Why hired equipment needs tracking
Hired equipment is one of the largest variable costs on a construction project. A mid-sized civil project might spend $50,000 to $200,000 per month on hired plant, and that cost accumulates every day whether the equipment works or sits idle. Despite this, most construction companies track hired equipment less rigorously than they track their own assets. The logic seems to be: it is not ours, so it is not our problem. That logic is expensive.
The problems that arise from poor hired equipment tracking are predictable and costly. Equipment stays on site after its task is complete because nobody triggered the off-hire. Invoices arrive for items that the project team cannot verify were actually on site for the billed period. Compliance documentation is assumed to be the hire company's responsibility, but the construction company is liable if non-compliant equipment operates on their site. Utilisation data is not captured, so there is no evidence to support off-hiring underused equipment.
Australian construction companies report that 8 to 15 percent of their hire spend is wasted on idle or over-hired equipment. On a $2 million annual hire spend, that is $160,000 to $300,000 in recoverable cost. The tracking system that prevents this waste pays for itself many times over.
From a compliance perspective, the person conducting a business or undertaking (PCBU) is responsible for ensuring that all equipment on their site, whether owned, leased, or hired, is safe and compliant. A hired crane with an expired annual inspection certificate is the construction company's compliance failure, not the hire company's. Tracking hired equipment with the same rigour as owned equipment through your compliance system closes this gap.
Building a hire register
A hire register is a structured record of every piece of hired equipment currently on hire or recently returned. It should be part of your broader asset register but clearly distinguished from owned assets. The register provides the data needed for cost control, compliance verification, and invoice reconciliation.
For each hired item, record the hire company and contact details, hire agreement or purchase order number, description and specifications of the equipment, serial number or fleet number (from the hire company), hire start date, expected hire end date, daily or weekly hire rate, any additional charges (delivery, pick-up, damage waiver, insurance), current site location, and the project and cost code the hire is charged to.
Add compliance data to the register. Record the registration status and expiry (for registered plant), the last inspection certificate date and next due date, and any conditions or restrictions on use. This data should be verified at on-hire, when the equipment first arrives on site, and monitored throughout the hire period. If a compliance date falls due during the hire, the hire company is responsible for arranging the inspection, but you are responsible for verifying it happens.
Maintain the register in the same system as your owned assets. This gives the site team a single view of all equipment on site, regardless of ownership. When the site foreman needs to know what is on site, they should not need to check two systems. Integrating hired equipment into your asset tracking platform provides this unified view.
Update the register in real time. When equipment arrives on site, add it. When it leaves, mark it as off-hire with the return date. When it moves between sites, update the location. Real-time updates prevent the common problem of hiring the same equipment type for two sites when one of those sites already has an idle machine from a previous hire that nobody remembered to off-hire.
Controlling hire costs
Hire cost control starts before the equipment arrives on site. The hire rate is negotiable, and the negotiation leverage depends on lead time, volume, and relationship. Booking four weeks ahead at the start of a six-month project is very different from emergency hiring on a Friday afternoon.
Negotiate rates based on hire duration. Most hire companies offer tiered pricing: a daily rate for short-term hires, a reduced weekly rate, and a further reduced monthly rate for long-term hires. For equipment needed for more than four weeks, the monthly rate can be 20 to 40 percent lower than the daily rate. Lock in the long-term rate at the start of the hire, even if the exact duration is uncertain.
Volume discounts apply when hiring multiple items from the same supplier. If you need three excavators, two rollers, and a generator for the same project, negotiate a package rate rather than hiring each item individually. Some hire companies offer project-based pricing where all equipment for a project is bundled under a single agreement with a blended discount.
The biggest cost control lever is utilisation monitoring. Track the operating hours of every hired item daily. Calculate utilisation as operating hours divided by available hours. Set a minimum utilisation threshold. For daily-rate hires, any item below 50 percent utilisation for a full week should be reviewed for off-hire. The decision to keep or return should be based on the forward programme: will it be needed next week? If not, off-hire today and re-hire later if needed. The re-mobilisation cost is almost always less than a week of idle hire.
Damage waiver and excess provisions in hire agreements deserve attention. Most hire companies offer a damage waiver for 10 to 15 percent of the hire rate that limits the hirer's liability for accidental damage. For high-value equipment and rough construction environments, this is usually worthwhile. Check whether your company's insurance covers hired equipment, as this may duplicate the damage waiver. Read the hire terms carefully, some agreements exclude certain types of damage (such as undercarriage wear on tracked machines) from the waiver coverage.
Compliance for hired equipment
Compliance verification for hired equipment is a shared responsibility between the hire company and the hirer. The hire company must provide equipment that meets regulatory requirements and supply current compliance documentation. The hirer must verify that documentation is current, refuse equipment that does not comply, and monitor compliance throughout the hire period.
At on-hire, before the equipment starts work, verify the following: registration is current (for registered plant such as cranes and elevated work platforms), the annual inspection certificate is current and covers the expected hire period, all safety features are functional (emergency stops, ROPS/FOPS, alarms, lights), the operator manual is present, and the machine hours or odometer reading is recorded for both condition documentation and maintenance scheduling purposes.
Take photos of the equipment at on-hire. Document the condition of the body, tracks or tyres, glass, and any existing damage. This protects against false damage claims at off-hire. Include close-up photos of any pre-existing damage with a note that it was present at the time of delivery. Store these photos in the hire record alongside the compliance documentation.
During the hire, treat compliance the same as for owned equipment. Daily pre-start inspections by the operator, scheduled maintenance according to the hire agreement terms, and immediate reporting of defects to the hire company. If a compliance date falls due during the hire (such as an annual inspection or registration renewal), notify the hire company at least 30 days in advance and confirm their arrangements for the inspection. Do not allow the equipment to continue operating past a compliance expiry date.
If the hire company is slow to respond on compliance issues, escalate quickly. A conversation about a pending inspection certificate two weeks before expiry is a professional exchange. A conversation about an expired certificate while the equipment is still operating on your site is a compliance crisis. Your plant compliance processes should cover hired equipment with the same alert schedules as owned items.
Off-hire and return processes
The off-hire process is where most hire cost overruns occur. Equipment that is no longer needed but has not been formally off-hired continues to accrue charges. The site team assumes someone else has arranged the return. The fleet team assumes the site still needs it. The hire company continues billing. This gap costs construction companies thousands of dollars per month.
Build a formal off-hire trigger into the project programme. When the activity that requires the equipment completes, the system generates an off-hire notification. The site foreman confirms the equipment is no longer needed, the fleet manager issues the off-hire to the hire company, and the collection is scheduled. This process should be as structured as the on-hire process, not left to informal communication.
Provide written off-hire notification to the hire company. A phone call is a start, but it does not create an auditable record. Send the off-hire via email or through the hire company's portal with the off-hire date, the equipment description, and the collection arrangements. Retain a copy in the hire record. This documentation is essential for invoice reconciliation: if the hire company bills beyond the off-hire date, you have evidence of when the notification was provided.
Inspect the equipment at off-hire and document its condition. Compare the condition to the on-hire photos. Note any damage that occurred during the hire, distinguishing between fair wear and tear (which is the hire company's cost) and damage caused by misuse (which is the hirer's cost). Fair wear and tear includes normal track or tyre wear, paint scratches from general operation, and minor surface marks. Damage includes broken glass, bent structures, hydraulic leaks from impact damage, and bucket or attachment damage beyond normal wear.
Record the machine hours or odometer reading at off-hire. The difference between the on-hire and off-hire readings provides the total hours or kilometres operated during the hire, which is useful for cost-per-hour analysis and for resolving any disputes about operating hours. Clean the equipment before return. Most hire agreements require the equipment to be returned in a clean condition, and cleaning charges from hire companies are typically higher than doing it yourself.
Invoice reconciliation
Hire invoice reconciliation is the final control that catches billing errors, overcharges, and disputes. Without reconciliation, you are paying whatever the hire company bills, and experience shows that hire invoices frequently contain errors that favour the hire company. This is not malice; it is the result of complex billing systems, multiple rate structures, and high transaction volumes.
Match every invoice line item against the hire register. Verify the hire period billed matches the on-hire and off-hire dates in your records. If the invoice bills for 45 days but your records show 38 days, query the difference. Verify the rate matches the hire agreement. If the agreement specifies $650 per day for a monthly rate and the invoice shows $750 per day, it may have reverted to the short-term rate.
Check for charges that were not agreed. Common unexpected charges include environmental levies, fuel charges for equipment returned with less fuel than supplied, cleaning charges, inspection or service charges during the hire, and transport charges at rates higher than quoted. Some of these may be legitimate and covered by the hire terms. Others may be billing errors or charges that should be negotiated at the hire agreement stage.
Dispute errors promptly. Most hire companies have a dispute resolution process with a time limit for raising queries, typically 14 to 30 days from invoice date. Beyond this window, the invoice is assumed accepted. If your accounts payable team processes hire invoices without project team verification, errors pass through undetected. Implement a two-step approval process where the site or project team verifies the invoice accuracy before accounts payable releases payment.
Analyse hire costs at the project level and across the business. Which projects are the heaviest hire consumers? Which equipment types are hired most frequently? Are there items that are hired so often that purchase would be more cost-effective? What is the average utilisation of hired equipment versus owned? This analysis, drawn from the hire register and reconciled invoice data, informs fleet strategy decisions about what to own, what to hire, and how to optimise the split. Feed this data into your asset register and fleet management processes for a complete picture of your equipment costs.
