If you want to do construction work for the state, you generally need to be registered with the CIDB and graded. The grade caps the value of the work you may tender for, which makes it a commercial constraint rather than an administrative one.
What the grade means
Registration places a contractor in a class of works and at a grade level. The level corresponds to a tender value range — the maximum size of contract you may be awarded in the ordinary course.
Bidding above your grade generally means disqualification, whatever the merits of the bid. So the grade is the first thing to check against any opportunity, before spending time on it.
How grading is assessed
Broadly, on financial capability and on track record. Financial capability looks at the resources available to the business; track record looks at works of a similar nature you have completed, with evidence.
That combination has a practical consequence worth understanding early: you cannot jump. Grades are built by completing work at your current level and documenting it properly, then applying with that evidence.
Document projects as you finish them
This is the part that separates contractors who progress from those who stay put. Completion certificates, signed confirmation of value and scope, the client's details, the dates.
Gathering it at the end of a project takes an hour. Gathering it two years later, from a client whose project manager has left, is frequently impossible — and an undocumented project is one that cannot count towards your next grade.
Keep the registration current
Registration is renewed periodically and a lapsed registration is the same as none at the moment a tender closes. Diarise it with your other annual compliance items.
The same applies to everything the grading assumes — tax compliance, B-BBEE, the Compensation Fund letter. A valid grade with an expired tax status is still a failed bid.
Joint ventures
Where a project is above your grade, a joint venture with a higher-graded contractor is a legitimate route, and it is how many contractors gain the experience to progress.
Structure it properly and in writing: who does what, who carries what risk, how the money flows, and who owns the track record afterwards. That last point matters — a joint venture that leaves you without documented experience has cost you the main long-term benefit.
Be realistic about capacity
A grade permits you to bid; it does not mean you can deliver. Contractors who win work beyond their operational or cash capacity fail publicly, and the reputational damage in a small market lasts.
