Written by GovTribe AI ·

This is an Existing Conditions Survey document prepared by Naval Facilities Engineering Systems Command (NAVFAC) Mid-Atlantic for the New Fire Apparatus Bay project at Cheatham Annex Naval Weapons Station Yorktown, Norfolk, Virginia (Project No. P1476U).

The survey provides a comprehensive topographic and utility mapping of the project site based on field data collected in November-January 2025. Key existing conditions include identification of underground utilities (sanitary, storm, water, electrical, communications, and geothermal systems) with pipe sizes and materials documented in accompanying schedules. Notable utilities include abandoned 6-inch cast iron and 8-inch concrete lines, active 12-inch clay, PVC, and HDPE lines, and 15-inch HDPE systems. Elevations reference North American Vertical Datum (NAVD) 1988, Geoid 18, based on rapid static GPS observations from November 4, 2024, while coordinates utilize Virginia State Plane Coordinates (NAD 1983) in international feet. The survey identifies a buildable area and laydown area within the project limits along Sanda Avenue and Cold Storage Road. The document explicitly notes that utility locations are based on geophysical methods (Level B per ASCE 38-02 standards) performed by UtiliQuest and InfraMaps in November 2024, with the caveat that contractors must field-verify all utility status and locations and conduct their own complete survey. The survey is marked preliminary and not for construction.

1. TOPOGRAPHIC SURVEY BASED ON FIELD DATA OBTAINED BY NAVFAC MID

ATLANTIC, COMPLETED IN JANUARY 2025. THIS SURVEY IS PROVIDED FOR

CONTRACTOR REFERENCE ONLY. CONTRACTOR TO PROVIDE A NEW

COMPLETE SURVEY.

2. THE EXISTENCE, SIZE AND/OR LOCATION OF UTILITIES ARE NOT

GUARANTEED BY THIS SURVEY. UTILITIES SHOWN ARE BASED ON

ABOVEGROUND STRUCTURES, AVAILABLE AS-BUILT PLANS, GIS DATA

PROVIDED BY THE INSTALLATION, AND UTILITIES MARKED BY UTILIQUEST

AND INFRAMAPS. UTILITIES DESIGNATED AS "ABAND." ARE ASSUMED TO BE

ABANDONED BASED ON THE DEMOLITION OF SUPPORTING

FACILITIES/BUILDINGS, AND HISTORICAL DRAWINGS. FIELD VERITY THE

STATUS AND LOCATION OF ALL UTILITIES.

3. UNLESS NOTED OTHERWISE THE LOCATION OF ALL WASTEWATER FORCE

MAINS, WATER, ELECTRICAL, COMMUNICATIONS, AND GEOTHERMAL ARE

BASED ON UTILITY DESIGNATION BY GEOPHYSICAL METHODS (LEVEL B PER

ASCE 38-02 STANDARDS) AS PERFORMED BY UTILIQUEST AND INFRAMAPS,

NOVEMBER 2024. UTILITY LOCATIONS THAT ARE BASED ON OTHER SOURCES

(IE GIS, OR AS-BUILTS) ARE NOTED.

4. ELEVATIONS ARE IN FEET AND REFER TO NORTH AMERICAN VERTICAL

DATUM (NAVD) 1988 GEOID 18, ARE BASED ON RAPID STATIC GPS

OBSERVATIONS RECORDED ON NOVEMBER 4, 2024.

5. COORDINATES SHOWN REFER TO VIRGINIA STATE PLANE COORDINATES

(NAD 1983). COORDINATES ARE BASED ON RAPID STATIC GPS

OBSERVATIONS RECORDED ON NOVEMBER 4, 2024. UNITS ARE

INTERNATIONAL FEET.

6. THIS TOPOGRAPHIC SURVEY WAS COMPLETED UNDER THE DIRECT AND

RESPONSIBLE CHARGE OF WILLIAM JON WHITE, FROM AN ACTUAL GROUND

SURVEY MADE UNDER HIS SUPERVISION. THE IMAGERY AND/ OR ORIGINAL

DATA WAS OBTAINED IN NOVEMBER AND DECEMBER 2024 AND JANUARY

2025. THIS MAP MEETS MINIMUM ACCURACY STANDARDS UNLESS

OTHERWISE NOTED.
