We are unable to tell exactly to which slide your question refers but we assume that you are referring to the structure of the proposal submission process (slide 20).  This submission process is generally the same across all procurement events held by the IPA.  There has been no change to this structure since the Initial Forward Procurements.

Proposal requirements, however, may change.  In particular, the IPA is seeking input on the level of pre-bid collateral and on an appropriate milestone to use to assess project maturity.  Feedback regarding the level of pre-bid collateral is requested under Topic 2 in the IPA’s Request for Comments and feedback regarding an appropriate assessment of project maturity is requested under Topic 4.
