Marc Mimram discusses his architectural engineering projects. He proposes space is a material and discusses the relation of structural members in space and continuity. He shows the design of a roadway and toll booth and describes the construction of its steel forms and talks about “catching the light inside the structure.” Mimram highlights the design of a 150-foot-high light tower, and a high voltage electric tower. He speaks about the void and feeling gravity in his work and the connection to the horizon line. He talks about how the structural void gives his work rigidity.
