Carnegie Hall is a concert venue in Midtown Manhattan in New York City, NY. Designed by architect William Burnet Tuthill and built by philanthropist Andrew Carnegie in 1891, it is one of the most prestigious venues in the world for both classical music and popular music.
The re-development project involved replacing the existing roof to create a green roof space, adding elevator framing, and removing and adding floors in the North and South Towers. Most of the construction was completed with the venue still operational.
Although we were not an official Design-Assist provider on the project, we created a design-assist atmosphere after the tender award to ensure the best outcome with regard to both finished product and schedule.
We provided detailing and fabrication, as well as surveying and construction services.
Working on an historical building always makes for lots of surprises. As there were no existing drawings, we needed to be flexible in our approach and in many cases, plan on the fly as the building framework became exposed.
As an example, the original building was built in late 1800’s using cast iron columns which meant that we had to connect directly to cast iron.
