Choose the rate basis for the plan
Identify whether the estimate uses an internal ownership rate, a supplier rental quote, or a subcontracted equipment price. Record the equipment class, capacity, attachments, rate period, quote date, and minimum term.
The selected machine should fit the work method described in the estimate. Use the construction equipment cost estimating as the related control and keep the record with the estimate revision under review.
Match time charges to production
Separate productive hours, standby, maintenance windows, and calendar rental duration. A daily or monthly quote cannot be extended only from productive hours when the machine remains on site. Compare estimated duration with the schedule and number of available work fronts.
AACE recommended practices offer general estimating references. The project documents, contractor procedures, and approved estimate remain the controlling basis for the decision.
| Review field | Required record |
|---|---|
| Equipment | Class, capacity, and attachments |
| Rate | Source, period, and minimum |
| Time | Productive, standby, and duration |
| Extras | Mobilization and included costs |
Reconcile inclusions and mobilization
Check delivery, pickup, assembly, permits, fuel, consumables, wear items, taxes, insurance, and operator cost. Mark which items the rate already includes.
Keep mobilization as a visible cost so it is not repeated in both the equipment line and project indirects. Use the estimate labor crew composition review as the related control and keep the record with the estimate revision under review.
