Structural Steel Shop Drawing Checklist: What Fabricators Need Before the Job Starts
Every structural steel project lives or dies by the quality of its shop drawings. A fabricator who heads into the shop without a complete, reviewed set risks costly rework, field conflicts, and schedule delays that no one budgets for. This checklist covers the core deliverables your detailing partner should produce before fabrication begins — and what you need to hand over to get them there.
Why a Checklist Matters for Steel Shop Drawings
Structural steel shop drawings are the translation layer between the engineer's design intent and the fabricator's finished product. When a drawing package is incomplete — missing a connection detail, an anchor bolt plan, or a clear erection sequence — the gap shows up in the field. The cost to fix a connection detail in the shop is a fraction of the cost to fix it on the job site after steel is in the air.
A systematic checklist before fabrication starts is not extra work. It is the work that prevents emergency RFIs, change orders, and owner disputes.
What to Send Your Shop Drawings Detailer
Before your detailing partner can produce a complete package, they need the following from you:
Structural engineer's stamped drawings (latest revision)
Applicable design codes (AISC, IBC, local jurisdiction)
Connection design criteria or a connection design report
Material specifications (A36, A992, HSS grades, bolt grades)
Surface treatment requirements (prime paint spec, galvanizing, SSPC standards)
Project schedule with fabrication start and delivery milestones
Any architect or owner-specific requirements for drawing format or title block
Missing any of these at the start of detailing typically means either assumptions get made or the detailer stops and waits. Neither outcome is good. Get these documents together before you issue the detailing contract.
The Complete Structural Steel Shop Drawing Package
A complete shop drawing set for a structural steel project includes the following drawing types:
1. Anchor Bolt Plans
Anchor bolt plans are the first deliverable fabricators and general contractors need — often before any other steel work begins, because the bolts are set in the concrete foundation. These drawings show bolt diameter, grade, projection, group layout, and edge distances for every column base in the structure.
Column grid layout with coordinates
Anchor bolt diameter, grade, and quantity per group
Bolt projection above finished concrete elevation
Template or setting plate details if required
2. Erection Drawings
Erection drawings show the ironworker how pieces go together in the field. They are the overview drawings — full elevations and framing plans showing member locations, orientation marks, and the sequence of assembly.
Framing plans at each level
Elevation views of braced frames and moment frames
Piece mark callouts tied to the shipping list
High-strength bolt callouts and installation notes
3. Detail Drawings (Piece Marks)
Each fabricated piece gets its own detail drawing. This is where the shop sees every hole, every cut, every cope, and every weld. Detail drawings must be complete enough that a fabricator can make the piece with no additional information.
Overall dimensions and member size
Hole sizes, locations, and group layouts for bolted connections
Cope and clip dimensions
Weld sizes and symbols per AWS D1.1
Material grade and surface treatment callout
Weight per piece
4. Connection Details
Connection details resolve how members attach to each other. Shear tabs, moment connections, end plates, gusset plates — each connection type has its own geometry that has to be shown clearly and dimensioned fully.
Shear connections (single plate, double angle, seated)
Moment connections (end plate, flange plate, direct weld)
Brace connections (gusset plate geometry and edge distances)
Column base plate details with weld and anchor bolt callouts
5. Bill of Materials
Every shop drawing set should include a bill of materials — a complete list of all pieces, their marks, quantities, sizes, lengths, weights, and material grades. This is the purchasing and estimating document as much as it is a fabrication document.
Before You Approve for Fabrication: The Final Review Check
Before stamping a drawing package approved for fabrication, run through this final check:
All anchor bolt plans match the structural engineer's column schedule
Piece marks are unique and match the erection drawing callouts
Connection details match the engineer's connection design report
All holes are shown for both the member and the connecting element
Weld symbols are correctly specified (fillet vs. groove, size and length)
Material grades match the specification throughout
Camber requirements are called out where applicable
Bill of materials quantities add up against the erection drawing piece counts
Software: AutoCAD, Tekla, and Revit
The detailing software your partner uses affects the accuracy and the review cycle. Tekla Structures is the standard for complex structural steel projects — it produces a 3D model from which all drawing views are derived, which means connection geometry is checked in three dimensions before a drawing is printed. AutoCAD-based detailing is common for simpler structures and is widely accepted by fabricators. Revit is increasingly used for coordination with architectural and MEP models on BIM-required projects.
Shop Drawings Pro works in AutoCAD, Tekla, and Revit. If your project has a BIM requirement or a model coordination requirement, mention that at the outset so the right software and workflow is set up from the first drawing.
