Why Government Construction Projects Cost More
A public bid comes in higher than a private one for the same square footage because the solicitation asked for things the private job never asked for, and every one of them has a price. Bonds. A wage floor set by statute rather than by the market. Two named full-time positions, quality control and site safety, neither of which installs anything. Then a documentation load running from preconstruction submittals through closeout. None of that is contractor margin. It is scope, written by the owner, and a bid that comes in under the others usually means somebody left a piece of it out.

We write this from the position of a firm that carries the whole list as standing overhead rather than assembling it per solicitation. Imperial Construction & Electric is a certified MBE and SBE contractor. We have spent more than twenty years on public work in New Jersey and the wider Northeast region, taking awards on design-build as readily as design-bid-build, Our past performance covers VA medical facilities, other federal agencies, school districts and higher education, and owners at the state, county and municipal level. What follows is what each line actually costs an owner, and how to read a bid that appears to have skipped one.
The Wage Floor Is Set by Law, Not by the Labor Market
This is the largest single driver and the one that is most often misread as inefficiency. On public work the labor rate is a legal minimum, published in advance, and it has nothing to do with what a contractor could otherwise hire for.
On federal construction, the Davis-Bacon Act applies to every contract in excess of $2,000 to which the federal government or the District of Columbia is a party for construction, alteration or repair. The minimum wages are those the Secretary of Labor determines to be prevailing for the corresponding classes of laborers and mechanics on similar work in the civil subdivision of the state where the work is performed. That is 40 U.S.C. 3142(a) and (b).
New Jersey runs its own parallel regime with two thresholds rather than one. Under N.J.S.A. 34:11-56.26(11), the Prevailing Wage Act threshold for a contract awarded by a municipality is $19,375, effective July 1, 2024, and that figure adjusts every five years against the Consumer Price Index. For every other public body, including counties, boards of education and utility authorities, the threshold is $2,000 and does not adjust. The practical consequence for a buyer is that a county or school district job is almost always covered, while a small municipal job may sit below the line, and the same scope can therefore carry two different labor costs depending on who is awarding it.
Two things follow for an owner comparing bids. First, prevailing wage is not negotiable downward, so a bidder who is materially under the others on labor is either carrying a different classification mix or has not priced the determination correctly. Second, the wage floor comes with certified payroll, which is an administrative cost in its own right and lands in the next section.
Bonds Are a Cost, but Capacity Is the Real Constraint
Under the Miller Act, 40 U.S.C. 3131(b), before any contract of more than $100,000 is awarded for construction, alteration or repair of a public building or public work of the federal government, the contractor must furnish a performance bond in an amount the contracting officer considers adequate and a payment bond that, as a rule, equals the total amount payable under the contract and is never less than the performance bond.
The premium itself is a line item and a predictable one. The part that decides who can actually hold your award is capacity, and it is not visible on a bid form. A surety underwrites the contractor the way a lender underwrites a borrower, which means a bidder can sit comfortably inside its single-project limit on your job and still be unable to bond it because its aggregate limit is consumed by work already in progress.
Our own program is approved at $30 million on any one project, with a $125 million ceiling on uncompleted bonded backlog. It is carried by IAT Insurance Group together with its subsidiary, Harco National Insurance Company. The number worth confirming before award is available capacity, meaning the aggregate limit less bonded backlog in progress, and the confirmable version of that is a dated letter from the surety rather than a figure in a bid narrative. We go through how a procurement team should read those limits in our piece on surety bonding and public work capacity.
Two Full-Time People Who Never Install Anything
On a private job, quality control is the superintendent's job among several, and safety is a policy. On federal and most state work, both are staffed positions held by named individuals who produce no installed work.
A Construction Quality Control Manager runs the quality program and signs the daily report. A Site Safety and Health Officer runs the safety program on the ground. Both appear in the proposal by name, both are approved by the owner, and substituting either after award without notice is a compliance problem rather than a staffing preference. Imperial staffs projects with dedicated CQCMs and SSHOs, and holds Army Corps of Engineers certifications across multiple team members. You can see how the organization is built on our about us page.
Read as a cost line, that is two salaries inside a project's general conditions that a private bid for the same building simply does not carry. Read as a thing the owner is buying, it is the difference between a quality program with an owner of record and a quality program nobody is specifically accountable for. The owner chose it when they wrote the solicitation.
The Paperwork Is a Deliverable, and It Is Priced Like One
Submittals, requests for information, certified payrolls, daily quality control reports, schedule updates, as-builts, closeout documentation and performance evaluation. On public work this is a contract deliverable with its own labor behind it, not administrative friction around the real job.
Owners consistently under-estimate this line because it is invisible in the finished building. It is not invisible in the price. We have written up what the documentation package actually consists of and who inside a firm produces it in federal construction documentation as a deliverable, so we will not repeat it here. The point for a cost comparison is narrower: if one bid is appreciably lower and the schedule of values shows thin general conditions, this is usually where the money came out, and the owner finds out during performance rather than at bid opening.
Being Allowed to Bid at All Carries a Standing Cost
Before any of the above, a public bidder has to be eligible, and eligibility is maintained continuously rather than assembled for one solicitation.
Imperial holds active Public Works Contractor Registration with the State of New Jersey, contractor prequalification with the New Jersey Schools Development Authority, a Notice of Classification with the Division of Property Management and Construction, and MBE and SBE certification in New Jersey. Each of those has a renewal cycle, a reporting obligation and staff time behind it. A firm that lets any one of them lapse is not a lower-cost bidder, it is an ineligible one, and the owner finds that out at the worst possible moment.
One scope note that matters for cost comparisons. We hold a New Jersey electrical contractor's license and self-perform that trade with our own crews, inside New Jersey and nowhere else. Self-performing a major trade takes a subcontractor's markup out of that scope, which is a genuine cost difference. It is also geographically bounded, and we would rather state the boundary than let an owner outside New Jersey price a bid on it.
How to Read a Bid That Looks Too Good
The useful question is not which bid is cheapest. It is which bid priced the whole scope.
- Compare general conditions line by line rather than comparing bottom lines. CQC and safety staffing live there.
- Ask for the surety's dated letter stating available capacity, not stated capacity.
- Check the wage determination each bidder priced against, and the classifications they assigned.
- Confirm registration, prequalification and classification status are current as of the bid date, not as of last year.
- Treat an outlier low bid as a question about scope coverage rather than a discount.
A public project costs more than a private one because the public owner bought more. The number worth managing is not the premium over a private benchmark, it is whether the premium bought the compliance the project actually requires.
