Spending the days of the heat with the least strain possible is not only us but also the infrastructure that supports our daily lives.
When mercury beats red and high temperatures are maintained more than the season predicts, in huge projects such as the Athens Metro line, not only measures are taken to protect workers but also for the durability of construction.
The heatwave often strains the metal- mainly- constructions and is a field of testing for their behavior, and therefore engineers take measures to “relieve” them, using various techniques and international standards.
A typical example is that applied to the Library Frear, a small ventilation vent, located opposite the “Academy” station.
This well is based on metal constructions, where temperatures can grow up to 50th, 60th or even 70th Celsius these days. Engineers of the Construction Consortium (AVAX – GHELLA – ALSTOM), having vast experience of such scale projects, apply various techniques of mitigation of metals from the heat. Either by investing these braces with special materials, or even bypassing the metal structures by throwing mercury at tolerable levels.
The state -of -the -art construction standards of line 4 enable the “Hellenic Metro” supervisor engineers to watch real time and oversee, intervening, if necessary, this enormous attempt to withstand the adversity of the heat, in addition to humans, and infrastructures.
Climate change and its effects are now on our life and daily lives. The taking of such measures is mainly imposed by responsibility and preventive care – but also some extraordinary reasons for vigilance – since support materials are designed for almost twice as much as those they receive today in the hot center of Athens.
