LOADOUT TRANSPORTATION To learn more go to stockpile reports.com or call 425-285-4303. Collect Stockpile Data – There is only a small amount of required equipment to col‐ lect data: Two orange traffic cones; a 25‐ft. measuring tape or nylon rope; and an Apple iPhone 4S or iPhone 5 with the Stockpiles application installed (see photos page 36). View Results Online – When the stockpile reports are complete, registered users may login and access the results. Typical pro‐ cessing times vary from a few minutes to a few hours. The results contain two types of reports: Stockpile and Site. "You won't need special equipment such as LiDAR or GPS; advanced training; or an in‐ ternet connection," Kovak‐Lewis said. "It's all right there on your phone." "A Stockpile Report contains both categori‐ cal and calculated data, most importantly, tonnage and volume (cu. yd.) It includes an image of the stockpile and a topographical map," Kovak‐Lewis said. To take a measurement, producers first po‐ sition the traffic cones 25‐ft. apart in front of the stockpile to create a frame of refer‐ ence for distance. They then start the Stock‐ piles app and select the stockpile product. Next, they begin recording in video mode while walking the perimeter of the stock‐ pile, keeping the base (toe) and top in view. They finish by stopping the recording of im‐ agery after completing one trip around the stockpile, plus a few feet of overlap. Sync Data – There are currently three ways to synchronize (synch) the Stockpiles app data with Stockpile Reports: 1. Wi‐Fi network. 2. Cellular network, preferably LTE. 3. USB cable to a laptop or desktop computer with an Internet connection. "The memory capacity of the iPhone deter‐ mines how frequently to synch the data with Stockpile Reports," Kovak‐Lewis said. "An iPhone 4S or iPhone 5 with 16GB ca‐ pacity typically holds the data for 50‐60 stockpiles." In the event of battery failure, the Stock‐ piles app safely stores the unsynched data. After power is restored, the data can be synched without loss. A Site Report collects the Stockpile Reports for a site and overlays them on a Google Maps view. The purple‐shaded areas repre‐ sent stockpile data collected using an iPhone. Green‐shaded areas represent stockpile data collected using GPS. Clicking on a stockpile reveals information about the pile, including: the pile name, material, ton‐ nage and volume. The Benefits According to Bill Gibson, production equip‐ ment manager for Knife River, the Stockpile Reports system has great potential to be‐ come an integral part of the company's reg‐ ular production procedures. "This is a great concept," Gibson said. "It has a lot of potential. Any time you are not climbing on the stockpiles, it is a plus." Gibson said that the company used other types of measurement systems in the past, however this one is safer and quicker. "It used to take three or four hours to walk the piles and get the information we needed," he said. "We had to import data into AutoCAD to create stockpile models and calculate volumes. Using the Stockpile Report system, maybe two hours total and we are done." Who Benefits? Who should manage their aggregates inventories online using Stockpile Reports? The benefits cut across the entire company. ■ Quarry managers and plant supervisors who want to optimize the profit performance of their mining, quarrying and rock crushing operations. ■ CFOs who want to increase inventory turns of construction aggregates while decreasing operating expenses. ■ Construction aggregates sales managers who want to sell every ton of inventory while decreasing stock-outs. 38 ROCKproducts • JUNE 2013 www.rockproducts.com
