Gravel stockpile calculator4/9/2023 With the appropriate drone mapping software, construction companies have fast and reliable access to cut and fill calculations, historical volume comparisons, and more. This level of accuracy is accomplished through a variety of drone surveying and mapping methods, such as GCPs, photogrammetry, and LiDAR. Drone data is incredibly accurate, with an accuracy of 1/10ft (3cm) for stockpile measurements. Measurements such as volume, density, and tonnage can be precisely calculated using drone mapping software. This can be extremely useful when dealing with erodable material that needs to be audited frequently. It becomes much easier to conduct frequent surveys with a drone, enabling monthly instead of quarterly or annual inventory counts. Additionally, more frequent data collection can keep inventory counts up-to-date.Ĭonstruction companies can collect stockpile measurements as often as they want to fly the drone. Having accurate measurements can reduce overestimated material and supply orders, cutting back on waste and unnecessary spending. With cloud-based drone software, the calculations can be accessed in the field on an iPad for a quick turn-around time. You can specify a reference level and the type of material in most software settings. Once the drone data is uploaded and processed, the software automatically calculates the volume and provides additional tools to calculate tonnage, cost, and other metrics about the stockpiles. Then stand by and let the drone collect the data.įrom there, all that’s left to do is upload the data into a software that can turn it into a 3-D model, like the Propeller Platform (this is one example of many drone mapping software options). The drone can determine its own flight path-all that’s required is for the remote pilot to input a few variables about the area being flown like GPS data or ground control points (GCP method). The process for using a drone to measure stockpiles begins with flying the drone to capture aerial images. A drone only needs a few minutes to complete a job that would otherwise take hours using manual tools. This method was still time-consuming and lacked precision.ĭrones catapulted stockpile measurement tools to a new level of technological advancement. Depending on how much material was being assessed, the measuring process could take hours or days with these manual tools.Ĭell phone apps sped up the process somewhat they required the worker to mark reference points with cones and then walk around the pile on foot while pointing the cell phone camera at the pile. An electronic distance meter and laser scanner were considered to be the more technologically advanced tools for stockpile measuring. Until recently, the technology used to calculate the data had not progressed much, with simple tools such as measuring tape and plumb bobs in use for the longest. 6.Traditional stockpile measurements required getting up close with the materials to assess their quantity, cost, or weight.6.72 Vegetative Streambank Stabilization.6.52 Block and Gravel Inlet Protection (Temporary).6.51 Hardware Cloth and Gravel Inlet Protection (Temporary).6.50 Excavated Drop Inlet Protection (Temporary).6.23 Right-of-Way Diversions (Water Bars).6.22 Diversion Dike (Perimeter Protection). 6.17 Rolled Erosion Controlled Products.6.13 Trees, Shrubs, Vines, and Ground Covers.6.06 Temporary Gravel Construction Entrance/Exit.These revisions can be printed and inserted into your physical copy to update it to the current version.Ģ013 Design Manual Updates (revisions only)Įrrata-June 2006 Revision Packet NC Erosion and Sediment Control Planning and Design ManualĬhapter 1 - North Carolina Sedimentation and Control LawĬhapter 2 - Processes and Principles of Erosion and SedimentationĬhapter 4 - Preparing the Erosion and Sedimentation Control PlanĬhapter 5 - Overview of Erosion and Sedimentation Control Practices These revisions are incorporated into the current version of the NC E&SC Planning and Design Manual but are provided separately here for the convenience of those that have a physical version of the E&SC Planning and Design Manual. This section contains recent revisions and notices about the revisions. This manual was first published in 1988, with revisions in 1993, 1997, 2006, 20.Ī Field Manual and Inspector’s Guide are also available on the DEMLR Publication’s page. Therefore, sections of the manual may change as practices for erosion and sedimentation control evolve. This manual is intended for periodic updates. The practice standards and specifications are guidelines, intended to minimize the time required to design practices for use under typical site conditions. This manual contains tools and information for developing plans to minimize soil erosion and prevent sedimentation associated with land-disturbing activities.
