LRT Seac Pai Van Line opens in Macau

Arup’s total engineering services played a pivotal role for this important spur line. Our multidisciplinary services covered rail alignment, architecture, station planning, building envelope and materials, civil, structural, geotechnical, bridge engineering, constructability, programme, MEP, fire, system assurance, transport consulting, environmental consulting, landscape and soundscape design, tree management, cost estimation, tender documentation and construction stage service.

Spanning a 1.6km elevated viaduct, the new line features two strategically located stations – Union Hospital Station and Seac Pai Van Station. Union Hospital Station also extends to the transfer station at Rotunda Flor de Lótus, enabling a seamless transfer to the existing Taipa Line. This expansion enhances the existing green transportation network, improving access to key destinations throughout the city. It not only facilitates easier commuting but also supports the city’s broader goals of reducing traffic congestion and pollution.

To further enhance connectivity, two footbridges with a total length of 300m link the new stations to Union Hospital and the SPV public housing development. Our design also considers potential future extensions of rail service to Coloane.

The innovative, human-centric station designs serve as the backbone that transforms LRT transportation system. The architectural concepts and design principles prioritise passenger comfort and wellness through environmentally sustainable architecture and effective way-finding strategies. Skylights at strategic locations provide natural light for safe movement, while natural ventilation systems optimise airflow, reducing energy consumption and carbon footprint. A static smoke discharge system ensures passenger safety during emergencies.

To expedite the SPV Line and minimise impacts on the Taipa Line implementation, the construction method and sequence were cautiously planned to ensure rail operation safety and compliance with the Taipa Line testing and commissioning programme. The elevated LRT viaduct, constructed using a balanced cantilever method with precast concrete segments, minimised traffic disruptions, demonstrating efficient construction practices.

Ho-kwan So, Associate Director and Project Manager at Arup, said, “The planning, design and construction of the Seac Pai Van Line span over a decade, showcasing our multidisciplinary collaboration of our teams across Hong Kong and Macau. Despite numerous challenges, we successfully delivered a project that significantly enhances connectivity and accessibility for the community. I’m grateful to everyone who played a part in making this project a reality.”

Simon Cheung, Associate Director and Architectural Team Leader at Arup, said, “This project reflects our commitment to creating spaces that prioritise passenger comfort and wellness while seamlessly integrating with the urban landscape. The innovative design not only elevates the aesthetic appeal of the stations but also fosters a sense of community by weaving in local culture and green elements. I believe this line will significantly contribute to a more sustainable and vibrant Macau.”
