of the work by any act or neglect of the OWNER or of his
employees, or by any other Contractor employed by the OWNER,
or by changes ordered in the work, or by strikes, lockouts,
fire, unusual delay in transportation, unavoidable casualties
or any causes beyond the CONTRACTOR'S control, or by delay
authorized by the Engineer pending arbitration, or by any
cause which the Engineer shall decide to justify the delay,
then the time of completion shall be extended for such

The waiving of any one or more of the covenants of this
Contract on the part of any party thereto shall be limited to
that particular instance, and shall not be deemed a waiver of
any other breaches or covenants at any time.
In the event any part of this Contract is found to be
unenforceable for any reason, all other parts of this
Contract shall remain in full force and effect.
This Contract shall be binding upon the heirs,
representatives, successors, or assigns of the parties
hereto.

shall not be construed to imply an acceptance of the same should
inferiority become evident at any time prior to the final
acceptance of the work by the Owner, or within the time limit of
one year as set out in the Detail Specifications.
The Engineer does not guarantee the performance of the
Contract by the Contractor, nor shall his inspection be construed
as supervision of actual construction, nor make him responsible
for providing a safe place for the performance of the work by the
Contractor, or the Contractor's employees, or those of the
suppliers, his Subcontractors, nor for access, visits, use, work,
travel or occupance by any person, as these responsibilities are
covered under the provisions of this Contract, the Contractor's
insurance and Performance Bond, and are not the responsibility of
the Engineer. Where the provisions of safety, in any of its
categories, are not being observed, and this condition comes to
the attention of the Engineer or his representative, the Engineer
may require standard safety procedure to be initiated, but the
requirement of these procedures does not constitute a guarantee by
the Engineer as to their adequacy or the safety of the public.
Where plants, buildings, or mass movement of earth is being
undertaken, the Engineer will set such control lines and basic
elevations as are required for the Contractor to make such unit or
plant layouts as are required. When work is undertaken which
requires a constant or generally intermittent checking of lines
and elevations, the Contractor shall maintain such equipment and
personnel as are essential to the actual prosecution of the work.
In these instances, the final grades, alignment and dimensions are
subject to the checking of the Engineer.
15. Reports, Records, and Data
The Contractor shall submit to the Owner such schedule of
quantities and costs, progress schedules, payrolls, reports,
estimates, records and other data as the Owner may request
concerning work performed or to be performed under this Contract.
16. Superintendence by Contractor
At the site of the work the Contractor shall employ a
construction superintendent or foreman who shall have full
authority to act for the Contractor. It is understood that such
representative shall be acceptable to the Engineer and shall be
one who can be continued in that capacity for the particular job
involved unless he ceases to be on the Contractor's payroll.
17. Changes in Work
No changes in the work covered by the approved Contract
Documents shall be made without having prior written approval of
the Owner. Charges or credits for the work covered by the
approved change shall be determined by one or more, or a
combination of the following methods:
(a) Unit bid prices previously approved.
(b) An agreed lump sum.
(c) The actual cost of:
1. Labor, including foremen;
2. Materials entering permanently into the work;
3. The ownership or rental cost of construction plant
and equipment during the time of use of the extra
work;
4. Power and consumable supplies for the operation of
power equipment;
5. Insurance;
6. Social Security and old age and unemployment
contributions.
To the cost under (c) there shall be added a fixed fee to be
agreed upon but not to exceed fifteen percent (15%) of the actual
cost of the work. The fee shall be compensation to cover the cost
of supervision, overhead, bond, profit and any other general
expenses.
18. Extras
Without invalidating the Contract, the Owner may order extra
work or make changes by altering, adding to or deducting from the
work, the Contract sum being adjusted accordingly, and the consent
of the Surety being first obtained where necessary or desirable.
All the work of the kind bid upon shall be paid for at the price
stipulated in the proposal, and no claims for any extra work or
materials shall be allowed unless the work is ordered in writing
by the Owner or its Engineer, acting officially for the Owner, and
the price is stated in such order.
19. Time for Completion and Liquidated Damages
It is hereby understood and mutually agreed, by and between
the Contractor and the Owner, that the date of beginning and the
time for completion as specified in the Contract of the work to be
done hereunder are ESSENTIAL CONDITIONS of this Contract; and it
is further mutually understood and agreed that the work embraced
in this Contract shall be commenced on a date to be specified in
the "Notice to Proceed."
The Contractor agrees that said work shall be prosecuted
regularly, diligently, and uninterruptedly at such rate of
progress as will insure full completion thereof within the time
specified. It is expressly understood and agreed, by and between
the Contractor and the Owner, that the time for the completion of
the work described herein is a reasonable time of the completion
of the same, taking into consideration the average climatic range
and usual industrial conditions prevailing in this locality.
If the said Contractor shall neglect, fail or refuse to
complete the work within the time herein specified, or any proper
extension thereof granted by the Owner, then the Contractor does
hereby agree, as a part consideration for the awarding of this
Contract, to pay to the Owner the amount specified in the
Contract, not as a penalty but as liquidated damages for such
breach of Contract as hereinafter set forth, for each and every
calendar day that the Contractor shall be in default after the
time stipulated in the Contract for completing the work.
The said amount is fixed and agreed upon by and between the
Contractor and the Owner because of the impracticability and
extreme difficulty of fixing and ascertaining the actual damages
the Owner would in such event sustain, and said amount is agreed
to be the amount of damages which the Owner would sustain and said
amount shall be retained from time to time by the Owner from
current periodical estimates.
It is further agreed that time is of the essence of each and
every portion of this Contract and of the Specifications wherein a
definite and certain length of time is fixed for the performance
of any act whatsoever; and where under the Contract an additional
time is allowed for the completion of any work, the new time limit
fixed by such extension shall be of the essence of this Contract.
Provided, that the Contractor shall not be charged with liquidated
damages or any excess cost when the Owner determines that the
Contractor is without fault and the Contractor's reasons for the
time extension are acceptable to the Owner; Provided further, that
the Contractor shall not be charged with liquidated damages or any
excess cost when the delay in completion of the work is due:
(a) To any preference, priority or allocation order duly
issued by the Government;
(b) To unforeseeable cause beyond the control and without the
fault or negligence of the Contractor, including, but not
restricted to, acts of God, or of the public enemy, acts
of the Owner, acts of another Contractor in the
performance of a Contract with the Owner, fires, floods,
epidemics, quarantine restrictions, strikes, freight
embargoes, and severe weather; and
(c) To any delays of Subcontractors or suppliers occasioned
by any of the causes specified in subsections (a) and (b)
of this article:
Provided further, that the Contractor shall, within ten (10)
days from the beginning of such delay, unless the Owner shall
grant a further period of time prior to the date of final
settlement of the Contract, notify the Owner, in writing, of the
causes of the delay, who shall ascertain the facts and extent of
the delay and notify the Contractor within a reasonable time of
its decision in the matter.
20. Correction of Work
All work, all materials, whether incorporated in the work or
not, all processes of manufacture, and all methods of construction
shall be at all times and places subject to the inspection of the
Engineer who shall be the final judge of the quality and
suitability of the work, materials, processes of manufacture, and
methods of construction for the purposes for which they are used.
Should they fail to meet his approval they shall be forthwith
reconstructed, made good, replaced and/or corrected, as the case
may be, by the Contractor at his own expense. Rejected material
shall immediately be removed from the site. If, in the opinion of
the Engineer, it is undesirable to replace any defective or
damaged materials or to reconstruct or correct any portion of the
work injured or not performed in accordance with the Contract
Documents, the compensation to be paid to the Contractor hereunder
shall be reduced by such amount as in the judgment of the Engineer
shall be equitable.
21. Subsurface Conditions Found Different
Should the Contractor encounter subsurface and/or latent
conditions at the site materially differing from those shown on
the Plans or indicated in the Specifications, he shall immediately
give notice to the Engineer of such conditions before they are
disturbed. The Engineer will thereupon promptly investigate the
conditions, and if he finds that they materially differ from those
shown on the Plans or indicated in the Specifications, he will at
once make such changes in the Plans and/or Specifications as he
may find necessary, any increase or decrease of cost resulting
from such changes to be adjusted in the manner provided in
Paragraph 17 of the General Conditions.
22. Claims for Extra Cost
No claim for extra work or cost shall be allowed unless the
same was done in pursuance of a written order of the Engineer
approved by the Owner, as aforesaid, and the claim presented with
the first estimate after the changed or extra work is done. When
work is performed under the terms of subparagraph 17(c) of the
General Conditions, the Contractor shall furnish satisfactory
bills, payrolls and vouchers covering all items of cost and when
requested by the Owner, give the Owner access to accounts relating
thereto.
23. Right of the Owner to Terminate Contract
In the event that any of the provisions of this Contract are
violated by the Contractor, or by any of his Subcontractors, the
Owner may serve written notice upon the Contractor and the Surety
of its intention to terminate the Contract, such notices to
contain the reasons for such intention to terminate the Contract,
and unless within ten (10) days after the service of such notice
upon the Contractor, such violation or delay shall cease and
satisfactory arrangement of correction be made, the Contract
shall, upon the expiration of said ten (10) days cease and
terminate. In the event of any such termination, the Owner shall
immediately serve notice thereof upon the Surety and the
Contractor and the Surety shall have the right to take over and
perform the Contract; Provided, however, that if the Surety does
not commence performance thereof within ten (10) days from the
date of the mailing to such Surety of notice of termination, the
Owner may take over the work and prosecute the same to completion
by Contract or by force account for the account and at the expense
of the Contractor and the Contractor and his Surety shall be
liable to the Owner for any excess cost occasioned the Owner
thereby, and in such event the Owner may take possession of and
utilize in completing the work, such materials, appliances, and
plant as may be on the site of the work and necessary therefor.
24. Construction Schedule and Periodic Estimates
Immediately after execution and delivery of the Contract, and
before the first partial payment is made, the Contractor shall
deliver to the Owner an estimated construction progress schedule
in form satisfactory to the Owner, showing the proposed dates of
commencement and completion of each of the various subdivisions of
work required under the Contract Documents and the anticipated
amount of each monthly payment that will become due the Contractor
in accordance with the progress schedule.
25. Payments to Contractor
(a) Not later than the 10th day of each calendar month the
Owner shall make a progress payment to the Contractor on
the basis of a duly certified and approved estimate of
the work performed during the preceding calendar month
under this Contract, but to insure the proper performance
of this Contract: Provided, that the Contractor shall
submit his estimate not later than the first day of the
month.
(b) In preparing estimates the material delivered on the site
and preparatory work done may be taken into consideration.
(c) All material and work covered by partial payments made
shall thereupon become the sole property of the Owner,
but this provision shall not be construed as relieving
the Contractor from the sole responsibility for the care
and protection of materials and work upon which payments
have been made or the restoration of any damaged work, or
as a waiver of the right of the Owner to require the
fulfillment of all of the terms of the Contract.
(d) Owner's Right to Withhold Certain Amounts and Make
Application Thereof: The Contractor agrees that he will
indemnify and save the Owner harmless from all claims
growing out of the lawful demands of Subcontractor,
laborers, workmen, mechanics, materialmen, and furnishers
of machinery and parts thereof, equipment, power tools,
and all supplies, including commissary, incurred in the
furtherance of the performance of this Contract. The
Contractor shall, at the Owner's request, furnish
satisfactory evidence that all obligations of the nature
hereinabove designated have been paid, discharged, or
waived. If the Contractor fails so to do, then the Owner
may, after having served written notice on the said
Contractor, either pay unpaid bills, of which the Owner
has written notice, direct, or withhold from the
Contractor's unpaid compensation a sum of money deemed
reasonably sufficient to pay any and all such lawful
claims until satisfactory evidence is furnished that all
liabilities have been fully discharged whereupon payment
to the Contractor shall be resumed, in accordance with
the terms of this Contract, but in no event shall the
provisions of this sentence be construed to impose any
obligations upon the Owner to either the Contractor or
his Surety. In paying any unpaid bills of the
Contractor, the Owner shall be deemed the agent of the
Contractor, and any payment so made by the Owner shall be
considered as a payment made under the Contract by the
Owner to the Contractor and the Owner shall not be liable
to the Contractor for any such payments made in good
faith.
26. Acceptance of Project and Final Payment
Upon acceptance of the project by the Owner and the Engineer,
final payment shall be made to the Contractor. The final payment
shall include all money retained, if any. The issuing of the
final payment by the Owner, and the acceptance of the final
payment by the Contractor, shall not, however, operate to release
the Contractor or his Sureties from any obligations under this
Contract or the Performance and Payment Bond.
27. Payments by Contractor
The Contractor shall pay (a) for all transportation and
utility services no later than the 20th day of the calendar month
following that in which services are rendered, (b) for all
materials, tools, and other expendable equipment to the extent of
ninety percent (90%) of the cost thereof, no later than the 20th
day of the calendar month following that in which such materials,
tools, and equipment are delivered at the site of the project and
the balance of the cost thereof, no later than the 30th day
following the completion of that part of the work in or on which
such materials, tools, and equipment are incorporated or, used, and
work in or on which such materials, tools, and equipment are
incorporated or used, and (c) to each of his Subcontractors, no
later than the 5th day following each payment to the Contractor on
account of the work performed by his Subcontractors to the extent
of each Subcontractor's interest therein.
28. Insurance
The Contractor shall not commence work under this Contract
until he has obtained all the insurance required under this
paragraph and such insurance has been approved by the Owner, nor
shall the Contractor allow any Subcontractor to commence work on
his subcontract until the insurance required for the Subcontractor
has been so obtained and approved.
(a) Compensation Insurance: The Contractor shall procure and
shall maintain during the life of this Contract Workmen's
Compensation Insurance as required by applicable State or
territorial law for all of his employees to be engaged in

require the Subcontractor similarly to provide Workmen's
Compensation Insurance. In case any class of employees
engaged in hazardous work on the project under this
Contract is not protected under the Workmen's
Compensation Statute, the Contractor shall provide and
shall cause each Subcontractor to provide adequate
employer's liability insurance for the protection of such
of his employees as are not otherwise protected.
(b) Contractor's Public Liability and Property Damage
Insurance and Vehicle Liability Insurance: The
Contractor shall procure and shall maintain during the
life of this Contract Contractor's Public Liability
Insurance, Contractor's Property Damage Insurance and
Vehicle Liability Insurance in the amounts specified in
the Detailed Specifications.
(c) Subcontractor's Public Liability and Property Damage
Insurance and Vehicle Liability Insurance: The
Contractor shall either (1) require each of his
Subcontractors to procure and to maintain during the life
of his subcontract, Subcontractor's Public Liability and
Property Damage Insurance and Vehicle Liability Insurance
of the type and in the amount specified, (2) insure the
activities of his policy, specified in subparagraph (b)
hereof.
(d) Scope of Insurance and Special Hazards: The insurance
required under subparagraphs (b) and (c) hereof shall
provide adequate protection for the Contractor and his
Subcontractors, respectively, against damage claims which
may arise from operations under this Contract, whether
such operations be by the insured or by anyone directly
or indirectly employed by him and, also against any of
the special hazards which may be encountered in the
performance of this Contract.
(e) Proof of Carriage of Insurance: The Contractor shall
furnish the Owner with certificates showing the type,
amount, class of operations covered, effective dates and
date of expiration of policies. Such certificates shall
also contain substantially the following statement: "The
insurance covered by this certificate will not be
cancelled or materially altered, except after (10) days
written notice has been received by the Owner."
29. Contract Security

at least equal to one hundred percent (100%) of the Contract
prices as security for the faithful performance of this Contract
and also a Payment Bond in an amount not less than one hundred
percent (100%) of the Contract price or in a penal sum not less
than that prescribed by State, territorial or local law, as
security for the payment of all persons performing labor on the
project under this Contract and furnishing materials in connection
with this Contract. The Performance Bond and the Payment Bond may
be in one or in separate instruments in accordance with local
laws.
30. Additional or Substitute Bond
If at any time the Owner for justifiable cause shall be or
become dissatisfied with any Surety or Sureties, then upon the
Performance or Payment Bonds, the Contractor shall within five (5)
days after notice from the Owner so to do, substitute an
acceptable bond (or bonds). in such form and sum and signed by such
other Surety or Sureties as may be satisfactory to the Owner. The
premiums on such bond shall be paid by the Contractor. No further
payments shall be deemed due nor shall be made until the new
Surety or Sureties shall have furnished such an acceptable bond to
the Owner.
31. Assignments
The Contractor shall not assign the whole or any part of this
Contract or any moneys due or to become due hereunder without
written consent of the Owner. In case the Contractor assigns all
or any part of any moneys due or to become due under this
Contract, the instrument of assignment shall contain a clause
substantially to the effect that it is agreed that the right of
the assignee in and to any moneys due or to become due to the
Contract shall be subject to prior claims of all persons, firms
and corporations of services rendered or materials supplied for
the performance of the work called for in this Contract.
32. Mutual Responsibility of Contractors
If, through acts of neglect on the part of the Contractor,
any other Contractor or any Subcontractor shall suffer loss or
damage on the work, the Contractor agrees to settle with such
other Contractor or Subcontractor by agreement or arbitration if
such other Contractor or Subcontractor will so settle. If such
other Contractor or Subcontractors shall assert any claim against
the Owner on account of any damage alleged to have been sustained,
the Owner shall notify the Contractor, who shall indemnify and
save harmless the Owner against any such claim.
33. Separate Contract
The Contractor shall coordinate his operations with those of
other Contractors. Cooperation will be required in the
arrangement for the storage of materials and in the detailed
execution of the work. The Contractor, including his
Subcontractors, shall keep informed of the progress and the detail
work of other Contractors and shall notify the Engineer
immediately of lack of progress or defective workmanship on the
part of other Contractors. Failure of a Contractor to keep
informed of the work progressing on the site and failure to give
notice of lack of progress or defective workmanship by others
shall be construed as acceptance by him of the status of the work
as being satisfactory for proper coordination with his own work.
34. Subcontracting
(a) The Contractor may utilize the services of specialty
Subcontractors on those parts of the work which, under
normal contracting practices, are performed by specialty
Subcontractors.
(b) The Contractor shall not award any work to any Sub-
contractor without prior written approval of the Owner,
which approval will not be given until the Contractor
submits to the Owner a written statement concerning the
proposed award to the Subcontractor, which statement
shall contain such information as the Owner may require.
(c) The Contractor shall be as fully responsible to the Owner
for the acts and omissions of his Subcontractors, and of
persons either directly or indirectly employed by them,
as he is for the acts and omissions of persons directly
employed by him.
(d) The Contractor shall cause appropriate provisions to be
inserted in all subcontracts relative to the work to bind
Subcontractors to the Contractor by the terms of the
General Conditions and other Contract Documents insofar
as applicable to the work of Subcontractors and to give
the Contractor the same power as regards terminating any
subcontract that the Owner may exercise over the
Contractor under any provision of the Contract Documents.
(e) Nothing contained in this Contract shall create any
contractual relation between any Subcontractor and the
Owner.
35. Engineer's Authority
The Engineer shall give all orders and directions
contemplated under this Contract and Specifications, relative to
the execution of the work. The Engineer shall determine the
amount, quality, acceptability, and fitness of the several kinds
of work and materials which are to be paid for under this Contract
and shall decide all questions which may arise in relation to said
work and the construction thereof. The Engineer's estimates and
decisions shall be final and conclusive, except as herein
otherwise expressly provided. In case any questions shall arise
between the parties hereto relative to said Contract or
Specifications, the determination or decision of the Engineer
shall be a condition precedent to the right of the Contractor to
receive any money or payment for work under this Contract affected
in any manner or to any extent by such question.
The Engineer shall decide the meaning and intent of any
portion of the Specifications and of any Plans or drawings where
the same may be found obscure or be in dispute. Any differences
or conflicts in regard to their work which may arise between the
Contractor under this Contract and other Contractors performing
work for the Owner shall be adjusted and determined by the
Engineer.

work of any other Contractors;
(c) to place upon the work or any part thereof only such
loads as are consistent with the safety of that portion
of the work;
(d) to clean up frequently all refuse, rubbish, scrap
materials, and debris caused by his operations, to the
end that at all times the site of the work shall present
a neat, orderly and workmanlike appearance;
(e) before final payment to remove all surplus material,
false -work, temporary structures, including foundations
thereof, plant of any description and debris of every
nature resulting from his operations, and to put the site
in a neat, orderly condition.
(f) to effect all cutting, fitting or patching of his work
required to make the same to conform to the Plans and
Specifications and, except with the consent of the
Engineer, not to cut or otherwise alter the work of any
other Contractor.
37. Quantities of Estimate
Wherever the estimated quantities of work to be done and
materials to be furnished under this Contract are shown in any of
the Documents including the Proposal, they are given for use in
comparing bids and the right is especially reserved except as
herein otherwise specifically limited, to increase or diminish
them as may be deemed reasonably necessary or desirable by the
Owner to complete the work contemplated by this Contract, and such
increase or diminution shall in no way violate this Contract, nor
shall any such increase or diminution give cause for claims or
liability for damages.
38. Lands and Rights -of -Way
Prior to the state of construction, the Owner shall obtain
all lands and rights-of-way necessary for the carrying out and
completion of work to be performed under this Contract.
39. General Guaranty
Neither the final certificate of payment nor any provision in
the Contract Documents, nor partial or entire occupancy of the
premises by the Owner, shall constitute an acceptance of work not
done in accordance with the Contract Documents or relieve the
Contractor of liability in respect to any express warranties or
responsibility for faulty materials or workmanship. The
Contractor shall remedy any defects in the work and pay for any
damage to other work resulting therefrom, which shall appear
within a period of one year from the date of final acceptance of
the work unless a longer period is specified. The Owner will give
notice of observed defects with reasonable promptness.
40. Conflicting Conditions
Any provisions in any of the Contract Documents which may be
in conflict or inconsistent with any of the paragraphs in these
General Conditions shall be void to the extent of such conflict or
inconsistency.
41. Notice and Service Thereof
Any notice to any Contractor from the Owner relative to any
part of this Contract shall be in writing and considered delivered
and the service thereof completed, when said notice is posted, by
certified or registered mail, to the said Contractor at his last
given address, or delivered in person to the said Contractor or
his authorized representative on the work.
42. Provisions Required by Law Deemed Inserted
Each and every provision of law and clause required by law to
be inserted in this Contract shall be deemed to be inserted herein
and the Contract shall be read and enforced as though it were
included herein, and if through mistake or otherwise any such
provision is not inserted, or is not correctly inserted, then upon
the application of either party the Contract shall forthwith be
physically amended to make such insertion or correction.
43. Other Prohibited Interests
No official of the Owner who is authorized in such capacity
and on behalf of the Owner to negotiate, make, accept or approve,
or to take part in negotiating, making, accepting, or approving
any engineering, inspection, construction or material supply
contract or any subcontract in connection with the construction of
the project, shall become directly or indirectly interested
personally in this Contract or in any part hereof. No officer,
employee, attorney, engineer or inspector of or for the Owner who
is authorized in such capacity and on behalf of the Owner to
exercise any legislative, executive, supervisory or other similar
functions in connection with the construction of the project,
shall become directly or indirectly interested personally in this
Contract or in any part thereof, any material supply contract,
subcontract, insurance contract, or any other contract pertaining
to the project.
44. Suspension of Work
Should the Owner be prevented or enjoined from proceeding
with work either before or after the start of construction by
reason of any litigation or other reason beyond the control of the
Owner, the Contractor shall not be entitled to make or assert
claim for damage by reason of said delay; but time for completion
of the work will be extended to such reasonable time as the Owner
may determine will compensate for time lost by such delay with
such determination to be set forth in writing.
45. Figured Dimensions
Figured dimensions, when given in the Plans, shall be
accurately followed, even though they differ from scaled
measurements. No work shown on the Plans, the dimensions of which
are not figured, shall be executed until instructions have been
obtained from the Engineers as to the dimensions to be used.
Large scale and full size drawings shall be followed in preference
to small scale drawings.
46. Diverting and Blocking Traffic
The Contractor may close city streets to traffic as may be
necessary for the expeditious handling of the work, but only where
traffic may be conveniently routed over other open streets and
public ways; provided, however, that no street or public way shall
be closed to traffic for a longer period of time that is necessary
for the construction of the work involved and then only upon the
approval of the Engineer and the City. Proper signs shall be
erected to facilitate the flow of traffic over the detour route.
When excavation work is carried on in the state highway
right-of-way, the Contractor shall make provision for handling and
re-routing traffic as required by the State Highway Department.
47. Danger Signals and Safety Devices
The Contractor shall take all necessary precautions to guard
against damages to property and injury to persons. He shall put
up and maintain in good condition sufficient red or warning lights
at night, suitable barricades and other devices necessary to
protect the public. In case the Contractor fails or neglects to
take such precautions, the Owner may have such lights and
barricades installed and charge the cost of this work to the
Contractor. Such action by the Owner does not relieve the
Contractor of any liability incurred under these Specifications or
Contract.
48. Privileges of Contractors in Streets
The Contractor will be entitled to use such streets, alleys,
roadways, or parts of the streets and alleys as are necessary for
the prosecution of the work. The use of such public thoroughfares
shall be at the direction of the Engineer and in accordance with
provisions as expressed by him.
The Contractor shall maintain at least one lane of open
traffic at all times. Adequate signing and flagmen shall be
provided to safely maintain flow of traffic during construction.
49. Waterways
Present natural and artificial waterways shall be left open
to flow freely. Temporary dams or by-passes may be provided when
found necessary or ordered by the Engineer.
50. Location of Facilities
The locations of any proposed pipe lines, valves, curb
inlets, crossings, etc., as shown on the drawings are for general
information only unless otherwise marked on the drawing. The
exact location of each shall be designated by the Engineer at the
time work is started, after giving due consideration to the local
conditions. The Engineer shall set stakes accordingly, and the
Contractor shall install the work at the designated locations.
51. Work Done Without Lines or Grade
Any work done without lines, grades or levels being given by
the Engineer, or done without the supervision of any inspector or
other representative of the Engineer, may be ordered removed and
replaced at the Contractor's cost and expense.

DETAILED SPECIFICATIONS
FOR
IMPROVEMENTS @ LAKE FAYETTEVILLE SOFTBALL FIELD
Fayetteville, Arkansas
I. SCOPE OF WORK. The work to be done under this Contract,
as shown on the Plans and as provided for in these Spec-
ificati.ons, shall include the furnishing of all necessary
materials, tools, equipment and supplies and performing
all the necessary labor for a complete installation as
set forth herein.
2. EARTHWORK AND GRADING. The work on this project is being
performed in order to improve existing parking and drive
areas, provide additional parking, and to make drainage
improvements for the softball fields. No specific grades
have been planned. It is the intent that grading will be
performed such that the volume of earthwork will be min-
imized while providing a finished project which is struc-
turally sound, properly graded and drained, and blends in
to the surrounding terrain.
A large portion of the planned parking and drive improve-
ments has existing SB-2 base. Topsoil shall be stripped
from those areas without base and additional excavation
performed such as to provide a properly graded surface
and allow for a 6 inch thickness of SB-2 base. Areas to
receive new base shall be thoroughly and properly com-
pacted prior to placement of the base.
It is planned to extend the existing culvert at the
southwest corner of the playground and grade this area.
Excavation from the parking area may be used to backfill
and grade. Any excess excavation may be wasted on site.
All new construction shall be properly backfilled and
graded. Resulting slopes shall be 3:1 or flatter, all
areas have positive drainage and finish dirt grade be
flush with the new asphalt or concrete construction.
3. UNDERCUT. All earthwork shall be performed as described
in Number 2 above. Any unstable areas of subgrade shall
be aerated, manipulated and worked as normally associated
with earthwork operations. If this work will not stabil-
ize the subgrade, undercut may be performed as directed
by the Engineer. Payment will be made for undercut au-
thorized by the Engineer. Measurement for payment shall
be by the Engineer and shall be the volume of earth re-
moved below established subgrade elevation within the
width and depth as established by the Engineer. The unit
price bid for undercut shall be full payment for excava-
tion of authorized unstable material and replacement with
suitable material placed in properly compacted 8" lifts.
Replacement material shall be approved by the Engineer.
4. SB-2 BASE. The objective of this specification is to
provide a graded parking area as shown on the Plans with
properly prepared subgrade and a paving section of 6"
SB-2, primed, with an asphalt driving surface. Depth
measurements of the existing gravel indicate a depth of
3"-7". The existing gravel base shall be scarified and
graded generally conforming to existing slopes. The
existing base shall then be shifted or moved and addi-
tional base added to obtain the desired 6" thickness.
The resulting mix of existing base and additional base

C 1 1/4" to #4 6.5 2"-4" 5+2 4,200 PSI;
' 4. Forming. Forms shall be mortar tight and of sufficient
rigidity to prevent distortion due to the pressure of the concrete
and other loads incident to the construction operations.
Forms of exposed surfaces shall be made of dressed lumber of
uniform thickness, or other approved materials which will provide
' a smooth surface. All exposed corners shall be chamfered 3/4 inch
unless otherwise shown.
1J
C
I
Metal ties or anchorages within the forms shall be so
constructed as to permit their removal to a depth of at least 1
' 1/2 inches from the face without injury to the concrete.
Forms shall be treated with oil immediately before placing
the concrete. Material which will adhere to or discolor the
concrete shall not be used.
Forms shall remain in place a period of time after placement
' of concrete adequate to insure proper curing of concrete, but in
no case less than 24 hours without approval of the Engineer.
5. Reinforcing Steel. When placed in the work, reinforcing
steel shall be free of dirt, detrimental scale, paint, oil or
other foreign substance. Bar reinforcement shall be cut to the
lengths and bent to the shapes shown on the Plans.
' Steel reinforcement shall be accurately placed in the
positions shown on the Plans and firmly held during the placing
' and setting of the concrete. Bars shall be tied at all
intersections except where spacing is less than 1 foot in each
direction, in which case alternate intersections shall be tied.
Distances from the forms shall be maintained by means of
stays, ties, hangers, or other approved supports. If fabric
reinforcement is shipped in rolls, it shall be straightened into
' flat sheets before being placed.
Splicing of bars, except where shown on the Plans, will not
' be permitted without the approval of the Engineer. Unless
otherwise shown, bars shall be lapped 40 diameters to make the
splice.
P6. Handling and Placing Concrete. No concrete shall be
placed on a frozen or soft subgrade. Sawdust, chips and other
construction debris and extraneous matter shall be removed from
' the interior of forms. Where placement is upon dry earth or
gravel, the surface shall be dampened immediately prior to
placement. The concrete when placed shall be of the consistency
' and workability required for the job.
All concrete shall be placed before it has taken its initial
set. Concrete shall be discharged into the forms complete within'
' 1 1/2 hours after the introduction of mixing water to the cement
and aggregates except that this time may be reduced by the
Engineer in hot weather. When the internal temperature of the
' plastic concrete reaches 85°F, the Contractor shall take the
necessary precautions to insure that the temperature of succeeding
batches does not exceed 90°F.
' when the ambient temperate is above 90°F, the forms,
reinforcing steel and other surfaces which will be in contact with
the concrete shall be cooled by means of a water spray or other
' approved methods.
LI
No concrete shall be placed when the air temperature is below
35°F unless provision is made for heating the ingredients and for
t enclosing the concrete and heating the enclosure. No concrete
shall be placed when the weather forecasts indicate air
temperatures below 32°F during the succeeding 5 days unless
provision is made for enclosing the concrete and heating the
' enclosure, Insulated forms may be used provided they have prior
approval. The concrete shall be enclosed immediately after
placement and the concrete and air in the enclosure kept above
' 50°F for a period of five days.
All concrete, during and immediately after placing, shall be
' thoroughly consolidated by mechanical vibration. The vibration
shall be of sufficient duration and intensity to thoroughly
consolidate the concrete, but shall not be continued so as to
cause segregation. Vibration shall not be continued at any one
point to the extent that localized areas of grout are formed.
Upon removal of forms, any honeycombed areas shall be
' immediately removed or repaired. Loose rock and concrete shall be
removed, the honeycombed area keyed with a chisel or other means,
and a non -shrink grout applied. Should there be any areas which,
in the opinion of the Engineer, are honeycombed to such an extent
' that the structural strength or aesthetic value of the concrete
has been reduced to an unacceptable level, the concrete shall be
removed and replaced. The area to be removed shall be as directed
' by the Engineer and may extend beyond the flawed area in order to
retain structural integrity or a pleasing appearance.
7. Finishing. Concrete surface finishes shall be
'classified as follows:
Class 1. Ordinary Surface Finish
' Class 2. Rubbed Finish
Class 3. Brush Finish
' All concrete shall be given a Class 1, ordinary Surface
Finish and, if further finishing is required, such other type of
finish as is specified.
' Immediately following the removal of forms, a Class 1 finish
shall be obtained. Fins and irregular projections shall be
removed from surfaces. Cavities produced by form ties and all
' other holes, broken corners or edges, and other defects shall be
thoroughly cleaned and carefully pointed and trued with mortar.
The resulting surface shall be true and uniform.
The exposed face(s) of formed concrete (i.e., headwalls,
wingwalls, etc.) shall receive a Class 2, Rubbed Finish. The
rubbing of concrete shall start as soon as conditions will permit
' after the removal of forms. Surfaces to be finished shall be
saturated with water and rubbed with a medium coarse Carborundum
stone, using a small amount of mortar on its face. Rubbing shall
be continued until form marks, projections and irregularities have
LI
I
been removed, voids filled, and a uniform surface has been
obtained. The final finish shall be obtained by rubbing with a
' fine Carborundum stone and water until the entire surface is of a
smooth texture and uniform color.
Unless otherwise specified, the exposed horizontal surface of
' concrete shall receive a Class 3, Brush Finish. After the
concrete has been placed, consolidated, screeded, and laitance
removed, the surface shall be finished by dragging a wire or fiber
' broom across the surface transverse to the centerline of the
surface. The resulting grooves shall be substantially from 1/16
to 3/16 inch in depth.
' 8. Tolerances. Reinforcing steel shall be placed within
1/2 inch of planned spacing and within 1/4 inch of planned
clearance form face of concrete. Unless otherwise specified
concrete shall be placed to within + 1 inch of plan grade.
9. Curing. The concrete shall be cured by covering with
' wet burlap blankets or coating with white pigmented membrane
curing solution. When membrane curing is used the exposed
concrete shall be thoroughly sealed immediately after the free
water has left the surface with a curing solution conforming to
' the requirements of AASHTO M148. When curing with mats or
blankets, the exposed surface shall be covered as soon after
finishing as possible without marring the finish of the concrete.
' 10. Joints. Joints shall be made in structures only as
shown on the Plans. Edges at expansion joints shall be tooled.
' Expansion joints shall be made with a bituminous type
preformed joint filler meeting the requirements of AASHTO M33.
' Contraction joints shall be filled with a cold -poured
synthetic polymer which will form an effective seal against water
and incompressibles. It shall cure sufficiently in three hours so
' that it will not pick up under traffic.
11. Backfilling and Opening to Traffic. Concrete structures
' shall not be backfilled in less than 7 days from completion of
placement unless concrete test cylinders indicate the concrete to
be at design strength. No fill shall be placed over a concrete
structure in less than 14 days from completion of the structure,
and then only if concrete test cylinders indicate the concrete to
be at design strength. Bridges shall not be opened to traffic in
less than 28 days from completion unless otherwise approved by the
' Engineer.
12. Testing. A minimum of one set of concrete test
' cylinders shall be made each day that concrete is placed, further
provided that one set shall be made for each 50 cubic yards, or
increment thereof, placed each day. A set shall consist of a
minimum of 3 cylinders. The cylinders shall be made and tested by
an independent engineering testing laboratory, or the Contractor
I
may make the cylinders in the presence of the Engineer and deliver
the cylinders to the laboratory for testing. One cylinder shall
be tested at 7 days from date of placement. Should the 7 day test
result be less than design strength, a second cylinder shall be
tested at 28 days, or a lesser period if approved by the Engineer.
' Should test specimens indicate that the in -place concrete is
not at design strength 28 days from date of completion, the
Contractor may be required to provide cores of the in -place
' concrete, of the diameter required by the Engineer, for testing.
Should these tests of the in -place concrete indicate a strength
less than design, the Contractor may be required to remove and
' replace the inferior concrete. In order to retain the structural
integrity or, in the case of exposed concrete, to maintain the
aesthetic value of the work, additional concrete may be required
to be removed and replaced.

of concrete.
The Engineer may at any time make, or have made, slump and
air entrainment tests of the concrete being placed. The
Contractor shall cooperate with the Engineer in taking of the
sample and the making of these tests. Any concrete not meeting
the Specifications for the Class of concrete being placed shall be
immediately corrected or removed from the job. The Contractor
shall not be responsible for any costs associated with slump and
air tests.
13. Corrections to Work. The Contractor shall be completely
responsible for providing concrete of the quality specified and
placing the concrete to the lines and grades shown on the Plans
within the tolerances specified. The costs for any and all work
and materials required to being the finished product is not in
compliance with the Plans and Specifications, including the
removal and replacement of concrete, shall be the responsibility
of the Contractor. The Contractor shall not grumble or gripe to
the Engineer and shall maintain a pleasant attitude while making
corrections.
14.
Method of Measurement.
Where work is performed under a
unit price
