Hi, I'm Sergei
Senior Structural Steel Detailer · Tekla Structures

Fabrication-ready steel, modelled to the last bolt.

10+ years in Tekla Structures, delivering 3D models, shop and erection drawings for industrial and commercial projects in Australia, New Zealand and Russia. I also build Tekla Open API and IDEA StatiCa automation in C#.

Projects

Projects with a 3D badge open in an interactive viewer. You can rotate the model, isolate parts, cut sections and inspect each member's properties straight from the IFC.

What I do

From model setup to issue for fabrication

I run projects end to end, or join your team for a single package. I follow your drawing standards, templates and numbering conventions.

01

3D steel modelling

  • Industrial & commercial structures
  • Custom components & connections
  • Complex assemblies, pipe racks, frames
02

Drawings & outputs

  • GA and erection drawings
  • Assembly & single-part drawings
  • Reports, NC / DXF / CNC files
03

Checking & coordination

  • Model & clash checking
  • Numbering and revisions
  • RFIs and design clarifications
04

Team & standards

  • AS/NZS, AISC, EN, GOST
  • Drawing templates to client standard
  • Leading and mentoring detailers
Automation & software

I write tools that save detailing hours

A C#/.NET developer who works as a detailer, so the tools fix problems I hit on real projects.

C# / .NET 8 · IDEA StatiCa REST API

Connection design automation for IDEA StatiCa

A desktop app for a structural engineering bureau that replaced manual work in the IDEA StatiCa GUI. Engineers set up a parametric template once; the app runs the checks and produces the PDF calculation reports.

Simple ModeInteractive single-connection workflow: edit parameters and loads, run the check, review results, export a PDF.
Advanced ModeBatch runs from Excel. It covers every load sign combination and checks against user limits, including buckling.
Excel cases→Parametric template→IDEA check→pass / over-limit / fail PDFs
Tekla Open API · C# · WinForms

Tekla plugins & custom components

Plugins for connections and automated framing, custom components, and drawing and report templates. They make detailing faster and keep drawings consistent.

AI · MCP

AI-assisted Tekla workflows

Pet projects that connect AI tools to Tekla Structures through an MCP server. The AI can query, model and check a live model.

About

An engineer who likes to know how things are built

I've been detailing structural steel since 2011. I started at Lenmontage in Saint Petersburg and later led a team of steel designers in Moscow. Since 2021 I've worked remotely from Belgrade for an Australian client.

I care about models a fabrication shop can trust: clean numbering, consistent drawings, and connections that are checked before they reach the workshop. When a task keeps repeating, I write a tool for it in C#.
