- Description: The construction industry is known as a very highly-fragmented industry with a large number of activities involving different parties and professionals such as project managers, architects, engineers, quantity surveyors, contractors, suppliers and financiers. As it is a fragmented industry, management efficiency and competency in the industry is needed to gain a higher level of competitiveness. Although it is often clear what the causes and effects of construction projects delays are, little attention has been given to the role of management in the causes, effects and incidence of construction project delays. This research fills this gap in the literature. For the study, a theoretical framework to investigate the role of management in the causes, effects and incidence of construction project delays was developed. The framework showed how four management functions predicted the causes, effects and incidence of construction project delays. Nine factors were identified as the causes of construction project delays, namely, clients, contractors, labour, equipment, materials, consultants, community, contract and external issues. For the study, three effects of delays were proposed, namely, finance related delays, human related delays and legal related delays. In addition, the incidence of delays included the frequency of delays and duration of delays. This framework was empirically tested, and partial correlations were used to test the four hypotheses of the study. Three of the four hypotheses were accepted while the forth one was only partially-accepted. It was determined that demographics significantly predicted organising and leading of contractor managers in construction project delays. More specifically, demographics influenced how contractors with different educational levels executed organising and leading in managing construction project delays. The results further showed that management functions employed in construction projects, predicted five of the nine causes of construction delays. Further, the causes of construction project delays predicted both frequency and duration representing the incidence of construction delays. Lastly, the causes of construction project delays predicted the financial, human and legal effects of construction delays. The empirically-tested framework produced only two factors causing construction project delays. Factor one included variables relating to contractor and consultant related issues, and factor two included community, contractual and external issues. The factors for the effects of construction project delays and incidence of construction project delays remained the same. Respondent contractors in this study indicated that education was important as it influenced both leadership and organising functions of these contractors. Age, sex and other demographics did not influence the management functions for these contractors. Although much has been written on the causes, effects and incidence of construction project delays, very little attention has focussed on the role of management in these. For the respondent contractors who were included in the research, the two management functions that would influence the causes, effects and incidence of construction project delays, included organising and leadership. It further showed that these contractors were adequately dealing with planning and controlling, but needed to pay attention to organising and leadership.

- Description: Construction delays are a global phenomenon. Factors causing construction delays in construction projects differ from country to country, due to different prevailing conditions. The prevailing conditions that could exert an influence on project delivery time are: political, economic, and physical factors as well as level of technological development; management style, and construction techniques. The construction industry is a major player in the economy, generating both employment and wealth. However, many projects experience extensive delays and thereby exceed initial time and cost estimates. This study aims at determining the causes of delays in project delivery in South Africa; evolving interventions, and developing a model for the delivery of projects on time. Inferential and linear regression statistical tools were used in the analysis of data for the study. The sample population consists of architects, builders, quantity surveyors, structural engineers, and clients, and the metropolitan cities of five provinces constituted the geographical delimitation of the study. The provinces are: Eastern Cape; Free State; Gauteng; KwaZulu-Natal, and Western Cape. The metropolitan cities are: Bloemfontein; Cape Town; Durban; Johannesburg, and Port Elizabeth. Findings which negatively influence project delivery time in South Africa include the following: lack of adequate planning; management style; the lack of constructability reviews of designs; inadequate motivation of workers; economic policies; lack of prompt payment to contractors, and quality of management during design and construction. Recommendations include: (1) The introduction of the following courses in built environment tertiary education � quality management competences; operational planning; design management, and generic management; (2) pre-qualification of suppliers; (3) inclusion of the following in tender documentation � human resource schedule; plant and equipment schedule; quality assurance plan, and work schedule; (4) appointment of materials specialists on a large projects; (5) the model developed should be adopted for use in the South African construction industry for the delivery of projects on time, and (6) the linear regression equation: Y = 13.1159 + 1.1341x or 35.3 percent addition on time for the estimation of project delivery time.
