While “Journeyman” remains the most commonly searched and widely recognized industry term, many government agencies, unions, and labor organizations now officially use the gender-neutral term “Journeyperson” or “Journeyworker” in prevailing wage determinations, apprenticeship standards, and collective bargaining agreements.
Qualified Apprentice
A worker enrolled in a DOL-registered apprenticeship program who is learning a construction trade under the supervision of a journeyperson. Qualified apprentices may be paid a lower prevailing wage rate (typically a percentage of the journeyperson rate) as permitted under Davis-Bacon regulations.
Qualified Plan (Retirement)
An employer-sponsored retirement savings plan that meets IRS requirements under the Internal Revenue Code — such as a 401(k) or pension plan — and receives favorable tax treatment. Construction companies and unions commonly offer qualified plans as fringe benefits.
R
Reporting Time Pay
Compensation required under certain state laws — especially California and some West Coast jurisdictions — when an employee reports to work but is provided fewer hours than scheduled. Typically requires payment of at least half the scheduled shift at the employee's regular rate.
Risk Management Plan
A formal document identifying potential risks to a construction project — including safety, schedule, financial, and compliance risks — along with assigned owners, likelihood ratings, and mitigation strategies. Risk plans are updated throughout the project lifecycle.
RFP (Request for Proposal)
A competitive procurement document issued by an owner inviting contractors to submit detailed proposals for a construction project, including proposed approach, team qualifications, schedule, and pricing. Unlike an IFB, an RFP evaluates qualitative factors in addition to price.
RFI (Request for Information)
A formal written question submitted by a contractor to the design team or owner seeking clarification on contract documents, drawings, or specifications. RFIs document ambiguities and may support change order claims if the response results in additional cost or schedule impact.
Right-to-Work Law
A state law that prohibits requiring union membership or payment of union dues as a condition of employment. Currently in effect in 27 states, right-to-work laws affect union organizing, CBA enforcement, and open shop competition in the construction industry.
Reportable Incident
A work-related injury, illness, or near-miss that must be documented and reported under OSHA recordkeeping rules (Form 300), to workers' compensation carriers, or to project owners. Timely, accurate incident reporting is essential for EMR management and contractor prequalification
Registered Apprenticeship Program
A DOL-approved structured training program combining on-the-job learning with related technical instruction for construction trades. Workers in registered programs earn progressive wages and are eligible for reduced prevailing wage rates during training. Contractors must meet apprenticeship ratio requirements on many public works projects.
Regular Rate of Pay
The hourly rate used as the basis for calculating overtime under the FLSA — includes base wages plus certain additional compensation such as shift differentials, piece-rate earnings, and non-discretionary bonuses. Failing to include all required components in the regular rate is a common overtime compliance violation.
Retainage
A percentage of each progress payment (typically 5–10%) withheld by the owner or GC from a contractor or subcontractor until the project reaches substantial completion or final acceptance. Retainage protects the owner against incomplete or defective work and is a significant cash flow challenge for contractors.
S
Site Safety Plan
A project-specific written document outlining the safety protocols, emergency procedures, hazard controls, and training requirements that will govern a construction site. Required on most large commercial and public projects and reviewed by OSHA during inspections.
Supplemental Unemployment Benefits (SUB)
Employer-funded payments made to laid-off construction workers to supplement state unemployment insurance benefits, bringing their total income closer to their regular wages. SUB plans are common in union agreements for trades with high seasonal layoff rates.
Subcontractor Default Insurance (SDI)
A specialty insurance product purchased by GCs as an alternative to requiring subcontractors to obtain performance and payment bonds. SDI provides coverage if a subcontractor defaults on their work, with the GC managing the claim directly with the insurer.
Schedule of Values (SOV)
A detailed breakdown of the total contract price allocated across the major components or phases of a construction project. The SOV is the basis for monthly pay applications and is reviewed and approved by the owner or architect before the first billing.
Subcontractor
A specialty trade contractor hired by the general contractor to perform a defined scope of work on a construction project — such as electrical, plumbing, HVAC, drywall, or concrete. Subcontractors are bound by their subcontract agreement and the prime contract requirements including prevailing wage and certified payroll obligations.
T
Turnaround Time (Payroll)
The elapsed time between the close of a payroll period and the date employees receive their paychecks or direct deposits. Minimizing payroll turnaround time is critical in construction to maintain workforce satisfaction and comply with state prompt payment requirements.
Tiered Wage Rate
A wage structure — common in union CBAs and prevailing wage schedules — where workers are paid at different rates based on their classification level, years of experience, or apprenticeship year. Foremen or lead workers typically earn a premium above the journeyman rate.
Total Compensation
The complete value of all compensation provided to a construction employee — including base wages, overtime, bonuses, per diem, employer-paid health insurance, retirement contributions, workers' compensation, and payroll taxes. Used in benefits benchmarking and union negotiations.
Termination Pay
The final paycheck issued to a construction employee upon separation from employment — whether voluntary, involuntary, or layoff. State laws strictly govern the timing of final pay: California requires same-day payment for involuntary termination; other states allow 72 hours to the next regular payday.
Travel Time Pay
Compensation owed to construction workers for time spent traveling between job sites during the workday or from a designated meeting point to a remote project. Whether travel time is compensable depends on FLSA rules, state law, and CBA provisions.
Tax Withholding
The amount of federal, state, and local income taxes deducted from a construction employee's gross wages each pay period and remitted to the applicable tax authorities by the employer. Withholding is based on the employee's W-4 filing status and allowances.
Total Recordable Incident Rate (TRIR)
An OSHA safety metric calculated as (number of recordable incidents × 200,000) ÷ total hours worked. TRIR measures a contractor's safety performance relative to industry averages and is a standard prequalification criterion for owners and GCs.
Trade Classification
The specific job title or craft category assigned to a construction worker under prevailing wage law — such as Carpenter, Ironworker, Operating Engineer, or Laborer. The correct trade classification determines the required prevailing wage rate and fringe benefits owed to each worker.
Timecard
A record — paper or digital — documenting the hours a construction worker was on site each day, including start time, end time, meal breaks, job site, and cost code. Timecards are the primary source document for payroll processing and must be retained for at least three years under FLSA.
U
Utilization Rate
A productivity measure expressing the percentage of a worker's or piece of equipment's available time that is spent on billable or productive work versus idle or non-productive time. Low utilization rates on construction projects signal inefficiency, overstaffing, or scheduling problems.
Unlicensed Contractor
A contractor performing construction work without the required state or local contractor's license. Hiring unlicensed subcontractors exposes GCs to liability, voids insurance coverage, and can result in project shutdowns, fines, and personal liability for owners.
Union Reporting
The periodic submission of hours worked and fringe benefit contribution data to local union trust funds by signatory contractors. Reports must reconcile with certified payroll submissions and are subject to audit by the union's benefit fund administrators.
Union Fringe Benefits
Mandatory employer contributions to jointly-administered trust funds required by union CBAs — including health & welfare, pension, vacation, apprenticeship training, and industry advancement funds. Fringe contributions are expressed as hourly rates and are a major component of union labor cost.
Union Dues
Periodic fees paid by union members to their local union — typically a flat monthly amount or a percentage of wages — to fund union operations, organizing, legal representation, and collective bargaining. On non-right-to-work states, dues or equivalent fees may be required as a condition of employment.
Union Collective Bargaining Agreement (CBA)
A legally binding written contract negotiated between a construction union and one or more contractors or employer associations specifying wages, hours, working conditions, fringe benefits, grievance procedures, and work rules for union members. CBAs are the foundation of union construction workforce management.
V
Verified Compliance Status
A formal confirmation that a contractor has met all applicable licensing, insurance, prevailing wage, and safety certification requirements for a project. Owners and GCs verify compliance status during prequalification and periodically throughout the project.
Voluntary Benefits
Optional employee benefits offered by construction employers beyond legally required or union-mandated benefits — such as supplemental life insurance, critical illness coverage, identity theft protection, or legal services. Voluntary benefits enhance recruitment and retention without significant employer cost.
Voluntary Termination
An employee-initiated separation from employment — commonly called a resignation or quit. In construction, voluntary terminations during an active project may require workers to give advance notice under CBA terms. State law governs the timing of final paycheck delivery following a voluntary quit.
Variance Analysis
The systematic comparison of actual project costs and labor hours against the original budget to identify and explain deviations. Construction variance analysis — by cost code, trade, and project phase — is a core tool for project control and forecasting.
Verified Payroll
A payroll record that has been reviewed and confirmed to be accurate against applicable prevailing wage rates, trade classifications, hours worked, and fringe benefit contributions — the basis for a certified payroll report. Verification is a critical step before submitting CPRs to avoid penalties.
W
W-9 Form
An IRS form collected by a GC or owner from independent contractors, subcontractors, and vendors before payment — used to obtain their taxpayer identification number (TIN) for 1099 reporting purposes. Failure to collect W-9s can result in backup withholding obligations.
W-2 Form
The annual IRS wage and tax statement that construction employers must provide to each employee and file with the SSA by January 31 each year, reporting total wages paid, federal and state taxes withheld, and benefit contributions for the prior calendar year.
Weekly Payroll
A payroll cycle in which employees are paid every week — 52 pay periods per year. Many union CBAs and state laws require weekly payroll for construction workers. Weekly payroll improves cash flow predictability for workers and reduces the risk of large wage-and-hour liability accumulating over longer periods.
Work Breakdown Structure (WBS)
A hierarchical decomposition of a construction project's total scope of work into manageable phases, deliverables, and work packages — used as the basis for scheduling, cost estimating, and labor allocation. Each WBS element can be assigned cost codes for labor tracking purposes.
Workforce Management
The integrated set of processes and technology used to plan, schedule, track, and manage a construction company's labor resources — including hiring, onboarding, time tracking, payroll, compliance, and performance management. Effective workforce management is critical for project profitability and regulatory compliance.
Withholding Allowance
The number claimed by an employee on their W-4 form that reduces the amount of federal income tax withheld from each paycheck. Construction employers use withholding allowances to calculate the correct federal tax withholding per the IRS withholding tables.
WH-347 Form
The US DOL's standard certified payroll report form required on federally funded prevailing wage construction projects. WH-347 documents each worker's name, SSN (partial), trade classification, hours by day, gross wages, deductions, and net pay — submitted weekly to the contracting agency or designated prime contractor/project administrator.
Workers' Compensation Insurance
A mandatory insurance program providing medical benefits and wage replacement to construction workers injured on the job. In construction, workers' comp premiums are based on payroll, trade classification, and the employer's experience modification rate (EMR). Failure to carry workers' comp is a serious legal violation in all states.
Wage Theft
The illegal practice of failing to pay workers all wages legally owed — including minimum wage, overtime, prevailing wages, or agreed-upon rates. Wage theft in construction includes off-the-clock work, illegal deductions, misclassification, and falsified timecards. Penalties include back pay, liquidated damages, and criminal prosecution.
Wage Determination
An official decision by the US DOL or state labor agency establishing the minimum prevailing wage rates and fringe benefit rates required for each trade classification on a public works construction project. Wage determinations are project-specific and must be posted on the job site.
Y
Youth Apprenticeship
A construction industry workforce development program that allows high school students to earn credit, receive trade training, and work in paid construction apprenticeships. Youth apprenticeship programs are an important pipeline strategy for addressing skilled labor shortages in the industry.
Year-to-Date (YTD) Earnings
The cumulative total of wages, overtime, bonuses, and other compensation paid to a construction employee from January 1 through the current pay date. YTD figures are critical for tracking progress toward Social Security wage base limits and annual benefit thresholds.
Year-End Payroll Reconciliation
The process of verifying that all payroll transactions processed throughout the calendar year are accurate and complete before generating annual tax forms — including W-2s, W-3s, and 940/941 filings. Year-end reconciliation identifies discrepancies between payroll records and tax deposits before IRS deadlines.
Z
Zero Tolerance Policy
A workplace rule on a construction site that mandates immediate removal and termination — with no second chance — for violations of critical safety rules such as working without fall protection at height, operating equipment under the influence, or disabling safety devices.
Zero Incident Goal
A construction safety philosophy and formal program commitment to achieve zero workplace injuries, illnesses, and near-misses on a project or across the company. While debated as a metric, zero incident programs drive proactive hazard identification, behavioral safety training, and leadership accountability.
