plat. The Village Board may allow extensions for development of land
by sections or planned unit developments provided that the preliminary
plat is for a large area and the final plat applies to a portion
thereof.

changes or revisions as are deemed necessary in the interest and
needs of the community.
Subsequent approval will be required of the engineering proposals,

to be developed in units, not all at one time, and such plan for
developing in units has been approved by the Board of Trustees, the
final plat may be for one or more such units, and said tentative
approval of the preliminary plat covering the entire subdivision
shall remain effective for a period of five years after such approval.
Thereafter, said approval may be revoked by resolution of the Board
of Trustees.

B. Grading and Subgrade Preparation
1. Scope. The work covered by this section of the specifications
consists in furnishing all labor, equipment, supplies and materials,
and in performing all operations in connection with the excavations,
construction of embankments, including borrow and grading pertaining
thereto for streets, and the preparation of subgrade, as required,
complete, in strict accordance with this section of the specifications
and the applicable drawings.
2. Excavation. Excavation of every description and of whatever
substances encountered within the limits of the project shall be per-
formed to the lines and grades indicated on the drawings, except as
otherwise permitted by the Engineer, all excavated areas shall be
excavated in such a manner as will afford adequate drainage. All
suitable material removed from the excavations shall be used, insofar
as practicable, in the formation of embankments, backfilling, and for
such other purposes as directed by the Engineer. Where material
Subdivision Spectications Page 5.
encountered within the limits of the work is considered unsuitable and
any surplus of excavated material which is not required for embank-
ments shall be disposed of by the contractor.
3. Embankment. This work shall consist of the construction of
embankments by depositing, placing and compacting materials of
acceptable quality above the natural ground or other surface in
accordance with the lines, grades and cross - sections shown on the
plans, and as required by the Engineer.
Before any embankment is placed all clearing, tree removal, sod and
topsoil over the entire area shall be performed as directed by the
Engineer.
Clearing shall consist of the removal and disposal of all obstruc-
tions such as foundations, walls, fences, buildings, rubbish, etc.,
to a depth of at least twelve inches below subgrade elevation.
Sod within the area shall be removed to a depth of six inches.
Trees except those designated to be saved and all stumps shall be
removed to a depth of at least eighteen inches below the subgrade
elevation. All trees designated to be saved shall be protected care-
fully during clearing and subsequent construction operations.
Topsoil shall be excavated and stockpiled as directed by the
Engineer.
Each layer of the embankment material not to exceed eight inches
in loose depth shall be disked sufficiently to break down oversized
clods, thoroughly mix the different materials, secure a uniform
moisture content and insure uniform density and proper compaction.
Each layer shall be thoroughly compacted by roller or vibratory
equipment suitable for the type of embankment material.
4. Borrow or Excess Excavation. In the event sufficient suitable
filling material is not obtained within the limits of this contract to
provide all the embankment required, the contractor shall furnish such
additional filling material borrow to complete the designated
embankment.
All borrow shall be of the same type of soil as the embankment
material and shall be approved by the Engineer before being placed.
5. Subgrade. The bottom of the excavation for the pavement or top
of the fill shall be known as the pavement subgrade and shall conform
to the lines, grade and cross - sections shown on the plans.
All soft and yielding material and other portions of the subgrade
which will not compact readily when rolled or tamped shall be removed
as directed and replaced with suitable material placed and compacted
as specified herein.
The subgrade shall have uniform density and be compacted at or
slightly above the optimum moisture content. In the absence of
Subdivision Specifications
Page 6.
standard testing, a reasonable evaluation of moisture content may be
made by squeezing a ball of damp soil in the hand. If the ball is so
dry that it crumbles easily, additional water should be mixed into the
soil. If it is so wet that free water comes to the surface when
kneaded, the subgrade should be permitted to air out before final
rolling. The subgrade shall be thoroughly compacted with suitable
equipment.
All sewer trenches and structure excavations shall be backfilled to
natural or finished grade as soon as conditions permit. All backfill
shall be compacted with mechanical tampers in layers of not over six
inches loose material. Vibratory compactors that are small enough to
operate within the limited area are very satisfactory.
The subgrade shall be finished in
least one day's progress in advance
all times.
Concrete shall not be placed upon
or other subgrade, the stability of
Engineer, unsuitable for the placemi
an acceptable condition for at
of the pavement construction at
a soft, spongy or frozen subgrade
which is, in the opinion of the
Dnt of concrete.
The subgrade shall be in a moist condition at the time the concrete
is :placed. It shall be thoroughly wetted a sufficient time in
advance of the placing of the concrete to insure that there will be no
puddles or pockets of mud when the concrete is placed but shall not be
allowed to dry out before the concrete is placed.
Immediately prior to placing the concrete, the subgrade shall be
tested for conformity with the cross - section shown on the plans by
means of an approved template riding on the side forms. If necessary,
material shall be removed or added, as required, to bring all portions
of the subgrade to the correct elevation. It shall then be thoroughly
compacted and again tested with the template. Concrete shall not be
placed on any portion of the subgrade which has not been tested for
correct - elevation. The subgrade should also be cleared of any loose
material which may have fallen upon it.
6. Protection of Subgrade. The finished subgrade shall be main-
tained in a smooth and compacted condition until the concrete has
been placed.
The mixer, ready -mix trucks, or other equipment shall not operate
between the forms in the paving lane unless conditions of the job will
not permit operation from the shoulder or outside the lane. Mixer or
ready -mix trucks shall not be permitted to operate from previously
paved lanes until the pavement is at least seven days old or a flex-
ural strength of 550 psi is attained with AASHO Standard Method T 23
and T 97.
If it is necessary to operate trucks between the forms and they
cause rutting or displacement of the subgrade material, either lighter
trucks shall be used or suitable runways shall be provided. The
contractor shall re -roll or hand -tamp the subgrade to correct any ruts
or other objectionable irregularities which may have been caused by
the trucking of materials.
Subdivision Specifications Page 7.
A berm shall be graded between the curb and sidewalk, or property
line.where there are no existing sidewalks, in a neat, workmanlike
manner. All excess concrete and debris shall be removed from the
excavation behind the curb line before backfilling.

5. Job Mixed Concrete. Job mixed concrete shall be mixed in a drum
mixer which shall conform to the concrete paving mixer standards of
the Mixer Manufacturers Bureau of the Associated General Contractors
of America. The mixer shall be capable of combining the aggregates,
cement and water into a thoroughly mixed and uniform mass within the
specified time, and of discharging the material without segregation.
The entire contents of the drum shall be discharged before recharging.
The volume of the mixed materials per batch shall not exceed the man-
ufacturer's guaranteed capacity (110 per cent of rated capacity) of
the mixer.

Ready -Mixed Concrete (Designation C -94). Any concrete which is not
plastic and workable when it reaches the subgrade shall be rejected.
When construction conditions are such that it is absolutely
necessary for trucks hauling concrete to operate on the grade between
forms they shall not back over previously deposited concrete.
8. Remixing. Concrete or mortar that has stiffened but not set may
be used after remixing if it is plastic enough to be compacted in the
forms. Water must not be added at time of remixing.
9. Measuring Air Content. The air content of freshly mixed air -
entrained concrete shall be checked at least twice daily. Concrete
with air contents above or below the amount specified in Paragraph E2
shall be corrected by adjustments in the mix design or quantities of
air - entraining admisture being used.

be straight, free from bends or warps.
The maximum deviation of the top surface of any section shall not
exceed one - eighth inch, or the inside face not more than one - fourth
inch from a straight line. The method of connection between sections
shall be such that the joint thus formed shall be free from movement
in any direction. Forms shall be of such cross - section and strength
and so secured as to resist the pressure of the concrete when placed,
and the impact and vibration of any equipment which they support,
without springing or settlement.
Each ten foot length of form shall have at least three form braces
and pin sockets which shall be spaced at intervals of not more than
five feet, having the end brace and socket not more than six inches
from the end of the form. Approved flexible forms shall be used for
construction where the radius is 150 feet or less.

2. Grade and Alignment. The alignment and grade elevations of the
forms shall be checked by the contractor's engineer and the necessary
corrections made by the contractor immediately before placing the
concrete. When any form has been disturbed or any subgrade thereunder
has become unstable, the form shall be reset and rechecked.
3. Placing Concrete. The concrete shall be mixed in quantities
required for immediate use and shall be deposited on the subgrade to
the required depth and width of the construction lane in successive
batches and in a continuous operation without the use of intermediate
forms or bulkheads. The concrete shall be placed as uniformly as
possible in order to minimize the amount of additional spreading
necessary. While being placed, the concrete shall be spaded or
vibrated and compacted with suitable tools so that'the formation of
voids or honeycomb pockets is prevented. The concrete shall be
especially well spaded or vibrated and temped against the forms and
along all joints. Care shall be taken in the distribution of the
concrete to deposit a sufficient volume along the outside form lines
so that the curb section can be consolidated and finished simultan-
eously with the slab.
No concrete shall be placed around manholes or other structures
until they have been brought to the required grade and alignment.
- Subdivision Specifications Page 12.
4. Cold Weather Concreting. Except by specific written authoriza-
tion concreting shall cease when the descending air temperature in
the shade and away from artificial heat falls below 400 F. It shall
not be resumed until the ascending air temperature in the shade and
away from artificial heat rises to 350 F.
H. Consolidating and Finishing.
1. General. The pavement shall be struck off and consolidated
with a mechanical finishing machine or by hand - finishing methods.
When a mechanical finishing machine is used, the concrete shall be
struck off at such a height that after consolidation and final finish-
ing it shall be at the exact elevation as shown on the plans. A depth
of at least two inches of concrete shall be carried in front of the
strike -off screed for the full width of the slab, whenever the screed
is being used to strike off the pavement. The finishing machine shall
be provided with a screed which will consolidate the concrete by
pressure. The concrete shall, through the use of this machine, be
brought to a true and even surface, free from rock pockets, with the
fewest possible number of sages of the machine. The edge of the
screeds along the curb line may be notched out to allow for sufficient
concrete to form the integral curb. Hand - finishing tools shall be
kept available for use in case the finishing machine breaks down.
When hand - finishing is used, the pavement shall be struck off and
consolidated by a vibrating screed to the exact elevation as shown on
the plans. When the forward motion of the vibrating screed is stopped
the vibrator shall be shut off, it shall not be allowed to idle on
the concrete.
2. Longitudinal Floating. After the concrete has been struck off
and consolidated it shall be further smoothed by means of a longitudi-
nal float. If a mechanical longitudinal float is not used a longitud-
inal hand float shall be operated from foot bridges spanning the pave-
ment and shall be worked with a wiping motion, parallel to the pave-
ment centerline, and passing from one side of the pavement to the
other. Movement ahead along the centerline of the pavement shall be
in successive advances of not more than one half of the length of the
float. The float shall be not less than twelve feet in length and six
inches in width and shall be properly stiffened and provided with
handles at each end.
3. Scraping. After the passage of the longitudinal float, the
pavement shall be scraped with a straightedge 10 feet long, equipped
with a handle to permit it to be operated from the edge of the pave-
ment. The straightedge shall be operated so that any excess water and
laitance are removed from the surface of the pavement.
4. Straightedging. After the longitudinal floating and scraping
have been completed and any excess water removed, but while the con-
crete is still plastic, the slab surface shall be tested for smooth-
ness with a ten foot straightedge swumg from handles three feet
longer than one -half the width of the slab. The straightedge shall
be placed on the surface parallel to the centerline of the pavement
..Subdivision Specifications ' Page 13.
and at not more than five -foot intervals transversely. After each
test the straightedge shall be moved forward one -half its length and
the operation repeated. When irregularities are discovered they shall
be corrected by adding or removing concrete. All disturbed places
shall be floated with a wooden float not less than three feet long and
not less than six inches wide, and again straightedged. The pavement
surface shall have no depression in which water will stand.
The use of the long- handled wood floats shall be confined to a
minimum. They may be used behind the longitudinal float to correct
surface unevenness not taken care of by the longitudinal float, but
shall not be used to float the entire surface of the pavement in lieu
of or supplementing the use of the longitudinal float.
5. Edging. Before the final finishing is completed and before the
concrete has taken its initial set, the edges of the slab and curb
shall be carefully finished with an edger of the radius shown on the
plans.
6. Final Surface Finish. A burlap drag shall be used as the final
finishing method. The drag shall be at least three feet in width and
long enough to cover the entire pavement width. It shall be kept
clean and saturated while in use. It shall be laid on the surface of
the pavement and dragged forward in the direction in which the pavement
is being laid. The curb shall have the same final finish as the
pavement.
The final surface of the concrete pavement and curb shall have a
uniform gritty texture free from excessive harshness and true to the
grades in the final finishing procedure as required to produce the
desired final surface texture.
2. Integral Curb.
Integral curbs shall be required along the edges of all street pave-
ment as indicated on the plans, except at such locations as the
engineer may direct. Depressed curbs shall be provided at all drive-
way entrances and at such other locations as designated by the
engineer.
The integral curb shall be constructed immediately following the
finishing operation. Special care shall be taken so that the curb
construction does not lag the pavement construction and form a "cold
joint ".
Steel curb forms shall be required to form the backs of all curbs
except where street returns of small radius or other special sections
make the use of steel forms impractical.
In placing concrete curb, sufficient spading shall be done to
secure adequate bond with the paving slab and eliminate all voids in
the curb.
Curbs shall be formed to the cross - section as shown on the drawings
with a mule or templates supported on the side forms and a wood float
not less than four feet in length.
..Subdivision Specifications Page 14.
The finished surface of the curb and gutter shall be checked with
the use of the ten feet straightedge and corrected if necessary.
While the concrete is still plastic the drainage at the gutter should
be- checked by pouring water at the gutter summit and observing its
flow to the inlet. In order to prevent damage to the concrete surface
water should be poured onto a piece of burlap or curing paper.
J. Curing.
Concrete shall be cured by protecting it against loss of moisture,
rapid temperature change, and from rain, flowing water, and mechanical
injury for a period of not less than five days from the beginning of
the curing operation. Moist curing, waterproof paper, white polyethy-
lene sheeting, liquid membrane compound or a combination thereof may
be used for curing. Immediately after finishing operations have been
completed, the entire surface of the newly laid concrete shall be
covered by the curing medium which is applicable to local conditions
and approved by the engineer. The edge of concrete slabs exposed by
the removal of forms shall be protected immediately to provide these
surfaces with continuous curing treatment equal to the method selected
for curing the slab surface and to prevent injury to pavement edges.
The use of a covering material which contains or becomes contaminat-
ed with sugar in any form, tannic acid, or any other substance con-
sidered detrimental to Portland cement will not be permitted. The
initial curing medium shall be effective and shall be applied so as to
prevent checking, cracking, and the appearance of dry spots in the
surface of the concrete. The contractor shall have the equipment
needed for adequate curing at hand and ready to install before actual
concrete placement begins. In all cases in which the curing medium
requires the use of water, the curing shall have prior right to all
water supply. Failure to provide sufficient cover material of the
type selected, failure to maintain saturation for the entire curing
period in the moist - curing methods, lack of water to adequately care
for both curing and other requirements, or other failures to comply
with curing requirements shall be cause for immediate suspension of
concreting operations.
1. Moist Curing. Moist curing shall be accomplished by covering of
burlap, cotton mats or other approved fabric mat, used singly or in
combination.
Curing mats shall be thoroughly wet when applied and kept continu-
ously wet and in intimate contact with the pavement surface for the
duration of the moist curing period. Other fabric mats shall conform
in design and shall provide a curing medium at least equal to cotton
mats. Cotton mats, other fabric mats, and burlap strips shall be
furnished in the widths or lengths, after shrinkage, required to cover
the entire width and edges of the pavement lane, mats or burlap shall
be lapped at joints between adjacent sheets to prevent drying of this
location. Moist curing when used as initial curing shall be continued
for not less than twenty -four hours.
2. Waterproof Paper Curing. The surface of the concrete shall be

immediately repaired.
3. White Polyethylene Sheeting. White polyethylene sheeting shall
meet the specifications under Paragraph D13 and the following
provisions of this paragraph.
4. Liquid Membrane Curing Compound. Pigmented liquid membrane
curing compound shall meet the specifications under Paragraph D13. The
curing compound must be applied to cover the surface completely and
uniformly at a rate which will achieve the performance requirement
specified in AASHO Specifications M -148. This method of curing shall
be applied immediately behind the final finishing operation or after
the initial curing when a combination of methods are used. Failure
to provide complete and uniform coverage at the required rate will be
cause for discontinuance of this method of- curing and the substitution
of one of the other approved methods. The compound shall be kept
agitated to prevent the pigment from settling. Special care shall be
taken to apply the curing compound to the pavement edges immediately
after the forms have been removed.
K. Joints. Longitudinal and transverse joints shall be constructed
as shown on the plans.
Longitudinal joints are those points parallel to the lane of con-
struction. They may be either intermediate center joints or the
construction joints between construction lanes.

held accurately in place during the placing and finishing of the con -
crete by a bulkhead, a metal channel cap or other approved method.
Under no circumstances shall any concrete be left above the expan-
sion material or across the joint at any point. Any concrete spanning
the ends of the joint next to the forms shall be carefully cut away
after the forms are removed.
Before the pavement is opened to traffic the groove above the filler
shall be cleaned and sealed with specified joint sealing material
covered under Paragraph D9.
3. Transverse Contraction Joints. Transverse contraction joints
shall be of the sawed, formed dummy groove or premolded strip type.
4. Transverse Sawed Contraction Joints. When transverse contrac-
tion joints are to be formed by sawing, care must be taken to saw the
grooves soon after placing to prevent the formation of cracks due to
contraction of the slab. All transverse joints shall be sawed at
least 1/4 of the slab depth. Any procedure for sawing joints that
results in premature and uncontrolled cracking shall be revised
immediately by adjusting the time interval between the placing of the
concrete and the cutting of the joints.
5. Transverse Formed Dummy Groove Joints. Transverse dummy
groove joints shall be formed by a groove or cleft in the top of the
slab of the dimensions shown on the plans. The groove made in the
plastic concrete by a suitable tooling device, shall extend vertically
downward 1/4 of the slab depth from the surface and shall be true to
line.
6. Transverse Premolded Strip Joints. Transverse premolded strip
shall be of the proper dimensions as shown on the plans. The premold-
ed filler is placed in a vertical groove formed to receive it. The
top of the filler should be flush with the pavement surface.
7. Transverse Construction Joints. Transverse construction joints
of the type shown on the plans shall be placed wherever the placing of
concrete is suspended for more than thirty minutes. A butt type joint
with dowels shall be used if the joint occurs at the location of a
contraction joint. Keyed joints with tiebars are used if the joint
occurs at any other location.
8. Dowels. If joints are to be equipped with dowels they shall be
of the dimension and at the spacing and location indicated on the
plans. They shall be firmly supported in place, accurately aligned
parallel to the pavement grade and the centerline of the pavement by
means of a dowel support which will remain in the pavement and will
insure that the dowels are not displaced during construction. One -
half of each dowel shall be painted and greased and in expansion
joints one end shall be equipped with a tight fitting sleeve of the
dimensions shown on the plans conforming to Paragraph D12.
Subdivision Specifications
Page 17.

shown on the plans. They shall be of the sawed, dummy groove pre -
molded strip, or the keyed construction type. Joints between con-
struction lanes shall be the keyed construction type.
10. Longitudinal Center Joint. Longitudinal center joints shall
be of the sawed, formed dummy groove or premolded strip type.
11. Sawed Longitudinal Center Joints. Sawed longitudinal center
joints shall be sawed grooves made with a concrete saw after the
concrete has hardened. The saw cut shall be at least 1/4 of the slab
depth. The joint may be sawed at any time prior to the time the pave-
ment is open to traffic. These joints are otherwise formed in the
same manner as the transverse sawed joints - Paragraph K4.
12. Longitudinal Formed Dummy Groove Joints. Longitudinal dummy
groove joints are formed in the same manner described for Transverse
Formed Dummy Groove Joints, Paragraph K5.
13. Longitudinal Premolded Strip Joint. Longitudinal premolded
strip joints are formed in the same manner described for Transverse
Premolded Strip Joints, Paragraph K6.
14. Longitudinal Construction Joints. Longitudinal construction
joints (i.e., joints between construction lanes) shall be of the
dimensions shown on the plans. The key shall be constructed by
placing a deformed metal plate against the form when the first lane
adjacent to the joint is placed. This metal plate shall be removed
with the form. When placing the second slab, care must be taken that
no concrete is left to overhang the lip formed in the first slab by
the edging tool.
15. Tiebars. Tiebars or tiebolts when shown on the plans shall be
of deformed steel and of the dimensions and at the spacing specified.
Tiebars shall be firmly supported by subgrade chairs or so installed
as not to be displaced during construction operations.
16. Joint Sealer. After the curing period all sawed and dummy
groove joints in the pavement shall be cleaned and sealed with mater-
ial meeting the requirements of Paragraph D9. All foreign material,
joint sawing residue, dirt and curing membrane shall be removed.
Joints shall be slightly under- filled (about 1/4 inch) to prevent
extrusion of sealer. Any excess material should be removed from the
pavement surface as soon after sealing as possible.
17. Integral Curb Joints. In the construction of transverse joints
of concrete integral curb pavement, special care must be taken to see
that all transverse points extend continuously through the pavement
and curb.
L. Structures. All manholes, catch basins, or structures of a
permanent nature encountered in the areas to be paved shall be raised
or lowered as the case may be, to the surface of the new pavement and
the necessary expansion material as specified in Par. D8 placed around
each structure for the full depth of the slab and of the thickness

Subdivision Specifications
Page 18.
M. Cold Weather Protection. When concrete is being placed in cold
weather and temperature may be expected to drop below 35 °F. a supply
of straw, hay, insulated curing blankets or other suitable material
shall be provided along the line of the work. Membrane cured pave-
ment shall be protected with waterproof paper if straw is to be placed
soon after the pour to prevent straw from embedding in surface. At
any time when the air temperature may be expected to reach the freez-
ing point during the day or night, the material so provided shall be
spread over the concrete to a sufficient depth to prevent freezing of
the concrete. Concrete shall be protected from freezing temperatures
until it is at least five days old. Concrete injured by frost action
shall be removed and replaced at the contractor's expense.
N. Protection and Opening to Traffic. The contractor shall pro-
tect the pavement against all damage prior to final acceptance of the
work by the owner. Traffic shall be excluded from the pavement by
erecting and maintaining barricades and signs until the concrete is
at least seven days old, or for a longer period if so directed by the
engineer.- The pavement shall not be used at any time within this
period for transporting of operating equipment. As a construction
expedient, the subgrade planer, concrete finishing machine, and
similar equipment may be permitted to ride upon the edges of pre-
viously constructed slabs provided the concrete is more than seventy -
two hours old, and the equipment has rubber -tired wheels to run on
the finished slab.
Further provided that two coats of boiled linseed oil mixture be
applied to concrete pavement constructed after September 15th which
would be opened to traffic prior to the following April 15th to
minimize spalling from salt action.
0. Optional Construction Equipment.
1. Slip -form Paver. In lieu of the construction methods described
in the preceding section of the specifications, the contractor may use
a slip -form paver. When the slip -form paver is used, all reference
in the preceding sections of this specification referring to forms
shall be deleted.
Slip -form pavers shall be equipped with vibratory and tamping bar
assemblies which are effective over the full width of the pavement.
The paver shall also have a metal float with a bullnozed front end
for the full width of the pavement, excluding curbs, which will
extrude the concrete under pressure.
Behind the float shall be a rubber belt, mechanically operated and
with a lateral movement of 4 to 8 inches. The curb shall be formed
by extrusion plates or mules mounted at the rear of the machine. The
requirement for longitudinal floating (Par. H2) shall be deleted.
2. Subgrade. The subgrade shall be brought to the proper grade
and cross - section by means of a properly designated and operated
machine. The subgrade shall comply with applicable sections of this
specification. If any traffic is allowed to use the prepared sub-
grade, some device, satisfactory to the engineer, shall be provided
Subdivision Speclications '
Page 19.
for checking and correcting the subgrade immediately ahead of placing
the concrete. The subgrade work, especially the path on which the
tracks of the paver ride, must be done carefully and accurately as its
degree of precision greatly affects the resulting smoothness of the
pavement surface.
3. Placing. Concrete shall be uniform slump and adequately supp-
lied in front of the paver. The rate of progress shall be controlled
so that the forward movement of the paver will be as nearly continuous
as practicable. If it is necessary to stop the forward movement of
the paver the vibrator and tamping elements shall also be stopped
immediately. Care must be taken to see that a sufficient supply of
concrete passes around the float and the belt along the form line to
form the integral curb where shown on the plans.
4. Final Finishing and Testing. Final finishing operations shall
conform to the applicable sections of this specification. Strength
and testing requirements to be in accordance with Section 408 of the
Standard Specifications.
5. Driveway Approaches - Other than Residential or Dwelling.

constructed of Portland cement concrete at least six inches in thick-
ness. Concrete driveway approaches shall be in compliance with the
methods and materials required in the preceding paragraphs of this
section.
Residential and Dwelling. Driveway approaches for residential or
dwelling use shall be constructed in a manner and of a material equal
at least to that existing for the paving in the public street adjacent
thereto. If a concrete pavement exists for the paving in the public
street, the owner may, upon written request, install a base of water
bound macadam at least six inches thick and a black top surface of
two inches, or may be constructed of Portland cement concrete in
accordance with methods and materials required in Section 623, Stand-
ard Specifications for Road and Bridge Construction, Division of
Highways, State of Illinois, adopted January 2, 1971, as revised.
Sidewalk Space. Where a driveway is constructed across the sidewalk
space, it shall conform to the sidewalk grade as established by the
Village. Where a driveway of any kind of material is constructed
across an existing sidewalk, said sidewalk shall be removed and
replaced with Portland Cement Concrete for the full width of the
driveway and for a distance of at least the width of said sidewalk,
or a width as established by the Board of Trustees, and to a minimum
thickness of six inches.

other types of driveway approaches permitted herein shall be not less
than six inches thick, compacted depth.
Concrete Street. Where paving in the public street is of concrete,
and a concrete driveway approach is constructed, a one inch bituminous
premoulded expansion joint with load transmission unit shall be
Subdivision Specifications Page 20.
placed approximately three feet from the edge of the said concrete
paving and normal to the center line of the driveway, in accordance
with sketches illustrating such construction on file with the
Village Engineer.
Spacing of Driveway Approaches. Where two or more adjoining
driveways are provided for the same property, a safety island measur-
ing not less than ten feet at the outer or street edge, shall be
provided between driveways. Not more than two such driveways shall
be allowed to any one street for each one hundred feet of continuous
frontage thereof.
Curb Line. The width of the driveway opening at the curb line
shall not exceed the width of the driveway at the inner or property
edge plus twenty feet, not be less than the width of the driveway at
the inner or property edge of the sidewalk plus ten feet. In no
instance shall the radius be less than three feet at curb corners, and
this only when the driveway is flared; or more than ten feet when the
driveway edge is at right angles to the street line. The center line
of all driveways must be approximately at right angles to the curb
line of the pavement in the public street for a distance of at least
ten feet from said curb line.
Grade. All driveways shall be so graded between the gutter and the
sidewalk that it will not be necessary to change the established
grade of either and will not elevate or depress any portion of either.
No part of said driveway shall extend beyond the curb line in such a
manner as to change the grade of said gutter or obstruct the free
flow of water in said gutter. Where elevations or depressions are
necessary in the parkway strip between the curb and walk, said park-
way shall be graded on both sides of the driveway to a distance
sufficient to create a gradual ascent or descent. At no time shall
the gradient exceed one foot vertical to ten feet horizontal.
Curb and Gutter. Combined curb and gutter and separate curbing
shall be entirely removed for the full width of the driveway opening
at the curb line. If an existing joint in said curb is within five
feet of the end of the driveway opening, the existing curbing, etc.,
shall be removed to said joint, otherwise said combined curb and
gutter or separate curbing shall be cut, making a neat edge at right
angles to the edge of the pavement and vertical. Integral curbing,
which is that type placed with the "V" pavement and moulded as an
integral part of it, must be removed for the full depth from the top
of the curb to the bottom of the pavement. The edge shall be cut as
above described. No combined curb and gutter, straight curb or
integral curb shall be removed within five feet of a public cross walk.
Ditches. Where driveway approaches cross open ditches in the park-
way, culverts shall be installed. Said culverts shall be of such size
and shall be constructed of such material as determined by the Dept.
of Public Works, depending on the conditions existing. In no instance
shall the size of the opening be less than that obtained by a twelve
inch diameter pipe. The length of culvert shall be determined by the
following method: For ditch depth of two feet or less the culvert
Subdivision Specifications
Page 21.
shall extend not less than five feet beyond both edges of the driveway
where it crosses the ditch. For each additional foot depth of ditch,
add two feet to the above figures, except that no culvert shall be less
than twenty feet long, and except that where headwalls are constructed
at the ends of the culvert the length shall be as determined by the
Department of Public V,, orks .
Meter Pits. Where existing meter pits are in the area of the pro_
posed driveway, the existing cast iron top shall be removed and turned
in to the Water Department and the additional cost thereof shall be
paid by the contractor or owner.
Catch Basins, All driveway approaches constructed or reconstructed
over, across or upon any public street or public parkway in the Vill-
age shall be kept and maintained in accordance with the provisions
hereof by the person so constructing, reconstructing or using the same
as adjunct or apljurtena.nce to lands or proderites immediately adjacent
thereto.

or mortar, including water, shall be one which will insure separate
and uniform proportions of each of the materials at all times.
2 Proportions: The concrete shall be mixed in the proportions
which, when the proaer amount of water is added, will produce a mini-
mum compressive strength of eighteen hundred pounds per square inch
after seven days and a minimum compressive strength of three thousand
pounds per square inch after twenty- -eight days when curOd under field
conditions..
3. Admixtures: Air Entraining Admixtures shall not be added to

If such approval is granted, the admixture shall conform to Section 11 --
and shall be added in the amount and in the manner prescribed by the
manufacturer so that the air content of the concrete shall not be less
than three nor more than six percent,
IV. MIXING:
1. Method: All concrete shall be mixed in a stationary batch
mixer or truck mixer unless manual mixing is authorized by the
en=; ine er. .
(a) If a stationary batch mixer is used the mixer drum shall be
of adequate size to accommodate the maximum batch and shall conform
to the Concrete Mixer Standards adopted by the Mixer 14anufacturers
Bureau of the Associated General Contractors of America. The mixer
drum shall be rotated at the rate specified by its manufacturer. When
a stationary batch mixer is used for complete mixing, the minimum
mixing time for mixers of one cubic yard capacity or less shall be one
minute; for larger capacities of mixtures the mixing time shall be
increased at the rate of one - quarter minute for each additional cubic
yard or fraction thereof.
The mixing time shall begin when the correct proportions of cement
and aggregates are placed in the mixer.. A portion of the water shall
be placed in the mixer in advance of the cement and aggregates. The
full amount of water required to produce a mix of the consistency
herein specified, shall be added to the cement and aggregates before
one quarter of the mixing time has elapsed. The size of the batch
shall not exceed the maximum rated capacity as specified by the manu-
facturer of the mixer. The drum shall be completely emptied before
receiving material for the succeeding batch,
Subdivision.Specifications
Page 23
(b) Truck mixers if used, shall be of the revolving drum type.
When a truck mixer is used for mixing the concrete, the drum shall be
rotated at mixing speed for not less than fifty nor more than one -
hundred revolutions after all of the ingredients of each batch are -
placed in the drum. When a truck mixer is used for the complete mix-
ing of the concrete, the mixing operation shall begin within thirty
minutes after the cement has been intermingled with the aggregates.
The size of the batch shall not exceed the manufacturer's rated capa-
city as shown on a metal rating plate which shall be attached in a
prominent place on the truck mixer. The drum shall be completely
emptied before receiving material for the succeeding batch.
(c) The mixing time at stationary batch mixers may be reduced to
the minimum required (about thirty seconds) to intermingle the in-
gredients when truck mixtures are used to deliver the mix to the site
of the work. When this practice is followed each batch shall be
thoroughly mixed in the truck mixer by rotating the drum at mixing
speed for not less than fifty nor more than one hundred revolutions.
(d) If manual mixing is authorized by the engineer, the cement and
aggregates shall be mixed dry on a water tight platform until the
mixture is of uniform color. The full amount of water required shall
then be added and the mixing continued until the mass is of the con-
sistency herein specified.
2. Consistency: The aggregates, cement and water shall be
thoroughly mixed in accordance with these specifications to produce
a homogenous mass which can be deposited in the forms without separa-
tion. The consistency of the mix shall be such that the slump shall
not exceed three inches.
3. Delivery; Concrete shall be delivered to the site of the work
with a satisfactory degree of uniformity at the consistency specified
and shall be hauled in a water tight container in which segregation
will not take place and from which the concrete can be discharged
freely.
(a) Concrete shall be delivered to the site of the work and
discharged from the hauling container within a period of ninety
minutes after the introduction of the mixing water to the dry materi-
als unless otherwise specified by the engineer.
(b) Slump tests of individual samples taken at approximately the
one - quarter and three - quarters points of the load during discharge
shall not differ by more than two inches.
4. Retemperingr The retempering of mortar or concrete which has

prohibited.
Subdivision Specifications Page 24
V. FOUNDATION:
1. Sub - grade: The finished sub -grade shall have a transverse slope
of not more than one -half inch per foot and shall be prepared as
follows:
(a) All soft and spongy places shall be removed and all depressions
filled with suitable material which shall be thoroughly compacted in
layers not exceeding six inches in thickness.
(b) When the concrete sidewalk is to be constructed over an old
path composed of gravel or cinders, the old path shall be entirely
loosened, the material spread for the full width of the sub -grade
and thoroughly compacted.
(c) All fills shall be made in a manner satisfactory to the
engineer. The use of muck, quicksand, soft clay, spongy or perishable
material is prohibited. The top of all fills shall extend beyond
the walk on each side for at least one-foot, and the sides shall have
a slope of at least one or one and one -half to one.
2. Drainage: Suitable drainage systems shall be installed and
connected with sewers or other drains as indicated on the plans.
3. Sub -base: A sub -base may be required by the engineer, if, in
his opinion, the soil in the sub -grade will swell or shrink with
changes in its moisture content to such an extent that the concrete
may be damaged. If a sub -base is required, it shall consist of
material as hereinbefore specified, and shall be spread to a depth
of at least four inches, and thoroughly compacted. When a sub -base
is spread on fills, the side slope of the sub -base shall be the same
as the side slope of the fill. While compacting the sub -base the
material shall be thoroughly wet, and shall be wet when the concrete
is deposited but shall show no pools of water.
VI`.. DIMENSIONS:
1. Size of slabs: The slabs shall have an area of not more than
one hundred square feet. Length of slab shall be equal to the width.
2. Thickness of Walk: Minimum thickness shall be four inches. At
driveway openings to dwellings, the minimum thickness of the walk
shall not be less than six inches. The minimum thickness of driveway
openings to alleys and commercial and industrial establishments shall
be not less than eight inches.
VII. FOEMS:
1. Materials: Forms shall be free from warp and of sufficient
strength to resist springing out of shape. All wood forms shall be
thoroughly wetted and metal forms oiled or coated with soft soap or
whitewash before depositing any material against them. All mortar and
dirt shall be removed from the forms that have been previously used.
Subdivision Specifications Page 25
2. Setting: The forms shall be well staked or otherwise held to
the established lines and grades and their upper edges shall conform
to the established grade of the walk and shall be so aligned as to
provide a transverse slope toward the curb of one - quarter inch per
foot unless otherwise directed by the engineer.
VIII. JOINTS:
1. Contraction Joints: Contraction joints shall be constructed
at right angles to the center line of the sidewalk; the grooves shall
extend to one - fourth the depth of the sidewalk. They shall not be
less than one - eighth inch or more than one - fourth inch in width and
shall be edged with an edging tool having a one - fourth inch radius.
No slab shall be longer than the width of the sidewalk nor less
than four feet unless otherwise directed by the Village Engineer.
IX. DEPOSITING CONCRETE:
1. Continuous Pouring: After mixing, the concrete shall be
handled rapidly and the successive batches deposited in a continuous
operation until individual sections are completed. Under no circum-
stances shall concrete that has partly hardened be used. The forms
shall be filled and the concrete brought to the established grade.
2. Cold Weather Pouring: Concrete shall not be deposited when it
appears likely that the air temperature may fall below 40 degrees F.
during the pouring or within the following 24 hours unless preparations
are made and precautions taken to prevent any damage to the concrete
resulting from the low temperature. When placing concrete in cold
weather, the contractor shall plan and prosecute his work in a
manner which will assure satisfactory results. Any concrete damaged
by freezing shall be removed and replaced by the contractor at his
own expense.
Concrete when deposited in the forms shall have a temperature of
not less than 55 degrees F. nor more than 100 degrees F. The
concrete shall be maintained at not less than the minimum temperature
of 55 degrees F. for at least seventy -two hours after placing, or
longer if necessary, until the concrete has thoroughly hardened.
Concrete shall not be deposited on a frozen foundation.
X. FINISHING:
1. Method: After the concrete has been brought to the established
grade by means of a strike - board, it shall be worked with a steel
trowel or wood float to give it a smooth, medium rough, or rough
surface, as directed by the engineer. In no case shall dry cement or
a mixture of dry cement and sand be sprinkled on the surface to absorb
moisture or to hasten hardening. The type of finished surface re-
quired by the engineer shall be prepared as follows:
(a) Smooth Surface: The surface of the concrete shall be troweled
with a steel trowel to a smooth, even surface free from depressions
or irregularities of any kind. Excessive working of the surface with
the trowel shall be avoided.
Subdivision Specifications Page 26
(b) Medium Rough Surface: The surface shall be floated with a
wooden float only, producing an even gritty finish. On wide sidewalks
the finishing may be done with two applications of a canvas belt, not
less than six inches wide, and two feet longer than the width of the
sidewalk. For the first application, the belt shall be drawn across
the surface with vigorous strokes at least twelve inches long, and
moved ahead very slightly with each stroke. The second application
shall be given immediately after the water glaze or sheen disappears.
The stroke of the belt shall be not more than four inches, but the
longitudinal motion shall be greater than during the first application.
(c) Rough Surface: The surface shall be floated with a wooden
float leveling all sags and producing an even surface. After being
floated in this manner the roughening shall be done by slapping the
surface of the concrete with the face of the float. The float shall
be raised vertically from the concrete after each stroke.
2. Edges: Unless protected by metal, the surface edges of all
slabs shall be rounded to a radius of one -half inch. The edges of
all slabs which act as curbing shall be rounded to a radius of one
and one -half inch.
3. Name Stamp: The contractor shall mark in the walk at each
end of every one hundred and fifty feet of walk or fraction thereof,
either by stamping or by inlaying an approved metal plate, his name
and year in which the walk is constructed. The stamped letters shall
be one inch high and one - fourth inch deep. If a metal plate is used,
the top of the plate shall be flush with the top of the walk.
XI. CURING AND PROTECTION:
1. Method: As soon as the concrete has hardened sufficiently
to prevent damage, the finished surface shall be sprinkled with
water or covered with sand or earth and, in either case, kept wet
for at least three days. When authorized by the engineer, a chemical
curing agent may be used, provided it is applied in accordance with
the manufacturer's specifications. When high early strength cement is
used, the minimum curing period shall be reduced to forty -eight hours.
The freshly finished surface shall be protected from hot sun and
drying winds until it can be sprinkled or covered as above specified.
The concrete surface must not be damaged or pitted by rain. The
contractor shall provide and use, when necessary, sufficient tarpau-
lins to completely cover all sections that have been placed within
the preceding twelve hours. The contractor shall erect and maintain
suitable barriers to protect the finished surface. Any section damag-
ed from traffic or other causes occurring prior to its official accep-
tance, shall be repaired or replaced by the contractor at his own ex-
pense in a manner satisfactory to the engineer. The covering shall
be removed and disposed of by the contractor and the sidewalk back -
filled to a minimum of one foot on each side before the work is
officially accepted by the engineer.
XII. TESTING:
1. The engineer may at his discretion, require the contractor to
submit representative samples of the materials he proposes to use
Subdivision Specifications Page 27.
prior to delivery of the materials to the site of the work, and may,
during the progress of construction, take samples and make tests to
assure that the work is being performed in accordance with these
specifications. The contractor shall co- operate in the making of
such tests to the extent of allowing free access to the work, for
the selection of samples.
2. All tests and samples shall be paid for by the contractor.
9.207 Alleys.) Where required, alleys shall be provided with a
right of way of twenty feet and a paved surface of sixteen feet.
This pavement shall be the equivalent of eight inches of gravel or
crushed stone and shall be held in place by metal or treated wood
curbs.
9.208 Pipeline Trench Construction.) The general conditions are a
part of this specification and the Contractor is to consult them for
instructions pertaining to the work under this heading.
Work Included: The work to be done under this specification shall
inc u e e furnishing of all implements, machinery, equipment,
materials, and labor necessary to excavate and backfill trenches for
water mains, storm sewers, sanitary sewers, force mains, and appurt-
enances, and to restore original ground surfaces.
Excavation: The trench shall be excavated so that the elevation
of the inis ed line will be at the depth and grade shown on the
plans with allowance for bedding as hereinafter specified. Unless
otherwise indicated, all water mains and force mains shall be laid
so that the minimum cover over the top of the pipe will be 5 feet.
The width of the trench at the top of the pipe shall not be greater
than 2.2 feet for 4 -inch through 12 -inch pipe, 3 feet for 14 -inch
through 18 -inch pipe, 32 feet for 20 -inch through 24 -inch pipe, 4 ft.
for 27 -inch and 30 -inch pipe and one and one -third times the outside
diameter of the pipe for sizes greater than 30 inches. In the event
that the Contractor varies or requests to vary from these limitations
the Engineer will determine the construction procedure and materials
which will be required of the Contractor to prevent overstressing
the pipe.
Where firm foundation is not encountered at the bottom of the
excavation, due to soft, spongy or other unsuitable soil, the Con-
tractor shall remove all such unstable material and replace as
required under BEDDING OF PIPE. All excavated material not needed on
the work shall be disposed of by the Contractor at locations outside
the limits of the improvement unless otherwise directed by the
Engineer. The Contractor shall not dispose of surplus excavated
material on corporate or private property without first securing
written permission from the Owner or Agent of the property.
The Contractor shall do all pumping and bailing, well pointing,
build all drains, and do all other work necessary to keep the trench-
es clear of water.
No claim for an amount of money in excess of the contract price for
the work will be considered or allowed because of the character of
Subdivision Specifications Page 28.
the ground in which any trench or other excavation is made and /or
when special foundation material is required. The Contractor shall
assume the risk of meeting water, quicksand, hard pan, boulders, clay,
rubbish, unforeseen obstacles, pavements, etc.
Sidewalks shall not be obstructed and the Contractor shall make
provision, where necessary, for the free passage of pedestrians.
Hydrants shall not be buried, and shall at all times be maintained
fully accessible to fire department personnel.
Sheeting and Bracing: The Contractor shall furnish and put in
place such braces, sheeting, etc., as may be necessary for the protec-
tion of the workmen, the work, the public safety, and adjacent struc-
tures, pipes, conduits or other improvements.
Sheeting and bracing may be removed after the backfilling has -been
completed or filled to an elevation to prevent caving of the sides of
the excavation. All voids and holes left by the sheeting after being
removed shall be carefully filled with fine sand and thoroughly com-
pacted by special tools or puddling.
The contract price shall be understood to include the cost for all
sheeting and bracing that may be necessary to insure safe perform-
ance of the work until the backfilling is complete.
Underground Utilities: The information presented on the plans
showing the approxima a location of private and /or public underground
utility lines is of an approximate nature only and is included for
the information of the Contractor. Information was obtained from
available existing records and the Engineers shall not be held- -
responsible for underground utilities whose location does not corre-
spond with the information on the plans. Prior to starting construc-
tion, the Contractor shall request all public or private agencies,to
establish the field location of their underground utilities.
The Contractor shall make such exploration as is necessary to
determine the exact location of all underground utilities, and shall
exercise sufficient care during the progress of work in the area to
prevent damage to the utilities. Whenever, in the progress of the
work, it becomes necessary to relocate any underground gas mains,
telephone conduit or electrical lines, it shall be the responsibility
of the utility company involved to make such relocation. It is the
Contractor's responsibility to properly notify each utility agency
in sufficient time so as to avoid interference with the progress of
the work.
Where it is necessary for the Contractor to relocate water or other
pipes or conduits in direct conflict with the proposed pipe (exclu-
sive of culverts) for which no public utility is responsible, in
order for the work to proceed, and such relocation is not called for
on the plans, the Contractor shall be allowed an extra, the amount of
which shall be negotiated before the work is commenced.
All existing underground utility pipes, conduits or cables shall be
carefully supported and protected until the new pipeline is laid and

the backfilling finished, or until the proper utility agency removes
or changes them. Any damage done to such existing pipes, conduits or
cables shall be immediately repaired or the damaged parts replaced by
the Contractor. It shall be the Contractor's responsibility to noti-
fy each and all persons, firms or corporations using or.responsible
for any private or public underground utility pipes, conduits, cables
and related structures, of the time or times he shall be working in
the area of their facilities.
Bedding of Pipe: The Contractor shall bed the lower quadrant of
the pipe on a layer of gravel or crushed stone. Gravel or crushed
stone shall pass a 3/4 inch sieve, and shall have a minimum thickness
of 4 inches under the pipe barrel and 2 inches under bells, and shall
be carefully placed and compacted around the pipe to provide uniform
support to the bottom quadrant.
If, in the excavation of the trench, the excavation has been made
deeper than necessary, bedding material as specified above shall be
used to fill the trench to the required grade.
Backfilling: After the pipe is laid the Contractor shall immed-
iately re-fill the trench, except that in trenches for pipe requiring
pressure testing, pipe joints shall remain exposed until completion
of pressure testing. Backfill around the sides to the top of the
pipe shall be carefully deposited and thoroughly compacted by hand
tamping in 6 -inch layers (loose measure). Backfill shall then be
carefully placed to a level of 12 inches over the top of pipe. Only
selected material which is free of large stones, clods, roots, etc.,
shall be used for this purpose. After the pipe has been covered as
described above, the remaining depth of the trench shall be back -
filled and compacted using excavated material unless such material is
determined by the Engineer to be unsuitable. Unsuitable excavated
material shall be removed from the area by the Contractor and dis-
posed of as stated under EXCAVATION, and shall be replaced with
suitable backfill material. No additional compensation will be allow-
ed for such removal and replacement of unsuitable material. All
backfill material shall be deposited in the trench in a manner such
as not to damage the pipe or disturb its grade or alignment. The
surface of the backfill shall be left smooth, sufficiently crowned to
allow for settlement.
Any trenches in which settlement occurs during the period of con-
struction and within one year of the date of acceptance of the
project shall be brought back up to the surrounding grade, and the
surfaces restored as required under the appropriate sections of this
specification.
Special Backfill: Wherever the excavation is in streets, parking
areas, driveways, or other paved areas, the trench shall be back -
filled from the bottom to within 12 inches of the surface with gravel,
crushed stone, or other approved granular backfill material, jetted
for compaction. All surplus excavated material shall be removed from
the area and disposed of by the Contractor, as stated under EXCAVA-
TION.
Subdivision Specifications Page 30.
The top 12 inches of the trenches in streets, parking areas, drive-
ways, or other paved areas shall be filled with approved road gravel
or crushed stone as a temporary pavement, and shall be maintained
level with adjoining pavement surfaces until the original type of
pavement (or equal) is replaced.
Removal of Existing Pavement Surfaces: The Contractor shall remove
an lspose or all existing pavement surface materials as necessary
to complete the pipeline trench construction. All existing Portland
Cement concrete street and driveway pavements, including surfaces,
bases and stabilized sub - bases, curbs and gutters, and sidewalks
shall be removed to a width of not less than one foot on undisturbed
ground on each side of the trench excavation. A saw cut to a minimum
depth of 12 inches shall be made with a concrete sawing machine to
provide a straight line joint between the existing pavement, curb and
gutter or sidewalk which will remain and the portion to be removed
and replaced. All debris from this work shall be removed from the
area and disposed of as stated under EXCAVATION. No pieces of broken
pavement, curb and gutter or sidewalk shall be deposited and buried
in the backfilling of the trench excavation.
Replacement of Pavement Surfaces: The Contractor shall reconstruct
all street and-driveway pavements including surfaces, bases and
stabilized sub - bases, curbs, and gutters, and sidewalks as required
for the complete replacement of existing pavement surfaces which were
removed for pipeline trench construction or which were damaged or
destroyed by the Contractor's operations outside of the limits of the
trench excavation. This work shall not be started until the trenches
have been properly backfilled and thoroughly compacted as stated
under SPECIAL BACKFILL, and all manholes, valve vaults, inlets,
service boxes and other similar structures and appurtenances have
been set to the established ground surface grade. The work shall be
constructed in accordance with applicable provisions of and the most

special backfill and surface restoration work as required by the
foregoing specifications shall be included in the Contractor's lump
sum bid, and no separate payment will be allowed for these items.
Subdivision Specifications
Page 33.
When the work is being done on a unit price basis (either under a
unit price bid or as additions or deductions to a lump sum bid) the
quantities for payment for special backfill and surface restoration
shall be determined in accordance with the following methods of
measurement unless otherwise stated in the Proposal.
Special backfill quantities shall be computed on the basis of the
cross - sectional area of the trench from invert to ground surface,
less the cross - sectional area of the pipe, but payment will not be
allowed outside of backslopes of three inches per foot from the
maximum trench width at the top of the pipe, as specified under
EXCAVATION.
Quantities for surface restoration shall be computed from the
actual width at the top of the trench, up to a maximum width defined
by backslopes of 3 inches per vertical foot from the maximum trench
width at the top of the pipe, as specified under EXCAVATION, (plus
2 feet in the case of Portland Cement concrete street and driveway
pavements, curbs and gutters, and sidewalks). No payment will be
allowed for removal and replacement in excess of the above maximum
width.
Work in Highway Rights -of -Way:
Attention is called to construction work in the rights -of -way of
Township, County, State and Federal highways where required by the
locations shown on the plans. All such construction work shall con-
form in all respects with the requirements of the controlling
authority. It shall be the Contractor's responsibility to execute
all necessary highway permit forms, provide and pay for any bond
requirements, and to execute and comply with any required Traffic
Control Authorization Requests. The Contractor shall also notify
the highway authority involved of the proposed work schedule in
highway rights -of -way.

trench, the contractor shall perform all ditching, grading and sh.a.p-
ing necessary to restore the original drainage in the area of work.
Culverts removed during the course of the work shall be reinstalled
as soon as practicable. Culverts damaged by the Contractor shall be
repaired to a condition equal to the original pipe or be replaced
with new culvert pipe of the same size, length and material.
Lines and Grades: The Engineer will provide the Contractor with
initial ine and grade as stated under SURVEYS on page 1 -3 of the
GENERAL CONDITIONS. It shall be the Contractor's responsibility to
transfer the line and grade to the bottom of the ditch. Three batter
boards, a top line and grade pole shall be used for this purpose. No
other method of transfer shall be used unless approved by the
Engineer in writing.
The Contractor must test the pitch or grade of the top line and
will be held responsible for the correct flow in sewers. An accurate
line level shall be used to test the downward grade of the pipe in
the direction of flow. No claim for extra work will be allowed for
alleged inaccuracy of grade and /or line stakes.

Sewer Crossings: Whenever water mains must cross house sewers,
storm d rains or sanitary sewers, the water main shall be laid at an
elevation such that the bottom of the water main is at least 18 in.
above the top of the drain or sewer wherever possible. This vertical
separation shall be maintained for that portion of the water main
located within ten feet horizontally of any sewer or drain crossed,
said ten feet to be measured as the normal distance from the water
main to the drain or sewer.
Where conditions exist that prevent this minimum vertical separa-
tion from being maintained, or where it is necessary for the water
main to pass under a sewer or drain, it will be necessary to center
a length of water main pipe on the sewer to be crossed so that the
joints will be equidistant from the sewer and as remote therefrom as
possible. Where a water main must cross under a sewer, a vertical
separation of at least 18 inches between the bottom of the sewer and
the top of the water main shall be maintained, along with adequate
means to support the sewer lines to prevent their settling and
breaking.
Valves, Vaults and Boxes: Gate valves shall be iron body, double

2J inch hose nozzles and a 42 inch pumper nozzle and shall be of
break flange construction unless otherwise shown on the plans. All
nozzle threads shall be National Standard unless otherwise required.
Each hydrant shall be furnished and installed with a 6 inch
connecting pipe and a 6 inch auxiliary gate valve. Hydrant and valve
joints shall be of the same type used for the water main to which
they are connected. Auxiliary valves shall be furnished with valve
boxes and covers. Box covers shall have the word "water" cast in the
upper surface. All hydrants shall be fitted with 0 -ring packing and
a National Standard operating nut.
Each hydrant shall be set vertically on a concrete block having
sufficient area and thickness to support it. The bottom casting of
the hydrant shall be securely blocked with dry masonry and the barrel
shall be braced in a manner such as to hold it plumb. The Contractor
shall place at least 1/4 yard of washed, crushed stone or gravel in
an excavation around the bottom of the hydrant to provide space_ for
drainage. When backfilling, the earth shall be well tamped in 6 in.
layers around the barrel of the hydrant and the valve box. Care
shall be taken to ascertain that both the hydrant and the valve box
remain plumb and undisturbed. The hydrant shall be set so that the
lowest hose connection is not less than 18 inches nor more than 24
inches above finished grade.
Testing: All water main pipe, fittings, joints, valves and hyd-
ran s s all be subjected to a hydrostatic pressure of 125 p.s.i.g.
after installation but before the joints have been covered. That:
portion of the water main to be tested shall be filled with water,
all air shall be expelled and the above test pressure shall be
applied by use of a pump connected to a tap in the pipe. The above
pressure shall hold without loss and without further application of
pressure for a period of at least 10 minutes. In the event of loss
of pressure the Contractor shall locate all leaks and do all of the
work necessary to stop them.
After the test at the pressure of 125 p.s.i.g. has been completed
and the given conditions have been met the water main shall be tested
at the Owner's pressure for 24 hours and the maximum allowable leak-
age as determined by meter shall be 20 gallons per mile of water main
per inch of pipe diameter per 24 hours. The water main will not be
accepted until-the leakage is less than the allowable stated above.
It shall be the Contractor's responsibility to furnish all material
and labor to complete the testing. The Contractor shall satisfy him-
self that the tests can be successfully completed prior to requesting
the Engineer's presence for the official tests.
The Contractor shall notify the Engineer at least 48 hours in
advance of time that official tests will be made. Depending on
traffic conditions, public hazard, or other reasons, the Engineer may
direct when tests of completed sections of mains shall be made, and
may order such tests to be made in relatively short sections.
Subdivision Specifications Page 37.
Disinfection: After the new work has been completed, pressure
tested an ound to be satisfactory, the Contractor shall furnish the
equipment and the materials necessary to properly disinfect the sys-
tem in accordance with the applicable portion of the most recent
"Procedure for Disinfecting Watermains" as approved by the American
Water Works Association.
This "Procedure" generally provides that the disinfecting solution
contain not less than 50 parts per millions of available chlorine and
that it shall remain on contact with the new work for a period of not
less than 24 hours and that after the solution has been retained for
the required length of time, the chlorine residual at the extremities
of the new work and at other representative points shall be not less
than 25 parts per million. The "Procedure" also provides for the
method of applying the disinfecting agent, flushing, testing, etc.
After the system has been disinfected and then flushed so as to be
free of chlorine, the Contractor using proper sampling bottles, shall
collect water samples from the new system. These samples shall be
shipped to a State approved laboratory for bacteriological analysis.
In Illinois satisfactory samples must be obtained on two consecutive
days.
The Owner will not accept the new work until notification has been
received from the laboratory that the samples examined showed that
the water from the new work was at least equal in bacteriological
quality to that of the water served the public from the existing
water supply system if the new work is in connection with an existing
system, or in the case of a new system, that the new work was free
of contamination at the time the samples were collected.
9.210 Sanitary Sewers.) Sanitary sewers of not less than 8 inches
in diameter and minimum four foot lengths shall be provided along the
frontage of all lots in such a manner as to adequately serve all lots
and tracts with a connection to the system. Sanitary sewers are to

be cons ructed of Precast Reinforced Concrete Manhole Sections meet-
ing the requirements of ASTM Designation C478 (latest revision).
Sections shall be joined using either flexible watertight rubber
gaskets or preformed bituminous plastic gaskets as specified under
JOINTS. Precast tops shall be concentric cone unless otherwise indi-
cated. Flat slab tops will be permitted only for manholes whose
depth is insufficient to allow cone sections to be used. Not more
than eight inches of grade ring will be permitted unless more is
specifically called for on the plans or by the Engineer in the field.
Precast manhole bottoms shall be carefully bedded on a 2 inch compact-
ed sand cushion. Spaces around and under all pipes entering at the
bottom of manholes shall be filled with concrete from the outside.
Manhole frames and solid covers shall be of the type shown on the
manhole detail. All frames and covers shall be furnished with
machined contact surfaces. Bolted and gasketed covers shall be pro-
vided where specifically designated. Manholes over 3 feet deep shall
be provided with cast iron steps in accordance with the manhole
detail.
Manhole Inverts: All sewer pipe shall be laid through manholes so
as to provi Uea smooth and uniform invert.
The contractor may provide pre - manufactured inverts or cut the top
half out of the pipe after installation. All cutting on the job

shall be done with a power driven saw. Sawing of pipe shall be done
prior to completing the manhole to afford proper ventilation for the
workmen.
Where wye or tee connections are required in a manhole, the con-
tractor shall provide fittings or butt -joint to the through pipe.
If a butt joint is utilized, the spigot end of the lateral pipe
shall be saw cut at an angle to provide a close proximity of inverts
being joined. After the invert of the manhole is poured, the wall of
the main sewer shall be broken out by hand methods to fit the opening
of the lateral sewer and form a smooth transition.
At manholes where the main sewer turns, the contractor shall pro-
vide long radius bends or elbows as required to carry the sewer
through the manhole. The contractor may provide pre -cut or job -cut
sections as outlined above.
Building Service Connections: The Contractor shall provide and
ins =a 6 Inch branch fittings, riser pipes, and building service
lines to the property line. Building service lines shall terminate
at a distance from the sewer as indicated on the plans, and at an
invert elevation of not less than 22 feet below the basement floor
level of the building to be served, unless otherwise directed.
Building service connections shall conform in materials and workman-
ship with the specifications for the other sewers in this project,
and with the Building Service Detail.
The Contractor shall keep a record on forms available from the
Engineer of all branch fittings, riser pipes and building service
lines by measurement to the nearest downstream manhole. Such records
shall be delivered to the Engineer on completion of the work. The
end of each service line shall be marked by one of the following two
procedures. Where curbs or sidewalks are available, the Contractor
shall notch the top of curb or back side of the walk directly oppo-
site the end of the sewer service. Where curbs or walks are not
available he shall furnish and place an 18 inch long hardwood stake
flush with the ground surface, on the property line directly opposite
the end of the service line.
The Contractor shall include in his total bid price the cost of
providing the number of branch fittings and the footage of riser pipe
and service lines shown on the plans. The length of riser pipe shall
be taken as the vertical distance from the centerline of the sewer at
the branch fitting to the termination of the riser pipe. The length
of a service line shall be taken as the horizontal distance from the
centerline of the sewer at the branch fitting to the termination of
the service line.
TV Inspection of All New Sewers Required:
The Village Engineer of the Village of Deerfield is directed,
prior to final approval of any newly installed sewer system and /or
reconstructed sewer, to require that any and all contractors cause to
be made an inspection, under the Village Engineer's supervision and
direction, by closed- circuit television of the entire sewer system

installed, showing thereby that the sewer system has been constructed
in accordance with the Municipal Code and accepted sound engineering
basis and that the sewer system is free of any and all accumulations
of foreign substance and nature and that the passage and flow of
sewage and storm water is free and clear, and that there are no
structural defects. If, in the discretion of the Village Engineer,
the sewers are large enough for a visual inspection to be made, in
lieu of an inspection by closed- circuit television, such a visual
inspection shall be made and a report of such inspection submitted to
the Village.
Upon completion of such inspection and upon receipt of a written
report of such inspection, together with such photographs as may
have been taken, and, if satisfied that such sewer is free and clear
of all foreign substance, and free of any engineering defects, the
Village Engineer is authorized to approve same as a final inspection,
placing in safekeeping all inspection records and photographs for
future reference by the Village.
The cost of such television inspection and /or inspection reports
shall be entirely paid for by the Contractor or developer of such
land and /or sewer system, and said inspection report, together with
such photographs as may have been taken, shall remain the property
of the Village.
9.211 Storm Sewers.) Storm sewers of not less than 10 inches
diameter shall be provided along the frontage of all lots in such a
manner as to adequately serve all lots or tracts with a connection to
the system. Storm flows are to be computed on the basis of one of
the following formulae:
1. Q - Air, where
Q is total quantity of flow in cubic feet per second
A is the area to be drained, in acres
I is the coefficient of runoff, and
R is the rate of rainfall, assumed 2 -3/4 in. per hour.
2. Q - MRc 4 IS/M, where
Q is total quantity of flow in cubic feet per second
M is the drainage area in acres
R is the rate of rainfall, assumed 2 -3/4 in. per hour
C is the coefficient of runoff
S is the slope of the ground in feet per 1000 feet-
The coefficients, unless varied by the Village Engineer, shall be
I equals 0.40 and C equals 0.30. The sewers will be designed in such
a way as to insure a minimum velocity of flow of 3 feet per second
and a maximum velocity of flow of 10 feet per second. Storm sewers
shall be constructed in accordance with and the materials used shall
be in compliance with the methods and materials required in Section.
