In my lifetime, I have seen highways and structures built and age, fall into disrepair, shed their concrete skin, and show their steel bones. Rebar is the backbone of ferro-concrete method of construction. Surrounded by concrete, the tension inherent in the steel holds the concrete in compression adding strength to the static load. The tension is directional. Add energy through gravity, climate, vibration, and the structure expresses itself in ways although characteristic of the material are not reflective of its intended use. I use rebar to explore and discuss the relationship between man and nature, use and reuse, between energy and tension, static and active, between inside and out, container and contained, between moment and time.
