Sala São Paulo, São Paulo, Brazil
Sala São Paulo concert hall was inaugurated
in 1999 with the Mahler Second Symphony, conducted by John Neschling.
In 1996 Artec was invited to determine the feasibility of a new
permanent home for the São
Paulo Symphony Orchestra. Artec determined that an open-air
courtyard inside the Estaçao Sorrocabana Ferrovial Júlio
Prestes - the central railway station - would be the best, and most
appropriate space to be renovated for concert hall use.
The active rail lines that still operated within
a hundred feet of the facility presented a major challenge. The
use of a "floating slab" was Artec's choice to prevent
this, and any other vibration-born noise, from entering the building.
For this conversion/renovation, Artec designed
one of the world's first motor-operated adjustable acoustic ceilings.
It is divided into fifteen individually controlled panels that allow
the shape and height of the ceiling to be changed, adjusting the
acoustic environment to match the performance.
The main floor of the 1600-seat venue is a flat
floor with demountable seating. A parterre of fixed seating surrounds
the main floor. A rear balcony and balcony boxes were installed
around and behind the concert platform, and in the audience chamber.
A second level of balcony seating boxes was created from the existing
first floor corridor.
Artec provided Design and Planning services covering
Phase services, Auditorium
Performance Equipment Systems Design and Background Noise
and Vibration Control consulting for Sala São Paulo.
The original Estaçao Sorrocabana Ferrovial Júlio Prestes
was designed by the noted Brazilian architect Neves. São
Paulo's Nelson Dupré was the architect for its conversion
to a concert hall.
