The Situation

Percheron was engaged to document an existing open trench to support the installation of a new 4-inch pipeline. The trench contained multiple existing utilities with no reliable as-built documentation, creating a high risk of utility conflicts during design and construction.

The project area included approximately 100,000 square feet of coverage and 1,300 linear feet of trench corridor requiring detailed spatial documentation. The client needed a fast, accurate solution to capture existing conditions and support critical engineering decisions under tight timelines.

The Strategy

Percheron deployed a wearable mobile laser scanning system to rapidly capture comprehensive spatial and visual data across the trench corridor. This approach allowed for continuous, on-foot scanning of the full 1,300-linear-foot alignment without the need for static scan setups.

Simultaneous 360° panoramic imagery was captured alongside the point cloud data, providing both visual context and precise measurements. The data was processed through an accelerated workflow to produce a fully registered, high-resolution digital representation of the trench and existing utilities.

Deliverables included a registered point cloud, georeferenced panoramic imagery, and a web-based visualization platform that enabled remote access and measurement-based analysis for the client’s engineering team.

The Success

Field data capture was completed in a matter of hours, with full deliverables provided within 48 hours—significantly reducing both field time and processing duration compared to traditional terrestrial scanning methods.

The resulting digital dataset allowed for clear identification of existing utilities, improved routing confidence for the new pipeline, and minimized the risk of utility conflicts, rework, and potential field issues. The project demonstrated Percheron’s ability to deliver fast, accurate, and actionable data solutions for complex infrastructure environments.
