Rising 210 meters above the city skyline, Hangzhou TCC sets a new benchmark for mixed-use developments that blend design ambition with functional performance. This landmark project brings together office, hotel, and commercial spaces within a striking architectural form that demands equally advanced facade access solutions.
Delivered by CoxGomyl, part of the Alimak Group, the system reflects a strong focus on engineering excellence and long-term asset value. From the outset, the challenge was clear. The building’s complex geometry, combined with a large photovoltaic canopy and curved facade transitions, required a system that could deliver full access without disrupting the structure’s visual appeal.
The solution needed to support safe and efficient maintenance while remaining discreet when not in use. CoxGomyl engineered a BMU system that delivers complete facade coverage while preserving the architectural intent of Hangzhou TCC.
Hangzhou TCC is a mixed-use development that combines office, hotel, and commercial spaces within a 210-meter structure. The project required a high-performance facade access system that could adapt to complex architectural elements while maintaining a clean rooftop appearance.
A defining feature of the building is the large photovoltaic canopy installed above the western and southern podium areas. The facade transitions into a curved arc as it meets the canopy, creating a challenging geometry for maintenance access. The client required a solution that ensures complete facade coverage while keeping equipment concealed when not in use.
To address the building’s unique design, our team engineered a tailored BMU system that delivers safe and efficient access across all facade areas. A fall arrest lifeline system was installed across the photovoltaic canopy and curved transition zones, enabling secure maintenance operations while ensuring every section of the facade remains reachable.
The system achieves 100% coverage by integrating access solutions across both vertical and curved surfaces. This approach supports long-term maintenance needs and enhances operational safety. It also aligns with modern building requirements where renewable energy features must remain accessible without compromising performance.
The project also required the facade access equipment to remain hidden from view. To meet this requirement, a single-stage telescoping mast was installed. When fully elevated, the mast reaches 15 meters, allowing the BMU to remain completely concealed when parked.
This design preserves the visual integrity of the building while providing the reach and flexibility needed for efficient facade maintenance. The result is a solution that balances aesthetics with functionality.
Installation required precise planning due to a compressed schedule and restricted site conditions. Construction was paused during the Hangzhou Asian Games, reducing the available working window. At the same time, installation overlapped with tower crane dismantling, limiting lifting operations and requiring close coordination across teams. These factors created a complex environment where timing and sequencing were critical to project success.
Facade Access Solutions China implemented a structured installation approach focused on safety and efficiency. High scaffolding systems supported the assembly of the mast and telescoping boom in controlled stages. Close coordination with the main contractor ensured smooth execution within the limited timeframe.
Despite the challenges, the BMU system was delivered on schedule. The project highlights CoxGomyl’s ability to manage complex projects and reinforces the value of reliable facade access solutions for long-term building performance.
