Full profile

Expert evidence in US construction disputes

Delay disputes on federal contracts go to the boards of contract appeals or the Court of Federal Claims under the Contract Disputes Act. State, municipal and private disputes go to state or federal court or to arbitration, often under AAA construction rules. In federal court, Federal Rule of Evidence 702 requires the expert’s opinion to rest on sufficient facts and a reliable method, reliably applied.

How we can help

  • Testifying delay expert: expert report, rebuttal report, deposition and testimony
  • Consulting expert to counsel, testing the case before an expert is disclosed
  • Rebuttal of the opposing schedule analysis: method, updates, records and calculations
  • Forensic schedule analysis following AACE Recommended Practice 29R-03
  • Delay and disruption support to the quantum expert

A method that survives challenge

We choose the method that suits the records and explain why, document every assumption, and give counsel files the other side can reproduce. That is what holds up under cross-examination and reliability challenges.

Your first conversation

What we cover

A free 30-minute call. We look at the forum and schedule, the contract and claims in issue, the state of the schedule records, and whether experts have been disclosed.

What to share first

A short description and your next deadline are enough. If you like, name the forum and the next deadline in the case schedule. You do not need to send contract documents before the call.

Scope and fee

After the call we agree which documents we need. Once we have reviewed them, we confirm the scope and fee in writing before any work starts.

Send a short brief

No meeting needed. Give us your work email and two sentences about the issue. Please do not attach contract documents at this stage.






    Ahmed Elsayed replies within 1 working day (Monday to Friday, US Eastern time). Your brief goes only to the Solvix sales inbox. If we go on to work together, we sign an NDA and then send you a private shared folder for the contract documents.

    Most disputes start as a rejected REA or time extension. See REA and delay claims and time impact analysis.
