We cantilevered the framing from the remnants of a support frame which originally supported a 250ft TV Antenna.
The truss framing was required to be constructed of steel pieces which could be shipped on a small boat and erected by hand.

I had the pleasure of meeting with Kevin on occasions when working on a renovation project at the Metropolitan Museum of Art in 2000 to 2002.
Kevin was generous with his time and provided me with some insights on several of his projects.
