Most CIDB-Registered Contractors Sit in Just Two of Its Five Work Classes

CIDB grades contractors across five classes — General Building, Civil Engineering, Mechanical Engineering, Electrical Engineering Building and Electrical Engineering Infrastructure — but the register is dominated by General Building and Civil Engineering, and a contractor's grade in one class doesn't transfer to another.

For emerging contractors, understanding that grading is both a number (financial capacity) and a letter code (type of work) is essential before bidding — public sector clients will disqualify a tender specifying the wrong class regardless of price or quality. Diversifying into a new class often means starting the qualification process again.

Frequently Asked Questions

Can a Grade 6 civil engineering contractor automatically bid on Grade 6 building work?

No — grading is class-specific. A contractor must be separately registered and graded for each class of work they want to tender in.

Which CIDB classes are the biggest, in terms of registered contractors?

General Building (GB) and Civil Engineering (CE) are the most common entry points, reflecting the broad availability of that kind of public sector work.

Do I need a different CIDB grade for each class I register in?

Yes — your grade in one class does not carry over to another class; each is assessed on its own financial and track-record criteria.
