  • Description: Abstract: Performance of construction projects is an issue of concern, not only to contractors and professionals, but other stakeholders including clients, project sponsors and end-users. This is due to complexity of construction process, innovation in the use of raw materials and machinery, new construction management techniques and more importantly, variation in requirement from clients. Thus, this research evaluates factors affecting performance of construction projects from the perspective of consultants and contractors, in order to enhance the quest of the construction industry in contributing positively to the growth of economies. Using quantitative approach, data were collected through close-ended questionnaires administered on a group of learned and experienced consultants and contractors who are based within the study area. From the analysed data, there is a significant difference in the perceptions of consultants and contractors regarding factors affecting performance of construction projects. To consultants, general time factors and conformance to specification are the most important performance indicator for project success while from contractors' view, cost factors including delay in payment from owner to contractor is a major critical success factor. The two groups unilaterally agreed that bringing about the best planning and scheduling technique before and during construction would assist in improving performance of construction projects in the country.

  • Description: Residents’ satisfaction with the building quality and housing condition features has received an increasing recognition as a significant factor which influences the occupants’ satisfaction with their housing units. This paper reports the use of Structural Equation Modelling technique to test the influence of building quality features as a predictor of residents’ satisfaction. The study was conducted amongst South Africa housing practitioners’ and the low-income housing occupants’. Data used in the study were obtained from a Delphi and field questionnaire study. Primary data were collected by a face-to-face administered questionnaire survey conducted among 751 low-income housing residents’ in three metropolitan and one district municipality in the Gauteng Province of South Africa. Data gathered via the questionnaire survey were analysed using structural equation modelling (SEM) which was used to assess the factorial structure of the constructs. Using Structural Equation Modelling software - EQS version 6.2, the factorial structure, reliability and validity of building quality features indicator variables were investigated. The statistical results support the research hypothesised positive relationship that building quality feature has a direct influence in predicting residents’ satisfaction with their houses. Also, the influence of building quality feature on residents’ satisfaction was statistically significant. Further SEM analysis revealed that the Rho and the Cronbach’s alpha coefficients of internal consistency were over 0.70 criterions for acceptability, and the constructs shows a good mode fit to the sample data. The Z-statistics analysis also revealed that the constructs have direct influence in determining low-income residents’ satisfaction with their houses. The result advocates a practical consideration of these construct in future development of subsidised low-income housing in South Africa.

  • Description: The purpose of this paper is to present findings from an investigation conducted in South Africa subsidised low-income housing, on how beneficiary’s participation could influence residents’ satisfaction with their houses. The study was conducted amongst South Africa housing practitioners’ and the low-income housing occupants’. Data used in the study was obtained from a Delphi and field questionnaire study. Using Structural Equation Modelling software EQS, the influence of beneficiaries’ participation was investigated. The finding was that beneficiary participation influence on the residents’ satisfaction was statistically significant and hence exacted a direct influence in the prediction of the residents’ satisfaction with their houses. The research was conducted in South Africa three metropolitan and one district municipalities. Therefore due to the idiosyncratic dataset used in the study, it remains to be seen if the evaluated relationships between beneficiary participation and residents’ satisfaction can replicate to other cross-cultural datasets. If this is the case, the paper makes a significant contribution towards understanding residential satisfaction on subsidised low-income housing projects. This study provided significant insight into how beneficiary participation influence residents’ satisfaction and how residents’ satisfaction with their houses could be improved.

  • Description: Abstract: The complexity, uncertainty, long-duration and the involvement of the sequential tasks and relationships of participants in/of the construction projects render this category of projects prone to variations along their progress. Variations create extra work, time, and money for the construction projects and they vary from one project to another. This paper investigates the impacts of variation orders on public sector projects in South Africa. To achieve the objectives of the study, a critical review of literature was done coupled with questionnaire survey to collect information on possible impacts of variations on the public projects in SA. Through the review of literature 7 major possible impacts of variation orders were identified which provided the basis for the formulation of the questionnaire. The questionnaire was distributed to professionals who work for companies that undertake public construction projects in South Africa. Targeted number of respondents was 50; however a total number of 70 questionnaires were sent out to make up for the cases were respondents did not return questionnaires. Overall, 50 questionnaires were returned and after a careful examination of the received questionnaires only 39 were usable. These formed the basis of the analysis for the study, since it accounts for 78% of the initial sample. Findings revealed that variation orders have major impact on i) time overruns, ii) cost overruns, iii) quality standard enhanced, iv) disputes amongst parties to the contract, and v) productivity degradation, iv) complaints of one or more parties to the contract. It was further noted from the results that variation orders rarely affected health and safety aspect of the public construction projects since all the factors relating to health and safety were the lowest ranked; health and safety degradation, additional health and safety officials, additional health and safety equipment. However, this results are in disagreement with the results on the critical determinants of variation orders on SA public sector construction projects because health and safety conditions was ranked the highest reason for variation orders under other related reasons for variation orders. What these findings mean is that safety considerations may be the reason to cause variation orders but variation orders do not affect health and safety on the construction project.

  • Description: Abstract: This study presents a review of literature relating to leadership styles in the construction industry, with the specific aim of identifying the best suited leadership style in the construction industry. The research objective was necessitated because of the vital role of leadership in achieving organizational goals and the promotion of individual professional’s achievement. To this end, leadership has been widely covered in management/ business school, however, little attention has been given to managerial and leadership behaviour or styles of leaders in the construction industry. The study is conducted with reference to existing theoretical literature, published and unpublished research. This study is mainly a literature review on leadership in the construction industry. One of the primary findings emanating from the study reveals that there are a number of leadership styles available to construction professional. However, for the construction industry and for the managers to be effective they must be able to identify and apply the necessary leadership style suitable for the given situation. Moreover, they should be able to adapt to changes and sometimes contradictory circumstances in which they need to show versatility and flexibility. The study explores leadership and leadership styles in the construction industry and it further highlight’s the theoretical literature with regard to leadership. The study presents a robust background on the leadership styles of construction project leaders.

  • Description: Abstract: Building Information Modelling (BIM) is a concept that has been defined as a technology that digitally constructs an accurate virtual model of a building. BIM can be defined as an IT enabled approach that involves the application and maintenance of a fundamental digital representation of a building and all its information throughout the different stages of the project. This study assesses the ways to overcome the barriers hindering the adoption and implementation of BIM in the South African construction industry. The data used in this paper were derived from primary and secondary sources. The primary data tool (questionnaires), was designed based on the related literature that were reviewed. The questionnaire was distributed to construction professionals in the South Africa construction industry, facility managers, and academics who have are scholars on BIM in the South African construction industry. The questionnaires were analysed using descriptive statistical procedures. The findings revealed that a lack of skills, education, and knowledge of BIM are the biggest barriers to the adaptation and implementation of BIM in South Africa. Furthermore, the results also show that educational and skill development initiatives are widely considered to being the answer to the existing barriers to BIM adoption. Lastly, the study makes some recommendation on feasible ways of moving away from the common practice of construction process and to the adoption of BIM on construction projects in South Africa.

  • Description: Abstract: Poor construction waste management is one of the major causes of project failure in the construction industry and one of the ways of mitigating the challenge is through the use of lean management (LM). This study examines the use of LM to enhance effective productivity in the South African construction industry. 60 well-structured questionnaires were administered on construction professionals such as architects, quantity surveyors, civil engineers, project manager and construction manager out of which 42 were retrieved. Lean management mostly focused on adding value to the product as well as reducing waste in time of things in cycle, it also reduce waste of time through effective time management as well as reduce waste of materials and energy. This indicated that with lean management, everyone becomes a thinker and a creator of something. These requirements are known as willingness to change and the potential self-disapproval. If fully implemented, LM will enhance better construction productivity through reduced inventory, less process waste, just in time delivery, minimize inventory, the use of adequate equipment, encourage collaboration, improve teamwork, improve construction productivity, improve leadership skills and improve labour flow reliability. It was further revealed that the main significant aspect that lean management evolve around is culture, because the culture of lean is subjected on workers being entirely involved and accepted to practice the lean application in common trainings as well as their tasks. It is therefore necessary for construction organizations and concerned parties to improve level of awareness of construction stakeholders especially construction workers on lean management system through workshops, advertisement, training, etc. This will not only aid better productivity in the industry but will also ensure that clients are provided value for their money.

  • 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: Over the past many years, the construction industry has demonstrated reluctance to embrace change towards its conventional ways of doing business. With an economic force generated by a technology moving as rapidly as that of the computer, change is inevitable. Hence, there is a need to identify measures that need to be considered for the effective implementation of Building information modelling (BIM) and Enterprise resource planning (ERP), two construction software's that are meant to help with timely delivery of construction projects. Therefore, this paper investigates the critical success factors that should be considered for the successful implementation of an integrated BIM and ERP systems in the South African construction industry. The investigation was done by identifying from literature factors which are considered critical for the successful implementation of these software's. Thereafter, the identified factors were further confirmed through a quantitative survey conducted amongst professionals working in private sector construction firms engaged in projects ranging from building to civil engineering projects in the South African construction industry. Selected findings reveal that the factors regarded as critical for the successful implementation of a BIM and ERP hybrid include a competent implementation team, sufficient support from top management, infrastructure availability, and competent staff training and human resource among others. Although the findings are based on the perceptions of construction professionals in the South African construction -particularly the Gauteng Province, but the findings supports the knowledge regarding the successful implementation of an integrated BIM and ERP system in the South African construction industry.
