The pier of the bridge rises 200m above the water surface of the river and required detailed planning in compliance with strict safety guidelines.

Peri is assisting with the project by providing individually planned and coordinated formwork and engineering solutions to ensure that the unusual pier design can be constructed on schedule.

The structure is designed by Zaha Hadid which won the Danjiang Bridge International Competition back in 2015 for the design of the asymmetrical bridge. Once completed, the bridge will connect Tamsui District in New Taipei City with the Bali District across the river – thus relieving the pressure on other transport routes.

The pylon in the centre of the bridge towers into the air in the shape of an upturned “Y” and stands, figuratively speaking, with its two legs in the river. The stay cables, which run in parallel to the top of the pylon from both sides, give the structure a futuristic appearance.

Peri was involved in the construction of the pylon by providing, among other things, a custom-designed formwork solution for concreting a total area of 18,000m².

To create this futuristic look, Peri developed a freeform formwork system specifically for the project to construct 3,000m² of the entire surface. The complex, ever-changing shape of the pylon, which stretches upwards over 53 sections, posed the biggest challenge. Peri provided versatile VARIO, SCS and ACS, which could be individually adapted to the varying geometry.

“Since we have been using Peri products, the project has been running smoothly. The efficiency is constantly high so that our requirements regarding the progress of the projects are fully fulfilled.

For us, it is a good feeling to know that PERI is always able to competently solve any problems that arise during the entire construction process.” said Zeng Wei-Cheng, Site Manager, KSECO. 

The project is scheduled to be completed in 2025.
