Read full description

Benchmark Slope is a new application that helps any of your employees determine jobsite elevation marks quickly and accurately. When provided with the intended elevations, Benchmark Slope instantly provides target pole-shots based on your established instrument height. After setting up their Instrument, the user is prompted to first enter the Jobsite Benchmark Elevation, followed by the initial reading on their Graduated Pole at the benchmark. With these two pieces of information, the application calculates the Height of Instrument and opens an interface which allows the user to input various elevation points. With each elevation entered, the application instantly provides the desired Target Pole Shot at that given point. The application also features a Slope Calculation Function that allows users to quickly and accurately calculate difference in elevation, distance apart, and gradient between any two elevation points. The feature allows the user to instantly determine grade-range compliance, pitch, and grade. A Quick toggle allows the user to view rise or fall. Previously a tedious and error-prone process, Benchmark brings speed and accuracy to establishing jobsite elevations and slopes. With this application, virtually any user can quickly determine accurate elevation points in any desired unit of measurement, AND Quick toggles allow users to change desired units of measurement with a mere touch of the button, offering instant conversion between Decimal Feet, Feet and Inches (Imperial), and Meters Conceived and designed by and for contractors like you, Benchmark Slope saves you time and money, expands the skill set of your employee teams, and reduces costly site errors or mistakes— Subscription Information Benchmark Slope requires an auto-renewable subscription to access all features.
