The Empire State Building one of the most famous buildings in the entire world. This building has always been extremely interesting to me due to the insane speed the building was built in. The 102 story building was built in just one year and to this day no other building has every been constructed at this speed. It has positively impacted me because, it has grown my love for the concept of lean construction. I have spent several hours researching this building trying to understand why people have not been able to replicate the production levels of this building. It is my belief that increased safety and environmental regulations along with the increased complexity in electrical systems in modern buildings prevents contractors from matching this production level.
