A mid-size general contractor in Denver ran the numbers in January 2026 and did not like what they found. Over the previous twelve months, 127 of their 340 field employees had left — a 37.4% turnover rate. When they calculated the fully loaded cost of replacing each departed worker — recruiting, onboarding, training, lost productivity during the ramp-up period, and the downstream effects on crew efficiency — the total came to $596,900.
That is $4,700 per departed worker. And that Denver contractor is not an outlier.
The Associated General Contractors of America's 2026 Workforce Survey, conducted in partnership with Autodesk, found that the median annual turnover rate for construction field workers is 38.2%, and the median fully loaded replacement cost is $4,700 per worker. For skilled trade workers — electricians, plumbers, pipefitters, ironworkers — the replacement cost is significantly higher, averaging $6,800.
Construction has the second-highest turnover rate of any major industry in the United States, behind only hospitality. And unlike hospitality, where positions can be staffed and trained in days, construction workers require months to become fully productive and years to become truly skilled.
This article quantifies the real cost of construction turnover, identifies the primary drivers, and outlines the retention strategies that are actually working in 2026.
Breaking Down the $4,700
The $4,700 average replacement cost is not a guess. It is a calculated sum of direct and indirect costs that most contractors track poorly or not at all. Here is the breakdown, based on the AGC survey data, CPWR research, and our own analysis of contractor-reported costs:
Direct costs: $1,850 per worker
Recruiting and hiring: $620
- Job board postings: $150-$300 per listing (Indeed, ZipRecruiter, trade-specific boards)
- Recruiter time: approximately 12 hours at $35/hour fully loaded = $420 for screening, interviewing, and onboarding paperwork
- Background checks and drug testing: $75-$150
Onboarding and orientation: $480
- Safety orientation: 4-8 hours of new-hire time at $32/hour average = $128-$256
- Orientation facilitator time: 4-8 hours at $45/hour = $180-$360
- PPE issuance: $150-$300 (hard hat, vest, safety glasses, gloves, boots if provided)
- Payroll and benefits enrollment: 2-3 hours of administrative time = $80-$120
Training and certification: $750
- OSHA 10-hour training (if not already certified): $200-$400 including time and materials
- Site-specific training: 4-8 hours = $128-$256
- Trade-specific training and equipment familiarization: varies, average $200-$400
- Certifications (forklift, aerial lift, confined space) if required: $150-$400
Indirect costs: $2,850 per worker
This is where most contractors lose track, because indirect costs are real but harder to measure.
Lost productivity during ramp-up: $1,600
A new construction worker — even an experienced one — does not reach full productivity on a new jobsite immediately. They need to learn the site layout, the crew's communication patterns, the superintendent's expectations, the project-specific specifications, and the physical flow of materials and personnel.
Research by the Construction Industry Institute found that new hires on construction projects operate at approximately 60% productivity in their first two weeks, 75% in weeks three through four, and 90% in weeks five through eight. Full productivity is typically reached at six to eight weeks for experienced workers and twelve or more weeks for less experienced ones.
For a worker earning $32/hour, the productivity gap over the first eight weeks looks like this:
- Weeks 1-2: 40% productivity loss × 80 hours = 32 hours × $32 = $1,024
- Weeks 3-4: 25% productivity loss × 80 hours = 20 hours × $32 = $640
- Weeks 5-8: 10% productivity loss × 160 hours = 16 hours × $32 = $512
- Total ramp-up cost: $2,176
We use $1,600 as a conservative estimate that accounts for the fact that not all departing workers are replaced with equally experienced new hires.
Crew disruption: $800
When a worker leaves, the remaining crew absorbs the workload until a replacement is hired and ramped up. This means overtime, reassigned tasks, and disrupted crew dynamics. A four-person crew that loses one member does not operate at 75% efficiency — it operates at roughly 65-70% because the remaining workers are covering unfamiliar tasks, adjusting work sequences, and losing the coordination efficiencies that come from working together over time.
The foreman or superintendent also spends time managing the disruption — adjusting schedules, redistributing work, and dealing with the morale effects of turnover.
Administrative costs: $450
Exit processing, final paychecks, COBRA notifications, equipment return, access badge deactivation, insurance adjustments, and the paperwork of hiring a replacement. None of these tasks are individually expensive, but they add up to approximately 10-15 hours of administrative time per turnover event.
The skilled trades premium
For skilled trade workers, the costs are amplified:
Electricians, plumbers, pipefitters: Average replacement cost of $6,800
- Higher recruiting costs (skilled trade workers are in extreme demand)
- Longer ramp-up periods (trade-specific knowledge of the project's systems)
- Greater crew disruption (more specialized tasks that cannot be easily absorbed by others)
- Certification and licensing verification
Superintendents and project managers: Average replacement cost of $12,400
- Executive recruiting fees ($3,000-$8,000)
- Extended ramp-up period (3-6 months to full project knowledge)
- Relationship capital loss (subcontractor relationships, owner relationships, AHJ relationships)
Safety note: Turnover is a safety issue, not just a cost issue. CPWR data shows that workers in their first year with a new employer have a recordable injury rate 2.1 times higher than workers with two or more years of tenure. Every time you replace a worker, you are statistically increasing the probability of a safety incident on your project. The OSHA citation data consistently shows that inexperience and inadequate training are root causes of violations — and turnover is the mechanism that keeps putting inexperienced workers on your jobsite.
What the Total Looks Like
For a contractor with 200 field employees and a 38% annual turnover rate:
- Workers departing per year: 76
- Average replacement cost per worker: $4,700
- Annual turnover cost: $357,200
For a contractor with 500 field employees:
- Workers departing per year: 190
- Annual turnover cost: $893,000
For a contractor with 1,000 field employees:
- Workers departing per year: 380
- Annual turnover cost: $1,786,000
These are not small numbers. They are the equivalent of a significant construction project's profit margin. A contractor operating on 5% net margins would need $7.1 million in additional revenue just to cover the turnover cost of a 200-person workforce.
Why Workers Leave
The AGC 2026 Workforce Survey asked contractors to identify the top reasons for voluntary departures. The results, ranked by frequency:
1. Higher pay elsewhere (cited by 71% of respondents)
Construction workers move for money, and the tight labor market gives them leverage. When the contractor across town is paying $2/hour more, workers do not owe you loyalty — they owe their families a better paycheck.
The solution is not necessarily to be the highest-paying contractor in your market (though that helps). It is to be competitive and transparent. Workers who feel they are paid fairly relative to their skills and the market are less likely to chase marginal pay increases, especially when other factors (see below) are favorable.
2. Better working conditions (cited by 52%)
"Working conditions" is a broad category that includes safety culture, quality of supervision, work hours, commute distance, and the physical environment. Workers will accept moderate pay for excellent conditions, and they will leave high pay if conditions are poor.
The most commonly cited specific conditions include:
- Excessive overtime without adequate notice or choice
- Long commutes to remote project locations
- Poor safety practices or a culture that discourages reporting
- Abusive or disrespectful supervision
- Inadequate facilities (restrooms, break areas, parking)
3. Lack of advancement opportunity (cited by 43%)
Workers who see a path forward — from apprentice to journeyperson, from journeyperson to foreman, from foreman to superintendent — are significantly more likely to stay with their employer. Workers who feel stuck in the same role with no clear path to advancement will leave for an employer who offers one.
4. Inconsistent work (cited by 38%)
Layoffs between projects, unpredictable schedules, and seasonal downtime drive workers to employers who can offer more consistent work. Workers with mortgages and families cannot afford to be laid off for six weeks between projects.
5. Benefits and retirement (cited by 34%)
Health insurance, retirement plans, and paid time off matter. Workers who have access to quality benefits through their employer — particularly family health coverage — have turnover rates approximately 15% lower than workers without benefits, according to CPWR data.
Retention Strategies That Work
Pay transparency and regular wage reviews
Conduct market wage surveys quarterly (AGC, local contractor associations, and BLS data provide good benchmarks). Adjust wages proactively — do not wait for workers to threaten to leave. Consider posting wage scales so workers know what they can earn as they advance in skill and responsibility.
Foreman and superintendent training
The single most impactful retention investment is training your front-line supervisors to be better leaders. Research consistently shows that workers leave supervisors, not companies. A foreman who communicates clearly, treats workers with respect, enforces safety standards fairly, and advocates for their crew retains workers even when pay is not the highest in the market.
Invest in formal foreman training programs. The AGC Supervisory Training Program (STP), FMI's leadership development courses, and trade-specific programs (the NECA Management Education Institute for electrical, the MCA Management Methods for mechanical) all provide structured development for front-line supervisors.
Career pathway mapping
Show every worker where they can go. Create a visual career pathway from laborer to journeyperson to foreman to superintendent to project manager. Identify the training, certifications, and experience required at each level. Conduct annual career conversations where supervisors discuss each worker's goals and development plan.
Consistent work planning
Reduce layoff frequency by maintaining a backlog of work that provides continuous employment for your core workforce. This means:
- Bidding and winning a mix of project types and sizes that smooth out workflow
- Cross-training workers so they can be deployed across project types
- Maintaining relationships with subcontractors who can absorb your workers during gaps (with a commitment to bring them back)
Benefits that matter
Health insurance is table stakes. Beyond that, consider:
- Retirement contributions: Even modest employer contributions to a 401(k) or union pension significantly improve retention
- Paid time off: Construction workers who receive PTO report higher job satisfaction and lower intent to leave
- Mental health resources: EAP access, suicide prevention programs, and substance use support address real needs in the construction workforce
- Training and certification funding: Paying for workers to obtain additional certifications (CDL, crane operation, welding certifications) builds loyalty and capability simultaneously
Retention bonuses and loyalty programs
Some contractors have implemented retention bonuses — lump-sum payments after 12, 24, or 36 months of continuous employment. Typical amounts range from $500 to $2,500. The math is straightforward: a $1,500 annual retention bonus costs less than one-third of the $4,700 replacement cost.
Exit interviews — and acting on them
When workers leave, find out why. Not a check-the-box form — a genuine conversation with someone the departing worker trusts (not their direct supervisor). Track the reasons. Look for patterns. If three workers in six months cite the same foreman's behavior as a factor, that is actionable intelligence.
For context on how the broader construction workforce shortage is intensifying the competition for workers, and how rising wages reflect the market's response to that competition, see our related analysis.
The ROI of Retention
Consider a 300-person contractor that reduces its turnover rate from 38% to 28% — a 10-percentage-point improvement. That reduction means 30 fewer departures per year, saving approximately $141,000 annually in replacement costs.
The investments required to achieve that reduction — competitive wages, supervisor training, better benefits, retention bonuses — might cost $200,000-$300,000. But the savings compound: lower turnover means more experienced crews, which means higher productivity, fewer safety incidents, better quality, and lower rework costs. The fully loaded ROI of a 10-point turnover reduction is typically 3:1 or better within two years.
The construction industry's turnover problem is not intractable. It is an investment problem. The companies that invest in retention — systematically, consistently, and measurably — outperform the companies that treat workers as replaceable.
Frequently Asked Questions
What is the average cost of replacing a construction worker?
The fully loaded cost of replacing a construction field worker averages $4,700, according to the AGC 2026 Workforce Survey and supporting research. This includes direct costs (recruiting, onboarding, training, PPE) averaging $1,850 and indirect costs (lost productivity during ramp-up, crew disruption, administrative processing) averaging $2,850. For skilled trade workers such as electricians and plumbers, the average replacement cost rises to $6,800. For superintendents and project managers, it can exceed $12,400.
What is the turnover rate in construction?
The median annual turnover rate for construction field workers is 38.2%, according to the AGC 2026 Workforce Survey — the second-highest rate of any major U.S. industry, behind only hospitality. This means that a contractor with 200 field employees can expect approximately 76 departures per year. The rate varies by trade (laborers have higher turnover than licensed trades), by region (turnover is highest in markets with the tightest labor supply), and by company (firms with strong retention programs report rates 10-15 percentage points lower than the industry median).
Why do construction workers quit?
The top reasons construction workers leave their employers, according to the AGC 2026 Workforce Survey, are: higher pay elsewhere (71% of respondents), better working conditions at another employer (52%), lack of advancement opportunity (43%), inconsistent work and layoffs between projects (38%), and inadequate benefits and retirement (34%). Notably, pay is the most frequently cited reason, but working conditions and advancement opportunities are significant factors that employers can address without necessarily being the highest-paying contractor in their market.
How can construction companies reduce turnover?
The most effective retention strategies include: competitive and transparent pay with regular market-based wage reviews, foreman and superintendent leadership training (workers leave supervisors, not companies), clear career pathway mapping from entry-level through management, consistent work planning that minimizes layoffs between projects, quality benefits including health insurance and retirement contributions, retention bonuses for continuous employment, and genuine exit interviews that identify and address systemic issues. A 10-percentage-point reduction in turnover for a 300-person contractor saves approximately $141,000 annually in direct replacement costs, with additional savings from improved productivity and safety.
