Understanding Equipment Costs
Unlock Audio Lesson
Today, we will explore the different costs associated with owning and operating equipment like dump trucks. Can anyone tell me what types of costs we might encounter?
I think there are ownership costs and operating costs.
Great! Ownership costs include things like depreciation and interest. In contrast, operating costs could involve wages and fuel. Let's remember this with the acronym OOP: Ownership, Operating, and Personnel costs.
How do we calculate these costs?
We'll cover methodologies, starting with how to estimate these costs step by step, focusing on a dump truck example.
So the dump truck has a specific initial cost right?
Exactly! The initial cost is given as ₹3 crores, and we need to factor in tire costs as well.
In conclusion, remember OOP helps us understand the essential costs involved.
Calculating Depreciation
Unlock Audio Lesson
Let's dive into an essential aspect: depreciation. Who knows why it matters in our cost analysis?
Depreciation helps us understand the reduction in value of the equipment over time.
Right! We use the straight-line method where we take the initial cost, subtract the tire cost, and divide by useful life. How many years do we estimate the dump truck will be useful?
Twelve and a half years, based on annual usage.
Exactly! We calculate the annual depreciation as ₹23,12,000, which we can break down into an hourly cost by dividing by the number of usage hours per year.
That makes sense! It shows how much the equipment costs us per hour.
In summary, understanding depreciation allows us to budget more effectively for equipment costs.
Ownership and Operating Costs
Unlock Audio Lesson
Now that we have ownership costs, how do we calculate the total costs, including operating costs?
We need to account for fuel, maintenance, and wages.
Correct! Let's calculate an hourly operating cost. What’s our hourly equipment fuel cost?
It's ₹1462.50/hr based on the consumption rate.
Well done! We also need to add the filters, oil, grease, and tire costs to that. Can you calculate the total operating cost for the truck?
The total operating cost would be ₹3209.29/hr.
Excellent! So, the total equipment cost, adding operating and ownership costs, would be around ₹6122.29/hr. Remember to consider all elements for accurate budgeting.
Peurifoy Approach to Cost Estimation
Unlock Audio Lesson
We will now discuss the Peurifoy method for cost estimation. What do you know about it?
He set guidelines for estimating equipment costs, right?
Exactly! The Peurifoy method considers the salvage value, taking it into account for an accurate reflection of depreciation.
What percentage do we usually consider for salvage value?
Typically, it’s around 20% of the initial cost, excluding tire expenses.
And what about maintenance costs?
Maintenance costs can be estimated as a percentage of total depreciation costs, which we will include as well. Remember to apply these concepts back to our dump truck calculations!
In conclusion, understanding the Peurifoy method helps further refine our estimates for budgeting equipment costs accurately.

Key Components:
- Initial Cost of Equipment: An off-highway dump truck's initial cost is given as ₹3 crores, with specific tire costs totaling ₹11 lakhs.
- Operating Hours: The truck is expected to operate for 1600 hours annually, with a total useful life of 20,000 hours.
- Ownership Costs: Includes interest, insurance, taxes, and depreciation calculated with considerations for the truck's life and operational status.
- Annual Depreciation: Based on a straight-line method, excluding salvage values.
Methodology Examples:
- Depreciation Calculation: Initial price minus tire cost divided by useful life gives the annual depreciation.
- Total Cost Calculation: Inclusion of operating costs such as fuel, filter oil, grease, and repairs contribute to overall expenditure.
- Peurifoy Method: An alternative approach is introduced, emphasizing salvage value and maintenance based on depreciation rates.
This section serves as a pivotal guide for comprehending cost estimations for heavy machinery, enabling more accurate budgeting and financial planning for projects involving heavy equipment.

So just add up everything the ownership cost all the operating cost and operating wages also you
will get the total ownership and the operating cost following the Peurifoy guidelines. Now let us
workout from examples on how to estimate the equipment cost using these 2 methods.
Detailed Explanation
In this chunk, we start with a brief overview of how to estimate total equipment costs. The key is to add together ownership costs, operating costs, and operating wages. This approach follows Peurifoy's guidelines for equipment cost estimation, which is significant in construction engineering.
Examples & Analogies
Think of budgeting for a party. You wouldn't just consider the cost of the cake (ownership cost) — you would also add in the costs for decorations, venue, and drinks (operating costs) to get the total budget needed!
Understanding Off-Highway Trucks

So you can see this problem in this problem you can estimate the cost for the dump truck. It is off
highway truck, why we call it as off highway? This truck is not permitted on the public highways.
Detailed Explanation
Here, we clarify that we are estimating costs for an off-highway dump truck, which is designed for operation at construction sites rather than public roads. This distinction is important because it highlights the vehicle's specialized nature and operational context, which can influence cost and usage.
Examples & Analogies
Consider a specialized vehicle like a garbage truck versus a family car. The garbage truck is built for specific tasks in urban environments (much like the dump truck on construction sites), and it has associated costs different from regular vehicles because of this specialization.
Initial Costs and Tire Costs

The initial cost is given so it was purchased with the deliver price of 3 crores. The tire cost of this machine is 11 lakhs.
Detailed Explanation
In this section, we discuss specific costs associated with the dump truck, including its purchase price and the cost of its tires. The initial cost of 3 crores reflects the investment in this piece of machinery, while the tire cost is 11 lakhs, which is significant due to the truck's heavy-duty requirements.
Examples & Analogies
When you buy a car, you often don't think about just the car's price. For instance, high-performance tires for a sports car can significantly add to your total cost. Similarly, the dump truck requires specialized tires that contribute greatly to its functionality and overall cost.
Interest, Insurance, and Taxes

The other associated cost are the interest rate which is nothing but 8% insurance 2% and taxes 3%.
Detailed Explanation
This chunk outlines additional ownership costs that must be considered in the total cost calculation, including interest on investment, insurance premiums, and taxes. Each of these costs is expressed as a percentage of the ownership cost, which provides a clearer understanding of the financial obligations involved in owning the equipment.
Examples & Analogies
Think of these costs as the standard additional fees when leasing an apartment — you pay not just for rent (initial cost) but also for utilities (interest), renter's insurance (insurance), and sometimes property tax (taxes), all of which add to your total monthly expense.
Annual Usage and Operating Hours
Unlock Audio Book

The truck is expected to have annual use of 1600 hours. This will give you the useful life of a machine in years.
Detailed Explanation
We introduce the expected annual usage of the truck, which is 1600 hours. This figure is essential in estimating the machine's useful life, as we can use it to calculate depreciation and other cost metrics over the truck’s lifespan. Understanding usage helps in planning for maintenance and scheduling of operations.
Examples & Analogies
Imagine a bicycle you use for commuting. If you ride it to work for 30 minutes every day, you can estimate how long it will last based on how often you use it. The more you ride, the quicker it may wear down, just like the truck with its estimated usage hours.
Fuel and Operating Costs
