Project Story
A New High-Rise Urban Center

Created in 2017, Sasashima Live 24 is a new international gateway. The large 22.1 hectare site is 1km south of Nagoya station, and was once a freight depot.

Takenaka designed and constructed its core facility, “GLOBAL GATE”, supporting the client and the project from the concept stage to opening.

An Open Gate to the World

In 2007, 10 years before the opening of the building, the city of Nagoya held a competition, inviting development concepts for a new urban complex that would foster global cooperation and exchange. Takenaka won the project competition, partnering with Toyota Tsusho Corporation, Daiwa House Industry, Nippon
Tochi-Tatemono, ORIX Corporation and Meitetsu Real Estate Development. Its concept of an eco-friendly “Global Gate” was a finely balanced proposal for a commercial facility including offices, a hotel and a conference center, with an international outlook. It immediately attracted a lot of interest.

The client commissioned us to do project management and we handled everything from hardware to software, increases in floor-area ratios thanks to special area urban regeneration, environmental assessment in consultation with the government, facility program planning, tenant leasing, and applications for subsidies for CO2 conservation.

Broadband Safety and Security

Takenaka uses original technologies to strengthen disaster protection and also save energy.

We prioritized disaster protection. The site is situated next to a canal on soft ground, which increases the possibility of liquefaction in the event of the large earthquakes predicted to occur in the near future—in the Tokai, Tonankai and Nankai regions. To make the building even safer and more secure, ground reinforcement was done with the TOFT ground improvement method, which has been shown to be effective in preventing earthquake damage in the past. In addition, Takenaka used its Soil Clavette method, to achieve an even higher level of safety and security.

Broadband Damping is employed using high-strength concrete CFT columns that control vibration from the subtle vibrations caused by wind to larger seismic vibrations. Emergency generators are in place to maintain power.

PC Pilaster—Realizing Design and Energy Saving Technology

For energy saving, we have adopted “PC Pilaster”, which is a precast concrete column on the exterior wall. The column protrudes from the glass façade, so while it ensures the view, it also shields the inside against direct sun light. The inside of the column has an air passage that allows air from the outside to be channeled inside periodically. In addition, it channels hot air from air conditioning units in summer and cold air near the window in winter, adjusting air temperature to an appropriate level before the returning it inside.

This measure and others won the building “S”—the highest grade in the “Comprehensive Assessment System for Environment CASBEE Nagoya”, which assesses and grades buildings for environmental performance.

People in Charge

Katsumi Akagi,
Marketing Department, Nagoya Branch

I have been part of this project for 10 years, right from the project competition to the opening. The project was stalled for 4 years because of the financial crisis of 2008 and the 2011 Great East Japan earthquake. But even then, we shared the passion of our customers to realize this project no matter what and continued to negotiate with administrative agencies to respond to the demands of our customers. I believe the biggest factor in the success of this project was cooperation with our customer which went on for a long time—over 10 years.

Yoshihisa Kominami
Project Development Department

I was in charge of the plan proposal and creating the consortium in the project competition phase.
After winning the competition, we were commissioned to do project management. I have supported the project going forward while building consensus with the client from the planning of the facility program to the negotiations with the administrative agencies for urban planning and assessments.

For the commercial facility, we wanted to differentiate it from others in the city center and suburbs, and create added value specific to this site, so I was in charge, right from the concept stage to the start of tenant leasing, also handling plans for rooftop farms and the like.

I realized through this project, the importance of not only providing hardware for a building, but also providing software solutions looking beyond completion.

Design Department, Nagoya Branch

This building was designed as a core facility with various functions, including energy conservation in an area that features over 25% cultivated greenery.
The commercial facilities are located between green areas such as rooftop gardens and farms, making them more amenable to local people.

From the hotel on the higher floors you can enjoy a good view from downtown Nagoya all the way to Gifu and Mie. The 6 story lighting of the high lobby, including brightness and color changes according to the brightness outside, so you feel relaxed at night and refreshed on departure in the morning. I saw all kinds of people using the facility after it was completed. I was pleased that we had exceeded the limits of conventional construction.

Technology Department, Nagoya Branch.

We had to complete a large project with a total floor area of 157,000㎡ and 3 towers in just 30 months. This was a very tight schedule and our client’s most important requirement. We started front loading 1 year before construction, conducted planning with our associate companies, and held technology meetings at our headquarters, taking advantage of the knowhow of the whole group. These measures yielded a 20% improvement in productivity.

In addition, we have created full-size mockups of PC Pilasters, 4,500 of which are used for the exterior of the building. We also conducted typhoon tests, to verify in advance the wind pressure resistance and cut-off performance.

For construction, the clearance between the adjacent curtain wall had a big effect on cut-off performance, so it required high precision and extreme care. We completed almost all of the building 1 month early, earning the trust of our client.
