the following two projects for The Hague and Zaanstad did not survive long

arch which would have connected two perpendicular traffic islands with two half arches connecting above the center of the intersection. But the communication between the committee for the arts and the department of public works failed - as the plans for the intersection were revised before the committee was informed - and the sculpture was ready. it waited almost twenty years before it would be installed in Rhoon Holland.
Wave was installed in the a new housing area for the lower classes in the Stuwstraat. After its first year the inhabitants had cut the connections with grinders and pulled on the elements with their cars. So it was dismounted and stored until the pipes could be reused. Five years later the curved pipes were applied to construct c.y.f. in Houten Holland.
victory - was installed in Zaanstad - Holland in 1987. But the populist mayor Vreeman gave in to an almost fifteen year protest by a certain Mr. Schot and had it removed. Here it is stored in the Zaanstad industrial area, across from Amsterdam. I didn't know where exactly is was stored, but found it via the satellite image of this area.
