Your work as a sharable URL. Pinned designs, code certifications, contact.
Every module link opens a dedicated page with the same five-section structure. Scroll once, learn what the tool does, then run a design.
Intro to the module, supported design codes (IS, ACI, Eurocode) and what makes it different.
Four value props that explain the engineering choices — not generic feature bullets.
Four-step workflow — what to enter, what the engine does, what to inspect, how to export.
Common project scenarios (residential, industrial, retrofit) so you know if this tool fits.
People-also-ask questions answered inline, plus links to related modules in the suite.

60-second walkthrough · IntelliCascade™ foundation optimization
The only patented multi-type foundation optimization engine. Not another web calculator.
IS 456, ACI 318, Eurocode 2 — with code-specific safety factors, not generic approximations.
Sub-second optimization using WebAssembly and client-side compute. No waiting for server responses.
Everything runs in your browser. Your project data never leaves your device. No cloud, no tracking.
All design tools free forever. Pro features like detailed reports, FEM, and team collaboration available when you need them.
Real feedback from structural engineers using CivilTech Studio on live projects.
“The IntelliCascade™ optimizer found a sloped footing that saves 32% steel compared to what I would have designed manually. It tried 5 types in under a second.”
Rajesh Sharma
Senior Structural Engineer · L&T Construction
“Finally, a tool that checks whether my footing stays inside the site boundary. We had a project where 4 footings were overshooting — CivilTech caught it instantly.”
Priya Nair
Design Lead · Shapoorji Pallonji
“Switching between IS 456 and ACI 318 used to mean redoing the entire calculation. Now I change one dropdown and the entire building re-analyzes in seconds.”
Ahmed Khan
Project Manager · Dar Al-Handasah
“The FEM bearing pressure heatmap showed a stress concentration we completely missed in SAFE. The Mindlin plate element gives you real insight under the footing.”
Sneha Patil
Structural Analyst · Thornton Tomasetti

CivilTech Studio is under active development. Here's what shipped recently.
IS 13920:2016 + ACI 318-19 Ch.18 + Eurocode 8 DCH — all three seismic detailing codes fully implemented with footing checks.
Full building analysis with per-floor column grids, beam optimization, drift checks, and IS 456/ACI 318/EC2 design.
C++ Mindlin plate FEM engine with Winkler springs, tension cutoff, and 4-mode 3D visualization (pressure, deformed, settlement, moments).
Complete beam, column, and slab design for ACI 318-19 and Eurocode 2, including code-specific load combinations and safety factors.
Our patented optimization engine automatically tries pad → sloped → stepped → combined → pile, with site boundary containment check at each step.

No. All computations run entirely in your browser using client-side JavaScript and WebAssembly. Your project data never leaves your device — zero tracking, zero cookies, zero cloud storage for design data.
Pad (isolated), sloped, stepped, combined, and pile foundations — each with our patented IntelliCascade™ optimization that tries every type to find the most economical solution within your site boundary constraints.
Yes! CivilTech can parse CSI SAFE (.f2k) and STAAD Pro (.std) files to import column positions, reactions, and section properties directly into the site plan workflow.
We use a C++ Mindlin plate element engine with selective reduced integration, Winkler spring supports, and iterative tension cutoff — comparable to SAFE and PLAXIS for bearing pressure distribution under footings.
Core design tools are free forever — no sign-up required. Pro features like detailed PDF reports, advanced FEM visualization, and multi-project management are available via affordable subscription plans.
