Audit equipment rates in change orders: hours, ownership and overlap

Identify the equipment and rate method

Record the asset or rental reference, equipment class, capacity, location and work period. Obtain the agreement's rate rule and any approved schedule. Determine whether the charge uses an actual rental cost, an owned-equipment rate, a negotiated hourly amount or another basis.

Avoid substituting a published rate book for the governing agreement without authorization. An asset's market rental rate can support a reasonableness question but may not establish the payable amount. Keep the rate source and effective date visible, including any approved cap, minimum or utilization condition.

Reconcile the time to the changed work

Compare daily equipment records, field tickets, rental periods and the change's work dates. Identify productive time, authorized standby and periods assigned to other work. A rental period is evidence that equipment was available, not necessarily that every hour is allocable to one change.

For equipment shared among base scope and changes, preserve a source-backed allocation. Check for overlapping billing windows across change requests and separate equipment-cost lines. A screening overlap is not proof of excess: the agreement may permit concurrent rate components or a minimum charge. Ask the designated reviewer to decide against the actual rule.

Worked example: fuel already included in the rate

Assume a fictional change allows 24 verified hours at $150 per hour, with fuel included and the operator excluded. The equipment amount is $3,600. The request adds a separate $400 fuel charge and $1,200 for the operator.

Under those assumptions, equipment plus the separately eligible operator totals $4,800, compared with the submitted $5,200. The potential repeated fuel charge is $400. Verify operator hours and pricing independently. If the agreement excludes fuel from the equipment rate, the extra $400 may be legitimate. The example is an original calculation, not a published equipment schedule.

Check daily, weekly and monthly treatment where relevant

When the agreement reimburses actual rental cost, reconcile the vendor invoice, rental amendments, returns and credits. Review the billed rate period and any agreed conversion to a longer-term rate. Do not assume that paying a daily amount for several days always entitles the owner to a weekly price; inspect the actual rental and prime-contract terms.

Keep damage, delivery, pickup and environmental fees as separate components. Determine whether each is eligible for this change and already included in another cost or fee. Use the rental-invoice guide for vendor-level reconciliation; this procedure addresses the additional allocation and entitlement questions inside a change request.

Give the reviewer the rate, period and competing record

An equipment finding should identify the asset, time window, contractual basis, requested amount and proposed treatment. Attach the conflicting record and ask a precise question. Preserve valid explanations and clean items rather than publishing a list that only counts allegations.

For Buildalytic, scope the collection of missing equipment records and response follow-up around the system of record. Any rate reconciliation or asset-level matching should have an agreed scope and independent acceptance test. Include a clean rental, a legitimate standby case and a repeated-component example. The trial should prove review quality across all three, not merely produce a low price.
