Introduction

In construction projects, completing the work within the contractual time is extremely important.

But what happens when the project is delayed because of events that are not the contractor’s responsibility?

For example:

  • The employer delays drawings.
  • The site is handed over late.
  • There are major design changes.
  • Unexpected site conditions are encountered.
  • Materials that the employer is responsible for are delivered late.

In such situations, the contractor may be entitled to an Extension of Time, commonly known as EOT.

In this video, we will understand what an EOT claim is, common reasons for EOT, and the seven basic steps for preparing and submitting an EOT claim.


What Is an EOT Claim?

An Extension of Time claim is a formal request by a contractor to extend a contractual milestone or completion date because of a delay event for which the contractor has contractual entitlement.

For example:

Suppose a project has a contractual completion period of 24 months.

If an employer-caused delay affects completion by two months, the contractor may seek an EOT of two months, subject to the contract and evidence.

But there is an important point:

Every delay does not automatically give the contractor a right to EOT.

The contractor must establish that:

The event is covered by the contract + it caused delay + the delay affected the relevant completion date.


Common Reasons for EOT Claims

Some common causes include:

1. Design Changes

The employer changes the design or specifications, requiring additional work or time.

2. Late Drawings or Approvals

Construction cannot proceed because required drawings or approvals are delayed.

3. Late Site Access

The contractor cannot start or continue work because the required work area is not available.

4. Unforeseen Site Conditions

Unexpected rock, groundwater, contaminated soil, or underground utilities may affect construction.

5. Adverse Weather

Exceptional weather events may cause delay, depending on the contractual risk allocation.

6. Delayed Material or Equipment

Materials or equipment that another party is responsible for may arrive late.

7. Regulatory or Permit Delays

Approvals or permits required for the project may be delayed.

However, whether any of these events actually entitles the contractor to EOT depends on the specific contract provisions and circumstances.


The 7 Steps for an EOT Claim

A simple way to remember the process is:

Review → Identify → Notify → Analyse → Prepare → Submit → Resolve

Let’s understand these seven steps.


Step 1 – Review the Contract

Before making an EOT claim, carefully review the contract.

Look for clauses dealing with:

  • Extension of Time
  • Delay
  • Notice
  • Variations
  • Employer’s risks
  • Exceptional events
  • Completion dates
  • Liquidated damages

Also check whether the contract specifies a particular time period for giving notice.

This is important because some contracts contain conditions precedent or time-bar provisions.

So the first question should always be:

What does my contract actually say?


Step 2 – Identify the Grounds for the Claim

Next, identify the event that caused or may cause delay.

For example:

“The employer was required to provide the revised structural drawings by 1 June, but the drawings were received on 1 July.”

Now identify:

  • What happened?
  • When did it happen?
  • Who was responsible?
  • Which contract clause applies?
  • What work was affected?

At this stage, start collecting supporting evidence.


Step 3 – Notify the Employer

This is one of the most important steps.

If a delay event occurs, the contractor should give the required Notice of Delay or Notice of Claim within the period specified by the contract.

The notice should normally explain:

  • The delay event
  • Date of occurrence
  • Relevant contract provision
  • Potential impact
  • Potential EOT requirement

Many modern contracts also contain early-warning mechanisms, allowing potential problems to be identified before they become major delays.

The important lesson is:

Don’t wait until the project is already delayed by several months before giving notice.

Follow the contract’s notice requirements.


Step 4 – Assess the Impact

Now comes the technical part.

The contractor must establish:

Did the event actually delay the project?

It is not enough to say:

“The drawing was delayed by 30 days.”

The important question is:

“Did that 30-day delay actually delay project completion?”

This is where the critical path becomes important.

The contractor may need to examine:

  • Baseline programme
  • Updated programmes
  • Actual progress
  • Critical activities
  • Available float
  • Concurrent delays
  • Sequence of work

Depending on the complexity of the dispute, different delay-analysis methods may be used.


Step 5 – Prepare the EOT Claim

Once entitlement and impact have been analysed, prepare the formal EOT submission.

A good EOT claim should clearly explain:

Event

What happened?

Contractual entitlement

Which clause provides the right to EOT?

Cause

Who or what caused the delay?

Effect

How did the event affect the programme?

Duration

How many additional days are being claimed?

Evidence

What documents support the claim?

Supporting documents may include:

  • Notices
  • Correspondence
  • Site reports
  • Photographs
  • Drawings
  • Instructions
  • Meeting minutes
  • Programmes
  • Expert reports

A well-organised claim makes the assessment process much easier.


Step 6 – Submit and Follow Up

Submit the claim according to the contractual procedure.

Keep a record of:

  • Submission date
  • Documents submitted
  • Responses received
  • Additional information requested
  • Revised submissions

For an ongoing delay, the contractor may also need to provide updated or interim particulars rather than waiting until the event is completely over, depending on the contract.

So EOT claims should be treated as a live contract-management process, not simply a document prepared at the end of the project.


Step 7 – Negotiation and Resolution

After submission, the employer, engineer, contract administrator, or other designated party will assess the claim according to the contract.

The parties may agree on:

  • Full EOT
  • Partial EOT
  • No EOT
  • Further analysis or information

If the parties cannot agree, the matter may proceed through the contract’s dispute-resolution mechanism, potentially leading to adjudication, dispute boards, arbitration, or litigation, depending on the contract and applicable law.


Practical Example

Let’s take a simple example.

A contractor is constructing a bridge.

According to the approved programme, foundation work is scheduled to begin on 1 April.

The contractor needs an important design drawing from the employer.

The drawing should have been provided by 15 March, but it is received on 15 April.

So there is a one-month delay in receiving the drawing.

Can the contractor automatically claim 30 days EOT?

Not necessarily.

We need to ask:

First: Does the contract provide EOT for this type of employer-caused delay?

Second: Did the contractor give the required notice?

Third: Was the affected foundation work on the critical path?

Fourth: Could the contractor have carried out other work during this period?

Fifth: Was there any concurrent contractor-caused delay?

Sixth: What was the actual effect on the contractual completion date?

Only after answering these questions can the EOT entitlement be properly assessed.


EOT and Delay Costs

Another important distinction is between time entitlement and financial entitlement.

A contractor may be entitled to additional time without necessarily being entitled to additional compensation.

For example, a particular event may be classified under the contract as an excusable delay but not a compensable delay.

Therefore, always check separately:

Am I entitled to time?

and

Am I entitled to money?

The answer depends on the contract and applicable law.

If additional time causes prolongation costs—such as extended site staff, equipment, accommodation, or site overheads—those costs should be separately identified and supported where the contract allows recovery.


Concurrent Delay

One of the most complicated EOT issues is concurrent delay.

Suppose the employer causes a 30-day delay.

But during the same period, the contractor also has a 30-day delay caused by inadequate resources.

Now the question becomes:

Who is responsible for the delay to completion?

The answer can depend on the contract, applicable law, facts, and the particular delay-analysis approach used.

Therefore, concurrent delay should be carefully analysed rather than simply assuming that every employer delay results in an equivalent EOT.


Key Documents for an EOT Claim

A contractor should maintain:

1. Contract and relevant clauses

2. Baseline programme

3. Updated programmes

4. Delay notices

5. Correspondence

6. Site diaries and daily reports

7. Drawings and instructions

8. Photographs

9. Meeting minutes

10. Delay analysis

These records create the evidence trail connecting:

Event → Cause → Delay → Impact → EOT


Final Takeaway

An EOT claim is much more than saying:

“The project was delayed, so give me more time.”

A strong EOT claim demonstrates:

Contractual entitlement + Proper notice + Evidence + Causation + Programme impact

Remember the seven steps:

1. Review the Contract

2. Identify the Grounds

3. Notify

4. Assess the Impact

5. Prepare the Claim

6. Submit and Follow Up

7. Negotiate and Resolve

And the most important lesson is:

A delay event does not automatically equal an Extension of Time. You must demonstrate how that event affected the contractual completion date.

Good contract administration, timely notices, reliable programmes, and proper contemporary records are therefore the foundation of a successful EOT claim.
