Adden­dum #1 (Pre-Bid Questions)


Both cables are spec­i­fied at 60ft. We do not rec­om­mend a 60ft 28v cable because the volt­age drop is too great. We rec­om­mend 50ft as the longest 28v cable, please accept indus­try stan­dard for the 28v cable.

Answer: 50ft cable length is accept­able for 28 VDC pro­vid­ed that GPU sys­tem per­for­mance is

not impact­ed.


Does the air­port want spe­cial coat­ings in the coils con­sid­er­ing the cor­ro­sive nature of the area? Also does the air­port want a spe­cial paint or gal­va­niza­tion for the frame for the same con­di­tions. Both of these upgrades will length­en the life of the PCA unit.

Answer: As per spec­i­fi­ca­tion is it assumed equip­ment to be pro­vid­ed will be com­pat­i­ble with

pas­sen­ger board­ing bridge and designed/​manufactured to with­stand local environment

con­di­tions. No spe­cial pro­vi­sions are required beyond those specified.
