Corrections and clarifications to Q&A 4-13

Q5: I do not see any guidance in the drawings for insulation. I know this is an unheated structure so I will assume no insulation in the roof or walls. Our recommendation in a building like this is always to put 3” or 4” of insulation in the roof for 2 main purposes: 1. Noise reduction and 2. Condensation blanket. Without this insulation they are likely to get condensation on the inside of the roof panels and water dripping. Please advise if insulation should be included for this purpose.

A5: I agree, there is nothing indicated. I’ve deferred to Engineer on this since I was not involved in design. Condensation may be a concern; noise is not. Should include 4” of roof insulation to provide a vapor barrier (faced insulation). An amendment will be created to address this.

Q10: Since building is un-insulated; Varco Pruden won't issue any type of warranty on the roof and wall panels due to the high probability of condensation on interior of panels. Would need to provide, at a minimum, 3" thick, faced fiberglass insulation (roof and walls) for condensation control AND "roof rumble" control. Please confirm if the 3” roof and wall insulation should be included. Refer to no. 2 above.

A10: Refer to no. 5 above.

Q13: Plan Sheet E001 makes note of running a new feeder from the existing transformer. I am assuming this transformer is owned by the Energy Company and typically they run the conduit and conductors from the transformer to the CT Cabinet. Can you verify if this is to be run by the contractor or if this will be “By Others.”

A13: MG&E is our utility. Contractor must coordinate directly with them. They may have to hire MG&E as a subcontractor or arrange to do the work under their direction.
