Planning in process: AORTA as a new instrument for the upgrading of informal settlements in developing countries
Furthermore, all used items are made on site and produced out of low-cost materials which
are easily disposable in the operational area.
a. loudspeaker double core cable b. car grille c. car air filter d. old pharmaceuticals e. sponge brush f. beverage can g. eraser h. plastic wine bottle sealing i. sponge j. electronic component
k. cork l. charcoal m. used computer keyboard n. styrodur m. styrofoam p. wax
Fig. 4: Material proposals
After all dwellings have been rebuilt in the model, existing infrastructure has to be
symbolized and decisive points of special interest displayed. As streets and foot paths can be
seen in the aerial photograph, just important elements for the daily life are accentuated, e.g.
water access points, bus stops, groceries, schools, dumping places etc. Therefore a set of icons
has been developed, precise enough to be understood by everyone, abstract enough to be
grasped very quickly. This icon-set is extendable or modifiable by the planning crew to adapt
to the prevalent imagination of the archetype. A first set of proposals can be printed out of the
internet.
4.3 Intervening
When the status quo is mapped sufficiently, people can start to give several settings a try.
Therefore the “AORTA toolbox” holds various elements ready to be pricked into the model.
a. community-centre b. orphanage-module c. cooling-device d. internet-box e. bike-repair f. medical-centre g. community-kitchen h. bus-stop i. roof-outstanding j. AORTA
Fig. 5: Selection of prepared add-on items
Different add-ons are proposed to be made out of different materials. To underline the specific
intervention, symbols from the icon-set are pricked on top of the elements. Now the user can
simulate different scenarios, figuring out the correlation between each intervention step and
realizing the direct consequences for him and his neighborhood.
