NAVFAC Mid-Atlantic partnered with Clark Nexsen’s Geospatial Information Systems (GIS) team to standardize and consolidate data on more than 90,000 utility features previously maintained at separate installations across multiple formats.
Spanning 13 installations from Maine to Virginia, the preliminary data collection effort began at each installation through meetings with utilities staff, the Navy’s GeoReadiness Center (GRC) staff, and various stakeholders including public works, planning, security, and safety offices. Preliminary databases were created for each facility, leveraging government-provided support data (GIS schema, imagery, existing GIS data, hard copy as-built drawings, etc.), and an installation-specific work plan and safety plan were developed. Unique safety and security requirements were also addressed at each facility.
With facilities ranging from naval shipyards to weapons stations to hospitals and more, this was a large-scale field data collection effort that needed to be accomplished within a compressed time frame. Working in teams of up to 24 personnel, Clark Nexsen experts utilized our transdisciplinary practice to maximize data collection efficiency, with field trips featuring teams of specialists such as electrical, civil, and mechanical engineers paired with a GPS technician. This integrated approach enabled the use of network-based Real-Time Kinematic (RTK) survey-grade GPS equipment to conduct a full, accurate location and attribution of utilities. Data and geotagged digital photography were uploaded daily via the cloud for accelerated data development in the office.
Through close coordination with local and regional staff, our field teams were able to fully capture each utility system and reconcile data gaps noted during initial meetings and data collection. Simultaneously, database development took place in the office, enabling a quick turnaround of data deliverables to the Navy as a result of this innovative, forward-thinking work strategy.
The final deliverable included geospatial information on more than 90,000 utility features, fully integrated with the GeoReadiness Center’s GIS Database and across multiple government databases, as well as individual geodatabases for each installation with up-to-date, accurate GPS and GIS information.
