Construction Delay Analysis & EOT Claims Support

Technical schedule analysis that helps you understand what caused a delay and document your position clearly.

What we do

When a project finishes late, the first question is what happened and when. We analyze the schedules, progress records and project events to show how delays affected the critical path and the completion date.

We choose the method to suit the contract and the quality of the records, then present the results in a report that your project team, management and advisers can follow. An extension of time (EOT) is also known as a time extension request or time extension claim; we prepare the technical schedule support behind it.

Variance provides technical schedule analysis and claims support. We do not provide legal advice or expert witness testimony.

What is included

Forensic schedule analysis

Structured review of baseline, updates and as-built data to reconstruct what happened on the critical path.

Time impact analysis (TIA)

Fragnet-based analysis of how a specific event affected or is expected to affect the completion date.

Windows analysis

Period-by-period analysis that tracks the critical path and delay through the life of the project.

As-planned vs. as-built comparison

Side-by-side comparison of the plan and the actual sequence, durations and milestones.

Concurrent delay assessment

Review of overlapping events and how they interact on the critical path.

Critical path and float analysis

Identification of driving paths, float use and changes in criticality across updates.

Claim technical preparation

Technical content, exhibits and schedule models prepared for the claim or submission your team is assembling.

Time extension (EOT) documentation

Notices, chronologies and supporting schedule documentation organized for an extension of time (time extension request) submission.

What you receive

  • Delay analysis report with method and findings
  • Event and impact chronology
  • Schedule models and supporting files
  • Charts, tables and exhibits
  • Narrative explaining the methodology and assumptions
  • Supporting schedule documentation for EOT submissions

Why it matters

A clear account of events

A single chronology ties delays to the records that support them.

A method that fits the records

We match the analysis method to the contract and the data available.

Exhibits people can read

Plain charts and tables make the analysis easier to follow for non-schedulers.

Early, organized records

Capturing the schedule impact as events happen makes later submissions simpler.

How it works

  1. Review contract and records

    We review the time provisions, schedules, progress records and correspondence you provide.

  2. Analyze schedules and events

    We build the analysis using the method agreed with you and test the results.

  3. Report the findings

    You receive a report, exhibits and working files your team can use.

Delivered remotely: files, calls and screen-share reviews keep the work moving with teams anywhere in the United States, with no site visit needed for this service.
