Bid assurance collateral is due by noon (central) on Wednesday, August 23, 2017. If bid assurance collateral is not submitted at that time, any information you can provide on the timing of submission would be appreciated.  If you submit scans then the Companies can evaluate whether the Pre-Bid Letters of Credit are acceptable.  Nevertheless, your Part 2 Proposal will be deficient if bid assurance collateral in its final executed form is not provided by the deadline.  You will receive a deficiency notice from the Procurement Administrator that will include a deadline for curing such deficiency.
