The first elevator in the United States was installed at Harvard University in 1874. It was not a passenger elevator as we typically think of today, but rather a freight elevator used to move heavy items within a building. The installation of this elevator marked an important development in building technology and transportation within multi-story structures. It was based on the design of Elisha Otis, who is famous for inventing the safety elevator with a safety brake system that prevents the elevator from falling if the hoisting cable fails. Otis’ innovation played a pivotal role in making elevators safe and practical for everyday use, leading to their widespread adoption in buildings around the world.

Education communities are stewards of 100’s of lifts, elevators and moving walks. At the University of Michigan, there are the better part of 1000 of them; with 19 of them in Michigan Stadium alone. The cost of building them — on the order of $50,000 to $150,000 per floor depending upon architectural styling — and the highly trained staff needed to operate, maintain and program interoperability software is another cost that requires attention. All building design and construction disciplines — architectural, mechanical and electrical have a hand in making this technology safe and sustainabile.
We start with international and nationally developed best practice literature and work our way to state level adaptations. Labor for this technology is heavily regulated.
Its a rarefied and crazy domain for the user-interest. Expertise is passionate about safety and idiosyncratic but needs to be given the life safety hazard. Today we review o pull together public consultation notices on relevant codes, standards and regulations today 11 AM/EDT.
