greater efficiency by reducing government bureaucracy and financial burdens. However, these partnerships have challenges that hinder the implementation and delivery of infrastructure. This research examines challenges encountered in the implementation of PPP in construction projects. The study is a literature review/ survey on the challenges faced with the implementation of public private partnership in improving infrastructure service delivery on projects. The study is conducted with reference to existing theoretical literature, published and unpublished research based on international context. However, the challenges specifically are based on literature in Swaziland to identify the challenges they face and the way forward. Other scholars'works were critically examinedtodeterminethe views on the subject. The research revealed that on the political level, there are high expectations with concerns that officials expertise to handle PPP projects are not sufficient, Private sector stakeholders were concerned about the possible dominance of foreign companies. Moreover, labour feared negative consequences for workers, and part of financial sector did not see enough opportunities for PPP in Swaziland. Lack of common understanding and coordination, insufficient planning capacity and structuring support were amongst the challenges faced by PPP in Swaziland.The study will assist the Swaziland Construction Industry in improving their services in terms of delivering construction project timeously since particular strategies can be developed to overcome the identified challenges.

  • Description: Abstract: Previous researchers have proposed that efficient project selection is one of the critical factors that determine project success. Current realities indicate that end users do not accept certain projects despite attempts by these projects at meeting targets of quality, cost and time. Such is the case of certain government-sponsored projects in Nigeria which gets abandoned or fail to attain full utilization. Policy makers assume they know what the people need without consulting them. The value question is hardly adequately answered and agreed upon across the spectrum of stakeholders. The senario above created the need for this research which explores how value management methodologies can be applied to project selection processes in Nigeria. The study adopts mainly the review of literature of value management. The findings showed that a more inclusive, benefits-oriented, value-laden project selection process will lead to a decrease in unused and underutilized public projects in Nigeria. Hence, improving end user satisfaction. This supports the position of established literature and scholarly position in the field of value management which emphasized team oriented, stakeholders inclusive process.

  • Description: Abstract: This article reviews current knowledge of biomimicry and its potential in the sustainability of the South Africa construction industry through materials selection. Biomimicry is the applied science that derives inspiration for solutions to human problems through the study of nature’s designs, processes, and systems. The article evaluates, promotes and encourages the use of biomimetic materials in the South Africa construction industry. An extant literature review was conducted on biomimetic materials, applications and their roles in the achievement of sustainability in the South African construction industry. The study shows that there is a misconception of bioprospected and biopirated materials as biomimetic materials, also, the study found that there are already existing materials that were designed based on biomimicry principles. The paper offers a new approach and strategy to achieving a sustainable construction industry in the South African construction industry through the use and incorporation of biomimetic materials into construction activities. Hence, it is envisaged that new ideas and innovations will be proffered which requires an interdisciplinary collaboration between biologists and other stakeholders in the industry. This study challenges all stakeholders in the South African construction industry on the adoption of biomimicry in their construction practices.
