Designed by Engineers, Built for the Field

Every tool is optimized for quick, robust, and mathematically sound calculations on-site.

🧭

Advanced Surveying

Run precise bearing conversions (azimuth to quadrant & quadrant to azimuth), traverses, and Simpson's offsets with detailed segment breakdowns.

  • Segment-by-segment subdivisions
  • Quadrant-corrected bearing formulas
  • Simpson's 1/3 and 3/8 offset analysis
📊

Contour Plot Map

Directly input coordinates or import large CSV files to generate visual elevation maps utilizing Marching Squares contouring.

  • Inverse Distance Weighting (IDW) interpolation
  • Gradient-colored isoline rendering
  • Pinch-to-zoom controls & image exports
📏

Tape & Chain Corrections

Ensure distance accuracy on any terrain. Apply standardized corrections for site-specific conditions dynamically.

  • Tension, Temperature, & Sag corrections
  • Metric & Imperial live units toggling
  • Instant exportable calculation sheets
🏗️

Structural & Quantity Estimating

Calculate brick counts, concrete volumes, column limits, and beam shear force/bending moment diagrams instantly.

  • Slab, Column, & Footing estimators
  • Asphalt and Retaining wall support
  • Beam deflection and BMD/SFD visualization

Compass Bearing Tool

Input a decimal degree azimuth (0° to 360°) to convert it instantly into quadrant bearings (e.g. S 50.00° E).

Resultant Quadrant Bearing
S 50.00° E
N E S W

Concrete Volume Calculator

Compute the volume of wet concrete required and estimated cement/sand bags for a rectangular slab.

Wet Concrete Vol
7.50 m³
Cement Needed
62.3 Bags
Sand Quantity
6.60 Ton

Tape Sag Correction

Calculate the sag correction factor when a tape/chain is suspended between supports on the field.

Sag Correction (Cs)
-0.042 m

This negative value must be subtracted from the measured length to correct for sag distortion.
