• Excellent quality and constructability due to modularized factory production methods and ease of construction after assembly and installation through concrete batch placement
• Maximization of structural safety against internal and external forces through steel connection between RC and PC structures and integration of steel structure by placement of foundation and topping concrete
• Acquisition of design safety, durability and earthquake resistance through structural review
• Removal of pollution sources by omitting temporary support structures and casts
• Enabling perfect inner and outer waterproofing for maintenance
