Please note that all "Invitations to Bid" after July 1, 2009 have two dates included in their filename. The first of these dates is the date the invitation was published to the media; the second date is the latest closing date in the invitation ( each invitation may have multiple bids ---- each with their own bid deadline within this date range ). Adjacent "Invitation to Bid" notices may have overlapping date ranges, so be sure to examine check each "Invitation to Bid" notice that covers the date range you are interested in. Also remember to check the December "Invitation to Bid" notices of the prior year when looking for bids with deadlines in January.
