CORONER
BACKGROUND
I
In accordance with the County's Strategic Energy Plan to implement on-site generation opportunities,
this project will install a 150kW cogeneration plant at the Martinez Detention Facility. The plant will
generate electricity for internal use and offset natural gas use for domestic hot water and space heat.
The completed project will cut energy costs by an estimated $65,000 per year.
I
Bid documents and specifications have been prepared by Axiom Engineers and filed with the Clerk of
the Board by the Director of General Services. The cost estimate for the work is $235,000, and the
prevailing rate of per diem wages is on file with the Clerk of the Board of Supervisors pursuant to the
statutes of the State of California and applicable local law, which shall be the minimum rates paid on
this project. I
Upon the Board's authorization, the General Services Director, or designee, will solicit bids from
qualified contractors in accordance with Section 4217.16 of the Government Code. Government
Code Section 4217.16 allows a Public Agency to request proposals from "qualified persons" for
energy projects and to award a contract based on cost, experience of the contractor, and other
relevant performance considerations. The General Services Department has established a list of
qualified contractors to seek bids from. Upon receipt of the bids, an evaluation will be conducted, and
a determination made based on the best combination of cost, contractor experience and
qualifications. The contract award recommendation will be brought before the Board at a future date.

3. WORK CONTRACT,CHANGES. (a) By their signatures in Section 2,effective on the above date,these parties promise and agree as
set forth in this contract,incorporating by these references the material("special terms")in Section 1.
(b) Contractor shall,at his own cost and expense,and in a workmanlike manner,fully and faithfully perform and complete the work;and
will furnish all materials, labor, services and transportation necessary, convenient and proper in order fairly to perform the requirements of this
contract,all strictly in accordance with the Public Agency's plans,drawings and specifications. ,
(c) The work can be changed only with Public Agency's prior written order specifying such change and its cost agreed to by the parties;
and the Public Agency shall never have to pay more than specified in Section 7 without such an order.
4. TIME: NOTICE TO PROCEED. Contractor shall start this work as directed in the specifications or the Notice to Proceed; and shall ,
complete it as specified in Section 1.
5. LIQUIDATED DAMAGES. If the Contractor fails to complete this contract and this work within the time fixed therefor, allowance
being made for contingencies as provided herein,he becomes liable to the Public Agency for all its loss and damage therefrom;and because,from the
nature of the case, it is and will be impracticable and extremely difficult to ascertain and fix the Public Agency's actual damage from any delay in
performance hereof, it is agreed that Contractor will pay as liquidated damages to the Public Agency the reasonable sum specified in Section 1,the
result of the parties'reasonable endeavor to estimate fair average compensation therefor,for each calendar day's delay in finishing said work; and if
the same be not paid,Public Agency may,in addition to its other remedies,deduct the same from any money due or to become due Contractor under
this contract. If the Public Agency for any cause authorizes or contributes to a delay,suspension of work or extension of time, its duration shall be
added to the time allowed for completion, but it shall not be deemed a waiver nor be used to defeat any right of the Agency to damages for non-
completion or delay hereunder. Pursuant to Government Code Section 4215, the Contractor shall not be assessed liquidated damages for delay in
completion of the work,when such delay was caused by the failure of the Public Agency or the owner of a utility to provide for removal or relocation
of existing utility facilities. '
6. INTEGRATED DOCUMENTS. The plans, drawings and specifications or special provisions of the Public Agency's call for bids, and
Contractor's accepted bid for this work are hereby incorporated into this contract;and they are intended to cooperate,so that anything exhibited in the
plans or drawings and not mentioned in the specifications or special provisions, or vice versa, is to be executed as if exhibited, mentioned and set
forth in both,to the true intent and meaning thereof when taken all together; and differences of opinion concerning these shall be finally determined
by Public Agency's Agent specified in Section 1.
7. PAYMENT. (a) For his strict and literal fulfillment of these promises and conditions, and as full compensation for all this work, the
Public Agency shall pay the Contractor the sum specified in Section 1,except that in unit price contracts the payment shall be for finished quantities
at unit bid prices.
(b) On or about the first of each calendar month,the Contractor shall be paid for all work done through the 15th of the preceding calendar
month,as determined by Public Agency or its Agent,minus 10%thereof pursuant to Public Contract Code Section 9203,but not until defective work
and materials have been removed,replaced,and made good.
8. PAYMENTS WITHHELD. (a) The Public Agency or its Agent may withhold any payment, or because of later discovered evidence
nullify all or any certificate for payment,to such extent and period of time only as may be necessary to protect the Public Agency from loss because
of:
(1) Defective work not remedied,or uncompleted work,or
(2) Claims filed or reasonable evidence indicating probable filing,or
(3) Failure to properly pay subcontractors or for material or labor,or
(4) Reasonable doubt that the work can be completed for the balance then unpaid,or ,
(5) Damage to another contractor,or
(6) Damage to the Public Agency,other than damage due to delays.
(b) The Public Agency shall use reasonable diligence to discover and report to the Contractor, as the work progresses, the materials and
labor which are not satisfactory to it,so as to avoid unnecessary trouble or cost to the Contractor in making good any defective work or parts..
(c) 35 calendar days after the Public Agency files its notice of completion of the entire work,it shall issue a certificate to the Contractor
and pay the balance of the contract price after deducting all amounts withheld under this contract,provided the Contractor shows that all claims for
labor and materials have been paid,no claims have been presented to the Public Agency based on acts or omissions of the Contractor,and no liens or
withhold notices have been filed against the work or site,and provided there are not reasonable indications of defective or missing work or of late-
recorded notices of liens or claims against Contractor.
9. INSURANCE. (Labor Code Sections 1860-61) On signing this contract,Contractor must give Public Agency(1)a certificate of consent
to self-insure issued by the Director of Industrial Relations,or(2)a certificate of Workers'Compensation insurance issued by an admitted insurer,or
(3)an exact copy or duplicate thereof certified by the Director or the insurer. Contractor is aware of and complies with Labor Code Section 3700 and
the Workers'Compensation Law.
10. BONDS. On signing this contract Contractor shall deliver to Public Agency for approval good and sufficient bonds with sureties, in
amount(s)specified in the specifications or special provisions,guaranteeing his faithful performance of this contract and his payment for all labor and
materials hereunder.
11. FAILURE TO PERFORM. If the Contractor at any time refuses or neglects,without fault of the Public Agency or its agent(s),to supply
sufficient materials or workers to complete this agreement and work as provided herein,for a period of 10 days or more after written notice thereof
by the Public Agency,the Public Agency may furnish same and deduct the reasonable expenses thereof from the contract price.

Chapter 1 of Part 7 of the California Labor Code (beginning with Section 1720, and including Sections 1735, 1777.5, & 1777.6 forbidding
discrimination) and intend that this agreement complies therewith. The parties specifically stipulate that the relevant penalties and forfeitures
provided in the Labor Code, especially in Sections 1775 & 1813, concerning prevailing wages and hours, shall apply to this agreement as though
fully stipulated herein.
13. SUBCONTRACTORS. Public Contract Code Sections 4100-4114 are incorporated herein.

classification,or type of worker needed to execute this contract,and said rates are as specified in the call for bids for this work or are on file with the
Public Agency,and are hereby incorporated herein.
(b) This schedule of wages is based on a working day of 8 hours unless otherwise specified;and the daily rate is the hourly rate multiplied by
the number of hours constituting the working day. When less than that number of hours are worked,the daily wage rate is proportionately reduced,
but the hourly rate remains as stated.
(c) The Contractor, and all his subcontractors, must pay at least these rates to all persons on this work, including all travel, subsistence, and
fringe benefit payments provided for by applicable collective bargaining agreements. All skilled labor not listed above must be paid at least the wage
' scale established by collective bargaining agreement for such labor in the locality where such work is being performed. If it becomes necessary for
the Contractor or any subcontractor to employ any person in a craft, classification or type of work(except executive, supervisory, administrative,
clerical or other non-manual workers as such) for which no minimum wage rate is specified, the Contractor shall immediately notify the Public
Agency which shall promptly determine the prevailing wage rate therefor and furnish the Contractor with the minimum rate based thereon, which
shall apply from the time of the initial employment of the person affected and during the continuance of such employment.
15. HOURS OF LABOR. Eight hours of labor in one calendar day constitutes a legal day's work,and no worker employed at any time on this
work by the Contractor or by any subcontractor shall be required or permitted to work longer thereon except as provided in Labor Code Sections
1810-1815.
16. APPRENTICES. Properly indentured apprentices may be employed on this work in accordance with Labor Code Sections 1777.5 and
1777.6,forbidding discrimination.

Contractor therefore promises to use the products,workers, laborers and mechanics of this County in every case where the price, fitness and quality
are equal. 1
18. ASSIGNMENT. The agreement binds the heirs, successors, assigns, and representatives of the Contractor; but he cannot assign it in
whole or in part,nor any monies due or to become due under it,without the prior written consent of the Public Agency and the Contractor's surety or
sureties,unless they have waived notice of assignment. I
19. NO WAIVER BY PUBLIC AGENCY. Inspection of the work and/or materials, or approval of work and/or materials inspected, or
statement by any officer, agent or employee of the Public Agency indicating the work or any part thereof complies with the requirements of this
contract, or acceptance of the whole or any part of said work and/or materials, or payments therefor, or any combination of these acts, shall not
relieve the Contractor of his obligation to fulfill this contractlas prescribed;nor shall the Public Agency be thereby estopped from bringing any action
for damages or enforcement arising from the failure to comply with any of the terms and conditions hereof.
1
20. HOLD HARMLESS & INDEMNITY. (a)Contractor promises to and shall hold harmless and indemnify from the liabilities as defined

law or equity concerning these.
I

and attributable to the Contractor,subcontractor(s),or any off cer(s),agent(s)or employee(s)of one or more of them.

prepared,supplied,or approved any plan(s),drawing(s),specification(s)or special provision(s)in connection with this work,has insurance or other
indemnification covering any of these matters,or that the alleged damage resulted partly from any negligent or willful misconduct of any indemnitee.
