For 29.53—the imposing piece by artist Patrick Bernatchez—Unigesco was commissioned to manage both design and installation on behalf of the City of Montréal. This work, representing the duration of a complete lunar cycle, i.e., 29.53 days, is made up of two cast-in-place concrete walls supporting an imposing two-sided prefabricated concrete structure with a highly complex shape. One of the faces represents a scale model (1:2000) of the hidden face of the moon, while the other is a climbing wall. This magnificent sculpture towers over the Université de Montréal’s Campus MIL.
