Class of works

What a class of works describes

The cidb uses classes of works to organise different kinds of construction activity. The letters in a contractor's designation identify the registered category. General Building and Civil Engineering are examples, and there are other classes for electrical, mechanical and specified specialist work.

The class and the grade answer separate questions. In an illustrative designation such as 4GB, GB is the work category and the number is the level. A contractor registered in more than one class may have a different grade in each, so there is no single number that automatically applies to everything the business does.

Class definitions concern the nature of the construction work. A company's marketing description, registered name or broad statement that it offers all building services is not the same as a confirmed cidb class. The actual registration and defined work scope need to be compared.

Why scope matters more than a familiar label

A tender's required class should relate to the work to be performed. The contractor should read the tender documents and scope, rather than choosing a class solely from the project title. A project involving a building can contain different types of work, and the procurement documents determine what designation is being requested.

Broad classes also do not establish every specialist capability. cidb guidance makes clear that clients still need to consider the expertise, experience and resources relevant to the particular contract. A matching class does not replace a professional registration, licence or other technical requirement where one applies.

The guide to higher grades and different works classes explains why a strong grade in one class cannot simply be carried across to another. For an application, use the cidb evidence checklist to connect the proposed class to the contractor's actual project records.

Illustrative example: building experience and a civil tender

A contractor has a current General Building designation and notices a tender specifying Civil Engineering. The team should not assume that a high numerical grade in GB satisfies the CE requirement. It compares the tender's stated designation with the exact entries in the contractor's live registration.

If the work description and the required class appear inconsistent, the contractor uses the tender's clarification process. It does not silently substitute its preferred class or rewrite its company profile to suggest a registration it does not hold.

The contractor may have relevant experience that supports an application for another class, but that is a separate assessment supported by appropriate evidence. This example distinguishes technical experience, an application in progress and an active registered designation. None is interchangeable with the others merely because the business has completed construction work before.

What a class of works does not establish

A class of works is not a tender value limit, a B-BBEE status level or a ranking of how good a contractor is. The numerical grade, current registration status and contract-specific requirements still need attention. A class code on an old document does not prove that registration remains active.

A new company name or ownership change also should not be treated as proof that every desired class has been added. For cidb registration assistance, identify the exact work category sought and provide the records supporting it. The useful question is which recognised class fits the evidence and intended scope, not which label sounds broadest.
