Sewer Data Collection - Town of Addis, LA

Es² collected spatial and attribute data for the Town of Addis, LA sanitary sewer system.  A Trimble R2 GNSS receiver was utilized with a VRS network to obtain the top of manhole location and elevation.  Pipe invert elevations and diameters were collected using a survey rod with Pipe-Mic attachment.  Geospatial and attribute data were stored in the Trimble Slate data collector.  Once complete, the data was published to the Town's enterprise GIS for inclusion in web and mobile apps.


Wharf Infrastructure Assets - Port of New Orleans, LA

In order to obtain data for inclusion in an enterprise GIS, Es² utilized our Trimble R2 RTK network rover and Trimble T10 tablet for asset location.  Esri Collector for ArcGIS was installed on the T10 tablet and configured for offline data collection.  Es² obtained the location and attributes of hundreds of assets along the Port of New Orleans waterfront.

Construction Stakeout - US Army Corps of Engineers

As a subcontractor to Trex Services, Inc., Es² provided construction stakeout services for the US Army Corps of Engineers on the Comite Diversion project near Baton Rouge, LA.  Es² utilized our Trimble S5 robotic total station with active-track MT-1000 prism and R2 RTK receiver to stake out the clearing boundaries.


LOOP Environmental Monitoring - Port Fourchon, LA

The objective of this study was to monitor the onshore component of the EMP, specifically the marsh and beach systems. The EMP is
designed to determine if the LOOP facility and pipeline adversely impact surrounding wetland plant and wildlife communities because of the construction (1978 – 1981) and operation (ongoing since 1982) of the project. The scope of this project includes beach elevation ground surveys, beach vegetation surveys, and a land loss and habitat change survey.
