To accommodate its needs, J.P. Morgan custom-designed its offices with advanced computer and communications equipment. The bank created trading floors at the base and removed one story from the original plans, slightly increasing all the other ceiling heights to compensate for the missing floor. Dining rooms were added so J.P. Morgan could give complimentary lunches to employees. The building's exterior shape and atrium were not modified, so no additional review from the city government was required. This sped up the project by about three years, since the various city agencies did not need to review the eligibility of any zoning bonuses being applied to the building. Steel contractor Frankel Steel and Steel Structures Corporation were jointly hired to fabricate the steel in mid-1986, and Steel Structures Erection Inc. was hired to erect the steel frame.
