Portland Japanese Garden Cultural Crossing Village

Location: Portland

Contractor: Performance Contracting

Architect: Kengo Kuma Hacker

Team: CWallA, L&W Supply, Scafco Steel Stud Company, USG Building Systems

The Portland Japanese Garden Cultural Crossing Village consists of three buildings made of steel, glass, exterior plaster, and green roofs. The architect was Kengo Kuma & Associates of Japan, known for designing the National Stadium for the 2020 Olympics in Tokyo. The local architectural partner overseeing construction was Hacker. The budget was $33.5 million with a 20-month construction schedule.

The first challenge was logistics of the jobsite. The garden lies on top of a steep hill with a one-lane dirt and gravel access road, restricting noise, light and work hours. The custom nature of all the finishes required complex framing for walls and attachment components for the bamboo ceilings.

In the Garden House, the ceiling was specified as whitewashed oriented-strand board, which was unavailable finished and had to be custom made.

But the biggest challenge was ordering and acquiring the FSC bamboo ceilings.

The bamboo ceilings were produced by a wood panel manufacturer, not a ceiling system manufacturer, and there were no installation instructions. The lead-time was so lengthy that Performance Contracting had to order panels from drawings, which meant starting over and reordering a few times. Swing shifts of tradespeople worked late into the night to get panels installed as they arrived on site.

The project was completed on schedule in April 2017 and was honored for its attention to detail, craftsmanship and complexity. The project has been recognized by the American Institute of Architects of Portland with an honor award, and Engineering News-Record named it Project of the Year for the Northwest region.

Juror's comment: “Committed to giving the most natural aesthetic, the contractor even aged the wood in the rain and sun to give it just the right look. The final result is impressive.”
