separate document, headed, "DONATED MATERIALS":
1. Name of subcontractor or supplier making the donation;
2. Materials donated;
3. Approximate value of donated materials.
The unit and extended prices set forth in the bid form should reflect the reduced cost resulting from the donated
materials.
The City has available for the construction of this project a total of $750,000. The City has not identified any
deductive alternates that could be used to reduce the potential cost of the project. Nevertheless, the City has
elected to issue this Notice Inviting Bids for the construction of this project. PLEASE BE ADVISED that the City
reserves the right to reject any or all bids for any reason, including, but not limited to, if the lowest responsive
and responsible bid exceeds the available funding.

and labor required so that he or she may fully understand the facilities, difficulties and restrictions attending the
execution of the work under the Contract. Bidders shall thoroughly examine and be familiar with the Plans and
1 Special Provisions. The failure of any bidder to receive or examine any form, instrument, addendum, or other
document, and acquaint himself with conditions there existing, shall in no way relieve the bidder from any obligation
with respect to his or her proposal or to the contract. The drawings for the work show conditions as they are
1 supposed or believed by the City to exist; but, it is neither intended nor shall it be inferred that the conditions as
l shown thereon constitute a representation by the City or its officers that such conditions are actually existent, nor
shall the City, or any of their officers or representatives be liable for any loss sustained by the Contractor as a result
of a variance between the conditions shown on the drawings and the conditions actually revealed during the
progress of the work or otherwise.

thereto, which may or may not be shown on the Drawings.
The bidder shall investigate to his or her satisfaction the conditions to be encountered, the character, quality and
quantities of work to be performed and materials to be furnished and the requirements of the Plans, Special
Provisions, Standard Specifications, Standard Plans, and Contract Documents. The submission of a proposal shall
be considered conclusive evidence that the bidder has made such examination and has accepted the project
workplace as a safe workplace to perform the work of the Contract.

such timely written protest is filed, all bidders shall be provided a copy of the protest within 2 calendar days of its

construction, meaning and intent of the Special Provisions and Drawings, (3) shall decide all questions which may
arise relative to the classifications and measurements of quantities and materials and the fulfillment of this
contract and (4) shall have the power to reject or condemn all work or material which does not conform to the
terms of this contract. his or her estimate and decision in all matters shall be a condition precedent to an appeal
for arbitration, or the right of the Contractor to receive, demand, or claim any money or other compensation under
this agreement and a condition precedent to any liability on the part of the City to the Contractor on account of this
contract. Whenever the Owner's Representative shall be unable to act, in consequence of absence or other
cause, then such Owner's Representative as the Owner's Representative or the City shall designate, shall
perform any and all of the duties and be vested with any or all of the powers herein given to the Owner's
Representative.
7-02. Inspection. The City will not be providing engineering personnel for the inspection of the work.
The Owner's Representative and his or her representatives shall at all times have access to the work whenever it
is in preparation or progress and the Contractor shall provide proper facilities for such access and inspection.
Ukiah Skate Park 12 Spec. No. 10-02
If the Special Provisions, the Owner's Representative's instruction, laws, ordinances, or any public authority
requires any work to be specially tested or approved, the Contractor shall give the Owner's Representative timely
notice of its readiness for inspection and, if the inspection is by an authority other than the Owner's
Representative, of the date fixed for such inspection. Inspections by the Owner's Representative shall be promptly
made at the source of supply where practicable. If any work shall be covered up without approval or consent of
the Owner's Representative, it must, if required by the Owner's Representative, be uncovered for examination
and properly restored at the Contractor's expense.
Re-examination of any work may be ordered by the Owner's Representative and, if so ordered, the work must be
uncovered by the Contractor. If such work is found to be in accordance with the contract documents, the City shall
pay the cost of re-examination and replacement. If such work is not in accordance with the contract documents,
the Contractor shall pay such cost.
Properly authorized and accredited inspectors shall be considered to be the representatives of the City limited to
the duties and powers entrusted to them. It will be their duty to inspect materials and workmanship of those
I portions of the work to which they are assigned, either individually or collectively, under instructions of the
Owner's Representative and to report any and all deviations from the Drawings, Special Provisions and other
contract provisions which may come to their notice. Any inspector may be considered to have the right to order
1 the work entrusted to his or her supervision stopped, if in his or her opinion such action becomes necessary, until
J the Owner's Representative is notified and has determined and ordered that the work may proceed in due
fulfillment of all contract requirements.
7-03. Surveys. Contractor shall furnish all land surveys, establish all base lines and bench marks and make
sufficient detailed surveys needed for working points, lines and elevations. The Contractor shall develop all slope
stakes and batter boards. Contractor shall also develop all additional working points, lines and elevations as he or
she may desire to facilitate his or her methods and sequence of construction.
7-04. Rights-of-Way. The City will provide all necessary rights-of-way and easements in or beneath which work
will be performed by the Contractor under this contract.
7-05. Retention of Imperfect Work. If any portion of the work done or material furnished under this contract
shall prove defective and not in accordance with the Plans and Special Provisions, and if the imperfection in the
same shall not be of sufficient magnitude or importance to make the work dangerous or undesirable, the Owner's
Representative shall have the right and authority to retain such work instead of requiring the imperfect work to be
removed and reconstructed, but he or she shall make such deductions therefore in the payments due or to
become due the Contractor as may be just and reasonable.
7-06. Changes in the Work. The Owner's Representative shall have the right, in writing, to order additions to,
omissions from, or corrections, alterations and modifications in the line, grade, form, dimensions, plan, or kind or
amount of work or materials herein contemplated, or any part thereof, either before or after the beginning of
construction. However, the arithmetical sum of the cost to the City of additions and subtractions from the work
under this contract shall not exceed 10 percent of original contract amount or $5,000, whichever is the greater,
unless based upon a supplementary agreement to be made therefore.
The order of such additions, omissions, corrections, alterations and modifications shall be in writing and signed by
the Owner's Representative and, in order, shall then be binding upon the Contractor. The Contractor shall
proceed with the work as changed and the value of such change shall be determined as provided for in section
10-07 of these Special Provisions.
Such alterations shall in no way affect, vitiate, or make void this contract or any part thereof, except that which is
necessarily affected by such alterations and is clearly the evident intention of the parties to this contract.
7-07. Additional Drawings by City. The drawings made a part of this contract at the time of its execution are
intended to be fairly comprehensive and to indicate in more or less detail the scope of the work. In addition to
these drawings, however, the Owner's Representative shall furnish such additional drawings from time to time
during the progress of the work as are necessary to make clear or to define in greater detail the intent of the
Special Provisions and the contract drawings and the Contractor shall make his or her work conform to all such
drawings.
Ukiah Skate Park 13 Spec. No. 10-02
7-08. Additional and Emergency Protection. Whenever, in the opinion of the Owner's Representative, the
Contractor has not taken sufficient precautions for the safety of the public or the protection of the works to be
constructed under this contract, or of adjacent structures or property which may be injured by the processes of
construction on account of such neglect and whenever, in the opinion of the Owner's Representative, an
emergency shall arise and immediate action shall be considered necessary in order to protect public or private,
personal or property interest, then and in that event, the Owner's Representative, with or without notice to the
Contractor may provide suitable protection to the said interests by causing such work to be done and such
material to be furnished as shall provide such protection as the Owner's Representative may consider necessary
and adequate.
The cost and expense of such work and material so furnished shall be borne by the Contractor and, if the same
shall not be paid on presentation of the bills therefore, then such costs shall be deducted from any amounts due
or to become due the Contractor.
The performance of such emergency work under the direction of the Owner's Representative shall in no way
relieve the Contractor from any damages which may occur during or after such precaution has been taken bythe
Owner's Representative.
7-09. Suspension of Work. The City may at any time suspend the work or any part thereof by giving five (5)
days written notice to the Contractor. The work shall be resumed by the Contractor within ten (10) days after the
date fixed in the written notice from the City to the Contractor. The City shall reimburse the Contractor for expense
incurred by the Contractor in connection with the work under this contract as a result of such suspension.
If the work, or any part thereof, shall be stopped by the notice in writing aforesaid and if the City does not give
notice in writing to the Contractor to resume work at a date within ten (10) days of the date fixed in the written
notice to suspend, then the Contractor may abandon that portion of the work so suspended and he or she will be
entitled to the estimates and payments for all work done on the portions so abandoned, if any, plus 5 percent of
the value of the work so abandoned, to compensate for loss of overhead, plant expense and anticipated profit.
7-10. Right of City to Terminate Contract. If the Contractor should be adjudged a bankrupt, or if he or she
should make a general assignment for the benefit of his or her creditors, or if a receiver should be appointed on
account of his or her insolvency, or if he or she should persistently or repeatedly refuse or should fail, except in
cases for which extension of time is provided, to supply sufficient properly skilled workmen or proper materials, or
if he or she should fail to make prompt payments to subcontractors or for material or labor, or persistently
disregard laws, ordinances or the instructions of the Owner's Representative, or otherwise be guilty of a
substantial violation of any provision of the contract, then the City, upon the certificate of the Owner's
Representative that sufficient cause exists to justify such action, may, without prejudice to any other right or
remedy and after giving the Contractor seven days written notice, terminate the employment of the Contractor and
take possession of the premises and of all materials, tools and appliances and finish the work by whatever
method the City may deem expedient. In such case, the Contractor shall not be entitled to receive any further
payment until the work is finished. If the unpaid balance of the contract price shall exceed the expense of finishing
the work, including compensation for additional managerial and administrative services, such excess shall be paid
to the Contractor. If such expense shall exceed such unpaid balance, the Contractor shall pay the difference to
the City. The expense incurred by the City as herein provided and the damage incurred through the Contractor's
default, shall be certified by the Owner's Representative.
7-11. Use of Completed Portions. The City shall have the right to take possession of and use any completed or
partially completed portions of the work, notwithstanding the time for completing the entire work or such portions
which may not have expired; but such taking possession and using shall not be deemed an acceptance of any
work not completed in accordance with the contract documents. If such prior use increases the cost of or delays
the work, the Contractor shall be entitled to such extra compensation, or extension of time or both, as the Owner's
Representative may determine.
SECTION 8. WORKMANSHIP, MATERIALS and EQUIPMENT
8-01. General Quality. Materials and equipment shall be new and of a quality equal to that specified or
approved. Work shall be done and completed in a thorough and workmanlike manner.
Ukiah Skate Park 14 Spec. No. 10-02
8-02. Quality in Absence of Detailed Specifications. Whenever under this contract it is provided that the
Contractor shall furnish materials or manufactured articles or shall do work for which no detailed specifications
are set forth, the materials or manufactured articles shall be of the best grade in quality and workmanship
r l obtainable in the market from firms of established good reputation, or, if not ordinarily carried in stock, shall
l conform to the usual standards for first-class materials or articles of the kind required, with due consideration of
the use to which they are to be put. In general, the work performed shall be in full conformity and harmony with
the intent to secure the best standard of construction and equipment of the work as a whole or in part.
8-03. Materials and Equipment Specified by Name. Whenever any material or equipment is indicated or
specified by patent or proprietary name or by the name of the manufacturer, such specification shall be
considered as used for the purpose of describing the material or equipment desired and shall be considered as
followed by the words "or approved equal". The Contractor may offer any material or equipment which shall be
equal in every respect to that specified, provided that written approval first is obtained from the Owner's
Representative.
8-04. Source of Materials. Price, fitness and quality being equal, preference shall be given by the Contractor for
supplies grown, manufactured or produced in the State of California and, next, for such products partially
produced in this State in accordance with Government Code Section 4332.
8-05. Storage of Materials. Materials shall be so stored to ensure the preservation of their quality and fitness for
the work. They shall be so located and disposed that prompt and proper inspection thereof may be made.
8-06. Drawings, Samples and Tests. As soon as possible after execution of the contract, the Contractor shall
submit to the Owner's Representative, in quintuplicate, sufficient information including, if necessary, assembly
and detail drawings to demonstrate fully that the equipment and materials to be furnished comply with the
provisions and intent of these Special Provisions and Drawings. If the information thus submitted indicates the
equipment or materials is acceptable, the Owner's Representative will return one copy stamped with his or her
approval; otherwise, one copy will be returned with an explanation of why the equipment or material is
unsatisfactory. The Contractor shall have no claims for damages or for extension of time on account of any delay
due to the revision of drawings or rejection of material. Fabrication or other work performed in advance of
approval shall be done entirely at the Contractor's risk. After approval of equipment or material, the Contractor
shall not deviate in any way from the design and specifications given without the written consent of the Owner's
Representative.
When requested by the Owner's Representative, a sample or test specimens of the materials to be used or
offered for use in connection with the work shall be prepared at the expense of the Contractor and furnished by
him or her in such quantities and sizes as may be required for proper examination and tests, with all freight
charges prepaid and with information as to their sources.
All samples shall be submitted before shipment and in ample time to permit the making of proper tests, analyses,
or examination before the time at which it is desired to incorporate the material into the work. All tests of materials
furnished by the Contractor shall be made by the Owner's Representative. Samples shall be secured and tested
whenever necessary to determine the quality of the material.
SECTION 9. PROSECUTION OF WORK
9-01. Equipment and Methods. The work under this contract shall be prosecuted with all materials, tools,
machinery, apparatus and labor and by such methods as are necessary to the complete execution of everything
described, shown, or reasonably implied. If at any time before the beginning or during the progress of the work,
any part of the Contractor's plant or equipment, or any of his or her methods of execution of the work, appear to
the Owner's Representative to be unsafe, inefficient, or inadequate to insure the required quality or the rate of
progress of the work, he or she may order the Contractor to increase or improve his or her facilities or methods
and the Contractor shall comply promptly with such orders; but, neither compliance with such orders norfailure of
the Owner's Representative to issue such orders shall relieve the Contractor from his or her obligation to secure
the degree of safety, the quality of the Work and the rate of progress required of the Contractor. The Contractor
alone shall be responsible for the safety, adequacy and efficiency of his or her plant, equipment and methods.
1 Ukiah Skate Park 15 Spec. No. 10-02
9-02. Time of Completion. The Contractor shall promptly begin the work under this contract and shall complete
and make ready for full use all portions of the project made the subject of this contract within the time set forth in
the agreement bound herewith.
9-03. Avoidable Delays. Avoidable delays in the prosecution or completion of the work shall include all delays
which might have been avoided by the exercise of care, prudence, foresight and diligence on the part of the
Contractor. The City will consider as avoidable delays within the meaning of this contract (1) delays in the
prosecution of parts of the work, which may in themselves be unavoidable, but do not necessarily prevent or delay
the prosecution of other parts of the work nor the completion of the whole work within the time herein specified,
(2) reasonable loss of time resulting from the necessity of submitting plans to the Owner's Representative for
approval and from the making of surveys, measurements, inspections, and testing and (3) such interruptions as
may occur in the prosecution of the work on account of the reasonable interference of other contractors employed
by the City which do not necessarily prevent the completion of the whole work within the time herein specified.
9-04. Unavoidable Delays. Unavoidable delays in the prosecution or completion of the work under this contract
shall include all delays which may result, through cause beyond the control of the Contractor and which he or she
could not have provided against by the exercise of care, prudence, foresight and diligence. Orders issued by the
City changing the amount of work to be done, the quantity of material to be furnished or the manner in which the
work is to be prosecuted and unforeseen delays in the completion of the work of other contractors under contract
with the City will be considered unavoidable delays, so far as they necessarily interfere with the Contractor's
completion of the whole of the work. Delays due to normally adverse weather conditions will not be regarded as
unavoidable delays. However, truly abnormal amounts of rainfall, temperatures or other weather conditions for the
location of the work and time of year may be considered as unavoidable delays if those conditions necessarily
cause a delay in the completion of the work.
9-05. Notice of Delays. Whenever the Contractor foresees any delay in the prosecution of the work and, in any
event, immediately upon the occurrence of any delay which the contractor regards as an unavoidable delay, he or
she shall notify the Owner's Representative in writing of the probability of the occurrence of such delay and its
cause, in order that the Owner's Representative may take immediate steps to prevent, if possible, the occurrence
or continuance of the delay, or, if this cannot be done, may determine whether the delay is to be considered
avoidable or unavoidable, how long it continues and to what extent the prosecution and completion of the work
are to be delayed thereby.
9-06. Extension of Time. Should any delays occur which the Owner's Representative may consider
unavoidable, as herein defined, the Contractor shall, pursuant to his or her application, be allowed an extension of
time proportional to said delay or delays, beyond the time herein set forth, in which to complete this contract; and
liquidated damages for delay shall not be charged against the Contractor by the City during an extension of time
granted because of unavoidable delay or delays.
Any claim by Contractor for a time extension based on unavoidable delays shall be based on written notice
delivered to the Owner's Representative within 15 days of the occurrence of the event giving rise to the claim.
Failure to file said written notice within the time specified shall constitute a waiver of said claim. Notice of the full
extent of the claim and all supporting data must be delivered to the Owner's Representative within 45 days of the
occurrence unless the Owner's Representative specifies in writing a longer period. All claims for a time extension
must be approved by the Owner's Representative and incorporated into a written change order.
9-07. Unfavorable Weather and Other Conditions. During unfavorable weather and other conditions, the
Contractor shall pursue only such portions of the work as shall not be damaged thereby. No portions of the work
whose satisfactory quality or efficiency will be affected by any unfavorable conditions shall be constructed while
these conditions remain, unless, by special means or precautions approved by the Owner's Representative, the
Contractor shall be able to overcome them.
The Contractor shall be granted a time extension of one day for each unfavorable weather day which prevents
him or her from placing concrete forms or placing and finishing concrete or asphalt concrete. Such unfavorable
weather day is defined as a rain day where precipitation prevents the contractor from performing the work more
than four (4) continuous hours within the authorized work period or a temperature day where the ambient
temperature is below that specified for the placement of materials associated with the controlling work item for
more than four (4) continuous work hours of the authorized work period.

9-08. Saturday, Sunday, Holiday and Night Work. No work shall be done between the hours of 6 p.m. and 7
a.m., nor on Saturdays, Sundays or legal holidays except such work as is necessary for the proper care and
protection of work already performed, or except in cases of absolute necessity and in any case only with the
permission of the Owner's Representative.
It is understood, however, that night work may be established as a regular procedure by the Contractor if he or
she first obtains the written permission of the Owner's Representative and that such permission may be revoked
at any time by the Owner's Representative if the Contractor fails to maintain at night adequate force and
equipment for reasonable prosecution and to justify inspection of the work.
9-09. Hours of Labor. Eight (8) hours of labor shall constitute a legal day's work and the Contractor or any
subcontractor shall not require or permit more than eight hours of labor in a day from any person employed by
him or her in the performance of the work under this contract, unless paying compensation for all hours worked in
excess of eight (8) hours per day at not less than 11/2 times the basic rate of pay. The Contractor shall forfeit to
the City, as a penalty, the sum of twenty-five dollars ($25.00) for each workman employed in the execution of the
contract by him or her or by any subcontractor, for each calendar day during which such laborer, workman, or
mechanic is required or permitted to labor more than eight hours in violation of the provisions of Section 1810 to
1816, inclusive, (Article 3, Chapter 1, Part 7, Division 2) of the Labor Code of the State of California and any acts
amendatory thereof.
SECTION 10. PAYMENT

presentation of certificates in writing from the Owner's Representative and shall show that the work covered by
the payments has been done and the payments thereof are due in accordance with this contract.
10-02. Progress Estimates and Payment. The Owner's Representative shall, within the first seven (7) days of
each month, make an estimate of the value of the work performed in accordance with this contract during the
previous calendar month.
The first estimate shall be of the value of the work satisfactorily completed in place and meeting the requirements
of the contract. And every subsequent estimate, except the final estimate, shall be of the value of the work
satisfactorily completed in place since the last preceding estimate was made; provided, however, that should the
Contractor fail to adhere to the program of completion fixed in this contract, the Owner's Representative shall
deduct from the next and all subsequent estimates the full calculated accruing amount of the liquidated damages
to the date of said estimate, until such time as the compliance with the program has been restored.
The estimate shall be signed by the Owner's Representative and, after approval, the City shall pay or cause to be
paid to the Contractor in the manner provided by law, an amount equal to 90 percent of the estimated value of the
work satisfactorily performed and complete in place.
10-03. Substitution of Securities.
1. At such times that Government Code Section 4590 is in effect Contractor may propose the substitution of
securities of at least equal market value for any moneys to be withheld to ensure performance under the Contract.
Market value shall be determined as of the day prior to the date such substitution is to take place. Such
substitution shall be made at the request and expense of the Contractor. The securities shall be one or more of

contract.
The market value of the securities deposited shall at all times be maintained in an amount at least equal, in the
sole judgment of City, to the moneys to be withheld pursuant to the Contract Documents to ensure performance

upon request by City or the escrow agent.
3. Upon acceptance of any Proposal that includes substituting securities for amounts withheld to ensure

himself as to the actual completion of the work in accordance with the terms of the contract and shall thereupon
recommend acceptance by the City Council.
10-05. Final Estimate and Payment. The Owner's Representative shall, as soon as practicable after the final
acceptance of the work done under this contract, make a final estimate of the amount of work done thereunder
and the value thereof.
Such final estimate shall be signed by the Owner's Representative, and after approval, the City shall pay or cause

deducting therefrom all previous payments and such other lawful amounts as the terms of this contract prescribe.
In no case will final payment be made in less than thirty-five (35) days after the filing of the notice of completion
with the County Recorder.
10-06. Delay Payments. Should any payment due the Contractor or any estimate be delayed, through fault of
the City beyond the time stipulated, such delay shall not constitute a breach of contract or be the basis for a claim
for damages, but the City shall pay the Contractor interest on the amount of the payment at the rate of 6 percent
per annum for the period of such delay. The terms for which interest will be paid shall be reckoned, in the case of
any monthly or progress payment, from the twentieth day of the month next succeeding the month in which the
work was performed to the date of payment of the estimate; and in the case of the final estimate, from the forty-
fifth day after acceptance to the date of payment of the final estimate.
The date of payment of any estimate shall be considered the day on which the payment is offered or mailed as
evidenced by the records of the Treasurer of the City. If interest shall become due on any delayed payment, the
amount thereof, as determined by the City, shall be added to a succeeding payment. If the interest shall become
due on the final payment, it shall be paid on a supplementary voucher to interest or any sum or sums which, by
the terms of this contract, the City is authorized to reserve or retain.
10-07. Extra Work and Work Omitted. Whenever corrections, alterations, or modifications of the work under
this contract ordered by the Owner's Representative and approved by the City increase the amount of work to be
done, such added work shall be known as "extra work"; and when such corrections, alterations, or modifications
decrease the amount of work to be done, such subtracted work shall be known as "work omitted".
When the Contractor considers that any changes ordered involve extra work, he or she shall immediately notify
the Owner's Representative in writing and subsequently keep him or her informed as to when and where extra
work is to be performed and shall make claim for compensation therefore each month not later than the first day
of the month following that in which the work claimed to be extra work was performed and he or she shall submit
a daily complete statement of materials and labor used and expenses incurred on account of extra work
performed, showing allocation of all materials, labor and expenses.
All such claims shall state the date of the Owner's Representative's written order and the date of approval by the
City authorizing the work on account of which claim is made. Unless such notification is made in writing within the
time specified and unless complete statements of materials used and expenses incurred on account of such extra
work are furnished as above required, the Contractor shall not be entitled to payment on account of extra work
and Contractor shall be deemed to have waived the right to make any future claims for compensation for such
extra work.
When changes decrease the amount of work to be done, they shall not constitute a claim for damages on
account of anticipated profits on the work that may be omitted.
} 10-08. Compensation for Extra Work or Work Omitted. Whenever corrections, additions, or modifications in
the work under this contract change the amount of work to be done or the amount of compensation due the
y Ukiah Skate Park 19 Spec. No. 10-02
Contractor, excepting increases or decreases in contract items having unit contract prices for each measurable
quantity installed in place, and such changes have been ordered in writing by the Owner's Representative and
approved by the City prior to the Contractor performing the extra work, then a price may be agreed upon. Failing
such an agreement in price, the Contractor shall be compensated for performing extra work pursuant to the
provisions of Section 4-1.03 D,"Extra Work", and Section 9-1.03,"Force Account Payment" of the Standard
Specifications.
This method of determining the price of work shall not apply to the performance of any work which is required or
reasonably implied to be performed or furnished under this contract.
10-09. Compensation to the City for Extension of Time. In case the work called for under this contract is not
completed within the time limit stipulated herein, the City shall have the right as provided hereinabove, to extend
the time of completion thereof. If the time limit be so extended, the City shall have the right to charge to the
Contractor and to deduct from the final payment for the work the actual cost to the City of engineering, inspection,
superintendence and other overhead expenses which are directly chargeable to the contract and which accrue
during the period of such extension, except that the cost of final unavoidable delays shall not be included in such
charges.
10-10. Liquidated Damages for Delay. It is agreed by the parties to the contract that time is of the essence
and that, in case all the work is not completed before or upon the expiration of the time limit as set forth, damage,
other than those cost items identified in section 10-09, will be sustained by the City and that it is and will be
impracticable to determine the actual amount of damage by reason of such delay; and it is therefore agreed that
the Contractor will pay to the City the sum of five hundred dollars ($500.00) per day for each and every calendar
day's delay beyond the time prescribed.
SECTION 11. MISCELLANEOUS
11-01. Notice. Whenever any provision of the contract documents requires the giving of written notice, it shall be

cm) wide trench with approximately 12" (30 cm) of blanket extended beyond the up-
slope portion of the trench. Anchor the blanket with a row of staples/stakes
approximately 12" (30 cm) apart in the bottom of the trench. Backfill and compact
the trench after stapling. Apply seed to compacted soil and fold remaining 12"" (30
cm) portion of blanket back over seed and compacted soil. Secure blanket over
compacted soil with a row of staples/stakes spaced approximately 12" (30 cm) apart
across the width of the blanket.

f. Refer to manufacturers' staple guide for correct staple pattern.
• Note: In loose soil conditions, the use of staple or stake lengths greater than 6" (15cm) may be
necessary to properly secure the blankets.
• The contractor shall maintain the blanket until all work on the contract has been completed and
accepted. Maintenance shall consist of the repair of areas where damaged by any cause. All

and the requirements of the City.
Article III. Labor Discrimination.
Attention is directed to Section 1735 of the Labor Code, which reads as follows:
"No discrimination shall be made in the employment of persons upon public works because of the race,
color, national origin or ancestry, or religion of such persons and every contractor for public works
violating this section is subject to all the penalties imposed for a violation of this chapter."
In connection with the performance of work under this contract, the Contractor agrees as follows:
(a) The Contractor will not willfully discriminate against any employee or an applicant for employment
because of race, color, religion, ancestry, or national origin. The Contractor will take affirmative
action to ensure that applicants are employed and that employees are treated during employment
without regard to their race, color, religion, ancestry, or national origin. Such action shall include, but
not be limited to, the following: employment, upgrading, demotion or transfer; recruitment or
recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and
selection for training, including apprenticeship. The Contractor agrees to post in conspicuous
places, available to employees and applicants for employment, notices to be provided by the
awarding authority setting forth the provisions of this Fair Employment Practice section.
(b) The Contractor will send to each labor union or representative of workers with which he or she has
a collective bargaining agreement or other contract or understanding, a notice, to be provided by the
awarding authority, advising the said labor union or worker's representative of the Contractor's
commitments under this section, to employees and applicants for employment.
(c) The Contractor will permit access to his or her records of employment, employment advertisements,
application forms and other pertinent data and records by the Fair Employment Practices
Commission, City of Ukiah or any other appropriate agency of the State of California designated by
the awarding authority, for the purposes of investigation to ascertain compliance with the Fair
Employment Practices section of this contract.
i) (d) A finding of willful violation of the Fair Employment Practices section of this Contract or of the Fair
Employment Practices Act shall be regarded by the awarding authority as a basis for determining
the Contractor to be not a "responsible bidder" as to future contracts for which such Contractor may
submit bids; for revoking the Contractor's pre-qualification rating, if any and for refusing to establish,
reestablish or renew a pre-qualification rating for the Contractor.
The City of Ukiah shall deem a finding of willful receipt of written notice from the Fair Employment
Practices Act to have occurred upon that it has investigated and determined that the Contractor has
violated the Fair Employment Practices Act and has issued an order under Labor Code Section
1426 or obtained an injunction under Labor Code Section 1429.
I Ukiah Skate Park 87 Spec. No. 10-02
Upon receipt of such written notice from the Fair Employment Practices Commission, the City shall
notify the Contractor that unless he or she demonstrates to the satisfaction of the awarding authority
within a stated period that the violation has been corrected, his or her pre-qualification rating will be
revoked at the expiration of such period.
(e) The Contractor agrees that should the City determine that the Contractor has not complied with the
Fair Employment Practices section of this Contract, then pursuant to Labor Code Section 1735 and
1775 the Contractor shall, as a penalty to the City, forfeit for each calendar day or portion thereof,
for each person who was denied employment as a result of such non-compliance, the penalties
provided in the Labor Code for violation of prevailing wage rates. Such monies may be recovered
from the Contractor. The City may deduct any such damages from any monies due the Contractor.
(f) Nothing contained in this Fair Employment Practices section shall be construed in any manner of
fashion so as to prevent the City or the State of California from pursuing any other remedies that
may be available at law.
(g) Prior to awarding the Contract, the Contractor shall certify to the awarding authority that he or she
has or will meet the following standards for affirmative compliance, which shall be evaluated in each
case by the awarding authority:
(1) The Contractor shall provide evidence, as required by the City that he or she has notified all
supervisors, foremen and other personnel officers in writing of the content of the anti-discrimination
clause and their responsibilities under it.
(2) The Contractor shall provide evidence, as required by the City, that he or she has notified all
sources of employees' referrals (including unions, employment agencies, advertisements,
Department of Employment) of the content of the anti-discrimination clause.
(3) The Contractor shall file a basic compliance report, as required by the City. Willfully false
statements made in such reports shall be punishable as provided by law. The compliance report
shall also spell out the sources of the work force and who has the responsibility for determining
whom to hire, or whether or not to hire.
(4) Personally, or through his or her representatives, the Contractor shall, through negotiations with
the unions with whom he or she has agreements, attempt to develop an agreement which will:
a. Spell out responsibilities for nondiscrimination in hiring, referral, upgrading and training
b. Otherwise implement an affirmative anti-discrimination program in terms of the unions'
specific areas of skill and geography to the end that qualified minority workers will be available
and given and equal opportunity for employment.
(5) The Contractor shall notify the City of opposition to the anti-discrimination clause by individuals,
firms or organizations during the period of its pre-qualification.
(h) The Contractor will include the provisions of the foregoing paragraphs 1 through 5 in everyfirst tier
subcontract so that such provisions will be binding upon each such subcontractor.
(i) The "Fair Employment Practices Certification" must be completed and signed prior to the time of i
submitting the bid.
