BEKKER, M. C.  e  MASHABA, J. T.. A critical review of agricultural related construction project failures at the Department of Agricultural, Rural Development and Environmental Affairs (DARDLEA): Mpumalanga. S Afr. Jnl. Agric. Ext. [online]. 2018, vol.46, n.1, pp.83-91. ISSN 2413-3221.  http://dx.doi.org/10.17159/2413-3221/2018/v46n1a446.

The aim of the study was to determine the causes of construction project failures in the Department of Agriculture, Rural Development and Environmental Affairs (DARDLEA). A detailed literature review was carried out on construction projects that failed due to cost and time overruns. A list of construction project failure factors was identified and later categorised into contractor, client and owner-related causes. A five-point Likert scale was used to collect data from the contractors and owners and the same questionnaire was used to interview the clients or beneficiaries telephonically. The data were analysed using the Relative Importance Index (RII) and Correlation Testing. The key causes of construction project failure as per their rankings were poor communication, lack of monitoring and evaluation, lack of client or beneficiary involvement, lack of project planning, financial difficulties, poor project scheduling, incomplete project drawing, conflict, poor technical performance, and changing client requirements. The Spearman correlation concluded that relationships existed amongst the owner, client and contractor responses. From the results, the main recommendation is that all project planning, design and scheduling should be approved by the contractor, client and owner before construction commences. Secondly, all project stakeholders should be involved during the planning of projects to enhance project sustainability, and thirdly, projects should only commence when there is a guarantee that all plans, budgets and schedules are realistic, and funds are available for access. With regards to extension, the results indicate specific areas of stakeholder engagement prior and during construction to assist in managing expectations.
