Abstract

Throughout Bruce Power’s Unit 1 and 2 Restart Project, discovery work was a challenge and often led to scope expansion. This scope expansion can be broadly categorized as: 1. items that are known to need modification or maintenance, 2. items that can be identified as risks in advance of the project and 3. discovery items that will arise as the project progresses. A systematic approach to addressing this topic is required for any brownfield project and should be applied with equal rigor to outage work. This paper describes the unique challenges and potential mitigation strategies for scope expansion using specific examples from the upgrader refurbishment at Bruce Power.
