SEQUENTIAL EXCAVATION METHOD (SEM)

The video likely performed well due to the visually engaging and detailed diorama, which offered a satisfying and educational glimpse into a complex engineering process. The use of miniature machinery and realistic simulation of construction activities would have appealed to a broad audience interested in engineering, construction, or even ASMR-like content.

This video showcases a diorama of the Sequential Excavation Method (SEM) for tunnel construction. The detailed model illustrates the process with miniature excavators, drills, and shotcrete application, highlighting geotechnical engineering principles.
