An approach to improve quality in the construction of electrical networks

Abstract

Eskom is embarking on a project that addresses security of supply initiatives, which are live work, high-voltage underground cabling, strategic spares, network planning and design, change management, technical training and contractor development, to strengthen the security and the reliability of the supply chain. This research investigates the causes of poor quality workmanship by the contractors during the construction of network infrastructure. The impact that the contractors have on the network's performance, and the reliability of the supply chain are very important to evaluate, as it is one of the key performance indicators measured for business performance. The quality of workmanship and the best practices that the contractors provide during the construction phase have an impact on the performance of the network, which is why this research will focus on the development of the contractors to improve the quality of workmanship. In the past few years Eskom Distribution Division has experienced numerous electrical faults in the networks, resulting in a loss of power to the customers and loss of revenue to the organisation. Contractor development is one of the methods used to build positive and mutually benefiting relationships between the buyer and the supplier. The method used in this research was through looking at the current practices, from the selection of contractor to development and maintaining of the supplier database. The objectives of the proposed research are to Improve the quality of workmanship of the contractors, Improve the project lead times during construction and investigate contractor development initiatives.
