Rijk­swa­ter­staat man­ages and de­vel­ops the na­tional roads, wa­ter­ways and wa­ters of the Nether­lands. The colour yel­low has been chosen by the interior architect as it is a sig­nal colour in the world of traf­fic and en­gi­neer­ing. The yel­low rib­bon that runs through the floors, glass walls and ceil­ings con­nects the var­i­ous func­tions: re­cep­tion desk, train­ing ar­eas, break-out ar­eas, the li­brary and the cen­tral meet­ing area.
