225 West Wacker Drive is located at the southeast corner of Wacker Drive and Franklin Street. The 34,310 SF site consists of a full city block bordered by Post Place, Lake Street, Franklin Street and Wacker Drive. It has 107 feet of frontage on Wacker Drive and 320 feet along Franklin Street. The 31-story building contains 650,812 rentable square feet of office and retail space, and a parking garage for 229 cars. A typical office floor contains between 25,037 and 25,537 square feet of rentable area. The building has a full basement consisting of mechanical and electrical service facilities and a loading dock with six truck berths. The service elevator serves all floors in the building, basement through level 31. Access to the parking garage is available from both Post Place and Franklin Street. The enclosed parking garage has seven levels and is served by a separate shuttle elevator to the Ground Floor. Pedestrian access to the building is from Upper Wacker Drive through an exterior arcade into the Wacker Drive Lobby. From Franklin Street, one enters into the vaulted Franklin Street Lobby which provides access to two elevator lobbies, each containing six-high speed, fully automated elevators serving the low-rise and high-rise office suites. The building structure is made of Class I-A, fire resistant, reinforced concrete columns and floor slabs designed to provide for superimposed distributed loads averaging 70 pounds per square foot. Interior areas north and south of the core have been designed to accommodate 125 pounds per square foot for such uses as computer and file rooms. The foundation system consists of concrete belled caissons extending approximately seventy feet below ground level to suitable bearing on hard pan clay. The granite, marble, aluminum and insulating glass exterior wall maximizes tenant views and light while maintaining the highest practical energy conserving qualities. Air conditioning is provided by a variable air-volume system with supplemental perimeter electric heat through fan-powered, variable-air-volume units located above the ceiling. The building is protected with an automatic fire protection system. Fire command, sprinkler, smoke evacuation, alarm and exiting systems are in conformance with the life safety provisions of the Chicago Building Code. The building also has a computer-controlled energy management system. The life safety communication system has a one-way emergency paging system on all floors and a two way firemen's telephone system in all elevators and at every fifth floor in exit stairways. The life safety system status reporting, controls and master communication components are located in the fire command center behind the security desk in the Franklin lobby. An electronic key fob must be used to gain access to the Building 24 hours per day, 7 days per week. The key fob must also be used from 6:00 P.M. through 8:00 A.M. Monday through Friday and 24 hours on Saturday and Sunday to access the passenger elevators, which compliments the security officer that is on site 24 hours a day.
