Project
Lijnbaan
On the Lijnbaan in The Hague, the first pilot quay renewal was carried out: 43 meters of quay wall replaced vibration-free while preserving trees, an important practical test in the early phase of what would later become G-kracht .
Challenge
During the research and development phase, Gebr. De Koning and Van Gelder had the opportunity to carry out a pilot project along Lijnbaan in The Hague. The location, a narrow urban zone with limited workspace, provided an opportunity to test an innovative approach.
The 43-meter quay needed to be replaced while retaining four mature trees along the waterfront. The objective: to demonstrate that quay replacement is possible without demolition, construction excavation or severe nuisance - a compact, quiet, tree-friendly alternative.
Implementation
As the first practical application of the method, the Gyro-Press system was used: tubular steel piles were installed vibration-free through the existing structure. Precast concrete elements formed the new quay wall, and the trees were left untouched.
The compact approach minimized the impact on the environment. This project proved that innovative quay renovation is possible in places with minimal space, laying a foundation for later, larger applications.
Result
The successful completion of this pilot gave the confidence to scale up the method. The lessons from The Hague formed the basis for subsequent cooperation with the City of Amsterdam and the creation of G-kracht.
The pilot proved: vibration-free, quiet and sustainable work is also possible in a busy city - with respect for trees and the environment.
