My third engineering job (after time off while we moved to New York and I worked for an internet company for a year) was at DCE. I'm still not sure everything was on the up-and-up but I liked my colleagues and working on some projects that were much larger than what I was doing in San Francisco.
Image 1 crossed my path briefly and really only during the construction phase. I did some small design tasks but mainly I checked shop drawings. Which gave me a headache since it is a Frank Gehry design. I did some flat plate design on Astor Place (Image 2). The famous Charles Gwathmey was the design architect and the footprint of the tower portion was that of a grand piano. This will be upper-echelon living on Cooper Square if ever built. The majority of my design work while at this firm was on 181 E 90th (Image 3). I learned a lot about "air rights" (the building cantilevers out over the adjacent properties at the required setback) and construction sequencing concerning the trade unions. There were huge transfer beams (> 6 feet deep) at the cantilevers that were built-up plate girders embedded in concrete. The iron workers and concrete guys were at odds as to who was placing the steel. Very powerful groups and they often control certain elements of the design. I was able to do a few oddball tasks: Image 4 - climb up the Essex House sign and inspect the letters and steel truss, Image 5 - inspect the subway structure underneath a project site. Another project I worked closely on was 1500 Lexington Ave. Although I could not find a picture on the web (that wasn't posted with flash).
