About the A — General Engineering License

A General Engineering (Class A) license in California authorizes contractors to perform work requiring specialized engineering knowledge and skill. This includes projects like roads, highways, bridges, dams, pipelines, irrigation systems, and utility infrastructure. General Engineering contractors typically work on large-scale civil projects that shape communities and infrastructure. California requires this license for any project where more than two unrelated building trades are used in a fixed work requiring specialized engineering. When hiring a Class A contractor, consumers should verify they have adequate insurance and bonding for the project scope, as these projects often involve significant investment and safety considerations. The CSLB oversees all Class A licensees to ensure public safety and professional standards.

About the C-8 — Concrete License

The C-8 Concrete license authorizes contractors to mix, pour, and finish concrete for a wide range of residential and commercial applications. This includes foundations, driveways, patios, sidewalks, retaining walls, and decorative concrete work like stamping and staining. Concrete is one of the most versatile and durable building materials, and proper installation requires significant skill and experience. Factors like mix design, reinforcement, curing conditions, and finishing techniques all affect the final product's strength and appearance. California's seismic requirements add another layer of complexity, particularly for foundation work. When hiring a C-8 contractor, ask about their experience with your specific project type, the concrete mix they recommend, and how they handle weather-related scheduling challenges.

Frequently Asked Questions

What does a Class A General Engineering license cover in California?

A Class A license covers projects requiring specialized engineering knowledge including roads, bridges, dams, pipelines, utilities, and other infrastructure work. It does not cover general building construction, which requires a Class B license.

Do I need a licensed General Engineering contractor?

Yes. California law requires any contractor performing engineering work valued at $500 or more to hold a valid CSLB license. Hiring an unlicensed contractor puts you at risk and may void your ability to file complaints with the CSLB.

What does a C-8 Concrete license cover?

A C-8 license covers all concrete work including mixing, forming, pouring, and finishing. This includes foundations, slabs, driveways, patios, sidewalks, retaining walls, and decorative concrete like stamped and stained finishes.
