Workers’ compensation code 5606 is the classification for construction executives, project managers, construction managers, and construction superintendents who run projects indirectly through foremen or subcontractors rather than directing laborers themselves. It carries a low rate because the hazard is administrative, not physical, but the eligibility rules are strict and unforgiving: a single audit finding that an employee doesn’t qualify can reclassify that person’s entire annual payroll into the highest-rated construction code on the policy.
Who Qualifies for Code 5606
The code covers executive-level supervisors whose job is to run construction projects from a main office or job-site trailer. They hold regularly scheduled meetings with foremen and superintendents to set daily or weekly objectives, travel between sites to check progress, consult with the on-site supervisor in charge, and deliver communications to on-site leadership. The work is managerial and happens through intermediaries.
Code 5606 also extends to management-level employees such as safety managers and project engineers who walk through active sites but do not supervise construction operations. For these non-supervisory managers to qualify, either the employer has to maintain the required supervision hierarchy over construction crews, or all construction work must be subcontracted to licensed contractors.
Some roles that look similar fall outside the code. Employees whose site visits are limited to pre-construction estimating, outside sales, or client relations are classified under different codes. The test is function, not title: 5606 is for people actively managing ongoing construction through others, not people who happen to visit a site for another business purpose.
The Indirect Supervision Rule
Supervision under 5606 has to be indirect. The executive cannot have direct charge over workers at a construction or erection site. At least one full layer of management, meaning foremen, superintendents, or job supervisors, must stand between the person classified under 5606 and the laborers performing the work. Some states require two full levels, so confirm the requirement with your insurer or state rating bureau before relying on the classification.
Job titles do not matter. An auditor looks at what the person actually does, not what their business card says. A “Vice President of Operations” who stands on a roof telling workers where to lay shingles is a roofer for classification purposes, and the code will not protect that payroll.
Managing Through Subcontractors
Code 5606 does not require the executive to supervise the contractor’s own employees. It also applies when a construction executive manages projects entirely through subcontractors, but with a strict condition: every subcontractor must have an on-site superintendent or foreperson at each job site the executive visits or oversees.
If even one subcontractor lacks a foreperson at any site the executive visits during the policy year, the executive’s entire payroll for that year is reassigned to the highest-rated construction classification on the policy. Not just the payroll for the period when the gap existed. The full year. A sole proprietor or owner-operator working as a subcontractor without any employees of their own creates the same problem, because that subcontractor has no foreperson to serve as the buffer between the executive and the work.
Contractors who subcontract all construction operations and develop no payroll under any construction classification can still use 5606 for their executive supervisors, provided those executives work exclusively through licensed subcontractors and each subcontractor keeps on-site supervision in place.
No Construction Work, Ever
The restriction on physical labor is absolute. Employees classified under 5606 do not perform construction work at job sites. There is no incidental-task exception, no five-minute grace period, and no “helping out” allowance.
That means no picking up tools, no operating machinery, no moving materials, and no hands-on demonstrations of construction techniques. Even directing a worker’s physical movements in real time, instead of communicating objectives through a foreman, pushes the supervisor out of the classification. The line sits between telling a superintendent “that wall needs to be done by Thursday” and telling a worker “move that beam six inches to the left.” The first is indirect management. The second is direct supervision of construction, and it disqualifies 5606.
Payroll Cannot Be Split
Unlike some classifications where an employee’s wages can be divided between codes based on time spent on different tasks, 5606 does not allow splitting. You cannot assign 80% of an employee’s payroll to 5606 and 20% to a construction code. The employee either qualifies for 5606 for the entire policy period, or they don’t qualify at all.
That all-or-nothing rule is what makes the manual-labor prohibition so expensive. A project manager who spends 95% of the year at a desk but picks up a nail gun during one busy week doesn’t lose just that week’s lower rate. The entire year’s payroll moves to a construction code. Construction rates can run ten or twenty times higher than the 5606 rate per $100 of payroll, so a brief lapse can produce a painful audit bill.
Code 5606 Versus Clerical Code 8810
Companies sometimes ask why office-based project managers can’t simply be classified under code 8810, the standard clerical office code used across all industries. Code 8810 requires the employee to work exclusively in an office environment without exposure to the operational hazards of the business. A construction executive who visits active job sites, even just to check progress, is exposed to those hazards and cannot qualify for the clerical code.
Code 5606 fills that gap. It recognizes that these executives visit construction sites and face some hazard, but not the same hazard as the workers performing the building. Both codes act as companion codes, meaning they can appear on a policy alongside any trade-specific construction classification, and both have strict eligibility rules that keep administrative and physical-labor payrolls separated. The short version: 8810 is for people who never leave the office, and 5606 is for people who leave the office but never touch the work.
How Rates and the Experience Mod Work
Workers’ compensation premiums start with multiplying the rate for each classification code by every $100 of payroll assigned to that code. A rate of $1.50 on $300,000 in annual payroll produces $4,500 in base premium for that classification. Code 5606 rates sit among the lowest in construction because the physical hazard is minimal.
Once the base premium is calculated across all codes on a policy, the insurer applies an experience modification rate, often called a “mod.” The mod adjusts premium based on the employer’s own claims history relative to similar businesses. A mod of 1.00 is average; a mod below 1.00 produces a discount, and a mod above 1.00 increases the premium.1National Council on Compensation Insurance. ABCs of Experience Rating
Keeping executive supervisors properly classified under 5606 instead of a higher-rated construction code can save thousands of dollars per employee per year, but only if the classification holds up at audit.
Recordkeeping and Audit Preparation
Every workers’ compensation policy is subject to a year-end premium audit, and 5606 draws extra scrutiny because the rate gap is so large. Keep payroll for 5606-classified employees completely separate from payroll assigned to construction codes in your accounting system. That separation is what lets an auditor verify the dollar amounts without guesswork.
Beyond payroll, the documentation that protects the classification includes written job descriptions stating that the employee does not perform construction work, organizational charts showing the layers of supervision between the executive and the workforce, and meeting schedules or logs showing regular meetings in office or trailer settings. If the company uses subcontractors, records confirming that each subcontractor maintained an on-site foreperson throughout the policy period matter just as much.
When an auditor reclassifies payroll out of 5606, the employer owes the premium difference retroactively for the entire policy year. That bill arrives after the work is done and the money is spent. The contractors who come through audits cleanly treat documentation as an ongoing task, and they confirm that the organizational structure supports the classification before the policy starts, not when the auditor shows up.
