The penetration holes in the precast will be used to support the glass canopy mounted two feet away from the precast. The projection booth will extend out from the sphere through the large square opening. Notice the color of the shoring towers, it indicates the amount of load they can carry. .

Concrete Vs. Wood

Changing building codes is one reason for this.
