The new production halls for electric cars are divided up into bodyshops for the MCV vehicle and areas allocated for assembly and logistics. The hall was built in reinforced concrete with isolated solid cores. The hall supports rest on individual foundations and individual clamped foundations. The reinforced concrete walls rest on strip foundations. All floor slabs were made using a white dry-shake surface hardener, surface-finished. Reinforced concrete ice walls were built using reinforced concrete prefabricated components and in-situ concrete.
