During the feasibility study, our engineers have proven that the scheme is technically feasible. The church sculpture can be built and can be made strong, stiff and durable.

STRUCTURE

The sculpture is composed of 41 piles with heights between 12 meters (nave) and 25 meters (tower) above mean sea level. They are fixed on land onto a steel beam grid to ensure exact tube positions and verticality.

FOUNDATION

The foundation is made of a concrete slab and sheet pile walls around it for scour protection. The steel beam grid with the visible tubes on it is encased in the concrete slab. Also rocks are encased at the edge of the slab to protect against abrasion.

PILES

The piles consist of a concrete core and stainless steel cladding tubes. The concrete acts as the load bearing part of the pile whereas the stainless steel protects against corrosion and provides a perfect reflecting and mirroring surface.

WIND

The tubes are themselves strong enough to resist wind and wave forces. They are stiff enough not to be susceptible to cross wind excitation.

BUILDING THE SCULPTURE (STEP BY STEP)

1. The piles are assembled and fixed onto a steel beam grid in a dry dock.

2. At the site a cofferdam is built with sheet pile walls.

3. Remaining animals are taken out and a part of the seabed is dredged.

4. Wooden piles are driven into the seabed and levelled. They act as temporary support for the sculpture before the

concrete is placed.

5. The sculpture is floated out to the site on a pontoon.

6. Jack-up barges will lift the sculpture and place it onto the wooden piles inside the cofferdam.

7. Heavy rocks are placed around the sculpture. They will protect the concrete slab against abrasion.

8. Concrete is placed inside the cofferdam onto the steel beam grid.

9. The overhanging sheet pile walls are cut. READY!
