FS20, Arena, Project, by Group 13 Triathlon Arena How do one stage a Triathlon? Usually, a competition takes place in the existing infrastructure of the city, neither needing a big tribune, nor a specific stage. However, the experience on the roadside stays a selective one, never able to really perceive the competition as a whole. In order to bring the Triathlon to one specific site, we took out fragments of the competition and introduced them as highlights in the arena. Also, the temporary character of a Triathlon should be turned into a long-term installation, which should not only serve for competition purposes, but also for training and leisure.  In the site plan you obtain a general idea of the arena, seeing the pathways leading into it, through it and out of it -  as well as continuous and closed routes. The two existing structures frame our arena in the longitudinal direction and simultaneously serve as entrance and exit situations. (1) The three disciplines perform on the three existing terraces which organize the competition naturally. The start will take place on the middle terrace, where the pool is located. After completing the 1.5km long swimming track, the athlete will move down a big staircase, heading for the changing zone. This area can be seen as an extension of the middle terrace and a connector to the existing building, forming also a centralized stage for this highlight. While the clock continuous to tick, the swimmer transforms into a racer by grabbing his bike and tackle the 40km cycle-route. Coming back into the arena and again through the changing zone, the last discipline, running, will succeed, a track of 10km length. Moving from the competition to the training, we wanted to give it a comparable importance, by creating a closed and conclusive space. (2) The form of the oval is inspired by the Stadium Domitian, where the loop also a major role. However, we also have the concept of transition which more correlates with the Sambodromo in Rio de Janeiro. This street-like stadium builds the stage of a bigger, traditional network. Therefore, we see our arena as a combination of the two typologies. Due to the different distances of the disciplines, various parts of Zurich can be reached. Not only does it connect geographically, but also socially. People who dwell near one of the routes can follow parts of the competition which gives us the opportunity to enlarge the audience beyond the stadium itself or even animate them to come to the arena. For the neighborhoods, this site can also be regarded as a landscape park since a competition is not the most frequent event. (3) In Switzerland, the weather of course is not always sunny and cloudless – thankfully! The rain allows plants to grow, brooks to run, colors to saturate and to see the manmade interventions in its bare form, searching its place in nature. (4) Our different intervention layers can also be seen in a more objective way, as layers that are placed over the existing. As a first step, we intend to “carpet” it with geotextiles, in order to tighten the ground and providing a base for the different surfaces. On top of the geotextiles, we place a permeable tartan track. The natural pool profits from the existing brook and does not need any chemicals since the plants clean the water themselves. The wooden structures are introduced as the last layer. On the one hand we have the stage for the changing zone in front of the building and on the other hand the structures for spectators alongside the pathways: These consist of a railing along the tartan track, a platform and a tower. (5) The tower serves a connector between the platform and the accessible target roof, where the swimming can be observed perfectly. It further provides a beautiful outlook onto the whole arena and the lake of Zurich. Within the target structures, the jury, press and also the changing rooms for the athletes are located. (6) In the cross section we show various spaces dedicated for our spectators. Our main tribune will be located within the existing building. However, a special feature of our arena is, that the spectators are invited to change their location according to the state of competition and interest, since a Triathlon lasts for more than two hours. (7) Zooming in, we analyzed the structural principles of the staircase, foundation, tartan track and natural pool, which appear multiple times in our arena. (8) In the longitudinal section, the opposed existing buildings take the form of a bracket. However, their functioning has a more porous character, allowing incoming and leaving flows. (9) The rhythmical columns do not only serve as supports but also as bicycle racks. The bridge docks on the building and the middle storage will be opened. Therefore, we do not change the existing extensively. The program however will be more diverse, which leads to a bigger public use. We extend the existing restaurant and add a fitness centre in the lowest storage for training.  The newly designed Triathlon arena guarantees a clear overview for spectators, allowing closer and recurring interactions with the athletes. This gives them an unforgettable unique sport experience. On top of this, the site also serves as a place of retreat, surrounded by the beautiful landscape. It is a place for everyone – athletes, fans, strollers, families or even animals. Diversity is guaranteed in all dimensions.

FS20, Arena, Project, by group 13 IN-BETWEEN   The notion “In between” has both a spatial and a temporal component. Our arena is framed by two opposed existing buildings. The room in between those objects consists of tree terraces on which a Triathlon can take place.   This spatial component can also be seen in the collage of the Arena traffic but more importantly, it takes the organization of the competition and the different flows of the athletes into consideration. Every time they enter the arena, they pass under the shooting targets. But nevertheless, it raises the question of what happens between those disciplines and with it the question of the temporal component of the “in-between”. The time will not be stopped during changeovers, which gives those parts an importance as well. Those hectic moments, when the adrenaline raises, can be observed by entering the front gate of our arena. (1)  What the spectator sees first after passing the front building is the whole arena on one view. This overview is shown in a top down manner on the site plan. The athletes start in the middle by swimming 1.5 km. Then they grab their bikes on the left terrace, which has special significance due to its asphalted surface. It is where the changing zone is located with its bicycle stands and the arrayed running shoes. Therefore, they enter this zone twice. Before passing the finishing line, the athletes have their home stretch on the other side of the tree avenue where the spectators have a limited view. Then they enter the arena for the last time by running under the shooting target onto the lowest terrace where they are celebrated by the spectators. Those can access this last street through a bridge from the building, coming from an observing place to interactive one. (2)  A street that is being staged can be found in Rio de Janeiro on a much larger scale with the Sambodromo. It provides a framework to the highlight of the Samba tradition, the Carnival. But this one street is embedded in a network of other streets where the Carnival has actually its origin. Also, a Triathlon is usually observed from the street, never having an overview of the whole competition. This aspect is shown in the drawing “Audience beyond”. All the routes are laid out, showing also the directly attached neighborhoods, from where parts of the competition can be followed. (3, 4) Back to the site, we now want to focus on the spectators of the arena and their relation to the athletes. The façade of the first story of the existing building will be opened, creating a loggia-like space. The rhythm of the wooden columns in the facade is pushed along the raised pathway leading to the already mentioned lowest terrace. The crossing of spectator and athlete builds a key moment in this leaving zone of the arena and is further characterized by the existing clock. 300m away the athletes make themselves ready in the shooting target, also looking on the clock. (5) Having a look on the different perspectives of the spectators, one can further look at the cross section. In the background, one can see the top down situation from the existing building whereas there is a more informal “tribune” next to the forest on the left – there, people are able to sit on the existing slope and really feel the linear functioning of the competition. Last but not least, we have this typical “street-experience” on the right. There, one is at the same height as the athlete and really feels part! Also, the tree levels are once again illustrated, focusing on the different surfaces and soil structures (not yet fully developed in the drawing). (6) The entire dimension of this indicated intervention should be shown in our structural model. We intend to do an extensive terrain renovation based on geotextiles. This should strengthen the ground and prevent it from becoming muddy during high uses. (7) All the processes and material consumptions are further demonstrated in the Energy Drawing. It clarifies that the excavated soil from the pool can be used for the ramps next to the building that are part of the asphalted street going through the arena. Concerning the surface of this street (which is also built on geotextiles) a special drain-asphalt is being suggested, as it is water-permeable. Going from the ground to what is built upon it, the fabrication and application of the wooden structures are being explored in the drawing. (8) While building such structures as an asphalted street and bicycle stands, we simultaneously thought about the uses aside from hosting a Triathlon competition. We believe that with our design, the whole arena has also the qualities for a public park. Providing the facilities to come by bicycle, people can have a short swim and picnic on one of the terraces. A nice get-away from the city. (9)  The choice of building a clock as our character model has different aspects. One of them was just mentioned before by the double use of our arena, so the site can be used around the clock. It also once again highlights the temporal aspect of our overall concept and becomes a spatial element through the huge existing clock on the site.

Workshop OMMX

FS20, Arena, Project, by Group 13 In-between  Rethinking our structural thesis, we went back to Friesenberg and took a closer look at its architectural language. We came across houses with pergolas, balconies, access balconies and front yards. In the Atlas these settlements were already analyzed quite well with detailed drawings and pictures. As a Triathlon usually finds its way through several neighborhoods and city quarters, it is not too far-fetched to make use of some specific elements for the arena itself. In this way, we create a tighter interplay between dwelling and competition. Working with the existing building, we can think of attaching an access balcony on the south façade for the spectators. Furthermore, this structure can be extended as a detached pathway along the arena that connects the building with the opposed shooting target. This intervention is less about creating tribunes, but a space where spectators can move along and get different views onto the athletes. For the balcony-pathway, we want to use the method of “Baubotanik”. We were so fascinated of the functioning and think that it merges perfectly into our project. With this method the aspect of time and transformation becomes an important component of our arena. In the beginning, the structure is one out of steel but over the year, the trees will overtake the structure and turn into the structure itself. At this stage, the vertical iron posts can be removed and reused for another purpose.  Moving the attention to the athletes and their pathways, we come to the issue of the terrain and the treatment of its surface. In order to guarantee a durable ground while so many athletes run or cycle on top of it, we thought of using Geotextiles. It should strengthen the soil and keep it in place while the water can still drain through its fibers.  Furthermore, the excavated soil from the pool area will be used to form the two ramps in front of the building, probably also supported with some Geotextiles. This area-wide move can collectively be seen as a renovation of the whole terrain while maintaining its characteristic shape.

FS20, Arena, Project, by group 13 IN-BETWEEN   The special feature of the Triathlon, besides that it is a combined event, is that the changeovers, or rather the “In-between”, are just as important as the three different disciplines. Our Triathlon-Stadium is situated on the stretched-out levels of the Albisgütli shooting range and framed by the two existing structures of the shooting association. According to these linear conditions and the terracing of the site, we create three different stages: one for the swimming, another for the changeovers and a third for the home stretch. As the existing beams of the shooting target resemble the typical sports start and finishing line, the athletes will pass them every time they enter or, accordingly for the home stretch, leave the stadium. In the collage of the Arena traffic those flows are shown in an abstract manner, showing the traffic of the spectators in-between the traffic of the athletes. (1) Multiple attendee moving in and through the Triathlon arena resemble the event of the Carnival staged in the Sambodromo (Rio de Janeiro, Brasil) where the Samba-dancer and Samba-lovers gather. With all its participants, different scales coming together and form a multilayer construct that also goes beyond the boundaries of the stadium itself. (2) By introducing a Triathlon-Stadium, we are also confronted with different scale levels: First and foremost, the athlete enters the swimming discipline of 1.5km that can be entirely accomplished on site. Afterwards, the cycling track of 40km follows, which leads out of the arena through the larger surrounding of Friesenberg, including the city of Zurich as well. Finally, the running path of 10km connects the stadium to its closer surroundings following the beautiful Panoramaweg. Not only does it connect geographically, but also socially. People who dwell near one of the routes can follow parts of the competition from their own living unit. This gives us the opportunity to enlarge the audience beyond the stadium itself. (3) Coming back to the arena, we organized the whole site accordingly to the given conditions. Thanks to the different terrace levels, we achieve a clear distinction between the different zones and create a sequence in the competition that resembles an ascent. Additionally, in-between those zones we place the tribunes in the existing slopes of the terrain. These, one can enter from the existing building through arched bridges. Along with its function as a stadium where competitions can take place, the site should also serve as a training slot. Next to the arena, we intend to locate a training centre, where athletes can train also indoor. Additionally, a hotel can be included for international visits. (4) Focusing now on another aspect of the arena, leads us to the resources and processes behind the directly visible elements. Working with existing structures, we try to keep the interventions as small as possible. The shooting target will be determined to the athletes and the needed facilities while the first upper floor of the other existing building serves as a gate for the spectators. Making use of local materials, we use the soil, the wood from the forest and the brook. The water is led straight into our natural pool. The excavated material (loam) can be used to form adobe bricks for the tribunes. Some of them will further be burnt for the higher structures of the arched bridges that are just docking on the existing building. (5) For the better understanding of the terrain with all its slopes, we built the site out of soil and loam, also to get to know some of our intended building materials for the arena. (6)  The cross section focuses on the structures that are integrated in the terrain of the terracing. The swimming area lays between a filter- and regeneration zone, which guarantee a natural cleaning process through the plants. The adobe bricks seem as if they grow out of the ground, providing the base of the sitting area which is additionally covered with wooden panels. Such wooden panels are also suggested for the changing zone as they guarantee a sustainable treatment of the surface. (7) Looking at the longitudinal section of the whole arena, the location of the tribunes is demonstrated as an in-between structure of two existing elements that affect one another strongly. The shooting target with its opposed building is framing the whole arena while the tribunes serve as a connection between the two. (8)  As a spectator you are part of this connection, observing the athletes coming into the arena, changing the discipline and leaving the arena again. But it’s not only about being part but being right IN-BETWEEN and observing the things that happen IN-BETWEEN.
