[AC-CA] ist ein inter­na­tio­na­ler Architekturwettbewerb-Veranstalter, der sich auf pro­gres­sive Wett­be­werbe mit einer Reihe von Geld­prei­sen und der Ver­öf­fent­li­chung der Gewin­ner kon­zen­triert. Den Wett­be­werb habe ich hier vor­ge­stellt. Ein Arti­kel über Platz 3 und Platz 2 gibt es auch.

1. Preis: Pede­strian bridge

Con­cept: The pro­ject pro­po­ses a cen­tral enclo­sed space, a water plaza. A space that is defined by its shape, where boats cross through and pede­stri­ans and cyclists stroll along its peri­me­ter. The act of framing a part of the river, brings a new value to it.

Struc­ture: The bridge has a sim­ple, round shape and is for­med by the most clas­sic of struc­tu­ral types: the steel lat­tice shell. This inten­si­fies the purity of the ori­gi­nal idea and justi­fies the ratio­na­lity of the cho­sen solution.

Expe­ri­ence: Cros­sing can be per­for­med both above and below the water level. This dua­lity of paths brings in a new way to cross the river. The acom­pany­ing pro­gramme is incor­po­ra­ted inside the encir­cling cil­in­der, ori­en­ted inwards, and opening towards the new urban space.

Acces­si­bi­lity is gran­ted both for bicy­cles and the disa­bled, with a gent­ler slope along the above-water span of the bridge. Boat tran­sit under­ne­ath com­plies with height and depth regulations.

Sus­tain­ab­lity: Given the sim­p­li­city of its con­struc­tion sys­tem, the bridge can be built from dis­car­ded or reco­vered shi­py­ard steel from the local naval indus­try. Wood, which has a low environ­men­tal impact while pro­vi­ding the necessary resis­tance for such a humid loca­tion, is used in the interiors.
