  • Description: Abstract: Construction schedule overruns are not uncommon on construction projects world over and the South African construction industry has not escaped the challenges of failing to deliver projects on time. In order to find mitigation measures of schedule overruns, the first step is to identify the causes of these overruns. Therefore, this paper assesses the causes of construction projects schedule overruns in the South African construction industry, a case of the Gauteng Province. The data used in this paper were derived from both primary and secondary sources. The secondary data was collected via a detailed review of related literature. The primary data was collected through a well-structured questionnaire which was distributed to construction professionals, who include: Architects, quantity surveyors, civil engineers, construction mangers and project managers. Out of the 200 questionnaires sent out, 146 were received back representing a 73% response rate. Data received from the questionnaires was analysed using descriptive statistics procedures. Findings from the study revealed that slowness in decision making process, reworks due to errors during construction, delay in approving major changes in the scope of work, delay in material delivery, shortage of skilled equipment operators, low productivity level of workers, delay in obtaining permits from municipalities and workers risky behaviour on sites were the major causes of construction projects schedule overruns in Gauteng, South Africa. The study contributes to the body of knowledge on the subject of the causes of construction project schedule overruns in Gauteng, South Africa.

  • 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. The model of the building, which will be in 3D, will depict the exact dimensions of the building. The study assesses the barriers to the adoption and implementation of BIM within the South African construction industry, and suggests ways of overcoming the identified barriers to the full adoption and implementation of BIM in the South African construction industry. The data used in this paper was derived from primary and secondary sources. The primary data being questionnaires, was designed based on the related literature that was reviewed. The questionnaire was distributed to construction professionals such as Construction Project Managers, Architects, Quantity Surveyors, Construction Managers, Facility Managers, or academics who have previously done research 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 on BIM are the biggest barriers to the full 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. As well as, establishing feasible ways of moving away from the common practice into using BIM on all construction projects.

  • Description: The efficient municipal service delivery, expectations and perceptions of citizens are one of the important issues which are central to any municipality across various parts of the world. Among these issues, the transparency and accountability, management of funds for local development attracts special interest among citizens, organization, NGOs, and other stakeholders involved in the development process. The vicious cycle of financial constraints and poor service delivery often results into diversion of funds from earmarked development areas to the areas demanding priority attention. These issues still remain unaddressed and hidden in the absence of appropriate transparent and open government accessibility at internal as well as external levels within the municipal context. The paper highlights key findings from selected metropolitan cities of South Africa and India by doing exploratory comparative analysis about to what extent are the municipal websites addressing the issues of transparent and open governance. The assessment of municipal websites is focused on the issues of access to information on development funds and projects at local level to citizens and other stakeholders. The web content analysis on selected cities provide a background for discussion on the areas of concern to address the key gaps and initiatives for enabling transparent and open governance through municipal websites.

  • Description: The construction industry is vital to the existence of other industrial sector and provides the environment under which other sectors operate. It is the largest industry and contributes about 10% of the gross national product (GNP) in industrial-ized countries. It also plays a major role in development and reaching the goals of society. The current study aims to establish the factors required in the manage-ment of good site management on construction sites in Swaziland. The study is conducted with reference to existing theoretical literature, published and un-published research. The study is mainly a literature review/survey on site man-agement practices on construction sites. Findings emanating from the study reveal that realistic studies have identified a number of problems on site management practices such as management and administration problems, technical problems and communication problems. It also indicates that site management involves a mixture of activities which turn basic sources to a finished product. The study presents a strong background on site management practices on construction sites in the Swaziland construction industry.

  • Description: Abstract: South Africa is confronted with huge infrastructure service delivery backlogs, which has a negative impact on the country’s economic growth and improvement of the lives of its citizens. The infrastructural backlog cannot be sufficiently addressed by government alone, as it requires a collaborative effort from both the public (government) and private (business) sectors. The study examined the contribution made by Private Public Partnerships (PPPs) in delivering infrastructure projects. The data used for the study were derived from both primary and secondary sources. The secondary sources were review of literature and primary data were obtained through the use of structured questionnaires which were distributed to construction stakeholders in the public and private sectors, who were involved in the PPP’s projects in South Africa in the Gauteng province. A total of 90 questionnaire were distributed and 80 came back and used for the study. The study revealed that: PPPs speed up the infrastructural projects; completes the infrastructure projects much quicker than the traditional method; PPP increase the effectiveness of projects; completes work on time or even ahead of schedule; greater cost transparency; cost savings; reduction of life-cycle maintenance costs; reduction of the service delivery backlog, etc. The research has revealed that the projects delivered through PPP are of great quality and they are maintained well.

  • 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: 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: Abstract: Studies have revealed that stakeholder management and sustainable principles consideration are essentials for mega construction project success. The aim of this paper was necessitated by the fact that though there is stakeholder dissatisfaction and lack of studies on the sustainability of the Aiport City Project (ACP) Accra, there is a proposal for second phase development. This paper evaluates stakeholders’ and sustainability measures considered for the ACP’s long term sustainability. A mixed method approach and purposive sampling was adopted. The 70% quantitative survey response rate was validated using six (6) semi-structured interviews and data analysed using a descriptive survey method. Key findings indicate that peer review of designs, project stakeholder meetings, project approval in principles and development monitoring were the measures instituted for stakeholder and sustainability considerations rather than the entire stakeholder management process. The research concludes that the ACP is only medium term sustainable due to low level stakeholder consideration, services infrastructure development, high vehicular traffic congestion, high rental values, socio-economic and cultural factors which are challenges for long term project sustainability.

  • Description: Abstract: Effective and formal stakeholder management process is critical in achieving stakeholder needs and satisfaction, an important project success factor. Developed countries construction industries have embraced stakeholder management as a soft project management skill and consequently developed suitable approaches for improved project delivery though developing countries are yet. Studies have associated project failures to poor stakeholders' performance, the absence of formal stakeholder management process, industry challenges and lack of proper documentation in developing countries such as Ghana. This study identifies, reviews and documents the historical development of stakeholder management process in Ghana as part of a broader study aimed at "developing sustainable stakeholder management framework for construction process in developing countries" for enhanced project success. An exploratory method with the qualitative technique was adopted. A literature review was conducted into stakeholder management practice to explore the trend, influence of historical development and documentation of stakeholder management process in relation to industry challenges using three countries as case studies. This is aimed at documenting and developing sustainable stakeholder management process for developing countries. A descriptive survey was used for analysis and documentation. Findings are that formal documentation of industry practices, procurement challenges, stakeholders role in project failures led to the reviews and stakeholder focused reports which that advocated for collaboration. A trend which has influenced the development of stakeholder management process. In the absence of formal documentation, the study identified and documented stakeholder management historical development trend in Ghana for the development of a stakeholder management framework.
