The goal of the project was to measure the topography of an area located in Prilly-Malley, Lausanne. The first thing we did was scaling the plan that we were given from 1:1500 to 1:132. When the plan was done, we divided it using 7 lines which were assigned to groups of 2. Each group then wen on the site in order to measure the topography following their own line.
In order to measure the topography of each line, we imagined and crafted a measurement tool. The goal was to measure approximately 30 heights on the line we had chosen, the level zero being the floor of house 2. We came up with different ideas that allowed everybody to make their measures.
Once we had the measures, we translated the 7 lines into one smaller section, in order to create 8 equidistant stripes. On each line, we also marked every point of measure with its respective height (according to the level of house 2). When the stripes were delimitated, we were ready to begin the drawing of the stripes' plan and elevation.
The triangles that can be seen on the top of the drawing above are formed by connecting the points that we measured on the top line with the ones on the bottom line of the stripe. We used geometry in order to transform these triangles from a bi-dimentional view to a tri-dimentional view. On top of the drawing, the stripe is therefore the 3D shape of the triangles that make altogether the structure of our mould. In other words, these triangles are the shape of the model of the area. We then proceeded to cutting the triangles into cardboard in order to build the mould. We also cut the outline of the elevation of the area.
Finally, we assembled every piece of cardboard in order to have the final mould. When it was ready, we could cast using plaster. When each groups had casted, we were able to align every stripes and the final model was completed.
