INSTRUCTIONS TO BIDDERS
The bidder must file its bid with the Project Coordinator, Department of Public Works of the City of Rohnert
Park, California, using the copy of the Bidder's Proposal and Schedule of Bid Prices furnished with the
specifications. These documents must be placed in a sealed envelope marked,
WELL NOS. 33, 35 AND 40 REHABILITATION PROJECT
and addressed to the Project Coordinator, Attn: Kelsey Nguyen. Said sealed bids must be dropped off in
the mailbox to the left of the main door in front of the Department of Public Works Corporation Yard
building, located at 600 Enterprise Drive, Rohnert Park, CA 94928 before 2:00:00 PM on Wednesday,
May 27, 2026. The bidder must not file the book of Special Provisions or the Contract Drawings with his
bid.
The bidders' attention is directed to the schedule of bid prices that requires this project be bid as a combination
of unit price and lump sum contract.
Bid Forms. Each proposal and all bid submittals must conform and be responsive to the Invitation and the
Plans, Specifications and Contract documents.
The wording of the proposal and bid submittals must not be changed. Any additions, conditions, limitations,
or provisions inserted by the bidder will render the proposal irregular and may cause its rejection. Erasures
or interlineations in the proposal or other submittals must be explained or noted over the signature of the
bidder.
In case of discrepancy between a unit price and the total price set forth for the unit price item, the unit price
shall prevail. Discrepancies between the indicated sum of any column of numerals and the correct sum
thereof will be resolved in favor of the correct sum. Discrepancies between written words and figures, or
words and numerals, will be resolved in favor of the words.
Prices. All proposals must give the prices proposed, both in writing and in figures in the respective spaces
provided, and must be signed by the bidder, who must fill out all blanks in the proposal form as therein
required.
Rejection of Bids. Proposals may be rejected if they show any alterations of form, additions not called for,
conditional proposals, incomplete proposals, erasures, or irregularities of any kind, excepting that erasures or
delineations in the proposal will be accepted as provided under "Bid Forms" above.
When proposals are signed by an agent, other than the officer or officers of a corporation authorized to sign
Contracts on its behalf or a member of a co-partnership, a Power of Attorney must be on file with the City
prior to opening proposals or must be submitted with the proposal; otherwise, the proposal may be rejected
as irregular and unauthorized.
Bid Security. All proposals must be presented under sealed cover and accompanied by one of the following
forms of bidder's security: Cashier's check, certified check, or a bidder's bond in the form provided herein,
executed by an admitted surety insurer authorized to transact business in this State, made payable to the City.
The submitted bidder's bond must be the City's bid bond. The security must be in an amount equal to at least
ten percent (10%) of the proposal amount. A proposal will not be considered unless one of the forms of
bidder's security is enclosed with it. A bidder's bond will not be accepted unless it has been properly filled
out and executed by both the surety and the bidder.
Withdrawal of Bid. Any bid may be withdrawn at any time prior to the time fixed in the public notice for
the opening of proposals only by a written request for withdrawal of the bid filed with the City Engineer. The
request must be executed by the bidder or its duly authorized representative. The withdrawal of a bid does
Well Nos. 33, 35 and 40 Rehabilitation Project Part 1: Bid Documents
City of Rohnert Park Page 1-3
OAK #4873-5882-6144 v1 (Rev. 1-24)

not prejudice the right of the bidder to file a new bid. No bid may be withdrawn after the time fixed in the
public notice for the opening of bids.
Means of Submittal. Proposals may be submitted by e-mail or hard copy; however, proposals failing to
reach the office of the City prior to the date and time set for receipt of same will not be considered.
Multiple Proposals. More than one proposal from an individual, a firm, partnership, corporation or an
association under the same or different names, will not be considered. Reasonable grounds for believing that
any bidder is interested in more than one proposal for the work contemplated will cause the rejection of all
proposals in which such bidder is interested. If there is reason for believing that collusion exists among the
bidders, none of the participants in such collusion will be considered in this or future proposals. Proposals in
which the prices obviously are unbalanced may be rejected.
License Requirement. No proposal will be accepted from a Contractor who is not licensed in accordance
with law under the provisions of Division III, Chapter 9, of the Business and Professions Code of the State
of California, or from a Contractor that has been deemed irresponsible or unresponsive.
Subcontractors. Subcontractors listed by the bidder in accordance with the Special Provisions included
herein must be properly licensed under the laws of the State of California for the type of work which they are
to perform.
All bidders are hereby notified that they will be required to comply strictly with the provisions of
Sections 4100 to 4113, inclusive, of the California Public Contract Code.
Each bidder must file with its proposal the name and location of the place of business, contractor's license
number and Department of Industrial Relations registration number, of each Subcontractor who will perform
a portion of the Contract work in an amount in excess of one-half of one percent (0.5%), or in the case of
bids for the construction of streets or highways, including bridges, in excess of one-half of one percent
(0.5%) of the total bid or ten thousand dollars ($10,000). In each such instance, the nature and extent of the
work to be sublet must be described.
The General Contractor to whom the Contract is awarded will not be permitted, without the written consent
of the City, to substitute any person as Subcontractor in place of the Subcontractor designated in the original
proposal, or to permit any Subcontract to be assigned or transferred, or to allow it to be performed by anyone
other than the original Subcontractor. The City may consent to the substitution of another person as
Subcontractor if the original Subcontractor, after having reasonable opportunity to do so, fails or refuses to
execute the written Contract presented to it by the General Contractor, when said written Contract is based
upon the conditions of the general Contract and complies with the Subcontractor's written proposal.
The failure of the Contractor to specify a Subcontractor for any portion of the Contract work in excess of one-
half of one percent (0.5%) of the total Contract price must be deemed to indicate that the Contractor intends
to perform such portion itself. The subletting or Subcontracting of work for which no Subcontractor was
designated in the original proposal and which is in excess of one-half of one percent (0.5%) of the total
Contract price will be allowed only with the written consent of the City and then only in cases of public
emergency or necessity as determined by the City. Under such circumstances, the City is required to establish
the facts constituting the emergency or necessity and to reduce its findings to a written public record.
Violations of the provisions of these specified sections of the Code must be deemed to be a violation of the
Contract, and the City, because of any such violations, may cancel the Contract. The Contractor, after any
such violations, will be penalized up to twenty percent (20%) of the amount of the Subcontract involved.
Material. The bidder may be required to furnish, as part of the submittal process, a complete statement of
the origin, composition, and manufacture of any or all materials to be used in the construction of the work,
together with samples. Such samples may be subjected to the tests provided for in these specifications or in
