  • Description: Abstract: The study examines previous literature on the impacts of poor risk management in construction industry, with specific aim of identifying the causes of poor implementation of risk management in construction projects. This is because the concept of risk management has attracted much attention in recent years and that researchers and research bodies, be it corporate or government that try to formulate remedies to poor risk management should begin with an understanding of the causes and impact of poor risk management. The totality of risk management in construction industries include the identification, measurement and prevention of all likelihoods of negative outcomes. The study is conducted with reference to existing theoretical literature, published and unpublished research. The study is mainly a literature review/survey on the cause and effects of poor risk management. One of the primary findings emanating from the study reveals that empirical studies have identified several important factors which causes poor risk management; such as project delays, project failure, reputational damages, and loss of profit, material scarcity, and inadequate project accountability amongst others. The study explores the causes and effects of poor risk management in construction projects and presents a robust background on the theories of poor risk management. This study will enable contractors, stakeholders and construction risk managers to achieve better result and quality projects.

  • Description: Abstract: The construction industry is an important investment-led and dynamic sector that contributes positively to the developmental progress in any economy. However, the construction industry is seen as an ineffective sector owing to the bulky waste it produces. It is also regarded as a key contributor to the negative effect on the environment caused by extreme amounts of waste generated on- and off-site. This study assesses the quantities of waste generated, the factors influencing waste generation, the waste management approaches implemented, the adverse effects of waste and the benefits from construction and demolition waste management implemented in the Nigerian construction industry. The data used in this study were collected from both primary and secondary sources. The primary data were collected through survey questionnaires distributed via emails to the targeted respondents who are construction professionals while the secondary data were collected via the review of related literature. Out of the two hundred (200) questionnaires distributed, only one-hundred and sixty-eight (168) valid data were retrieved and used for the analysis. The collected data accounted for eighty- four per cent (84%) of the entire survey. Furthermore, the reliability of the research survey instrument was tested using Cronbach’s alpha coefficient reliability while a one-way analysis of variance (ANOVA) was conducted to test the hypothesis deducted to quantify the twelve (12) waste materials recognized as waste generated in Nigeria. For the first hypothesis, sig- values were greater than 0.05, which implies that the null-hypothesis (Ho) is valid. The findings show that the most waste generated include concrete, wood and reinforcement, while drywall and bitumen comprise the least amounts of waste generated in the Nigerian construction industry. The T-test carried out on the statistical inferential comparison of the mean variance between the quantity of waste generated on site and the allowable waste shows that the sig- value (0.020) is less than 0.050. This consequently implies that the null-hypothesis (Ho) is not valid. The exploratory factor analysis conducted indicates factors influencing the waste generation are classified into five groups which comprise poor coordination and communication, inadequate planning and design, inappropriate materials transportation and storage systems, inefficient procurement and contractual agreements, and poor project execution and supervision. The approaches employed towards the waste management were also grouped into three (3) which comprise practical legal framework and modular construction, sustainable procurement and material optimization, and proper construction detailing and design. The findings indicate effects such as burden on landfill sites, shortage of land for building construction, air, land and water pollution, release of toxin and emissions of greenhouse gas (GHG) as adverse effects of waste on the environment.

  • Description: Abstract: The aim of this study was to identify the challenges faced in managing multiple projects in the construction industry and by adapting remote monitoring systems can mitigate the challenges presented by multi-project management. Challenges in managing multiple projects simultaneously, include resource scarcity and time and cost constraints. Remote monitoring methods therefore, present opportunities to overcome the challenges associated with multiple projects management. The study drew data from two case studies where remote monitoring and traditional research methods were used. The remote monitoring method utilised automated tools and programmes, which enable project managers to remotely monitor projects. Remote monitoring systems are aimed at optimally empowering the project managers to effectively and simultaneously monitor multiple, geographically dispersed projects in real-time mode using joint tools and human resources... , M.Phil.

  • 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.
