A contractor isn't simply "CIDB Grade 8" — a more useful description is something like "Grade 8 GB" or "Grade 7 CE," because the grade and the class of works together describe the contractor's actual registered capability. This distinction matters when businesses evaluate construction tenders and check whether a contractor is genuinely eligible.

Frequently Asked Questions
What are the main CIDB work classes?
General Building (GB), Civil Engineering (CE), Electrical Engineering, Mechanical Engineering and Specialist Works.
Why does the class matter alongside the grade number?
Because a grade alone doesn't say what type of construction work the contractor is registered and capable of doing.
Are specialist works a separate category entirely?
No — CIDB's procurement guidance explains that specialist works form a subset of the primary categories.
