A.
Preconstruction meeting.
(1)
A preconstruction meeting shall be requested by the developer
and scheduled through the Town Building Department prior to the start
of construction of a development. The developer, his contractor and
design engineer shall meet with all private utility representatives;
Town department heads and project observers to discuss the overall
project, its impacts and schedules. A schedule of construction shall
be presented in writing at this meeting by the site contractor as
well as copies of the fully approved drawings.
(2)
Prior to scheduling a preconstruction meeting, the developer
shall obtain a checklist from the Town Building Department, identifying
all items that the developer must bring to the meeting.
B.
Meaning of drawings. The contractor shall abide by and comply with
the true intent and meaning of all drawings and of the specifications
taken as a whole. If the contractor believes that the construction
indicated on the project drawings will not, when executed, produce
safe and substantial results, or if it appears that there is any discrepancy
in the drawings, it is his duty to immediately notify the developer's
engineer, in writing, and to thereafter proceed only upon written
order of the Town.
C.
Protection of property and work.
(1)
Conduct of operations. The contractor shall conduct his operations
to prevent damage to trees, garden plots, shrubbery, pipelines, conduits,
buildings and other structures. The contractor shall use all necessary
precautions to protect the work and adjacent structures of all kinds
during construction and shall so conduct his operations that at no
time shall the work or such structures be endangered.
(2)
Responsibility and damage. The developer shall be responsible
for all parts of his work, temporary or permanent, until the project
is complete and shall thoroughly protect all work, finished or unfinished,
against damage from any cause as all work is at the contractor's risk
until the same is accepted by the developer. The use of part or all
of the work by the Town as provided for in these specifications shall
not relieve the developer of this responsibility. The contractor shall
be responsible for damage to life and property due to his operations
and shall provide all necessary guards, rails, night lights, etc.
D.
Construction schedule. The developer shall provide a construction
schedule showing the order in which work will be completed at the
preconstruction meeting. The schedule shall be reviewed at the preconstruction
meeting and revised if necessary. No work will begin until a schedule
acceptable to the Town is on file with the Town.
E.
Permits. The developer shall secure all necessary permits from the
Town, including Highway, Water Utilities, and Watershed Departments,
and/or any other agency which may have authority over any work prior
to the start of construction.
F.
Existing utilities or structures.
(1)
Before construction begins near any existing utility or structure,
the contractor shall notify the appropriate owner of his intention,
and their instructions as to the protection of their property must
be followed. Before commencing work, the contractor shall determine
the exact location of any structure or underground utility in order
that the contractor's project will not damage or disrupt these facilities.
(2)
The contractor shall take necessary precautions to prevent entry
of mud, debris, etc., into existing utilities or onto streets near
the site.
(3)
All existing underground facilities shall be checked for damage
before backfilling. In the event a facility is damaged, the owner
of that facility shall be notified by the contractor so as to ensure
an acceptable repair and/or replacement.
G.
Facilities for observation. The contractor shall furnish all reasonable
facilities and aid to the construction observers for safe and convenient
footways, scaffolds, ladders, etc., that may be needed for the examination
and review of any part of the work. The Town of Ontario may stop work
when the contractor has no responsible agent on the project or if
the Town feels that the contractor is not performing the work in the
best interests of the municipality. Disorderly, intemperate and incompetent
persons shall not be allowed on the project. The employees who neglect
or refuse to follow the construction observer's instructions shall
be permanently removed from the project by the contractor. Failure
to conform to these controls may warrant refusal of the municipality
to consider the development for dedication.
H.
Layout. It shall be the responsibility of the developer to have the
work carefully laid out by qualified surveying or engineering personnel
in a manner that will assure accurate completion of the work.
I.
Defective work. The review of the work shall not relieve the developer
of any of their obligations to comply with the specifications. Any
defective work shall be made good, and any unsuitable materials which
have been previously overlooked by the Town or its representatives
shall be removed and replaced. If the work or any part thereof shall
be found defective at any time before the final acceptance of the
project, the developer shall make good such defect in a manner satisfactory
to the Town.
A.
Completion of grading per the grading plan to within one foot of
design grade shall precede any trench excavation. Such grading shall
include house "pads," removal of enough material to form the "box"
for road base, surface drainage channels, required temporary situation
basins, etc.
B.
Construction brush and debris will not be buried on the site. Wood
materials shall be cut, chipped, mulched or removed from the site
and deposited in a permitted construction/demolition landfill.
A.
Excavation.
(1)
Under this term will be included all excavation in trenches
and pits, together with all backfilling and embankments that may be
needed for the laying of the utilities and appurtenances or that may
be necessary for the laying, changing and construction of any water,
sewers, conduits, culverts, drainage ditches or watercourses, or for
any other incidental work that may be required or ordered by the Town
or its representative.
(2)
It is the contractor's sole responsibility to make sure that
all work shall be conducted in strict accordance with the Federal
Safety Standards of OSHA.
B.
Width of trenches. The trenches shall be of such width as may be
required by the design engineer to ensure proper laying and handling
of the pipes and appurtenances and proper tamping and backfilling
operations. In all cases, trenches should be kept as narrow as possible.
The contractor shall be responsible to provide sheeting/bracing or
other requirements to ensure the safety of his workmen in conjunction
with the proper installation of the pipe.
C.
Depth of trenches.
(1)
In general, the trenches shall be excavated to such a depth
to properly install utilities to the grade established in the field
by the design engineer. The depth of the excavation shall allow the
proper bedding material to be placed under the pipe.
(2)
Any extra excavated depth by the contractor shall be filled
with compacted crushed stone to the proper grade required.
(3)
Utilities shall be designed to prevent damage from frost penetration
or surface forces. Water mains and services shall be generally buried
with four feet six inches of cover in fields but at least six feet
zero inches when they cross existing or proposed roads.
D.
Tunneling. Work shall generally be conducted in open trenches or
excavations, with proper protection. Tunneling shall be done only
in areas specifically called for by the design plans, with design
details approved by the Town.
E.
Blasting. Whenever necessary to resort to blasting for making the
excavations, the trench shall be covered in a form to prevent fragments
of rock from being thrown out. Only experienced, licensed workmen
shall be employed in the handling and uses of explosives. All blasting
operations shall be conducted in strict accordance with existing ordinances,
regulations and specifications relative to rock blasting, storage
and use of explosives.
F.
Bailing and draining. The contractor shall furnish a sufficient pumping
plant and shall provide and maintain, at his own expense, satisfactory
drainage whenever needed in the trench and other excavations during
the progress of the work and up to final inspection. No structures
shall be laid in water. Water shall not be allowed to flow or rise
upon any concrete or other masonry or flow on adjacent lands. All
water pumped or bailed from the trench or other excavation shall be
conveyed in a proper manner to a suitable point of discharge and may
require temporary siltation traps.
G.
Bottom of trench.
(1)
The bottom of the trench shall be carefully graded and formed,
according to the directions of the design engineer, before any structures
are laid thereon. When other instructions or design are not indicated,
all trenches shall be excavated in a straight line. In hard pan, boulder
formations or rock, the excavation shall extend at least six inches
below the bottom of the pipe and a carefully compacted bed of crushed-stone
screenings placed in the bottom of the trench up to the level of the
spring line of the pipe. See Appendix JJ for specific material bedding
requirements.[1]
[1]
Editor's Note: Appendix JJ is included at the end of this chapter.
(2)
It is the intention of this specification to achieve not less
than Class B pipe bedding.
H.
Suitable bedding and safety backfill material. It shall be the responsibility
of the contractor to generally utilize material excavated from the
trench in order to provide the required backfill to meet the listed
specifications, unless crossing an existing or proposed road. Should
the nature of the soil be such that the contractor is unable to meet
the above requirements by selecting, with reasonable care, from the
excavated material, he shall provide the following materials, if so
ordered by the Town or its representative:
(1)
Sand, stone or concrete cradle when the trench bottom does not
provide sufficient bearing capacity or when specification requires
specific bedding for certain utilities.
(2)
Sand encasement shall be ordered by the Town when the trench
is excavated in rock, boulders, or hard pan and none of the material
above this level is suitable for backfilling the pipe.
A.
Line and grade. All pipes and appurtenances of whatever character
shall, when set, conform to the alignments and grades required by
the design engineer. All of the required special castings and other

The contractor shall use suitable tools and appliances for the
safe and convenient handling and laying of all utilities and appurtenances.
All pipes and castings shall be carefully examined by the contractor
for defects, and no pipe or casting which is known to be defective
shall be laid. If defective pipe or castings should be discovered
after being laid, these shall be removed and replaced with sound pipe
or castings. The pipes shall be cleaned before they are laid and shall
be kept clean until they are accepted with the completed work. All
ends of the pipes shall be watertight, capped to exclude water and
debris from entering the pipes.
(2)
Sewers shall be built to the lines and grades between manholes
as shown on the project drawings. The contractor shall provide sufficient
grade control to properly install the pipe and appurtenances. Sewer
pipe shall be laid upgrade with spigots placed in the direction of

below finished grade and continue to the top of the bench wall.
(9)
It is the intent of these specifications to construct first-class
manholes which will exclude all groundwater by means of carefully
constructed foundations, tight barrel joints and the coating of the
inside and outside of the manholes.
B.
Frames and covers. The frames shall be firmly set in a bed of not
less than one full inch of cement mortar and adjusted to the finished
grade. The manhole frame may be set directly on the concrete roof
slab, provided the top will be at the proper grade; otherwise, precast
concrete spacers or bricks shall be mortared to the roof slab to raise
the frame to the proper grade. A maximum of three courses of spacers
or bricks shall be used to adjust the frames and grates to the proper
grade.
C.
Inverts. Inverts shall be constructed in all manholes. The inverts
may be constructed of the mainline pipe or brick (Grade SS) and shall
be the depth of the pipe. When PVC material is used, all brick, concrete
or other masonry material that interfaces with the PVC shall be adhered
to the PVC with 100% epoxy nonshrink grout.
D.
Drop manholes.
(1)
Wherever the invert of the entering sewer is more than two feet
above the invert of the outlet sewer, it shall be connected with a
vertical outside drop with a cleanout pipe half bricked up. When drops
are placed, the entire excavation around the drop pipe shall be filled
with 3,000 psi concrete extending not less than two feet along the
main sewer.
(2)
The cleanout opening in the barrel of the manhole shall be cut
in after the manhole wall pipe is in place, and the joint between
the cleanout pipe and the manhole wall shall be thoroughly sealed
with cement mortar on the inside and bituminous joint material on
the outside.
E.
Shallow sewer manholes. Where any manhole is less than four feet
from invert to bottom of roof slab, the contractor is to provide a
manhole as shown in Appendix S.[1] The roof slab shall be precast structural concrete reinforced
to withstand a concentrated H-20 load plus 30% impact. The slab shall
be formed to fit into the ends of the vertical pipe and shall have
a full bearing for its entire circumference.
[1]
Editor's Note: Appendix S is included at the end of this chapter.
F.
Sealing of manholes. All manholes shall be sealed with two coats
of sealer as applied by the manhole manufacturer to the entire interior
and exterior surfaces in minimum dry thickness of 11 mils per coat.
Application shall be in accordance with the coating manufacturer's
recommendations and shall be certified thereto by the suppliers. Before
placement in the field, abraded areas shall be touched up with two
coats by the contractor. Covers and other exposed surfaces shall also
be coated in the field. Improper materials or mil thickness shall
be cause for rejection of manhole sections.
A.

installed structures.
B.
Backfill immediately after approval. Only select earth material shall
be deposited around the utility and appurtenances, covering them by
hand for a depth of at least 12 inches above the pipe. This earth
shall be thoroughly tamped as it is being placed so as to fill the
lower portion of the trench thoroughly to give utilities a Class B
bed for their entire length.
C.
Restrictions as to materials. No rock or frozen materials shall be
placed in trenches within existing or proposed streets. Such material
may be used in fields where immediate compaction is not necessary
and at least two feet of select fill has been placed over the pipe.
D.

(3)
Samples. After flushing of the newly disinfected main, the Town
of Ontario Water Utilities Department shall obtain samples of water
and submit them to a laboratory approved by the New York State Department
of Health. Upon the receipt of a satisfactory laboratory report, this
information, together with the Town Engineer's certificate of construction,
shall be submitted to the New York State Department of Health for
approval. Upon receipt of the approval of completed work from the
Health Department, the water system shall be considered complete and
may be accepted for service by the Town.
F.
Defective areas.
(1)
In any areas where satisfactory results of applied tests cannot
be obtained, the defective portion of the system shall be located
and replaced with new material.
(2)
That portion of the system shall then be retested until satisfactory
results are obtained. Use of repair clamps will not be permitted by
the Town.
A.
General information.
(1)
The contractor shall not proceed to construct any surface improvements
until the underground system has been installed, tested and approved
by the Town.
(2)
Careful attention shall be given by the contractor to obtain
the necessary compaction densities as specified. All surface improvements
shall be constructed to the shape and dimensions as shown on the typical
sections or on the approved plans. A greater road width and base may
be required in those areas where particular soil conditions or traffic
patterns require special considerations.
A.
Subgrade.
(1)
The subgrade shall be graded to remove all unsatisfactory or
unstable material. Where material is removed below the subgrade elevation,
suitable granular material shall be used to bring the road to proper
subgrade. Where groundwater or poor soil conditions exist, the developer
shall be required to install perforated underdrain and crushed stone
weeps to drain the base. The entire subgrade surface shall be thoroughly
compacted according to NYSDOT Standard Specification 203-3.12.
(2)
Fabric filter material may be required by the Town to stabilize
the base or subbase before the contractor proceeds to install same.
(3)
No movement shall be observed in the subgrade material as the
roller passes. When the subgrade is completed, the contractor shall
so notify the Town Superintendent of Highways and the Town Engineer
for a base determination. Upon the review and written approval of
the subgrade by the Superintendent of Highways and the Town Engineer,
the base material may be placed.
B.
Base material.
(1)
Approved base materials shall be uniformly deposited and compacted
in layers with a roller, according to NYSDOT Specifications. Rolling
shall begin at the sides and continue toward the center and shall
continue until there is no movement of the course ahead of the roller.
After compaction, the top surface of this course shall not extend
above the theoretical elevation for this course, and, when tested
with a straight edge 16 feet in length, any bump or depression over
1/4 inch from the theoretical grade line shall be satisfactorily eliminated.
(2)
When the base has been prepared to the satisfaction of the Superintendent
of Highways, the developer may place the binder course. If base conditions
are changed, as determined by the Superintendent of Highways, before
the binder is placed, he may order the developer to seal the stone
with a rapid-sealing liquid asphalt emulsion as specified in NYSDOT
Standard Specification Section 702-6, ashpalt emulsion tack coat,
with 0.5 gallon per square yard as determined by the conditions and
not more than 24 hours prior to placement of binder asphalt.
(3)
If the compaction of the base is questionable by the Superintendent
of Highways, he may require rerolling or stone replacement by the
developer.
C.
Bituminous pavement.
(1)
Binder shall be placed and compacted to a minimum finished layer
thickness of three inches with a self-propelled asphalt spreader and
rolled according to NYSDOT Specifications 403-3.03. Before applying
the top course, any irregularities in the binder course shall be eliminated,
but at no time will "cold patch" or "winter mix" be allowed on the
binder for repair work.
(2)
Before the surface course is placed, the binder will be cleaned
and inspected by the Superintendent of Highways to determine the condition
of the pavement. It may be necessary to apply a tack coat at the rate
of 0.1 gallon per square yard before placing the surface.
(3)
Surface course shall be placed and compacted to a minimum finished
layer thickness of one inch with a self-propelled asphalt spreader
and rolled in accordance with NYSDOT Specifications 403-3.03.
D.
Temporary road construction.
(1)
Where construction sequences preclude the specified road construction
items and these requirements for certificates of occupancy, a temporary
road consisting of the specified road section less top surface course
may be constructed.
(2)
This temporary road shall be reviewed by the Superintendent
of Highways and approved in writing prior to the issuance of any certificate
of occupancy. The Town Board may accept dedication of the road if
sufficient moneys remain in the financial guaranty to top the road
in the next year.
E.
Continuation of existing road.
(1)
When construction of a road is continued from an existing road
or previously developed section, the pavements shall be joined with
a triangular cut of at least 15 feet from the edge of the pavement
to the center line of the old pavement. The intent of this provision
is to eliminate any grade difference and make a smooth riding transition.
(2)
All pavement joints shall receive a tack coat before placing
the binder or top course.
F.
Stabilized shoulders. Stabilized shoulders shall be constructed to
the dimensions shown on the typical sections in Appendix HA.[1] Construction methods shall conform to NYSDOT Specification
410-3.01. The base course shall consist of a wedge of crusher-run
stone with a single surface treatment.
