The retirement system will also announce a new executive director next week.
The deferred compensation plan is seeking both record keeping and custodian services.
The commitment will help move the retirement system closer to its 30% non-core real estate target.
The plans currently work with general investment consultant Innovest Portfolio Solutions.
The position is a new one for the private equity firm.
The $300 million in total commitments went to existing managers.
Patrick O’Donnell joined the firm this week from BlackRock.
The commitments were approved by the plan’s private markets committee at a meeting yesterday and require full board approval later this month.
The plan expects to interview two finalists at its November investment committee meeting.
The incumbent consultant was awarded a new eight-year contract.
