Time Impact Analysis (TIA)

Time Impact Analysis (TIA) is the industry-standard method for prospective and retrospective delay analysis on construction and infrastructure projects. Our Time Impact Analysis services provide rigorous, defensible analysis of delay events and their impact on project schedules. We combine advanced scheduling expertise with commercial acumen to deliver TIA that supports extension of time claims, dispute resolution, and commercial negotiations.

What We Do

Prospective Time Impact Analysis

Conduct forward-looking TIA to assess the anticipated impact of delay events on project completion. We insert delay events into the current accepted programme, model their impact on the critical path, and quantify the expected extension of time entitlement. We support proactive EOT claims and early commercial resolution.

Retrospective Time Impact Analysis

Conduct retrospective TIA to assess the actual impact of delay events on project completion. We reconstruct the project schedule at the time of each delay event, model the impact, and quantify the extension of time entitlement. We support post-completion claims and dispute resolution.

Baseline & Programme Assessment

Assess the quality and suitability of baseline programmes for use in TIA. We review programme logic, resource loading, and critical path integrity. We identify programme deficiencies and recommend corrections to ensure the baseline is a reliable foundation for delay analysis.

Delay Event Fragnet Development

Develop delay event fragnets for insertion into project programmes. We model each delay event as a discrete schedule fragment, define its logic relationships, and insert it into the programme at the appropriate point in time. We ensure fragnets accurately represent the delay and its consequences.

Critical Path & Float Analysis

Analyse critical path and float consumption to determine the impact of delay events on project completion. We identify which activities are on the critical path at the time of each delay, assess float availability, and determine whether delays extend the critical path and project completion date.

TIA Reporting & Expert Support

Prepare comprehensive TIA reports suitable for EOT claims, adjudication, and arbitration. We document methodology, assumptions, and findings clearly. We respond to challenges from opposing experts and provide expert witness testimony to support dispute resolution proceedings.

Who We Are

Our Time Impact Analysis team brings deep expertise in delay analysis, schedule management, and dispute resolution across infrastructure, transport, rail, and construction projects. We are experienced Primavera P6 practitioners with a thorough understanding of TIA methodology, industry protocols, and the Society of Construction Law (SCL) Delay and Disruption Protocol. We’ve conducted TIA in support of EOT claims, adjudication proceedings, and arbitration cases, and understand what it takes to produce analysis that withstands scrutiny.

TIA Methodology

Time Impact Analysis is a recognised delay analysis methodology that models the impact of individual delay events on a project schedule. Our TIA follows a structured, transparent process:

Programme Validation

We validate the baseline or accepted programme to confirm it is a reliable foundation for analysis. We check programme logic, critical path integrity, and resource loading. We identify and document any programme deficiencies that may affect the analysis.

Delay Event Identification

We identify and document each delay event to be analysed. We establish the nature, timing, and duration of each event from project records, correspondence, and contemporaneous documentation. We build a clear factual record for each delay.

Fragnet Development & Insertion

We develop a fragnet for each delay event and insert it into the programme at the point in time when the delay occurred. We define logic relationships between the fragnet and existing programme activities to accurately model the delay’s consequences.

Impact Quantification

We run the updated programme to determine the impact of each delay event on the critical path and project completion date. We quantify the extension of time attributable to each delay event and document the cumulative impact of all delay events.

Concurrent Delay Assessment

We assess whether concurrent delays exist and how they affect entitlements. We identify delays occurring simultaneously, determine whether they are independent or interdependent, and assess how concurrent delay affects EOT entitlements under the contract.

Reporting & Documentation

We prepare comprehensive TIA reports documenting methodology, assumptions, findings, and conclusions. We present results clearly and support them with schedule extracts, programme outputs, and contemporaneous evidence. Reports are prepared to withstand expert scrutiny.

Our Approach

Programme Validation – We begin by validating the baseline or accepted programme to confirm it is a reliable foundation for TIA. We check logic, critical path integrity, and resource loading, and document any deficiencies.
Delay Event Documentation – We identify and document each delay event from project records, correspondence, and contemporaneous documentation. We establish the nature, timing, and duration of each delay and build a clear factual record.
Fragnet Development – We develop a fragnet for each delay event and insert it into the programme at the appropriate point in time. We define logic relationships to accurately model the delay’s consequences on the schedule.
Impact Analysis – We run the updated programme to quantify the impact of each delay on the critical path and project completion date. We assess concurrent delays and their effect on EOT entitlements.
Reporting – We prepare comprehensive TIA reports documenting methodology, assumptions, findings, and conclusions. We present results clearly and support them with schedule extracts and contemporaneous evidence.
Dispute Support – We respond to challenges from opposing experts, prepare rebuttal analysis, and provide expert witness testimony in adjudication and arbitration proceedings.
