71/91 Interchange Project
A Complex Transportation Infrastructure Project
Challenge
The SR‑71 / SR‑91 Interchange in Riverside County, California is a complex freeway reconstruction performed under staged construction and live traffic conditions. As the project neared completion, the owner retained CMC Project Solutions to independently evaluate the contractor’s Primavera P6 schedule and assess potential delay exposure.

Quantified schedule impacts related to differing site conditions, environmental work restrictions, and railroad moratoriums. - Claim Support
Evaluated the contractor’s $5.9M delay claim through targeted variance analysis and forensic schedule review. - Risk Visibility
Provided real‑time insight into completion risk to support owner decision‑making during project closeout.
