My favorite project was the 1947 Constitution Building. I went downtown with a tape measure and collected dimensions of every building part I could reach. Knowing the size of bricks and the thickness of mortar makes calculating upper floor details a breeze!
This also gave me a new set of buildings: Waverly Hills Sanatorium, Merchants Ice Tower, the demolished Baxter Avenue Station, and the Jones-Dabney lab building. Later, I worked on the 1910 Union Station in Gary, IN and the 1909 Terminal Station in Birmingham, AL.
I recently worked on Bernheim Distillery and Bosler's Fireproof Garage in Louisville.
