Legal Advice on Construction Delays, EOT Claims and Time-Related Disputes
Construction delays can have significant commercial consequences.
A delayed project may lead to additional costs, disrupted procurement, extended site overheads, disputes over responsibility, or claims for liquidated damages.

Construction Delay Lawyers Melbourne
Construction delay disputes often turn on the terms of the construction contract and the circumstances that caused the delay.
A party may contend that delay was caused by:
-
Late information or instructions
-
Variations
-
Design changes
-
Restricted site access
-
Unforeseen site conditions
-
Defective or incomplete work
-
Delays by other contractors
-
Subcontractor delays
-
Material or equipment shortages
-
Authority or approval delays
-
Weather events
-
Industrial action
-
Events outside a party's control
-
Acts or omissions of the principal or developer
The legal question is not simply whether the project was delayed.
It may be necessary to determine:
-
Who was responsible for the delay?
-
Did the contract provide an entitlement to additional time?
-
Were the required notices given within the contractual timeframe?
-
What evidence supports the claimed delay?
-
What are the consequences of the delay under the contract?
These questions can become particularly important where an extension of time is disputed or liquidated damages are being claimed.
Extension of Time Claims
An extension of time, commonly referred to as an EOT, may allow a contractor to extend the contractual date for completion when a qualifying delay occurs.
Whether an EOT is available depends on the construction contract and the circumstances of the delay.
We advise builders and contractors on:
-
Identifying EOT entitlement
-
Reviewing extension of time clauses
-
Qualifying delay events
-
Notice requirements
-
Time bars
-
Supporting evidence
-
Delay analysis
-
Concurrent delay
-
Extensions of time for variations
-
Extensions of time arising from principal-caused delay
-
Extensions of time arising from third-party events
-
Rejected EOT claims
-
Disputed EOT entitlement
-
Consequences of failing to make an EOT claim
For developers and principals, we advise on assessing and responding to EOT claims, including whether the claimed event falls within the contractual extension-of-time regime and whether the contractor has complied with the relevant contractual requirements.
EOT Claims and Contractual Notice Requirements
Construction contracts commonly contain detailed procedures governing extensions of time.
These may require a contractor to give notice within a specified period after becoming aware of a delay event.
The contract may also require information about:
-
The cause of the delay
-
The anticipated effect on the programme
-
The period of delay claimed
-
Steps taken to mitigate the delay
-
Supporting records
-
Updated programmes
-
Further notices as the delay continues
Failure to comply with contractual notice requirements can create significant difficulties.
A delay may have occurred in reality, but the contractor may still face an argument that its contractual entitlement to an extension of time has been lost, limited or affected by a time-bar provision.
We advise on the contractual requirements applicable to EOT claims and the legal consequences of non-compliance.
Construction Delay Disputes
Disagreements about delay can quickly become broader construction disputes.
A contractor may claim that the principal caused delay and seek additional time and costs. A developer or owner may argue that the contractor was responsible for the delay and seek to enforce liquidated damages.
We advise on disputes involving:
-
Contractor delay
-
Principal-caused delay
-
Concurrent delay
-
Delayed approvals
-
Delayed access
-
Design delays
-
Variation-related delay
-
Subcontractor delay
-
Programme disruption
-
Extensions of time
-
Liquidated damages
-
Delay damages
-
Prolongation costs
-
Acceleration
-
Contract termination arising from delay
Where necessary, we work with relevant project records and expert evidence to assess the contractual and factual position.
Concurrent Delay
Concurrent delay can be particularly complex.
A project may experience more than one delay event during the same period, with different parties potentially responsible for different causes of delay.
For example, a contractor's progress may be affected by both:
-
A delay caused by the principal; and
-
A separate delay caused by the contractor.
The consequences depend heavily on the wording of the construction contract, the relevant legal principles and the facts of the project.
We advise on concurrent delay issues, including how competing delay events may affect:
-
Extension of time entitlement
-
Completion dates
-
Liquidated damages
-
Delay costs
-
Contractual responsibility
Liquidated Damages & Delayed Completion
Construction contracts commonly provide for liquidated damages if a contractor fails to achieve practical completion by the contractual date.
Where an extension of time is available, the relevant completion date may change.
This can make EOT entitlement particularly important.
We advise on disputes involving:
-
Liquidated damages
-
Delayed practical completion
-
Extension of time entitlement
-
Revised completion dates
-
Responsibility for delay
-
Notices and contractual time bars
-
Claims for delay-related costs
-
Defences to liquidated damages claims
For builders and contractors, an EOT claim may be important to preventing liquidated damages from being applied to a period for which the contractor is not contractually responsible.
For developers and owners, properly assessing delay entitlement is important before pursuing liquidated damages or rejecting an EOT claim.
Variations and Construction Delay
Variations can have consequences beyond the additional cost of changed work.
A variation may also affect the construction programme and give rise to an extension of time claim.
We advise on the relationship between:
-
Variations
-
Variation notices
-
Scope changes
-
Additional work
-
Programme impacts
-
EOT entitlement
-
Delay costs
-
Disruption
-
Liquidated damages
For example, where an owner instructs a significant change to the scope of work, the contractor may need to establish both its entitlement to additional payment and its entitlement to additional time.
The contract will determine how those claims must be notified, assessed and valued.
Delay, Disruption & Prolongation Costs
Not every delay claim is limited to additional time.
A prolonged project can increase the contractor's costs of remaining on site and maintaining resources.
Depending on the contract and circumstances, claims may involve:
-
Site overheads
-
Labour costs
-
Plant and equipment
-
Project management costs
-
Extended supervision
-
Accommodation and transport
-
Financing costs
-
Subcontractor costs
-
Other prolongation costs
Disruption may also affect productivity even where the contractual completion date has not necessarily been extended by the same period.
We advise on the contractual basis for delay, disruption and prolongation claims and the evidence required to support or defend them.
Delay Evidence & Construction Records
Successful delay claims are often heavily dependent on contemporaneous project records.
Relevant evidence may include:
-
Construction programmes
-
Updated programmes
-
Site diaries
-
Project correspondence
-
Notices
-
Variation records
-
Meeting minutes
-
Progress reports
-
Photographs
-
Site instructions
-
Design documentation
-
Approval records
-
Payment claims
-
Contractual notices
-
Emails and other project communications
These records can help establish what happened, when it happened, who was responsible and what effect the event had on the project.
We help clients assess the contractual significance of their project records and identify evidentiary gaps before a delay dispute escalates.

When Should You Get Legal Advice About a Construction Delay?
Early advice can be particularly valuable where:
-
A project is already behind programme
-
A contractor has submitted an EOT claim
-
An EOT claim has been rejected
-
You have received a delay notice
-
You are considering issuing a delay notice
-
A variation is affecting the programme
-
A principal is threatening liquidated damages
-
A contractor is claiming additional delay costs
-
The contract contains strict notice requirements
-
You are approaching a contractual time bar
-
Multiple causes of delay are occurring simultaneously
-
The parties disagree about responsibility for delay
-
A project is approaching practical completion
-
You are considering termination because of delay
Construction delay disputes can become significantly more difficult once contractual deadlines have passed or project records have become incomplete.
Obtaining advice early can help preserve contractual rights and establish a clear strategy.
Construction Delay Law in Victoria
Construction delay rights are primarily determined by the relevant construction contract, together with applicable legislation and legal principles.
The precise position will depend on factors including:
-
The type of construction contract
-
The parties involved
-
The contractual risk allocation
-
The cause of the delay
-
Notice requirements
-
Time-bar provisions
-
The evidence available
-
The applicable statutory framework
-
The project's circumstances
There is no universal entitlement to an extension of time simply because a project has been delayed.
The contract should be reviewed carefully to determine whether the delay event gives rise to an EOT and what procedural requirements must be satisfied.

Frequently Asked Questions
What is an extension of time in a construction contract?
An extension of time allows the contractual date for completion to be extended where the contractor has a valid contractual entitlement arising from a qualifying delay event.
What is an EOT claim?
An EOT claim is a request by a contractor for additional time to complete the works because a delay event has occurred that gives rise to an extension-of-time entitlement under the contract.
Can a builder claim an extension of time for a variation?
Potentially. A variation may affect the construction programme and may give rise to an EOT depending on the contract, the nature of the variation and the applicable notice and entitlement provisions.
What happens if an EOT claim is rejected?
The consequences depend on the contract and the circumstances. A rejected EOT may lead to disputes about the contractual completion date, liquidated damages and responsibility for delay. Legal advice should be obtained before taking further action where significant amounts are involved.
What happens if an EOT notice is late?
A late notice may affect a contractor's entitlement depending on the wording of the contract and applicable legal principles. Some contracts contain strict time bars. The precise consequences need to be assessed on the terms of the particular contract.
Can a developer claim liquidated damages for delay?
Potentially. Whether liquidated damages can be claimed depends on the contract, the applicable completion date, any valid extensions of time and the circumstances of the delay.
What is concurrent delay?
Concurrent delay generally refers to overlapping delay events involving different causes or parties during the same period. The legal consequences depend on the contract and the circumstances of the particular project.
Can you help with construction delay disputes?
Yes. Whelan Lawyers advises on EOT claims, delay responsibility, liquidated damages, variations, disruption, prolongation and related construction disputes.
