Civil calcs that hold up in review
Tributary loads, beam checks and hydrostatic forces in one worksheet, with assumptions written down next to the numbers they affect and every unit checked by the engine.
Assumptions on the record
Assumptions live in a ledger next to the calculation, where a reviewer sees them with the numbers they affect.

What you can calculate
- ✓Load takedown and tributary areas
- ✓Beam reactions, moments and bending checks
- ✓Hydrostatic forces on gates and walls
- ✓Centroids and moments of inertia of sections
- ✓Heat loss through building assemblies
- ✓Unit-aware solving for any unknown
Worked examples
Simply supported beam: reactions, maximum moment and bending stress
R_A = 56 kN, R_B = 46 kN, M_max = 88.17 kN·m at 2.17 m from A, and σ_max = 161.2 MPa < 207 MPa: the W310×39 is adequate in bending.
Hydrostatic force on a vertical gate
F_R = 88.29 kN, acting 1 m above the bottom of the gate (2 m below the surface).
Heat loss by conduction through a plane wall
The wall loses 1800 W, and its thermal resistance is 0.0139 K/W.

AI-native, never required
The assistant drafts on the same worksheet you work on. You can do everything without it, and it never does the math: the engine does, with units, and checks it.
