text: When 28 Liberty Street was completed, Chase occupied about  of space. Since most Chase employees worked in open plan offices, there were only 150 private offices for the 7,500 employees who worked in the tower upon its opening. The offices of Chase's three highest-ranking executives were on the 17th floor. These executive offices were connected to the lobby and the 60th story by an express elevator that stopped only on these three floors. The interior designers Davis Allen and Ward Bennett were responsible for the furnishings of Chase's offices, including much of the furniture and accessories. In addition, a board of curators selected the artwork for the building, and the firm of Chermayeff & Geismar & Haviv designed the graphics for the building. Bunshaft had planned to place a sculpture on the 60th-story landing but, after realizing that the ornamented spire of 40 Wall Street was visible from that level, he abandoned plans for the sculpture.
  Mechanical systems and elevators
  28 Liberty Street was largely built above a layer of quicksand located  below street level; the underlying bedrock was  below the quicksand. Workers solidified the quicksand by pumping  of sodium silicate and  of calcium chloride through more than 200 pipes. The excavations for the building's foundation reached  below ground level. Workers ultimately removed  from the site, which at the time was the largest single excavation project in New York City.
  Escalators connect the lobby to the concourse directly below it. The building was planned with 42 elevators and 12 escalators. As built, there are 43 elevators in total: three service elevators running from the basements to the lobby; six passenger elevators from the lobby to the basements; and thirty-four passenger elevators from the lobby to the upper floors. The upper-floor elevators ran nonstop from the lobby to serve the upper floors, and were arranged in five "banks": one elevator bank served the second through 17th floors; three banks each served ten stories between the 17th through 47th floors; and the fifth bank served the 47th through 60th floors.
