What Is Workers Comp Class Code 6018?
NCCI class code 6018 covers Pipe Laying — Sewer & Water Mains in Florida. This classification is used by workers' compensation carriers to determine premium rates based on the relative injury risk of workers in this occupation. The Florida NCCI rate for code 6018 is $2.14 per $100 of payroll, placing it in the high-risk tier.
Covers workers installing underground sewer and water main pipelines. At $8.12/$100, a worker earning $1,000/week costs $81.20/week in workers comp.
Because code 6018 is a construction classification, Florida law requires workers' compensation coverage from the first employee. Construction employers cannot use the 4-employee threshold that applies to non-construction businesses.
What Does This Rate Mean in Real Dollars?
At $8.12/$100, a worker earning $1,000/week costs $81.20/week. Annual cost for $180,000 payroll: ~$14,616.

Top Workers Comp Risks for Code 6018
The NCCI rate for this classification reflects the frequency and severity of workers' compensation claims historically filed by workers in this occupation. The primary risks include:
Florida Workers Comp Requirements for Code 6018
Florida Statute Chapter 440 governs workers' compensation requirements. For construction employers classified under code 6018, coverage is required with 1 or more employees — including the business owner unless a valid exemption is on file with the Florida Division of Workers' Compensation.
The Florida Division of Workers' Compensation conducts random job site inspections and can issue an immediate stop-work order if coverage is not current. The penalty is equal to twice the amount of premium that should have been paid, plus $1,000 per day per employee while uninsured.
OSHA Standards That Apply to Code 6018
Workers in this classification are subject to the following OSHA standards. Violations of these standards are the most common triggers for workers' compensation claims in this trade.
29 CFR 1926.651
Specific Excavation Requirements: For sewer and water main pipe laying, this requires locating and marking underground utilities before digging, providing safe access/egress (ladders) in trenches 4 ft or deeper, keeping spoil piles and equipment at least 2 ft from the edge, controlling water accumulation, protecting employees from traffic, and having a competent person inspect excavations daily.
29 CFR 1926.652
Requirements for Protective Systems: Pipe-laying crews must slope, shore, or shield (trench boxes) any trench 5 ft or deeper unless in stable rock, and use systems designed per tabulated data/engineered plans suitable for the soil conditions encountered on sewer/water main jobs.
29 CFR 1926.650
Excavations (Scope, Application, and Definitions): Establishes Subpart P coverage for trenches/excavations used in laying water and sewer mains and defines the “competent person” whose continuous hazard evaluations and authority to correct hazards are required on these sites.
29 CFR 1926.602
Material Handling Equipment: Governs excavators, loaders, backhoes, and other earthmoving equipment used to trench and set pipe; requires seat belts, backup alarms or observers when vision is obstructed, and safe operation/maintenance to protect ground workers in the trench.
29 CFR 1926.200 and 1926.201
Accident Prevention Signs/Tags and Signaling: Requires proper traffic control signs, barricades, and qualified flaggers when pipe-laying occurs in public rights-of-way, consistent with the MUTCD, to prevent struck-by incidents during main installation and restoration.
Florida Stop-Work Order Cases — Code 6018
The Florida Division of Workers' Compensation (DFS) actively enforces coverage requirements. Below are representative enforcement cases involving businesses classified under code 6018.
Miami-Dade County (2023): DFS investigators found a pipe-laying crew installing an 8–10 ft deep sewer main along a city street without workers’ comp and using 1099 “laborers” in the trench. Penalty assessed at $1,000 per day per employee for 5 employees over 15 days ($75,000) plus twice the estimated unpaid premium of $19,500, totaling $94,500.
Polk County (2022): A small utility contractor laying a 12-inch water main along US-98 had a lapsed workers’ comp policy while operating with a 4-person crew and active dewatering. DFS issued a stop-work order and penalties of $1,000/day/employee for 9 days ($36,000) plus twice the unpaid premium of $7,800, for a total of $43,800.
Duval County (2024): During a subdivision water/sewer main install in Jacksonville, DFS discovered a subcontractor misclassified 6018 pipe-laying labor as low-risk work and paid several trench workers in cash. Penalties included $1,000 per day per employee for 8 employees over 20 days ($160,000) plus twice the unpaid premium of $28,000, totaling $188,000.

Why Standard Carriers Decline Code 6018
Many standard insurance carriers restrict or decline coverage for businesses classified under code 6018. Understanding these declination triggers helps you find the right coverage path.
High trench-collapse severity potential on 6018 jobs (deep cuts, variable soils, dewatering) without a documented protective-system plan and daily competent-person inspections; many standard markets won’t take the cave-in exposure.
Frequent right-of-way work and lane closures create significant struck-by/traffic control exposure; carriers may decline if the contractor lacks a formal MOT/flagging program or relies on general labor in live traffic.
Heavy equipment working in close proximity to ground crews (excavators, pipe lasers, trench boxes) and lifts for large-diameter ductile iron or concrete pipe; adverse loss history with struck-by and crush injuries leads to surcharges or declinations.
Subcontractor/1099 reliance common in 6018 with poor COI management; uninsured or misclassified subs and night/emergency main-break work (24/7 response) are red flags for admitted carriers, especially for new ventures or accounts with coverage lapses.
Common Workers Comp Audit Mistakes for Code 6018
Year-end workers comp audits frequently result in unexpected additional premiums for businesses classified under code 6018. These are the most common audit mistakes to avoid.
Splitting crew payroll between 6017 (excavation/grading) and 6018 (pipe laying) without contemporaneous time records; NCCI will assign the entire employee’s pay to the highest-rated class (6018) if records don’t clearly separate hours by task each day.
Classifying working foremen/superintendents as 8810 clerical or 8742 outside sales even though they visit jobs, enter excavations, or direct trench operations; those employees belong in 6018 when they go to the site.
Moving paving/backfill/restoration payroll to 5506 (street/road) after pipe installation; for utility main projects, backfill, compaction, and patching incidental to the trench are included in 6018 unless subcontracted with proper COIs.
Failing to include uninsured subs and cash/day labor used for trench crews; without valid workers’ comp certificates, the auditor will add that labor to 6018 payroll. Overtime is another trap—contractors often back out the full overtime amount instead of only the premium portion, causing disputes and additional premium due.
Experience Mod (EMR) & PEO Advantage
For 6018, frequent strains from handling ductile iron/HDPE, struck-by incidents around excavators, and the potential for severe trench-related claims push the experience mod up—especially because frequent medical-only and lost-time claims inflate primary losses that weigh heavily in the EMR. A PEO places you on a large master policy and brings trench safety resources, return‑to‑work, and tighter claims handling that reduce claim frequency/severity and help stabilize or lower your mod over time—even if a high mod has standard carriers walking away.
