Part one of the Contract Data includes four measurements for which ten year ‘return period statistics’ for each calendar month may be required. They are:

  • The cumulative rainfall (mm) (this includes the equivalent rainfall corresponding to falls of snow),
  • The number of days with rainfall more than 5 mm (a measure of the days when outside work may be interrupted by rain).
  • The number of days with minimum air temperature less than 0 degrees Celsius, and
  • The number of days with snow lying at a stated time GMT (in the UK, Met Office readings are taken at 09:00 hours GMT; the time may vary in other countries).

These measurements have been selected as being the minimum weather aspects which can have a significant effect on construction work in the UK and countries with similar climates.
