On 14 June 1918, the Zuiderzee Act came into force and made possible the construction of the Flevopolder. On the occasion of the 100th anniversary of the Zuiderzee Act, Bob Gramsma created the monument Riff, PD#18245.

On three pile foundations and a complex construction such as used in bridge and boat construction, Gramsma poured some 15000 cubic meters of agricultural and Zuiderzee soil. In this heap, he made a large opening, which was then covered with a layer of shotcrete. Gramsma then removed all the soil to ground level, leaving this concrete cast, mixed with remnants of the Zuiderzee sea floor.

Riff, PD#18245 is a cast of the mark made by Gramsma in the Flevo polder soil; as such, it reflects the reclamation and artificiality of the polder. Gramsma's newly formed landscape, which rests on piles like a building, provides shelter to animals and mosses. Visitors can use the stairs and let their gaze wander from above over the old country at Elburg and the new man-made landscape with its dikes, roads and ditches.

Construction of Riff, PD #18245

Riff, PD#18245, the eighth landscape artwork in Flevoland, is built up in several stages, each of which is important to both the creation and the meaning of the artwork.

The composition and firmness of the soil on site affect the construction and appearance of the exterior. The excavation process leaves its mark. Wind, water, temperature and other weather conditions play a role as well. All these influences and processes will not come to a sudden standstill as soon as the concrete object has emerged.

In several different stages, visitors will be able to witness the building process of the complex construction consisting of rafters, ribs and braces such as those used in bridge and boat construction, before they are finally hidden from view once the artwork is finished.

In September 2018, under great public interest, the first pile of the artwork was driven into the ground: the first stage. The static construction was presented on 14 November 2018, coinciding with a symposium on the centenary of the Zuiderzee Act. The public opening was on 12 October 2019.

This, then, will function as an open end, since subsequent stages will see the construction of the natural area that surrounds the artwork, the first vegetation in the form of mosses, and possibly the first inhabitants of Riff: a pair of breeding birds or solitary bats.
