water contamination. Run-on water that cannot be diverted shall be treated as construction runoff and adequate
BMPs shall be employed.
The ECS shall evaluate any non-stormwater coming onto the site, such as springs, seeps, and landscape irrigation
return flow. If such flow is identified, BMPs shall be used to protect off-site water from running on-site and
becoming contaminated with sediment or other pollutants.
The ECS shall review existing inlets and culverts to determine if inlet protection is needed due to water flow
patterns. Prior to construction commencing, inlets and culverts needing protection shall be protected and the
location of the implemented BMP added to the SWMP site map.
When additional BMPs are required the Contractor shall implement the additional BMPs and the ECS shall record
and describe them on the SWMP site map. Additional BMPs will be measured and paid for in accordance with
subsections 208.07 and 208.08.
(a) Project Review. The Contractor may submit modifications to the Contract’s erosion control measures in a
written proposal to the Engineer. Such proposed modifications shall be submitted at least ten working days
prior to the beginning of any construction work. The written proposal shall include the following minimum

Contractor’s expense.
(c) Construction Implementation. The Contractor shall incorporate into the project all erosion and
sediment control features as outlined in the accepted schedule.
(d) Stabilization. Permanent stabilization is defined as the covering of disturbed areas with final seed and mulch
as indicated on the plans. When required by the plans, a soil retention blanket shall be used in combination with
the final seed and mulch. Temporary stabilization is defined as the covering of disturbed areas with seed, mulch
with a tackifier, soil roughening, soil binder, or a combination thereof. Other permanent or temporary soil
stabilization techniques may be proposed, in writing, by the Contractor and used upon approval, in writing, by the
Engineer.
During the summer and winter when seeding is not allowed, temporary stabilization shall be placed. Temporary
stabilization will not be paid for the convenience of the Contractor. Temporary stabilization shall consist of:
surface roughening via scarifying surface to 2-4 inches variation of surface or vertical tracking, 1.5 tons of
certified weed free forage hay or straw mulching per acre mechanically crimped into the soil in combination with
an organic mulch tackifier, soil binder, cellulose fiber mulch with tackifier, or a combination thereof as
approved. Surface roughening shall not be used alone.

operations shall not exceed 34 acres: 17 acres for clearing and grubbing plus 17 acres for earthwork operations.
The Contractor shall permanently stabilize each 17 acre increment of the project immediately upon completion of
the grading of that section. Once earthwork has begun on a section, it shall be pursued until completion. If
approved by the Engineer, slopes from the edge of pavement to the point of slope selection may be left unseeded
until paving has been completed but shall be temporarily stabilized as approved by Engineer.
The duration of the exposure of uncompleted construction to the elements shall be as short as practicable.
Completed areas shall be permanently stabilized immediately, but in no case more than 48 hours after completion.
Disturbed areas where work is temporarily halted shall be temporarily stabilized immediately after the activity
ceased. Temporary stabilization shall consist of: surface roughening via scarifying surface to 2-4 inches variation
of surface or vertical tracking, 1.5 tons of certified weed free forage hay or straw mulching per acre, mechanically
crimped into the soil in combination with an organic mulch tackifier, soil binder, cellulose fiber mulch with
tackifier, or a combination thereof as approved. Payment for temporary stabilization will be made at the contract
unit price if the work was interrupted due to no fault or negligence of the Contractor. Payment will not be made
for temporary stabilization required by Contractor’s negligence, by the lack of proper Contractor scheduling or
for the convenience of the Contractor.

REVISION OF SECTIONS 101, 107, AND
208 WATER QUALITY CONTROL
Clearing and grubbing operations shall be scheduled and performed so that grading operations and permanent
stabilization measures can follow immediately thereafter if the project conditions permit. Otherwise temporary
stabilization measures may be required between successive construction stages. No payment will be made for
additional work required because the Contractor has failed to properly coordinate the entire erosion control
schedule, thus causing previously seeded areas to be disturbed by operations that could have been performed
prior to the seeding. Upon failure of the Contractor to coordinate the permanent stabilization measures with the
grading operations in a manner to effectively control erosion and prevent water pollution, the Engineer will
suspend the Contractor’s grading operations and withhold monies due to the Contractor on current estimates
until such time that all aspects of the work are coordinated in an acceptable manner.
(e) Maintenance. All erosion and sediment control practices and other protective measures identified in the
SWMP as BMPs for Stormwater Pollution Prevention shall be maintained in effective operating condition.
BMPs shall be continuously maintained in accordance with good engineering, hydraulic and pollution control
practices, including removal of collected sediment when silt depth is 50 percent or more of the height of the
erosion control device.
Complete site assessment shall be performed as part of comprehensive inspection and maintenance
procedures, to assess the adequacy of BMPs at the site and the necessity of changes to those BMPs to ensure
continued effective performance. Where site assessment results in the determination that new or replacement
BMPs are necessary, the BMPs shall be installed to ensure continuous implementation. When identified,
BMPs shall be added, modified or replaced as soon as possible, immediately in most cases.
Where BMPs have failed, resulting in noncompliance, they shall be repaired or replaced as soon as possible,
immediately in most cases, to minimize the discharge of pollutants.
The Contractor shall update the SWMP Notebook by describing and recording new and replacement BMPs.
New or replacement BMPs will be measured and paid for in accordance with subsections 208.07 and 208.08.
From the time seeding and mulching work begins until the date the project is declared complete, the
Contractor shall keep all seeded areas in good condition at all times. Any damage to seeded areas or to mulch
materials shall be promptly repaired as directed.
If the Contractor fails to maintain the erosion and sediment control features in accordance with the Contract, or
as directed, the Engineer may at the expiration of a period of 48 hours, after having given the Contractor
written notice, proceed to maintain the features as deemed necessary. The cost thereof will be deducted from
any compensation due, or which may become due to the Contractor under this contract.
Temporary erosion and sediment control measures shall remain upon completion of the project unless otherwise
directed by the Engineer. If removed, the area in which these features were constructed shall be returned to a
condition similar to that which existed prior to its disturbance. At the completion of the Contract, removed
salvageable temporary erosion control items shall become the property of the Contractor.

REVISION OF SECTION 104
SCOPE OF WORK
Section 104 of the Standard Specifications is hereby revised for this project as follows:
Subsection 104.02 shall include:
Site Conditions
A. General:
1. The Contractor acknowledges that he has satisfied himself as to the nature and location of the work,
the general and local conditions, particularly those bearing upon access to the site; handling, storage,
and disposal of materials; availability of water, electricity and roads; uncertainties of weather, or
similar physical conditions at the site; the conformation and conditions of the ground; the equipment
and facilities needed preliminary to and during the execution of the work; and all other matters which
can in any way affect the work or the cost thereof under this Contract.
2. The Contractor further acknowledges that he has satisfied himself as to the character, quality and
quantity of surface and subsurface materials to be encountered from his inspection of the site and from
reviewing any available records of exploratory work furnished by the Owner or included in these
Documents. Failure by the Contractor to acquaint himself with the physical conditions of the site and
all the available information will not relieve him from responsibility for properly estimating the
difficulty or cost of successfully performing the work.
3. The Contractor warrants that as a result of his examination and investigation of all the aforesaid data
that he can perform the work in a good and workmanlike manner and to the satisfaction of the Owner.
The Owner assumes no responsibility for any representations made by any of its officers or agents
during or prior to the execution of this Contract, unless (1) such representations are expressly stated in
the Contract, and (2) the Contract expressly provides that the responsibility therefore is assumed by the
Owner.
B. Information on Site Conditions:
Any information obtained by the Engineer regarding site conditions, subsurface information, groundwater
elevations, existing construction of site facilities, and similar data will be available for inspection, as
applicable, at the office of the Engineer upon request. Such information is offered as supplementary
information only. Neither the Engineer nor the Owner assumes any responsibility for the completeness or
interpretation of such supplementary information.
1. Differing Subsurface Conditions:
a. In the event that the subsurface or latent physical conditions are found materially different
from those indicated in these Documents, and differing materially from those ordinarily
encountered and generally recognized as inherent in the character of work covered in these
Contract Documents, the Contractor shall promptly, and before such conditions are disturbed,
notify the Engineer in writing of such changed conditions.

REVISION OF SECTION 104
SCOPE OF WORK
b. The Engineer will investigate such conditions promptly and following this investigation, the
Contractor shall proceed with the work, unless otherwise instructed by the Engineer. If the
Engineer finds that such conditions do so materially differ and cause an increase or decrease in
the cost of or in the time required for performing the work, the Engineer will recommend to
the Owner the amount of adjustment in cost and time he considers reasonable. The Owner
will make the final decision on all Change Orders to the Contract regarding any adjustment in
cost or time for completion.
2. Underground Utilities: Known utilities and structures adjacent to or encountered in the work are
shown on the Drawings. The locations shown are taken from existing records and the best information
available from existing utility plans and potholing. However, it is expected that there may be some
discrepancies and omissions in the locations and quantities of utilities and structures shown. Those
shown are for the convenience of the Contractor only, and no responsibility is assumed by either the
Owner or the Engineer for their accuracy or completeness.
C. Execution:
1. Notify private owners of adjacent properties, utilities, irrigation canals, and affected government
agencies when prosecution of Work may affect them.
2. Where the Contractor's operations could cause damage or inconvenience to railway, telegraph,
telephone, television, oil, gas, electricity, water, sewer, or irrigation systems, the operations shall be
suspended until all arrangements necessary for the protection of these utilities and services have been
made by the Contractor.
3. Notify all utility offices which are affected by the construction operation at least 48 hours in advance.
Under no circumstances expose any utility without first obtaining permission from the appropriate
agency. Once permission has been granted, locate, expose, and provide temporary support for all
existing underground utilities.
4. The Contractor shall protect all utility poles from damage. If interfering power poles, telephone poles,
guy wires, or anchors are encountered, notify the Engineer and the appropriate utility company at least
48 hours in advance of construction operations to permit the necessary arrangements for protection or
relocation of the interfering structure.
5. The Contractor shall be solely and directly responsible to the owner and operators of such properties
for any damage, injury, expense, loss, inconvenience, delay, suits, actions, or claims of any character
brought because of any injuries or damage which may result from the construction operations under
this Contract.
6. Neither the Owner nor its officers or agents shall be responsible to the Contractor for damages as a
result of the Contractor's failure to protect utilities encountered in the work.
7. If the Contractor, while performing the Contract, discovers utility facilities not identified in the
Drawings or Specifications, he shall immediately notify the Owner, utility, and the Engineer in writing.
8. In the event of interruption to domestic water, sewer, storm drain, or other utility services as a result of
accidental breakage due to construction operations, promptly notify the proper authority.

REVISION OF SECTION 104
SCOPE OF WORK
The contractor shall cooperate with said authority in the restoration of service as promptly as possible
and bear all costs of repair.
9. The Contractor shall replace, at his own expense, any and all other existing utilities or structures
removed or damaged during construction, unless otherwise provided for in these Contract Documents
or ordered by the Engineer.
10. Interfering Structures - The Contractor shall take necessary precautions to prevent damage to existing
structures whether on the surface, aboveground, or underground. An attempt has been made to show
major structures on the Drawings. The completeness and accuracy cannot be guaranteed, and it is
presented simply as a guide to avoid known possible difficulties.
11. Field Relocation - During the progress of construction, it is expected that minor relocations of the work
will be necessary. Such relocations shall be made only by direction of the Engineer. If existing
structures are encountered that prevent the construction, and that are not properly shown on the
Drawings, notify the Engineer before continuing with the construction in order that the Engineer may
make such field revision as necessary to avoid conflict with the existing structures. If the Contractor
shall fail to so notify the Engineer when an existing structure is encountered, and shall proceed with
the construction despite the interference, he shall do so at his own risk.
D. Easements: Where portions of the work are located on public or private property, easements and permits will
be obtained by the Owner. Easements will provide for the use of the property for construction purposes to the
extent indicated on the easements. Copies of these easements and permits are available upon request to the
Owner. It shall be the Contractor's responsibility to determine the adequacy of the easement obtained in every
case and to abide by all requirements and provisions of the easement. The Contractor shall confine his
construction operations to within the easement limits or make special arrangements with the property owners
or appropriate public agency for the additional area required. Any damage to property, either inside or outside
the limits of the easements provided by the Owner, shall be the responsibility of the Contractor as specified
herein. The Contractor shall remove, protect, and replace all fences or other items encountered on public or
private property. Before final payment will be authorized by the Engineer, the Contractor will be required to
furnish the Owner with written releases from property owners or public agencies where side agreements or
special easements have been made by the Contractor or where the Contractor's operations, for any reason,
have not been kept within the construction right-of-way obtained by the Owner.
E. Land Monuments: The Contractor shall notify the Engineer of any existing Federal, State, Town, County, and
private land monuments encountered. Private monuments shall be preserved, or replaced by a licensed
surveyor at the Contractor's expense. When Government monuments are encountered, the Contractor shall
notify the Engineer at least two (2) weeks in advance of the proposed construction in order that the Engineer
will have ample opportunity to notify the proper authority and reference these monuments for later
replacement.
Subsection 104.04 shall include:
Any work done by the Contractor without traffic control will not be paid for under the terms of this Contract. The
Contractor will not be paid for traffic control costs incurred during Contractor caused delays.
At or near the end of each work day, a representative of the Contractor, the Traffic Control Supervisor, and the
Owner’s Field Representative shall meet to discuss the progress of the work and the placement of traffic control
devices. Any necessary adjustments shall be made. The Contractor shall also review at this time with the

Section 105 of the Standard Specifications is hereby revised for this project as follows:
Subsection 105.02 shall be replaced with:
Submittals
A. Requirements:
1. Where required by the Specifications, the Contractor shall submit descriptive information that will enable
the Engineer to determine whether the Contractor’s proposed materials, equipment, methods of work are in
general conformance to the design concept and in accordance with the Drawings and Specifications. The
information submitted may consist of drawings, specifications, descriptive data, certificates, samples, test
results, product data, and such other information, all as specifically required in the Specifications. In some
instances, specified submittal information describes some, but not all features of the material, equipment,
or method of work.
2. The Contractor shall be responsible for the accuracy and completeness of the information contained in each
submittal and shall assure that the material, equipment, or method of work shall be as described in the
submittal. The Contractor shall verify that all features of all products conform to the requirements of the
Drawings and Specifications. The Contractor shall ensure that there is no conflict with other submittals
and notify the Engineer in each case where its submittal may affect the work of another Contractor or the
Owner. The Contractor shall ensure coordination of submittals among the related crafts and
subcontractors.
3. Submittals will be reviewed for overall design intent and returned to Contractor with action to be indicated
by the Engineer. It shall be the Contractor’s responsibility to assure that previously accepted documents
are destroyed when they are superseded by a resubmittal as such.
4. It shall be the Contractor’s responsibility to ensure that required items are corrected and resubmitted. Any
work done before approval shall be at the Contractor’s own risk.
B. Submittal Procedure:
1. Unless a different number is called for in the individual sections, four (4) copies of each submittal and
sample are required, two (2) of which will be retained by the Engineer. The Contractor shall receive two
(2) copies in return. Faxed submittals will not be accepted.
2. Submittals that are related to or affect each other shall be forwarded simultaneously as a package to
facilitate coordinated review. Uncoordinated submittals will be rejected.
3. If the items or system proposed are acceptable but the major part of the individual drawings or documents
are incomplete or require revision, the submittal will be returned with requirements for completion.
4. The right is reserved for the Engineer to require submittals in addition to those called for in individual
sections.
5. Submittals regarding material and equipment shall be submitted directly to the Engineer and will be
accompanied by a transmittal form. A separate form shall be used for each specific item, class of material,

REVISION OF SECTION 105
CONTROL OF WORK
equipment, and items specified in separate discrete sections for which the submittal is required. Submittals
for various items shall be made with a single form when the items taken together constitute a
manufacturer’s package or are so functionally related that expediency indicates checking or review of the
group or package as a whole.
6. A unique number, sequentially assigned, shall be noted on the transmittal form accompanying each item
submitted. Original submittal numbers shall have the following format: “XXX-Y;” where “XXX” is the
originally assigned submittal number and “Y” is a sequential letter assigned for resubmittals (i.e., A, B, or
C being the first, second and third resubmittals, respectively). Submittal 25B, for example, is the second
resubmittal of Submittal 25.
7. If the Contractor proposes to provide material, equipment, or method of work that deviates from the
Contract Documents, it shall indicate so under “deviations” on the transmittal form accompanying the
submittal copies.
8. Submittals that do not have all the information required to be submitted, including deviations, are not
acceptable and will be returned without review.
C. Review Procedure:
1. Submittals are specified for those features and characteristics of materials, equipment, and methods of
operation that can be selected based on the Contractor’s judgment of their conformance to the requirements
of the Drawing and Specifications. Other features and characteristics are specified in a manner that
enables the Contractor to determine acceptable options without submittals. The review procedure is based
on the Contractor’s guarantee that all features and characteristics not requiring submittals conform to the
Drawings and Specifications. Review shall not extend to means, methods, techniques, sequences, or
procedures of construction or to verifying quantities, dimensions, weights or gages, or fabrication
processes (except where specifically indicated or required by the Specifications) of separate items, and as
such, will not indicate approval of the assembly in which the item functions.
2. Unless otherwise specified, within twenty-one (21) calendar days after receipt of the submittal, the
Engineer will review the submittal and return copies. The returned submittal will indicate one of the
following actions:
a. If the review indicates that the material, equipment, or work method complies with the Specifications,
submittal copies will be marked “NO EXCEPTIONS TAKEN”. In this event, the Contractor may
begin to implement the work method or incorporate the material or equipment covered by the
submittal.
b. If the review indicates limited corrections are required, copies will be marked “REVIEWED,
COMMENTS AS NOTED”. The Contractor may begin implementing the work method or
incorporating the material and equipment covered by the submittal in accordance with the noted
corrections.
Where submittal information will be incorporated in Operation and Maintenance data, a corrected copy
shall be provided.

c. If the review indicates that the submittal is insufficient or contains incorrect data, copies will be
marked “REVISE AND RESUBMIT”. Except at its own risk, the Contractor shall not undertake work
covered by this submittal until it has been revised, resubmitted and returned marked either “NO
EXCEPTIONS TAKEN” or “REVIEWED, COMMENTS AS NOTED”.
d. If the review indicates that the material, equipment, or work method do not comply with the
Specifications, copies of the submittal will be marked “REJECTED”. Submittals with deviations that
have not been identified clearly may be rejected. Except at its own risk, the Contractor shall not
undertake the work covered by such submittals until a new submittal is made and returned marked
either “NO EXCEPTIONS TAKEN” or “REVIEWED, COMMENTS AS NOTED”.
D. Drawing:
1. The term “shop drawings” includes drawings, diagrams, layouts, schematic, descriptive literature,
illustrations schedules performance and test data, and similar materials furnished by Contractor to explain
in detail specific portions of the work required by the Contract.
2. Contractor shall coordinate all such drawings, and review them for legibility, accuracy, completeness and
compliance with contract requirements and shall indicate this approval thereon as evidence of such
coordination and review. Shop drawing submitted to the Engineer without evidence of Contractor’s
approval will be returned for resubmission.
3. Shop drawing shall be clearly identified with the name and project number of this contract, and references
to applicable specification paragraphs and contract drawings. When catalog pages are submitted,
applicable items shall be clearly identified.
4. Contractor shall stamp his approval on shop drawings prior to submission to the Engineer as indication of
his checking and verification of dimensions and coordination with interrelated items. Stamp shall read:
“(Contractor’s Name) represents that we have determined and verified all field dimensions and
measurements, field construction criteria, materials, catalog numbers and similar data, and that we have
checked with the requirements of the Specifications and Drawings, the Contract Documents, and General
Conditions”.
Marks on drawings by Contractor shall not be in red. Any marks by Contractor shall be duplicated on all
copies submitted.
5. If shop drawings show variations from contract requirements, Contractor shall describe such variations in
writing, separate from the drawings, at time of submission. All such variations must be approved by the
Engineer. If Engineer approves any such variations, he shall issue an appropriate contract modification,
except that, if the variation is minor and does not involve a change in price or in time of performance, a
modification need not be issued.
6. Should the Contractor propose any item on his shop drawings or incorporate an item into the work, and
that item should subsequently prove to be defective or otherwise unsatisfactory, (regardless of the
Engineer’s preliminary review), the Contractor shall, at his own expense, replace the item with another
item that will perform satisfactorily.

D. Owner’s Responsibility
1. Owner’s review is only for the purpose of checking conformity with the Contract Documents and
assisting the Contractor in coordinating the Work with the needs of the Project.
2. It is not to be construed as relieving contractor from any responsibility to determine the
means, methods, techniques, sequences and procedures of construction.
D. Modifications to Time of Completion in the Approved Schedule
The date of beginning and the time for completion of the work are essential conditions of the Contract
Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed.
The Contractor will proceed with the work at such rate of progress to ensure full completion within the
contract time. It is expressly understood and agreed, by and between the Contractor and the Owner that the
contract time for the completion of the work described herein is a reasonable time, taking into consideration
the climatic and other factors prevailing in the locality of the work.
Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown in the
proposal. The "Contract Time" anticipates "Normal" weather and climate conditions in and around the
vicinity of the Project site during the times of year that the construction will be carried out. Extensions of
time based upon weather conditions shall be granted only if the Contractor demonstrates clearly that such
conditions were "unusually severe," would not have been reasonably anticipated, and that such conditions
adversely affected the Contractor’s work and thus required additional time to complete the work.

REVISION OF SECTION 108
PROSECUTION AND PROGRESS
The following specifies the procedure for the determination of time extensions for unusually severe
weather. The listing below defines the anticipated number of calendar days lost to adverse weather for each
month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data for
the geographic location of the project.
Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions
JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
(7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5)
The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion
thereof) weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing
throughout the contract on a monthly basis, actual adverse weather days and the impact of adverse weather
days that delay the work will be recorded on a day-to-day basis. It is assumed that the work will be carried
out Mondays through Fridays (holidays accepted) unless an approved construction schedule or written
authorization from the Owner indicates otherwise. The number of days of delayed work due to adverse
weather or the impact thereof will then be compared to the monthly adverse weather schedule above.
An actual adverse weather day must prevent work for 50 percent or more of the Contractor’s workday, delay
work critical to the timely completion of the project, and be documented by the Contractor. The City
Representative observing the construction shall determine on a daily basis whether or not work can
proceed or if work is delayed due to adverse weather or the effects thereof. The Contractor shall notify the
Engineer in writing of any disagreement as to whether or not work can proceed on a given date, within 2
calendar days of that date. The Owner will use the above written notification in determining the number
of working days for which work was delayed during each month.
At the end of each month, if the number of working days for which work was delayed due to adverse
weather exceeds that shown in the above schedule, a Change Order will be executed which increases the
Contract Time. The number of work days delayed due to adverse weather or the impact thereof will then be
converted to Calendar Days based on the contract completion day and date. This conversion assumes a 5-day
work week, Mondays through Fridays, holidays excepted; should the Contractor have authorization to work
weekends and/or holidays, and then the method of conversion of workdays to calendar days would take
this into consideration. The contract time period will then be increased by the number of calendar days
calculated above and a new contract completion day and date will be set.
The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all weather-
dependent activities.
While extensions of time shall be granted for "unusually severe" weather or climate conditions, the
Owner shall make no monetary compensation for any costs to the Contractor arising out of such
delays. The Contractor shall comply with the portions of the Contract Documents relating to his project
schedule and amendments thereto which result from the "unusually severe" weather condition.
Breakdowns in equipment or lack of performance by the Contractor will not be considered justification for
an extension of time. Liquidated damages will be assessed as delineated elsewhere.

REVISION OF SECTIONS 105 AND 106
CONFORMITY TO THE CONTRACT OF HOT MIX ASPHALT
(LESS THAN 5000 TONS)
Sections 105 and 106 of the Standard Specifications are hereby revised for this project as follows:
Delete subsection 105.05 and replace with the following:
105.05 Conformity to the Contract of Hot Mix Asphalt. Conformity to the Contract of all Hot Mix Asphalt, Item 403,
except Hot Mix Asphalt (Patching) and temporary pavement will be determined by tests and evaluations of elements that
include asphalt content, gradation, in-place density and joint density in accordance with the following:
All work performed and all materials furnished shall conform to the lines, grades, cross sections, dimensions, and material
requirements, including tolerances, shown in the Contract.
For those items of work where working tolerances are not specified, the Contractor shall perform the work in a manner
consistent with reasonable and customary manufacturing and construction practices.
When the Engineer finds the materials or work furnished, work performed, or the finished product are not in conformity with
the Contract and has resulted in an inferior or unsatisfactory product, the work or material shall be removed and replaced or
otherwise corrected at the expense of the Contractor.
Materials will be sampled randomly and tested by the Department in accordance with Section 106 and with the applicable
procedures contained in the Department's Field Materials Manual. The approximate maximum quantity represented by each
sample will be as set forth in Section 106. Additional samples may be selected and tested as set forth in Section 106 at the
Engineer's discretion.
A process will consist of either a single test value or a series of test values resulting from related tests of an element of the
Contractor’s work and materials. An element is a material or workmanship property that can be tested and evaluated for
quality level by the Department approved sampling, testing, and analytical procedures. All materials produced will be
assigned to a process. A change in process is defined as a change that affects the element involved. For any element, with
the exception of the process for joint density element, a process normally will include all produced materials associated with
that element prior to a change in the job mix formula (Form 43). For joint density, a new process will be established for
each new layer of pavement or for changes in joint construction. Density measurements taken within each compaction test
section will be a separate process. The Engineer may separate a process in order to accommodate small quantities or unusual
variations.
Evaluation of materials for pay factors (PF) will be done using only the Department’s acceptance test results. Each process
will have a PF computed in accordance with the requirements of this Section. Test results determined to have sampling or
testing errors will not be used.
Except for in-place density measurements taken within a compaction test section, any test result for an element greater than
the distance 2 x V (see Table 105-2) outside the tolerance limits will be designated as a separate process and the pay factor
will be calculated in accordance with subsection 105.05(a). An element pay factor less than zero shall be zero. The
calculated PF will be used to determine the Incentive/Disincentive Payment (I/DP) for the process.
In the case of in-place density or joint density the Contractor will be allowed to core the exact location (or immediately
adjacent location for joint density) of a test result more than 2 x V outside the tolerance limit. The core must be taken and
furnished to the Engineer within eight hours after notification by the Engineer of the test result. The result of this core will be
used in lieu of the previous test result. Cores not taken within eight hours after notification by the Engineer will not be used
in lieu of the test result. All costs associated with coring will be at the Contractor s expense.
North College Rear Access Road Improvement Project
Project Special Provisions May 2014
96
(a) Representing Small Quantities. When it is necessary to represent a process by only one or two test results, PF will be the
average of PFs resulting from the following:
If the test result is within the tolerance limits then PF = 1.00
If the test result is above the maximum specified limit, then
PF = 1.00 – [0.25(TO
- TU
)/V]
If the test result is below the minimum specified limit, then
PF = 1.00 – [0.25(TL
- TO
)/V]
Where: PF = pay factor.
V = V factor from Table 105-2.
TO
= the individual test result.
TU
= upper specification limit.
TL
= lower specification limit.
The calculated PF will be used to determine the I/DP for the process.
(b) Determining Quality Level. Each process with three or more test results will be evaluated for a quality level (QL) in
accordance with Colorado Procedure 71.
(c) Gradation Element. Each specified sieve, with the exception of 100 percent passing sieves, will be evaluated for QL
separately. The lowest calculated QL for a sieve will be designated as the QL for gradation element for the process.
(d) Joint Density Element. Joint Density will be tested according to subsection 401.17.
(e) Process Pay Factor. Using the calculated QL for the process, compute PF as follows: The final number of random
samples (Pn) in each process will determine the final pay factor. . As test values are accumulated for each process, Pn
will change accordingly. When the process has been completed, the number of random samples it contains will
determine the computation of PF, based on Table 105-3 and formula (1) below. When Pn is from 3 to 9, or greater than
200, PF will be computed using the formulas designated in Table 105-3. Where Pn is equal to or greater than 10 and
less than 201, PF will be computed by formula (1):
Where, when referring to Table 105-3:
PF1
= PF determined at the next lowest Pn formula using process QL
PF2
= PF determined using the Pn formula shown for the process QL
PF3
= PF determined at the next highest Pn formula using process QL
Pn2
= the lowest Pn in the spread of values listed for the process Pn formula
Pn3
= the lowest Pn in the spread of values listed for the next highest Pn formula
PnX
= the actual number of test values in the process
When evaluating the item of Furnish Hot mix asphalt, the PF for the element of In-Place Density shall be 1.0.

North College Rear Access Road Improvement Project
Project Special Provisions May 2014
97
Regardless of QL, the maximum PF in relation to Pn is limited in accordance with Table 105-3.
As test results become available, they will be used to calculate accumulated QL and PF numbers for each process. The
process I/DP’s will then be calculated and accumulated for each element and for the item. The test results and the
accumulated calculations will be made available to the Contractor upon request.
Numbers from the calculations will be carried to significant figures and rounded according to AASHTO Standard
Recommended Practice R-11, Rounding Method.
(f) Evaluation of Work. When the PF of a process is 0.75 or greater, the finished quantity of work represented by the
process will be accepted at the appropriate pay factor. If the PF is less than 0.75, the Engineer may:
1. Require complete removal and replacement with specification material at the Contractor’s expense;
or
2. Where the finished product is found to be capable of performing the intended purpose and the value of the finished
product is not affected, permit the Contractor to leave the material in place.
If the material is permitted to remain in place the PF for the process will not be greater than 0.75. When condition red,
as described in Section 106, exists for any element, resolution and correction will be in accordance with Section 106.
Material, which the Engineer determines is defective, may be isolated and rejected without regard to sampling sequence
or location within a process.
If removal and replacement is required because the joint density PF for a process is below 0.75, the Contractor shall
remove and replace the full lane width adjacent to and including at least 6 inches beyond the visible joint line for the
entire length of joint representing the process. If the lane removed is adjacent to another joint, that joint shall also be
removed to a point 6 inches beyond the visible joint line. When a single joint density core is more than 2V outside the
tolerance limits, the removal and replacement limits shall be identified by coring the failing joint at 25 foot intervals until
two successive cores are found to be 1V or less below the minimum tolerance limit. If removal and replacement is
required, the Contractor shall submit documentation identifying the process to be used to correct the area in question in
writing. The process will be approved by the Engineer before commencing the corrective work.

106.05 Sampling and Testing of Hot Mix Asphalt. All hot mix asphalt, Item 403, except Hot Mix Asphalt (Patching) and
temporary pavement shall be tested in accordance with the following program of process control testing and acceptance
testing:
The Contract will specify whether process control testing by the Contractor is mandatory or voluntary.
(a) Process Control Testing.
1. Mandatory Process Control. When process control testing is mandatory the Contractor shall be responsible for
process control testing on all elements and at the frequency listed in Table 106-1. Process control testing shall be
performed at the expense of the Contractor.
After completion of compaction, in-place density tests for process control shall be taken at the frequency
shown in Table 106-1. The results shall be reported in writing to the Engineer on a daily basis. Daily
plots of the test results with tonnage represented shall be made on a chart convenient for viewing by the
Engineer. All of the testing equipment used for in-place density testing shall conform to the requirements
of acceptance testing standards, except nuclear testing devices need not be calibrated on the
Department’s calibration blocks.
For elements other than in-place density, results from quality control tests need not be plotted, or
routinely reported to the Engineer. This does not relieve the Contractor from the responsibility of
performing such testing along with appropriate plant monitoring as necessary to assure that produced
material conforms to the applicable specifications. Quality control test data shall be made available to the
Engineer upon request.
2. Voluntary Process Control. The Contractor may conduct process control testing. Process control testing is not
required, but is recommended on the elements and at the frequency listed in Table 106-1.
All of the testing equipment used for in-place density testing shall conform to the requirements of
acceptance testing standards, except nuclear testing devices need not be calibrated on the Department’s
calibration blocks.

(b) Acceptance Testing. Acceptance testing is the responsibility of the Department. For acceptance testing the Department
will determine the locations where samples or measurements are to be taken and as designated in Section 403. The
maximum quantity of material represented by each test result, the elements, the frequency of testing and the minimum
number of test results will be in accordance with Table 106-1. The location or time of sampling will be based on the
stratified random procedure as described in CP 75. Acceptance sampling and testing procedures will be in accordance
with the Schedule for Minimum Materials Sampling, Testing and Inspection in the Department’s Field Materials
Manual. Samples for project acceptance testing shall be taken by the Contractor in accordance with the designated
method. The samples shall be taken in the presence of the Engineer. Where appropriate, the Contractor shall reduce
each sample to the size designated by the Engineer. The Contractor may retain a split of the each sample which cannot
be included as part of the Contractor’s process control testing. All materials being used are subject to inspection and
testing at any time prior to or during incorporation into the work.

(b) Process control tests for gradation are not required if less than 250 tons are
placed in a day. The minimum number of process control tests for gradation
shall be one test for each 1000 tons or fraction thereof.
(c) Not to be used for incentive/disincentive pay. Test according to CP 60B and
report results from Form 106 or Form 565 on Form 6.
(d) Verified per Contractor’s QC Plan.
(c) Reference Conditions. Three reference conditions can exist determined by the Moving Quality Level (MQL). The MQL
will be calculated in accordance with the procedure in CP 71 for Determining Quality Level (QL). The MQL will be
calculated using only acceptance tests. The MQL will be calculated on tests 1 through 3, then tests 1 through 4, then
tests 1 through 5, then thereafter on the last five consecutive test results. The MQL will not be used to determine pay
factors. The three reference conditions and actions that will be taken are described as follows:
1. Condition green will exist for an element when an MQL of 90 or greater is reached, or maintained, and the past five
consecutive test results are within the specification limits.
2. Condition yellow will exist for all elements at the beginning of production or when a new process is established
because of changes in materials or the job-mix formula, following an extended suspension of work, or when the
MQL is less than 90 and equal to or greater than 65. Once an element is at condition green, if the MQL falls below
90 or a test result falls outside the specification limits, the condition will revert to yellow or red as appropriate.
North College Rear Access Road Improvement Project
Project Special Provisions May 2014
101
3. Condition red will exist for any element when the MQL is less than 65. The Contractor shall be notified immediately
in writing and the process control sampling and testing frequency increased to a minimum rate of 1/250 tons for that
element. The process control sampling and testing frequency shall remain at 1/250 tons until the process control QL
reaches or exceeds 78. If the QL for the next five process control tests is below 65, production will be suspended.
If gradation is the element with MQL less than 65, the Department will test one randomly selected sample in the first
1250 tons produced in condition red. If this test result is outside the tolerance limits, production will be suspended.
(This test result will not be included as an acceptance test.)
After condition red exists, a new MQL will be started. Acceptance testing will stay at the frequency shown in Table
106-1. After three acceptance tests, if the MQL is less than 65, production will be suspended.
Production will remain suspended until the source of the problem is identified and corrected. Each time production
is suspended, corrective actions shall be proposed in writing by the Contractor and approved in writing by the
Engineer before production may resume.
Upon resuming production, the process control sampling and testing frequency for the elements causing the
condition red shall remain at 1/250 tons. If the QL for the next five process control tests is below 65, production
will be suspended again. If gradation is the element with MQL less than 65, the Department will test one randomly
selected sample in the first 1250 tons produced in condition red. If this test result is outside the tolerance limits,
production will be suspended.

REVISION OF SECTION 401
TEMPERATURE SEGREGATION
Section 401 of the Standard Specifications is hereby revised for this project as follows:
In subsection 401.16 delete the twelfth (last) paragraph and replace it with the following:
The Engineer may evaluate the HMA for low density due to temperature segregation any time industry best
practices, as detailed on Form 1346, are not being followed or the Engineer suspects temperature segregation is
occurring. The Engineer will first meet with the Contractor to discuss the paving practices that are triggering the
temperature investigation. Areas across the mat, excluding the outside 1 foot of both edges of the mat, that are
more than 25 °F cooler than other material across the width may be marked for density testing. Material for
temperature comparison will be evaluated in 3-foot intervals behind the paver across the width of the mat. The
material shall be marked and tested in accordance with CP 58. If four or more areas within a lot of 500 tons have
densities of less than 93 percent of the material’s maximum specific gravity for SMA mixes or less than 92
percent of the material’s maximum specific gravity for all other HMA mixes, a 5 percent price disincentive will
be applied to the 500 ton lot. The 500 ton count begins when the Engineer starts looking for cold areas, not when
the first cold area is detected. This price disincentive will be in addition to those described in Sections 105 and
106. Only one area per delivered truck will be counted toward the number of low density areas. Temperature
segregation checks will be performed only in areas where continuous paving is possible.
