Benchmark Slope helps you and your crew determine jobsite elevations, slope and pitch quickly and accurately. Elevation calculations made easy! SET YOUR HEIGHT OF INSTRUMENT After setting up the instrument, enter the jobsite Benchmark Elevation and your rod reading at the benchmark. Benchmark Slope calculates the Height of Instrument (HOI) and locks it for that instrument location. TARGET ROD READINGS, INSTANTLY Enter each intended elevation and Benchmark Slope instantly gives the target rod reading at that point, shown in a large optic. Enter the next elevation right away; your three most recent calculations stay on screen. Apply an offset to target top of sub-grade instead of top of finished slab. SLOPE Calculate the change in elevation, the distance between two points and the slope (gradient) from any three values. Falls To / Climbs To shows the direction at a glance, and ADA Slope Guidance compares the result with common ADA slope guidelines. UNITS AND CONVERSION Work in decimal feet, feet and inches, or metres, each colour-coded. A feet-and-inches keypad with fraction keys makes field entry fast, and Convert shows all three units side by side. HANDS-FREE VOICE Tap LISTEN and speak your numbers. Speech is processed on your phone; nothing is recorded or kept. English and Spanish. LEARN AS YOU GO A guided tutorial walks first-time users through each screen, and tap-to-learn help explains every field. Previously a tedious and error-prone process, Benchmark Slope brings speed and accuracy to establishing jobsite elevations and slopes. Conceived and designed by and for contractors like you, it saves time and money, expands the skill set of your crews, and reduces costly site errors. All measurements provided by this app must be confirmed on site. ADA Slope Guidance is guidance only and does not indicate full compliance.

Pipe Slope Invert Planner

Read full description

Pipe Slope Invert Planner helps drainage installers, site utility crews, excavation contractors, landscape drainage crews, plumbers, and serious DIY users check a pipe run before trench work starts. Turn run length, start invert, target slope or end invert, station spacing, pipe waste, and bedding depth into a clear field sheet you can review before digging. Use it to: - solve from slope percent, total fall, or target end invert - generate station distance, fall, and invert elevation rows - check planned slope against a user-set minimum before layout - estimate pipe order length with waste - estimate bedding volume and rough gravel cost from trench dimensions - save pipe runs locally and share a plain-text station sheet Why people buy Pipe Slope Invert Planner: - a bad trench grade can mean rework after excavation starts - missed invert drops and short material orders can cost more than the app - station tables are faster to hand off than one-line slope math - pipe length, bedding volume, and rough cost belong in the same pickup sheet - saved runs help compare a side-yard drain, utility sleeve, or tie-in before layout - the app works offline with no account, ads, subscription, tracking, cloud sync, or live supplier pricing Important: Pipe Slope Invert Planner is a field math and material estimating aid. It does not provide engineering certification, code approval, drainage guarantees, permit advice, soil analysis, or site-specific installation approval. Always verify final layout, local requirements, product specifications, site conditions, and professional requirements before digging or installing.
