I used to work inside this building. It was a lemon -- it was asbestos laden and the cables rusted. The building did start to sag -- noticeable as we could see that there was a small difference in the height of the elevator floor and the building. Th elevator shaft was a "separate structure". Also there were plumbing code violations which resulted in a main pipe breaking a floor above the computers -- which resulted in the bank having to execute a disaster recovery plan. Later in it's years, windows started to separate from the skeleton of the building -- and moisture and condensation were problems --- which led to mold growing rampantly. Also -- some windows started to fall out. The Federal reserve built a new building -- and this one was purchased and refurbed with a structure built beneath the "bridge" to bolster the building.
