Acoustics are an integral part of

architecture that thoroughly affect how we

experience a space. Concert halls have a

unique obligation to cater the acoustical

qualities of their space to a multitude of

performances. Sonotune aims to solve the

problem of inconsistent acoustical requirements

in a beautiful manner where the flocking

movement of the system becomes a perfor-

mance in and of itself.

The kinetic wall system scatters and

absorbs sound waves by opening it's petals and

revealing a sound absorbent material. In order

to "tune" the acoustics, the array of kinetic

flowers can be programed to open a certain

percentage of flowers based on the acoustical

needs of each performance.

Sonotune is both a functional sound

module and a beautifully syncopated perfor-

mance, serving as a sign of commencement

before and after a show.

optimize the acoustical performance of a space."

The Catenary Cave serves as a place

for refuge and reflection in the heart of the HJ

Andrews experimental forest. The structure

caters to artists, scientists, and adventure

driven recreationalists. Located in the midst of

the Cascade mountains in central Oregon, the

building lies at 5,223 feet above sea level

overlooking eight major volcanoes. Summers

are hot and dry whereas winters often blanket

the site in 5+ feet of snow.

The structure is constructed of thin

steel plates and is entirely supported by its

own form. Using Antoni Gaudi's hanging chain

concept of structural design, Grasshopper and

Kangaroo were used to hang a hexagonal grid

under its own weight. When an arch or

surface is made this way, the form is in

complete tension. If the same form is trans-

lated to a rigid system and flipped over, the

structure acts in complete compression.

Structures made this way can span large

distances with a concrete shell only a few

inches thick. In this case, the structure is made

of thin steel plates.

This project involves an innovative

structural system to span the wide elevated

platforms. The roof structure is constructed

from consecutive bays of intersecting scissor

trusses which serve to support span and brace

the roof in all directions. To allow light and

natural ventilation into the space, the roof is

segmented to catch the prevailing winds.

The station also uses the "Spanish

solution" for more effective circulation as well

as increased boarding and disembarking

efficiency. The Spanish solution entails three

platforms. The two at the edges are for

boarding only while the one in the middle is

for exiting only.

Portland's International Raceway occupies land that has an enthralling past. Over time the site has been kneaded by it's contextual layers of anthropomorphic history and natural processes. When the racetrack was built, the nature of the site before PIR was lost. Historically, the land was a riparian area which was used intermittently by native Americans and by early American settlers for it's rich soils benefiting agriculture. As Portland grew, land was pushed around the peninsula to create habitable spaces. One of these places built on infill was the edge city of Vanport constructed mainly to house African American industrial workers in 1945. In 1948 Portland suffered a massive flood from the Columbia river which wreaked havoc on Vanport (Oregon's second largest town at the time). The water broke the levees and Vanport was completely destroyed. Portland's African American population was severely affected by the flood because of the segregated commu-nity; the damage was on par with that of Hurricane Katrina. Sadly, the story of Vanport is largely unknown as it brings up a dark time in Oregon's racial history. PIR's master plan acknowledges the history of Vanport and attempts to shed light on it's absent existence. It does this by constructing wetlands around the Racetrack that are structured by Vanport's major streets and blocks.

The remaining wetlands are raked to evoke the fluvial erosion that dominated the Columbia river flood plains before the land was altered for agricultural performance. The fluvial wetlands are constructed where the track curves are most extreme for the dualistic way that a racer moves through a track and how water moves through a river.
