Case Study: Suburban Consulting Engineers, Inc. achieves fast, high‑accuracy gas pipeline mapping with Trimble

How GNSS speeds work to map and document gas pipeline assets

Suburban Consulting Engineers, Inc. (SCE), a leading civil and municipal engineering firm working with gas utilities in Georgia, faced the challenge of rapidly capturing high-volume, traceable location and attribute data for thousands of miles of new and existing pipelines — often before lines were buried and under difficult field conditions — while meeting PHMSA and client reporting requirements.

SCE implemented Trimble R2 GNSS receivers, Trimble TDC600 handhelds with Trimble VRS corrections and Esri ArcGIS Collector plus custom data‑collection forms and QA workflows. The result is centimeter‑level accuracy, faster collection and one‑day GIS integration, weekly digital‑twin updates, fewer required client GIS staff, and rapid field queries (one example: seven matching pipe segments found in five minutes), delivering fully traceable, regulatory‑compliant asset records and reduced manhours.
