Beam-to-Column Connections
Connection elevations and sections for framing joints, including shear tabs, clip angles, end plates, plate thicknesses and fastening references from approved design information.
Structural steel / connection detailing
Structural Connection Drawings & Steel Connection Detailing
Develop coordinated bolted and welded connection drawing packages for structural steel fabrication and construction review. We document approved connection requirements, member interfaces, plates, bolt patterns and weld callouts with consistent drawing references.
Bolted & welded detailsShop drawing coordinationControlled revisions
Conceptual detail only. Final dimensions and connection requirements must follow authorized engineering documents.
Connection documentation scope
Steel connection details prepared around approved design intent
Our detailing support translates structural connection schedules, design sketches and issued-for-review drawings into consistent 2D detail packages. Where loads, sizes or attachment requirements are unclear, open items are identified for the responsible engineer rather than assumed.
Beam-to-Beam Connections
Secondary beam framing, bolted seats, coping interfaces and erection clearances documented for fabrication and construction coordination.
Base Plates & Anchor Details
Column base plate layouts, anchor bolt positions, stiffeners, leveling interfaces and foundation coordination based on project-approved criteria.
Bracing & Gusset Plates
Gusset geometry, brace end connections, plate edges and bolt or weld references aligned with structural framing and engineer-issued connection requirements.
Moment & Special Connections
Drawing support for moment-resisting joints, stiffeners and specialty connection arrangements when their design, detailing criteria and applicable limitations are provided.
Bolted & Welded Shop Details
Connection component dimensions, hole patterns, welding symbols, part references and drawing revisions for controlled detail review.
Typical drawing package
Connection deliverables for fabrication and design-team review
Outputs and file formats are defined by the approved scope, available inputs and project review stage.
- Connection general arrangements, elevations, sections and detail views
- Beam, column, bracing and base plate connection drawings
- Bolt group, hole, plate and weld information from approved details
- Connection component and piece-mark references
- Coordinated DWG/PDF issue sets and annotated revisions
- Connection query registers and marked-up review responses when contracted
Drawing workflow
Controlled development from inputs to reviewed connection details
We organize connection documentation to reduce ambiguity between structural design requirements and fabrication drawings.
Scope & input review
Confirm the connection list, governing drawings, drawing stages and responsible review parties.
Draft & coordinate
Prepare detail geometry, connection callouts, part references and framing interfaces.
Check & resolve queries
Cross-check drawings against approved information and refer unresolved design decisions for clarification.
Issue & revise
Submit coordinated deliverables for authorized review and incorporate documented changes.
Clear responsibility boundaries
Drawing production is distinct from engineering approval
Connection capacity, seismic detailing, member forces, weld sizing and structural adequacy require qualified engineering assessment. Drafting based on design inputs does not itself certify a connection as suitable for fabrication or construction.
Any connection engineering calculations or design changes must be explicitly included in the contract and assigned to qualified project professionals. Review, stamping, code interpretation and fabrication-release authority remain with the designated engineer or approving party.
Frequently asked questions
Structural connection drawing FAQs
Can you prepare details for both bolted and welded connections?
Yes. The detailing scope can cover bolted and welded structural joints using the applicable approved sketches, framing layouts, material requirements and project drawing standards.
What must be supplied before steel connection detailing begins?
Current framing plans, member sizes, issued connection requirements, relevant fastening specifications, fabricator conventions and drawing status are typically needed. Missing design criteria are referred to the responsible engineer.
Do connection drawings include engineering calculations?
Not automatically. Drafting and structural connection design are separate scopes. Calculation and design support must be expressly agreed and assigned to qualified engineers.
Are drawings ready to fabricate as soon as they are delivered?
No. Drawings must pass the project's designated technical reviews and obtain the required authorization before they are released for fabrication or site use.
