Labor Productivity & Rates Flashcards

In construction estimating, 'all-in' labor rates typically include which of the following on top of base wages?

Answer: Payroll taxes, insurance, and fringe benefits

All-in rates bundle the base hourly wage with employer-paid payroll taxes (FICA), workers' comp, general liability insurance, and fringe benefits.

When estimating labor for extreme heat conditions (above 95°F), a productivity adjustment of approximately what percentage is commonly applied?

Answer: 10–25% reduction

Industry standards typically apply a 10–25% productivity reduction for extreme heat, depending on humidity and task intensity.

Which document is most commonly used as a primary reference for labor unit costs in US construction estimating?

Answer: RSMeans Cost Data

RSMeans is the industry-standard database for labor unit costs, material prices, and crew compositions used by US estimators.

A 'crew day' unit of measure assumes how many hours of productive work?

Answer: 8 hours

A standard crew day is based on an 8-hour productive work shift, which is the most common baseline in RSMeans and similar references.

Labor burden as a percentage of base wages typically ranges from:

Answer: 25% to 45%

Labor burden (taxes, insurance, fringes) generally adds 25–45% to base wages depending on trade, location, and union status.

When a project requires overtime at 1.5× pay for hours beyond 8 per day, what is the effective hourly cost for the 9th hour if the base rate is $40/hour?

Answer: $60/hour

Overtime pay at 1.5× means $40 × 1.5 = $60 per hour for each hour beyond 8 in a day.

A 'man-hour' in construction estimating is best defined as:

Answer: One worker performing one hour of labor

A man-hour (or labor-hour) represents the amount of work one person can perform in one hour, regardless of crew size.
