Who This Serves

For attorneys who need
a defensible P6 expert

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.

When claims reach the courtroom,
methodology matters.

Transit projects, acute care hospitals, and major infrastructure programs involve schedule complexity that separates genuine P6 experts from general project managers. When opposing counsel reviews your expert’s credentials and methodology, that difference decides the case.
