The Colorado Department of Transportation (DOT) and Intelligent Transportation Systems (ITS) are focused on the future of fiber and their infrastructure. As they plan for the future, it’s essential they know what exists today. Part of this initiative is building an Underground Utility GIS Database, which includes an assortment of tools that can support their fiber cable planning and asset management. The question was raised:

Should 3D Gyro Mapping Technology be Part of this Toolkit?

We advocated yes; then backed up our recommendation with a series of pilot projects that demonstrated the value of 3D gyroscopic mapping technology, and showcased capabilities and compliance. In order to prove this technology would be a good fit for locating and documenting Colorado’s underground assets, we mapped four representative segments:

Straight Segment with Dual Access Points
Goals: Demonstrate operational functionality of gyromapping tools and train contractors.
Critical Segment with Tighter Bends
Goals: Showcase data integration to Pointman Software.
HDD and Open Trench Pipe Segment
Goals: Illustrate detailed depth mapping at critical locations.
Pipe Segments with Single Access Point
Goals: Demo tools, process, and data where duct damage is identified.

These four mapped segments showcased the technology’s accuracy and detail accessibility. 3D XYZ profiling, bend radius analysis, as-built maps, and more proved that gyroscopic mapping technology could solve some of the challenges CDOT and ITS identified with the existing tracer wire mapping option.

Precision Mapping. Accurate Data.

One goal with 3D gyro mapping, and this project specifically, is to provide accurate and reliable as-built maps for an enriched GIS database. Additionally, it improves productivity by proactively identifying damaged ducts - which results in more successful fiber deployments.
