Evaluating Above-Ceiling Scanning in Renovation Projects

White paper
November 2025

How Rogers-O’Brien Construction compared NavVis MLX to Trimble X9 for scanning above-ceiling on a healthcare renovation project.

Renovation projects, especially in healthcare, demand accurate documentation of complex MEP systems concealed above ceilings. Traditional tripod-based laser scanning can be slow, disruptive, and costly in active facilities.

This white paper details how Rogers-O’Brien Construction used NavVis MLX and NavVis VLX 3 to scan above and below ceilings at Dell Children’s Medical Center in Austin, Texas. The team compared performance and data quality against a Trimble X9 scanner to assess both efficiency and usability for design coordination.

Readers will see how hybrid SLAM workflows helped RO capture thousands of square feet in a fraction of the time, optimize field and processing phases, and achieve measurable ROI in labor savings and client satisfaction.

What's inside?

  • Key findings: Explore how NavVis MLX and NavVis VLX 3 reduced scanning time from multiple days to just six hours—saving RO an estimated five days compared to traditional tripod workflows.

  • Hybrid approach: Learn how combining SLAM scanners with control point networks achieved both speed and precision for above- and below-ceiling environments.

  • Real-world results: See how the captured data improved MEP coordination, minimized site revisits, and allowed the project team to work efficiently within an active hospital.
