The Construction Industry Development Board, established under the CIDB Act 38 of 2000 and most recently amended by Gazette 49532 of October 2025, maintains the Register of Contractors. Public sector clients are legally prohibited from awarding construction contracts to unregistered contractors, and any construction tender above R200 000 requires a valid grading. Everything about a South African contractor’s growth path runs through this register.
|
Grade |
Single-contract limit |
Note |
|---|---|---|
|
Grade 1 |
R500 000 |
No qualifying criteria. No audited financials, no track record. R450 per class of works, activated within 48 working hours. |
|
Grade 2 |
R1 000 000 |
From here, audited financials and a verified track record are required. Applications take up to 21 working days. |
|
Grade 3 |
R3 000 000 |
Stronger project track record and capital base required. |
|
Grade 4 |
R6 000 000 |
Multiple completed projects at Grade 3 value and a financial capability assessment. |
|
Grade 5 |
R10 000 000 |
Substantial project portfolio and proven working capital. |
|
Grade 6 |
R13 000 000 and upward |
Established contractor with a multi-project track record. Published sources quote higher ceilings; confirm before pricing a near-threshold bid. |
|
Grades 7 to 9 |
R60 000 000 to unlimited |
Major and top-tier contractors. Grade 9 has no upper limit. |
2.1 How the grade is actually determined
The grade is the lower of two tests, assessed per class of works.
|
Test |
Definition |
Implication |
|---|---|---|
|
Financial capability |
Best annual turnover in the two preceding financial years, and available capital, being retained income plus shareholder loans plus net asset value |
Distributing profit early directly reduces the grade the company can hold |
|
Works capability |
The largest single contract completed in that class of works within the preceding five years, registered on the Register of Projects |
A hundred small contracts do not move this number; one large one does |
2.2 Grading is class-specific
|
Class |
Description |
Scope |
|---|---|---|
|
CE |
Civil Engineering |
Roads, bridges, dams |
|
GB |
General Building |
Houses, commercial buildings |
|
ME |
Mechanical Engineering |
HVAC, gas |
|
EP |
Electrical Engineering Infrastructure |
Power generation, transmission |
|
EB |
Electrical Engineering Building |
Wiring, lighting, distribution |
A contractor registered 4GB is authorised at Grade 4 for General Building and says nothing about civil engineering or electrical work. A company that starts in building and later wants civil work must build a separate track record in that class. This plan stays in General Building throughout for that reason: adding a class would restart the works capability clock at Grade 1 in the new class while consuming management attention that the working capital position cannot spare.
