The site is unknown at the time of perceiving this target, but it is related to Helene Grimaud’s project to play the piano in a water-filled structure, where music will bounce off between the arched metallic ceiling and the water surface that had to be absolutely level. So, [A] is my father [archetype of facilities construction inspector role] sitting on a man-made wood pile of the compressed board and a worker approaches him [B] but he is eating a cake rather than  working. My father, then jumps off the wood pile and climbs up like a monkey without safety equipment to inspect metallic piping already installed but not functioning yet. The work practice felt unsafe! My father then discovered a jackknife with various size marking tools. ===== When new information was released on this project I discovered the site, and the engineering involved to create such an environment. Very interesting to say the least. 12/10/2013
