“I Couldn’t Believe My Eyes When I Saw This Number”

March 2025. Office of ModernBuilders LLC, Phoenix, Arizona.

Mike Richardson, 55, owner of a specialty construction firm focused on highway and infrastructure projects, is reviewing the 2024 financials with his advisor.

The advisor’s finger stops on one line of the income statement:

Advisor: “Mike, see this number? $27.9 million in payroll costs.”

Mike: “Yeah, I know. We have about 60 employees - crew members, project managers, and office staff. What’s the problem?”

Advisor: “This cost alone is 49.7% of your revenue. Almost half of every dollar you bring in goes straight to payroll.”

Mike picks up his calculator. Does the math.

Revenue 2024: $56,328,510
Payroll: $27,982,160
Percentage: 49.7%

He sits silently for 10 seconds.

Mike: “Wait… You’re telling me that for every $100 we bill, $50 goes to payroll?”

Advisor: “Exactly. And the industry benchmark for highway construction is 32-35%. You’re 15 points over.”

Mike leans back in his chair.

Mike: “And what’s this… ‘overage’ costing me?”

Advisor: “If you were aligned at 35%, you’d save $8.3 million annually. With that money, you could buy 13 new excavators. Or hire 5 project engineers. Or simply… make more profit.”

Mike (after a long pause): “But I can’t just fire 20 people tomorrow. Some have worked with me for 15 years. How do I handle this?”

This is the conversation that 68% of US construction company owners should be having with someone, but never do.

Because payroll cost is the taboo of SME construction firms: everyone knows it’s too high, nobody knows how to reduce it without destroying the company (and hurting people).


The Problem Nobody Wants to Face

Construction industry data 2024: 68% of construction SMEs have labor costs >40% of revenue, 42% exceed 45% (critical threshold). Only 18% align with the 30-35% benchmark.

Consequences: Margins compressed to 5-8% (vs 12-15% optimal), inability to invest in equipment/technology, recurring cash flow crises.

The paradox: Construction companies are labor-intensive, but when payroll exceeds 45%, it becomes impossible to sustain operations during slow periods. In government contracts it’s lethal: you front 100% of costs, get paid 4-8 months later. If fixed costs are too high, cash flow dries up even on profitable projects.


The ModernBuilders Case: Anatomy of Out-of-Control Costs

The Brutal Numbers

ModernBuilders LLC - 2024 Financials:

Item Amount % of Revenue
Payroll Costs $27,982,160 49.7% 🔴
Materials & subcontractors $10,720,331 19.0%
Equipment & facilities $6,367,083 11.3%
Other operating costs $7,381,905 13.1%
EBITDA $3,877,029 6.9%
Total Revenue $56,328,510 100%

Translation: Of every $100 in revenue, $49.70 goes to payroll. Labor costs more than ALL other expenses combined.

Workforce: 58 employees (average cost $48k/year). Breakdown: 32 field workers, 13 equipment operators, 8 project staff, 3 administrative, 2 managers.


The Killer Comparison: ModernBuilders vs Industry Benchmark

| Metric | ModernBuilders | Industry Average | Top 25% | Gap | |—|—|—|—| | Labor % of revenue | 49.7% | 35.0% | 28.0% | +14.7pp 🔴 | | Revenue per employee | $97,112 | $165,000 | $220,000 | -41% 🔴 | | Average cost per employee | $48,244 | $46,200 | $44,500 | +4.4% 🟡 | | Productivity (revenue/hour) | $46 | $80 | $106 | -42% 🔴 |

Diagnosis: Cost per employee is OK (+4%), but productivity is -41%. Problem: too many employees, not employees who cost too much.


Why This Happened

In 2024 mega infrastructure projects (federal infrastructure bill, state DOT contracts) drove revenue from $19M (2023) to $56M (+192%). Mike hired 30+ employees to handle the workload.

In 2025 projects completed, revenue dropped to $46M (-18%), but headcount stayed at 58 (emotional difficulty letting people go, hope for new contracts).

Result: 58 employees instead of optimal 42 (+40% overstaffing).

Aggravating factors:


Practical Plan: Reduce from 49.7% to 38% WITHOUT Mass Layoffs

Objective:


PHASE 1: Quick Wins (0-3 months) → $835k/year

1.1 Stop Turnover Replacement + Hiring Freeze

Don’t replace resignations, don’t renew temporary contracts, prepare for retirements.

Savings: $332k/year (3 voluntary departures + 2 retirements + 2 contract expirations).


1.2 40% Overtime Reduction

A) Weekly shift planning:

B) Productivity incentives:

Savings: $420k/year


💡 The Alternative: Before Reducing Headcount, Eliminate Waste

The Plan calls for reducing from 58 to 42 employees over 18 months.

But there’s a lever to pull BEFORE touching headcount:

RECOVERING LOST HOURS AND HIDDEN WASTE

Construction companies with 50+ employees typically lose:

The problem: Paper timesheets + monthly review = you detect problems after project completion (margin already eroded).

Alternative approach:

For companies with 15+ active projects and weak job costing controls, there are AI agent systems (e.g., Mentally.ai) that connect to:

What they do:

Instead of manual data entry, the agents:

Difference vs traditional software:

Investment: $25-80K (scales with complexity)
ROI: 3-8x in 12-18 months (companies $10-50M with significant waste)

Makes sense for: ✅ Weak job costing controls (recurring overruns)
✅ 15+ projects/year, scattered data
✅ Labor >40%, need to optimize utilization
✅ Margins <10% (every percentage point matters)

Recovery is ADDITIONAL to headcount reduction.

1.3 Convert Full-Time Admin to Part-Time

ModernBuilders: 3 full-time administrative staff for $56M revenue. Benchmark: 1 per $40-50M.

Solution: 2 full-time + 1 part-time 50%. Remaining tasks: outsource to accounting firm ($550/month).

Savings: $18,900/year


1.4 Outsource Equipment Maintenance

In-house mechanic $51k/year → Service contract with shop $44,400/year. Mechanic becomes field worker (reskilling).

Net savings: $6,600/year
PLUS: Former mechanic generates +$76k revenue (ROI 11.5x)

PHASE 1 TOTAL: $835k/year
Labor percentage: 49.7% → 48.1%


PHASE 2: Reorganization (4-9 months) → $1,320k/year

2.1 Incentivized Early Retirement (3 Employees)

Target: 3 employees aged 62-64 (2-3 years from retirement). Current cost: $165,900/year.

Proposal: $37k net one-time incentive for early retirement.

How to present it:
✅ “We’re offering an incentive package so you can enjoy retirement with your family. Take your time thinking about it.”
❌ Not: “You’re old and cost too much.”

Savings: $165,900/year (from year 2). ROI: 8-month payback.


2.2 Cross-Training Field Workers

Problem: Equipment operator idle 20% of time (equipment not in use) = full cost, zero output.

Solution: Train 6 workers → Heavy equipment certifications ($1,600/person). Same worker operates equipment + works on ground.

Savings: $332k/year (6 specialized operators not hired).


2.3 Hybrid Model: Core + Flex

CORE (fixed): 42 permanent employees = $20,184k/year (36.7% revenue)
FLEX (variable): Subcontractors for peaks/specialties = $2,750k/year (5% revenue)
TOTAL: 41.7% revenue

When to subcontract: Specialized work, seasonal peaks, occasional skills.
When NOT to: Routine repetitive work.

Transition: Years 1-2 natural reduction 58→47. Year 3 stabilization at 42+subcontractors.

Savings: $822k/year net

PHASE 2 TOTAL: $1,320k/year
Labor percentage: 48.1% → 45.2%


PHASE 3: Permanent Efficiency (10-18 months) → $660k/year

3.1 Project Management Digitalization

Project management software (Procore, Buildertrend): $5,760/year (manual entry).

AI agents for data integration (Mentally.ai, similar): $25-80K investment. Auto-import from banks, accounting, email. Automatic anomaly alerts, real-time aggregation.

When to prefer agents: 15+ projects, weak controls, margins <8% (every point matters).

Benefits (traditional software):

Net savings: $479k/year (considering headcount optimization)


3.2 Crew Productivity Incentives

Baseline: $97k/employee/year. Target: +15%.

System: If crew exceeds +15%, bonus is 10% of delta.

Example: 10-person crew, target $1,117k, achieves $1,293k → Delta $176k → Bonus $17.6k → Extra margin $35k → Net to company +$17.6k.

Extended to 42 employees: Productivity +12% = +$49k/year net margin (essentially free).


3.3 Position Classification Audit

Every 2-3 years verify pay grade vs actual duties.

Example: Employee at Grade 3 doing Grade 2 work → From $3,910 to $3,350/month = $6,720/year.

If 6 employees over-classified: $40k/year. With proper documentation + training: $128k/year.

PHASE 3 TOTAL: $660k/year
Labor percentage: 45.2% → 43.2%


18-Month Plan Summary

Phase Duration Actions Savings/year Labor % Headcount
Phase 1 0-3 months 4 quick win actions $835k 48.1% 55
Phase 2 4-9 months Reorganization $1,320k 45.2% 47
Phase 3 10-18 months Efficiency $660k 43.2% 42
TOTAL 18 months 11 actions $2,815k 43.2% 42

To reach 38% target: revenue growth +8-10% or 2-3 natural departures in 2026-2027.


“I Can’t Fire People, They’re Like Family”

The plan requires ZERO layoffs. Everything is based on:

Statistically, over 18 months, 5-7 natural departures always occur.


Why 49.7% Is Lethal in Government Contracts

The mechanism: Government contracts require fronting 100% of costs (payroll $40k/month, equipment $30k, materials $50k). Payment comes 117-234 days later.

With 49.7% fixed costs: You pay $2.8M/month regardless, get paid 4-8 months later. Result: cash flow exhausted, you use suppliers as a “bank” (pay after 6-7 months). If suppliers cut off credit → immediate crisis.

Why reducing labor is vital: Not a question of margins, but financial survival. With optimized headcount (38% vs 49.7%), you better withstand government payment delays.

💡 The topic of managing receivables/cash flow in government contracts deserves separate analysis.


Conclusion: The Cost of Inaction

Today:

In 18 months (with plan):

Difference: +$2.8M margin without billing one more dollar.

Status quo (3 years):

Cost of inaction: The company in 4 years.

Domande Frequenti

What is a healthy labor cost percentage for construction companies?
Industry benchmarks for construction companies are 30-35% of revenue for labor costs. Top-performing companies (top 25%) achieve 28% or lower. Companies exceeding 40% face compressed margins and cash flow challenges, while those above 45% risk financial distress, especially with government contracts requiring upfront cost financing.
How can I reduce construction labor costs without mass layoffs?
Focus on: (1) Hiring freeze and natural attrition (resignations, retirements), (2) Early retirement incentive packages for near-retirement employees, (3) Cross-training workers for multiple roles, (4) Converting some full-time positions to part-time, (5) Hybrid staffing model with core permanent staff plus subcontractors for peaks, (6) Reducing overtime through better planning, (7) Outsourcing non-core functions like equipment maintenance. Most companies see 5-7 natural departures over 18 months without forced terminations.
Why are high labor costs especially dangerous in government construction contracts?
Government contracts typically require contractors to front 100% of costs (payroll, materials, equipment) but payment comes 4-8 months later. With labor costs at 49.7%, a company must pay $2.8M monthly in fixed costs while waiting for payment. This creates severe cash flow pressure, forcing reliance on supplier credit. If suppliers cut off credit during payment delays, the company faces immediate crisis even on profitable projects. Lower fixed labor costs (35-38%) provide crucial cash flow buffer.
What's the difference between AI agents and traditional construction management software?
Traditional construction software (Procore, Buildertrend, etc.) requires manual data entry - someone must input timesheets, invoices, costs, taking 2-3 hours daily. AI agent systems automatically import data from banks, accounting software, email, and cloud storage. They aggregate costs by project in real-time, send alerts when budgets are exceeded by 5%, and detect anomalies like duplicate purchases. Investment is $25-80K vs $5-8K/year for traditional software, but ROI is 3-8x for companies with 15+ projects, weak job costing controls, and margins under 10%.
How do you calculate revenue per employee for construction companies?
Divide total annual revenue by total number of employees. For example: $56.3M revenue ÷ 58 employees = $97,112 per employee. Industry benchmark is $165,000 per employee, with top performers achieving $220,000+. Low revenue per employee indicates overstaffing or poor productivity. Calculate this monthly to track trends and identify when headcount is growing faster than revenue.
What are effective productivity incentives for construction crews?
Best approach: Set baseline productivity targets (e.g., $97k revenue per employee), then offer crew bonuses for exceeding targets. Example: If 10-person crew has $1.117M target and achieves $1.293M (15% above), pay 10% of the delta ($17.6k bonus) to the crew. This generates $35k extra margin, netting company $17.6k after bonus. Keys to success: Make targets achievable, pay bonuses promptly, track by crew not individuals, and ensure crews have control over factors affecting productivity.
How do I present early retirement incentives to employees sensitively?
Frame it as an opportunity, not a termination. Say: "We're offering an incentive package so you can enjoy retirement with your family earlier. This is completely voluntary - take your time thinking about it and discuss with your family." Never say: "You're expensive" or "We need to reduce costs." Typical package: $30-40k one-time payment for employees 2-3 years from retirement eligibility. Present privately, give 2-4 weeks to decide, and emphasize it's their choice. ROI is typically 6-10 months.
What's a hybrid staffing model for construction companies?
Maintain a core of permanent employees (typically 70-75% of average capacity) for routine, year-round work. Use subcontractors for: (1) Seasonal peaks, (2) Specialized skills needed occasionally, (3) Geographic expansion, (4) Overflow capacity. Example: 42 permanent employees handle $36M base work (36.7% of revenue). Add $2.75M in subcontractor costs for peaks and specialties (5% of revenue). Total labor cost: 41.7% vs 49.7% with all-permanent staff. Provides flexibility without the fixed cost burden.
How much can construction companies save by reducing overtime?
Typical construction company with poor planning spends 8-12% of payroll on overtime (time-and-a-half). With $28M payroll, that's $2.24-3.36M, of which roughly $750k-1.1M is the overtime premium. Solutions: (1) Weekly planning by Friday for next week (not Monday morning), (2) Crew finish-early bonuses ("Finish by Friday = $850 bonus"), (3) Better material delivery coordination. Realistic savings: 40-60% reduction in overtime = $420-660k annually. Bonus: Better planning also improves crew morale and reduces turnover.
When should construction companies outsource equipment maintenance?
Outsource when: (1) You have fewer than 15-20 pieces of major equipment (not cost-effective for full-time mechanic), (2) In-house mechanic is idle 30%+ of time, (3) Local service shops can provide same-day or next-day service, (4) Mechanic has skills valuable elsewhere (can be reskilled as equipment operator or field worker). Typical savings: $51k full-time mechanic vs $44k annual service contract = $7k direct savings. Plus former mechanic generates $76k revenue in new role = $83k total benefit. Don't outsource if: equipment is specialized, you're in remote area without good service, or downtime costs exceed savings.
What hidden waste should construction companies look for first?
Before reducing headcount, recover: (1) 8-12% of hours lost to untracked idle time (waiting for materials, coordination delays, equipment issues), (2) 15-25% budget overruns detected too late (monthly reviews vs real-time tracking), (3) 3-5% of revenue in cost anomalies (duplicate purchases, paying above-market prices, unauthorized purchases). For $56M company, this represents $4.5-9.5M in recoverable waste. Requires: Daily job costing, real-time budget tracking, automated anomaly detection. Many companies save $500k-1.5M annually just eliminating these wastes, without touching headcount.
How long does it take to reduce construction labor costs safely?
Safe timeline is 18-24 months for significant reductions (10-15 percentage points). Phase 1 (0-3 months): Quick wins like hiring freeze, overtime reduction, part-time conversions. Phase 2 (4-9 months): Early retirements, cross-training, hybrid staffing model implementation. Phase 3 (10-18 months): Permanent efficiency gains through digitalization and productivity systems. Trying to do it faster (6-12 months) typically requires involuntary terminations, damages morale, loses institutional knowledge, and often costs more in severance/rehiring than it saves. Natural attrition provides 5-7 departures over 18 months without forced terminations.
