Assessment of weather events; the combined effects of rainfall and frost

How would a weather event be assessed under NEC4, if the MET Office location based downtime summaries showed that both the 1-in-10 year values for daily rainfall and days of freezing had been exceeded?

Does one take precedence over the other, or are the effects of the combined total number of excess days taken into account when making an assessment?

As with all compensation events, it’s bit stacked in contractors favour i.e. an EVENT occurs for which there could be multiple COMPENSATION event headings. While the Contractor can’t “double charge”, it can notify and quote on the basis of the one which best suits it i.e. has the biggest effect on its Defined Costs. Likewise within the weather compensation event clause for the different types of weather events.
