Finish late on a South African building contract and the employer deducts a pre-agreed penalty for every day of overrun, straight off your payment certificate. The penalty rate is set in the contract data before you tender, courts will enforce it if it is a genuine pre-estimate of loss, and your only real defence is a properly claimed extension of time. On the other side of the same coin sit the guarantees you may be asked to provide: performance bonds and retention guarantees. Here is how both work.
Penalties for late completion
What other markets call liquidated damages, SA standard contracts call penalties: a fixed daily (or weekly) rate payable for each day the works run past the completion date without an excusable extension. The purpose is compensatory, not punitive. Courts enforce them provided the rate was a genuine pre-estimate of the employer's loss and is not so extravagant as to be purely punitive.
Under JBCC (clause 24), the employer inserts the penalty rate in the contract data before tender, and the Principal Agent levies the penalty through the payment certificate. Per JBCC guidance, a penalty that is not in respect of goods or services supplied does not attract VAT. The documents are at the JBCC.
Three rules worth knowing:
- Penalties are normally the exclusive remedy for late completion. Unless the contract says otherwise, the employer cannot stack general damages for lateness on top.
- Employer delay without an EOT can set time "at large". If the employer causes delay (late instructions, design changes) and no extension is granted, the fixed completion date can fall away entirely. Penalties then stop applying and the employer is left proving actual damages, which is much harder.
- There is no statutory cap. SA has no law limiting the total penalty; the contract rate governs, though a court may intervene where the result is wholly disproportionate.
Your working defence is the extension of time machinery: notify every employer-caused delay immediately and claim formally (see Variations, Claims and Extension of Time).
Performance guarantees and bonds
Most employers require the contractor to provide a construction guarantee (performance bond) securing completion. Two species, and the difference is everything:
- On-demand guarantee. The employer calls it by serving a written demand; no proof of loss is needed first. The JBCC construction guarantee is an on-demand form, typically callable when a certified amount is unpaid, the contract is terminated, or a provisional liquidation order is granted against the contractor.
- Conditional guarantee. The surety pays only once the employer proves actual loss, usually via an adjudication or court finding.
On quantum, JBCC guidance points to covering the two highest contiguous months of projected cash flow, capped around 12.5% of the contract sum; FIDIC and NEC contracts more commonly use about 10%.
Getting a bond as a small contractor
A small subbie asked for a bond typically:
- Approaches a surety company, insurer or a bank's trade finance desk.
- Is assessed on financial standing, track record and the project.
- Pays a premium, typically quoted in the 1 to 4% of bond value per year range (broker pricing varies; treat that as a range, not a promise).
- The surety issues the bond in the employer's favour. If you default, the employer claims from the surety, and the surety claims from you.
For very small contracts (roughly under R500,000), a bond is often unobtainable or uneconomic. The standard fallback is cash retention as the security mechanism instead (see Retention Money).
Retention guarantees
Some contracts let you swap cash retention for a retention guarantee: a bank or insurance instrument the employer holds instead of deducting cash from every certificate. The JBCC suite was an early adopter of this option in SA. It costs a premium but frees your cash flow, which on thin-margin work can be the difference between making payroll and not.
Worked example
Jabu's company finishes a school 12 days after the contractual completion date. The contract data sets the penalty at R5,000 per day, so the Principal Agent deducts R60,000 from the penultimate certificate. But Jabu had properly noticed and claimed an EOT for 5 days of employer-caused delay (late information from the PA). The PA grants the 5 days, and the penalty falls to 7 days at R5,000, R35,000. Without the written notice trail, all 12 days would have stood.
Common mistakes
- Tendering without reading the penalty rate. It is in the contract data; price the risk or negotiate it.
- Not claiming EOTs as you go. Penalties are calculated at the end, but the defence is built day by day.
- Signing an on-demand guarantee without grasping it. The employer can call it without proving loss; your argument comes afterwards.
- Confusing the bond premium with the exposure. The premium is 1 to 4%; the liability is the full bond value, and the surety will recover it from you.
- Letting retention plus a bond plus a penalty stack up. Total security across the contract can quietly exceed your margin. Add it up before you sign.
