- Fully loaded labor cost for a grubbing crew runs 1.40 to 1.65x base wages when workers' compensation premiums, payroll taxes, and benefits are included; workers' comp premiums for stump removal and root clearing classifications average 12-22% of wages
- The U.S. site preparation contracting sector (NAICS 238910) spans approximately 48,000 establishments with grubbing contractors representing a specialized subset competing for equipment operators alongside excavation, grading, and land clearing firms
- AGC reported in early 2026 that 66% of construction specialty contractors had open positions they could not fill, with equipment operators among the most persistent shortages in site preparation trades
- Replacing an experienced grubbing equipment operator or site foreman costs an estimated 40-65% of annual salary once recruiting, safety onboarding, and the productivity ramp-up period are counted
Grubbing industry staffing costs 2026: the full picture
Grubbing is the work that happens between tree removal and foundation work. Once a clearing crew drops trees, the grubbing phase begins: pulling stumps, severing root mats, grinding out buried root balls, and leaving a surface that grading and excavation equipment can actually work on. Without a well-run grubbing operation, every downstream trade on a site is slowed. That schedule dependency puts grubbing contractors under constant pressure while employing workers who run high-cycle equipment in conditions with real injury exposure: flying debris from stump grinders, shifting ground from unseen root systems, heavy equipment in close quarters with uneven footing.
Workers' compensation rates in grubbing and related site preparation work reflect that exposure. So does the cost of finding and keeping operators who know how to run a stump grinder in a tight residential lot, clear root mats from a waterlogged site without burying a machine, or read soil conditions well enough to avoid equipment damage on rocky terrain.
This article draws on verified 2026 data from the Bureau of Labor Statistics, the Associated General Contractors of America, CPWR (the Center for Construction Research and Training), the National Council on Compensation Insurance, the U.S. Census Bureau, and construction industry workforce surveys to give grubbing contractors and staffing decision-makers a reliable cost baseline.
1. The workforce behind the numbers
Grubbing contractors operate primarily under NAICS 238910 (Site Preparation Contractors), which the Census Bureau defines to include contractors whose specialty is preparing a site for construction through clearing, grubbing, grading, excavation, and related work. BLS Quarterly Census of Employment and Wages data shows the site preparation contracting sector employs approximately 120,000 to 160,000 workers across roughly 48,000 establishments [1][2]. Grubbing-focused contractors make up a specialized subset of that population, often working as subcontractors to larger site development and general contracting firms.
A grubbing crew typically consists of a lead equipment operator running the primary machine (excavator with grapple or thumb, rubber-tired skid steer with stump attachment, or dedicated walk-behind stump grinder for smaller residential work), one or two ground crew laborers handling root debris cleanup and equipment staging, a truck driver hauling stump and root material to disposal sites, and a foreman or working supervisor coordinating production and safety compliance.
Three cost pressures stand out for 2026.
- Residential and commercial development activity remains elevated compared to pre-pandemic baselines. New housing starts, solar facility construction, and utility infrastructure all generate grubbing demand well ahead of the foundation phase. That demand competes directly with excavation, grading, and land clearing contractors for the same pool of equipment operators.
- The equipment operator workforce is aging. CPWR data from 2024 shows that 25-30% of heavy equipment operators in construction-adjacent trades are within ten years of retirement age [3]. Grubbing has no formal apprenticeship pipeline at scale; most operators learn on the job alongside experienced crew members.
- Stump grinding and grubbing equipment has grown more sophisticated. GPS-equipped machines, remote-controlled stump grinders, and vacuum excavation units require operators with higher baseline mechanical aptitude than older equipment demanded. That raises the wage needed to retain qualified operators.
2. Wages by role: 2026 national averages
BLS Occupational Employment and Wage Statistics (OEWS) data, collected May 2024 and released March 2025, provides the most reliable national wage baseline for grubbing-related roles. Workers in grubbing operations fall primarily under the occupational classifications below. No single BLS SOC code covers "grubbing worker" specifically; the relevant categories are determined by the type of work being performed.
| Role | Mean Hourly Wage | Mean Annual Wage | BLS SOC Code |
|---|---|---|---|
| Operating Engineer / Heavy Equipment Operator | $34.82 | $72,430 | 47-2073 |
| Construction Laborer (Ground Crew / Debris Removal) | $23.47 | $48,820 | 47-2061 |
| Tree Trimmer and Pruner (Stump Crew Assist) | $22.92 | $47,670 | 37-3013 |
| First-Line Supervisor, Construction Trades (Foreman) | $39.05 | $81,230 | 47-1011 |
| Equipment Mechanic / Technician | $28.74 | $59,780 | 49-3042 |
| Heavy Truck Driver (Debris Hauling) | $25.73 | $53,520 | 53-3032 |
| Construction Estimator | $36.41 | $75,730 | 13-1051 |
| Office Administrator / Dispatcher | $21.26 | $44,220 | 43-1011 |
Source: BLS Occupational Employment and Wage Statistics, May 2024 (released March 2025) [4].
The median wage for operating engineers nationally sits at $30.12/hour ($62,640/year), while the mean is pulled higher by experienced operators on commercial and public projects, where prevailing wage requirements and union scale apply. A grubbing equipment operator on a federally funded infrastructure project in a high-wage metro can earn $40-$50/hour under applicable prevailing-wage determinations.
Ground crew laborers handling stump debris, root fragment disposal, and clean-up around the machine occupy the lower end of the wage range. On residential grubbing projects, it is common to see laborers earning $18-$22/hour in lower-cost regions and $26-$32/hour in California, New York, and the Pacific Northwest. Those regional variations track closely with construction laborer wages generally, since the BLS construction laborer classification (47-2061) captures this role regardless of whether the laborer is on a grubbing site, a concrete pour, or a trenching operation.
Foremen and working supervisors at grubbing contractors earn substantially more than lead operator wages in markets where experienced site supervisors are scarce. A foreman who can manage a grubbing crew, read site plans, coordinate with land clearing and grading subcontractors, and handle client communication on a development site consistently earns $75,000-$90,000 in annual base wages in most U.S. regions, and $95,000-$110,000 in high-cost coastal markets.
3. Workers' compensation rates: the cost layer base wages do not show
Grubbing is one of the higher-risk activities in site preparation work. NCCI (National Council on Compensation Insurance) classification data and state rating bureau schedules put workers' compensation base rates for grubbing-adjacent work in ranges that significantly increase employer labor costs above base wage.
| Work type / NCCI classification | Typical base rate range (% of wages) |
|---|---|
| Stump removal and grubbing (heavy equipment-based) | 8-18% |
| Stump grinding (walk-behind, residential scale) | 10-22% |
| Land clearing / site preparation (NOC) | 12-24% |
| Ground crew labor on clearing and grubbing sites | 12-20% |
| Construction laborer (general site prep) | 8-14% |
Sources: NCCI Scopes of Basic Manual Classifications; state rating bureau schedules [5].
Workers' comp rates vary by state, employer experience modification factor (EMR), payroll volume, and the specific classification code assigned by the insurer. New contractors without a claims history typically pay at or above the state bureau rate for their assigned class. Contractors with an EMR below 1.0 from a clean claims record can pay materially less. Contractors with a history of soft-tissue injuries, struck-by incidents, or equipment damage claims can see their effective rate climb well above the bureau base.
For a grubbing equipment operator earning $72,430/year, an employer at a 15% effective workers' comp rate is paying an additional $10,865 per year in WC premiums alone before FICA, FUTA, SUTA, or health benefits are added. That single cost layer adds roughly $5.22/hour to the actual cost of that operator, pushing the fully loaded hourly labor cost from $34.82 to approximately $40/hour before anything else is counted.
4. Fully loaded labor cost: what an operator actually costs
Base wages are what shows up in job posts. What a grubbing contractor actually spends per employee per year runs considerably higher. The table below builds up a representative fully loaded cost for an operating engineer on a grubbing crew using the national mean wage and standard employer overhead rates for 2026.
Fully loaded cost estimate: operating engineer (national mean)
| Cost component | Annual cost |
|---|---|
| Base wage (BLS mean, 47-2073) | $72,430 |
| FICA - Social Security (6.2% to $176,100 cap) | $4,491 |
| FICA - Medicare (1.45%, no cap) | $1,050 |
| Federal Unemployment Tax (FUTA, effective ~0.6%) | $42 |
| State Unemployment Tax (SUTA, est. 2.0% on $7K-$14K wage base) | $250 |
| Workers' compensation (est. 15% of wages) | $10,865 |
| Health insurance contribution (employer share, est.) | $7,500 |
| Other benefits (retirement contribution, paid leave, est.) | $4,000 |
| Total fully loaded employer cost | ~$100,628 |
| Effective hourly cost (2,080 hours) | ~$48.38/hour |
The 1.40-1.65x multiplier range cited in the key takeaways reflects this arithmetic. An operator earning $34.82/hour in base wages costs the employer approximately $48-$57/hour depending on benefits package, workers' comp experience modification, and state tax rates. For labor-intensive grubbing contractors where the crew is the primary cost center, this gap between bid-rate wages and actual labor cost is where job costing errors most frequently occur.
5. The workforce shortage driving wages higher
The AGC's 2026 workforce survey found that 66% of specialty contractors reported having open positions they could not fill [6]. Equipment operators and skilled laborers are consistently among the hardest roles to fill in site preparation trades. For grubbing contractors specifically, the shortage has a few compounding characteristics.
- Grubbing is not glamorous work. It involves hours of grinding, pulling, and loading stumps in mud, on uneven terrain, in summer heat or winter cold. Recruiting people into this work from outside the trades is difficult.
- Most experienced grubbing operators came up through land clearing, logging, excavation, or landscaping and transitioned into grubbing work over time. There is no direct training pipeline producing grubbing-ready operators.
- The equipment base has diversified. Beyond traditional track excavators and bulldozers, modern grubbing operations use vacuum excavators for utility-proximity work, remote-controlled stump grinders for slope and confined space applications, and forestry mulchers for brush and fine-root clearing. Operators who can run multiple machine types are in shorter supply and know it.
- The job market for equipment operators is transparent. Someone running a stump grinder for a grubbing contractor can see competing job posts from excavation contractors, highway contractors, and utility companies in the same metro and judge whether the wages are worth the specific physical demands of grubbing work. That keeps upward pressure on wages.
BLS projects approximately 29,900 job openings per year for operating engineers and other construction equipment operators through 2033, driven predominantly by workforce attrition rather than expansion [4]. The sector is not adding large numbers of new operator positions. It is struggling to replace workers who are retiring or moving into less physically demanding roles.
6. Seasonal and project-cycle patterns in staffing costs
Grubbing work is closely tied to construction starts. In most U.S. markets, grubbing activity tracks with the broader construction season: heaviest from March through November, with pullback in December through February in northern climates. That seasonality creates real labor cost management challenges.
Contractors who maintain year-round employment retain experienced operators through the slow season by offering consistent pay and health benefits. Operators who can find year-round work elsewhere will take it. Contractors who accept turnover at season's end pay to rehire and retrain when the next season opens.
The cost of a vacant operator slot during peak production season (typically late spring and summer, when residential development and infrastructure grubbing demand peak simultaneously) goes beyond the missed billable hours. It can push a grubbing contractor to rent equipment and hire short-term through a staffing agency at premium rates, or to turn down subcontract work that could not be adequately staffed.
Staffing agencies that place construction equipment operators typically charge a markup of 50-75% over direct pay rates. An operator earning $30/hour direct costs a contractor approximately $45-$52/hour through agency placement when the agency markup, employer-of-record payroll taxes, and workers' compensation coverage are combined. For a contractor filling a peak-season gap with two agency-placed operators for six weeks, that premium adds $25,000-$40,000 in unplanned labor cost above what direct employment would have cost for the same period.
7. Regional wage variation
Grubbing wages track regional construction labor markets closely. High-cost metros and states with strong union density or high prevailing-wage project volumes show materially higher wages than rural or southern markets.
| Region | Operating Engineer Avg. Hourly | Construction Laborer Avg. Hourly | Notes |
|---|---|---|---|
| National mean | $34.82 | $23.47 | BLS OEWS May 2024 |
| California | $45-$56 | $30-$38 | High prevailing-wage project mix, union density |
| New York / Northeast | $42-$54 | $28-$36 | NYC metro pushes regional average up |
| Pacific Northwest | $38-$48 | $26-$33 | Strong utility and infrastructure pipeline |
| Texas / Southeast | $26-$34 | $17-$22 | Lower union density, competitive non-union market |
| Midwest (IL, OH, MI) | $30-$40 | $20-$26 | Higher in Chicago metro, lower in rural markets |
| Mountain West | $30-$40 | $20-$28 | Growing demand from solar and infrastructure work |
Sources: BLS OEWS May 2024 state-level data; Davis-Bacon prevailing wage determinations [4][7].
On federally funded infrastructure projects subject to Davis-Bacon Act prevailing wage requirements, grubbing contractors must pay local prevailing wages determined by the DOL Wage and Hour Division. Those wages in most urban markets are set at or above union scale and can run $55-$75/hour for operating engineers in high-cost metros when fringe benefit contributions are included. Grubbing work on highway, airport, or transit construction projects in those markets carries labor costs that are structurally different from private commercial or residential grubbing subcontracts.
8. Turnover costs and workforce retention
Turnover is expensive in any field labor operation, and grubbing work carries specific turnover cost drivers.
An experienced grubbing equipment operator is not a commodity hire. A productive grubbing operator reads soil conditions, adapts machine approach based on root system density, works efficiently around buried utilities, and keeps high-cycle equipment running through daily maintenance. That knowledge builds over months and years. When an experienced operator leaves, a replacement typically takes six to twelve months to reach comparable production efficiency.
Turnover cost estimates from construction workforce research consistently land in the range of 40-75% of annual salary for skilled equipment operators when recruiting, onboarding, training time, and the productivity gap during the ramp-up period are combined [3][8]. For a grubbing contractor losing an operator earning $72,430/year, that translates to a turnover cost of approximately $29,000-$54,000 per departure event.
Three things drive turnover in grubbing specifically.
First, the physical demands. Grubbing is hard on the body: vibration from grinding cycles, long hours in a cab, and the cleanup work for operators who also assist with debris removal all accumulate. Physical fatigue pushes people toward easier roles over time.
Second, wage competition. Operators who develop equipment skills in grubbing can move laterally to excavation, highway, utility, and other construction equipment operator roles without much friction. The job market for qualified operators is broad and visible to anyone with a smartphone.
Third, benefits gaps. Smaller grubbing contractors with tight margins often offer limited health and retirement benefits compared to larger general contractors or union signatory employers. That gap is most damaging for operators in their mid-30s to early 50s, who are paying close attention to what their coverage and retirement contributions actually look like.
9. Benefits overhead and total compensation
Benefits are a real share of total labor cost in the construction trades. BLS Employer Costs for Employee Compensation (ECEC) data for Q4 2025 shows that benefits accounted for 29.6% of total compensation for private-sector workers, with health insurance representing 7.4% and paid leave 7.6% [9].
For grubbing contractors, benefits overhead splits between what is legally required and what is needed to remain competitive in the operator labor market.
Legally required benefits
| Benefit | Approximate employer cost |
|---|---|
| FICA (SS + Medicare) | 7.65% of wages |
| FUTA | 0.6% on first $7,000 |
| SUTA | 1.5-4.0% (varies by state and claims history) |
| Workers' compensation | 12-22% of wages (classification-dependent) |
Market-competitive benefits for retention
| Benefit | Common structure |
|---|---|
| Health insurance | Employer contributes $400-$800/month per employee |
| Retirement / 401(k) | 3-5% employer match, increasingly expected |
| Paid time off | 5-15 days/year typical for non-union |
| Tool and PPE allowance | $500-$1,500/year for operators with personal tool requirements |
| Per diem (travel work) | $75-$125/day when crew is working away from home base |
For grubbing operators earning the national mean of $72,430/year, a contractor providing a full benefits package typical of a mid-size site preparation firm spends approximately $20,000-$28,000 per operator per year in benefits and payroll tax overhead. Combined with base wages, total compensation per operator runs approximately $92,000-$100,000 annually.
10. Administrative and compliance overhead
Grubbing contractors running four or more employees carry administrative overhead that is easy to undercount in a job-cost model.
OSHA regulations applicable to grubbing and stump removal work include 29 CFR Part 1926 Subpart O (Motor Vehicles and Mechanized Equipment), Subpart P (Excavations, when root removal involves soil disturbance to required depths), and general duty clause obligations around struck-by and caught-between hazards from grinding operations. Maintaining OSHA compliance on grubbing projects requires documented safety training, equipment inspection records, PPE provisioning, and toolbox talk documentation that adds real administrative hours per week.
State contractor licensing requirements vary. Many states require site preparation contractors to carry a licensed contractor registration, separate from trade licenses. Keeping those registrations current, tracking insurance certificate renewals, and managing subcontractor compliance documentation on larger jobs falls on administrative staff or the contractor's principals if no dedicated admin is in place.
Payroll processing, prevailing-wage certified payroll reporting (on applicable public projects), lien waiver management, equipment maintenance scheduling, and subcontract management round out the administrative workload. A grubbing contractor running a crew of five to eight with no dedicated office staff typically sees the owner or a site supervisor spending 8-15 hours per week on non-billable administrative tasks.
Certified payroll preparation, equipment maintenance logs, permit tracking, subcontract correspondence, and calendar management do not require a physical presence on the job site. A virtual assistant can handle that workload at a fraction of what a full-time office hire costs, which is why remote administrative support has become more common in site preparation as administrative complexity has grown faster than most working owners can absorb.
11. Comparing grubbing staffing costs to related site preparation trades
Grubbing sits within a family of site preparation trades that share similar labor pools and cost structures. The table below shows where it falls relative to adjacent work.
| Trade | Lead operator mean wage | Workers' comp rate range | Notes |
|---|---|---|---|
| Grubbing / stump removal | $72,430/yr ($34.82/hr) | 12-22% | High WC due to grinding debris exposure |
| Land clearing | $72,430/yr ($34.82/hr) | 12-24% | Overlapping operator pool, higher risk on ROW work |
| Excavation | $72,430/yr ($34.82/hr) | 8-16% | Lower WC typical on trench excavation vs. clearing/grinding |
| Grading | $72,430/yr ($34.82/hr) | 8-14% | Less debris exposure than clearing/grubbing |
| Demolition | $72,430/yr ($34.82/hr) | 18-32% | Higher WC due to structural collapse and hazmat exposure |
Source: BLS OEWS May 2024; NCCI classification schedules [4][5].
All of these trades pull from the same operating engineer labor pool. The difference in workers' compensation rates reflects the distinct hazard exposure of each trade. Grubbing sits in the middle - higher than grading and excavation because of the grinding debris and root-system unpredictability, lower than demolition because grubbing does not involve structural collapse risk or regulated hazardous materials.

12. Key cost benchmarks for grubbing contractors in 2026
For grubbing contractors and site development decision-makers building labor budgets, these are the verified benchmarks as of mid-2026.
| Benchmark | Figure | Source |
|---|---|---|
| Operating engineer mean wage (national) | $72,430/yr ($34.82/hr) | BLS OEWS May 2024 [4] |
| Construction laborer mean wage (national) | $48,820/yr ($23.47/hr) | BLS OEWS May 2024 [4] |
| First-line supervisor mean wage (construction) | $81,230/yr ($39.05/hr) | BLS OEWS May 2024 [4] |
| Workers' comp rate (grubbing/stump removal) | 12-22% of wages | NCCI schedules [5] |
| Fully loaded operator cost (multiplier) | 1.40-1.65x base wage | Calculated from above overhead layers |
| Turnover cost per experienced operator | 40-65% of annual salary | CPWR workforce research [3][8] |
| Agency markup for temp equipment operators | 50-75% above direct pay rate | Industry staffing data |
| Specialty contractor vacancy rate (2026) | 66% have unfilled positions | AGC workforce survey [6] |
| Annual equipment operator job openings (national) | ~29,900 per year through 2033 | BLS OOH [4] |
Base wage accounts for roughly 60-70% of actual labor cost in grubbing operations. Workers' compensation, payroll taxes, and benefits cover the remaining 30-40%. Job costing that skips these layers will consistently underprice labor-intensive work.
For grubbing contractors dealing with administrative overhead that grows with crew size, a discovery call can clarify which compliance, scheduling, and documentation tasks can be handled by remote support staff.

Frequently Asked Questions
What are the average grubbing industry staffing costs in 2026?
Equipment operators on grubbing projects earn a national mean of $72,430 per year ($34.82/hour) per BLS OEWS data from May 2024. Ground crew laborers average $48,820/year ($23.47/hour). Once workers' compensation premiums (12-22% of wages), payroll taxes, and benefits are included, the fully loaded cost per operator runs approximately $48-$57/hour, or 1.40-1.65x the base wage rate.
How do grubbing industry labor costs compare to similar site preparation trades?
Grubbing sits in the middle of the site preparation cost range. Base equipment operator wages are comparable to excavation, grading, and land clearing at around $72,430/year. Workers' compensation rates for grubbing (12-22%) are higher than grading and basic excavation (8-16%) because stump grinding and root removal expose workers to flying debris, equipment rollover on uneven terrain, and struck-by hazards. Demolition carries the highest WC rates (18-32%) in the broader construction family.
How can grubbing contractors reduce staffing costs without losing quality?
Many grubbing contractors control costs by outsourcing administrative overhead - certified payroll, permit tracking, equipment maintenance scheduling, and office coordination - to remote support staff rather than adding in-house headcount. A virtual assistant handling those tasks costs a fraction of a full-time office employee and frees up field supervisors to stay on operations. See also our research on land clearing industry staffing costs 2026 for context on adjacent trade cost structures.
