APPENDIX B<br />

SOP B1.9<br />

Land Surveys<br />

A state-licensed professional surveyor will perform surveys. Signed and sealed originals of all field<br />

notes, survey plats and drawings shall be submitted to the Contractor. Surveys should at a minimum<br />

conform to the requirements stated in Article 12.8.2 of the New Mexico Administrative Code (NMAC),<br />

Minimum Standards for Surveying In New Mexico. The methods and tolerances provided in USACE<br />

Engineering Manual (EM 1100-1-1005) should also be consulted when performing surveys.<br />

Monitoring Wells—Coordinates and elevations will be established for each monitoring well. The<br />

coordinates will be to the closest 0.1ft and referenced to the State Plane Coordinate System. If the State<br />

Plane Coordinate System is not available an existing local grid system will be used. A ground elevation<br />

to the nearest 0.01 ft and an elevation for the top of the well riser to the closest 0.01 ft will be obtained<br />

for each well. All positions and coordinates of all permanent points within the control traverse will be<br />

shown.<br />

Soil Borings/Sampling Points—All soil sampling locations will be located horizontally and vertically as<br />

required following procedures outlined in the previous paragraph.<br />

Physical Features—At each site, all above-ground and, where possible, underground physical features<br />

will be either verified with previous mapping or determined as required. All above ground physical<br />

features will be located/verified to the nearest ft. Permanent control monuments will be placed in<br />

accessible locations within the limits of the work if no existing permanent monuments are located within<br />

1,000 ft of a site. One set of monuments is allowable for adjacent sites. These monuments will be set no<br />

closer than 500 ft to each other. The permissible error for the traverse closure of permanent control<br />

monuments is 1/5,000 ft.<br />

Documentation and Deliverables—The location, identification, coordinates, and elevations of the wells<br />

and monuments will be plotted on maps with a scale large enough to show their location with reference<br />

to other structures at the individual sites. A tabulated list of the monitoring wells and monuments, copies<br />

of all field books, and all computation sheets will be prepared and submitted to the Contractor. The<br />

tabulation will consist of the designated identification number of the well or monument, and its northing<br />

(X-coordinate), easting (Y-coordinate), and elevation.<br />
