Advantages Advantages of Modularized of Modularized ConstructionConstruction
Progress Perspective: The fabrication and assembly of modules could beProgress Perspective: The fabrication and assembly of modules could be performed outside of NI and in parallel with the civil construction inside NI, which accelerates the construction progress.
Quality Perspective: Modules are fabricated in specialized fab-shops off site and assembled on site assembly area, which facilitates quality control.
HSE and Housekeeping Perspective: The prefabrication and assembly of modules are done outside of the NI, which reduces the work quantity on NI site and is b fi i l f f d h k ibeneficial for safety and housekeeping management.

Prerequisite of Modularized ConstructionPrerequisite of Modularized Construction
The key prerequisite to achieve modularized construction is the matching between module fabrication and site construction logic, i.e., the design andbetween module fabrication and site construction logic, i.e., the design and fabrication of modules must meet the need of site construction.
