Comprehensive Connection Design & Calculations

We provide complete steel connection engineering services that cover all aspects of design, verification, and documentation.

Types of Connections We Design

  • Bolted Connection Design — Shear, tension, slip-critical, and combined-force design per CSA S16 and AISC codes.

  • Welded Connection Design — Fillet, groove, and full penetration welds with proper force distribution and weld sizing.

  • Moment Connection Design — End plate, flange plate, and moment connections for rigid frames.

  • Splice Connection Design — Beam and column splices for multi-storey and modular construction systems.

  • Knife Connection Design — Slim, architectural details for stairs, glass supports, or architectural metal.

  • Gusset Plate and Bracing Connections — Seismic and non-seismic braced frame designs.

  • Shoring Waler & Strut Connections — Heavy-duty designs for temporary works experiencing large axial or bending forces.

  • Miscellaneous Metal Connections — Ladders, railings, stairs, and custom architectural steel assemblies.

Each connection is engineered to achieve maximum efficiency, code compliance, and constructability — all while meeting your project’s specific geometry, load requirements, and fabrication methods. Proper connection design ensures forces are transferred safely between structural members through a continuous load path.

Calculation Report Service

In addition to connection design, Sepco Consulting Engineers offers a dedicated Calculation Report Service — a specialized deliverable designed to help steel fabricators and metal fabricators meet client or stakeholder requirements for verified engineering documentation.

A calculation report demonstrates that the designed steel connections satisfy all structural and safety requirements. This includes verifying that forces are properly transferred through the structural system in accordance with load path principles. It provides formal assurance to owners, consultants, and authorities that the fabrication is based on sound engineering principles and meets code standards.

Our calculation reports include:

  • Detailed load analysis, connection design, and verification checks.

  • Compliance with CSA S16, AISC, and other relevant codes.

  • Connection sketches or excerpts from shop drawings.

  • Stamped and signed engineering documents when required.

This service is especially valuable when fabricators need to support their design submittals or prove the structural integrity and safety of their work to clients, building officials, or third-party reviewers.
Whether you need one connection checked or an entire structure certified, our calculation report service provides clear, defensible engineering documentation that enhances confidence and ensures compliance.

Steel Shop Drawings & Fabrication Drawings

We produce fabrication-ready shop drawings tailored for seamless coordination between the design office and the fabrication floor.

Our deliverables include:

  • Fully detailed steel shop drawings and fabrication drawings.

  • Complete bolt and weld schedules with standardized callouts.

  • CNC cutting machine data (DXF or NC files) for automated fabrication.

  • Fit-up and erection details to minimize field modifications.

  • Accurate quantity take-offs and material schedules.

We work closely with steel fabricators and metal fabricators to ensure every drawing reflects real-world fabrication practices, helping prevent delays, errors, and costly rework.

On-Site Consultation & Construction Support

Construction sites often present unexpected challenges. Our engineers provide on-site consultation services to help resolve field issues quickly and safely.

Whether it’s an unforeseen geometry issue, interference, or a need to modify a connection, our team visits the site to assess the condition, provide verbal guidance, and prepare immediate sketches or revisions.

If a formal report or stamped calculation is needed afterward, we issue it promptly. This flexible, hands-on approach allows projects to stay on schedule without compromising safety or compliance.

We also continue to support our clients through construction and post-completion, ensuring that every engineered detail performs as intended.


Engineering Calculations & Peer Review

Our engineers perform a wide range of analytical and verification services:

  • Comprehensive connection calculations for all connection types.

  • Finite element analysis (FEA) for complex or heavily loaded joints.

  • Peer review and optimization of third-party designs.

  • Retrofit and modification assessments for existing structures.

  • Design optimization to reduce material costs while maintaining safety.

All calculations can be delivered as signed, sealed, and stamped engineering reports, ready for submission to clients, building departments, or engineers of record.
