Coordinate and Perform Topographical Survey. This task includes providing design survey services within the topographic survey limits shown in Exhibit No. 1 as the North Drainage Area and the South Drainage Area, to support the design team for this project. Work items associated with this task include the following: The ground survey area is approximately 6 acres. Preparation of a survey plan that will determine the appropriate survey methods and equipment to be utilized. It is assumed that the Primary Airport Control Station (PACS) and Secondary Airport Control Stations (SACS) located on the airport are in good condition and can be verified; however, if it is found that the PACS and SACS are compromised, establishment of temporary airport control must be completed and tied to the national spatial reference system via static GPS observations. Ground topography of non-pavement areas will be surveyed at 50-foot stations with associated cross sections having no greater than 50-foot spacing and will include additional shots as necessary to accurately depict breaklines. These ground topography areas will be surveyed with vertical accuracies not to exceed +\- 0.10 feet. Other elements that will be located include if within the survey area are guidance signs, taxiway and apron lighting and markings, NAVAIDS within the project area (if any), fuel farm, fences, gates and other airport features as required. During design, there may be the need to verify other existing survey information or extend the limits of the existing survey. Reduce all field notes and pictures into a topographic survey report to be used by the Engineer. Create an AutoCAD drawing using the surveyed data that will include symbols, linework, breaklines, notes, details and a surface model.
