anesthesia is a mixed medium project of concrete, steel, and tempered glass mosaic. Constructed as a performance piece, Anesthesia has (3) aerial performance attachments 20’ from ground, and hosts a performance area atop the elevated slab; aerial equipment isn’t the only art form that can attach to the rigging points, swings, fire pits, cages… the imagination can run wild here. At the top of the project a mounting plate features whatever art or sign the client prefers. The electrical system is a 12v solar system that can operate on a mere 65watts of power… when fully assembled this piece weighs over 8 tons and stretches to a height of 55’. This piece has been reviewed and approved by a California State certified Structural Engineer.
First step in building Anesthesia was forming and pouring the foundation blocks; each block measures 3’ tall x 30” wide x 30” deep. The reinforcing steel cage was built using a #5 bar (0.625”) 6”o.c. The concrete mix is a lightweight 4,000 psi mix and the anchor bolts are 7/8” x 18”. Once the blocks were poured, the electrical trough’s were carved, the lines were placed, and the trough’s were then troweled over with a concrete patch for a seamless concrete surface.
Once the blocks cured a painted design was applied to the surface of the blocks followed by a silicone applied tempered glass mosaic. The mosaic detail on this project is extremely ornate. The glass used varies in thickness, texture, and clarity thus making the painted design even more pronounced and dramatic. The grout includes a poly ad-mix as well as a glitter mix for an added effect. The finished mosaic projects a combination of the painted design underneath as well as the puzzle of broken glass. Each block also has installed (28) LED lights attached with a stainless steel and rubber bezel.
The elevated slab is a 12” thick solid concrete triangle. The measurements are 9’x9’x9’; it is constructed in the same fashion as the foundation blocks using: no.5 rebar, 4,000psi lightweight mix, ¾” anchor bolts, silicone applied glass mosaics, (84) LED lights, poly-grout… The slab has (3) 4” steel sleeve embeds for aerial rigging.
The structural steel on this project is a 10” and 12” pipe with a .365” wall. Featured art for the 2007 showing was a stainless steel and LED light spark
This project was first rendered utilizing three times the concrete and steel; value engineering actually reduced the mass of the piece by 2/3.
