Ensuring the safety and sustainability of a manufacturing facility is vital before it is put into operation. This paper presents the results of the Quality Inspection of the Sunvigor Smart Toys workshop, a mandatory technical procedure to comprehensively assess the structural condition. The inspection process was carried out in detail, focusing on core items including: foundation, floor, columns, trusses, purlins, walls, roofing sheets and steel frame system. The purpose is to verify compliance with current technical standards, thereby affirming the load-bearing safety and ability to meet the long-term use requirements of the Sunvigor workshop building.
