- Description: Abstract: This study provides a holistic assessment of the current waste management strategies implemented in Nigerian construction projects. 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 of the targeted respondents who are construction professionals in the study area of Lagos metropolis, while the secondary data were collected via the review of related literature. Out of the 200 questionnaires distributed, only 168 valid forms were retrieved. The collected data accounted for 84% of the entire survey and were suitable for the analysis. An exploratory factor analysis was conducted while the reliability of the research survey instrument was tested using Cronbach’s alpha coefficient reliability. The result indicated that the waste management strategies were clustered into three groups, comprising practical legal framework and modular construction, sustainable procurement and material optimisation, and proper construction detailing and design. In conclusion, the waste management strategies implemented in Nigeria were assessed as being “not sustainable enough”. However, it is recommended that there is an upgrading in either the approach or method of application of waste management strategies in order to ensure its sustainability.

- Description: Abstract: The role of skills development in attaining productivity and competitiveness in industry and global level cannot be overemphasized in the construction sector. The study aims to evaluate the critical skills needed in the construction industry. A quantitative study was conducted and data were collected using questionnaires distributed among construction professionals including project managers, construction managers, quantity surveyors, architects and engineers based in South Africa. The data amassed were analyzed to output descriptive statistics. The skills were ranked according to the level of priority as perceived by the respondents. Findings from the empirical data analysis established that the critical skills needed within the construction industry at present and in the future are health and safety competence, decision-making, leadership, and problem-solving skills. On the other hand, public-speaking, big data mining, and internet of things were not considered to be critical. These findings indicated that even with technological advancements, skills needed to ensure that projects were delivered successfully included managerial skills. The study sheds more light on skills considered critical at present and which might be relevant in the future. The study signposts the importance of critical skills to an individual and the entire construction industry. Efforts can be made to ensure that relevant critical skills for high output are emphasized and planning can be made for future and predicted construction industry workforce needs.

- 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.

Just to highlight the significance of CI, according to Kayumba (2013: 34), Kumar and Bansal (2013: 34) and Ofori (2012: 5), amongst other functions performed by the CI is to construct the infrastructure and physical structures. CI is a driver of both physical, structural, social and economic developments (Pillay and Haupt, 2016: 374; Idrus, 2011: 1142; Windapo and Cattell, 2013: 65; Kayumba, 2013: 510). CI is deemed critical for economic advancements of South Africa through infrastructure delivery and job creation (Pillay and Haupt, 2016: 374; Windapo and Cattell, 2012: 65). In other words, CI is an enabler in the pursuit of nation vision and aspirations because of its ability to provide infrastructure such as roads, buildings and stadiums and hence, the creation of employment. Conversely, poorly performing CI can affect other industries.

- 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: Sustainable construction practices not only benefits government, environment and occupants but it secure the earth for future generations to come. Thus the paper discussing sustainable construction practices challenges in the construction industry of South Africa. Structured questionnaires were distributed to different construction companies and construction professionals. From the 75 questionnaires distributed, 60 were brought back and they were all valid and usable. Findings from the survey results obtained from the chosen respondents revealed that the is a lack of training in an organization regarding sustainable construction, lack of awareness of sustainable construction practices, lack of sustainable environmental materials, changes in material prices and escalations, lack of accessible guidance, lack of technical skills, resistance to change in adoption and material scarcity. The construction industry needs to promote and create more workshops on sustainable construction practices so that more stake holders would be aware of it benefits and incentives should be provided to organization that are implementing sustainable construction. Furthermore, the implementation of construction principles can be achieved successfully if all the construction stakeholders participates from design to completion of the project with the assistance of knowledgeable project manager on sustainable construction practices. The study will contribute to the body of knowledge by increasing more awareness of SC to professionals in order to be implemented.

- 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: The accelerating decline in the environment and increasing atmospheric concentration of greenhouse gases (GHGs) are closely linked to human activities. This has caused the menace of climate change with the impact globally felt. The continent of Africa, given its geographical location, is believed to be more vulnerable and will severely feel these impacts. To curtail this, mitigation and adaptation have been recognised as the most potent strategies to curtail the challenge of climate change. Increased adaptive capabilities of infrastructures and systems in South Africa is, therefore, imperative. This paper explores biomimicry, a new field that studies and emulates the forms, processes, and strategies found in natural organisms to solve human challenges. For its over 3.8 billion years of evolution, nature has effectively and efficiently tackled many of the challenges mankind is grappling wi th today. Hence, the objective of this study is to evaluate and present existing biomimetic materials and technologies which contribute less to the degradation of the environment. Biomimetic materials and technologies, known to possess sustainable credentials will reduce the release of GHGs and has the potential for carbon sequestration. The result will help offer sustainable alternatives to those materials and products which significantly contribute to the increase in carbon footprint.

- 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: Collaborative practices (CP) in recent times have emerged as a significant requirement and a viable approach to overcome the growing changing business environment and adversarial nature of construction supply chain in construction project delivery globally. This is partly due to the propensity of CP for improving performance and enhancing competitiveness by responding to the changing environment in construction. Even though CP has been rigorously pursued in many advanced areas of the construction industry, its implementation and nature of practices required in the South African construction industry (SACI) are relatively unknown. Additionally, there is a lack of consensus among stakeholders and practitioners on the nature of CP to engender the needed performance towards success in infrastructural delivery in South Africa. By adopting a qualitative design using structured interviews with 31 participants and convergence analysis of multiple case studies, the study revealed on site operational governance and the nature of operational structures and integration strategies adopted for supply chain contributors as the main collaborative practices in the SACI. These findings give empirical credence to the nature of collaborative practices necessary in construction project delivery in South Africa and thus offer practical and theoretical implications for the industry.

- 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.
