ABSTRACT

Assessment techniques such as cost-benefit analysis are used to evaluate and approve public sector projects and decide among different design alternatives. Therefore, they have a considerable influence on the materiality, performance and reception of infrastructural landscapes. This paper analyses the dynamic interaction of assessment techniques with other forces and modes of knowledge that produce the built environment using the historic case study of the Ayalon Project in Israel. The project transformed a seasonal river into a depressed urban expressway, railroad, and flood control facility. The research opens the ‘black box’ of cost-benefit, multiple-criteria and risk analysis to reconstruct the complex chain of decisions that shaped the regulation canal, whose periodic flooding is regarded as a national scandal. Its main conclusion is that the recursive activation of these portable techniques contributed to the Ayalon’s unstable performance and landscape singularity.

摘要

诸如成本效益分析之类的评估技术用于评估和批准公共部门项目，并在不同的设计方案之间做出决定。因此，它们对基础设施景观的重要性，性能和接受度有很大影响。本文使用以色列Ayalon项目的历史案例研究，分析了评估技术与其他因素和知识模式之间动态的相互作用，这些知识和模式产生了建筑环境。该项目将季节性河流变成了郁闷的城市高速公路，铁路和防洪设施。这项研究打开了成本收益，多准则和风险分析的“黑匣子”，以重建形成监管渠道的复杂决策链，监管渠道的定期洪水被视为国家丑闻。
