Straight answers on measuring stockpiles with Stockpile Reports®: how accurate it is, what it costs, and how it compares to a manual survey. Every measurement is verified and confidence-scored.
Independently validated. In a 2015 evaluation, the Texas Dept. of Transportation ran its own tests of the app against LIDAR, GPS, and manual measurements and confirmed accuracy within plus or minus 1.5%, as reported by Engineering News-Record. Stockpile Reports has documented plus or minus 2% on large stockpiles. Every measurement is confidence-scored, so you always know how far to trust the number.
You can start free. The Personal plan measures one freestanding pile a day at no cost. Professional is $20 a month or $200 a year for unlimited measurements on one phone. Business plans for teams start at $100 a month, and organizations with 200 or more piles get custom pricing. Every paid plan includes a 7-day free trial, so you can measure before you commit. See full pricing.
A manual survey means a crew, wheel-and-tape or GPS walkovers, and often a wait for results. With SR Measure®, one person walks around the pile with a phone and gets a verified volume and tonnage in minutes, each measurement confidence-scored. It removes the safety risk of climbing piles, and because every pile is measured the same way every time, results stay consistent from person to person and site to site.
