In the factory:
   SUNDAYsystem is designed for the prefabrication of wall elements into panels, the complete construction of roof studs and preparation of mid-floors in the factory.

On the building site:
   the prefabricated elements are assembled into the complete structural frame of the building, and the construction is anchored in the foundation. OSB board (waterproof) is used to additionally reinforce the frame.
   After putting all the vertical structure elements together, roof studs and mid-floors are fixed. After all this, the structure is ready for a finish job. It is worth mentioning that since the steel construction is light it is erected manually without the use of heavy construction equipment.
