Separate equipment availability, working time and billable time

In this fictional example, the scheduled shift is ten hours. The machine spends two hours unavailable because of a recorded breakdown, three hours available but on standby while the work front is blocked, and five hours doing the defined work. These categories are mutually exclusive in this example and sum to ten hours.

Available time is eight hours: ten scheduled minus two unavailable. Working time is five hours. Standby is included in available time because the machine is available for the defined task but not working. The responsible plant and planning team should approve these definitions for the report.

Do not classify the three standby hours as a breakdown merely because no output was produced. That would direct the response to maintenance when the actual constraint belongs to the work-front plan. If the cause is unknown, retain an unclassified period with an owner instead of assigning a convenient explanation.

The shift supports three different measures. Availability is eight available hours divided by ten scheduled hours, or 80 percent. Working time as a share of scheduled time is five divided by ten, or 50 percent. Working utilisation of available time is five divided by eight, or 62.5 percent.

None is a universal industry target. A useful report states the period, asset, work definition and included time. If the denominator changes between sites, the comparison needs an explanation before it is used to make a fleet decision.

An engine-hour reading can help establish operation, but an engine may run while a machine waits. Telemetry can provide frequent observations without resolving what the activity meant. The report still needs an approved distinction between working, idling, travel, standby and other relevant categories.

Procore's Daily Log documentation illustrates equipment and productivity records. Those observations can support the time classification when linked to the correct asset, shift and activity. They do not automatically establish productive output or commercial charging.

For machines that support several fronts, record the assignment changes and relevant time. Avoid crediting the same hour to two packages because both supervisors included the asset in their daily report. Keep enough evidence to resolve overlaps without demanding precision the source records cannot support.

A hire agreement may charge scheduled days, minimum periods, operating hours or standby under defined conditions. Physical use and payment eligibility therefore need their own reconciliation. In the example, the five working hours do not establish that only five hours may be billed.

The equipment hire-bill guide explains how actual terms, notices and dated records affect the charging review. Link that commercial decision to the shift evidence, while retaining its separate owner and approval.

For owned equipment, an internal allocation rule may distribute cost differently again. Finance should define the basis and make it visible. A lower utilisation ratio does not, by itself, establish a financial saving available from returning or disposing of the machine.

The two breakdown hours go to the plant team for maintenance review. The three standby hours go to the planner and site supervisor to investigate the blocked front. They may need access, materials, preceding work or a changed sequence. Each cause leads to a different next action.

If another ready front can use the machine, review the equipment's suitability, movement requirements and task permissions through the approved process. A utilisation dashboard should propose a planning question; it should not dispatch equipment automatically because another site's percentage is higher.

Look at repeated patterns over comparable work. A single unusually quiet shift may be planned standby. Several shifts waiting on the same unresolved prerequisite may justify a planning change. Record the context so a trend does not become a judgement about an operator or crew without appropriate evidence.

A controlled shift log may be sufficient for a small fleet if time categories and review are consistent. An equipment platform helps when many assets, sites and meter feeds interact. Integration becomes valuable when it reduces duplicate entry while preserving the original observations and corrections.

Give every option the ten-hour example and require it to reproduce all three ratios. Then add a missing cause, duplicate log, meter reset and late correction. The system should retain the original cut-off view and explain any restatement. It should not silently remove unclassified hours from the denominator.

For fleet totals, aggregate the underlying hours using a common basis before calculating the ratio. An unweighted average of individual percentages can misrepresent assets with different scheduled durations. Show excluded or incomplete records so the overall figure's coverage is clear.

The value of the report is the decision it supports: repair the machine, unblock a front, verify the log or review a hire commitment. Keeping the three measures together makes those conversations more precise. The maintenance-readiness guide covers the separate evidence needed before assignment.

1. Define the shift, asset and mutually exclusive time categories with plant and planning owners.
2. Reconcile the ten-hour record and display each numerator and denominator.
3. Route breakdown, standby and unknown periods to their actual evidence owners.
4. Review deployment and charging through their own approved processes before acting on the ratios.
