Today we’re discussing Ownership Costs, a vital aspect of construction management. Ownership costs include depreciation, taxes, and insurance. Can anyone tell me what depreciation is?
Isn't depreciation the reduction in value of the equipment over time?
Exactly! And how do we calculate it?
By subtracting the salvage value from the initial cost and dividing that by the machine's useful life!
Great job! Remember, depreciation helps us understand how much value the equipment loses, which factors into our total cost of ownership.
Calculating Operating Costs

Now let’s move on to operating costs. What do you think fuel cost encompasses?
Fuel costs would be based on the equipment's fuel consumption and the cost per unit of fuel.
Exactly! If a machine consumes fuel at a rate of 5 gallons per hour, and fuel costs $3 per gallon, what's the hourly fuel cost?
$15 per hour.
Right! Always keep in mind the load conditions as they can affect fuel consumption.
Caterpillar and Peurifoy Methods

Let’s discuss the Caterpillar and Peurifoy methods for estimating equipment costs. What’s unique about these methods?
I think they both offer systematic approaches for calculating costs, right?
Correct! Caterpillar focuses on depreciation and operating costs, while Peurifoy introduces the time value of money for a more precise estimation.
So Peurifoy's method may be more accurate because it considers the timing of cash flows?
Absolutely! Remember, its key components include using the Uniform Series Capital Recovery Factor.

Quick Overview
Standard
This section outlines the concepts of ownership and operating costs in construction equipment management. It covers the Caterpillar and Peurifoy methods for cost estimation, detailing the calculation of depreciation, fuel cost, consumables, and operating wages to provide a comprehensive understanding of total equipment costs.
Detailed
Detailed Summary
The section on Ownership Cost explores the core components involved in estimating total equipment costs in construction management, especially utilizing the Caterpillar and Peurifoy methods. The lecture first revisits the concept of ownership cost before providing a stepwise approach to estimating costs associated with equipment, focusing on:
- Depreciation Calculation: Using the straight line method as a primary approach, the lecture details how to calculate depreciation by taking the initial price of the equipment, deducting the salvage value and tire cost, and dividing by the useful life to arrive at hourly costs.
- Components of Ownership Cost: Other ownership costs such as the cost of investment, taxes, and insurance are discussed, illustrating how these factors are expressed as a percentage of the machine's average value.
- Operating Costs: The lecture extensively details operating costs, particularly fuel costs and consumables like filters and lubricants. Both the Caterpillar Performance Handbook and manufacturer guidelines are referenced as sources of information to obtain fuel consumption factors.
- Final Integration: The section concludes with a synthesis of ownership and operating cost components, emphasizing the importance of accurate record-keeping and manufacturer resources for achieving accurate costs estimation.

Chapter Content
Ownership cost is one of the two main components involved in estimating the total equipment cost, along with operating cost.
Detailed Explanation
Ownership costs include all expenses associated with owning equipment over its lifecycle. This includes depreciation, insurance, taxes, and costs related to investment. Properly estimating ownership cost is crucial as it helps in setting a realistic budget and ensures that all costs associated with the equipment are accounted for.
Examples & Analogies
Think of ownership cost like the expenses related to owning a car. Apart from the purchase price, you have to consider insurance premiums, taxes, and depreciation as the value of the car goes down over time.
Depreciation Calculation

Chapter Content
The first step in estimating the ownership cost is calculating depreciation using the straight-line method:
Depreciation = (Initial Price - Salvage Value - Tire Cost) / Depreciation Period in Hours
Detailed Explanation
The depreciation calculation reflects how much value the equipment loses over time due to wear and tear. By using the straight-line method, the cost of the equipment is spread evenly over its useful life. This method is straightforward: subtract the salvage value (what you expect to sell the equipment for at the end of its useful life) and the tire cost from the initial price, and divide that by the total number of hours the equipment is expected to be operated.
Examples & Analogies
Imagine you buy a new laptop for $1,000 that you expect to use for 5 years with a salvage value of $200 at the end. Your annual depreciation would be: ($1,000 - $200) / 5 = $160 per year, representing the decrease in its value each year.
Average Value of Equipment

Chapter Content
The average value of the machine during its lifecycle can be calculated using the formula:
Average Annual Investment = (P(n+1) + S(n-1)) / (2n)
Detailed Explanation
To accurately estimate other ownership costs, it's essential to understand the average value of the equipment throughout its useful life. This average helps apply costs such as taxes and insurance more accurately since these expenses often depend on the estimated value of the equipment rather than its original price.
Examples & Analogies
Consider a smartphone that you bought for $800 with an expected salvage value of $100 after two years. The average value of the smartphone over its lifecycle would help you discern costs such as insurance that would be lower as the device depreciates.
Additional Ownership Cost Components

Chapter Content
Other ownership cost components include:
1. Cost of Investment
2. Taxes
3. Insurance
Detailed Explanation
After calculating depreciation and the average value of the equipment, you need to factor in other costs like taxes and insurance. These costs are usually calculated as a percentage of the average or initial cost of the equipment. By knowing these percentages, you can compute the total ownership costs accurately. These components can often significantly impact the overall budget for the equipment.
Examples & Analogies
If you own a home, you not only consider the mortgage payment (initial investment) but also ongoing expenses such as property taxes and homeowner's insurance, which contribute to the overall cost of owning that home.
Moving to Operating Costs

Chapter Content
Once ownership costs are determined, the focus shifts to operating costs which cover consumables like fuel, maintenance, and labor.
Detailed Explanation
Operating costs are ongoing expenses required to keep equipment running efficiently. This includes fuels and lubricants, maintenance, and wages for operators. Understanding these costs is vital for a complete picture of the overall cost of asset ownership and operation, impacting budgeting and financial forecasts.
Examples & Analogies
Much like owning a car, you will incur regular costs like fuel, oil changes, and tire replacements. Owning a car isn't just about the purchase price; it's also about what it costs to keep it on the road.
Key Concepts
-
Depreciation: Calculating the reduction in equipment value over time.
-
Caterpillar Method: A systematic way of estimating ownership and operational costs.
-
Peurifoy Method: Incorporates time value of money for accurate cost estimation.
Examples & Applications
If an excavator costs $100,000 and has a salvage value of $10,000 with a useful life of 5,000 hours, the hourly depreciation would be ($100,000 - $10,000) / 5000 = $18/hour.
For fuel costs: if a machine uses 4 gallons per hour and fuel costs $2 per gallon, the fuel cost per hour is 4 * $2 = $8.
