bowmanconsulting.com Whidden Surveying & Mapping, Inc. (WSM) was assigned this task as part of the Indefinite Delivery Contract with the US Army Corps of Engineers. This survey required data to be collected to provide 66 beach profiles. Profile lines were extended 150-feet landward and extended sea- ward from the most landward offshore data point a distance of no less than 3,000 feet. Spot elevations were collected on 10-foot ranges with all breaks in grade greater than 1-foot vertically, and recorded for all monuments recovered in good condition. Soundings were performed at 12.5-foot ranges along the profile. RTK was utilized for horizontal and vertical positioning of all hydrographic data acquisi- tion. All data was collected during acceptable sea conditions. Structures along each survey profile were located along with above ground utility indicators. The maximum allowable distance between topographic and hydrographic data points was 25 feet. Motion sensing compensation (Heave, Pitch, Roll) was used for all data acquired with a Teledyne (DMS 10). Barchecks were completed at the beginning and end of every field day. Positions were referenced to NAD 1983. Elevations were referenced to NAVD 1988. For all Real Time Kinematic surveys, the base station only occupied NGS monuments. FDEP monuments are not acceptable. WSM provided weekly progress reports containing information on daily site work, manpower scheduling and all required final delivera- bles in the required formats including ASCII files, metadata, field books, GPS network plans, Quality control report, and survey reports (digital and hard copy).
