Novel Japanese Approach To Renovate Canals


After an international call for ideas, Amsterdam has picked a novel approach from Japan to renovate its canal walls without the need for demolition and temporary works.

Methodologies proposed by Giken Ltd, based in Kochi, scored highest among 16 proposals, and the city and a Giken-led consortium have signed a partnership agreement.

Amsterdam owns and manages a network of 400-year-old bridges and quays, which are vulnerable due to their advanced age. In contrast to traditional construction methodologies, Giken’s method drives piles directly through the existing canal structure, and lets machinery “walk” along the installed pile wall, the company said in a press release today.

It added that its ‘Press-In’ technology is vibration- and noise-free.

Following further detailed design work, a pilot installation starts in 2021.
