KPF incorporated several setbacks into the design, and planned to construct the Travelstead Tower out of steel and reinforced concrete. The office floors were to be arranged in a cross, with columns in the building's core because of the presence of underground tracks for Grand Central Terminal. There would have been three sections in the tower: trading floors made of concrete; a series of office stories capped by a shoulder truss, and the top 20 stories above the truss.[10]
