G-Kracht B.V., a joint venture company consisting of Dutch construction companies Gebr. De Koning B.V. and Van Gelder B.V., and Giken Europe B.V. (hereafter “GIKEN Europe”), a group company of GIKEN LTD. (Head Office: Kochi-shi, Kochi; President: Atsushi Ohira; hereafter “GIKEN”), signed a framework agreement*1 with the City of Amsterdam for the commercial phase of a project to develop new technologies for quay wall renovation for the World Heritage-listed Canal Ring Area of Amsterdam on April 10. The pilot work completed last March (demonstration construction extending 208 metres)*2 has been positively received, and contract orders for 1.3 km of construction (including the pilot work) over the next four years will be secured. Press-in construction is scheduled to commence this autumn.
During the pilot work, efficient press-in operations were achieved under constraints identical to the actual construction environment. Technologies employed included the Gyropress MethodTM for tubular pile rotary cutting press-in through existing revetments without removal, and the electric "GRB SystemTM," which operates machinery on existing driven piles, eliminating the need for temporary work. The construction was carried out under the gorgeous scenery of the World Heritage site provided by rows of trees, and no trees were cut down. In addition, work was vibration-free, noise-free, and contributed to carbon neutrality. Local residents expressed their amazement, and the project owner was very impressed with the operation. In the commercial phase, with the eyes of the world on this project, the superiority of the press-in technology will be demonstrated across various regions, accelerating the adoption of this construction method and contributing to the resolution of global construction challenges.
*1 A mechanism in which the project owner selects long-term nominees (framework companies), agrees on contract conditions for individual orders within a specified period with these companies, and determines the contractor based on this agreement.

City of Amsterdam and G-Kracht B.V. sign framework agreement
■Commercial Phase Schedule
During this phase, renovation work covering a total of 3.3 km (including pilot work) over eight years is planned, and the group responsible for development will be awarded the contract for the work using the innovative technology developed for the project. G-Kracht B.V., having demonstrated the superiority of the press-in technology and successfully completed the pilot work, has secured contract orders for a total of 1.3 km (including pilot work) over four years. Following this, contracts will be renewed every two years based on construction performance, with an additional 2 km section expected in the next four years.

After pilot work
■Project Schedule
The Gyropress MethodTM and GRB SystemTM are expected to be adopted as one of the standard construction methods for this project after the commercial phase. Due to their overwhelming superiority compared to other construction methods, we anticipate an increase in their usage by other companies. This expansion in the use of our technology by other companies and their sites is expected to accelerate the adoption of the construction methods, along with increased sales and rentals of our press-in machines and system equipment. With renovations totaling over 200 km planned, we expect sustained revenue generation.
