The retirement system is also slated to vote on its general investment consultant search next month.
The plan interviewed three firms for a $7.5 million mandate.
The search is for an open-end private infrastructure strategy.
The retirement fund disclosed $85 million in recent commitments across private equity and real assets.
The plan is seeking active and passive funds to handle $1.35 billion.
The plan approved $350 million in commitments with GPs at a meeting last week.
The latest fund more than doubled the fundraise of its inaugural fund, which closed in 2022.
The retirement plan approved a private infrastructure manager search to handle a potential 4% target allocation in December.
The trust added targets of 3% each to listed infrastructure and listed REITs in the fourth quarter.
The retirement system also concluded its general investment consultant search in January.
