Q: 55 - The Type A 1 high x 2 wide in the response contradicts the response provided in Amendment #4 response to question 12 listed above. Please confirm that Type A is 1 coil, (ie 1 high x 1 wide).

There is no schedule for a Hot Water coil in ACU-1A on drawing 245-497.

A: 55- The Type A coil is, 1 high x 1 wide per response to #12 in Amendment # 4.

See attachment A for Hot Water Coil schedule for ACU-1A.

Q: 56- Response #to question 51 ACU-1A: states Cooling coil should be Type C, 1 high x 2 wide, steam coil should be Type A, 1 high x 2 wide and hot water coil should be 2 high x 1 wide.

A: 56- Response to Amendment #6 question #51 should read:

“Cooling coil should be Type C, 1 high x 2 wide, steam coil should be Type C, 1 high x 2 wide and hot water coil should be Type A, 1 high x 1 wide.”

Q: 57- On drawings 104 of 164, 106 of 164 and 107 of 164, the ACU elevation detail views on the above drawings, state that we are to follow notes 4 and 9. Note 9 does not appear on these pages, what is note 9? Also these same pages state in note 1 we are to remove the entire ACU and discard the unit. There is not a note 4 given in any of the details on this page telling us to reinstall a new unit. Are reinstalling a new ACU?

A: 57- Plan view and elevation view should reference notes 1 through 8. Delete reference to note 9. Note 1 does not remove the entire unit. Removes fan and cooling coil section.

Note 4 states: “ Provide new modular type horizontal draw-thru ACU unit with fan and cooling coil with all…..”. There is no note about “reinstalling”.
