DfMA (Design for Manufacture and Assembly)

With year of experience with DfMA, Dragages has adopted DfMA successfully in our projects. The most recent example is the application of DfMA in the two Ventilation Buildings in the Tuen Mun-Chek Lap Kok Link project, in which precast slabs, beams, columns and staircases were used to save more construction time.

World’s Leader in Modular Construction

Modular Construction is revolutionising the construction sector over the world. Considered as a groundbreaker in modular construction, our sister company Dragages Singapore has completed several significant modular projects in Singapore, such as Changi Airport Crowne Plaza Hotel Extension in 2016, Woodlands Nursing Home in 2017, and world’s tallest modular tower Clement Canopy in 2019.

Advanced Tunnel Technology

Dragages can be named as a pioneer in tunneling projects in Hong Kong. We have deployed numerous in-house tunnel technology to combat the challenges in our technically-demanding projects.

1. Semi-automatic drilling robot ROBY850 – A smart robot which is capable to perform the work in full process, from setting out, drilling holes to installing anchors
2. Variable Density Tunnel Boring Machine (TBM) - Hong Kong’s first Variable Density TBM was deployed to cope with the unforeseeable ground condition when the TBM had to navigate through the reclaimed land.
3. Accessible Tunnel Boring Machine Cutterhead - This new technology in the industry will allow workers to access the cutterhead through a double-gate chamber without having to go through the time-consuming compressing process.

Intelligent Construction Method

With the determination to strive for excellence, the project teams of Dragages Hong Kong prides on innovation to execute our projects with highest efficiency and safety standard.

1. 15-cell Caterpillar Cofferdam – In the Tuen Mun-Chek Lap Kok Link Subsea Tunnel project, a 15-cell “Caterpillar”-shaped cofferdam was constructed to provide an unobstructed and safe construction space for the cut-and-cover tunnel
2. Peanut-shaped Shaft - In the MTR Shatin to Central Link – Causeway Bay Typhoon Shelther to Admiralty Tunnels – Contracts 1128 project, a strut-free “Peanut” shape shaft aiming to enhance the working environment inside the shaft and ensure a safe construction method.
3. 180-degree U-turn Operation of Tunnel Boring Machine - Hong Kong’s first TBM U-turn operation happened in the Lung Shan Tunnel project. When the gigantic excavation machine finished excavating the first tunnel, it was turned 180 degree so it could start excavating another tunnel in the opposite direction right away.
