Delegated Steel Design: What It Is, Why It Matters, and How to Do It Right

In most building projects, the engineer of record (EOR) is responsible for designing the primary structural systems. This includes the overall structural framework and stability of the building. However, not every component is designed by that engineer directly.

That’s where delegated design comes in.

What Is Delegated Design?

Delegated design refers to situations where the engineer of record assigns parts of the structural design to another engineer. This is typically done through other project stakeholders such as the general contractor, steel fabricator, or specialty subcontractor.

Some common components handled through delegated design include:

• Steel connection design
• Stair and railing design
• Ladders, platforms, and catwalks
• Erection engineering
• Shop drawing review and stamping

Delegated design is not limited to steel. It also applies to systems in other materials, such as:

• Precast wall panels
• Tilt-up walls
• Elevator systems
• Light gauge metal studs, framing, or girts

Why Is Delegated Design Used?

There are several reasons why delegated design is a common practice:

• Cost Efficiency: It helps reduce overall engineering costs. The engineer of record can focus on the core structure while specialty firms handle more repetitive or niche components.
• Faster Turnaround: Firms that specialize in certain components often have tools and workflows that speed up delivery.
• Better Optimization: Specialty engineers understand the specific challenges of certain components and can often produce more efficient designs.
• Time Savings for the EOR: Instead of doing all the design work, the EOR can focus on reviewing the delegated designs for compliance, which is often much faster.

What Makes Delegated Design Work Well?

While delegated design offers many advantages, it must be managed correctly to avoid problems:

• Clear Communication: The engineer of record needs to communicate all design criteria and intent clearly and completely.
• Coordination: If coordination is lacking, the result can be misaligned designs, rework, or structural elements that don’t integrate properly.

When delegated design goes wrong, the issue is often not technical. Instead, the problem is usually a lack of communication or poor handoff between teams.
