As we arrive at the last few sentences of the final thesis conversation, it becomes evident that the project holds some ground. The foothold that it finds, is a way of working that relies on exploration, discovery, challenges, failures and the architect to develop an informative design process. Drawings, models, and full scale prototypes become a synthetic medium in which the architect is able to discover new opportunity from real world experiences. Often in academia we find that speculation and observation generate designs both past and present, formulated along side the ambitions of case studies or nearby peers. This methodology hopes to bring new light and fresh air to students and possibly practitioners. It singles out the architect, enabling them to becomes inhabitants of the spaces they create, in order to inform the design decisions they will continue to make.
The film demonstrates the design approach and methodology I have constructed for my thesis. A methodology where testing and inhabitation begin to inform design decisions, in turn making architects more aware of the spaces they create.
Each drawing is constructed to show weather patterns, site constraints and the successes and failures of the design, highlighting informative re-design changes for the next iteration. The entire journey demonstrates my thesis and interest in forming a methodology where architects and designers create intimate relationships with the spaces they create, as a way to elevate our awareness as curators of the built environment.
MC_01 is our first camp on the mountain. It has become apparent that energy for powering stoves and electronics (gps phone, camera, etc) that we are using for three weeks needs to be budgeted. A solar system that works with the geometry of the tent, or a tent which generates geometry from the dimensions of a solar panel would be beneficial.
As we reach basecamp we notice that wind speeds are gusting at over 40 mph, this will be a major challenge. The testing I had done was to design a tent with an orientation into the wind, responding to winds that we would have in urban spaces. In extreme climates, because the systems are so large and spaces are so open, winds are unpredictable and come from all directions. They howl across the valley, along the side of the mountain and through the main traverses. A responsive structure that utilizes rotary sensors and arduinos could shift with the movement of the winds.
In academia, we rely on presentation models and drawings as a critical medium to our conversations. I want to add a chapter. I want to display models that have been shredded by wind, and bleached from sunlight. Physical models we can learn from. Now, back in Ann Arbor I am able to examine my torn, patched, and sun burnt full scale model. Through my proposed working methodology it becomes evident the successes and failures of the design intentions. As I begin the process of informative re-design, I gather the rich body of knowledge from my research to test, alter and modify the tent through a series of drawings.
As I return from the main research and testing phase of the project, I am able to continue the design and conversation back in Ann Arbor. The work has unexpectedly granted me the opportunity to engage with a multitude of people interested in the expedition. For me, it is a fantastic way to frame my thesis outside of the college and into the world.

Extreme climates and architecture. For me this project granted an opportunity to roll up my sleeves and test a design that was generated digitally and then fabricated using CNC milling machines in combination with hand construction. Throughout the process I have been able to be the designer, occupant, explorer, and researcher. Perhaps this is a working methodology that architects can utilize to formulate relationships with the spaces we create.
People sometimes ask the question, why? Its well below zero, the winds are relentless, the food and water are barely tolerable, what is the point of going to these extreme places in the world? Sitting in my tent, looking at the sun rise over the Andes reminds me why, and this is a view that I will carry with me as I make the laborious climb to the summit.
As the morning skies cleared over Aconcagua it would be our last window of opportunity to summit. We altered our plan of ascent due to our level of fuel and food, and have planned a 5 day push to get up and over to the other side of the mountain. We would go from basecamp straight to MC-03, a high altitude 19,500 foot camp. Then the following day we would move to MC-04, our high camp at 21,500 feet before attempting to summit.
Making the journey to places in the world that have extreme climate conditions requires a mindset that acknowledges the capabilities of the weather and allows climate to dictate your personal level of success. Spending 4 days at basecamp was a difficult mental challenge for our team, and we had to maintain a level of preparedness at all times. We spent our days hiking surrounding peaks, organizing and cleaning gear, preparing our ascent plan, laughing, and always keeping a close eye on the large cloud hovering over the summit of Aconcagua. For the moment that cloud disappears it would be our small window to ascent high on the mountain quickly.
As the temperatures drop well below zero and the wind begin to exceed speeds of 50 mph, our ascent becomes the topic of discussion. Weather predictions from the bottom of the mountain show a system moving in capable of producing wind speeds over 70 mph and the consistent drop in temperature will freeze our water supply and put our team at a great risk of hypothermia, frost bite, etc. Currently we are at 17,500 feet and are going to retreat over 3,000 vertical feet back to basecamp.
It would be stealing if I did not give my guide Vern Tejas full credit for the phrase “oxygen is good, more is better”. As we climb from 15,500 to 17,500 feet it becomes imperative to breathe often and with intention so that the body is able to receive an adequate amount of oxygen. Failure to do so can lead to medical problems such as cerebral or pulmonary edema that can rapidly place one in critical condition.
Once away from the luxuries of basecamp life returns to the essentials; food, water, oxegon, and shelter. Daylight becomes a critical determinant for when and how the human body is able to function. As the sun sets over MC-01 at 15,500 ft we are forced to quickly retreat to our tents and insulated bags for warmth. As the sun rises we await the moment when the light will strike our tents and warm them to allow us to prepare for the day.
Before the climb, during the climb, and after the climb, every piece of equipment gets weighed and accounted for. Each individual on the team is responsible for their own personal gear as well as group gear. Maintaining a light weight team is one of the large challenges for high altitude mountaineering.
Basecamp offers a world within a world on the mountain. As I pursue the study of extreme climates, and places where people nor architecture are able to inhabit, basecamp integrates itself as the misfit. Here there is a large community of cooks, guides, porters, expedition staff, doctors, entrepreneur’s, and opportunists. This is the place of the mountain that offers the highest level of domesticity.
Quick agility on site was a key component to the project. This was several hours into the first night, and because the temperatures were still warm I was able to use fabric repair tape to mend the tears in the fly and inner tent. Over the next few days the sun would heat up the tape and tightly bond it to the fabric. This connection would be imperative for the tent to perform adequately high on the mountain.

Moments after I completed setting up my tent for the first night, a dust tornado appeared about 200 yards in the distance. It moved quickly through the valley of the high altitude desert and picked up a neighboring tent, launching the tent (North Face VE-25) and all of the rocks attached to its anchors through the air.

Aconcagua stands as the highest point in the America’s and Western hemisphere. The high altitude mountain is amidst ice, rock, cold skies, and winds that howl like a freight train roaring through the Andes. At times the best recording device can be the country’s blue and white flag that can be found flying proud at all elevations on the mountain.
On February 15, 2012 I started my trek into the Andes, relying on the tent I built for shelter against the extreme elements, with the hope that in several weeks time I would be standing on the summit of Aconcagua.

Over the past few weeks sewing has become a major mode of the fabrication process. The methodology for working has allowed for a blend between the digital and analog. It has not been a linear process, but an integrated one that incorporates highly articulated digital modeling software and analog means for construction using hand measurements and adjustments. Sewing is at the forefront of the hands on process, where it enables a high sense of craft and deliberate control over each piece of material. Every stitch has its own ability to generate the fabric form of the tent.

The initial test fit of the fly (which covers the inner tent) was successful. The proper fitting confirms that the double curvature was calculated correctly. Next step is to complete the inner tent, attach it to the base, and then complete the fly. Flight leaves at 3pm on Sunday Feb. 12, so no time to waste.

Shifting to full scale requires careful consideration for tolerances, especially with regards to the sewing offset for the ripstop nylon fabric. Currently the base with the reinforcements is complete, and now beginning to work on the inner tent construction.

The test has informed the next iteration of design about several modifications that need to be implemented. This includes widening the rear cross member, creating areas of ventilation on the top middle panel near the rear, inserting vents along the lower corner panels for exhaust ventilation, and change in seam length. These changes are being integrated into the final design and fabrication which is already under construction for the February 12 departure to Aconcagua where it will be tested in extreme conditions for 24 days.

Aconcagua is known for its extreme winds, and therefore a wind tunnel test was imperative to simulate these conditions and understand the accountability of the structure. The tent was able to sustain wind speeds ranging from 60-80 mph before minor tears occurred. The last test of the day challenged the efficacy of the design with wind speeds up to 122 mph which put the tent in complete failure, blowing out the back door and tearing apart both sides.
The video below records the last test of the day. The numbers being read off are referencing air velocity in feet per minute to an engineer that is reading back the wind speed in miles per hour. This is a rough cut, and the final video will be posted in late march

To ensure that the wind tunnel produces accurate testing results, the preparation is critical. The initial phase of preparation involves working with Aerospace engineers place bolts into model which secure it to the tunnel, and then review various tests that are going to be run so that the results desired are tested.

The pole design for this tent requires pre-bent rods creating curvature that can match with the digital model. This will enable the fabric to respond accurately, and with tension when it is set into the structure. The pole design was generated by the space required for interior movement of my body. Vertical height is given when sitting up is required and slope occurs near the feet. This creates an aerodynamic nose to orient into the high speed winds on Aconcagua.

The first design prototype (1/2″ = 1′ 0″ scale) is nearly 90% complete. The final touches will include guy line tension cords and stakes that will keep the fabric taught, and assist in keeping the tent rigid in high winds and extreme weather conditions. This is the model that will be tested in the Aerospace engineering wind tunnels on Thursday Feb. 2. A little work left to do and it will be ready for testing.

The use of digital modeling software and scripting to create accurate double curvature needs to constantly be reviewed and tested with regards to the fabrication and material constraints. These are conversations that occur daily, enabling the project to continue its fast track pace, and see fruition in the next week.

The design for the tent is generated from the scale and movement of my body, area of my pack, and size of my boots. The first step was to take simple measurements, and this was a revision of those measurements to ensure the proper interior dimensions before submitting poles for fabrication.
