What Pro Gives You

💾 Save & Load Calculations

Never redo a calculation because you closed a tab. Save any calculation to a project, reload it later, and create new revisions as your design evolves.

📄 Branded PDF Reports

Generate clean, professional calculation reports with your name, project info, and code references. No watermarks. Ready for submittals and peer review.

⚡ Batch Mode

Run entire stressing schedules, multiple load cases, or parameter sweeps at once. Available now for PT Elongation, expanding to more tools.

📖 Code Reference Popups

Every result links directly to the governing code clause (ACI, AISC, PTI). Click any code reference to see the relevant section and commentary.

📊 Parameter Comparison

Run side-by-side “what-if” scenarios. Change one variable and instantly see how it affects every result. Essential for design optimization.

🔗 Shareable Links

Generate a public read-only link to any calculation. Share with colleagues, clients, or reviewers — they don’t need an account to view it.

Firm Features

👥 Team Workspace

4 engineer seats included. Everyone shares projects and calculations. Add more seats at $25/month each.

🏷️ Company Branding

Your firm name, logo, and PE stamp on every PDF report. Professional output your clients expect.

📐 BIM/IFC Export (Coming Soon)

From calculation to 3D model. Generate standards-compliant IFC files directly from your calculator inputs. Your PT tendon drape profile, base plate geometry, or column design — exported as a BIM model ready for coordination in Revit, Tekla, or any IFC-compatible platform.

No manual modeling. No third-party plugins. Your engineering data is already structured — we just give it a third dimension.

🏗️ Engineering Calculators

Every calculator is built to ACI 318, AISC 360, and PTI standards by licensed Professional Engineers. Not simplified approximations — real engineering with code references on every output.

Base Plate & Anchor Bolt Design — AISC Design Guide 1, ACI 318 anchor provisions
PT Tendon Elongation & Losses — PTI/ACI method with batch mode for full stressing schedules
Punching Shear & Stud Rail Designer — ACI 318-19 two-way shear with Decon stud rail sizing
Reinforced Concrete (RC) Column Interaction Diagram — Full P-M interaction with biaxial bending
Beam Calculator — Steel & concrete with AISC/ACI code checks
Torque & Bolt Design — SAE and metric with preload verification
15+ more — Foundations, unit conversions, material properties, wire gauge, hydraulics
