A General Engineering Contractor specializes in large-scale projects that require advanced engineering knowledge and skill. The Class A license is the highest-level contractor’s license the CSLB issues, and it opens the door to the most substantial and highest-value construction contracts in California. RMO Construction Agency Inc helps contractors get their Class A license with fast approval, trusted RMOs from our network, and full support from consultation through license approval.
What Is a Class A General Engineering Contractor in California?
The Class A General Engineering Contractor license is issued by the California Contractors State License Board for contractors whose principal contracting business involves the use of engineering skills such as fixed works requiring specialized engineering knowledge and skill. The CSLB defines fixed works to include infrastructure and large-scale construction projects such as:
- Grading, clearing, and earthwork
- Highways, roads, streets, and bridges
- Pipelines, drainage, and irrigation systems
- Dams, reservoirs, and water treatment facilities
- Sewers, water mains, and utility systems
- Airports and railroads
- Tunnels and underground work
- Pile driving and foundation work
- Electrical and mechanical systems on large infrastructure projects
Class A work typically involves projects where engineering drawings and specifications are required and where the work product becomes a permanent part of the built environment at a scale that goes well beyond standard building construction. If your business is performing or intends to perform this category of work in California, the Class A license is not optional. It is the legal requirement for bidding and contracting on these projects.
The Class A also carries significant business value beyond compliance. Public agencies, municipalities, Caltrans, and large private developers require a Class A license from contractors before they will consider bids on major infrastructure and engineering projects. The Class A is the credential that gets your company in front of that market.
Fast Approval on Your Class A License Application
Fast approval starts with a complete, accurate application that gives the CSLB nothing to come back to you about. RMO Construction Agency prepares Class A applications that are thorough, correctly documented, and submitted with all required supporting materials. That means fewer requests for additional information, fewer delays in the review queue, and a faster path to the license number your company needs.
The CSLB processes applications on a rolling basis and the timeline reflects both their current workload and the completeness of the application they receive. A complete application from a company with the right qualifying individual documentation moves faster than an incomplete one that cycles through multiple rounds of back-and-forth. We prepare applications designed to move through the process cleanly the first time.
Trusted RMOs for Your Class A General Engineering License
The Class A qualifying individual requirement is the most demanding in the CSLB’s license structure. A Responsible Managing Officer or Employee who qualifies a Class A license must have four years of journeyman-level experience in the engineering trades covered by the classification, and that experience must be documented correctly and verifiably.
RMO Construction Agency maintains a network of licensed Class A qualifying individuals whose credentials have been verified, whose documentation is in order, and whose availability for new qualifying arrangements has been confirmed. These are trusted RMOs, not a directory of names. We have worked with our network RMOs through the qualification process before, which means when we match you with one, the arrangement is built on a foundation that the CSLB will recognize as legitimate.
For a Class A application, the quality of the RMO match matters more than in almost any other classification because the projects a Class A license covers attract greater scrutiny and because the stakes of a licensing compliance problem are higher when the projects involved are large public infrastructure contracts.
Full Support and Proven Results From Application to Approval
Full support means we handle every step of the Class A licensing process and you are not left to figure out any part of it on your own.
What full support covers:
- Free initial consultation to assess your situation and confirm the Class A is the right classification
- Business entity formation guidance if your corporation or LLC is not yet in place
- RMO identification and matching from our trusted network
- RMO agreement structuring that meets CSLB ownership, duty, and compliance requirements
- Complete application preparation including experience documentation, personnel of record filing, and all supporting materials
- Application review before submission to catch and correct any issues
- CSLB submission and tracking from filing through approval
- Response to any CSLB requests for additional information
- License confirmation and ongoing compliance guidance after approval
Proven results means we have successfully guided contractors through the Class A licensing process and we know what a complete, compliant application looks like. The licensing landscape changes as the CSLB updates its requirements and processes, and having a team that stays current on those changes is what keeps applications from running into avoidable problems.
Who Needs a Class A License in California
Contractors performing large-scale infrastructure work. If your business grades land, builds roads, installs pipelines, constructs drainage or irrigation systems, or performs any of the other engineering trades covered by the Class A, you need this license to contract for that work legally in California.
Contractors bidding on public works projects. Public agencies in California require licensed Class A contractors for infrastructure and engineering contracts. Without the license, your company cannot bid on that work regardless of your technical qualifications.
Contractors who want to scale into large-scale engineering projects. Many contractors start with a Class B General Building license and grow into engineering work. The Class A is the next step that opens the highest-value project categories in the California construction market.
Business owners who do not yet have Class A qualifying experience. If your business performs Class A work but you do not personally have the four years of qualifying engineering experience required to sit for the exam, an RMO from our network qualifies your company now while you build your own record.
The Difference Between Class A and Class B in California
The Class A and Class B licenses are the two general contractor classifications the CSLB issues, and the difference between them matters for knowing which one your business actually needs.
A Class B General Building Contractor license covers the construction of buildings and structures, including residential, commercial, and industrial buildings. Class B work is about structures: framing, roofing, interior finishes, and the systems that go into buildings.
A Class A General Engineering Contractor license covers the construction of fixed works requiring specialized engineering knowledge and skill. Class A work is about infrastructure: roads, bridges, pipelines, drainage systems, earthwork, and the large-scale civil engineering projects that shape the built environment at a scale beyond individual buildings.
A business that builds commercial buildings needs a Class B. A business that builds roads, installs pipelines, or grades land for large-scale development needs a Class A. Some businesses need both, and holding both licenses simultaneously is possible when the qualifying individual requirements are met.
RMO Construction Agency assists with both classifications and can advise on whether your business needs one, the other, or both based on the work you perform.

It is the license required to bid on public works infrastructure contracts and major private engineering projects in California.
Can I get a Class A license without taking the CSLB exam?
Yes, through an RMO arrangement. A licensed Class A Responsible Managing Officer qualifies your company with the CSLB so your business receives a new Class A license number without you sitting for the qualifying exam. RMO Construction Agency matches you with a trusted Class A RMO and handles the full application process.
How is the Class A license different from the Class B license in California?
The Class A covers large-scale infrastructure and engineering work including roads, pipelines, drainage, and earthwork. The Class B covers building construction including residential, commercial, and industrial structures. Some businesses need both, and RMO Construction Agency assists with applications for either classification.
How long does Class A license approval take with RMO Construction Agency?
