Case Study: Zengun saves 1.5 months in review time and streamlines site collaboration with Bluebeam Software, Inc.

Zengun Bluebeam Revu Overcomes the Challenges of a Classic Stockholm Building

Zengun, a 220‑employee Stockholm contractor specializing in complex renovations, faced delays and cost risk on its landmark Torsgatan office conversion due to slow, paper‑based review cycles, fragmented communication between site teams and consultants, and legacy drawings that didn’t match reality. These issues led to incorrect measurements, rework and safety concerns that threatened schedule and budget.

By adopting Bluebeam Revu/Studio as a single collaboration platform and digitizing drawings and scans, Zengun centralized communication, enabled real‑time markup and streamlined reviews. The change cut planning review time by about 1.5 months, reduced meetings and rework, improved document control and site safety, and freed supervisors to spend more time on site.
