Most building work in South Africa runs on a JBCC agreement, and most of the builders who sign one have never read past the contract data. That isn’t laziness. The agreement is long, it refers to itself by clause number, and the parts that decide when you get paid are spread across several of them.
This is the short version: which JBCC agreement your job is probably on, what the words in it mean, and the four places where builders lose money under it.
What the JBCC is
The Joint Building Contracts Committee is a non-profit company that represents the three sides of a building job: building owners and developers, the professional consultants who design and run the work, and general and specialist contractors. Because all three sides write the agreements together, they are the default for private building work, and the public sector uses the PBA too, with its own contract data for organs of state.
The agreements themselves are copyright and sold, not free. At the time of writing a printed Principal Building Agreement costs about R1,300 from the SAICE bookshop. The certificates and forms that go with the agreements are free on JBCC’s free forms page.
The five agreements, and which one your job is on
JBCC publishes five agreements, and its own quick guide points each one at a different size and shape of job:
| Agreement | Who signs it, and what JBCC suggests it for |
|---|---|
| Principal Building Agreement (PBA) | Employer and main contractor, with a principal agent running the contract. Complex projects, roughly longer than nine months or above R5 million. |
| Nominated/Selected Subcontract Agreement (NSSA) | Main contractor and a subcontractor the employer nominated or selected. Only under a PBA, never with the Minor Works Agreement. |
| Minor Works Agreement (MWA) | Employer and contractor, with a principal agent. Simpler projects of up to nine months and R15 million, with no nominated subcontractors and no design by the contractor. |
| Small and Simple Works Contract (SSWC) | Employer and contractor directly; an agent is optional. Alterations, renovations and additions, or simple new buildings of up to three storeys, up to nine months and R5 million. |
| Direct Contractors’ Contract (DCC) | Employer and a specialist working alongside the main contractor: kitchens, non-central air conditioning, tenant installations. The work finishes before the main contract reaches practical completion. |
For a house, an extension or a renovation you will most often meet the Minor Works Agreement or the Small and Simple Works Contract. The Principal Building Agreement turns up on bigger and commercial jobs. The cover tells you which agreement it is. The contract data, the schedule filled in for your job, tells you how it has been set up.
Which edition, and why to check
JBCC reissued its agreements in June 2024, printed as Edition 6.3 of the PBA and 5.3 of the MWA. It describes the changes as minimal, mostly corrections, and says the May 2018 editions (6.2 and 5.2) remain valid until further notice, so a contract signed today may be on either. Older editions such as 4.1 still turn up, particularly in public tender documents.
Two practical points. Quote clause numbers from the edition printed on the cover of your agreement: the clauses were renumbered between editions, and a letter that cites the wrong one is easy to brush aside. And match the forms to the edition. JBCC’s free forms were drawn up for the 2018 editions, and the 2024 Minor Works Agreement warns that forms from earlier editions aren’t compatible with it.
Eight words that do most of the work
| Word | What it means on site |
|---|---|
| Principal agent | The person the employer appoints to run the contract, usually the architect or project manager. Under the PBA and the MWA, only the principal agent certifies payment and completion. Instructions come from the principal agent, or from another agent the contract data says may give them. |
| Contract data | The schedule completed for your job: the security option, the penalty per day, the payment dates and whether materials on site are paid for. Read it before you read the agreement. |
| Contract instruction | How a change is made: in writing, from the principal agent or an agent the contract data names. Verbal instructions happen, and you will have to prove them. The variation order form exists for exactly that. |
| Security | What the PBA has instead of retention. Variable security is a guarantee that starts at 10% and steps down at practical and final completion. Fixed security is a 5% guarantee plus a 5% payment reduction off your certificates. The MWA offers its own options, and the Small and Simple Works Contract still calls it retention. How it is released. |
| Payment certificate | The principal agent’s monthly certificate of what you are owed, and the number you will actually be paid. What is on it, line by line. |
| Recovery statement | Issued with each certificate, for money that moves without changing the contract value: penalties, interest, and an advance payment being paid back. |
| Practical completion | The certificate that stops penalties and starts the defects liability period, ninety days by default under the PBA. Final completion follows once the listed defects are fixed, and not before that period ends. The dates that follow it. |
| Adjudication | The quicker dispute route JBCC provides, run under its own adjudication rules, which are free on its website. |
Where builders lose money on a JBCC job
Rarely in the clauses everyone argues about. Usually in four quieter places:
- Changes made on a word. The client asks, the foreman does it, nobody writes a contract instruction, and the final account is priced off the original drawing. Record every change before the work starts.
- Claim deadlines. To claim more time or money you give notice first, then submit the detailed claim. For a claim arising from a contract instruction, the current PBA’s default is 20 working days for the notice and 40 for the claim, and the contract data can change both. Miss the notice and the claim can be lost outright; a High Court held exactly that in 2012, under an older edition. Diarise the notice the day the delay or the instruction happens.
- The contract data, unread. The security option, payment for materials on site, the penalty per day and the payment dates are all set job by job. Two jobs on the same agreement can treat your cash completely differently.
- Certificates checked too late. A payment certificate that undervalues your work is easiest to correct before the next one is issued. At final account, the same difference is a dispute.
This is general information about how the JBCC agreements are used, not legal advice, and it doesn’t reproduce JBCC’s text. The periods above are defaults; your signed agreement, its contract data and any amendments govern. Where money or time is genuinely in dispute, speak to a construction attorney.
