  • Description: Abstract: , Basic services When Cape Town was hit by drought in 2017, Johannesburg dam levels were also been affirmed as low; affecting some parts of Johannesburg areas. Through various projects, Johannesburg city contributed water to the residents of Cape Town at the time of famine. Nonetheless, South Africa being one of the water strained countries; is worsened by the growing inequality among the poor and the rich with the former having the feeling that the later are treated better. The study was piloted in Johannesburg within Johannesburg Metropolitan Municipality (JMM). The population size was sampled from the households within the municipality’s regions namely A, B, C, D, E, F and G. The aim was to assess household’s thoughts in view of service quality offered by the municipality on water supply. Even though the study focused on the efficiency of water supply, the inquiry was limited only to service quality provided to households and not the product quality. Despite the fact that households in this municipality proclaim their satisfaction regarding the quality of supplied water, a majority expressed trepidations about communication breakdown between the municipality and households. People indicated that the municipality does not care about people’s good health and wellbeing. Results show that there are no active engagements between the municipality and households at JMM. Moreover, households at JMM have limited knowledge about water endeavors. For an example, there was a high ambiguously when people were asked their opinions on the accuracy of billing for consumed water, per household. At the time of this study, only 28% of respondents were convinced that billing is in fact accurate; 30% alleged that it is not accurate and a massive percentage of 41% expressed that they are not sure about the level of accuracy where billing is concerned.

  • Description: Abstract: An important process in the procurement of infrastructure is tendering. Tendering involves invitation to submit tender by clients or their representative, submission of required documents by contractors and selection of appropriate contractors to execute the project. This study examines important constituents of tender price submitted by a contractor and factors affecting their tender price in Nigeria with a view to improving their competitiveness and success rate locally and internationally. Using quantitative design approach, data were obtained through questionnaires administered on registered construction professionals and contracting firms with adequate practicing experience. Prior to the study, pilot study was carried out to ensure proper validity and reliability of the instrument. From the final survey, there is no significance difference in the significance, importance and level of contractors' awareness of constituents of tender price. This implies that contractors are conversant of important elements of their tender price but the major factors affecting this price are related to incorrect/incomplete design as well as buildability and technicality associated the project. These factors are more of project characteristics than that of stakeholders and external variables. In view of this, nature and size of projects should be considered as major factors in estimating tender figure of construction projects by contractors. More so, for the contractors to remain in construction business, there is a need for training, innovation and advancement in the use of new and modern technology.

  • Description: Abstract: Construction industry is a major consumer of natural resources and this has a significant impact on the environment and socio-economic development of society. The result of this impact includes deforestation; climate change, air, water and land pollution; and the like. Ecological economics (EE) models are tools for assessing and understanding these issues with a view to enhancing green buildings and sustainable construction in general. As part of a continuous study, this research therefore examines the level of awareness of the concept of EE by construction professionals in a quest to adopting the principle of sustainable development. Data were collected through questionnaires administered on relevant and experienced construction professionals such as construction project managers, architects, engineers, quantity surveyors and construction managers. EE as an aid would help in mitigating construction impacts on the environment, thereby enhancing sustainability but it is barely practised in the construction industry. This is as a result of the fact that construction professionals have little or no knowledge of its existence in the local industry. Most professionals with knowledge of the concept in the study area obtained the information on sustainability through the media and short courses .. The basic influencing factors are related to professionals' levels of education, the economic development of the country and knowledge of the environment. Introducing EE through communicating new ideas to stakeholders (through environmental campaigns, conferences, and the like) as well as incentivising ideas for change relating to greener construction will assist in overcoming the barriers to the adoption of EE in the construction industry. Professionals also need to keep abreast of current sustainable practices, their benefits, challenges, barriers as well as the methods of overcoming these barriers in their quest for delivering sustainable projects.

  • 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: In the era where agencies, parastatals and stakeholders in various sector of the economy around the world are clamoring for sustainable developments that are financially viable, socially harmless and friendly to the environment, it is of note that globalization has played a great role and will continue to do now and in the future. A major stakeholders to the actualization of sustainable infrastructural development are quantity surveyors. This study investigates the impacts of globalization on quantity surveying (QS) practice in Nigeria in the quest of equipping quantity surveyor to contribute positively to sustainability of infrastructure projects. Data were obtained from quantity surveyors (QSs) practicing in quantity surveying firms (QSFs) that are registered and licensed to operate by the Nigerian Institute of Quantity Surveyors (NIQS) in the study area. Compare to the benchmark of importance level, it was observed that level of awareness of quantity surveyors of the six basic elements of globalization is low. It was also observed that international trade, foreign direct investment and capital market flow are basic measures of globalization affecting the practice. These have resulted in increase in clients' demand, more opportunities for QSFs including participation in international projects, rise in usage of ICT and general development of the firms. It is therefore imperative for government, NIQS and Quantity Surveyors Registration Board of Nigeria (QSRBN) to formulate appropriate industrial and trade policies that will foster the competitiveness of QSFs, to enjoy emerging global opportunities and compete adequately without resorting to protective measures.

  • 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: Despite the introduction and adoption of various techniques and innovative practices geared towards improving the delivery of construction projects, some notable problems of cost overrun, time delay, low quality, dissatisfied clients, etc. still persist. One of the notable practices in the construction industry is the use of bonds and guarantees. Construction bond was introduced as an instrument to protect or indemnify its recipients against risks and problems associated with construction projects but the challenge over the years lies in the practical enforcement of bonding conditions and its overall benefits to the construction industry. This research therefore evaluate the risks that are associated with bonded and unbonded projects with a view to ascertaining their effects on overall construction projects success. Primary data were collected through administration of questionnaires on identified construction bond stakeholders namely: clients of public projects: quantity surveying and architectural firms; and construction firms. Questionnaires were administered on 337 respondents out of which 242 were returned while 236 were certified fit for analysis. Mean item score was used for ranking the identified factors while Kruskal-Wallis and Mann-Whitney tests were employed to examine relationship and differences in sample means of different groups of respondents respectively. The study revealed that financial soundness of the issuer also known as credit risk has major effect on projects with bond while for projects without bond, liquidity risk requires the most attention. The identified bond risks are more inherent in bonded projects except for liquidity and volatility risk. In view of this, special attention should be accorded the activities of guarantors, that is banks and insurance companies, shouldered with the responsibilities of issuing bonds in an attempt to reduce their influence on construction bond process. This will enhance value for money for contractors seeking the bonds and eventually lead to success of construction project.

  • Description: Abstract: For clients, owners and financiers of construction projects, construction process signify a huge capital investment which translate into substantial fixed costs for their organizations. Value Management (VM) is a business strategy tool to ascertain whether construction of a facility will provide best function at the lowest possible cost. This study examines the contribution of value management to construction projects with a view to assessing challenges and measures to improve adoption and application of the discipline. Primary data were collected through well-structured questionnaires administered on construction professionals within the study area and Mean Item Score was used for data analysis. The major contributions of VM to the South African construction industry include optimize value for money, creates a clearer focus on the project objectives and works towards arriving at a more effective design. However, poor communication, lack of interaction and unwillingness of clients to pay for VM service, were the challenges affecting the adoption of VM. In order to improve construction project performance using the process of value management, orientation meetings should be duly organised, team structure should be finalised and team members must be appropriately selected for construction projects. Built environment professionals - including construction and project managers, should familiarize themselves with VM and strive for its full adoption and implementation for construction projects in order to achieve best value at the lowest complete life cycle project cost for construction clients.

  • Description: Abstract: Construction is an important aspect of any economy and its effect cannot be over-emphasized. This research investigates the utilisation of lean construction (LC) tools in achieving project processes in the construction industry by identifying its drivers, barriers and how it can improve the delivery of construction projects. The data for the study was collected through detailed questionnaires which were administered on construction role players that are registered and with their professional bodies. The benefits of lean construction includes waste reduction, improved communication system, improved flow and productivity, customer focus and employee empowerment, sharing of knowledge. From the results of the analysis of data obtained from respondents, extensive use of unskilled labour, poor communication, human attitude towards change, lack of interest from clients, lack of client and supplier involvement, lack of long term commitment to change, lack of supply chain integration, lack of technical skills, and inadequate exposure to the requirements of lean construction, were some of the major barriers associated with the implementation of lean construction in the industry. The following lean construction principles that can be used to improve the delivery of construction projects were also identified: business process engineering, team work innovation, ongoing performance management, flow of activities and materials, continuous improvement, elimination of irrelevant activities, team and value management as well as continuous skill development. Itis necessary for organisations to implement the principle of lean construction and such need to be aware of the challenges associated with the practice. More so, there has to be an adequate level of awareness, commitment, knowledge and understanding of the underlying concepts of lean construction to enhance its successful implementation.

  • Description: Abstract: Poor performance of construction projects is one of the major cause for concern in the construction industry. Many of the construction projects executed in Nigeria experienced several challenges ranging from simple to complex issues. This paper therefore, examines factors affecting the performance of construction projects, their effects on the economic development and the impact of the factors on the economic development of the nation. The study identified a set of factors believed to affect project performance through extensive review of literature which form the basis for questionnaire survey. A total of 200 questionnaires were self-administered to professionals in the Nigerian construction industry, out of which 148 were retrieved and considered fit for analysis. The survey findings indicate that the most important factors affecting project performance are: project design cost, project complexity, unavailability of resources, quality of equipment and raw materials, while ontime completion, client satisfaction and productivity were considered to be the main measures of construction project performances. Improvement in technology and extension of infrastructures, were the most important indices of economic development. It is recommended that project owners must work collaboratively with all the professionals involved in carrying out construction project in order to facilitate good performance. More so, stakeholders in the construction industry including professionals and regulatory bodies should be proactive in discharging their responsibilities bearing in mind the effect of construction project performance on economic development of the country.

  • Description: Abstract: Organisations are established to address a particular issue of the society and their success or failure in achieving their set goals and objectives largely depend on both external and internal factors. Inthis study, sources of failure of small and medium businesses in the construction industry were examined and remedies that can be implemented to reduce the failures were evaluated. Data for the study were collected through administration of structured questionnaire on owners of small and medium construction companies. Itwas revealed that the major causes of small business failure are lack of financial managerial ability and general administration of the business. Challenges faced by these firms include inadequate managerial skills and planning, lack of access to work opportunities, prolonged economic recession, lack of financial skills, competition, incompetent employees and lack of basic business, technical and pricing skills. Small construction businesses need to be supported by government and other stakeholders in order for them to be sustainable and this will also guarantee job security for construction professionals and other form of workforce employed in the companies. The managers and directors of these firms should attend and participate in conferences, workshops, seminars and other forms of leadership meetings within and outside the country to improve their leadership, business and organisation skills.
