The Essentials
Why Construction Contracts Are Different
A building project is not a single transaction — it is a chain of interlocking obligations running between an employer, a contractor, a professional team of architects and engineers, and often a web of subcontractors and suppliers, all working against a programme that changes as the project unfolds. Ordinary contract law still applies, but the industry has developed its own specialised toolkit to manage the risk that comes with that complexity.
Construction disputes are rarely about whether a contract exists — they're about what happens when reality diverges from the programme: a delay, a variation, a payment withheld, a defect discovered too late.
What makes construction law distinctive is the combination of technical and legal expertise it demands. A dispute over defective workmanship, for example, cannot be properly assessed without understanding both the contractual obligations and the underlying engineering or building standard that was allegedly breached. This is why construction disputes are so often resolved with the involvement of quantity surveyors, engineers and delay analysts working alongside the legal team.
Standard Form Contracts
Industry-developed agreements — JBCC, NEC, FIDIC and GCC — that allocate risk and set out detailed procedures for payment, delay and disputes.
Multiple Parties
Employer, contractor, principal agent, subcontractors and suppliers — each with distinct contractual relationships and different remedies available to them.
Fast Dispute Resolution
Because cash flow keeps a project alive, construction disputes lean heavily on quick, interim mechanisms like adjudication rather than lengthy litigation.
Practical tip: Whether you are an employer, contractor or subcontractor, the contract you sign at the outset — not the one you wish you'd signed once a dispute arises — governs your rights. Get it reviewed before you sign, not after a problem starts.
The Industry's Own Rulebooks
Standard Form Contracts: JBCC, NEC, FIDIC & GCC
Rather than drafting a bespoke agreement for every project, the South African construction industry relies heavily on a small number of standard form contracts, each recommended for use by the Construction Industry Development Board and the built environment professions. Each has its own philosophy for allocating risk between employer and contractor.
Read before you sign: Each of these contracts contains strict notice periods and procedural requirements — for claiming an extension of time, for example, or disputing a certificate. Missing a deadline built into the contract can forfeit a right you would otherwise have had, regardless of how strong the underlying claim is.
Choosing the right contract form — and understanding precisely how it allocates risk for delay, additional cost, and defects — is one of the most consequential decisions made at the very start of a project, often before a single brick is laid.
The Lifeblood of the Project
Payment, Retention & Certificates
More construction disputes turn on payment than on any other single issue. Standard form contracts address this through a formal certification process, designed to keep cash flowing to the contractor while protecting the employer against paying for work that has not been properly done.
| Mechanism | What It Does |
|---|---|
| Interim Payment Certificate | Issued periodically (often monthly) by the principal agent, certifying the value of work completed to date |
| Retention | A percentage of each certified payment withheld by the employer as security against defective work, released in stages after practical and final completion |
| Payment Notice / Pay-Less Notice | Formal notice an employer must give within a set period to dispute or reduce a certified amount — silence generally means the certified sum becomes due |
| Final Payment Certificate | Issued once the defects liability period has ended, closing out the account (subject to any outstanding disputes) |
Payment certificates aren't just administrative paperwork — under most standard form contracts, a properly issued certificate creates an enforceable obligation to pay, which is exactly why adjudication exists to enforce it quickly.
Practical tip: If you are a contractor and a certified payment isn't made on time, don't simply wait and hope. Most standard form contracts give you the right to suspend work, or refer the non-payment straight to adjudication — both of which are usually far faster and cheaper than a full civil claim.
When the Programme Slips
Delay, Extension of Time & Penalties
Very few construction projects finish exactly on the date originally programmed. What matters legally is not that a delay happened, but whose risk it was under the contract — and whether the contractor followed the correct procedure to claim relief for it.
Extension of Time
Where delay is caused by an employer risk event — late instructions, variations, or exceptional weather — the contractor can usually claim additional time without penalty.
Penalties & Damages for Delay
Where the contractor is responsible for the delay, the contract typically fixes a pre-agreed daily or weekly penalty, deducted from amounts otherwise due.
Notice Requirements
Almost every standard form contract requires the contractor to give timeous, formal notice of a delay event to preserve the right to claim — late notice can defeat an otherwise valid claim.
Concurrent delay — where both employer and contractor causes of delay overlap on the critical path at the same time — is one of the most technically contested issues in construction law, and often requires a proper delay analysis by an expert rather than a simple reading of the site diary.
Because penalty clauses (sometimes called "penalty for delay" or liquidated damages provisions) are pre-agreed in the contract, a court or adjudicator will generally enforce the figure as written, rather than requiring the employer to prove its actual loss — which is precisely why the figure agreed at signature matters so much.
The Handover & What Comes After
Practical Completion & Defects Liability
Practical completion is the point at which the works are complete enough for the employer to take occupation and use the building for its intended purpose, even though minor outstanding items — a "snag list" or "punch list" — may remain. It is a defined contractual milestone, not simply a subjective impression that a project "looks done".
Certificate of Practical Completion
The principal agent issues this certificate once the works meet the contractual standard for practical completion, triggering occupation and the start of the defects liability period.
Snag List Compiled
Minor defects and incomplete items are recorded and given to the contractor to remedy within an agreed period.
Defects Liability Period
A defined period (commonly around 3 to 12 months) during which the contractor remains obligated to return and rectify defects that emerge, at their own cost.
Certificate of Final Completion
Issued once the defects liability period ends and any outstanding defects have been made good, closing out the contractor's obligations under the agreement.
Practical tip: A defects liability period is not the outer limit of a contractor's liability for defective work — depending on the contract and the nature of the defect, latent defects that only emerge later can still give rise to a claim under the general law, sometimes years after final completion.
Fast, Binding, Interim
Adjudication: The First Line of Dispute Resolution
Adjudication is the construction industry's answer to a problem litigation was never built to solve: a project that cannot survive a two-year wait for a court date. Under the JBCC and most other standard form contracts, adjudication is the mandatory first-tier dispute resolution mechanism, giving a fast, binding but interim decision.
Adjudication offers a fast, binding but interim decision, ensuring cash flow and project continuity — critical, given how time sensitive construction projects are in the extreme.
A landmark Cape Town ruling. In Pro-Khaya Construction CC v City of Cape Town and Johan G Wasserman SC (Western Cape Division, 15 August 2025), the High Court gave crucial guidance on the enforceability of adjudicators' determinations and the narrow grounds on which a court may interfere. The judgment confirms that an adjudicator acts as an expert rather than an arbitrator — narrowing the scope for judicial review — and that adjudicators' determinations are enforceable almost as if they were court orders, subject only to narrow defences. Importantly, the court held that municipalities and state entities cannot resist enforcement of an adjudicator's decision by invoking administrative law principles unless jurisdiction is genuinely lacking.
The practical effect of this line of authority — going back to Basil Read (Pty) Ltd v Regent Devco (Pty) Ltd (2010) — is that once an adjudicator has ruled, the parties are bound and must give effect to that decision without delay, whether or not they agree with it, unless and until it is set aside by an arbitrator. Non-participation or a late response to an adjudication is a real risk, not a technicality to be brushed off.
Speed
Adjudications are typically decided within weeks, not the months or years a full court case can take.
Cash Flow
Designed above all to keep money — and therefore the project — moving, "pay now, argue later" is the underlying philosophy.
Provisional
An adjudicator's decision binds the parties immediately but remains open to being overturned later in arbitration or litigation.
Settling the Dispute for Good
Arbitration & Litigation
Adjudication resolves the immediate cash-flow crisis, but it does not finally determine who was right. Where a party is dissatisfied with an adjudicator's decision, or where the dispute falls outside the adjudication mechanism entirely, the matter typically proceeds to arbitration or, less commonly in this industry, to the ordinary courts.
| Route | Key Features |
|---|---|
| Arbitration | Private, binding, and final; the parties choose an arbitrator with relevant technical or legal expertise; generally confidential; procedure governed by the Arbitration Act and the contract's arbitration clause |
| Litigation | Heard in the ordinary courts; used where the contract does not provide for arbitration, or for disputes outside the arbitration clause's scope; public and subject to the normal rules of civil procedure |
Most standard form construction contracts specify arbitration as the final dispute resolution mechanism, rather than litigation. Where the parties want a genuinely final and binding outcome from someone with real construction industry experience — rather than a generalist judge — arbitration is usually the preferred route, and the contract typically requires it.
Because construction disputes are technically complex, both arbitration and litigation in this field typically involve expert evidence — from quantity surveyors on valuation and payment disputes, engineers on defects, and delay analysts on programme and extension of time claims — which materially affects both the cost and the duration of the process.
The industry's strong preference for adjudication and arbitration over litigation isn't accidental — it reflects decades of learning that construction disputes need speed and technical expertise that the ordinary court process wasn't designed to provide.
Learning From What Goes Wrong
Common Disputes & How to Avoid Them
Certain categories of dispute recur so often across the industry that they are almost predictable — which also means they are, to a real degree, preventable with the right advice at the right time.
Behind almost every one of these categories sits a common thread: a failure to follow the contract's own procedure at the time the issue arose. A variation instructed verbally but never confirmed in writing. A delay claim raised months late, after the notice period had already expired. A defect disputed informally rather than through the certificate mechanism the contract actually provides.
For Employers
Have your contract reviewed before signing, appoint a principal agent you trust to administer it properly, and respond formally — within the contractual timeframes — to every notice you receive.
For Contractors
Keep a disciplined paper trail — site diaries, instructions, correspondence — and never let a notice period for delay, variation or non-payment lapse without formally recording your claim.
Practical tip: The cheapest construction dispute is the one that never happens. Involving an attorney to review the contract and advise on procedure before a project starts is invariably cheaper than instructing one once a dispute has already escalated.
