Estimating

What is an equipment rental rate in construction?

An equipment rental rate is the price per hour, day, week, or month charged for a piece of construction equipment, whether rented from a vendor or charged to the job from the contractor's own fleet.

Every machine on a job has a rate. If it came from a rental house, the rate is on the rental contract. If the contractor owns it, the rate is an internal number meant to recover ownership costs (purchase price, financing, depreciation, insurance, storage) and operating costs (fuel, maintenance, wear parts) through the jobs that use it. Both kinds of rates end up in estimates, job costing, and change order pricing.

Rental house rates versus internal rates

Two kinds of equipment rates
Rental from a vendorOwned equipment charged to the job
Who sets itThe rental companyThe contractor, often from its own cost records or a published schedule
Typical unitsDay, week, four-week month; weekly and monthly usually cheaper per dayHour or day, sometimes split into standby and operating
What is includedMachine only; fuel, delivery, damage waiver, and environmental fees often extraWhatever the contractor's rate buildup covers
OperatorUsually not includedUsually separate labor cost

Rental terms matter as much as the rate. A machine rented by the week and kept a day longer often bills at the daily rate for the extra day. Pickup is not the same as off-rent; the clock usually stops when you call it off, not when the truck shows up.

Rates on change orders and government work

Owners push back hardest on equipment rates in change orders, so many contracts specify how they are set: a percentage of a published rental guide, actual invoices, or the owner's own schedule. On federal cost-based pricing, FAR 31.105(d)(2) says actual cost data from the contractor's records is used when ownership and operating costs can be determined. Predetermined schedules, such as the Army Corps of Engineers Construction Equipment Ownership and Operating Expense Schedule, may be used when actual data cannot be. The same section says reasonable costs of renting construction equipment are allowable, but major repair and overhaul costs for rented equipment are not.

A worked example

Say an earthwork sub prices a change order for 3 extra days of excavation on a $1.1 million site package. The excavator is owned, and the sub's internal rate is $95 an hour for operating time. A rented compactor costs $310 a day plus a $150 delivery charge each way (made-up figures for illustration). The change order shows 24 excavator hours at $95, 3 days of compactor rental at $310, two delivery charges, operator labor at the burdened rate, and markup per the contract. The owner's rep can check every number against a time card or an invoice.

Common mistakes

  1. Charging owned equipment at retail rental rates when the contract calls for cost.
  2. Not tracking idle and standby time, then fighting over it later.
  3. Leaving rentals on rent after the work is done. Call them off and record the call-off number.
  4. Forgetting fuel, delivery, and damage waiver when comparing rental quotes.

Frequently asked questions

How are construction equipment rental rates usually quoted?

By the day, week, and month, with longer terms costing less per day. Some equipment is also rented by the hour. Fuel, delivery, and damage waiver are often extra.

What rate should I use for my own equipment?

A rate that recovers ownership and operating costs from your own records. On cost-based federal pricing, FAR 31.105(d)(2) prefers actual cost data and allows predetermined schedules only when actual data cannot be determined.

Can I charge standby time?

Only if the contract allows it. Many contracts and published schedules pay standby at a reduced rate, so read the change order and equipment pricing clauses.

Is operator labor part of the equipment rate?

Usually not. Operator wages and burden are priced as labor. Some rental companies offer operated rentals at a combined rate.
