❑ ( 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. " ❑ 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 61G17m 6 . 003 ( 3 ) ( p ) ( 2 . ) ( c ) F .A . C . ❑ ( e ) Intended Display Scale : All 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" . 01025- 18 Technical Specifications F : \Public Works\ENGINEERING DIVISION PROJECTS\1142 - Misc Culvert Replacements\Admim\bid documents\Technical Specifications . doc
