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.
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.
Midway Drive Roadway 01010-2 Summary of Work
and Water Line Improvements
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 excepted) 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, 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.
The Contractor shall not be charged with liquidated damages or any excess cost when
the delay in completion of the work is due to the following, and the Contractor has
promptly given written notice of such delay to the Owner or Engineer.

SUBMITTALS
PART 1 GENERAL
1.01 SECTION INCLUDES
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, six (6)
copies of each submittal and sample are required, four (4) 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.
Midway Drive Roadway 01330-2 Submittals
and Water Line Improvements
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, 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 matter 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:
Midway Drive Roadway 01330-3 Submittals
and Water Line Improvements
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 “FURNISH 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 “FURNISH
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 “FURNISH 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
Midway Drive Roadway 01330-4 Submittals
and Water Line Improvements
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.
E. Certificates:
For those items called for in individual sections, furnish six (6) certificates of
compliance from manufacturers or suppliers certifying that materials or equipment
being furnished under the Contract comply with the requirements of these
Specifications.
F. Samples:
Samples shall be sufficient in size to clearly illustrate functional characteristics and
full range of color, texture, and pattern.
G. Effect of Review of CONTRACTOR’s Submittals:
Review of drawings, data, methods of work, or information regarding materials or
equipment the CONTRACTOR proposes to provide, shall not relieve the contractor
of its responsibility for errors therein and shall not be regarded as an assumption of
risks or liability by the ENGINEER or the OWNER, or by any officer or employee
thereof, and the CONTRACTOR shall have no claim under the Contract on account
of the failure or partial failure, of the method of work, material, or equipment so
reviewed. A mark of “NO EXCEPTIONS TAKEN” or “FURNISH AS NOTED”
shall mean that the OWNER has no objection to the CONTRACTOR, upon its own
responsibility, using the plan or method of work proposed, or providing the materials
or equipment proposed.

WATER CONTROL AND DEWATERING
PART 1 GENERAL
1.01 SECTION INCLUDES
A. The work of this section consists of controlling groundwater, site drainage, and storm
flows during construction. The CONTRACTOR is cautioned that the work involves
construction in and around drainage channels, local streams or rivers, and areas of local
drainage. These areas are subject to frequent periodic inundation.
1.02 RELATED SECTIONS
A. Section 02315 – Excavation and Embankments
PART 2 PRODUCTS
2.01 MATERIALS
A. On-site materials may be used within the limits of construction to construct temporary
dams and berms. The materials such as plastic sheeting, sand bags, and storm sewer
pipe may also be used if desired by the CONTRACTOR.
PART 3 EXECUTION
3.01 CONSTRUCTION REQUIREMENTS
A. General: For all excavation, the CONTRACTOR shall provide suitable equipment and
labor to remove water, and he shall keep the excavation dewatered so that construction
can be carried on under dewatered conditions where required by the Drawings and
Specifications. Water control shall be accomplished such that no damage is done to
adjacent channel banks or structures. The CONTRACTOR is responsible for
investigating and familiarizing himself with all site conditions that may affect the work
including surface water, level of groundwater and the time of year the work is to be
done. All excavations made as part of dewatering operations shall be backfilled with
the same type material as was removed and compacted to 95% of Maximum Standard
Proctor Density (ASTM D698) except where replacement by other materials and/or
methods are required. The cost for this excavation and backfilling shall be included in
the Construction Dewatering bid item.
The CONTRACTOR shall conduct his operation in such a manner that storm or other
waters may proceed uninterrupted along their existing drainage courses. By submitting
a bid, the CONTRACTOR acknowledges that he has investigated the risk arising from
such waters and has prepared his bid accordingly, and assumes all of said risk.
At no time during construction shall the CONTRACTOR affect existing surface or
subsurface drainage patterns of adjacent property. Any damage to adjacent property
resulting from the CONTRACTOR’s alteration of surface or subsurface drainage
patterns shall be repaired by the CONTRACTOR at no additional cost to the OWNER.
CONTRACTOR shall remove all temporary water control facilities when they are no
longer needed or at the completion of the project.
Midway Drive Roadway 02240-2 Water Control and Dewatering
and Water Line Improvements
Pumps and generators used for dewatering and water control shall be quiet equipment
enclosed in sound deadening devices.
B. Surface Water Control: Surface water control generally falls in to the following
categories:
1. Normal low flows along the channel;
2. Storm/flood flows along the channel;
3. Flows from existing storm drain pipelines; and,
4. Local surface inflows not conveyed by pipelines.
The CONTRACTOR shall coordinate, evaluate, design, construct, and maintain
temporary water conveyance systems. These systems shall not worsen flooding, alter
major flow paths, or worsen flow characteristics during construction. The
CONTRACTOR is responsible to ensure that any such worsening of flooding does
not occur. The CONTRACTOR is solely responsible for determining the methods
and adequacy of water control measures.
At a minimum, the CONTRACTOR will be responsible for diverting the quantity of
surface flow around the construction area so that the excavations will remain free of
surface water for the time it takes to install these materials, and the time required for
curing of any concrete or grout. The CONTRACTOR is cautioned that the minimum
quantity of water to be diverted is for erosion control and construction purposes and
not for general protection of the construction-site. It shall be the CONTRACTOR's
responsibility to determine the quantity of water which shall be diverted to protect his
work from damage caused by storm water.
The CONTRACTOR shall, at all times, maintain a flow path for all channels.
Temporary structures such as berms, sandbags, pipeline diversions, etc., may be
permitted for the control of channel flow, as long as such measures are not a major
obstruction to flood flows, do not worsen flooding, or alter historic flow routes.
C. Groundwater Control: The CONTRACTOR shall install adequate measures to
maintain the level of groundwater below the foundation subgrade elevation and
maintain sufficient bearing capacity for all structures, pipelines, earthwork, and rock
work. Such measures may include, but are not limited to, installation of perimeter
subdrains, pumping from drilled holes or by pumping from sumps excavated below
the subgrade elevation. The foundation bearing surfaces are to be kept dewatered
and stable until the structures or other types of work are complete and backfilled.
Disturbance of foundation subgrade by CONTRACTOR operations shall not be
considered as originally unsuitable foundation subgrade and shall be repaired at
CONTRACTOR’s expense.
Any temporary dewatering trenches or well points shall be restored following
dewatering operations to reduce permeability in those areas as approved by the
ENGINEER.
CONTRACTOR is to restore any areas disturbed by the dewatering operations to
their original condition.

ENGINEER will determine which type of aggregate or other material which shall be
used after observing the specific site conditions.
PART 3 EXECUTION
3.01 GENERAL EXCAVATION/EMBANKMENT
A. General: The excavation and embankment for the project work shall be finished to
reasonably smooth and uniform surfaces. Variation from the subgrade plane shall not
be more than .08 feet in soil or more than .08 feet above or .50 below in rock. Where
bituminous or concrete surfacing materials are to be placed directly on the subgrade,
the subgrade plane shall not vary more than 0.04 feet. Materials shall not be wasted
without permission of the ENGINEER. Excavation operations shall be conducted so
that material outside of the limits of slopes will not be disturbed. Prior to beginning
grading operations in any area, all necessary clearing and grubbing in that area shall
have been performed in accordance with Section 02230 of these Specifications.
When the CONTRACTOR’s excavating operations encounter remains of pre-historic
people’s dwelling sites or artifacts of historical or archaeological significance, the
operations, shall be temporarily discontinued. The ENGINEER will contact
archaeological authorities to determine the disposition thereof. When directed, the
CONTRACTOR shall excavate the site in such a manner as to preserve the artifacts
encountered and shall remove them for delivery to the custody of the proper state
authorities. Such excavation will be considered and paid for as extra work.
B. Excavation:
1. Unclassified: All excess suitable material excavated from the project site
and not used for embankment shall be removed from the project site and
become the property of the CONTRACTOR. Where material encountered
Midway Drive Roadway 02315-3 Excavation and Embankment
and Water Line Improvements
within the limit of the work is considered unsuitable for embankment (fills)
on any portion of this project work, such material shall be excavated as
directed by the ENGINEER and replaced with suitable fill material. All
unsuitable excavated material from excavation consisting of any type of
debris (surface or buried), excavated rock, bedrock or rocks larger than 6
inches in diameter and boulders shall be hauled from the project site and
disposed of. Debris is defined as “anything that is not earth which exists at
the job site”.
2 . Muck: Where excavation to the finished grade section results in a subgrade
or slopes of unsuitable soil, the ENGINEER may require the
CONTRACTOR to remove the unsuitable materials and backfill to the
finished graded section with approved material. Disposal of the material
shall be at the CONTRACTOR’s expense.
Good surface drainage shall be provided around all permanent cuts to direct
surface runoff away from the cut face.
3. Rock: Unless otherwise specified, rock shall be excavated to a minimum
depth of 0.5 feet below subgrade within the limits of the channel area, and
the excavation shall be backfilled with material shown on the Drawings or as
designated by the ENGINEER. Disposal of material and replacement with
suitable approved material shall be at the CONTRACTOR’s expense.
C. Embankment Construction: Embankment construction shall consist of constructing
all fill areas, including preparation of the areas upon which they are to be placed, and
the placing and compacting of embankment material in holes, pits and other
depressions within the project area. Only approved materials shall be used in the
construction of embankments and backfills.
Approved materials shall consist of clean on-site cohesive soils or approved imported
soils. On-site cohesive soils are suitable for use as compacted fill provided the
following recommendations are met:
Percent Finer by Weight
Gradation (ASTM C136)
½-Inch 100
3/8-Inch 70 – 100
No. 4 Sieve 50 – 100
No. 200 Sieve 60 (min)
• Liquid Limit 35 (max)
• Plasticity Index 20 (max)
• In-Situ Coefficient of Permeability 1x10-6 cm/sec
Excavation and Embankment will only be paid when a significant change in grade is
required, as determined by the ENGINEER. Minor cuts and fills will be considered
incidental to the work, and will not be paid for separately under this section.
Midway Drive Roadway 02315-4 Excavation and Embankment
and Water Line Improvements
On-site cohesive soils or imported soils should be placed and compacted in
horizontal lifts, using equipment and procedures that will produce recommended
moisture contents and densities throughout the lift and embankment height. On-site
or imported cohesive soils should be compacted within a moisture content range of
2% below, to 2% above optimum moisture content and compacted to 95% of the
Maximum Standard Proctor Density (ASTM D698).
When embankment is to be placed and compacted on hillsides, or when new
embankment is to be compacted against existing embankments, or when embankment
is built 1/2 width at a time, the slopes that are steeper than 4:1 when measured
longitudinally or at right angles to the adjacent ground shall be continuously benched
over those areas where it is required as the work is brought up in layers. Benching
shall be well keyed and where practical a minimum of 8 feet. Each horizontal cut
shall begin at the intersection of the original ground and the vertical sides of the
previous cuts. Material thus cut out shall be recompacted along with the new
embankment material at the CONTRACTOR’s expense.
The ground surface underlying all fills shall be carefully prepared by removing all
organic matter, scarification to a depth of 8 inches and recompacting to 95% of the
Maximum Standard Proctor Density (ASTM D698) at optimum moisture content +
or - 2% prior to fill placement.
Embankment material shall be placed in horizontal layers not exceeding 8 inches
(loose measurement) and shall be compacted to 95% of the Maximum Standard
Proctor Density (ASTM D698) at optimum moisture content + or - 2%. Effective
spreading equipment shall be used on each lift to obtain uniform thickness prior to
compacting. As the compaction of each layer progresses, continuous leveling and
manipulating will be required to assure uniform density.
For embankments which serve as berms, the downstream portion shall be “keyed”
into the subsurface soils a minimum of 3 feet to enhance the stability of the slope.
Materials which are removed from excavations beneath the water table may be over
the optimum moisture content and will require that they be dried out prior to reusing
them.
Cross hauling or other action as appropriate will be ordered when necessary to insure
that the best available material is placed in critical areas of embankments, including
the top 2 feet of all embankments. No additional payment will be made for cross
hauling ordered by the ENGINEER.
Frozen materials shall not be used in construction of embankments.
During the construction of channels, the channel bottom shall be maintained in such
condition that it will be well drained at all times.
Excavation or Embankment (Fill), and Structural Backfill work either completed or
in a stage of completion that is either eroded or washed away or becomes unstable
due to either rains, snow, snow melt, channel flows or lack of proper water control
shall be either removed and replaced, recompacted or reshaped as directed by the
Midway Drive Roadway 02315-5 Excavation and Embankment
and Water Line Improvements
ENGINEER and in accordance with the Drawings and Specifications at the
CONTRACTOR’s sole expense. Removed unsuitable materials shall be hauled away
and disposed of at the CONTRACTOR’s expense. Placing of replacement materials
for removed unsuitable materials shall be purchased, placed and compacted at the
CONTRACTOR’ expense.
D. Proof rolling with a heavy rubber tired roller will be required, if designated on the
Drawings or when ordered by the ENGINEER. Proof rolling shall be done after
specified compaction has been obtained. Areas found to be weak and those areas
which failed shall be ripped, scarified, wetted if necessary, and recompacted to the
requirements for density and moisture at the CONTRACTOR’s expense.
Proof rolling shall be done with equipment and in a manner acceptable to the
ENGINEER. Proof rolling as shown on the Drawings or as ordered by the
ENGINEER shall not be measured and paid for separately, but shall be included in
the unit prices bid for the work.
3.02 EXCAVATION AND BACKFILL FOR STRUCTURES
A. Poor foundation material for any of the work shall be removed, by the
CONTRACTOR, as directed by the ENGINEER. The CONTRACTOR will be
compensated for removal and replacement of such materials in accordance with
Muck Excavation.
The CONTRACTOR is cautioned that construction equipment may cause the natural
soils to pump or deform while performing excavation work inside and on footings,
structural floor slabs, or other structure foundation areas.
Foundation materials which are: a) saturated by either surface or subsurface flows
due to the lack of adequate water control or dewatering work by the
CONTRACTOR; b) frozen for any reason; or, c) that are disturbed by the
CONTRACTOR’s work or caused to become unacceptable for foundation material
purposes by means of the CONTRACTOR’s equipment, manpower, or methods of
work shall be removed and replaced by the CONTRACTOR at his expense.
Dewatering should not be conducted by pumping from inside footing, structural floor
slab, or other structure foundation limits. This may decrease the supporting capacity
of the soils.
Care should be taken when excavating the foundations to avoid disturbing the
supporting materials. Excavation by either hand or careful backhoe soil removal,
may be required in excavating the last few inches of material to obtain the subgrade
of any item of the concrete work.
Any over-excavated subgrades that are due to the CONTRACTOR’s actions, shall be
brought back to subgrade elevations by the CONTRACTOR and at his expense in the
following manner:
Midway Drive Roadway 02315-6 Excavation and Embankment
and Water Line Improvements
1. For over-excavations of 2 inches or less, either: Backfill and compact with
an approved granular materials; backfill with 1/2 inch crushed rock; or fill
within concrete at the time of the appurtenant structure concrete pour.
2. For over-excavations greater than 2 inches, backfill and compact with an
approved granular material.
All granular footings, structural floor slabs, or other structure areas shall be
compacted with a vibratory plate compactor prior to placement of concrete,
reinforcing, or bedding materials.
B. Backfill, and fill within 2 feet of and adjacent to all structures and for full height of
the walls, shall be selected non-swelling material. It shall be granular, well graded,
and free from stones larger than 3 inches. Material may be job excavated, but
selectivity will be required as determined by the ENGINEER. Refer to the Drawings
for job specific requirements. Stockpiled material, other than topsoil from the
excavation shall be used for backfilling unless an impervious structural backfill is
specified. The backfill material shall consist of either clean on-site granular materials
free of stones larger than 3 inches in diameter with no more than 20% passing the No.
200 sieve, or equivalent imported materials. All backfill around the structures shall
be consolidated by mechanical tamping. The material shall be placed in 8-inch loose
lifts within a range of 2% above to 2% below the optimum moisture content and
compacted to 95% of Maximum Standard Proctor Density (ASTM D698) for
cohesive soils, or to 70% relative density for pervious material as determined by the
relative density of cohesionless soils test, ASTM D4253.
When specified on the Drawings or as required by the ENGINEER, Class I structural
backfill shall meet the following gradation requirements:
% by Weight Passing
Sieve Size Square Mesh Sieves
2-Inch 100
No. 4 30 - 100

be stripped within the area to be aggregate surfaced. Following stripping of the
topsoil, the upper 12 inches of the subgrade shall be scarified and compacted to a
minimum of 95% of the Maximum Standard Proctor Density (ASTM D698). On-
site material may be used as accepted by the ENGINEER, for compacted fill for the
aggregate base course. Fill shall be placed within 2% of optimum moisture content
and compacted to a minimum of 95% of the Maximum Standard Proctor Density
(ASTM D698).
Aggregate base course used as a foundation for pavements shall be placed on the
subgrade within two percent of optimum moisture and compacted to a minimum of
95% of the Maximum Standard Proctor Density (ASTM D698). The top six inches
of topsoil shall be stripped within the area to be aggregate surfaced. Following
stripping of the topsoil, the upper 12 inches of the subgrade shall be scarified and
compacted to a minimum of 95% of the Maximum Standard Proctor Density (ASTM
D698). On-site material may be used, as accepted by the ENGINEER, for compacted
fill for the aggregate base course. Fill shall be placed within 2% of optimum
moisture content and compacted to a minimum of 95% of the Maximum Standard
Proctor Density (ASTM D698). Deviations in aggregate base course under
pavements of more than 1/4 inch in 10 feet, measured with a 10-foot straight edge,
shall be corrected prior to pavement construction.
The foundation shall be prepared and constructed such that it will have a uniform
density throughout. It shall be brought to the required alignment and cross section
with equipment and methods adapted for the purpose. Upon completion of the
shaping and compacting operations, the foundation shall be smooth, at the required
density, and at the proper elevation and contour to receive the aggregate base course.
After the specified compaction has been obtained, the subgrade under the curb,
gutter, sidewalk and pavement shall be proof-rolled with a heavily loaded rubber tire
roller, fully loaded water truck, or other approved equipment. Those areas which
produce a rut depth of over ½ inch or which crack the subgrade after pumping and
rebounding shall be ripped, scarified, wetted or dried if necessary, and recompacted
to the requirements for density and moisture at the CONTRACTOR’S expense.
Where unsuitable material is encountered, the ENGINEER may require the
CONTRACTOR to remove the unsuitable materials and backfill to the finished grade
with approved material. The completed subgrade shall be proof-rolled again after
placement of approved material.
Unless otherwise provided, all holes, ruts and other depressions in the foundation
shall be filled with materials similar to those existing in the foundation. High places
shall be excavated and removed to the required lines, grade and section.
Base course material shall not be placed on a foundation that is soft, spongy, or one
that is covered by ice or snow. Base course shall not be placed on a dry or dusty
foundation where the existing condition would cause rapid dissipation of moisture
from the base course material and hinder or preclude its proper compaction. Dry
foundations shall have water applied and reworked and compacted as necessary.
The ENGINEER shall direct the CONTRACTOR to make minor adjustments in the
finish grade from that shown in the Drawings as may be necessary or desirable to
maintain the characteristics of a stabilized foundation by minimizing the amount of
cutting into or filling.
Midway Drive Roadway 02710-4 Aggregate Base Course
and Water Line Improvements
3.02 EARTH SUBGRADE
A. When the foundation is an earth subgrade it shall be prepared by removing all
vegetation, excavating and removing materials, filling depressions, scarifying,
shaping, smoothing and compacting to meet the required grade, section and density.
Stones over six inches in greatest dimension shall be removed.
3.03 PLACEMENT
A. The aggregate base course shall be constructed to the width and section shown in the
Drawings. If the required compacted depth of base coarse exceeds six inches, the
base shall be constructed in two or more layers of approximate equal thickness. The
maximum compacted thickness of any one layer shall not exceed six inches.
Each layer shall be constructed as far in advance of the succeeding layer as the
ENGINEER may direct. The work shall, in general, proceed from the point on the
project nearest the point of supply of the aggregate in order that the hauling
equipment may travel over the previously placed material, and the hauling equipment
shall be routed as uniformly as possible over all portions of the previously
constructed courses or layers of the base course.
The material shall be deposited on the soil foundation, or previously placed layer in a
manner to minimize segregation and to facilitate spreading to a uniform layer of the
required section. In the event that blending of materials is necessary to provide
required gradation and properties of the material, and is done in the roadway, the
same shall be accomplished by mixing the aggregate and blending material by means
of blade graders, discs, harrows or other equipment to effect a uniform distribution
and gradation throughout the finished mixture. Excessive mixing and grading that
will cause segregation between the coarse and fine materials is prohibited.
3.04 COMPACTION
A. After a layer or course has been placed and spread to the required thickness, width
and contour, it shall be compacted. If the material is too dry to readily attain the
required density, it shall be uniformly moistened to the degree necessary during
compaction operations for proper compaction.
B. Compaction of each layer shall continue until the required density of Section 3.01 is
reached. The surface of each layer shall be maintained during compaction operations
in such a manner that a uniform texture is produced and aggregates firmly keyed.
All areas where proper compaction is not obtainable due to segregation of materials,
excess fines, or other deficiencies in the aggregate, shall be reworked as necessary or
the material removed and replaced with aggregates that will meet this specification.
The surface of each layer shall be kept true and smooth at all times.
3.05 MIXING
A. General: Unless otherwise specified, the CONTRACTOR shall mix the aggregate by
any one of the three following methods.
Midway Drive Roadway 02710-5 Aggregate Base Course
and Water Line Improvements
1. Stationary Plant Method:
Aggregate base course and water shall be mixed in an approved mixer. After
mixing the aggregate shall be transported to the project site while it contains
the proper moisture content and shall be placed on the roadbed by means of
an approved spreader.
2. Travel Plant Method
After the material for each layer has been placed through an aggregate
spreader or windrow sizing device, it shall be uniformly mixed by a traveling
mixing plant.
3. Road Mix Method
After material for each layer has been placed, the materials shall be mixed
while at an optimum moisture content by motor graders or other approved
equipment until the mixture is uniform throughout.
3.06 SHOULDER CONSTRUCTION
A. Shoulders shall be constructed with base course material to conform to the elevation
and section shown in the Drawings. No equipment shall be used which by its design
or through its manner of operation that will damage the pavement or curbs. Insofar
as practicable, the base course material shall be placed directly on the shoulder area.

at the paving plant so that when delivered to the mixer, they shall be at as low a
temperature as is consistent with proper mixing and laying, and in no case to exceed
350oF. They may be fed simultaneously into the same drier but in all cases,
immediately after heating, they shall be screened into three or more bins. The screen
sizes shall be approved by the ENGINEER prior to the start of construction.
C. Preparation and Composition of the Mixture: Each size of hot aggregate, the mineral
filler and the asphalt cement shall be measured separately and accurately to the
proportions in which they are to be mixed. After the hot aggregate and mineral filler
have been charged into the mixer and thoroughly mixed as directed by the
ENGINEER, the asphalt cement shall be added and the mixing continued for a period
of at least 20 seconds, or longer if necessary, to produce a homogeneous mixture, in
which all particles of the mineral aggregates are coated uniformly.
D. Paving Plant Inspection: For the verification of weights or proportions and character
of materials and determination of temperatures used in the preparation of the mixture,
the ENGINEER or his authorized representative shall have access at any time to all
parts of the paving plant.
PART 3 EXECUTION
3.01 SURFACE PREPARATION
A. All final pavement cuts shall be made in straight lines using saw cut. Initial
pavement cuts may be made using wheel cut or other suitable method.
West Prospect Ponds – Phase 1 02740-7 Flexible Pavement

B. Prior to placing the prime coat, the base course shall be thoroughly cleaned. Loose
material shall be removed from the existing surface as directed by the ENGINEER.
3.02 PRIME COAT
A. All previously prepared bases or existing surface shall be primed with a cationic
emulsified asphalt in accordance with the requirements of these Specifications or as
directed by the ENGINEER. The prime coat shall be placed by means of an
approved pressure distributor. Before application, the asphaltic oil shall be heated as
directed by the ENGINEER. However, it shall not be heated to more than 180OF. In
general, the rate of application shall be from 0.25 to 0.35 gallons per square yard as
directed by the ENGINEER. The prime coat shall be carefully applied, particularly
around curbs and sidewalks. If excessive amounts of curb, sidewalks, or other
structures are sprayed with asphaltic oil, they shall be cleaned as directed by the
ENGINEER at the CONTRACTOR’s expense. All vertical contact faces shall be
primed by painting with cationic emulsified asphaltic oil.
3.03 ASPHALTIC CONCRETE SURFACE
A. Transportation of Mixture: The mixture shall be transported from the paving plant to
the work in vehicles equipped with tight metal compartments previously cleaned of
all foreign materials. When directed by the ENGINEER, the compartments shall be
sufficiently insulated and each load shall be covered with canvas or other suitable
materials of sufficient size to protect it from weather conditions. The inside surface
of all vehicle compartments used for hauling mixture must be lightly lubricated with
a tin oil or soap solution just before loading, but excess lubricant will not be
permitted. No load shall be sent out so late in the day as to interfere with spreading
and compacting the mixture during daylight unless artificial light, satisfactory to the
ENGINEER, is provided.
B. General Conditions: The mixture shall be laid only when the base is dry and only
when weather conditions are suitable. The mixture shall be laid when atmospheric
temperatures are consistent with the placement temperature limitations as outlined on
page 02740-10. Asphalt shall not be placed when frost exists in the subgrade. Any
material laid shall be rolled with pneumatic rollers in addition to the specified rolling,
as directed by the ENGINEER.
C. Placing Asphalt Mixture: If traffic is allowed to use the prepared subgrade or sub-
base, the subgrade or sub-base shall be checked and corrected as needed immediately
ahead of placing bituminous materials. Prior to placement of the bituminous surface,
the base shall be cleaned of all dirt or other foreign matter. When the new pavement
abuts the old pavement, the CONTRACTOR shall cut the old pavement as directed
by the ENGINEER and paint the edge of the pavement with a tack coat.

The asphaltic pavement shall be placed only when the base is stable and weather
conditions are suitable. The asphaltic pavement shall have a density of ninety-five
percent (95%) of a representative laboratory compacted specimen by the Hveem
method as tested in accordance with ASTM Method 2950-B2 and ASTM D 2726-83.
While the surface is being compacted and finished, the CONTRACTOR shall
carefully trim the outside edges of the pavement to the proper alignment.
Unless otherwise permitted by the ENGINEER, the mixture shall be spread by means
of a mechanical self-powered paver, capable of spreading the mixture true to the line,
grade, and crown set by the ENGINEER.
Pavers shall be equipped with hoppers and distributing screws of the reversing type
to place the mixture evenly in front of adjustable screeds. The mixture shall be
dumped in the center of the hoppers and care exercised to avoid overloading and
spilling over of the mixture upon the base. Pavers shall operate when laying mixtures
at such speed between 10 feet and 20 feet per minute, as may be decided by the
ENGINEER.
Pavers shall be equipped with a quick and efficient steering device and shall have
forward and reverse speeds of not less than 100 feet per minute.
Unless operating on fixed side forms, pavers shall employ mechanical devices such
as equalizing runners, straightedge runners, evener arms, or other compensating
devices to adjust the grade and confine the edges of the mixture to true lines within
the use of stationary side forms. The pavers shall be capable of spreading the
mixtures, without segregation, in thickness of from ½ inch to 3 inches, to a maximum
width of 10 feet in increments of 1 foot or less and to a minimum width of 8 feet.
They shall be equipped with blending or joint leveling devices for smoothing and
adjusting all longitudinal joints between adjacent strips of courses of the same
thickness.
When asphalt concrete pavement thickness in excess of 2 inches is called for, they
shall be laid in separate courses of not less than 1 inch or more than 2 inches or as
directed by the ENGINEER.
West Prospect Ponds – Phase 1 02740-9 Flexible Pavement
10/05/04
The term “screed” includes a “strike-off” device operating by cutting, crawling, or
other practical action which is effective on the mixture at a workable temperature
without tearing, shoving, or gouging and which produces a finished surface of the
evenness and texture specified. The screed shall be adjustable as to level and shall
have an indicating level attached. Longitudinal and transverse joints shall be made in
a careful manner. Well bonded and sealed joints are required. If necessary to obtain
this result, joints shall be painted with cationic emulsified asphaltic cement.
In making the joint along any adjoining edges such as curb, gutter, or an adjoining
pavement and after the hot mixture is placed by the finished machine, just enough of
the hot material shall be carried back to fill any space left open. This joint shall be
properly “set” up with the back of rake at proper height and level to receive the
maximum compression under rolling. The work of “setting up” this joint shall be
performed always by competent workmen who are capable of making correct, clean,
and neat joints.
Immediately after any course is screeded, and before roller compaction is started, the
surface shall be checked, any inequalities adjusted, all fat, sandy accumulations from
the screed removed by a rake or hoe, and all fat spots in any course removed and
replaced with satisfactory material. Irregularities in alignment and grade along the
outside edge shall also be corrected by the addition or removal of mixture before the
edge is rolled.
In narrow, deep, or irregular sections, intersections, turnouts, or driveways where it is
impractical to spread and finish the mixtures by machine methods, the
CONTRACTOR may used approved spreading equipment or acceptable hand
methods as directed by the ENGINEER.
When the mixture is to be spread by hand, upon arrival on the work it shall be
dumped upon a steel dump board outside the area on which it is to be spread.
Immediately thereafter it shall be distributed into place by means of hot shovels and
spread with hot rakes in a loose layer of uniform density and correct depth. Tines of
the rakes shall not be less than ½ inch longer than the loose depth of the mixture, and
spaces between tines shall not be less than the maximum diameter of aggregate
particle except that in no case should the spaces be less than 1 inch. Loads shall not
be dumped any faster than can be properly handled by the shovelers.
The shovelers shall not distribute the dumped load faster than it can be properly
handled by the rakers.
The rakers will not be permitted to stand in the hot mixture while raking it, except
where necessary to correct errors in the first raking. The raking must be carefully
and skillfully done in such a manner that after the first passage of the roller over the
raked mixture, a minimum amount of back patching will be required.
Placing mixtures shall be as continuous as possible and the roller shall pass over the
unprotected edge of the freshly laid mixture only when the laying of this course is to
be discontinued for such intervals of time as to permit the mixture to become chilled.
D. Joints: Joints between old and new pavements, or between successive days’ work,
shall be carefully made in such a manner as to insure a thorough and continuous bond
West Prospect Ponds – Phase 1 02740-10 Flexible Pavement
10/05/04
between the old and new surfaces. The edge of the previously laid course shall be cut
back to its full depth so as to expose a fresh surface, after which the hot surface
mixture shall be placed in contact with it and raked to a proper depth and grade. Hot
smoothers or tampers shall be carefully used in such a manner as to heat up the old
pavement sufficiently (without burning it) to insure a proper bond. Before placing
mixture against them, all contact surfaces of curbs, gutters, headers, manholes, etc.,
shall be painted with a thin uniform coating of cationic emulsified asphaltic cement.
E. Compaction of the Mixture: After spreading, the mixture shall be thoroughly and
uniformly compressed by a power-driven roller or rollers, weighing not less than 8
tons, as soon after being spread as it will bear the roller without undue displacement.
Delays in rolling freshly spread mixture will not be tolerated. Rolling shall start
longitudinally at the sides and shall proceed toward the center of the pavement
overlapping on successive trips by at least ½ the width of a rear wheel. Alternate
trips of the roller shall be of slightly different lengths. If the width of the pavement
permits, it shall, in addition, be rolled at right angles to the center line.
The speed of the roller shall not exceed 3 miles per hour and shall, at all times, be
slow enough to avoid displacements of the hot mixture, and any displacement
occurring as a result of reversing the direction of the roller, or from any other cause,
shall at once be corrected by the use of rakes and of fresh mixture where required.
Rolling shall proceed continuously until all roller marks are eliminated. To prevent
adhesion of the mixture to the roller, the wheels shall be kept properly moistened, but
excess water will not be permitted.
The rollers shall be in good condition, capable of reversing without back-lash and
shall weight not less than 200 pounds to the inch of tread. They shall be operated by
competent and experienced rollermen and must be kept in continuous operation as
nearly as practicable in such a manner that all parts of the pavements shall receive
substantially equal compression.
Along curbs, headers, manholes, and similar structures, and all places not accessible
to the roller, thorough compactions must be secured by means of hot tampers and at
all contacts of this character, the joints between these structures and the surface
mixture must be effectively sealed.
The course, after final compaction, shall conform to the following requirements:
It shall be smooth and true to the established crown and grade. It shall have the
average thickness specified and shall at no point vary more than ¼-inch from the
thickness required by the OWNER or the Contract Documents. Any low or defective
places shall immediately be remedied by cutting out the course at such spots and
replacing it with fresh, hot mixture which shall be immediately compacted to
conform with the surrounding area and shall be free from depressions exceeding ¼-
inch as measured with a 10-foot straightedge paralleling the centerline of the
roadway.
After final compaction, the finished surface course shall at no point have a density
less than 95% of the maximum density possible to be obtained in a voidless
pavement composed of the same materials in like proportions. Density shall be
determined from specimens cut from the finished pavement as directed by the
ENGINEER.

3.04 ASPHALT PATCHING
A. Grading SG shall be placed in the bottom of the patches and shall be left one and
one-half (1/2) to two (2) inches below the existing street surface to allow the patch to
be "topped" with a surface course material. The "topping" material shall be Hot
Bituminous Pavement Grading SX for residential streets, and Grading S for arterials
and collectors. Hot Bituminous Pavement used for "topping" material will be
measured and paid for at the Contract Unit Price for Patching.
In locations where concrete repairs take place in an area of a large patch or in grind
areas and the grind operation does not immediately follow the concrete repair (three
(3) days), the CONTRACTOR shall remove no more than six (6) inches of pavement.
The pavement areas shall be temporarily patched with a minimum of two (2) inches
of asphalt.
Regardless of the delivery temperature, the mixture shall not be placed for use on the
roadway at a temperature lower than 225OF.
3.05 PAVING FABRIC
