Yes. A requirement of the Part 2 Proposal, which is due by noon (central) on Wednesday, October 4, 2017 (except for your bids), is to provide an original executed Letter of Credit in an amount sufficient to support your Bids. If the Letter of Credit is not received by that time, your Part 2 Proposal will be automatically deficient. You will receive a deficiency notice from the Procurement Administrator that will include a deadline for curing such deficiency. If such notice is your first deficiency notice regarding your Part 2 Proposal, you will have generally two (2) business days to provide the Letter of Credit. Additional deficiency notices generally provide less time for providing additional information or curing deficiencies.
