Abstract
Time extensions can be granted to contractors for unforeseen inclement weather conditions. Inclement weather, as defined in typical construction contracts however, do not typically provide clear definitions of foreseeability and unforeseeability. This creates a range of speculation and interpretation with respect to weather analysis for time extensions. This article identifies significant issues that cause disagreements for weather related time extensions. The issues are to differentiate between usual and unusual weather, establish thresholds for weather parameters, determine timeframe for inclement weather analysis, define the type of construction operations scheduled, measure lingering effects, refine the definition of lost days, account for delays caused by inefficiencies because of unforeseen inclement weather, and incorporate the seasonal weighting of days to convert from work days to calendar days. Contracts should take into consideration these issues to properly facilitate equitable and undisputable extensions of time for inclement weather. [PUBLICATION ABSTRACT]
