Its first match was played on 25 December of the same year against another historic Catalan rugby club team, UE Santboiana.

In the late 1950s,the former founding players led by Zarraluqui and Ciscar, started the difficult task of raising the club.

The club ended two times runner-up of 2 ª División Nacional and achieved a championship title in the same category.

With the end of the Franco Regime, the club kept going forward and in 1979, two new sections were created: the women's team, which had a brief two-year period and the foundations for the future rugby school started to be laid.

The lesser level categories, nonetheless, managed to win several Catalan Championships and the women's section of the club was recreated.

In these years, the definitive folding of the CN Montjuïc rugby section caused the arrival of several players with which the club took a new impulse.

In this same year, with a group of very young players, BUC won the Catalan Championship without losing any match in the league, winning the promotion to Primera Nacional.
