I have spent my career on both sides of a construction contract. I installed roofing systems with my own hands before I moved into the office to run the business. That gives me a view that most commentators on federal construction policy simply do not have.

I know what a wage determination does to a bid because I have priced jobs. I know what compliance paperwork does to a site because I have stood on one.

And I can tell you this with confidence: the official numbers on the Davis-Bacon Act are wrong. The government says the act inflates federal construction costs by roughly 10%. From where I sit, once you account for how contractors actually price risk, the true figure is at least 30%.

Here is how I get to that number.

What the Government Admits, and What It Leaves Out

Start with what the Department of Labor itself concedes. A 2008 Beacon Hill Institute study found prevailing wage determinations increased the cost of federal construction by nearly 10%. On top of that, contractors pay an average of 22% above market wage rates, and in highway construction the sampled Davis-Bacon wages ran 34% higher than the average wages reported by the Bureau of Labor Statistics.

Those figures alone should raise eyebrows. Yet they only capture the visible layer of cost. The Congressional Budget Office identified three separate ways the act inflates spending: higher wages, inefficient labor requirements, and reporting and paperwork burdens placed on contractors.

The Associated Builders and Contractors puts the annual burden of the newest regulations at a $21 billion cost to U.S. taxpayers.

Even that misses the biggest driver. The largest hidden cost never appears in a compliance report. It appears in the markup.

The Fixed-Price Contract That Cannot Actually Be Fixed

Government agencies love fixed-price contracts. On paper, they transfer risk to the contractor and protect the taxpayer.

But that is not how it works in real life once Davis-Bacon enters the picture.

Under the act, the general contractor guarantees that every single person on the project receives the government-set prevailing wage. That guarantee extends down the entire chain. As the prime, you remain financially responsible for your subcontractors’ compliance even when they cut their own checks. That is a documented trap that forces general contractors to build heavy contingencies into every federal bid.

Think about what that means in practice. You are signing a fixed price while carrying unlimited exposure to the payroll behavior of companies you do not control.

The wage determination arrives attached to the contract specifications and cannot be negotiated afterward. Contractors who bid at their standard labor rates routinely discover they are underwater once prevailing wages and qualifying fringe costs kick in.

Any experienced estimator responds to that risk the only rational way: by pricing it in.

Where the Extra 20% Comes From

This is the part the official studies never capture, because it never shows up as a labor cost line. It shows up as margin, contingency, and overhead. From hands-on experience pricing complex projects, here is where the hidden money sits:

• Compliance contingency. You budget for the possibility that a subcontractor misclassifies a worker and you pick up the bill. The Department of Labor estimated compliance costs at $100 million back in 1982, alongside hundreds of millions more in inflated wage and helper-restriction costs. Those figures have only grown.

• Classification tracking. Worker classification depends on the type of work performed on the jobsite, hour by hour. The same worker can fall under different rate tables in a single day. Tracking that requires specialized software, consultants, and administrative staff. Smaller contractors pass every penny of it into the bid.

• Delay risk. Extra paperwork and compliance reviews bog projects down and lead to unanticipated, costly delays. Delays on a commercial roof mean scaffolding rental, crane hire, and site facilities all running longer. You price that in too.

• Reduced competition. Quality contractors who cannot stomach the administrative load walk away from federal work entirely. Fewer bidders means higher prices. Every estimator knows this.

Stack a compliance contingency, an administrative overhead uplift, and a risk-adjusted margin on top of wages that already run 22% to 34% above market, and the 10% government estimate collapses. The real premium on federal construction lands at 30% or more. I have watched this exact dynamic play out in commercial roofing bids, and the logic transfers directly.

The Invisible Work Is Where Money Gets Wasted or Saved

In my own trade, I refuse to compromise on the parts of a roof nobody sees. Weatherseals, air seals, and fixings determine whether a system performs as designed or fails prematurely. The invisible detail decides the outcome.

Federal construction pricing works the same way. The visible cost is the wage rate printed in the determination. The invisible cost is the risk architecture the contractor builds around it. Government estimators measure the first and ignore the second. That is why the official numbers understate reality by a factor of three.

There is a deeper industry problem underneath this. Construction has too many people trained to curate tender packages and too few who understand how the work actually gets installed. The people writing wage determinations and cost estimates have rarely stood on a roof or run a payroll for a mixed crew across four classifications in one day. The people who have done both can see the gap immediately.

The CHIPS program made this visible at national scale. The director of the CHIPS Program Office publicly noted how Davis-Bacon affected the program. One analysis put it bluntly: the act delivers little to workers, plenty to lawyers and consultants, and a bill to taxpayers for both.

Who Actually Loses Under This System

The frustrating part is that the losers are the people the act claims to protect.

Skilled installers gain little from prevailing wages when the compliance machinery around them consumes the budget. The consultants and administrators capture the difference. Meanwhile, high-quality contractors who price honestly lose federal work to operators who cut invisible corners, because the paperwork checks forms rather than fixings.

I saw a version of this early in my career. A large roofing company botched a material order, told me to do my best with what arrived, and then let me carry the blame when the install failed. Systems that reward paperwork over workmanship produce exactly that culture. Davis-Bacon compliance is paperwork over workmanship, formalized into federal law.

You, the taxpayer, fund all of it. You pay the inflated wage rate, then you pay the contingency the contractor added to survive the wage rate, then you pay the consultants who verify the wage rate was paid.

What Honest Accounting Would Look Like

I am not arguing against fair pay. I built my company on the belief that skilled trades deserve respect and proper wages. My argument is about honest measurement.

If policymakers want a true picture of what Davis-Bacon costs, they need to measure three things the current estimates skip:

• The risk premium general contractors add for subcontractor compliance liability.

• The administrative overhead of hour-by-hour classification tracking across an entire project.

• The competition effect of qualified contractors declining federal work altogether.

Measure those honestly and the 10% figure becomes indefensible. The premium sits at 30% minimum, and on complex projects it climbs higher.

The people who understand this best are the ones who have installed the work and priced the work. Their voices belong in this debate. Until they are heard, taxpayers will keep funding a gap between the official estimate and the real bill, and that gap is measured in billions every single year.

The roof analogy holds one last time. A system fails at the details nobody inspected. Federal construction costing is failing at exactly those details right now, and the invoice lands on you.
