At the time of the opening of bids each bidder will be presumed to have inspected the site
and to have read and to be thoroughly familiar with the Contract Documents (including all
addenda). The failure or omission of any bidder to examine any form, instrument, or
document shall in no way relieve any bidder from any obligation in respect of its bid.
6. Information not Guaranteed
All information given in the Contract Documents relating to subsurface and other
conditions, natural phenomena, existing pipes, and other structures is from the best sources
at present available to the OWNER. All such information is furnished only for the
information and convenience of bidders and is not guaranteed.
It is agreed and understood that the OWNER does not warrant or guarantee that the
subsurface or other conditions, natural phenomena, existing pipes, or other structures
encountered during construction will be the same as those indicated in the Contract
Documents.
It is further agreed and understood that no bidder or CONTRACTOR shall use or be
entitled to use any of the information made available to it or obtained in any examination
made by it in any manner as a basis of or grounds for any claim or demand against the
OWNER or the ENGINEER, arising from or by reason of any variance which may exist
between the information made available and the actual subsurface or other conditions,
natural phenomena, existing pipes or other structures actually encountered during the
construction work, except as may otherwise be expressly provided for in the Contract
Documents.
7. Bid Security
Each bid must be accompanied by a certified check, a bid bond, cash, a treasurer's or

holidays excluded, after the opening of bids, and the remaining deposits will be returned
promptly after the OWNER and the accepted bidder have executed the Contract, or if no

of the bidder at any time thereafter.

9. Addenda and Interpretations
No interpretation of the meaning of the plans, specifications or other pre-bid documents
will be made to any bidder orally, and if provided orally, shall not be relied upon by bidders
unless confirmed in a written addendum. All information given to bidders other than by
means of the plans, specifications, or by addenda, as described below, is given informally
and shall not be used as the basis of a claim against the OWNER or the ENGINEER.
Every request for such interpretation should be in writing (typed, not handwritten)
addressed to the ENGINEER: Weston & Sampson Engineers, Inc., 712 Brook Street, Suite
103, Rocky Hill, Connecticut, 06067 Attention: Mr. Kevin McKenna. or sent via email

working days prior to the date fixed for the opening of bids.
Any and all such interpretations and any supplemental instructions will be in the form of
written addenda to the specifications which, when issued, may be viewed and downloaded
as a Portable Document File (PDF) at the website provided in the Advertisement for Bid. A
notification of addenda will be emailed to all prospective bidders to email addresses
furnished by them for such purposes. Bidders will be required to sign for all documents,
acknowledging receipt of bid documents and addenda. Failure of any bidder to receive any
such addendum or interpretation shall not relieve such bidder from any obligation under its
bid as submitted, and each bidder must confirm for itself that it has received all addenda.
All addenda so issued shall become part of the Contract Documents.
10. Comparison of Bids
Bids will be compared on the basis of the quantities and unit and lump sum prices stated in
the bid forms.
In the event that there is a discrepancy in Section 00410, FORM OF GENERAL BID
between the lump sum or unit prices written in words and figures, the prices written in
words will govern.
The OWNER agrees to examine and consider each FORM OF GENERAL BID submitted
in accordance with the terms and conditions set forth herein and as set forth in Section
00410, FORM OF GENERAL BID.
11. Statutes Regulating Competitive Bidding
Any bid, which does not comply with the provisions of the State of Connecticut General
Statutes, need not be accepted and the OWNER may reject every such bid.
12. Right to Reject Bid
The OWNER may consider informal any bid not prepared and submitted in accordance
with the provisions hereof and may waive any informalities or reject any and all bids,
should the OWNER deem it to be in the public interest to do so.
00200-5

The OWNER may also reject bids which in its sole judgment are either incomplete,
conditional, obscure or not responsive or which contain additions not called for, erasures
not properly initialed, alterations, or similar irregularities, and may reject bids for any other
reason permitted by law, or the OWNER may waive such omissions, conditions or
irregularities.
13. Ability and Experience of Bidder
All general contractors shall file with their bids a copy of their DAS certificate of eligibility
showing that they are eligible to bid on projects of this category, value, and up to an
aggregate limit.
No award will be made to any bidder who cannot satisfy the OWNER that it has sufficient
ability and experience in this class of work and sufficient capital and plant to enable it to
prosecute and complete the work successfully within the time named. The OWNER's
decision or judgment on these matters will be final, conclusive, and binding to the fullest
extent permitted by law.
The OWNER may make such investigations as it deems necessary, and the bidder shall
furnish to the OWNER, under oath if so required, all such information and data for this
purpose as the OWNER may request.
14. Conditions of Work
Each bidder must inform itself fully of the conditions relating to the construction of the
project and the employment of labor thereon. Failure to do so will not relieve a successful
bidder of its obligation to furnish all material and labor necessary to carry out the provisions
of its contract. Insofar as possible the CONTRACTOR, in carrying out its work, must
employ such methods or means as will not cause any interruption of or interference with
the work of any other contractor.
15. Security for Faithful Performance
Simultaneously with its delivery of the executed Contract, the CONTRACTOR shall
furnish a surety bond or bonds as security for faithful performance of this Contract and for
the payment of all persons performing labor and materials under this Contract as specified
in Section 00700, GENERAL CONDITIONS included herein each in the amount of 100
percent of its bid. The surety on such bond or bonds shall be a surety company qualified
to do business under the laws of the Commonwealth and satisfactory to the OWNER. The
bonds shall remain in force for one year after final acceptance of the work by the OWNER,
unless the OWNER, in writing, releases the CONTRACTOR from the obligation sooner.
16. Power of Attorney
Attorneys-in-fact who sign Contract bonds must file with each bond a certified and
effectively dated copy of their power of attorney.
