How Aerial Surveys with Drones Save Companies Money: A Real World Look
Drones in Mining and Aggregates, Part Two
In Part 1 of this series, we took a step-by-step look at our process of measuring stockpiles through aerial surveys in mining, aggregates and construction. The process itself is quick and efficient, particularly in comparison with traditional quantifying methods (i.e. “walking the piles”).
Whether a company decides to invest in its own drone package for recurring aerial surveys, or hires a qualified service provider to come out periodically (Diverse Flight Solutions does both in the state of Florida), this technology is saving mining and aggregate firms a great deal of money, time, as well as liability.
Now that you’ve seen the calculation process, let’s take a look at one company’s in-depth economic study comparing stockpile measurement done through conventional methods versus aerial surveys through drone technology.
Aerial Surveys Provide Substantial Savings for Alabama Contracting Company
This study, provided by Kespry, begins by adding up the company’s costs associated with quantifying stockpiles at three sites—each with a total of 30 large piles—over the course of a year. Costs were broken down into three categories as follows:
Annual Costs (Without Drone)
Manpower – Before incorporating aerial surveys, the company conducted four internal volumetric measurements over the course of the year. Each of the three sites took a week to quantify, which translated to a total of 576 hours at $30/hr for an annual total of $17,280 of employee manpower.
Equipment – The cost of the survey and GPS equipment was figured by the firm’s finance department to be $11/hr, adding up to $4,752 over the course of the year.
Third Party Expenses – Two external ground surveys were completed throughout the year as well. One was carried out via manned aircraft at a cost of $11,000 and another by ground at $4,800, for a third party total of $15,800.
Total Annual Cost: $37,832
