- Do you know or suspect, or have you heard, that bids are being manipulated
- Winning bid is just under the next lowest bid
- Bid is too close to budget, estimate or preferred solution
- Inadequate bidding procedures, e.g., acceptance of late bids, non-public bid openings, taking breaks during the bid opening (to provide the opportunity to share the content of certain bids and to amend others), etc.
- Late bidder is the winning bidder
- A questionable agent, “consultant” or “middleman” is involved in the bidding process
- Project officials and a bidder communicate or meet privately during the bidding process
- Are controls and procedures to prevent the manipulation of bids in place and enforced?
