摘要恶劣天气的影响是造成工程延误、法律的索赔和经济损失的常见原因。最近进行的研究旨在将天气的影响纳入项目规划;但这些研究集中在一组狭窄的天气变量，或非常有限的建筑活动或项目范围内。提出了一种将一个国家的历史气象数据处理成一组具有代表性的标准施工活动的天气延迟图的方法。也就是说，正弦曲线用于将天气变量的每日组合与延迟相关联，并提供预期生产力损失的系数。一个完整的案例研究，包括建设这些地图和相关的正弦波为英国提出沿着与一个例子，他们使用的建筑施工规划。这项研究的结果表明，英国的天气延长项目工期平均21%。然而，在规划时使用来自天气观测的气候数据可以导致项目工期平均缩短16%，间接和管理费用也相应减少。
Abstract The impact of (adverse) weather is a common cause of delays, legal claims and economic losses in construction projects. Research has recently been carried out aimed at incorporating the effect of weather in project planning; but these studies have focussed on either a narrow set of weather variables, or a very limited range of construction activities or projects. A method for processing a country’s historical weather data into a set of weather delay maps for some representative standard construction activities is proposed. Namely, sine curves are used to associate daily combinations of weather variables to delay and provide coefficients for expected productivity losses. A complete case study comprising the construction of these maps and the associated sine waves for the UK is presented along with an example of their use in building construction planning. Findings of this study indicate that UK weather extends project durations by an average of 21%. However, using climatological data derived from weather observations when planning could lead to average reductions in project durations of 16%, with proportional reductions in indirect and overhead costs.
