I think my most memorable project is the lighting of the Jefferson National Expansion Memorial Arch in St. Louis — not only because I live and work in St. Louis, but mostly because of the lesser known things about the project. It was a design that had never been thought technically possible before, so in terms of surmounting a challenge it was probably one of the most important aspects of what we did.
Later, it would open up some other incredible opportunities around the world for us. It was, at the time, the most intently we had ever dealt with the impact of lighting on the environment— indigenous water fowl, migrating birds, atmospheric light scatter—and how to balance those issues with the desire to light structures like the Arch in large scales urban environments. Being able to design projects that not only satisfy clients but serve society as a whole is important, which includes considering how light impacts other aspects of the environment.
In lighting the St. Louis Arch we dealt with a lot of those issues, making the project particularly challenging, but also endlessly fascinating. Successfully completing this project gave me great satisfaction.
