Final section of exterior walls framed out

With the fire proofing of the steel beams complete, the trailer that held the mixing and spraying apparatus has been removed from the site. This allowed for crews to begin framing out the exterior walls on northwest side of the third floor.



This type of framing is called fly-by framing. The framing is moved off of the concrete floor and is attached to the side of the concrete beam using specially designed and engineered clips to attach the metal framing.



The dimples and rectangular stamp design give the clip added strength. All of the exterior walls have been framed out using this fly-by technique.
