Weeks before the event the Ministry of Housing published a booklet in the official press along with a blueprint plan of the stadium. Sixty pages contained a long list of summoned people divided into the 17 communes of Greater Santiago, and in which more than 60 assorted slums were represented through various shantytowns and neighbourhoods. Each commune was then assigned a specific sector within the stadium (eg, 1, 2, 4-B, 1ª, etc), and a precise access door in the stand (eg, SS, RR, Q, J, HH, etc) which in effect created a complete grammar and aesthetic code connecting the building with the surrounding city.
