A10. Yes.

Q11. Is the end of day Thursday July 9th the cut-off time for questions?

A11. As of this response, no more questions are being accepted.

Q12. There is new domestic cold and hot water piping that is not specified to be insulated.

Does that piping require insulation? If yes, please clarify type and thickness of insulation required.

A12. Yes, pipe insulation is required on all new piping. Cold piping shall have 1” of elastomeric foam and hot piping shall have 2” of mineral fiber insulation as described in specification section 230700.

Q13. Duct from the space back to AHU-1 is labeled Exhaust and Return. Does any or all of this duct require external insulation?

A13. This air is “returned” to the air handling unit but it is ultimately exhaust out of the building so it does NOT need to be insulated.

Q14. It notes on the drawings that all exposed duct is to be painted. Will exposed round supply air duct in a room serving same (like that in rooms 110 and 121) be left bare and painted, or will you require fiberglass pipe and tank insulation that will then be painted?

A14. All supply ducts shall be insulated including exposed ones. These ducts in questions should be insulated in the appropriate fiberglass insulation and then painted.

Q15. Will exposed rectangular supply in room 100 be left bare and painted, or insulated with fiberglass board and then painted?

A15. All supply ducts including these ventilation supply ducts shall be insulated. These ducts in questions should be insulated in the appropriate fiberglass insulation and then painted.

Q16. Please reference specification section 230700-16,3.9.B.6 – Says Ventilation Intake in mechanical rooms does not insulate. What is this duct, as it seems like this would be the Outdoor air intake which insulates with fiberglass board? Please clarify.

A16. The ventilation intake this is referring to is that associated with the exhaust fan that is specifically for that given room that is thermostatically controlled. The intake into the AHU should be insulated like supply air.

Q17. Please reference specification section 230700-16,3.9.B.6 – Says Exhaust ducts in mechanical equipment rooms does not insulate. However, it states exhaust between damper and building exterior does insulate in 3.9,A.5? Does Exhaust from AHU-1 to exterior require external insulation? Please clarify.

A17. If the exhaust air damper is in the unit, it will need to be insulated from the unit to the louver. Any duct exposed to winter temperatures will have to be insulated. However, if the damper is at the louver, then only the louver plenum would need the insulation and the insulation could stop at the damper.
