- Description: Abstract: The construction industry is increasing in size, technology complexity, interdependencies, and variations in demands from clients. It is of huge significance for an organisation to analyse and identify how well it is performing, and to know the appropriate catalyst that stands to be utilised, to ensure ultimate performance. However, the purpose of this paper is to determine whether there is a difference in the perception of consultants and contractors on the factors affecting the performance of construction projects. The methodology adopted in this research was a quantitative research approach. Data was collected using a questionnaire. The questionnaire aimed at 60 respondents which were civil engineers, quantity surveyors, construction managers, architects, project managers and contractors. Result from the findings revealed that consultants see conformance to specification being more important whereas contractors see, late payment from owner to contractor being more vital.

- 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: 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: Implementation of construction works within the stipulated budget is vital for both the investor and the contractor. Yet construction projects, even those perfectly planned and organised, run the risk of cost overruns. Despite many tools supporting construction management, cost overruns keep occurring in construction projects. The present paper presents the findings of a survey aimed at identifying the most important causes and effects of cost overruns on construction projects in Gauteng - South Mrican construction industry. 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 inadequate planning, change in project design, poor project management, inadequate financial provision and inaccurate estimates were the major causes of cost overruns. Furthermore, the effects of cost overruns were identified to be construction project delays, increase in project cost due to extension on time, liability of companies to bad debt, project abandonment and company insolvency among others. The study contributes to the body of knowledge on the subject of the causes of construction project schedule overruns in Gauteng, South Africa.
