The historic South Station, a Boston landmark since 1899, is being reimagined with the $1.5 billion South Station Tower project—a 51-story skyscraper that will feature 700,000 square feet of office space and 166 residential units. This transformative development, recognized by CNN as one of the world’s top architecture projects for 2025, is setting new benchmarks for innovation and design.
CCL delivered advanced post-tensioning systems not only for the U-shaped concrete tunnel within the tower’s structural steel truss frame but also for the entire building structure.
The tunnel presented a unique challenge: it needed to be self-supporting during construction without additional shoring, despite its complex design and heavy reinforcement. Leveraging our unbonded monostrand system, CCL provided a solution that met these demanding requirements while maintaining structural efficiency.
By integrating our expertise in post-tensioning technology throughout the building, we’ve played a vital role in ensuring the structural integrity and sustainability of this extraordinary development.
South Station Tower stands as a testament to engineering ingenuity and architectural vision. A world-class project that redefines Boston’s skyline.
