I STATEMENT OF PURPOSE THE PURPOSE OF THIS RECORD OF SURVEY IS TO DENSIFY THE 2010.00 EPOCH NGS CONTROL TO BE USED FOR DESIGN SURVEYS AND CONSTRUCTION ON VARIOUS SITES ALONG INTERSTATE 5 BETWEEN PM 38.41 AND 48.4, SPECIFICALLY I-5 ANCHOR PROJECT EA 10-1E300 AND PROJECT 1018000273. BASIS OF BEARINGS COORDINATES, BEARINGS, AND DISTANCES ARE BASED UPON THE CALIFORNIA COORDINATE SYSTEM OF 1983 (NAD83), ZONE 3, EPOCH 2010.00 ADJUSTMENT. BEARINGS, DISTANCES, AND COORDINATES ARE GRID. SEE TABLE ON SHEET 3. UNITS ARE US SURVEY FEET. BASIS OF ELEVATIONS THIS PROJECT IS BASED UPON THE NORTH AMERICAN VERTICAL DATUM OF 1988 (NAVD88). SEE TABLE ON SHEET 3. ELEVATION VALUES LISTED ARE IN US SURVEY FEET. GLASS NOTES GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) DATA WAS COLLECTED USING TRIMBLE R-10 AND R-8 DUAL FREQUENCY RECEIVERS BETWEEN APRIL 19, 2021 AND JUNE 30, 2021. THE SURVEYS WERE CONDUCTED EMPLOYING FAST STATIC SURVEY METHODS. THE FAST STATIC SESSIONS WERE A MINIMUM OF 10 MINUTES LONG. 2 METER FIXED HEIGHT TRIPODS WERE UTILIZED FOR ALL OBSERVATIONS. ALL CONTROL POINTS WERE OCCUPIED A MINIMUM OF 4 TIMES WITH ALL SET CONTROL POINTS TIED TO A MINIMUM OF 2 NGS CONTROL POINTS. SESSIONS EMPLOYED EITHER 2 OR 3 RECEIVERS. TRIMBLE TSC -3 SURVEY CONTROLLERS WITH TRIMBLE ACCESS VERSION 2017.21 WERE EMPLOYED. THE DATA INTERVAL SAMPLING RATE WAS 5 SECONDS MAXIMUM, WITH MANY SESSIONS SET TO 1 SECOND. SESSION VECTORS WERE ANALYZED IN TRIMBLE BUSINESS CENTER VERSION 5.40. SESSIONS WITH VECTORS EXCEEDING A POSITION DILUTION OF PRECISION (PDOP) ABOVE 5 WERE DISABLED. SESSIONS WITH LESS THAN 5 SATELLITES WERE DISABLED. FOR THE NETWORK ADJUSTMENT A 15 DEGREE MASK WAS UTILIZED. GEOID MODEL 18B WAS USED IN THE NETWORK ADJUSTMENT COMPUTATIONS. THE FREE ADJUSTMENT (UNCONSTRAINED ITERATION) PASSED THE CHI SQUARE TEST AT THE 95% CONFIDENCE LEVEL YIELDING A NETWORK REFERENCE FACTOR OF 1.01, IN THE FINAL FULLY CONSTRAINED ITERATION THE NETWORK ADJUSTMENT REPORT SHOWS THE ITERATION PASSING THE CHI SQUARE TEST AT THE 95% CONFIDENCE LEVEL WITH A NETWORK REFERENCE FACTOR OF 0.99. SEE THE TABLE ON SHEET 3 TO SHOW WHICH NGS CONTROL POINTS WERE HELD FOR THE HORIZONTAL COMPONENT, THE VERTICAL COMPONENT, OR BOTH. THE GNSS SETUP ERRORS FOR BOTH THE HEIGHT OF ANTENNA AND THE CENTERING ERROR WERE SET TO 0.01'.
