3 SITES IN VIANA In 3 sites along Viana cross-section we have

looked at how the differerent architectural interventions can be played out through re-acting to existing qualities and acknowledg-ing local potential.

SITE 1The Informal Market Place

THE INFORMAL MARKET PLACE

AN EXISTING MARKET

Today the market is an open space in the musseque area, privately owned. We were not able to get any proper pictures from the site, because the owner was not present the day we were there. Because it is a private area, the police do not chase the informal sellers away. Most people here sell food products -vegetables, fruits, grilled meat and fish -but also clothes and different household equipments.

The Bairro station serves a number of approxomately 2500 people within the connecting radius of 250 meters. With the doubling it will be 5000 people.

The market owner was not accessible to let us take pictures of the market. These are the pictures we got from the site by photographing some people we met.

ADDED PROGRAM

Existing market and it’s parasol roof Offering a permanent roof, including program on top

EXISTING MARKET

The market has a limited area, and each seller are free to choose a site every day. A small amount is given to the ground owner as a monthly rent.

Every seller provides it’s own shadow.

OFFERED GRID/ ROOF

The architecture offered at the ground should be a general, open space, promoting informal usage and possibilities of change during time.

FREEDOM TO BUILD

Within the grid, informal (or more formal) salesstations could be built. Each seller could built storage

If the grid is closed off at night, it will be safer to invest in more permanent sales-structures, including freezers etc for the sellers.

VIANA STATION HUB

REGISTRATIONS

LARGE OPEN SPACE NEXT TO VIANA TRAIN STATION. BECOMES FLOODED DURING HEAVY RAIN.

VIANA STATION MARKET LOGIC TRAFFIC FLOODING

“The market has existed probably for 20 years, and it is difficult to just leave this marketplace when we do not have any other place to turn to. This is the best location for a market as there is such a large circulation of people and concentration of transport networks.”Iana, market vendor.

BRIDGING

Placing public programmes in the crossing structure will at-tract and give people a reason to use the bridge in favour of crossing on ground level (which is a quicker option).

The public space added to the crossing bridge in the form of open flexible rooms will give room for the existing mar-ket, allowing it to claim it’s space in the hub of traffic.

The new structure will bridge the physical divide between the two sides of Viana. It provides pedestrian infrastructure, and creates an active civic space.

TRAFFIC REGISTRATION

30 minutes at Viana station, counting the volumes of traffic.

Chapa traffic counts for about half or one third compared to the private car’s traffic. Most cars features only one or two persons, while the chapas can take until 14 persons. Counting people on the road, most people in this area use

chapa as their transportation.

The Butterfly Effect

“The butterfly effect is a metaphor that encapsulates the concept of sensitive dependence on initial conditions in chaos theory; namely, a small change at one place in a complex system can have large effects elsewhere. Although this may appear to be an esoteric and unusual behavior, it is exhibited by very simple systems: for example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position. The butterfly effect is a common trope in fiction when presenting scenarios involving time travel and with “what if ” cases where one storyline diverges at the moment of a seemingly minor event resulting in two significantly different outcomes.”

Wikipedia, 2011

Viana is divided physically by the railway and the highway. A crossing bridge has been set up for pedes-trians, but is not widely used. With people crossing the highly trafficated highway, the situation is critical in terms of safety concerns.
