Questions / Responses:
Question #1: Drawing / Specification 00200-1 – Completion Date ~ Will Owner consider
extending completion dates as some cooling tower manufacturer’s lead times are
extending 22 to 26 weeks?
o Answer – Question #1: The Owner will discuss Final Completion dates with the winning
bidder. Chesapeake Public Schools understands that equipment delays may occur and
that this is out of the contractor’s control.
Question #2: Drawing / Specification 15702 – Closed Circuit Coolers
(A) 2.4.2.E ~ Will 304 stainless steel gravity fed basin be acceptable?
o Answer – Question #2-A: No
(B) 2.4.2.F ~ Will a copper coil tested to 375 psig be acceptable? Copper coil is more
thermally efficient which will allow a 5 HP fan saving so we can switch from 15 HP to 10
HP (same for VFD). Copper coils are lighter and can be drained as needed. Estimated
salvage value per coil is $5,500.00 based on 15 year life span. Additionally, the coil is
not a pressure vessel and does not meet ASME / ANSIB31.5.
o Answer – Question #2-B: No
(C) 2.7.B ~ Is the control panel to be NEMA 3R painted steel or NEMA 3R stainless
steel?
o Answer – Question #2-C: 3R painted steel
(D) 2.5.C ~ Will motors inside air stream and internal mechanical platforms for access
be acceptable?
o Answer – Question #2-D: No
Question #3: General CCC Control Panel from Mechanical and Electrical Drawings ~ Is the
cooling tower manufacturer responsible for providing power to the heat trace and chemical
feed systems by others? If so, will you please provide amp draws from both systems so
the cooling tower panel step down transformers from 480V to 120V can be sized
appropriately?
o Answer – Question #3: The Contract does not define who is responsible for accomplishing
this work…only that it is a contract requirement.
Bidders are reminded to acknowledge all addendums by initialing next to the addendum number
on the Bid Form, Section 00310.
