❑ 0) Insurance statement in 1/4" high letters "The survey depicted here is not covered by professional liability insurance" if there is no professional liability insurance. ❑ (k) Additions or deletions to survey maps or reports by other than the signing party or parties is prohibited without written consent of the signing party or parties. ❑ (1) All computed data or plotted features shown on survey maps supported by accurate survey measurements unless clearly stated otherwise. ❑ (m) Bearings, distances, coordinates, and elevations shown on a survey map shall be substantiated by survey measurements unless clearly stated otherwise. ❑ (n) Bearing reference (well established and monumented line) ❑ (o) A designated "north arrow" ❑ (p) Stated scale or graphic scale ❑ (q) Abbreviations in legend or notes. ❑ (r) Special conditions and any necessary deviation from the standards noted upon the map or report. ❑ (s) Responsibility for all mapped features stated on the map or report ❑ (t) Map or report clearly states the individual primarily responsible for the map or report when mapped features have been integrated with others. (u) Map Accuracy. (1) Vertical Feature Accuracy: ❑ (a) Vertical Control: Field -measured control for elevation information shown upon survey maps or reports shall be based on a level loop or closure to a second benchmark. ❑ (b) Closure in feet must be accurate to a standard of plus or minus .05 ft. times the square root of the distance in miles. ❑ (c) All surveys and maps or reports with elevation data shall indicate the datum and a description of the benchmark(s) upon which the survey is based. ❑ (d) Minor elevation data may be obtained on an assumed datum provided the base elevation of the datum is obviously different than the established datum. (2) Horizontal Feature Accuracy: ❑ (a) Horizontal Control: All surveys and maps or reports expressing or displaying features in a publicly published coordinate system shall indicate the coordinate datum and a description of the control points upon which the survey is based. ❑ (b) Minor coordinate data may be obtained and used on an assumed datum provided the numerical basis of the datum is obviously different than a publicly published datum. ❑ (c) The accuracy of control survey data shall be verified by redundant measurements or traverse closures. All control measurements shall achieve the following closures: Commercial/High Risk Linear: 1 foot in 10,000 feet; Suburban: Linear: 1 foot in 7,500 feet; Rural: Linear: 1 foot in 5,000 feet; ❑ (d) When statistical procedures are used to calculate survey accuracies, the maximum acceptable positional tolerance, based on the 95% confidence level, should meet the same equivalent relative distance standards as set forth in 61G17- 6.003(3)(p)(2.)(c) F.A.C. ❑ (e) Intended Display Scale: A11 maps or reports of surveys produced and delivered with digital coordinate files must contain a statement to the effect of: "This map is intended to be displayed at a scale of 1/_ or smaller". 61G17-6.004 Specific Survey, Map, and Report Requirements 01025-17 Technical Specifications FAPublic Works\ENGINEERING DIVISION PROJECTS\0455-8th Street Sidewalk Improvements 18th Ct to Old Dlxie\Admim\bid documents\Technical Specifications.doc
