End of Technical Report
After checking the results of the structural tests and engineering calculations for the additional weights (adding two floors), it was found that the structure is
structurally sound. In order to increase the safety factor of the structure, it was decided to add structural reinforcement to the columns and thresholds on the ground
floors and basement (and as indicated in the attached construction plans (25-21 page).) The reinforcement also includes Making cross braces (page - bracing steel cross .)
