Case Study: Hensel Phelps achieves 75% faster inspections and paperless quality control with Trimble Prolog Mobile

Hensel Phelps Puts Mobile Technology to the Quality Test

Hensel Phelps faced a $190M fast‑track design‑build in the U.S. Northeast—three buildings across a 62‑acre site with an aggressive two‑year schedule—and needed to streamline quality control and inspections that had relied on carrying paper drawings and manual punchlists. Limited onsite connectivity and the scale of the site made immediate access to current documents and clear location tracking critical to meeting deadlines.

The team deployed Prolog Mobile on nine iPad Minis (shared with four subcontractors), using features like offline sync, checklists and plan‑view location pins to capture photos, update items in real time and centralize records. The digital workflow cut inspection time by an estimated 75%, sped punchlist resolution, reduced paper use, helped the project finish months ahead of schedule, and is now being rolled out to other projects.
