Winter construction temperature standard
The outdoor daily average temperature has been stable below 5 degrees Celsius for five consecutive days.
When the daily average outdoor temperature is steadily lower than 5 degrees Celsius for 5 consecutive days, winter construction should be started. This is because the moisture in soil, concrete, mortar and other building materials will freeze at low temperature, which will lead to brittle cracking of materials and bring difficulties to construction and safety.
