Nebraska Public Power District - Electric Transmission Reliability Project


The Challenge: 
The Nebraska Public Power District (NPPD) wanted to enhance service reliability across the state. POWER Engineers needed a dedicated survey team to take on the project, and our Survey department was called in.  

The Solution: 
Our team checked published horizontal and vertical control points using Trimble GPS equipment and the Seiler Instrument VRS Network and utilized the North American Datum of 1983 (NAD83), Nebraska State Plane Coordinate System, and the North American Vertical Datum of 1988 (NAVD88). All subsequent surveys for the project were made using Seiler’s VRS Network. After some research, our survey crews recovered all existing public land system corners, and other property corners as required to define the ownership areas along the route. We also performed ground surveys to determine the locations of physical features that would affect the design and placement of the transmission line structures such as irrigation pivots, wells, buildings, underground and above ground utilities.  

Project Benefits: 
To help continue the project process, we have begun the preparation of access maps and easement acquisition plats complete with legal descriptions for the new easement areas. And we will also perform the construction staking for the placement of all the transmission line structures. NPPD can move forward with their service reliability enhancement project on solid foundation, knowing that the surveys conducted were done accurately and with great attention to detail.
