Throughout the building they painstakingly preserved and restored as much of the original marble, woodwork and Art Deco attributes as possible. The escalators leading up to the grand, second story bank lobby were replaced with a marble and terrazzo staircase replicating the archetype design. Even the original, ornate entrance doors were reproduced to look as though you were stepping into the 1932 version of what was the tallest construction project west of the Mississippi River at the time.
All the old HVAC systems on newly renovated floors were replaced with new energy efficient VRV systems, which enable simultaneous cooling and heating, meeting the various needs for temperature control. Further efficiencies like repairing and resealing exterior window joints utilized long-life glazing and sealants, creating an air-tight seal around the entire building.
Electrical and plumbing systems have also been modernized to allow for improved safety measures and convenience. Advanced fire alarm and elevator upgrades along with other cutting-edge technological improvements enhance life safety measures in case of emergencies.
Modifications for ADA conformity, implementation of modern telephone, data and CATV cabling and additional computer infrastructure enhancements usher the building into the 21st century.
