Latour and Emilie Hermant made a multimedia companion to Reassembling the Social called Paris: Invisible City which offers a tour of Paris, but not of the common structures and tourist destinations - instead, the typically "invisible" services, objects, and actions that keep the city running. 

I bring this up because it helps explain what I am trying to do here in Boulder with the Engineering Center Building - tracing out the typically "invisible" work done by the creators, designers, administrators, students, faculty, staff, janitors, generators, transformers, HVAC systems, and more that keep the structure intact, viable, and persisting through many generations of graduating students.
