Construction bidding is meant to be a structured, competitive process where contractors and subcontractors submit their best prices based on clear project requirements. In theory, it promotes efficiency, transparency, and value. In practice, however, ethical gray areas often emerge : especially when pressure to win projects collides with tight margins.
Among the most controversial practices in the industry are bid shopping and bid peddling. While some may view them as strategic tactics, many professionals consider them unethical behaviors that undermine trust, distort competition, and ultimately harm project outcomes.
What Is Bid Shopping?
Bid shopping occurs after bids have been submitted, typically when a general contractor uses a subcontractor’s quoted price as leverage to negotiate lower prices from other subcontractors.
Example:
A subcontractor submits a competitive bid of $1 million. The general contractor then approaches other subcontractors and says, “Can you beat $1 million?”—even though the original bidder submitted their price in good faith.
Why It’s Problematic:
- Breaches trust between contractors and subcontractors
- Discourages subcontractors from submitting their best price upfront
- Can lead to lower quality work if subcontractors cut corners to meet reduced pricing
What Is Bid Peddling?
Bid peddling is the flip side—and happens before or during bid submission. In this case, subcontractors actively approach general contractors offering lower prices than their competitors, often after learning others’ pricing.
Example:
A subcontractor hears that another firm is bidding at $1.1 million and quickly offers $950,000 to undercut them—sometimes without fully understanding the project scope.
Why It’s Problematic:
- Encourages a “race to the bottom” in pricing
- Increases the risk of unrealistic bids and future claims
- Undermines the integrity of the bidding process
The Broader Impact on the Industry
Both practices create a cycle of distrust:
- Subcontractors inflate bids to protect themselves from being shopped
- General contractors become skeptical of pricing accuracy
- Owners may receive distorted project costs
Over time, this erodes collaboration and can lead to:
- Increased disputes and claims
- Compromised project quality
- Reduced long-term partnerships
What Does Fair Play Look Like?
Ethical construction bidding isn’t just about following rules—it’s about maintaining professional integrity.
Best practices include:
- Honoring submitted bids: Award work to subcontractors whose bids were used in the final pricing
- Clear communication: Avoid disclosing competing bids or using them as leverage
- Transparent evaluation: Consider qualifications, experience, and reliability—not just price
- Building relationships: Focus on long-term partnerships rather than short-term gains
Some organizations and contracts even include anti-bid-shopping clauses to protect all parties and preserve fairness.
Why Ethics Matter More Than Ever
In a highly competitive market, it’s tempting to justify aggressive tactics. But ethical shortcuts often lead to long-term consequences—damaged reputations, strained relationships, and project risks.
Contractors who commit to fair play tend to:
- Attract more reliable subcontractors
- Receive more accurate and competitive bids
- Deliver higher-quality projects
In the end, trust becomes a competitive advantage.
The Auction with Hidden Cards
Imagine a card game where players submit their best hands face down. Instead of playing fairly, one player secretly peeks at another’s cards and uses that information to force others to change their hands.
At first, it might seem like a clever move—but soon, no one trusts the game. Players start hiding information, bluffing excessively, or refusing to play altogether.
That’s what bid shopping and bid peddling do to construction bidding—they turn a structured competition into a game of manipulation, where trust disappears and everyone loses.
Ethical issues like bid shopping and bid peddling may offer short-term advantages, but they weaken the foundation of the construction bidding process. They distort pricing, damage relationships, and increase project risks.
Fair play, on the other hand, promotes transparency, trust, and long-term success. In an industry built on coordination and reliability, ethical bidding isn’t just the right thing to do : it’s the smart thing to do.
