Forms

As acts of corruption

  • Change order abuse occurs when a contractor colludes with project officials, wins a low bid, and asks to change the contract afterwards. That is approved by officials, resulting in a much higher bid being retroactively approved.
  • Bidder exclusion allows project officials to essentially choose their bid. There are multiple methods to achieve that, like the following:
    • Instituting unreasonable qualification parameters, excluding non-preferred firms, or effectuating the same by shortening the time of acceptance periods for new bids following a request.
    • Advertising projects to select bidders or bidding markets, thereby reducing publicity of bid procurement.
    • Bundling of contracts to exclude bidders.
    • Coercion and intimidation can also be used, as well as the simple rejection of individual bids over trivial matters.
  • Purchase splitting to reduce the minimum bid amount. That functions as contracts are split up to reduce the actual procurement amount and keep it under a threshold value. That reduces competitive bidding and enables less oversight at the project level as bid prices drop and kickbacks can be allotted.
  • Leaking of bid information, which requires a relationship of some degree between the project and a bidder as the bidder is handed information to gain an unfair advantage.
  • Bid manipulation is another method for officials to choose the bidder of their choice but occurs after receipt of bids. The methods for this would include either changing bid parameters, evaluation processes, or other activity to effectively select the bidder of choice.
  • Rigged Specifications allow more bidder exclusion by officials by either tailoring requests to individual bidders or creating a vague criterion to reasonably choose a preferred bidder.
  • Unbalanced bidding involves high bid prices for commencing phases of development and low prices for later stages. That effectively increases the flow of funds for the bidding firm. This occurs when bidders cite high prices for items, intending to raise the number of units and purchase them at a competitive rate while simultaneously skimming profits from the artificially high bid price. Additionally, bidders may give low quotes for non-necessary items (knowledge gained through collusion or experience) to disadvantage other firms as their bid amount is more competitive. This also serves to increase the cost of entry for new firms.
  • Unjustified sole source awards are bids chosen on criteria unrelated to their competitiveness. That can be performed blatantly, by falsifying bids, or by price splitting.

Within a cartel

  • Bid suppression collusion occurs when some of the conspirators agree not to submit bids to allow another conspirator to win the contract.
  • Complementary bidding, also known as cover bidding or courtesy bidding, occurs when some of the bidders agree to submit bids that are intended to be unsuccessful so that another conspirator can win the contract. For example, the cover bids might contain prices that are uncompetitive in relation to the prices submitted by the conspirator, who is designated to win the contract, or the cover bids might contain conditions that the conspirators know to be unacceptable to the agency calling for the bids.
  • Bid rotation occurs when bidders take turns being the designated successful bidder. For example, each conspirator is designated to be the successful bidder on a certain contract, with conspirators designated to win other contracts. That is a form of market allocation in which the conspirators allocate or apportion markets, products, customers or geographic territories among themselves. This is then divided up such that each will get a "fair share" of the total business, without truly having to compete with the others for that business.
  • Bid delegation can be a factor fostering the presence of bid rigging; for instance, it is the case of marketing agencies that bid for the same ad space on behalf of different and competing agents.).

As a seller, auctioneer or official

  • Phantom bids or shill bids are false bids to trick a legitimate bidder into bidding more than would have otherwise been the case. The seller or auctioneer hires confederates to call out the phantom bids. If the phantom bid is the winner, the lot is hidden and comes back around for a second auction, or the second-highest legitimate bidder is informed that the first bidder was unable to make payment. In online auctions, the latter ruse is pulled via a (secretly illegitimate) "second-chance offer." Sniping is a legitimate bidder's best chance to foil a shill bidder who aims to drive up the price artificially.
  • Buy-back is the strategy in which the auctioneer or seller bids on a lot and buys it back to protect it from being sold to the highest bidder for an insufficient price. That is fraud if the auction is advertised as an absolute auction, meaning that there are no reserve bids.
  • Phantom auctions, in the real estate industry, may occur when the bank "tentatively" auctions a foreclosed home and gives bidders an option to give "preliminary bids" for homes that are not yet authorized for auction. If the reserve bids are not met, the home is updated as "never was available for auction" even though bids were received. Some houses are auctioned at fire-sale prices, and the auctions are closed before the auction was formally announced. Investors rush to get in their preliminary bids before the house is technically up for auction. Bidders fear losing options, so it results in more bids, and naturally, higher prices. If bidders fail to reach the target bids, the item is never available for auction. Banks do that because if they unloaded all of their toxic assets at once, the housing market would collapse, which causes foreclosed homes to be dribbled out with phantom auctions.

Those forms of bid rigging can occur together, and two or more of the practices could occur at the same time. For example, if one member of the bidding ring is designated to win a particular contract, that bidder's conspirators could avoid winning by not bidding ("bid suppression") or by submitting a high bid ("cover bidding").
