Above the 8th floor slab cutout has been completed. All cables were found and new anchorages were created. These cables were then restressed. Here shoring can be seen going all the way from the 7th floor up to and supporting the bottom of the 9th floor slab, which at the time was undergoing demolition.

Above are the four supports for the bottom of the massive steel frame that will support the glass stairs. There are four anchors in total and each anchor was secured to the slab with a one-half inch embed that went down five inches. Each embed had to be cleared so that no Post Tension cables were damaged in the operation. Many times due to the cable layout the steel company had to modify their base-plates in so that no PT cables were damaged.

Here is a view looking up from the 7th floor up to the 8th floor through the newly created stairwell cutout. The Post-Tensioned cables in both the 8th and 9th floor slabs had a very complex layout. But Digital Concrete had the experience and resources to map out all of the cables. In addition we also provide all scanning for the several hundred other cores that were required on this massive project. Soon the stairway will be finished, complete with sandblasted glass treads.
