A centre back, Biava started his career with the Leffe youth team, before moving to newly promoted Serie D team Albinese in 1995. During his time with Albinese before the 1998 merger with the Leffe to found AlbinoLeffe, Biava achieved a promotion to Serie C2 in 1997. In 1998–99, Biava helped AlbinoLeffe to ensure promotion to Serie C1. After a one-year loan at Serie C2 side Biellese, Biava returned to AlbinoLeffe in 2001, and was part of the team that won the promotion playoffs in 2003, thus ensuring them a Serie B place.
In 2003–04, Biava marked his Serie B debut, and scored the goal which ensured the first AlbinoLeffe victory in the league, a 1–0 win to Fiorentina.
His impressive performances in the league provoked interest from ambitious Serie B club Palermo, which signed him during the January 2004 transfer window. Biava immediately gained a stable place in the regular lineup, forming a tough defensive line together with Pietro Accardi and leading the rosanero back to Serie A after over 30 years.
Biava was confirmed by head coach Francesco Guidolin as a key player during the 2004–05 season, coincidentally his first season in the top flight, which ended with a historical first qualification for Palermo in the UEFA Cup. However he did not confirm his impressive performances in the following season, where he was mostly featured as backup player. With Guidolin back at the helm of Palermo in 2006–07, Biava regained a more important role in the Palermo squad, returning to play at his usual levels.
During the summer 2007, Biava refused an offer from his childhood team Atalanta, preferring instead to stay at Palermo despite the club management could not ensure him a place as a regular. He successively agreed a contract extension, meaning he will play with the rosanero until June 2009.
Nonetheless, in June 2008 he was sold to Genoa for €500,000, as part of Cesare Bovo deal. where he quickly established himself as a regular for the rossoblu in their impressive 2008–09 Serie A campaign ended in fifth place, partnered with Salvatore Bocchetti and/or Matteo Ferrari. He often partnered with Bocchetti for the first half of 2009–10 season but in January faced competition with new signing Dario Dainelli, in although the coach preferred 3–5–2 formation with 3 centre defenders and 2 wing-backs.
On 1 February 2010, Biava joined to Lazio for €0.8 million (but including other cost, made Lazio paid €1.04M). and along with new signing André Dias, became the backbone of Lazio that survived in relegation battle (he played 11 starts for Lazio in 2009–10 season) and good performance in 2010–11 season, which the team concerned lesser goal and finished as the runner-up before the winter break (round 17).
