Who We Are

An Illinois-Focused Steel Detailing Partner Fabricators Trust

Drafting Buddies is a US-focused CAD, BIM, and structural steel detailing outsourcing studio built for fabricators, erectors, and general contractors who need shop and erection drawings without the overhead of hiring and managing an in-house detailing department.

For steel fabricators, structural engineers, and contractors across Illinois - from Chicago-area shops to Rockford, Peoria, and Springfield - we act as a direct extension of your team: reading your structural engineering drawings, modeling in Tekla Structures or Revit, and returning fabrication-ready drawings on a schedule your production line can plan around.

Every drawing set runs through named detailers, a dedicated project coordinator, and a structured checking pass before it reaches you - so what comes back is ready for the shop floor, not a rough first pass.

How we detail steel for Illinois fabricators

  • 01

    Built for Fabrication, Not Just Presentation

    Every drawing is dimensioned and detailed to what your shop actually needs to cut, fit, and weld - not a generic template.

  • 02

    Tekla, Revit & SDS/2 in One Studio

    Modeling and drafting handled in the software your engineering and fabrication teams already use, with clash-checked coordination.

  • 03

    Transparent Process, No Surprises

    Fixed quotes, defined revision rounds, and a named point of contact - every Illinois client knows exactly what they're getting and when.

Sub-Services

Structural Steel Detailing Sub-Services in Illinois

Nine specialized service lines covering every stage from structural shop drawings to full steel BIM modeling - priced and scoped separately so you only pay for what your project needs.

SP-01 · Core Detailing

Structural Steel Detailing Illinois

Complete structural steel detailing for Illinois commercial, industrial, and institutional projects - converting engineering drawings into fully dimensioned fabrication and erection documents. We detail primary framing, secondary members, and connections to AISC standards and your project's specific engineering requirements, coordinating with structural engineers on RFIs and design changes throughout. Deliverables are formatted to match your fabricator's shop standards and your erector's field sequencing needs, keeping the whole project moving without drawing-related delays.

  • AISC-standard detailing
  • Engineer coordination
  • Shop-matched formatting

SP-02 · Shop Drawings

Steel Shop Drawings & Fabrication Drawings Illinois

Fabrication-ready shop drawings built to the exact tolerances and formatting your Illinois shop's cutting, drilling, and welding process requires. We produce piece-mark drawings, material lists, and bolt/weld call-outs that align with your fabrication sequence, reducing shop-floor questions and rework. Every drawing set goes through internal checking against the structural model before delivery, so what reaches your shop is ready to run without a second review cycle.

  • Piece-mark drawings
  • Material lists
  • Bolt/weld call-outs

SP-03 · Erection

Steel Erection Drawings Illinois

Erection drawings and plans built for how your Illinois crew will actually sequence and lift steel in the field - piece placement, erection sequence, and field bolt/weld locations clearly marked for the erection foreman. We coordinate erection drawings directly against the shop drawing set so piece marks match exactly between fabrication and field documents, cutting down on the mismatches that cause delays and rework during steel erection.

  • Sequenced piece placement
  • Field bolt/weld marks
  • Shop-to-field consistency

SP-04 · Connections

Steel Connection Detailing Illinois

Bolted and welded connection detailing for beams, columns, and braces on Illinois structural steel projects - designed and detailed to satisfy engineering requirements while staying practical for shop fabrication. We work from engineer-approved connection designs or design connections per your project's delegated-design scope, producing clear connection drawings that eliminate ambiguity for both the fabrication shop and the field erection crew.

  • Bolted & welded detail
  • Delegated-design capable
  • Shop & field clarity

SP-05 · Framing

Beam, Column & Structural Framing Detailing Illinois

Detailed beam and column drawings for the primary structural framing of Illinois commercial, industrial, and residential steel projects - sizing, camber, coping, and connection prep detailed to fabrication tolerance. We handle framing detailing for everything from single-story warehouses to multi-story commercial frames, keeping every member drawing coordinated with the overall structural model so nothing gets missed between individual piece drawings and the full erection set.

  • Camber & coping detail
  • Multi-story capable
  • Model-coordinated

SP-06 · Misc Steel

Miscellaneous Steel & Stair/Railing Detailing Illinois

Miscellaneous steel detailing for stairs, railings, guardrails, ladders, and other secondary steel elements on Illinois projects - items that don't fit the primary structural package but still need fabrication-accurate drawings. We detail stair stringers, landings, handrails, and guardrail systems to code-required dimensions and your fabricator's connection standards, delivered as a coordinated miscellaneous steel package alongside or separate from your primary structural detailing scope.

  • Stairs & railings
  • Code-required dimensions
  • Standalone or bundled scope

SP-07 · Deck

Joist & Deck Detailing Illinois

Steel joist layout and metal deck detailing for Illinois roof and floor systems - joist placement, bridging, and deck panel layout coordinated with your primary structural steel drawings. We produce joist erection plans and deck fastening/attachment drawings that align with the framing below, helping your erection crew sequence joist and deck installation without conflicts against the structural steel schedule.

  • Joist placement plans
  • Deck panel layout
  • Framing-coordinated sequencing

SP-08 · BIM/3D

Tekla & Revit Steel BIM Modeling Illinois

Full 3D structural steel modeling in Tekla Structures or Revit for Illinois projects requiring BIM-based coordination and clash detection. We build LOD 300-400 steel models that generate accurate shop and erection drawings directly from the model, run clash detection against architectural, MEP, and concrete trades in Navisworks, and deliver coordinated model files alongside your drawing set for projects using a BIM execution plan.

  • Tekla & Revit modeling
  • Clash detection
  • LOD 300-400

SP-09 · Quality Control

Steel Drawing Checking & Quality Control Illinois

Independent drawing checking and quality control review for structural steel shop and erection drawings - whether produced by our team or reviewed as a standalone service for drawings from another detailer. We check dimensional accuracy, connection design compliance, and consistency between shop and erection drawing sets, flagging discrepancies before they reach the fabrication shop or the field, where corrections cost far more time and money.

  • Independent review
  • Dimensional accuracy
  • Pre-fabrication catch
