6.4. Determine the distance from the building entrance panel to the matrix connection point, and identify any obstructions or obstacles that interfere with running the antenna coaxial cable to the matrix.

6.5. Determine the primary base power available at the site. Identify the circuit breaker panel locations.

6.6. Obtain available drawings of proposed cable routes and of existing equipment and splice/transition points.

6.7. Determine if there is an existing circuit breaker panel in the facility to accommodate the new load for the RLP including the power requirement for an electric winch just in case an electrically-powered method to raise/lower the antenna is selected over a manually-powered method. Identify any modifications or additions to the existing power system required to accommodate the HFGCS load.

6.8. Determine if there is space in the existing SCOPE equipment rack to accommodate the RLP controller interface unit.

6.9. Identify proposed routing of utility runs to new end points and any obstructions to be avoided/protected along the route

6.10. Determine if there are any control cards/comports and cabling that are required to support the azimuth control of the new RLP antennas

6.11. Determine if there are existing cable troughs in the facility that will accommodate the new antennas coaxial cables.

7. Inside Receive Facility

7.1. Determine if a matrix port vacancy exist for the new antennas.

7.2. Determine the type of hangers/cable trays used inside the buildings to support cable runs.

7.3. Determine where the coaxial cable ground kit will tie into the building EEN as the coax enters the building.

7.4. Determine the distance from the building entrance panel to the matrix connection point, and identify any obstructions or obstacles that interfere with running the antenna coaxial cable to the matrix.

7.5. Determine the primary base power available at the site. Identify the circuit breaker panel locations.

7.11. Determine if there are existing cable troughs in the facility that will accommodate the new antennas coaxial cables.

7.12. Are there existing cables in the cable trough that are no longer in use and can be removed? This can be coordinated with site to have them removed prior to install.

8. Survey Completion Conference

8.1. Identify task/items the site can provide/support before and during the installation of the new antenna.

8.1.1. (Some of this the site PM/POC should be able to inform the SPO prior to TDY while other items may be discovered by the contractor)

8.2. EXAMPLES:

8.2.1. -Site to pull dig permit

8.2.2. -Provide access to TX facility and gaining EAL access

8.2.3. -Making sure proposed locations and where the removal of antennas has been mowed

8.2.4. -Storage access

8.2.5. -Coordinate with the farmer to have sheep removed from proposed installation areas

8.2.6. -Coordinate delivery of equipment prior to LWI arrival on site.

8.2.7. -Proved escort when working within the facility

8.2.8. -Inside IC fences need to be mowed by site prior to removal effort being started

8.3. Flag any incomplete items, written Action Items and the POC assigned to complete the action.

8.4. Track all open action items and coordinate with the SPO.
