A rented excavator has been on site since Wednesday and the foreman asks to keep it another week. To calculate construction equipment utilization for that decision, divide verified working hours by available shift hours and multiply by 100. Build the same measure for a comparable owned unit so you can see how much ready capacity each supplied.
Track the rental’s time on hire alongside its shift utilization (including nights or weekends when the hire window covers them). Dispatch needs to know whether it could put the excavator to work during a shift. The person approving the rental needs to see how much of the time the business kept the machine translated into use.
Define the hours the fleet could supply
For an owned machine, start with the shifts during which it was in service and in scope for the fleet. Subtract approved periods when the asset could not be dispatched, such as an overlapping shop hold. Intersect the hold with the shift before subtracting time. An overnight repair between working shifts need not remove any daytime capacity. Keep the hold time visible next to the utilization result so the rate cannot hide a machine that was unavailable most of the week.
For a rental, intersect the shifts with the verified possession window. Start from delivery or documented handoff and stop at return or release, according to your policy. Apply confirmed service holds the same way you do for owned equipment. Keep the contract and invoice interval separately, because billing can begin before delivery or continue after you release a machine for pickup.
Leave an available but unassigned asset in the denominator. Removing its hours because nobody booked it erases the unused capacity you are trying to find. If the site shuts down, use a recorded calendar revision and keep it with the report. The construction equipment management software comparison covers the dispatch and service records that can establish when an asset became assignable.
Check what the meter measures
Caterpillar’s VisionLink Productivity documentation shows separate working and idle hours. Bobcat’s telematics API documentation shows that cumulative operating hours and cumulative idle hours are different fields and that access to idle hours varies by subscription. Check what each feed defines before comparing assets or combining totals.
If a feed defines idle time as a subset of engine-on time, subtract the idle delta from the engine-on delta using the same time boundaries. Treat the result as a proxy for working time unless a production signal or operator record supports the classification. Travel, warmup under load, or operating an attachment can make the proxy differ from your definition of job work. For battery-powered or uninstrumented equipment, use a compatible work signal or reviewed operator entry and label the source.
Retain the asset ID, serial number, reading time, and both meter readings used for each delta. A counter reset, replacement machine, or missing boundary reading makes a difference between two numbers unreliable. Show coverage or flag the affected period. Keep a missing observation distinct from an observed zero, because they lead to different rental decisions.
Compare an owned excavator and a rental in the same week
In this hypothetical week, an owned excavator is in the fleet for the full calendar window. An equivalent rental arrives Wednesday at 06:00 and leaves Friday at 18:00. The site works five eight-hour shifts from Monday to Friday. The rental’s possession window contains three of them, and the owned excavator spends eight scheduled hours on a service hold. Assume the meter increments shown below fall within the available shifts and the site logs confirm the non-idle hours were working hours.
| Same reporting week | Owned excavator | Rented excavator |
|---|---|---|
| Calendar hours in service or on hire | 168 | 60 |
| Scheduled shift hours in scope | 40 | 24 |
| Service hold during scheduled shifts | 8 | 0 |
| Available shift hours | 32 | 24 |
| Engine-on hours within available shifts | 24 | 8 |
| Idle hours within available shifts | 6 | 3 |
| Verified working hours | 18 | 5 |
| Working hours ÷ available shift hours | 56.25% | 20.83% |
| Working hours ÷ calendar hours | 10.71% | 8.33% |
The rental worked five of twenty-four available shift hours. Dividing the same five hours by sixty calendar hours answers a different question about its time on hire. Show the hour totals before making a decision. An upcoming excavation could justify keeping the machine even after a light week. A conflict in the planned work can also explain why the rental was available and the crew could use neither machine.
To summarize comparable machines by available shift hours, divide the sum of working hours by the sum of available shift hours. A mean of per-machine percentages gives a short rental as much influence as a machine available all week. Rental companies also use an on-rent time measure for their own fleets, as defined in the American Rental Association’s Rental Market Metrics. Use the label to distinguish that measure from contractor jobsite work.
Keep equipment charges tied to the job and period that incurred them. A billed rental day or interjob transfer can affect the construction job cost report even when it contributes no verified working hours.
Inspect the hours in a fleet export
Use a supported source to see which asset IDs and timestamps came through with the working and idle counters.
Where Permute fits in the rental review
Permute is the context layer we sell between business records and the AI tools people use. We can connect supported spreadsheet and telematics exports, then join readings, service holds, and possession intervals using the serial number and dates when the machine was assigned.
We use the fleet’s declared calendar and work signal so dispatch and finance can see the hour measures in the same report. Each retains its definition, source timestamps, and coverage.
A fleet manager can ask which rentals with a renewal coming up had low working time or missing readings and get the relevant asset, contract dates, and evidence they’re permitted to see.
Keep dispatch and rental approvals with their owners
We read data from supported sources and do not write back into systems of record, release equipment from a service hold, or approve a renewal. The fleet team determines whether a signal represents job work and checks the next schedule before moving an asset.
Read the hours before renewing a rental
Construction equipment utilization shows how much available shift time became work when the numerator and denominator use the same boundaries. The owned excavator’s service hold and the rental’s midweek arrival change the hours each could supply. Keep calendar or billed time beside the shift result when you review a hire. When meter coverage is missing, verify the work before acting on the percentage.
Review one equipment renewal with Permute
Bring a rental period, the corresponding shift plan, and a meter export to see how the records fit together.
Questions about comparing construction equipment hours
What if an asset has zero available shift hours?
Show the utilization rate as unavailable and report the reason the denominator is zero. A service hold for the whole window needs different follow-up from a healthy machine that had capacity and did no work.
What if the rental supplier sends a replacement under the same contract?
Keep the contract relationship and timestamp each serial number’s possession interval. Calculate meter differences per machine, then combine eligible time at contract level without counting overlapping custody twice unless both units were available for work.
Can I calculate the rate with billed days and working hours?
Convert to a common unit and label the result as working time per billed time, applying the contract’s billing rules. Use the shift denominator for dispatch comparisons because billed periods can include time outside staffed shifts.
