4.3.2. Factors Affecting Repair Costs

Operating costs occur only when the equipment is used. They are highly variable and depend on the usage of the equipment, as opposed to fixed ownership costs.

Operating costs are the expenses incurred while using equipment. Unlike ownership costs, which are fixed and incurred regardless of whether the equipment is used (like insurance or loan payments), operating costs fluctuate based on how often and in what conditions the equipment is utilized. This means that the more you use a piece of equipment, the higher the operating cost will be due to factors like fuel consumption and wear and tear.

Imagine a car being parked in your garage versus one that is frequently driven. The costs associated with the parked car (insurance and registration) are like ownership costs. However, the gas you buy and maintenance you do as you drive the car are operating costs, which increase with more trips.

The components of operating costs include consumables (fuel, oil, filters), wages for operators, and maintenance and repair costs. Minor repairs fall under operating costs, whereas major repairs are considered ownership costs.

Operating costs consist of various components. Consumables are the essential supplies used during operation, such as fuel and oil. The wages paid to operators also contribute to operating costs. Maintenance and repairs are split into minor and major categories: minor repairs are regular upkeep that maintains operational efficiency (like fixing lights), counted as operating costs. Major repairs are more significant failures (like replacing a whole engine), which are classified as ownership costs since they involve more extensive investment.

Think of running a coffee shop. Ingredients and wages for baristas are like consumables and wages in operating costs. If a coffee machine minorly breaks and needs a simple fix, that’s an operating cost. If it completely breaks down and needs to be replaced, that’s akin to a major repair falling under ownership costs.

Operating costs vary significantly with the nature of the job and the conditions in which the equipment is used. Heavy and unfavorable working conditions lead to higher operating costs.

The operating costs of equipment can vary dramatically depending on its working conditions. For example, if an excavator is used in a quarry where the terrain is tough and rough, it will have higher fuel and repair costs compared to working in a typical construction site with softer soil. The wear and tear on the equipment will be greater in challenging conditions, leading to increased costs associated with repairs and maintenance.

Consider a person jogging in a park versus running on a rocky mountain trail. The park is flat and easy, resulting in less wear on shoes and lower effort. The mountain trail, however, requires more energy and results in quicker wear on shoes, similar to how equipment fares differently in various work environments.

To estimate operating costs accurately, past experience records and manufacturer guidelines should be utilized. These provide data on expected fuel costs, lubricants, and maintenance expenses.

Understanding and estimating operating costs effectively require looking at historical data from previous projects or similar equipment use. Contractors might keep detailed records of how much fuel certain equipment uses under specific conditions. Additionally, manufacturers provide handbooks that outline expected performance, including fuel consumption and repair costs for their equipment under varying conditions. This information can be crucial when planning for equipment costs in new projects.

Just like a student studying for an exam would benefit from reviewing past tests and quizzes to understand what types of questions to expect, contractors use past performance data and manufacturer resources to predict and prepare for future equipment operating costs.
