[1] The building is made up of over 9,135 tons of steel, supported by 28 caissons, going 80 feet (24 m) down into the Earth, and over 36,000 cubic yards (28,000 m3) of concrete.

A 294-seat auditorium is located in the tower complex with an executive parking garage immediately below it, and the building itself is connected to the CitiWalk system.

Underground, there is a mini-mall, SeaGate Shops at CitiWalk, that was left primarily vacant after the departure of O-I.

When the building opened, Edwin Dodd, then O-I's Chairman and CEO, exerted his considerable influence to fill the Promenade level shops with tenants.

The mini-mall has a small eatery area that leads to Promenade Park and Fountain Square, which features the Dimitri Hadzi sculpture, Propylaea.

At that time the headquarters were moved to the Levis Commons complex in the nearby suburb of Perrysburg, Ohio, where the company already owned a large facility.

The company chose not to occupy the top floors, including the prestigious offices of the O-I executives, because renovation would cost too much.
