Verbal Instructions on Construction Projects — When a Site Direction Becomes a Variation

Practical guidance for contractors on protecting variation entitlement when work is directed verbally on Australian and New Zealand construction projects.

Executive Summary

Verbal site directions are a daily reality on construction projects. A superintendent walks the site, points at a problem, and says “fix it.” The crew mobilises. The work gets done. No written instruction is ever issued.

That direction may well be a variation. The cost is real. The entitlement may exist. But without the right response from your team in the hours and days that follow, recovery is likely gone.

This article explains when a verbal direction creates a legitimate variation entitlement, how standard form contracts treat verbal instructions, and what your commercial and site teams need to do — immediately — to preserve the claim.

It is written for CEOs, General Managers, Commercial Managers, Project Directors, and Contract Administrators who are responsible for protecting contractor-side commercial outcomes under Australian and New Zealand contracts.

 

Industry Context

How Verbal Directions Become Commercial Problems

Construction sites run on verbal communication. Instructions are given at daily pre-starts, during superintendent site walks, over the phone, and in passing conversation. That is the practical reality of project delivery, and it is not going to change.

The commercial problem arises because most construction contracts require variations to be instructed in writing. Where a superintendent directs additional or changed work verbally and no written instruction follows, contractors frequently absorb the cost — either because they do not recognise the direction as a variation, or because they assume the written instruction will come later.

It often does not. And by the time the final account is prepared, the notice period has expired, the records are incomplete, and the claim is rejected on procedural grounds. The work was done. The cost was real. But the entitlement is gone.

Why Principals Push Back

Principal organisations and their superintendents face genuine governance and budget scrutiny. Accepting a verbal instruction claim without a paper trail creates audit risk. Rejecting it on notice or procedural grounds is the path of least resistance — even where the underlying work is not disputed.

This is not always bad faith. It is the contractual mechanism operating as designed. The notice regime exists to give the Principal visibility of cost exposure in real time. Contractors who do not engage with that mechanism cannot reasonably expect the Principal to absorb the consequence.

The Contracts That Govern This
The issue arises across all major standard forms used in the region:

1. AS 4000 – 1997 (and AS 2124 – 1992): Clause 36 requires the superintendent to issue a written direction. Clause 40 provides the contractor with a right to claim where a direction is given, but notice obligations apply.

2. NZS 3910:2013: Clause 9 governs variations. Verbal instructions may be valid but must be confirmed in writing within a prescribed period, or entitlement to claim additional payment may be limited.

3. GC21 (NSW Government): Clause 42 requires written instructions, though clause 43 preserves some contractor rights where verbal directions can be substantiated.

4. Bespoke D&C and EPC contracts: These often impose the strictest requirements — written instruction only, with time bars as short as 7 days.

The common thread: verbal alone is almost never enough. What matters is what your team does in the period immediately after the direction is given.

 

When a Verbal Direction Creates Entitlement

The Entitlement Question

Not every verbal direction is a variation. The first question is always whether the work directed falls within the original scope of the contract. If the superintendent is directing work the contractor was already obliged to perform, there is no variation entitlement regardless of how the direction was given.

A verbal direction is more likely to create variation entitlement where it involves:

  1. Work that is clearly additional to or different from the contracted scope.

  2. A change to the method, sequence, or timing of work that increases cost.

  3. Rectification of a principal-supplied design error or site condition discrepancy.

  4. An acceleration direction — a direction to complete earlier than the contracted date.

  5. Work required to address a utility conflict, unexpected obstruction, or changed site condition that was not reasonably foreseeable at tender.

Where the direction falls into one of these categories, entitlement may exist. The question then becomes: can you establish it?

The Contractual Trap: ‘No Instruction, No Variation’
Many contracts include a clause to the effect that no variation shall be recognised unless it is instructed in writing by the superintendent. This is sometimes called a ‘no oral variation’ or ‘written instruction only’ clause.

Contractors often read this as a complete bar. In practice, it may not be — but challenging it requires evidence and legal grounding that many contractors simply cannot produce after the fact.

Courts and tribunals in Australia and New Zealand have, in some circumstances, recognised variation entitlement arising from verbal directions — particularly where the principal’s conduct makes strict reliance on a ‘written instruction only’ clause unconscionable or where a course of conduct has been established. These outcomes are not guaranteed, and litigation is expensive. Prevention is always the better path.

 

What Your Team Must Do — and When

The First 24 Hours Are Critical
The moment a verbal direction is given — whether at a site meeting, during a walk, or over the phone — the clock starts. Your team’s response in the following 24 hours will largely determine whether the entitlement survives.

Step 1: Identify and Record the Direction Immediately
The site supervisor or foreman who receives the verbal direction should record it the same day: who gave it, what was directed, where, and when. A dated site diary entry is the minimum. A photograph of the relevant site area or condition strengthens the record.

Do not rely on memory. Do not assume the direction will be confirmed in writing. Record it as though it will never be confirmed, because often it will not be.

Step 2: Confirm in Writing to the Superintendent — Same Day or Next Morning
Issue a written confirmation of the verbal direction to the superintendent by email. Keep it factual and brief. The purpose is not to argue entitlement at this stage — it is to create a contemporaneous written record of what was directed.

Example confirmation (adapt to your contract and facts):
“Dear [Superintendent], we confirm the verbal direction received from [name] at approximately [time] today at [location] to [description of work directed]. We will proceed on this basis and will be submitting a variation notice in accordance with the contract. Please confirm by return if this record is inaccurate in any respect.”

Step 3: Raise a Formal Variation Notice

Depending on your contract, a variation notice must be issued within a defined period — commonly 7, 14, or 28 days from the trigger event. Do not wait until the scope or cost is fully known. Issue the notice first. Quantify later.

The notice should identify the direction (cross-referencing your written confirmation), the clause under which entitlement is claimed, and a statement that cost and time impact will be provided in a subsequent submission.

Step 4: Cost-Code and Segregate the Work

Assign a dedicated cost code to the verbally-directed work the moment work commences. Labour, plant, materials, and subcontractor costs must be captured separately from base contract costs. Without this segregation, quantum cannot be established at claim stage regardless of entitlement.

Step 5: Submit the Variation Claim With Supporting Evidence
Once the work is sufficiently progressed or complete, submit a structured variation claim with a quantum build-up cross-referenced to: the written confirmation of verbal direction, the variation notice, cost records (timesheets, dockets, invoices), and any photographs or site records establishing the scope.

 

Common Failure Scenarios

The table below maps the most frequent failure points when verbal directions are not properly managed, and the commercial consequence of each.

Failure Commercial Consequence
No contemporaneous record The superintendent denies the direction occurred or disputes its scope. No corroborating evidence exists. Claim fails entirely.
Confirmation email not sent No written record of the verbal direction is created. The contractor is left relying on oral testimony, which is difficult and costly to establish in dispute.
Variation notice out of time Notice is issued after the contractual period expires. Entitlement is extinguished regardless of whether the work was performed and the cost incurred.
Work cost-pooled with base contract No separation of costs for the directed work. Quantum cannot be established. Even where entitlement is accepted, the claim is significantly reduced or rejected on evidence grounds.
‘We’ll sort it out at the end’ Entitlement preserved informally but never formally noticed. At close-out, the claim is rejected on time bar grounds. The cost has already been incurred.
Verbal instruction confirmed in writing — late Confirmation issued after the notice period has expired. The Superintendent uses the delay to argue that no direction was given at the relevant time.

 

Case Example

Scenario: Building Contractor — Commercial Fitout, Superintendent-Directed Scope Change

The Situation
During a superintendent site walk on a commercial fitout project, the superintendent directed the contractor’s site manager to relocate a series of partition walls and upgrade the specified acoustic treatment to a higher specification. The direction was given verbally in front of two subcontractors. No written instruction was issued. The site manager instructed the subcontractors to proceed.

The Failures
No written confirmation of the verbal direction was issued. No variation notice was submitted. The work was completed over two weeks and the cost — approximately 85,000 — was absorbed into the general contract cost pool. The variation was raised for the first time in the final account, submitted 60 days after practical completion.

The Consequence
The principal rejected the claim on three grounds: no written instruction had been issued, notice had not been given within the 14-day contractual period, and no cost segregation existed to support the quantum. The superintendent denied giving a direction of the scope claimed. The two subcontractors were unwilling to provide statutory declarations. 85,000 was written off.

What Should Have Happened
A same-day email confirming the verbal direction — copied to the principal — would have created the contemporaneous record needed to anchor the claim. A variation notice issued within the 14-day period would have preserved entitlement. A dedicated cost code would have segregated the quantum. Three steps, taken in the first 48 hours, would likely have recovered the full amount.

 

Key Takeaways

1. A verbal direction can create variation entitlement — but only if you act immediately.
The direction itself is not the problem. The failure to create a contemporaneous written record and issue a timely notice is where entitlement is lost.

2. Confirm the verbal direction in writing the same day.
A factual email to the superintendent confirming what was directed, when, and by whom creates the record your claim will depend on. Do not wait for the superintendent to issue a written instruction.

3. Issue the variation notice before the contractual deadline — not when the cost is known.
Notice first. Quantify later. Most contractors lose entitlement because they wait until they understand the full scope. The clock does not wait.

4. Cost-code verbally-directed work from the first day.
Without segregated cost records, even an accepted entitlement will be reduced on quantum grounds. Assign a dedicated cost code before the first resource is mobilised.

5. We’ll sort it at the end’ is not a commercial strategy.
Informally agreed variations that are never noticed are the most common and most preventable source of variation loss. Build the process. Train the teams. Apply it every time.

 

Practical Guidance

At Mobilisation

  1. Brief your site supervisors on the verbal instruction protocol before work starts. They need to know: what a variation looks like in the field, what to record, and who to notify. This briefing should be documented.

  2. Prepare a one-page ‘Verbal Instruction Response’ card for site supervisors. It should set out the four steps — record, confirm, notify, cost-code — in plain language. Put it in the site office.

  3. Establish cost code conventions for potential variation categories before the project starts. When a verbal direction is received, the cost code should be created the same day.

During Construction

  1. Review site diaries weekly at the commercial level. Supervisors may record verbal directions without escalating them. Commercial teams need visibility of these entries in time to issue notices.

  2. Where a superintendent refuses to issue a written instruction, escalate formally and document the refusal. A letter noting that a verbal direction was given and that a written instruction has been requested creates a useful record if the claim is later disputed.

  3. Do not rely on site meeting minutes to record verbal directions. Minutes are typically agreed retrospectively and are subject to editing. A contemporaneous diary entry or same-day email is far stronger evidence.

  4. Track notice deadlines actively. Set a calendar reminder for every verbal direction confirmation issued — pegged to the contractual notice period. If the formal notice is not raised before that date, escalate immediately.

At Close-Out

  1. Audit your variation register against site diary entries and confirmation emails before submitting the final account. Identify any directions that were informally actioned but never noticed. Take legal advice before submitting late claims.

  2. Where a principal disputes that a verbal direction was given, assemble the evidence: diary entries, emails, subcontractor records, photographs, and any witness statements available. Present the claim with the evidence mapped clearly to each element.

  3. Engage specialist advice early where verbal instruction disputes are material. The legal and commercial framework around oral variations is nuanced. A well-prepared claim position significantly improves outcomes.

 

How PCAG Adds Value

Verbal instruction disputes are among the most avoidable commercial losses in construction. They are also among the hardest to recover once the evidence is gone. PCAG works with contractors at every stage to prevent loss and maximise recovery.

Site Team Training and Protocol Design
We develop verbal instruction response protocols and site supervisor briefings tailored to your contract and project type. The goal is to embed the right commercial habits at site level — where entitlement is won or lost.

Live Variation Register Management
We implement and maintain a variation register that captures verbal directions in real time, tracks notice deadlines, and flags risk to the commercial team before the clock runs out.

Claim Preparation and Evidence Mapping
Where verbal instruction disputes arise, we prepare a structured claim position with evidence mapped to each entitlement element — direction, notice, scope, quantum. A well-organised claim is significantly harder to reject on procedural grounds.

Negotiation and Dispute Resolution Support
We prepare the commercial position, engage with the principal’s team, and develop a settlement strategy that maximises recovery without unnecessary escalation. Where formal dispute processes are required, we prepare the contractor’s position from the ground up.

Are verbal directions on your project being absorbed without a claim?
If your site teams are receiving verbal directions and no confirmation, notice, or cost-coding process is in place, entitlement is leaking every week. PCAG can review your current position and implement a protocol that protects recovery from today.
