Surveying and Mapping. <strong>Chapter</strong> 5 covers the surveying and mapping information the designer canexpect to receive. Ideally the design, survey, geotechnical and conceptual study engineers and the owneragency review the proposed work on the ground and determine the information and limits of the surveyrequired to complete the project.When field reviews are not possible, it is still beneficial for the designer and survey and mapping/locationengineer to discuss the field information required. In many cases the designer's experience with newconstruction, reconstruction, and RRR projects can increase the effectiveness of the survey crew.At some point in the project development process the designer usually provides the appropriate surveyunit with the information to stake the project in the field. This could include notes to establish centerline,set slope stakes, clearing limits, reference points, right-of-way, and other control points necessary tocomplete the work. The designer shall keep the design files purged so the information provided for thestakeouts is current, correct, and reflects the design criteria established for the project. All notes preparedfor field use will require checking to prevent the possibility of providing incorrect data.9 - 11
