【Introduction of the project】
This project is a 255-meter-high office tower developed by Thailand’s leading corporate groups, the Saha group, designed to serve as a hub for group companies and tenants. Located along the Chao Phraya River in the Rama III district, the building features an iconic design inspired by the silhouette of the Bhumibol Bridge’s main tower, harmonizing with the surrounding area while establishing itself as a landmark.
As a RC structure, it boasts the greatest height ever achieved by Thai Obayashi and is also the tallest building within the entire Obayashi Group. The design concept embraces the “Spirit of Synergy,” aiming to create a sustainable, high-value building that has obtained international environmental certifications such as LEED and Fitwel 3-Star.
Not only improving building performance, the project demanded innovation in construction processes, requiring initiatives that prioritized environmental considerations and quality enhancements from the construction stages.
At the 39th floor, 151 meters above ground, the building incorporates a large-scale cantilevered Sky Lounge extending approximately 12 meters outward, with a width of about 45 meters and a maximum thickness of 4.5 meters. The lift-up method was adopted for its construction, improving quality, shortening the schedule, and enhancing safety. In addition, modularization of MEP works was actively pursued to reduce environmental impact, optimize labor, stabilize construction quality, and improve efficiency.
Through the proactive adoption of advanced technologies, the project delivered a high-quality, sustainable, and value-added building that met the client’s expectations, completed three months ahead of the contractual schedule, and achieved no accidents throughout the entire construction period.
