The earthquake has reduced it to a mountain of twisted rebar and shattered concrete, dwarfing the hundreds of rescue workers scurrying around it.

“I never knew so much about concrete and rebar.”

Tesla also constructed an open-air structure outside its main Fremont vehicle facilities in an effort to speed up assembly and production of its Model 3 sedan, but in 2019 was hit with fines from Cal/OSHA for safety violations, including a failure to obtain a permit to the build the open-air facility, failure to protect workers from exposed metal rods and rebar that posed risks and failure to properly train employees to prevent heat illness.

That was just doable with steel, but more specious when it came to protecting beer cans, construction rebar, and Pennsylvania votes.

The hefty concrete walls reinforced with steel rebar as thick as a human arm safely distribute the forces throughout the structure to prevent critical cracks or collapses.
