Revolutionary High-Rise Building Technology

The Petronas Twin Towers in Kuala Lumpur has become the symbol of Malaysia's sustained economic development. In addition to its status as the tallest building in the world, the Petronas Twin Towers complex is also important as the embodiment of Hazama's world-leading high-rise construction technology. For example, this building employs a unique composite structure consisting of a tube structure of exterior columns and beams and a central core. This approach, which had never before been used in a high-rise building, has created flexible floor spaces without columns. The Grade 80 concrete (compressive strength 80Mpa) used in the project is the strongest grade in the world. Hazama also introduced an integrated project control system that included process management and the collation of design changes in a database. This approach was reflected in rapid progress, and the actual construction period for the entire project was just 29 months.

Large-Space Construction

The Tokyo International Exhibition Center Congress Tower dominates the skyline above Tokyo's waterfront urban sub-center. Hazama added a new page to the history of construction technology in Japan when it completed this massive facility. Uniquely shaped components weighing 6,500 tons were assembled on the site and hoisted to a height of 65 meters by four step-rod jacking systems using 64 step-rods. The result was a three-level structure with a massive interior space of 140,000 square meters. Assisted by advanced technology, including a high-precision computerized synchronization system and measurement control system, the four jacks precisely raised the massive structure into place in an unprecedented engineering operation. Hazama has further refined this jacking system to create a unique automatic building construction system, which is already in use.

Peripheral Technologies

In the construction of super-high-rise buildings and large-scale structures, Hazama uses a variety of technologies, including simulations to predict exterior wind patterns and environmental vibration and noise levels, as part of its efforts to create high-quality exterior environments. It also uses noise and air conditioning analysis and control know-how to design and create amenable interior spaces. A fire-prevention simulation system enables Hazama to design disaster prevention measures into its buildings.

Hazama can also propose appropriate maintenance and repair plans for existing structures. Its expertise in this field includes a comprehensive diagnostic system to assess how buildings have changed over the years and evaluate a variety of functional and performance factors, including facilities and the ability to withstand fires and earthquakes.
