Own, Hire, or Lease?
Equipment decisions are among the most capital-intensive choices a construction business makes. Buy the wrong gear, and you’re paying for depreciation and maintenance on equipment that sits idle between projects. Rely too heavily on hire, and your margins disappear whenever you need specialist plant. Getting the own/hire/lease equation right is a core business strategy question for civil, excavation, and construction businesses of all sizes.
The starting point for any equipment strategy is a rigorous analysis of utilisation. Equipment you own needs to be working enough hours to justify its ownership cost. A rule of thumb is that if you can project 60–70% utilisation of a machine over a 12-month period, ownership generally beats hiring. Below that threshold — or when there’s significant uncertainty about future work — hire provides flexibility that ownership doesn’t.
Depreciation: The Silent Cost
Depreciation is the cost of using an asset — the progressive decline in its value as it ages and accumulates hours. Many small construction businesses underestimate depreciation as a cost because it doesn’t appear as a cash outflow in the same way that a hire invoice does. But depreciation is real: the excavator you buy for $250,000 today will be worth significantly less in five years, and that difference is a genuine cost of doing business that needs to be recovered in your project pricing.
IRD’s depreciation rates provide a starting point, but market-based depreciation (what the machine is actually worth, given current market conditions) is the more relevant figure for business decision-making. Plant and equipment valuers can provide independent assessments of current market values that help you understand your true cost position.
Maintenance as a Strategic Asset
Well-maintained equipment is more reliable, has a higher residual value, and creates less project risk than poorly maintained plant. A regular service schedule — tied to hours of operation rather than just calendar time — and prompt attention to developing faults is cheaper than the cost of unexpected breakdowns, delays, and emergency repairs. Construction businesses that treat maintenance as an overhead to be minimised often find that false economy when a critical piece of equipment fails at the worst possible time.
