C. Field measurements of vertical or horizontal dimensions of constructed <br /> improvements shall be obtained so that the constructed facility can be delineated in <br /> such a way that the location of the construction may be compared with the <br /> construction plans. Clearly shown by symbols, notations, or delineations, those <br /> constructed improvements located by the survey. <br /> D. All vertical information (elevations) provided on the Record Drawings shall be <br /> referenced to the North American Vertical Datum of 1988 (NAVD 88) unless <br /> otherwise specified by the Project Engineer. <br /> E. The horizontal information provided on the Record Drawings shall be referenced to <br /> the State of Florida, State Plane Coordinate System, Florida East Zone as <br /> established by Global Positioning System (GPS) which meets or exceeds Third <br /> Order Class I Accuracy Standards according to current publication of the Federal <br /> Geodetic Control Committee (FGCC) procedures. <br /> F. All Record/As-Built drawings shall be prepared in digital format (ACAD Civil 3D <br /> 2013) and shall utilize the digital design drawings as prepared by the Project <br /> Engineer as abase for the Record/As-Built drawings. It is the responsibility of the <br /> Surveyor to request these files from the Contractor or Project Owner in order to <br /> produce the Record/As-Built drawing set. <br /> G. ALL improvements proposed to be constructed as shown on the approved <br /> construction plans shall be field measured upon completion and shown on the <br /> Record/As-Built survey. Any improvements that appear in both plan and profile <br /> views shall show the Record/As-Built information in both views. <br /> H. The following items are required to be shown on all Indian River County project <br /> Record/As-Built drawings submitted to the County: <br /> DRAINAGE: <br /> 1. Right-of-way Swale/Drainage — All culvert inverts, elevations and station <br /> offsets; inlet grate and bottom elevations; swale beginning and end bottom <br /> elevations; and highs and lows along top of bank. Size of swale. <br /> 2. Pipe Culvert/PVC Sleeves —All inverts, pipe size, stations and offsets. <br /> 3. Outfalls — All pipe inverts, pipe size, elevations and station offsets, weir box <br /> elevations, weir elevation, bleeder elevation and sizes. <br /> 4. Roadway/Off Site Drainage — All inverts, elevations and station offsets; <br /> manhole top elevation; grate top elevations. <br /> 5. Retention Ponds — Provide perimeter elevations, grade breaks, depths and <br /> calculated pond areas at control elevation and grade breaks above and below <br /> water surface. Show as-built of typical cross section as shown on design plan. <br /> ROADWAY: <br /> 1. Stations and offsets related to controlling baseline and elevations of all <br /> structures, side street and major driveway radius returns (edge of pavement), <br /> 01025-3 Technical Specifications <br /> F:\Public Works\ENGINEERING DIVISION PROJECTS\1049_8th St Sidewalk Improvements(58th Ave to 21st Court)WdmimWd <br /> documents\LAP Documents\Master Contract Documents\Technical Specifications.doc <br />
