  • Description: Abstract : In the face of slowing economies globally, the construction industry faces many challenges such as socio-economic stress, resource shortages, institutional weaknesses and a general inability to respond to key issues. These have intensified and become more severe in recent years. Empirical research in supply chain management points to barriers that limit construction industries in developing countries such as South Africa. This paper aims to explore supply chain constraints in the South African construction industry. Relevant literature was reviewed and insights from 15 experienced supply chain practitioners were elicited by means of semi-structured interviews. Content analysis was employed using the ATLAS.ti (version 7) software to analyse qualitative data. Six themes emerged from the interviews, which include lack of investment in supply chains, lack of supply chain innovation process constraints, supply chain change management, supply chain collaboration, supply chain leadership, and time management. It is recommended that construction companies adopt supply chain management systems, integrated solutions, and collaborative project management tools and technologies.

  • Description: Abstract: The rotating cylinder electrode (RCE) is one rig constructed and designed to study the behaviour of the material under the effect of flow. The behaviour of hot and cold rolled UNS S32205 duplex stainless steel (DSS) in erosion-corrosion (EC) conditions were studied to monitor the material loss and surface degradation. The impact is highlighted and explained with the aim to offer better understanding regarding degradation phenomena. Mine water solution containing silica sand particles (SiO2) was the environment of interest for this study. Both gravimetric and electrochemical methods (potentiodynamic polarisation (PP) and open circuit potential (OCP)) were adopted for the erosion-corrosion behaviour of the alloys. The cold rolled material displayed better resistance to erosion-corrosion at all speed tested in comparison with hot rolled material. The surface morphology for both materials revealed erosion dominating the erosion-corrosion process with minimal evidence of pitting. The hardness of cold rolled sample showed higher hardness as compared to hot rolled due to the impingement by sand particle hence better resistance to erosion-corrosion. The wear corrosion mechanism displayed grooving on the material surface especially at a higher speed. The effect of particles in wear mechanism play an important role. The electrochemical results showed increasing corrosion rate as the rotating speed of the electrode increased. The higher pH of mine water solution resulted in the passivation of the sample. The analysis trend was not surprising as the vulnerability of the surface layer increased with increasing velocity under the subjected conditions. Aggressive conditions and sand concentration are good enough to prove relation between wear rate and corrosion rate. The environmental impact was not aggressive enough to create much interferences hence the surface deterioration was not severe in all analysis. , M.Ing. (Engineering Management)

  • Description: Abstract: Construction accidents and fatalities bear heavily on companies. Thus, achieving zero accidents on construction projects is a desired goal universally. The present study aims to identify critical conditions or factors to ensure zero accidents on projects. A field questionnaire survey was used to collect data in different locations in Gauteng. Participants were selected using snowballing and judgemental sampling techniques. Empirical data were analysed using EXCEL to output descriptive statistics including mean item scores and standard deviation. The factors were further ranked to identify the most important as perceived by the sampled respondents. The study found that clear H&S goals, regular recording of accidents and incidents, regular tool box talks as well as following strict H&S rules, procedures and processes were the most indicators of a good safety record among the sampled organisations. On the other hand, involving staff in H&S planning and worker incentives did not appear to have much bearing on achieving zero accidents in the organizations sampled. The study was conducted in only one Province in South Africa and may not be generalisable to construction organizations in entire country or other geographical areas. The current research identifies factors necessary to prevent or avoid accidents on construction sites. Continuous health and safety improvement is likely if factors to prevent accidents are taken into account to prevent their occurrence.

  • Description: Abstract: This study adopted a quantitative approach as the purpose was to investigate the challenges faced by stakeholders in the road construction projects in the Gauteng province of South Africa. This study adopted quantitative research and a well-structured questionnaire was distributed to different construction companies in Gauteng Province, which were registered with various approved councils construction professionals and contractors such as civil engineers, project managers, directors, quantity surveyors, construction managers and resident engineers. The questionnaires were sent via e-mails, some were delivered to the known construction companies by the researcher and some were distributed during site clarification meetings of contractors and consultant’s bidders on Gauteng Department Roads and Transport tenders.75 Questionnaires were distributed and 50 came completed and eligible to use. Random sampling method was used to select the respondents in various organizations. Research findings revealed that Community unrest and land proclamation were the highest ranked factors that pose a major challenge in the road construction, time, financial constraints, cash flow, lack of proper panning, resources, delivery of material, plant and equipment, shortage of skilled labourers, lack of equipment, lack of materials, performance guarantees, project duration/period, cost overruns were the major challenges facing the stakeholders in roads construction projects in South Africa. In conclusion, proper planning, communication is vital to overcome the challenges and government at the other hand needs to partner with private companies in terms of transferring skills and upgrading the upcoming contractors by emerging them with sustainable, independent contractors. Therefore, any challenges found in roads construction might be eliminated in the future projects by lesson learned, by planning for the upcoming project properly and also by identifying possibility risk at the early stage of the project.

  • Description: Abstract: Collusion is an unethical and disreputable agreement among parties of similar interests with the intention of achieving a goal through immoral and dishonest means. Proper ethical procurement practice in the construction industry, will enable the Construction Industry Development Board (CIDB) to achieve their mandate which is to promote uniformity in the construction procurement; efficient and effective infrastructure delivery; and development of the emerging contractors, including transformation. Furthermore, the Competition Commission of South Africa (CCSA) to also achieve their mandate which is fair competition in all industries. With collusion in existence it will be difficult for the CIDB and CCSA to achieve their mandate. This study examined the influences of this practice among competitors and stakeholders in the construction industry. Various causal factors of collusion among parties were extracted from review of existing and relevant literature materials and they were further evaluated to arrive at the specific ones that are relevant to the construction industry and selected area of study. Using these factors, close-ended questionnaires were prepared and administered to construction stakeholders with adequate level of experience in the construction industry. The number of questionnaire distributed is 50 and 45 were returned out of which 5 were not correctly and completely filled. The distribution method used was self-administration. In addition, purposive sampling was used. The findings from the 40 respondents indicates that the major cause of collusion in the construction industry is greed of various stakeholders that are shouldered with the responsibilities of managing and monitoring construction contracts and activities especially the contractors. Political influence was also identified as a major reason for collusion among other factors. [Empowering emerging contractors, a well regulated environment, a fair competition,..

  • Description: Abstract: Research about the implementation of health and safety (H&S) in the construction industry is required, as it may create more awareness on strategies to significantly reduce the rate of incidents and fatalities in construction organisations. It may encourage such organisations to improve their H&S performances on construction projects. The aim of this research is to establish the drivers of H&S implementation in construction organisations within the Gauteng Province in South Africa. The research adopted a quantitative research methodology. A survey questionnaire was used to collect primary data. Judgemental and snowball sampling techniques were employed to select the respondents consisting of site engineers, site agents, contracts managers, construction managers and project managers. Data were analysed through descriptive statistics, mean item score and standard deviation. Findings indicated that the most important drivers are the need to manage hazards; organisations regard H&S as important; compliance with the legislation; consideration of H&S as a way to do business and to reduce costs associated with accidents and injuries. These results may assist construction organisations in setting H&S as a priority, since little attention has been paid to the objective of H&S implementation. This study was restricted to large construction organisations within the Gauteng Province in South Africa and therefore may not be generalizable to all construction organisations within South Africa and in other geographical locations.

  • Description: Abstract: The complex nature of the architectural, engineering and construction industry and increasing demand for innovative and technical construction projects by clients, have resulted in increasing adoption and application of information technology at the design, construction and post-construction phases. One of the current innovative technological method is automation, which has gained popularity in some sectors of the economy like manufacturing, banking and entertainment, among others. To promote the usage of this technique in the construction industry, this study examines a number of success factors for the adoption of automation for various activities and processes involved in execution of construction projects. Using survey method, a close-ended questionnaire was designed around 18 drivers obtained from existing and related literature materials on automation and construction process. The research instrument were thereafter administered to 50 construction professionals including architects, engineers, construction managers, quantity surveyors and construction project managers...

  • Description: Abstract: The purpose of this study is to determine the types of accidents that lead to permanent disability of construction workers resulting in early retirement. The data was obtained from Federated Employer Mutual Assurance (FEM). The types of accidents were analysed from the decade of data from 2007 to 2016. The data was analysed using descriptive and inferential statistics. The analysis established that 7 670 accidents were experienced in the construction industry from 2007 to 2016, of which the major cause of accidents in the construction industry in South Africa was being struck by e.g. object while working. Furthermore, the highest average cost of accident was when a construction worker was electrocuted, the average cost was R214 767.00. The most fatal accidents was caused by motor vehicles. The study further established that there is a 10% chance of a construction worker to be permanently disabled and take early retirement or permanently disabled without taking early retirement when involved in any type of accident while at work. In conclusion construction workers using any work related vehicle, either being transported to site or using the vehicle on site, caution should be adhered to in order to prevent fatalities. The government of South Africa should ensure that strict measures are taken for drivers who do not observe the traffic rules on site and on the public roads. This will ensure the prevention of permanent disability, among the construction workers in South Africa. It is also imperative for construction workers to receive training on health and safety when they work in any construction project, this need to be emphasized on a daily on site by the construction health and safety practitioners. The authors recommends a further study on the type of injury and ill-health associated with the type of accident that force the construction worker to retire early.

  • Description: Abstract: The construction industry in South Africa plays a major role in the country’s GDP. It plays a significant role in the ability to boost growth for the country and create temporary and long term employment for many individuals. With the high number of emerging construction companies failing to succeed within the first 3 years after being established, there is an increasing risk of having a high unemployment rate in the country. The study focuses on factors which contribute to emerging construction companies failing to succeed and how successful companies are able to overcome failure in the same industry. Through literature 8 factors were identified as being the factors which contribute to failure for emerging construction companies. Questionnaires distributed via an online survey where used to collect data from individuals who own companies with Construction Industry Development Board(CIDB) grade 1 - 4 or individuals who are in management positions in companies with grade 5 - 9. From the results it was found that poor managing of company finances by leadership is the biggest reason emerging construction companies fail to sustain. It was found that established companies manage the 8 factors identified from literature better compared to emerging companies and thereby are able to overcome failure. The study has contributed to the limited knowledge available to the construction industry about why emerging construction companies fail to succeed by identifying the causes and what to do to avoid failure. , M.Phil.

  • Description: Abstract: Collusion is an unscrupulous and anticompetitive practices among construction stakeholders which has adverse effect not only on the integrity of the parties or people but also on the overall performance of construction projects. In view of this and in order to ensure healthy competition and alliance among construction stakeholders, this study assessed various measures that can be adopted to minimize or eliminate the practice of collusion in the construction industry. The measures were extracted from existing literature materials and questionnaire was adopted as a means of data collection using a 5-point Likert scale. Using convenience sampling, 49 questionnaires were distributed, 43 were retrieved while 41 were found worthy of further analysis. Among other measures, people involved in construction process including the professionals should be encouraged to report any suspicious acts and transactions including collusion practices, and procurement procedures for construction projects should be open and transparent. There is a need to blacklist and deregister professionals and companies that are caught in the act of collusion as this will enhance project performance and subsequently improve the image of the construction industry. Punishments for the offence should be well documented and there should be strict enforcement of the discipline and regulations when a company or individual is found culpable. This study will help regulatory bodies shouldered with the responsibilities of regulating construction activities - including that of the stakeholders - in their quest to reduce or eliminate the practice of collusion in the construction industry.

  • Description: Abstract: Managing risks in construction projects has been acknowledged as an essential management process in order to accomplish the project objectives in terms of time, cost, quality, safety and environmental sustainability. However, up to now most studies have concentrated on some aspects of construction risk management rather than using a systematic and comprehensive approach to identifying risks and analyse the probability of occurrence and impacts of these risks. Risk management consists of identifying risks, assessing risks either quantitatively or qualitatively, selecting the appropriate method for handling risks, and then monitoring and documenting risks. By identifying risks in an early stage of planning and assessing their comparative significance, project managers can identify techniques employed to reduce risks and allocate the best people to mitigate them. Thus, this research focuses on risk identification, as opposed to other processes of risk management. This research is mainly a literature review and was conducted through accredited academic and Professional journals, books, the internet, theses, and dissertations. The reviewed literature revealed that the entire risk management process is not only limited to solving problem in advance but also for the occurrence of any unexpected future problems. The study further shown that issues with possible threats envisaged in a project are not only a means to reduce losses within the project, but also a means to transfer risks into opportunities, which can lead to economic profitability, environmental and other advantages. This paper is of value to managers and decision makers involved in managing risks where it is intended to boost their knowledge regarding the importance of risk identification as a crucial stage of the process to managing risks.
