- 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. This paper assesses the effects of construction projects schedule overruns in the Gauteng – South African 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 extension of time, cost overruns, loss of profit, disputes, poor quality of work due to hurrying the project, creates stress to the client, acceleration losses, bad reputation with contraction team, claims and delay in getting profit by the client were the major effects of construction projects schedule overruns in Gauteng, South Africa. The study contributes to the body of knowledge on the subject of the effects of construction project schedule overruns in Gauteng, South Africa.

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: 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.

- 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.
