With "standardized design, factory production, assembly construction, and information management" as its core, MCC22 has built a complete industrial chain system covering R&D, design, manufacturing, and construction. Through the deep integration of the BIM intelligent construction platform and the smart factory, it has achieved an assembly construction speed of "one floor every two days". Its innovative steel-concrete composite structure technology system for MCC Green Building Materials Engineering & Technology Center reduces carbon emissions by 30% compared to traditional construction, filling a domestic technological gap in fields such as super high-rise buildings and large spans.
