CPM Pros provides forensic schedule analysis and expert witness testimony in Primavera P6 for construction delay disputes, retained by owners, general contractors, trade contractors, sureties and their counsel. Primavera P6 forensic schedule analysis for construction litigation: XER reconstruction, as-built critical path, delay causation opinions, and expert witness testimony for arbitration, mediation, or trial.
Construction litigation needs a scheduling expert who can read an XER file, trace 50 schedule updates, and explain critical path methodology to a judge in plain English. CPM Pros brings that exact skill set to the delay claims, forensic analyses, and expert witness engagements where it is needed most. General contractors and trade contractors pursuing a time extension or REA before a dispute is filed start with TIA and delay claim support.
Forensic schedule analysis is only as strong as the files behind it. CPM Pros works from the native Primavera P6 XER files, classifies the method under AACE RP 29R-03, and writes the report so that counsel can defend every step of it under cross-examination.
Yes. Many engagements start with a consulting role while counsel evaluates the claim, and consulting-expert work is generally handled as attorney work product. If the matter proceeds, the same analyst can be designated to testify and the report is prepared for disclosure. Counsel decides when and whether that designation happens.
Every native XER (or XML) file from the baseline through the final update, the approved baseline narrative, change order and RFI logs, daily reports, meeting minutes, and the correspondence that gave notice of delay. PDF Gantt charts alone cannot support a rebuilt critical path. Missing updates are recorded as a limitation of the analysis, not filled in by assumption.
The one the project record supports. A complete chain of contemporaneous updates favors a windows analysis; a disputed event on a sound baseline favors a time impact analysis; a completed project with a reliable as-built can support a collapsed as-built. The report names the method, its AACE RP 29R-03 classification, and the reasons the alternatives were not used.
It depends on the number of updates and the condition of the files. A single-phase project with a clean update chain can be analyzed in a few weeks. A multi-year program with fifty or more updates and a contested baseline takes longer. A written scope, delivery dates, and a firm quote come before any work starts, typically within 3 business days of receiving the file inventory.
Yes. Deposition, arbitration hearing, and trial testimony are part of the service, along with rebuttal reports. Expert reports follow the structure the forum requires, including the opinions, their basis, the materials considered, exhibits, qualifications, and prior testimony expected in a Rule 26(a)(2)(B) report in federal matters.
Expert reports built from the native P6 files, with the method named under AACE RP 29R-03 and the files produced so the work can be checked.
Whether you need a baseline developed, a delay analyzed, or an independent schedule review, we’re ready to engage. Scheduling is the only thing on our calendar.
