Many Haas-Bioroid: Engineering the Future decks focus on the appeal of fast-advance and tend to float the odd single-pointer agendas, and since HB's core identity is geared towards generating money Gila Hands Arcology is often ignored and replaced with Chronos Project. So if you're looking for the odd 1-pointer to slot into your deck, why would you chose Director Haas' Pet Project over Chronos Project?
The first thought is to recur the assets and/or upgrades you may have lost to the archives, namely Caprice Nisei, Ash 2X3ZB9CY, Adonis Campaign / Eve Campaign or Breaker Bay Grid.
An alternative thought is to consider how strong your meta is with Apocalypse. Typically your opponent's turn will be spent firing the Apocolypse, with the hopes to reap rewards on the next turn. Using Biotic Labor and Director Haas' Pet Project you can score out this agenda and recover a scoring remote before your opponent can establish a breaker suite; however, this will leave your centrals at the mercy of the Runner, but that's the trade-off.
So consider DHPP if you're in need of board-state acceleration / recovery; if you're shy of Team Sponsorships. Situational, but being able to effectively Interns an Ash, Caprice and Turing off of a single score can be powerful, and if you 'do' have all 3 Team Sponsorships rezed, it gets even better.
