An objective and measurable approach was adopted in relation to what is considered to be a weather event which could trigger a delay event, i.e. the contractor gets additional time. A delay event is triggered when a weather event exceeds a defined threshold (90th percentile) value in any given month.
Weather events are:
- Number of days per month with a rainfall amount > 10mm.
- Number of days per month with a maximum 10-min. mean wind speed >=15m/s.
- Number of days per month with a minimum temperature < 0 deg. C.
