Define the rental period check

Treat one rental item as the review unit. Record the source before changing the estimate so the submitted or governing basis remains available.

Use these working fields: Equipment item, Billing unit, Mobilization date, Active and standby time, Return date. Keep source facts separate from reviewer decisions.

Set the review basis

Freeze the estimate version and the source documents used for the check. Name the equipment estimator, reviewer, and release supported by the work.

Coordinate the boundary with the equipment rental rate estimate review. Use that guide for connected scope while keeping this control focused.

Check each rental item

Place the equipment against the current work sequence, identify the supplier billing unit, and count each chargeable period. Include mobilization and return constraints, then show standby separately from productive use.

Retain equipment item and billing unit as the baseline. Record any correction in a separate decision field.

Work through an exception

Equipment needed for two separated work windows may remain on site or be returned between them. Compare those scenarios using the quoted billing and transport terms instead of choosing a universal duration.

Complete the record with active and standby time and return date. State the exact value carried into the estimate.

Distinguish errors from valid exceptions

Do not divide working hours by a nominal shift and call the result a rental period. Calendar rules, minimum periods, weekends, and return cutoffs can change the billed duration. The AACE recommended practices can help the team select controls that fit the estimate class and project requirements.

Close the finding

Record the original value, checked value, variance, source, owner, and disposition. Recalculate affected detail lines and rollups before closing the finding.

Keep unresolved questions open with a fallback basis and decision date. Do not turn an assumption into a confirmed fact to finish the review.

Connect the result to the estimate

Use the construction logistics estimate review for the related estimate control. Link records by identifier rather than copying unsupported conclusions.

The rental period check supports the project decision. It does not replace the approval authority assigned to the estimate.

Use a repeatable review sequence

Test a typical rental item, an exception, and a condition with a material effect on the estimate. Record why each sample was chosen. Trace equipment item through billing unit, mobilization date, active and standby time, and return date.

Stop where the evidence and estimate treatment diverge. After a correction, recheck dependent subtotals, markups, alternates, and reported totals. Close the item only when the reviewed release contains the result.

Prepare the handoff

Give the receiving reviewer the active record, source references, closed findings, open actions, and exact estimate version. The person should be able to reproduce the treatment without searching email. Confirm that every material rental item has a source, named owner, current treatment, and closure status.

Frequently Asked Questions

Who owns the rental period check?

The equipment estimator maintains the working record. The project role assigned to approve material scope or cost changes retains final authority.

When should the rental period check be performed?

Perform it when the source enters the estimate and again when the source, scope, calculation, or release changes.

What belongs in the handoff?

Retain the source, working record, checked calculation, disposition, open actions, and exact estimate version that contains the result.
