Taoyuan City building exceeds flight height limit by 17 meters; city government says architect misinterpreted CAA notice

A commercial office building in Taoyuan City, Taiwan, has been found to exceed the legally permitted height by 17 meters, potentially requiring demolition. The building, known as 'Landmark Plaza Taoyuan B,' developed by Cathay Life Insurance, stands at 59 meters tall but is located in an area where the maximum allowable height is restricted to 42 meters.

The issue stems from a misunderstanding of regulations set by the Civil Aeronautics Administration (CAA). The architect involved in the project interpreted a CAA directive to mean that detailed documentation was only required for buildings exceeding 60 meters. Consequently, the building was designed to be 59 meters, just under the perceived threshold, and received its construction permit based on this interpretation.

“

This case is due to a difference in understanding of the CAA's official document. The architect, Mr. Wu, believed that according to regulations, documentation was only required for buildings exceeding 60 meters.

Taoyuan City's Department of Urban Development explained that the area around Taoyuan Airport is subject to strict height restrictions, similar to a Roman coliseum, with limitations becoming more severe closer to the airport. The 'Landmark Plaza Taoyuan B' exceeds its specific limit by 17 meters. Unless the CAA approves a remedial plan, the building may face demolition.

This situation is unusual, as previous construction projects within the CAA's controlled airspace in Taoyuan have consistently submitted measurement results, preventing such oversights. The city government is now awaiting a resolution, which may involve the CAA agreeing to a corrective measure for the building.

The circular cone surface of Taoyuan Airport is like an ancient Roman coliseum; the closer it is to the airport, the stricter the height restrictions.
