RFP Reference (Sect/Para/Page) QUESTION GOVERNMENT RESPONSE

9/11/2018 1 The statement of work is calling for three phase power for the motors. Can you please confirm this as existing power is currently single phase.

Current power to the inoperable existing security grilles is 120V single phase

The Advance performance Doors are not like the grilles in place now, they require a larger head plate (where the curtains roll up) the ADP grille will require 26” with the hood flange turned under so the new ADP grille will hang down into the opening at least 8” into the opening (clear opening height of approximately of 11’-4”)

It is acceptable to have the door opening be reduced from what it is now. Any mounting structure that will need to be put in is the contractors responsibility

9/11/2018 3

Side room requirements go up sizably with ADP grille, on the motor side it is 16-1/2” and the non-drive side is 11”. The control panel inside is approximately 14” x 14”. You call out controls on inside, existing grilles have controls outside also do you want them outside on new grilles?

Contols for the grilles can be mounted on the outside with the door, but the push buttons to accuate the doors must be mounted inside at current locations.

9/11/2018 4 You call out 3-phase power? New contractor needs to know up front for bidding.

The current power is 120v single phase new power will have to be run for the desired security grilles with drives as a single phase model appears to be not present.
