INSTRUCTIONS TO BIDDERS
1. BID FORMAT
Each Bid must be submitted in a sealed envelope, addressed to the Owner at the office where
bids will be received as stated in the Notice Inviting Bids. Each sealed envelope containing a Bid
must be plainly marked on the outside as BID FOR BOX CANYON GENERATOR REPLACEMENT
PROJECT, and the envelope should bear on the outside the name of the Bidder and its address.
All Bids shall be made on the required Bid form(s). All blank spaces for Bid prices shall be filled
in, in ink or typewritten, and the Bid form(s) shall be fully completed and executed when
submitted. Any corrections to entries made on Bid form(s) shall be initialed in ink by the person
signing the Bid. In case of discrepancy between unit prices and total shown in the Bid, unit
prices shall prevail. Only one copy of the Bid form(s) is required unless otherwise specified.
Additional sheets required to fully respond to requested information are permissible. All items
listed on the Bidder's Checklist shall be included to constitute a complete Bid.
The Owner may waive any informalities or minor defects or reject any and all Bids. Any Bid may
be withdrawn either personally or by written request prior to the above-scheduled time for the
opening of Bids or authorized postponement thereof. Modifications to Bids already submitted
will be allowed if received in writing prior to the time fixed in the Notice Inviting Bids for
opening of Bids. Any Bid received after the time and date specified shall be returned unopened
and not be considered.
2. BIDDER'S UNDERSTANDING
Bidders must satisfy themselves as to the accuracy of the estimated quantities in the Bid
Schedule by examination of the site and a review of the Contract Documents. If the Bidder
determines any errors or inaccuracies in the Contract Documents, the Bidder shall immediately
notify the Engineer. After Bids have been submitted, the Bidder shall not assert that there was
a misunderstanding concerning the quantities of work or of the nature of the work to be done.
Each Bidder is responsible for inspecting the site and for reading and being thoroughly familiar
with the Contract Documents. The failure or omission of any Bidder to do any of the foregoing
shall in no way relieve any Bidder from any obligation with respect to its Bid.
The Contract Documents contain the provisions required for the construction of the Project.
Information obtained from an officer, agent, or employee of the Owner or the Engineer or any
other person shall not affect the risks or obligations assumed by the Contractor or relieve them
from fulfilling any of the conditions of the Contract.
All information or responses of a Bidder in its Bid and other documents accompanying the Bid
shall be complete, accurate and true. Incomplete, inaccurate, or untrue responses or
information provided therein by a Bidder shall be grounds for the Owner to reject such Bidder's
Bid, in the Owner's sole discretion, for nonresponsiveness.
0470.19 2000-1

Bidders are solely responsible for the cost of preparing their bids.
3. BID GUARANTEE; PERFROMANCE AND PAYMENT BONDS
Each Bid must be accompanied by a Bid Guarantee, consisting of a Bid Bond payable to the
Owner. The Bid Guarantee shall be in the amount of ten percent (10%) of the total amount of
the Bid. As soon as the Bid prices have been compared, the Owner will, upon written request,
return the Bid Guarantees of all except the three lowest responsible Bidders. When the
Contract is executed, the Bid Guarantees of the two remaining unsuccessful Bidders will be
returned, upon written request. The Bid Guarantee of the successful Bidder will be retained
until the Payment Bond and the Performance Bond have been executed and approved, after
which it will be returned. Unless specifically requested by Bidders in writing, Bid Bonds will not
be returned, but will be considered void and will be destroyed when Bid Guarantees would
have otherwise been returned. A Bidder's Bond will be accepted only if it is made out on either
the Bidder's Bond form enclosed in these Documents or on a form that conforms to it. The
bonds must be executed by a duly licensed surety company which is listed in the latest
circular 570 of the United States Treasury Department as being acceptable as a surety on
federal bonds.
A Performance Bond and a Payment Bond, each in the amount of 100% of the total contract
amount as stipulated in the General Provisions, will be required for the faithful performance of
the Contract. The Performance Bond shall remain in effect until the end of all warranty periods
set forth in the Contract Documents.
Attorneys-in-fact who sign Bid Bonds or Payment Bonds and Performance Bonds must file with
each Bond a certified and effective dated copy of their power of attorney.
4. EVALUATION OF BIDS
Owner reserves the right to reject any or all Bids, including without limitation, nonconforming,
nonresponsive, unbalanced, or conditional Bids. Owner also reserves the right to waive all
minor Bid informalities not involving price, time, or changes in the Work.
Owner will reject the Bid of any Bidder that Owner finds, after reasonable inquiry and
evaluation, to not be responsible.
If Bidder purports to add terms or conditions to its Bid, takes exception to any provision of the
Bidding Documents, or attempts to alter the contents of the Contract Documents for purposes
of the Bid, whether in the Bid itself or in a separate communication to Owner or Engineer, then
Owner will reject the Bid as nonresponsive.
Evaluation of Bids:
1. In evaluating Bids, Owner will consider whether the Bids comply with the prescribed
requirements, and such alternates, unit prices, and other data, as may be requested in
the Bid or prior to the Notice of Award.
2. Award will be made to the lowest overall responsible Bidder based on the Base Bid
amount, subject to satisfaction of the conditions described above.
0470.19 2000-2

In evaluating whether a Bidder is responsible, Owner will consider the qualifications of the
Bidder and may consider the qualifications and experience of Subcontractors and Suppliers
proposed for those portions of the Work for which the identity of Subcontractors and Suppliers
must be submitted as provided in the Bidding Documents.
Owner may conduct such investigations as Owner deems necessary to establish the responsibility,
qualifications, and financial ability of Bidders and any proposed Subcontractors or Suppliers.
5. AWARD OF CONTRACT
No Bidder may withdraw a Bid within sixty (60) days after the actual date of the opening
thereof. Should there be reasons why the Contract cannot be awarded within the specified
period, the time may be extended by mutual agreement between the Owner and the Bidder.
The party to whom the Contract is awarded will be required to execute the Contract and obtain
the Performance Bond, Payment Bond, and insurance certificates as specified in the Contract
Documents within fifteen (15) calendar days from the date when Notice of Award is delivered
to the Bidder. The Notice of Award shall be accompanied by the necessary Contract and Bond
forms. In case of failure of the Bidder to execute the Contract, the Owner may, at its option,
consider the Bidder in default, in which case the Bid Guarantee accompanying the Bid shall
become the property of the Owner.
The Owner, within twenty-one (21) calendar days of receipt of acceptable Performance Bond,
Payment Bond, Contract signed by the party to whom the Contract was awarded, and insurance
certificates, shall sign the Contract and return to such party an executed duplicate of the
Contract. Should the Owner not execute the Contract within such period, the Bidder may by
written notice withdraw their signed Contract. Such notice of withdrawal shall be effective
upon receipt of the notice by the Owner.
The Contract Times will commence to run on the 30th day after the Effective Date of the
Contract or, if a Notice to Proceed is given, on the day indicated in the Notice to Proceed. A
Notice to Proceed may be given at any time within 30 days after the Effective Date of the
Contract.
The Owner may make such investigations as he deems necessary to determine the ability of the
Bidder to perform the work, and the Bidder shall furnish to the Owner all such information and
data for this purpose as the Owner may request. The Owner reserves the right to reject any Bid
if the evidence submitted by, or investigation of, such Bidder fails to satisfy the Owner that such
Bidder is properly qualified to carry out the obligations of the Contract and to complete the
work contemplated therein.
The Contract is to be awarded to the responsive, responsible bidder with the lowest total of the
base bid.
0470.19 2000-3

If, at the time this Contract is to be awarded, the total of the lowest responsive Bid exceeds the
funds then estimated by the Owner as available, the Owner may reject all bids or take such
other action as best serves the Owner's interests.
6. LIST OF SUBCONTRACTORS AND REGISTRATION
As stipulated in the General Provisions, Section 1-6.2, each Bidder shall submit with their Bid a
list showing the name, address, and type of work to be performed by each subcontractor who
will be employed by the Contractor in performance of the work in the amount of more than
one-half of one percent of the total Contract amount("Subcontractors List"). If the Bidder fails
to specify a subcontractor for any portion of the work to be performed under the Contract, the
Bidder agrees to perform that portion of the work itself.
An inadvertent error in listing the California contractor license number on the Subcontractors
List shall not be grounds for filing a Bid protest or grounds for considering the Bid nonresponsive
if the correct contractor's license number is submitted to the Owner within 24 hours after the
bid opening and the corrected number corresponds with the submitted name and location for
that subcontractor.
No Contractor or subcontractor may be listed on a Bid for a public works project unless
registered with the Department of Industrial Relations pursuant to Labor Code Section 1725.5
with limited exceptions from this requirement for bid purposes only under Labor Code
Section 1771.1(a). The subcontractor's registration must remain active throughout the term of
the Contract.
No Contractor or subcontractor may be awarded a Contract for public work on a Public Works
project unless registered with the Department of Industrial Relations pursuant to Labor Code
section 1725.5.
This project is subject to compliance monitoring and enforcement by the Department of
Industrial Relations.
An inadvertent error listing an unregistered subcontractor shall not be grounds for filing a bid
protest or grounds for considering the bid nonresponsive provided that any of the following
apply:
1. The subcontractor is registered prior to the bid opening.
2. The subcontractor is registered and has paid the penalty registration fee within 24 hours
after the bid opening.
3. The subcontractor is replaced by another registered subcontractor pursuant to Public
