Fire Station No. 26 Generator Replacement Addendum #1
TO: Prospective Respondents and Other Interested Parties
FROM: The Village of Buffalo Grove Finance Department
ISSUE DATE: July 21,2020
SUBJECT: ADDENDUM#1
Note: This Addendum is hereby declared a part of the original Bid
documents and in case of conflict, the provisions in the following
Addendum shall govern.
The following clarifications shall be made to the bid documents for the Fire Station No. 26
Generator Replacement project.
Q. Who is responsible for the generator pad?
Response: The Village will excavate for and construct the concrete generator pad.
Q. Who is responsible for trenching of the power and communication to the generator
location?
Response: The Village will provide trenching from the existing building to the generator
location.
Q. Who is responsible for removal of existing generator?
Response: The Bidder shall be responsible for disconnect of the existing generator. The
Village will be responsible for physically removing and disposal of the generator.
Q. Drawing E1.00 is showing a new 400 amp 4P ATS. Using a 4P switch requires
grounding that is not shown. Using a 3P switch does not require the grounding that a 4P
requires. Can you provide the grounding detail or change it to a 3P?
Response: At the generator,provide a grounding triangle of(3)ground rods,spaced 10 feet
apart,bonded together and grounded to the generator with#1/0 ground. The generator
shall be grounded as a separately derived service.

V oBG-2020-19
Q. It is unclear on the drawings who is supplying the Generator.There are two different
information on drawings. Can you please confirm?
Response: The generator is to be provided by the Electrical Contractor as noted on the
Electrical drawing. The drawing referenced as part of the RFI is the Mechanical drawing,
which is why it indicates the generator is "by other". To be clear, the purchase and
installation of the generator will be the responsibility of the Bidder,with the exception of
work by the Owner noted on the drawings.
Q. How would you like to have bid bond submitted—appropriate bid bond information —
awarding entity—bid bond requirements,etc?
Response: Bid Security can be mailed to the Village or dropped off at the walk up window
at 50 Raupp Blvd. in advance of the bid opening.
Q. Is a certified/cashiers check to the Village of BG an acceptable alternate in lieu of the bid
bond?
