This paper deals with the technology of performing construction work in extreme weather conditions considering the air temperature, that is, temperatures below 5 ° C or above 30 ° C. The key problems that occur in extreme weather conditions during the construction works are described, including both required preparatory work and execution itself. The paper referred to the example of a bad method of execution at low temperatures, and the consequences thereof. In addition, the use of suitable additives for the fabrication of concrete and asphalt mixtures, which are incorporated at high and low temperatures, along with various coatings required for the high quality protection of wood and steel structures, have been explained.
