By building infrastructure, planners want to exert control over the environment for the sake of society. Due to uncertainty and complexity, such control is always limited and can become contested. Based on a case study of replacing a pumping station, we show how planners can understand the replacement of infrastructure and what informs adequate replacement strategies amid uncertainty. The paper argues that the concepts (un)control and (re)structuring help understand replacements in the context of infrastructure planning. Infrastructure replacements are interventions on different levels which restructure existing systems, asset networks, local areas and assets themselves. Necessary information for developing a replacement strategy, exerted control or uncontrol, possible innovations and restructuring effects differ among these levels. We conclude that planners need to be cognizant that infrastructure replacements, no matter how large or small, restructure both environments and social institutions.

规划基础设施更换：重组和对环境施加部分控制

通过建设基础设施，规划者希望为了社会对环境施加控制。由于不确定性和复杂性，这种控制总是有限的并且可能会引起争议。基于更换泵站的案例研究，我们展示了规划者如何理解基础设施的更换以及在不确定的情况下如何制定适当的更换策略。该论文认为，（取消）控制和（重新）结构的概念有助于理解基础设施规划背景下的替代。基础设施更换是不同层次的干预，重组现有系统、资产网络、本地区域和资产本身。制定替代战略、实施控制或不控制、可能的创新和重组效果的必要信息在这些级别之间有所不同。
