Jackson, MS 39208

1. STATEMENT OF WORK

The requirements in this document support the removal and installation of an Air Traffic Control Tower (ATCT) Cab Window Wetting System at the Air Traffic Control Tower (ATCT) at the Jackson-Medgar Wiley Evers International (JAN) airport. This design has its basis from a design a previous installation at the Nashville, TN ATCT. Please disregard all references on the drawing referencing BNA or Nashville International Airport. Additionally, specific references to electrical panel boards may differ at this location. Coordinate with local FAA representative to locate the breakers for this specific project. The work location access requires escort by FAA escort.

There are times of the year when the ATCT Cab windows develop heavy condensation due to temperature differences between the outside and the inside of the cab glass, rendering it difficult to see and control Air Traffic. The intent of this project is to remove parts of the existing wetting system, and install a new wetting system that will spray water on the exterior of the windows to clear the condensation. The project will include new permanent system piped directly into water supply line with new pumps, replaced copper piping with insulation on the outside of the facility roof, new sprinkler heads, new solenoid valves, a chemical feed tank, a pressure tank and a master control panel. The system shall be zoned to allow the operator to clear individual windows as well as multiple windows at the same time. The system shall drain after use to minimize the risk of standing water in the pipes, and reduce the risk of freezing.

Access to the facility shall be by escort only. The contractor shall be required to obtain Jackson Municipal Airport Badging to drive onto the secured airport to access the facility.

The successful Contractor shall coordinate that with the JMAA Badging office.

Sequence of Operation

Turn the system knob clockwise to a selected time interval (up to 5 minutes). This opens the main valve.

Select a window for defogging, and press and hold that switch to activate the spray nozzle. When the wetting is complete, another window may be selected. For proper operation, only one window at a time should be defogged.

A freeze protection control, (set for 35 degrees) is built into the system will automatically open all valves on the catwalk, and the main drain valve, and drain all water from the piping. The system may also be manually drained by placing the system timer in the ‘OFF’ position, and holding the DRAIN button for one minute.

Please do not operate the drain unless the timer is in the ‘OFF’ position.
