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
