QUESTIONS/CLARIFICATIONS

Question: If I need an additional site visit is it possible to make that happen?

Answer: The district has agreed to provide an additional site visit on 5/27 @

10AM.

Question: Is the district okay with moving the pump over a few feet to help with

getting the new chiller installed sooner or would the district like the new pad in

the same existing location?

Answer: The district requests the new pump to be installed in the same location

as the existing pump. The existing concrete pad will be reused and extended as

described in the addendum items above.

Question: Can we get an explanation on why the single point rather than dual

point? If the manufacturer cannot accommodate a single point connection is it an

acceptable modification to return to dual point connection?

Answer: The approved manufacturers listed in the specification each require

only a single-point electrical connection. Additionally, selecting an air-cooled

chiller with a single-point connection allows reuse of the existing overcurrent

protection with minimal disruption to the current installation. By contrast, a dual-

point connection air-cooled chiller would require a second overcurrent protective

device in the MCC or at the branch-circuit tap.
