CIDB Construction Industry Development Board contractor registration and grading.
The CIDB was established by the CIDB Act 38 of 2000. It is a Schedule 3A national public entity under the PFMA with a mandate to develop and regulate the South African construction industry.
Key function: Maintains the Register of Contractors (RoC) and the Register of Projects (RoP). Any contractor performing public sector construction work must be registered and graded.
Legal requirement: No public sector client may award a construction contract to an unregistered contractor.
The grading system determines the maximum rand value of projects a contractor can bid for.
| Grade | Max Tender Value (post-2019) | Track Record | Capital |
|---|---|---|---|
| 1 | R200,000 | None | None |
| 2 | R1,000,000 | Required | Required |
| 3 | R3,000,000 | Required | Required |
| 4 | R6,000,000 | Required | Required |
| 5 | R13,000,000 | Required | Required |
| 6 | R40,000,000 | Required | Required |
| 7 | R80,000,000 | Required | Required |
| 8 | R200,000,000 | Required | Required |
| 9 | No limit | Required | Required |
Tender value ranges were revised October 2019. Always verify current thresholds with the CIDB.
1. Track record (construction works capability) Projects completed in the past 5 years in the relevant class of works. Verified via project award letters, completion certificates, payment certificates, and bank statements.
2. Available capital Based on financial statements for the past 2 years. The CIDB considers the best annual turnover of the two years. Net asset value (total assets − total liabilities) plus any financial sponsorship determines available capital.
| Sponsor ownership stake | Maximum sponsorship |
|---|---|
| Financial institution (any) | No cap |
| 50%+ ownership of contractor | Full sponsorship |
| 25–49% ownership | ≤ 75% of required capital |
| < 25% ownership | ≤ 50% of required capital |
| Non-financial, any | ≤ 15% of sponsor's net asset value |
Each contractor is registered in one or more classes, identified by a two-letter code:
| Code | Class of Works |
|---|---|
| CE | Civil engineering |
| GB | General building |
| ME | Mechanical engineering |
| EB | Electrical engineering (buildings) |
| EI | Electrical engineering (infrastructure) |
| EP | Electrical engineering (power generation and supply) |
| SB | Specialist building works |
| SC | Specialist civil engineering works |
| SE | Specialist electrical works |
| SM | Specialist mechanical works |
A contractor's full designation reads as: 7GB (Grade 7, General Building) or 5CE (Grade 5, Civil Engineering).
Warning: Providing false information is a punishable offence under the CIDB Act and Regulations.
The CIDB publishes the Standard for Uniformity in Construction Procurement for public sector tender structuring:
The CIDB publishes guidelines (e.g., Guideline A6) with templates for tender notice wording, evaluation criteria, grading designation requirements, and Register of Projects reporting.
Became law April 2021. Targets infrastructure projects valued at R60 million and above.
