  • Description: Abstract: The construction industry has been dealing with drastic changes over the past years, changes that result in a number of negative consequences one of them being job insecurity. These changes concern issues such as increased economic dependency between countries, rapidly changing consumer markets and escalated demands for flexibility within as well as between organisations. However, it is an organisations’ responsibility to manage the changes accordingly to avoid issues such as job insecurity. Hence this paper theoretically discuses job insecurity in the construction industry. The study was conducted with reference to existing theoretical literature, published and unpublished research. The study is mainly a literature review/survey on job insecurity in the construction industry. Literature revealed that employment downsizing, financial crisis, lack of experience and training, technological changes, racism, gender and lack of education were the major causes of job insecurity in the construction industry. The current study is a theoretical assessment of job insecurity in the construction industry and the study contributes to the body of knowledge on the subject of job insecurity in the construction industry.

  • 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 The study is conducted with reference to existing theoretical literature, published and unpublished research.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: 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.

  • 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: Women have a limited advancement in the construction industry due to lack of structured mentorship programme. Mentorship has been used as a tool to advance women in their careers. Previous research has shown that the successful mentorship of women was insufficient. In South Africa the construction industry is currently economically active and has a shortage of qualified and skilled professionals. This paper assesses problems to female graduates’ mentoring in the South African construction industry, recommends measures to promote their mentoring, retention and participation in infrastructure development and examine perceived career barriers of women in entry level and mid-level positions who were formally and informally mentored. The study was mainly a literature review, qualitative with a special focus on women mentoring problems of employees within organizations. The results indicated only one significant finding, informally mentored protégés rated lack of mentoring as more of a barrier to advancement than who reported being formally mentored. The study contributes to social change by providing empirical support for the importance of formal mentoring in empowering women for future career advancement and a guide for policy changes for government and strategies for industry, education and society to solve the problems women graduates experience in South Africa.

  • Description: Abstract: Mentoring is important for all young employees entering the workplace. Despite the growing research on both sets of individuals, mentors and proteges, mentoring from the perspective of the organizational remains comparatively under reported. The purpose of this paper is to investigate the impact of mentoring in the construction industry.Further more it will identify the drawbacks, benefits and examine future prospects of formal mentoring in medium sized and large organisations in South African construction industy. The paper focuses on how organisations view mentoring. The study was mainly a literature review with a special focus on formal mentoring. The data used in the report was mainly qualitative, based on the, case studies and historical data. The review is into formal mentoring of young employees entering the work place. The scope of this review is confined to the literature that discusses formal mentoring internal to the workplace which support on and off job learning. The results revealed the organisation current situation and the issues that are important to the HR function. Mentoring is primarily used to transfer tacit knowledge from those near retirement to younger employees, foster the personel development and create well being at work. Career advancement and work performance are not as impotant as might have been thought. Young employees, in particular may demand the use of social media, along side mentoring.

  • 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: 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: 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,..
