Chan a Order 12 <br /> JUSTIFICATION FOR CHANGE <br /> 2.. Reason(s) for the change(s) (Continue on reverse if necessary) <br /> 2400 - Slope exterior Concrete at Electrical Building Doors <br /> This modification was made to assist in the drainage of storm water away from the building doors. <br /> 2410 -Telephone and EWEB vaults north of Taxiway Charlie <br /> These two existing vaults will be in the safety area of the new Taxiway Charlie. This work was not identified on the original <br /> plans. They are required to be aircraft rated as well as raised to match the new shoulder grades of Taxiway Charlie. The airport <br /> looked at the relocated the vaults but it was too costly. <br /> 2420 -Replace electrical vault at A4 and Rwy 16R/34L <br /> In order to collect the conduit from the primary runway and route it to the new electrical building, it is necessary to construct a <br /> new vault in the location of an existing vault on Taxiway A4. The existing vault requires replacement because it is not large <br /> enough to work in as well as to contain the additional conduit and wiring required to reconnect the primary runway to the new <br /> electrical building. This new vault will be located at the western terminus of the east-west main electrical duct and is required to <br /> accommodate additional wires from existing light and sign circuits. <br /> 2430 -Modify Upgrades to lighting control system <br /> This item provides 4 flat screen monitors that will fit better on the existing table spaces. Provide a larger printer so that 11 "X 17" <br /> sheets can be printed, and place the computer for the SRE building in a cleaner environment. <br /> 2440 -Lower fiber optics line around new apron <br /> The fiber line was constructed at an elevation above the final grade of the new asphalt on the east general aviation ramp <br /> (EGAR). The vault was constructed with a top elevation that is higher than the shoulder grades of the new EGAR. Both the <br /> conduit containing the fiber optics line and the vault at the southeast comer of the EGAR required adjustment. <br /> 2450 - Duct crossing for the FAA <br /> The FAA requested Wildish to construct this duct crossing. <br /> 2460 -Taxiway Papa duct crossing <br /> The documentation used for design showed a crossing in the location of this new crossing, but field investigation and excavation <br /> revealed that the crossing does not exist. Anew crossing was therefore required. <br /> 2470 Lighting at fiddlers green golf course <br /> This work is needed to reduce the amount of glare to the approaching aircraft from the golf course driving range. <br /> 2480 - Remove additional trees at Fiddler's Green golf course <br /> These additional fifteen trees were determined to penetrate the approach on Runway 16L and had to be removed. <br /> 2490 - Move fuel station 170-feet to the north <br /> It was determined after the SRE two building was designed and placed in its final location that there was a better location for the <br /> fuel tank to be positioned. The new location will provide better access for dispensing of diesel fuel for the airport's snow <br /> <br /> removal equipment. This fuel tank will provide fuel for both the new generator and the snow removal equipment. <br /> 5 <br /> <br />
