The contractor’s tests shall check for cable faults (grounds, shorts, crosses, opens), splicer’s errors (splits, reverses, transpositions), shield continuity and insulation resistance (insulation resistance on existing cables is accomplished on spare pairs only). The contractor shall not be responsible for correcting existing cable faults, splicer’s errors, open shield continuity or low insulation resistance; however, the 633 CS QAE must be notified of such conditions immediately upon identification so the government can correct the deficiencies.

3.6.2. New Cables. After splicing and terminating new cable and prior to splicing any new cable into existing cable, the new cable will be tested and documented to be free of cable faults (grounds, shorts, crosses, and opens) and splicer’s errors (splits, reverses, and transpositions).

3.6.3. After splicing and terminating new cable and prior to splicing new cable into existing cable, insulation resistance as tested on a minimum of three conductors in each 25 pair group of the new cable against all other conductors of the cable and the shield, shall be documented to be of a value that is satisfactory for the length and type cable being tested.

3.6.4. After splicing and terminating new cable and prior to splicing new cable into existing cable, test to ensure the cable shield is continuous from the MDF to each distant termination point.

3.6.5. After splicing new cable into existing cable test the cable for end-to-end cable faults (grounds, shorts, crosses, and opens) and splicer’s errors (splits, reverses, and transpositions). Any cable faults or splicer’s errors not documented on existing cable test shall be cleared by the contractor, if caused by the new cable installation.

3.6.6. Insulation resistance as tested on a minimum of three non-working conductors in each 25 pair group of the cable shall be documented to be of a value that is satisfactory for the length and type cable being tested.

3.6.7. Loop Resistance Tests: After all splicing and terminating is complete, make a D.C. loop resistance measurement on all affected (non-working) cable pairs. Measure from all terminals back to the cable origin or central office

3.6.9. Test results may be recorded on locally developed test sheet.

3.6.10. Where the contractor uses an existing ground point, it shall be tested prior to being connected to the system. Even though the National Electrical Code calls for a resistance to ground not to exceed 25 ohms, Military Handbook 419A, paragraph 2.2.2.2 states that 25 ohms is not low enough. In order to protect personnel and equipment, MIL-HDBK 419A recommends a design goal of 10 ohms for communications systems where practical. If the ground point proves unsuitable, the contractor shall notify the 633 CS QAE in writing of the defective ground. The tests to be performed on the grounds shall measure the ground potential (ability to dissipate voltage through the ground point to the earth).

GEOSPATIAL INFORMATION

1.0 General Global Positioning System Service Requirements

1.1. The Contractor shall use GPS equipment supplemented with land surveying equipment and electronic underground cable locating equipment needed to locate direct buried cable, necessary to collect required Communication Feature Location Data (CFLD) following the “Geospatial Positioning Accuracy Standards, Part 4: Architecture, Engineering, Construction, and Facilities Management,” (FGDC)-STD-007.4-2002 published by the Federal Geographic Data Committee.

This standards document can be found at http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part4/FGDC-endorsed-standard . Coordinates of communication features shall be located to within one foot spatial accuracy in the horizontal plane at the 95% confidence level. The methodology used for testing and reporting accuracy shall be in accordance with the Geospatial Positioning Accuracy Standards, Part 3: “National Standard for Spatial Data Accuracy”, (FGDC)-STD-007.4-2002) This standards document can be found at: http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part3/chapter3

1.2. Geospatial data shall overlay on the installation’s most current orthorectified imagery provided by 633CES/CEG Langley AFB, Virginia. The collected data will incorporate the coordinate and projection system of the imagery, NAD 83 Virginia State Plane South, FIPS 4502.

1.3. Required Attribute Data and Metadata for CFLD Population

1.3.1. The contractor shall use GPS to determine horizontal position of communication features and shall record all required CFLD.

1.3.2. Entity naming convention, attribute fields, and domain values used for data entry in Appendix A are derived from the 38th EIG Communications Mission Data Set Schema.

1.3.3. The contractor shall complete all metadata elements marked mandatory and mandatory-if-applicable as defined by the FGDC Content Standards for Digital Geospatial Metadata for each set of CFLD collected. This standards document can be found at: http://www.fgdc.gov/standards/projects/FGDC-standards-projects/metadata/base-metadata/v2_0698.pdf

1.3.4. Metadata must include an NSSDA accuracy statement at the 95% confidence level. “Geospatial Positioning Accuracy Standards, Part 3: National Standard for Spatial Data Accuracy,” published by the Federal Geographic Data Committee (FGDC), dated July 1998. This standards documentation can be found at: http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part3/chapter3

1.4. Quality Control: The contractor shall utilize a topology build and clean routine and assure the CFLD has the following:

· No erroneous overshoots, undershoots, dangles or intersections in the line work.

Features shall be snapped where applicable, for example, Comm_Dbsplice snapped to Comm_Path_Segment.

· Lines should all be continuous. Pseudo-nodes should only exist where the attributes of a line change.

· No sliver polygons.

· All polygons completely close and have a single unique centroid.

· Digital representation of the common boundaries for all graphic features must be coincident, regardless of feature layer.

1.5. Spatial coordinates for the location of maintenance holes and cable vaults shall be recorded for the center of the maintenance hole lid. Spatial coordinates for the location of handholes, pedestals, and buried splices shall be recorded for the top center of the feature. Spatial coordinate data for the location of cable installation pathways shall be recorded at a minimum every 50 feet and each offset, turn, or bend in a cable installation pathway must also be recorded so that the coordinates for any point along the turn pathway will fall within the allowable accuracy.

1.6. The Contractor shall be responsible for providing all required GPS, land surveying equipment, data loggers and other equipment including computer software, hardware, and any other tools, labor, and materials necessary to provide the CFLD electronically on CD-ROM storage media.

2.0 Requirements for CFLD Deliverables

2.1. The CFLD attribute and location information shall be stored and submitted in an Environmental Systems Research Institute (ESRI) Shape File format. The shape files must be compatible with the current software used by the 633CES/CEG Langley AFB, Virginia. Its format shall be within a folder named the same as the prefix of the shape file.
