BT Engineering designed the collision protection for the Zeeburg pumping station for the Amstel, Gooi and Vecht Water Authority. Here, excess water from Amsterdam's city center is pumped to the IJmeer via a siphon with three pipes under the Amsterdam-Rhine Canal.
The ascending pipe sections were unprotected against collision, which called for a robust safety structure. The limited space, the unknown condition of the existing siphon, and the continuous shipping traffic made this a complex design challenge. BT Engineering developed a well-founded and feasible design that guarantees the safety of this crucial water connection.




Results & benefits
From the early design stages, we considered the final implementation, including both practical feasibility and potential for changes, when making design decisions. This approach resulted in a well-developed, robust, and easily implementable design. When developing the design from preliminary to detailed design, only a small portion of the design components required modification. These changes were easily incorporated. The structure was even designed to be demountable, anticipating possible future modifications.
Impact
We delivered a feasible design early in the process that could be modified later during the asset's lifespan. After tendering, the design was finalized for implementation in consultation with the contractor. Less than 10% of the work required modification. 95% of the steel used can be dismantled into parts and reused. We guided the water authority through all five project phases, from variant study to implementation.

Why BT Engineering
BT Engineering has extensive experience in project execution through site engineering and on-site presence during implementation. We apply the knowledge and experience gained from fieldwork to create practical, feasible designs. We take responsibility for ensuring our designs can be successfully integrated into their environment, executed effectively, and gain acceptance. We also embrace the challenge of developing smart, sustainable, cost-effective solutions for complex situations.
