Understanding the CIDB Rating System in South Africa

Nov 3, 2025 | Tenders, Uncategorized

The CIDB rating is a vital system in the South African construction industry. It is a grading assigned to construction contractors by the Construction Industry Development Board (CIDB), a government body.

Essentially, a CIDB rating is a contractor’s “license to trade with government” and determines their eligibility to bid on and execute public sector construction projects.

What is a CIDB Rating?

The rating is a classification that certifies a contractor’s capability to undertake projects of a certain value and in a specific class of works

Format: A CIDB grade is represented by one digit and two letters, for example, 4GB

    • The Digit (1 to 9):Represents the contractor’s Grading Level.This determines the maximum value(the Tender Value Limit) of the construction project they are permitted to execute. Grade 1 is the lowest, and Grade 9 is the highest (no limit).
    • The Two Letters: Represents the Class of Works or type of construction the contractor is experienced in (e.g. General Building or Civil Engineering).

Example Of Common Classes of Work

Abbreviation Class of Works
GB General Building
CE Civil Engineering
ME Mechanical Engineering
EB Electrical Engineering (Building)
EP Electrical Engineering (Power)
SB Asphalt Works (supply and lay)

How Does the CIDB Rating System Work?

The grading system assesses a contractor’s capability based on two primary determinants: Financial Capability and Works Capability (Track Record)

Financial Capability

This assesses the contractor’s financial capacity to start and sustain a new project. 

The CIDB looks at:

    • Best Annual Turnover: The best turnover achieved in the immediate past two financial years.
    • Available Capital: Funds presumed available to the contractor (based on their financial statements) to service a project.

Works Capability / Track Record

This assesses the contractor’s proven experience in the specified class of works. 

The CIDB looks at:

    • Largest Completed Contract: The largest construction contract the contractor has successfully completed in the relevant class of works during the five years immediately preceding the application. This completed project must be registered on the Register of Projects (RoPs).

Grading Levels and Tender Value Limits

The maximum tender value a public sector client may award a contractor is strictly tied to their grading level.

Grading Level Maximum Tender Value Limit (Approximate Range) Requirements Based On
Grade 1 Up to R200,000 No qualifying criteria (entry level)
Grade 2 Up to R650,000 Financial & Track Record
Grade 3 Up to R2 Million Financial & Track Record
Grade 4 Up to R4 Million Financial & Track Record
Grade 5 Up to R6.5 Million Financial & Track Record
Grade 6 Up to R13 Million Financial & Track Record
Grade 7 Up to R40 Million Financial & Track Record
Grade 8 Up to R130 Million Financial & Track Record
Grade 9 No Limit (Any Size) Financial & Track Record
Grading Level Maximum Tender Value Limit (Approximate Range) Requirements Based On
Grade 1 Up to R200,000 NQC
Grade 2 Up to R650,000 FTR
Grade 3 Up to R2 Million FTR
Grade 4 Up to R4 Million FTR
Grade 5 Up to R6.5 Million FTR
Grade 6 Up to R13 Million FTR
Grade 7 Up to R40 Million FTR
Grade 8 Up to R130 Million FTR
Grade 9 No Limit (Any Size) FTR

FTR = Financial & Track Record

NQC= No Qualifying Criteria

Note: The exact tender value ranges are periodically adjusted by the Minister of Public Works in line with inflation

Key Takeaways

Prerequisite for Public Tenders

A contractor must be registered on the CIDB Register of Contractors to be awarded public sector construction contracts (typically for tenders valued above a certain threshold, like R200,000).

Tender Qualification

A contractor cannot bid on a tender that has a value higher than the limit stipulated by their current CIDB grading level.

Upgrade Paths

Contractors start at lower grades and apply for an upgrade as they successfully complete larger projects and increase their financial capacity, moving up the ladder toward Grade 9
