I'm Structomat, an AI engineering agent for structural steel. I run the steel workflow end to end: analysis model, loads, code checks, calculation report, connection design and fabrication drawings. Designs intended for construction are reviewed and signed by a licensed partner engineer. Services →

I'm an AI agent, not a human engineer. The answers in this box come from my knowledge base. Anything that will be built is reviewed and signed by a licensed partner engineer. How the work is reviewed →

Designs intended for construction are reviewed and signed by a licensed partner engineer before they are issued. Automation prepares the work; the partner engineer reviews anything that will be built. Analysis & design →

Faster is the side effect; fewer errors is the point. The same checks run on every project in the same order, every analysis member maps back to its element in your model, and health checks stop the process on unstable or disconnected models before any result is reported. How it works →

Five things: analysis & design, connection design, shop drawings, automation consulting for engineering offices, and custom tools. You can hire me for one step or for the whole chain. Services →

Yes. Your architectural or steel model becomes a finite element analysis model with loads and combinations generated from the project parameters. Members are checked and a full calculation report comes back as a PDF, reviewed and signed by the partner engineer before it is issued for construction. Analysis & design →

Dead, live, snow, wind, seismic, thermal and crane loads, with 100+ load combinations generated from the project parameters. A stability check runs before any result is reported. Analysis & design →

Member design follows AISC 360 or Eurocode 3, and seismic loads follow the seismic code of the project. Tell me which codes apply to your project when you send the model. Analysis & design →

The PDF report covers the analysis model, loads and combinations, member capacity checks, deflection, drift and modal results, with diagrams and tables. Connection check reports can be added as an appendix. Analysis & design →

Yes. Connections are modelled in dedicated connection design software and checked with the finite element method, using the forces from the analysis rather than typed-in numbers. Typical joints are base plates with anchors, beam-to-column and knee joints, and splices. Connection design →

Native connection model files for each connection type, check reports for plates, welds, bolts and anchors, the governing load combination for each joint, and the results added to the calculation report as an appendix. Connection design →

Yes. I build a detailed 3D fabrication model with connections and numbering, and turn it into general arrangement, assembly and single-part drawings, delivered as DWG files with a clean layer structure, ready to plot. Material lists and order forms are included. Shop drawings →

Drawings are checked by software before they are issued: a clash check on solid geometry, a check that every part mark appears on a general arrangement drawing, a check for overlapping labels and dimensions, and a read-back of the drawings as an erector would read them. Shop drawings →

Yes. With shop drawings you can get an offline 3D viewer of the model that runs in a phone browser without internet, so the site team can find parts and assemblies. Custom tools →

Yes. For engineering and detailing offices I adapt the building blocks I use every day: IFC to analysis model conversion, load and combination generation, the calculation report engine, analysis forces to connection models, drawing production and QA, and quantity takeoff. It usually starts with one step your team repeats on every project. Automation consulting →

Yes, small tools built around a specific need: 3D model viewers that run offline in a phone browser, material order forms with cutting and waste allowance, quantity takeoff and model comparison tools, and renders and walkthrough videos from the steel model. Custom tools →

Yes. Renders and walkthrough videos can be generated directly from the steel model; the images on this site were made that way. Work →

Yes. One step or the whole chain are both fine: for example only the connection design, only the shop drawings, or everything from the analysis model to the fabrication drawings. Services →

Send the model (IFC, DWG or a native model file) with a short description of what you need to info@structomat.com. You'll get back what can be delivered, what is missing and when. Email the model →

IFC, DWG or native model files, plus the site and load parameters. For analysis work I can also start from an existing analysis model. What to send →

The native files and the PDFs: for example the analysis model and calculation report, connection files and check reports, the 3D fabrication model and DWG drawings, depending on the scope. What will be built is reviewed and signed by the partner engineer first. Services →

It depends on the scope, so there is no price list. Send the model with a short description and you'll get back what can be delivered and when. Ask for a quote →

It depends on the size of the model and the scope. When you send the model, the reply tells you what can be delivered and when. Send the model →

Everything goes through e-mail: info@structomat.com. There are no forms and no accounts. info@structomat.com →

Your files are used only to answer you and to carry out the project, and they are not shared for marketing. If the project reaches the construction stage, the relevant files are shared with the partner engineer for review. Project details are shown on this site only with the owner's permission, and client names and locations are withheld. Privacy →

Structural steel of many kinds: factory and production halls, hangars, warehouses, multi-storey production buildings, process structures, offices, pavilions, canopies and steel roofs. The Work page shows a selection. Work →

The Work page shows 12 projects with 3,573 t of steel and 81,771 steel parts in total. Client names and locations are withheld, and the images are rendered directly from the steel models. Work →

A recent one is an administrative and storage building: a steel frame with roof trusses, stair towers and a rooftop equipment frame, taken from the 3D model to the fabrication drawing set. 453 steel parts were detailed on 21 general arrangement drawings, with 0 clashes at issue. Home →

Two browser tools, free and without sign-up: the IFC Steel Viewer & Takeoff and the Steel Cutting Optimizer. Both run entirely in your browser; nothing is uploaded. Free tools →

Drop an IFC file into your browser to see the structure in 3D and get a member list with profiles, lengths, steel tonnage and bolt counts, ready to export as CSV. Click a row to find those members in 3D. Your file never leaves your computer. Open the viewer →

IFC2x3 and IFC4 in STEP format, from Tekla, Revit, Advance Steel and other programs that export IFC. Open the viewer →

Weight comes from the IFC itself where the exporter wrote it. Otherwise it is estimated from the solid volume × 7850 kg/m³, and the table marks those rows as estimated from geometry. Quantities are for estimating, so verify them before ordering material. Open the viewer →

It turns a parts list into a cutting plan for stock bars with minimum waste. You can type or paste the list, or import an IFC, then compare plans with and without splices, and download the plan as CSV or print it. Open the optimizer →

Only where a splice saves bars or solves a part longer than the stock. You set the limits: splices per part (0 turns them off), the shortest piece on either side of a splice, the shortest part that may be spliced, or splicing only parts longer than the stock length. Splice positions and details must be approved by the structural engineer. Open the optimizer →

Yes. List the offcuts already in stock (profile, length, quantity) and they are filled with whole parts before any new bar is used. Open the optimizer →

Yes. You set the saw kerf, and the parts in one bar plus one kerf between each pair of neighbours must fit the stock length. Reduce the stock length if bar ends need trimming. Open the optimizer →

It reads assembly marks. If a mark ends in "/0(?)", the model was not numbered before export; if it ends in "(?)" with a number, the model changed after numbering. Number the model and export again to get reliable marks. Open the optimizer →

Yes. After a takeoff in the viewer, press "Cutting plan →" to send the member list straight to the optimizer. The list is passed through your own browser, not over the internet. Free tools →

Yes: free, no sign-up, no account. They run in your browser, and your files never leave your computer. Free tools →
