The Host Acknowledgement is required only for the new systems and it is due by the Part 1 Date. If the document is not available at that time, the Bidder must justify this omission in the Part 1 Proposal. The Bidder will then be given more time to provide the document within the Part 2 Window. However, in no event will a Bidder be allowed to submit the Host Acknowledgment or to complete any other missing information regarding its systems after 12 PM (noon) CPT on the third business day prior to the Bid Date.
