in full force except as specifically modified below.
Quotations appearing on the Proposal are to reflect the provisions of this Addendum. Failure to

1.
The City has elected to extend the deadline for the submission of bids for this

Responses to Questions:
1. Question: Confirm the number of hours required for the shutdown / change over process.
Response: Unknown. However, you should anticipate the shutdown / change over
process shall be conducted on a week-end coordinated with the City’s designated
Project Manager.
2. Question: Do you want an emergency generator or a stand-by generator?
Response: New generator will initially be a stand-by generator. However, in the future
it may be utilized as a life-safety generator. Therefore, it shall comply with all NFPA
requirements for a life-safety generator.
3. Question: Are you planning to keep and utilize the existing generator?
Response: The existing generator is to remain.
4. Question: Which generator (existing or new) will be supporting the City’s life safety
electricity requirements?
Response: Existing generator will currently be supporting the life-safety systems.
However, in the future the new generator may be utilized in this capacity.
5. Question: How are we to address the issue with the existing transformer? If CL&P requires
that the transformer be moved, who will be paying for the relocation?
Response: Removal of the existing utility transformer, if so directed by CL&P, will be
paid for by the City of Norwalk. However, the contractor shall be responsible for
coordinating all requirements and shutdown(s) of the existing utility transformer with
CL&P and shall pay all costs incurred as it relates to the scope of work as shown on
the drawings. The relocation of the transformer (if necessary) is not a part of the scope
of work for this project. If the relocation of the transformer is necessary, the City shall
assume the cost.
6. Question: What day of week do you want to perform the commission and or start-up and
testing of the new generator? Monday thru Friday? Weekend? Please confirm.
Response: Date of commissioning, start-up and testing for new generator is to be
coordinated with the City’s designated Project Manager and notification given to the
engineer. Most likely the startup and testing processes would be on a weekend, unless
otherwise directed by the City.
7. Question: Confirm the construction schedule. The lead time on a new generator could be up
to sixteen weeks. Would the City adjust the schedule to accommodate such equipment lead
time issues?
Response: Yes, the final completion date of the project shall be adjusted to
accommodate the lead time of the selected equipment. However, ideally the City is
optimistic such an adjusted schedule would allow for a completion by 08/01/2014.
8. Question: Do you have any concerns with placing the generator in front of the concert hall
windows? Of specific concern are the exhaust fumes from the generator entering the
building?
Response: The City has no concerns with the placement of the new generator in front of
the Concert Hall windows as these windows are presently inoperable. And Per NFPA
30, distance from building, including windows, is 5’-0”.
9. Question: Have the bid specification documents been approved by the City’s Building
Department?
Response: No.
10. Question: Have the bid specification documents had a code compliance review?
Response: No.
11. Question: Confirm the location of the proposed new manhole? Where is it going? Who is
responsible to coordinating with CL&P concerning this acceptability of the new manhole?
Response: Exact location of manhole is to be confirmed in field. Manhole should be
located as required to intercept existing secondary electrical conduits entering the
building from the existing utility transformer. The contractor shall be responsible for
coordinating all installation requirements and costs with the serving utility, CL&P.
12. Question: What is the age of this building?
Response: The City Hall building was formally Norwalk High School. The building was
constructed in 1936 and renovated in 1986 to become the current City Hall.
13. Response: What is the age of the underground feed(s) into the building?
Response: Construction drawings regarding the underground feeder into the building
obtained from the City of Norwalk are dated, February 13, 1986. We are unaware of
any replacements. The contractor shall provide a “Megger” test of the existing feeder
to access its condition. Firms that would like to view these construction drawing
documents are encouraged to contact the City’s Building Management Department.

Property Manager. Mr. Sgobbo can be reached via telephone at 203.854.7709 or via email at msgobbo@norwalkct.org

17. Question: I noticed under Article 5 that the project completion is 90 days after award.
After speaking with one of the generator manufacturers reps, I was told that the current lead
time could be between 20 and 24 weeks after approvals. Is this deadline set in stone or will it
be adjusted? Please confirm
Response: See response to question # 7 of this addendum.
18. Question: I have looked through the specs for the Norwalk City Hall Generator Bid and did
not see any documentation about a DAS Certification Can you please confirm whether or not
the DAS Certification is required for this project?
Response: No State of Connecticut funds shall be utilized for this project, hence DAS
prequalification requirements shall not apply to this solicitation.

all cost incurred by serving utilities for new and relocated utility services.” Typically anything
associated with the utility company will be billed directly to the owner. Please confirm that the
owner will be responsible for any utility company charges, if any.

utility company directly to the City and paid for by the City outside of the construction
contract. However, as part of the Contractor’s responsibilities under the Contract, the
Contractor shall coordinate, obtain required permits and manage all activities with the
utility company(ies).
20. Question: In reference to the liquidated damages in the spec ($200 per calendar day), will

acceptable.
23. Question: Can you please tell me what the expected Retainage % will be for this project?
Response: The project payment percent amount shall be five (5) per-cent.
