Why It Has Stayed in Active Use for 60 Years
LONGEVITY
A building's value is sustained through daily maintenance and care. A structure that separates two wings and two cores, combined with 5,000 kVA of emergency power and a 24-hour disaster prevention center, has been kept in service through ongoing equipment upgrades. That record of stewardship has earned recognition including the first BELCA Award in the Long Life category.

Seismic design with separated wings and cores
Two cylindrical cores and office wings in an east-west SRC frame on a mat foundation, strengthened in 1996 with seismic upgrades and anti-shatter window film to ensure safety and peace of mind.
5,000 kVA emergency power and flood protection
Three on-site generators totaling 5,000 kVA, together with watertight doors at the subway connection and flood barriers at parking entrances, support a robust business continuity framework.
24-hour staffing at the disaster prevention center
Security personnel are on duty around the clock at the 1st-floor disaster prevention center, maintaining comprehensive security in coordination with surveillance cameras and the local police safety center.
Ongoing upgrades to shared facilities
Since the major 1996 renovation, the building has continued to update its equipment—elevators, HVAC, restrooms, and raised-floor systems—to meet evolving workplace needs.
