VARIATION ORDERS DURING EXECUTION OF CONSTRUCTION INFRASTRUCTURE PROJECTS: CASE STUDY OF AN ELECTRICITY COMPANY

Abstract

Electricity plays a fundamental role in efforts towards sustainable development and poverty alleviation. The South African government resolved to build new power-generating plants, but the completion of these projects has been affected by different variation orders. An investigation was conducted using the compensation events and variation committee records from different stations in the SAP database to determine the trend of the variation orders that were raised during the execution of the new stations and at existing plants. The results showed that factors such as scope change, integration between packages, design errors, and expedited schedules contributed to the variation orders during the execution of the infrastructure projects.
