Which of the following is considered good ethical conduct in bidding?

Good ethical conduct in bidding is characterized by transparency, fairness, and integrity. In this context, none of the actions listed—bid shopping, bid peddling, or bid rigging—reflects these principles.

Bid shopping refers to the practice where a contractor solicits lower bids from subcontractors after receiving an initial bid, often undermining the original bidders and potentially leading to conflicts and mistrust. This approach lacks fairness and can damage the collaborative relationships essential in construction.

Bid peddling involves a subcontractor approaching a contractor after the bidding process to offer a lower price than what was initially submitted. This tactic also creates an unfair competitive advantage and can disrupt the integrity of the bidding process, as it encourages last-minute negotiations that do not reflect the initial proposals.

Bid rigging is an unethical agreement between competitors to manipulate the bidding process, typically resulting in inflated prices and a lack of competition. This practices not only violate ethical standards but also legal regulations, leading to significant penalties.

Given this context, it is clear that none of the actions described in the choices represent good ethical conduct in bidding. The correct answer, which recognizes that all the options are unethical practices, underscores the importance of maintaining integrity and fairness in the bidding process.
