Dimension | Steel Modular | Traditional |
Speed | Built in factories + on-site in parallel | Site-built sequentially |
Cost Control | Fixed pricing + minimal waste | Frequent changes + material loss |
Precision | Robotic welding, <3mm tolerance | Manual labor, ±15mm tolerance |
Safety | 85% built off-site, safer controlled factories | High-risk open-site construction |
Sustainability | 100% recyclable steel, low emissions | High concrete waste, CO₂ ↑ |
Flexibility | Stackable, scalable, easy to expand | Hard to modify, costly to rebuild |
