Overview

Taipei 101 features a 508-meter, 101-story tower with a unique profile, a five-story deep basement and a surrounding six-story retail structure. Thanks to tapering walls, most floor plan areas vary between 2000 and 2500 square meters (21,500 to 27,000 square feet), though they are as small as 47 square meters above the main roof. Building aspect ratio (height/width) to the main roof is about 9 based on its ‘waist’ (and 6.8 counting the wider base). The Taipei tower is equipped with the fastest elevators in the world, taking only 39 seconds to reach the observatory situated on the 89th floor: “Window of Future.”

The building is designed to open upwards, representing a blossoming flower that signifies financial richness, as well as everlasting vitality in the Chinese culture. Repeated references to the number 8 also reflect local culture. The architecture of the building relies upon the concept of inwardly slanted observatories. When used in conjunction with the high-tech, energy conserving, transparent glass materials and the innovative lighting design, the building is crystal-clear and elegant.

Our services were engaged by C.Y. Lee Architects to provide concept and preliminary designs, and to review the final structural design by the local engineer-of-record. We also responded to questions from the architect and advised the architect and owners during construction.

Tall & Supertall

For decades, our engineers have been pioneers in systems for tall and supertall buildings. From the development of the stressed-tube skin system in the 1980s to our unique design for Saudi Arabia’s Kingdom Tower – slated to be the world’s tallest building when it’s completed – we have explored new ways to improve upon tall building design and construction.

In recent years, towers have become taller and more visually exciting, creating new structural challenges. Our knowledge and experience, augmented by leading-edge analytical and design tools, are invaluable in providing designs that are safe, comfortable, economical, sustainable and constructable.

With a portfolio that includes three previous “world’s tallest” buildings and more than 100 other high-rises, Thornton Tomasetti has unparalleled experience in tall and supertall building design around the world.
