First National Bank Tower
First National Bank Tower
Engineering efficiency inside the tallest tower between Denver and Minneapolis.
Facility Description
The First National Bank Tower dominates the Omaha skyline, standing thirteen stories taller than the next tallest building in the city. At the time of its construction, it became the tallest building in a six-state region and remains the tallest tower between Denver, Colorado and Minneapolis, Minnesota.
The designers envisioned a landmark building that would embody both urban sophistication and Midwestern character. Rising 43 stories and encompassing approximately 999,100 square feet, the tower blends modern architecture with warm-colored masonry that reflects the region’s traditional aesthetic.
Five parking garages surround the tower and are connected through a network of private and public walkway tunnels, allowing pedestrians to move between buildings while protected from harsh Midwest weather.
Several unique features distinguish the tower:
- Architectural setbacks around the structure create the visual effect of a flower blooming as the building rises.
- The building has received four industry awards, including two from the American Council of Engineering Companies — the largest and oldest association of engineering firms.
- A striking 10,000-square-foot winter garden on the north side of the tower serves as a major architectural focal point.
Project Description
Originally constructed in 2002 with Ultra Z packages, the First National Bank Tower is now undergoing a large-scale retrofit led by Hydronic Energy. The modernization includes the installation of approximately 800 Griswold Controls Isolator Y valve packages.
Isolator Y valves provide a wide range of flow and PSID options and include pressure/temperature test valves, a drain valve, and a choice of union end pieces. Their compact design makes them ideal for installations where space is limited.
A key benefit of the Isolator Y package is the easily accessible flow control cartridge, which can be serviced or replaced without breaking piping connections. This allows system flow adjustments to be made quickly and efficiently as building requirements evolve.
