ABSTRACT

Major projects, in sectors such as transport, energy, minerals and water, have long life cycles and can have significant local and regional environmental and socio-economic impacts. The impacts of the construction stage can be particularly damaging, if not managed well. Environmental Impact Assessment (EIA) seeks to anticipate such impacts, mitigate adverse and enhance positive impacts through design innovations and associated conditions. However, the approach is only as good as the implementation of such innovations and conditions. The issue of monitoring and auditing of actual, as against predicted, impacts is an Achilles heel in the planning and assessment process. Hinkley Point C (HPC) nuclear power station in the UK is currently one of the largest construction projects in Europe. A recent study of the live project provides a unique insight into the actual local impacts of the early construction years, and appropriate methods of assessment. It identifies KPIs, examines monitoring data, and audits findings against the predictions. The results show varying performance across key impact sectors. Explanations of differences are set out, together with recommendations for improving monitoring and auditing practice.

抽象的

运输，能源，矿产和水等部门的重大项目的生命周期较长，并且可能对当地和地区的环境和社会经济产生重大影响。如果管理不善，施工阶段的影响可能尤其有害。环境影响评估（EIA）力求通过设计创新和相关条件来预测此类影响，减轻不利影响并增强正面影响。但是，该方法仅与实施此类创新和条件一样好。在计划和评估过程中，对实际影响（与预期影响相比）的监视和审计是一个致命弱点。英国的欣克利角C（HPC）核电站目前是欧洲最大的建筑项目之一。最近对现场项目的研究提供了独特的见解，可了解早期施工年份对当地的实际影响以及适当的评估方法。它可以识别KPI，检查监视数据并根据预测审核发现。结果表明，关键影响领域的表现各不相同。陈述了差异的解释，并提出了改进监控和审计实践的建议。
