Material & grades
Yield strength, tensile strength, ductility, toughness, weldability, chemistry, and product form all affect selection and use. “Steel” is a family of controlled materials, not one interchangeable substance.

01
Steel fundamentals
Structural steel fundamentals, shape designations, and load paths.
Structural steel starts with material properties and standardized shapes, then becomes a system that carries load through members and connections to the foundation.
Shapes & products
Wide-flange shapes, channels, angles, tees, HSS, pipe, plate, bar, deck, joists, and cold-formed members each carry different geometry, properties, availability, and fabrication implications.
Loads & load paths
Gravity, wind, seismic, equipment, temperature, construction, and erection loads move through slabs, beams, joists, columns, braces, connections, base plates, anchors, and foundations.
Connections
Bolts and welds join members, but a connection also defines force transfer, stiffness, ductility, fit-up, access, tolerance, inspection, and erection behavior.

Design & detailing
Structural steel design intent, connection engineering, and detailing.
Engineering establishes required performance. Detailing resolves that intent into coordinated, fabrication-ready information.
Contract information
Design drawings, specifications, schedules, addenda, RFIs, delegated-design notes, and reference models establish the project basis. Conflicts must be surfaced, not quietly guessed through.
Model development
Members gain exact work points, orientation, setbacks, connection materials, holes, welds, phases, sequences, finishes, and identifiers in a steel-aware model.
Shop & erection drawings
Shop drawings tell the fabricator how to make and inspect assemblies. Erection drawings tell the field where pieces go and how the structural system is organized.
Review & revision
Submittal review checks conformance to design intent; it does not transfer every responsibility. Revisions need a visible trail and coordinated regeneration of affected outputs.
See the seven information handoffs that connect the design model to fabricated and erected steel.

Shop & field
Steel fabrication, erection planning, and quality control.
Production and erection introduce real material, machines, tolerances, access, sequence, weather, and human factors.
Material control
Procurement, receiving, heat traceability, inventory, nesting, and cut lists connect specified material to the pieces that leave the shop.
Fabrication
Cutting, drilling, coping, fitting, welding, straightening, cleaning, coating, marking, and inspection transform stock into shippable assemblies.
Quality
Inspection plans, welder and procedure qualifications, dimensional checks, nondestructive examination, coating checks, and nonconformance control provide evidence of conformance.
Erection
Site access, crane planning, sequence, temporary stability, bolting, welding, decking, fall protection, tolerances, and field verification shape safe installation.
04
Digital steel
Structural steel BIM, automation, data exchange, and AI.
The most useful technology reduces re-entry, exposes differences, and keeps decisions traceable across teams and machines.
BIM & coordination
Discipline models, federated review, issue tracking, model sharing, and open formats help teams coordinate space, geometry, sequence, and responsibility.
Machine data
NC/CNC files, DSTV data, plate nesting, robotic layout, scanning, and shop-floor tracking carry digital information into production—and require validation.
Automation & APIs
Rules, scripts, plugins, and APIs can automate repeatable checks and outputs. Good automation reports assumptions, exceptions, and exactly what changed.
AI with guardrails
AI can assist search, classification, comparison, and drafting. Project decisions still require authoritative inputs, domain review, privacy controls, and accountable approval.

Pocket glossary
Structural steel detailing and fabrication terms worth knowing.
Definitions are intentionally plain-language starting points. Contract documents and governing standards may use more precise meanings.
- Piece mark
- A unique label used to identify a fabricated member or part.
- Work point
- A defined geometric reference used to locate and connect members.
- Camber
- An intentional upward curvature used to offset expected deflection.
- Cope
- A cut that removes part of a member, often to clear another member or connection.
- RFI
- A documented request for clarification of project information.
- BOM
- A bill of material listing parts, sizes, quantities, and related information.
- Embed

A few practical answers
Frequently asked questions
Which lessons include interactive practice?
The drawing, revision-control, shape-property, and information-workflow guides include selected annotated examples or self-check activities. Each activity explains its own fictional scenario.
Do exercises provide a professional qualification?
No. They are learning activities with explanations. Completion does not certify competence or authorize design, fabrication, or erection work.
Can I reproduce the examples in the tools?
Use the downloadable practice project to compare PDF revisions, check material quantities, and inspect a project handoff with known results.
