Construction is one of the largest sectors in government procurement. To bid on construction tenders, you must be registered with the Construction Industry Development Board (CIDB) and hold the appropriate grading for the contract value. This guide covers registration, grading, and winning strategies.
CIDB Overview
The CIDB is the statutory body that regulates the construction industry in South Africa. All contractors working on public sector projects worth more than R200,000 must be registered.

CIDB Contractor Registration
Rather not work through the CIDB portal yourself? We prepare and lodge your Grade 1 registration, check your CSD and SARS records line up first (the usual reason applications stall), and send you the certificate and CRS number.
Includes the CIDB fee for one class of works. Grades 2-9 are quoted separately.
To register with CIDB:
- Visit cidb.org.za
- Complete the online registration form
- Submit required documents (CIPC, Tax Clearance, B-BBEE)
- Pay the registration fee

Frequently Asked Questions
How long does CIDB registration take?
Initial registration typically takes 4-6 weeks. Upgrades may take longer as they require assessment of completed projects.
Can I bid on multiple categories?
Yes. You can register for multiple categories (e.g., GB and CE) but each requires separate grading based on your capability in that category.
What is joint venture grading?
Two contractors can form a JV and combine their gradings for a specific tender. This allows smaller contractors to bid on larger projects.

No CSD, no government business
CSD Registration
Every government tender needs you on the Central Supplier Database first. We register your business on CSD, or fix a profile that is stuck or non-compliant, and map your commodity codes to real tender demand.
