Generic vs. Site-Specific Engineered Drawings: What You Really Need to Know

Understanding Engineered Drawings for Steel Buildings

When planning a steel building, one of the most important — and often misunderstood — parts of the process is engineered drawings. These drawings are essential for permitting, inspections, and code compliance. The type you need depends on how and where your building will be installed.

At The NC Builders, we want you to understand the difference between generic engineered drawings and site-specific engineered drawings. We’ll also explain why drawings are no longer free across the industry and how to determine which option your project requires.

What Are Engineered Drawings for Steel Buildings?

Engineered drawings are professionally reviewed and stamped plans that demonstrate how a steel building is designed to perform under specific loads and conditions.

They typically include:

• Structural framing layouts

• Connection details

• Load calculations

• Anchoring and foundation notes

• Code compliance information

  
  

Most municipalities require engineered drawings before issuing a building permit. This ensures that your project meets safety and regulatory standards.

Generic (Modified Generic) Engineered Drawings

Generic engineered drawings, often referred to as modified generic drawings, are pre-engineered plans that apply to a range of steel building sizes and configurations.

These drawings are commonly used for:

• Garages

• Workshops

• Storage buildings

• Agricultural or utility structures

  
  

Why Generic Drawings Are No Longer Free

The steel building industry has largely moved away from offering “free” drawings. Even generic plans must be:

• Reviewed by an engineer

• Modified to match your building size and layout

• Stamped for code compliance

  
  

Because of this, most manufacturers now charge between $50 and $300 for modified generic engineered drawings. At The NC Builders, we provide engineered drawings only after a client places their dealer service payment. This ensures that engineering resources are allocated to active projects and that drawings are accurate, compliant, and not rushed.

Site-Specific Engineered Drawings

Site-specific engineered drawings are custom-designed for one exact location. These plans take into account:

• Wind speed requirements

• Snow loads

• Seismic considerations

• Exposure category

• Local building codes

  
  

Site-specific drawings are required for:

• Livable or conditioned structures

• High wind load areas, including Florida

• Buildings in stricter code jurisdictions

  
  

They involve additional engineering time and review, which is why they cost more than modified generic drawings.

Why Some Areas Require Site-Specific Drawings for Standard Buildings

Many clients are surprised to learn that some municipalities require site-specific engineered drawings even for garages or workshops. This requirement depends on:

• Local code enforcement policies

• Regional wind or snow load requirements

• Updated state or county building standards

  
  

Assuming generic drawings will be accepted can lead to:

• Permit delays

• Additional engineering fees

• Project setbacks

  
  

How to Know Which Engineered Drawings You Need

Before ordering your steel building, follow these steps:

1. Contact your local building department to confirm drawing requirements.

2. Talk with your building specialist at The NC Builders to match those requirements correctly.

   
   

Choosing the right engineered drawings from the beginning saves time, money, and frustration.

Our Approach at The NC Builders

We believe in doing things the right way — not the rushed way. By requiring a dealer service payment before issuing engineered drawings, we ensure:
