该项目是波特兰环保局的一部分，共11640平方英尺（约1081㎡），包括办公场所、接待区和公共会议室。这里不仅容纳污水处理工程部门，而且具有虚拟教育体验的功能，整栋建筑与可持续景观融为一体。

The Columbia Building supports the City of Portland’s Bureau of Environmental Services. Housing workspace, a visitor reception area, and public meeting spaces, the 11,640-square-foot building not only supports the engineering department of the wastewater treatment facility but also functions as an immersive educational experience, all integrated within a sustainable landscape.

这座新建单层建筑具有七个折叠式的现浇混凝土屋顶，种植屋顶引导雨水沿着坡道向采集系统汇聚，最终流入哥伦比亚河。

The new single-story building features seven folded cast-in-place concrete roof forms that channel stormwater through a planted roof, which drains along the berms into a visible collection system that leads to the Columbia River.
