Winter 2013 Course - Arch 585 Terminal Design Studio Duration – In Process Professor Kevin Nute The US Government built a series of missile silos at the height of the Cold War. A complex was constructed in Chico, CA and was in operation for 3 years, before it was stripped and abandoned. The complex has sat empty for many years. The project is to construct a new Cold War museum that begins to reveal the structure and complex that has been hidden and forgotten for so many years. The existing complex is completely underground, hidden from view except for the tops of the missile silos and entry portal. I begin with a direct connection. A single ramp that descends into the ground and reaches the -60’ level that the personal tunnels are at. The ramp is 1 to 20 with a series of landings and connects the antenna silos with one set of missile silos at the opposite end. The ramp becomes the gallery and parts of the complex begin to be revealed as you descend into the ground. There are two galleries. The main gallery is along the ramp and a secondary return gallery is at a higher level looking down onto the lower ramp gallery.

Fall 2012 Course - Arch 584 Design Studio Duration – 4 weeks Professor Mark Donofrio Autzen Bridge connects the campus of the University of Oregon with Autzen Stadium. It crosses over the Willamette River. It is heavily trafficked by both pedestrians and bicyclists. The bridge currently has five areas where the bridge deck extends out three feet and allows space for a bench. These benches are heavily used throughout the year. These are located on only one side, and are very small and don’t allow people to fully step away from the traffic on the bridge. The bridge provides a space for people to stop and becomes in itself a destination, but lacked adequate space and shelter to successfully provide that. The benches sit within the path of the bridge, there is no shelter or covering to protect form the elements, and the bridge doesn’t take advantage of the views it has on both sides.

New Plan
Bridges tend to be a way to travel from point A to point B. This new addition attempts to pull people away from the traffic and the bridge by creating viewing platforms on both sides, thus making the bridge a destination. People can step aside and pause on their journey over the bridge. These viewing platforms provide seating and separation from the movement on the bridge and provide shelter from the elements. 12

Fall 2012 Course - Arch 584 Passive Heating and Cooling Duration – 10 weeks Professor John Reynolds The project is live / work housing and so there is the ability to look at both living and working situations and how those can be affected by passive heating and cooling. A steep slope slopes up to the north. It will provide challenges since they are stacked and the units are long and narrow. The majority of glazing is on the North and South sides, which is the narrowest point of the units. The living spaces are about 1500 sf while the workspace is 1000 sf. The work space is located on the first floor, with living on the second and bedrooms on the third floor. The projects were designed to have operable sliding shades on the exterior to allow residents the opportunity to control their own comfort. Most of the units share a common wall which increases its thermal insulation and mass. Two cool towers were used to cool the work space. With the benefit of the height, two were used to account for the cooling load of the work space. The work space is also cooled using night ventilation. The roof is used to cool the living space. A ceiling fan will circulate the air in the space.

Each unit has a two story living space on the South side. Operable shading was incorporated to provide residents with more customizable options with shading. It also provides greater opportunity throughout the year to improve thermal comfort. The overhangs and fixed louvers shade the hot summer sun, while allowing the sun to penetrate in the winter.

The roof pond can only be used for the living space. The work space is under the living space and therefore doesn’t have a roof to put the roof pond on. The roof is flat to accomodate the roof pond. The cooling needs of the living area could have been satisfied by a roof pond, but because of the clear story windows and cool tower on the roof, a secondary source of cooling was accomplished through stack ventilation and night flushing.

andshell BBandshell
Pullman, WA
Spring 2006 Course - Arch 303 3rd Year Studio Duration â&#x20AC;&#x201C; 13 weeks Professor Michael Owen Sunnyside Park is located in the small college town of Pullman, Washington. The Pullman City Council would like to build a bandshell to be used for different community events throughout the year. The bandshell would utilized with and without a speaker system. The complex would need to include the bandshell, restrooms, concessions, and changing rooms. My initial inspiration came from the phonograph. I was inspired by the interesting angles, its ability to amplify and project sound. The angles of the phonographâ&#x20AC;&#x2122;s horn are very much a practical aspect and create an interesting focal point. I knew that I could use similar angles in creating my bandshell and accessory spaces. The horn is such a central part of the phonograph and I wanted my bandshell to have the same importance and focus. Working in plan, I wanted to create a layout that allowed the bandshell to remain the focus, but that was able to hide the accessory buildings. This allows visitors to view a performance without the distraction of the concessions or restrooms. The changing rooms, concessions, and restrooms are hidden behind the bandshell, and connected by a central hallway located between both buildings, allowing access from the changing rooms to the stage.

Fall 2011 Course - Arch 571 Building Enclosures Duration – 4 weeks Professor Don Corner The primary focus of this course was focused on the weather envelope that surrounds the primary structure in a building. The requirements for this detailing project, was to design and detail an operable shade and wall assembly. The projects provided experience in construction detailing and technical drawing and specifications. The design is for a new building with a glass façade. The facade must be operable, providing a higher level of comfort to the occupants. The glass façade features a venting panel used for night venting, and operable windows for occupants during the day. The operable shade is pulled away from the building to allow for the windows to open, but to increase airflow when the shades are closed, allowing air to continue to circulate behind. The operable shades are broken up into panels allowing for each section to be opened separately. While allowing for a more customized experience in the interior, it creates a living façade that begins to change as the occupants and the days change. The façade reflects those inside and changes day to day, hour to hour, and occupant to occupant.

Spring 2010 Yakima Valley Farm Workers Clinic Design - 8 months Construction â&#x20AC;&#x201C; 3.5 months YVFWC was awarded a CIP grant to complete a remodel in its Mountainview Womanâ&#x20AC;&#x2122;s Clinic. The clinic is a 33,000 square foot clinic that provides services to low income women and children. The scope of the project included remodeling and updating the clinic with new finishes, and some minor construction, both inside and outside. The project was federally funded and therefore needed to follow the Davis-Bacon wage scales. I worked alongside another project manager and we worked with a project team, including I.S. department, procurement, facilities, and clinic operations staff on the project. I was responsible for developing and finalizing the design and construction documents. Working with the project team, I developed the layout and construction documents and worked with an interior designer for material selection. I worked with the project team to develop the color palate for the exterior of the building as well as the colors for the new sign. Colors were chosen based on the requirements of the city. The clinic remained open while work was coordinated around working hours. The remodel included new carpet, paint, and minor remodel and construction in some spaces. The Project earned a Grandview Beautification Award for its design and contribution to improving the downtown area.
