The Role of Expert Advisory in Delay & EOT Claims

What Is an EOT Claim and Why Does Delay Matter in Construction Projects?

In the construction industry, delays are an almost inevitable occurrence. Whether due to weather events, changes in scope, site access issues, or supply chain disruptions, the impact of such delays can be substantial—both financially and operationally. Extension of Time (EOT) claims serve as a contractual mechanism allowing a contractor additional time to complete the works when delays are outside of their control. However, substantiating such claims can be complex, and this is where expert advisory plays a pivotal role.

EOT claims often require thorough documentation, logical analysis, and a solid understanding of both contract law and construction programming. When mishandled, these claims can spiral into costly disputes. Engaging independent expert advisors can be the determining factor in resolving such claims efficiently and fairly.

How Do Expert Advisors Add Value to Delay and EOT Claims?

Expert advisors bring technical knowledge, legal understanding, and impartiality to the table. They assess claims against contractual entitlements, provide objective analysis of schedules, and deliver detailed reports that often become key pieces of evidence in dispute resolution.

Key attributes of expert advisory in delay and EOT claims:

Objective Assessment – Independent review with no stakeholder bias
Technical Expertise – Skilled in scheduling, CPM (Critical Path Method), and delay forensics
Methodological Approach – Applies structured and recognised delay analysis techniques
Causal Link Establishment – Clearly identifies how specific events affect the project timeline
Communication Skills – Translates complex findings into understandable reports for all stakeholders

What Are the Most Common Delay Analysis Methods Used?

There are several industry-recognised methodologies used by expert advisors to analyse delay claims. These methodologies are selected based on the availability of project data, the stage of the project, and the type of contract in use.

Widely used methods include:

Time Impact Analysis (TIA) – Incorporates new delays into the baseline programme to assess time impact.
As-Planned vs As-Built – Compares the original schedule with actual progress to identify variances.
Windows Analysis – Reviews progress and delays over specific time periods.
Collapsed As-Built (But-for Analysis) – Determines the duration the project would have taken without the delay events.

Why Is Independent Advisory More Effective Than Internal Handling?

Often, project managers and in-house teams lack the neutrality and detailed methodological understanding required to resolve complex delay claims. Expert advisors offer a more structured, credible, and contractually sound approach.

Comparison Table: Internal Project Team vs Expert Advisory

Aspect	Internal Project Team	Expert Advisory
Bias Risk	High	Low – Objective and independent
Technical Delay Analysis	Moderate	Comprehensive and methodologically sound
Legal & Contractual Insight	Basic	Advanced understanding of entitlements
Value in Dispute Resolution	Moderate	High – Often decisive in outcome
Methodological Rigor	Varies	Follows industry standards
Documentation & Reporting	Project-focused	Tribunal-quality expert reports

What Are the Critical Tasks Carried Out by Expert Advisors?

Expert advisors perform a wide range of tasks tailored to the needs of the specific project and claim.

Core responsibilities may include:

Assessing construction schedules (baseline, revised, and as-built)
Identifying and quantifying delay events
Applying delay analysis methodologies recognised by the courts
Determining whether delays are excusable, compensable, or concurrent
Supporting negotiation or settlement processes with expert evidence
Preparing detailed written reports or rebuttals for arbitration or adjudication
Offering witness testimony where required

What Types of Evidence Do Experts Evaluate in Delay Claims?

To build a defensible and structured claim, expert advisors review a wide range of documents and project artefacts.

Commonly reviewed evidence includes:

Baseline and revised programmes
Site diaries and progress reports
Meeting minutes
Variation logs and change order records
Subcontractor correspondence
Photos and delivery receipts
Communication logs

This documentation helps build a narrative and causal chain between events and project delays, which is crucial in securing or rejecting an EOT claim.

What Role Do Expert Advisors Play in Dispute Resolution?

In disputes arising from delay claims, expert advisors are often called upon to provide evidence through written reports or oral testimony. Their expertise and impartiality give their opinions considerable weight in adjudication, arbitration, and litigation proceedings.

In alternative dispute resolution (ADR) settings such as mediation or expert determination, they offer neutral, informed insight that helps both parties understand their positions more clearly. This often facilitates quicker settlements and avoids prolonged disputes.

When Should a Contractor Engage an Expert Advisor?

Engaging expert advisory services early—before a claim is formally submitted—can strengthen the quality and credibility of the claim. However, even when a dispute is already underway, expert advisors can assist in salvaging poorly documented or structured claims by introducing methodical rigour and objectivity.

Indicators you may need expert assistance:

Disagreement over the critical path or cause of delay
Multiple concurrent delays complicating the analysis
Lack of in-house scheduling expertise
Escalation to dispute or arbitration proceedings
Requirement for a third-party, independent report

Frequently Asked Questions

1. What is the purpose of an EOT claim in construction contracts?
An EOT (Extension of Time) claim allows a contractor to request additional time to complete a project due to delays outside their control, preventing liquidated damages.
2. Can expert advisors determine who is responsible for the delay?
Yes, expert advisors apply structured analysis to identify whether delays are the responsibility of the contractor, client, or shared (concurrent delays).
3. What documents are crucial for preparing a strong delay claim?
Key documents include baseline programmes, site diaries, correspondence logs, variation orders, and as-built schedules.
4. Are expert advisors involved only in legal disputes?
No. While they often participate in formal disputes, advisors are also engaged to help avoid escalation by providing early, credible input.
5. How do expert advisors evaluate the impact of concurrent delays?
They use analytical methods like Time Impact Analysis or Windows Analysis to assess how overlapping delays affect the project’s critical path.
6. Is expert advisory only needed for large projects?
No. Regardless of size, any project facing time-related disputes can benefit from expert advisory, especially where delays could impact entitlements or lead to financial penalties.
