The Construction Industry Development Board (CIDB) grading system determines the maximum contract value a construction business may tender for, and in which category of work. Nearly every civil, building, or infrastructure tender specifies a minimum CIDB grade as a mandatory requirement — bid below your grade and you are simply not eligible to be evaluated.
A CIDB grading looks like "7CE" or "6GB." The number (1–9) is the grade, which sets your maximum tender value — grade 9 has no upper limit, while grade 1 caps you at a few hundred thousand rand. The letters are the class of work: CE is Civil Engineering, GB is General Building, EP is Electrical Engineering (Works), and so on. A tender requiring "minimum 6CE" needs a contractor graded 6 or higher specifically in the Civil Engineering class — a 9GB contractor with no CE registration does not qualify.
A business is often correctly graded for the work but tenders in the wrong class, or tenders above their grade because the estimated contract value was underestimated at the time of registration and never re-graded upward as turnover grew. Both are avoidable with a five-minute check against the tender's stated requirement before preparing a full bid.
Some tenders explicitly accept Potentially Emerging (PE) contractors — businesses one grade below the stated requirement, registered as PE for that class. If a tender states "6CE PE accepted," a correctly-registered 5CE PE contractor is still eligible. This is one of the more commonly missed opportunities: many businesses assume "minimum grade 6" is a hard floor when the tender document itself allows a PE exception.
