The GBRA Lake Dunlap Project involved providing a 25-acre topographic survey and boundary retracement survey on the Lake Dunlap Dam. The project site conditions varied from dense tree cover, open grass area, canal, existing river and over 100-year-old dam. To successfully complete this project, CEC utilized many different data collection formats to ensure we gather highly detailed field data, while keeping our crews safe. The process involved utilizing RTK GPS, Robotic Total Stations and Terrestrial Scanners to safely obtain our objective. The terrestrial scanner allowed us to safely gather a dense and highly accurate point cloud on the existing conditions of the dam. This work was performed in a manner that did not require any of our staff go out onto the dam physically. The boundary survey included recovering existing monumentation, analyzing and retracing multiple deeds and plats, some of which dated back over 100 years.
The data was processed and verified thru CEC’s rigorous QA/QC process to ensure the data we provided is accurate. The point cloud and conventional survey data was merged and then used to prepare a topographic CAD drawing, Retracement Plat and a point cloud of the existing dam conditions were delivered to the client. The point cloud was utilized by professionals to accurately create plans to repair the almost 100-year-old structure.
