Last week study Calatrava has officially informed the technicians of the City of Venice about the most suitable methods to solve the problem of particular steps of the deck of Constitution , the cause of complaints in the press. The same study points out a note from the architect Santiago Calatrava.
As known - says the statement - some steps are twice as wide as those above and those below. The double steps precisely mark the change of width of the treads. This is in compliance with the legislation, but also because the majority of Venetian bridges is like that. The variation of kicks is in fact the result of the profile characteristic of semi-arch bridges in Venice to allow the passage of boats. At these points the floor of the bridge is divided into three lanes: the side-slip mat glass, center stone (trachyte).
According to project manager engineer Salvatore Vento - continues the statement - the more distracted or people with sight problems can not immediately perceive the change of rhythm going and is therefore likely to fall. This is clearly an issue that belongs to the perceptual field and has, therefore, entirely subjective character.
Request Wind study engineer Calatrava has proposed, however, suffered the most appropriate solution: it is simply to replace the 24 treads concerned with glass treads similar trachyte .
