\n The Fanling Bypass Eastern Section (FLBP) marks a major engineering milestone as the first project in Hong Kong to adopt the bridge rotation method, setting a new benchmark for innovation and safety in live railway construction. Serving as consultant, ArchTam provided multidisciplinary expertise to realize this complex and pioneering infrastructure. <\/p>\n<\/div>\n\n\n

Enhancing regional connectivity<\/h3>\n\n\n\n

The FLBP is a vital component of the Fanling North New Development Area (FLN NDA), designed to support a population of around 74,000 residents. As part of the Northern Metropolis \u2014 a strategic initiative led by the Hong Kong SAR Government \u2014 the bypass strengthens regional connectivity and alleviates increasing traffic demand in this rapidly developing area.<\/p>\n\n\n\n

A key challenge was constructing a vehicular bridge across an active railway line serving over 500,000 passengers daily, while contending with major underground utilities. Traditional segment erection methods would have required heavy lifting operations within limited night time windows, posing high operational risks.<\/p>\n\n\n\n

To overcome these constraints, the team implemented the innovative horizontal bridge rotation method. A 140 meter long bridge section, weighing more than 7,000\u202ftons (about 470\u202fdouble decker buses), was built adjacent to Fanling\u202fHighway and the East\u202fRail\u202fLine \u2014 an area further complicated by the presence of a water\u202fsupply\u202fpipeline and high voltage cables.<\/p>\n\n\n\n

The assembled bridge was then rotated horizontally into its final position overnight, enabling the structure to span the railway safely in a single operation. Advanced digital tools \u2014 including LiDAR systems, AI enabled\u202fCCTV and automated deformation monitoring \u2014 ensured precision and safety throughout construction and rotation.<\/p>\n\n\n\n

This method shortened the construction programme by approximately 12 months compared with conventional techniques, significantly reduced on-site risks, and minimized disruption to railway operations, enhancing safety for both workers and the public.<\/p>\n\n\n\n

Sustainable and collaborative delivery<\/h3>\n\n\n\n

Sustainability was central to project execution. Precast bridge deck segments were fabricated in Chinese Mainland and installed using launching girders and mobile cranes, reducing on-site concrete works and achieving an estimated 2,100-ton reduction in carbon emissions.<\/p>\n\n\n\n

As project consultant, ArchTam coordinated design, engineering and delivery across multiple disciplines, fostering seamless collaboration among teams from Hong\u202fKong, Chinese Mainland and Singapore. This cross-regional partnership enabled efficient delivery and meaningful knowledge exchange.<\/p>\n\n\n\n

Overall, the project delivered remarkable outcomes \u2014 reducing construction time, achieving around five percent cost savings, and setting a new standard for engineering innovation and excellence in Hong\u202fKong\u2019s infrastructure development.<\/p>\n\n\n\n
