❑ (g ) Survey date (date of data acquisition . ) ❑ ( h ) Revision date for any graphic revisions (when survey date does not change. ) ❑ ( i) Map and report statement " Survey map and report or the copies thereof are not valid without the signature and the original raised seal of a Florida licensed surveyor and mapper. " ❑ Q) 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, 01025-18 Technical Specifications FAPublic Works\ENGINEERING DIVISION PROJECTS\0545-66Th Ave SR60 to 57th St (Arcadis)\Admim\Bid Documents\Technical Cnorifin�finnc iinr
