The Board of Trustees of the Incorporated Village of
Munsey Park may, from time to time, at its discretion, authorize the reconstruction
of portions of existing concrete sidewalks which abut the Village streets.
The Board expects the required work to be done as expeditiously
as possible with a minimum of inconvenience to the residents and the traveling
public. Toward this end, the contractor will be required to return with his
conformed contracts, a notarized statement indicating to the Village Board
the date on which he intends to commence work. This statement must be signed
by an officer of the contracting company. The Village will then, relying on
the contractor's notarized statement, notify all of the residents who
will be affected by his work of the proposed date on which the work will commence.
Failure by the contractor to commence work on the date specified in his notarized
statement will result in the deduction of $500 from the contractor's
final payment for each day of delay in the commencement of work. Weather will
not be considered to be a reason for failure to commence work on the date
specified. Other reasons for the delay of starting may be submitted for consideration
of the Village Board, but such a request must be made in writing at least
five days prior to the proposed original start-up. If the Board agrees to
the delay and waives the $500 deduction, a new commencement date shall be
mutually agreed to, and the original procedures will then be reinstated, including
the $500 deduction if the new start-up date is missed.
Prior to breaking up the sidewalk at any residential
driveway, the project foreman, or his designated representative, shall ring
the resident's bell and advise the resident of the impending breakup
at the driveway and make sure that the resident understands that no vehicles
will be permitted to use the new sidewalk until at least 72 hours after the
concrete has been "finished." The resident will have to arrange to find an
alternate location to park his vehicle if he intends to use it within the
72 hours required to cure the concrete.
At the front of the walk leading to each residence, the
contractor shall provide planking or other acceptable means for the residents
to enter and leave their home.
Between the curb and the sidewalk which is to be removed
and replaced on each side of Park Avenue and on Manhasset Woods Road, is a
grass strip of approximately 12 feet, which may contain underground sprinkler
lines and heads. If, in the process of removing and replacing the sidewalk,
the contractor should damage the twelve-foot grass area, the sprinkler systems
or the existing driveway apron which leads from the street to the sidewalk,
the area will have to be restored to its original condition. This may require
the placement of topsoil and grass seed or sod as directed, and, in the case
of the aprons, repair of any concrete damaged by the contractor, i.e. cracked
or broken, all at no cost to the Village.
If it appears that the sidewalk to be removed is part
of an adjacent driveway, either concrete or blacktop, or walk or apron, the
contractor shall saw cut the material along the length of the physical connection
to insure a neat, workmanlike job. There will be no extra compensation for
saw cutting.
If, during the removal of the old walk and prior to the
placement of the new concrete, it appears that existing tree roots may interfere
with the pour, the condition shall be called to the attention of the Engineer
who will instruct the contractor on how to proceed. Cutting of major portions
of the tree root system shall be avoided whenever possible.
Upon the completion of the work, and after the concrete
has set sufficiently to permit the removal of the forms, topsoil shall be
used to fill in the void between the new walk and the original grass area.
If any subgrade should be encountered which is deemed
to be unacceptable, the material shall be removed, and bankrun be brought
to the site to replace the poor material. Such bankrun will be paid for at
the price per cubic yard as established from time to time by resolution of
the Board of Trustees,[1] which price is to include all of the contractor's costs to
supply and place the material. The Engineer will have to approve the removal
and replacement of poor material.[2]
Transverse one-half-inch expansion joints shall be placed
at approximately forty-foot intervals, so as to finish flush with the finished
walk. Expansion joint material of one-half-inch thickness shall also be placed
wherever the new work abuts walks, drives or other fixed objects. All of the
sidewalk shall be cut into five feet by five feet flags or squares by one
inch deep dummy grooves. Each dummy groove shall be finished with a steel
edging tool producing the required depth and a smooth finish on each side
of the groove having a width of between one inch and three inches. A finishing
tool shall also be used along the entire length of the walk, parallel to the
street. It too, shall have a rounded edge with a finished top surface of approximately
four inches. Contraction joints shall be made by saw cutting the finished
sidewalk at not more than two flag intervals, and the saw cut shall be at
least three inches deep. One-eighth-inch steel plates may be placed at the
proposed contraction joint locations, and then pulled prior to the use of
the finishing tool, in lieu of saw cutting the joint.
At places where the walk is required to be six inches
thick, it shall be reinforced with 6X6X6X6 welded fabric, set so as to be
two inches below the finished surface. Either standard chairs or brick shall
be used to raise the wire. The fabric need not be epoxy coated. The fabric
shall always be placed sufficiently wide so as to extend at least one foot
on each side of the present driveway leading to the garage.
All sidewalk shall be constructed with a monolithic pour
with either wood or steel forms set to provide for drainage away from the
residence toward the street. One-fourth-inch per foot is desired, but may
not always be possible. Whenever possible this condition shall be maintained,
and each intersecting walk or drive will be matched to avoid the creation
of low points.
Concrete used shall show a minimum twenty-eight-day compressive
strength of at least 4,000 psi. Test cylinders will be taken by the Engineer.
All sidewalks shall be finished by screeding with a light weight type hand
screed which will push the surplus concrete ahead of it. A wooden float shall
then be used to insure that no depressions or high spots exist in the finished
product, and the final finish shall be made by brooming perpendicular to the
line of the street, producing a very lightly roughened surface. If low temperatures
are expected protective measures acceptable to the Engineer shall be taken.
Whenever possible, pours shall be scheduled in the morning.
Barricades, ribbons, cones and blinking lights shall
be used to seal off pedestrian traffic from the work site, and to prevent
vehicles from using the driveway aprons, except as a place to park. A four-foot-by-eight-foot
sign shall be placed at each end of the project work site advising pedestrians
that the walk is not in use, and to please use the walk on the opposite side
of the street whenever one exists.
All aggregates used shall consist of gravel, not crushed
stone. Both the fine aggregate and the coarse aggregate shall meet the specifications
of the Nassau County Department of Public Works 1964 Standard Specifications
for gravel, either crushed or screened, or the New York State Department of
Transportation Specification 703-01 or 703-02, 1982.
The contractor shall protect the sidewalk; keep it true
to alignment and grade and in first class condition until the completion of
the contract. The sidewalk shall also be protected against imprints or markings
in the surface. Any sidewalk which is damaged at any time prior to the final
acceptance of the work, or which is deemed to be unsatisfactory, shall be
removed and replaced at the contractors expense.
In general, all standard specifications for concrete
driveway aprons and concrete sidewalks as set forth in the NCDPW Standard
Specifications shall apply.
Section B - Materials Specifications as they refer to
portland cement and fine and coarse aggregate will be applicable except that
4,000 psi concrete, not 3,500 psi concrete, must be supplied and coarse aggregate
shall consist only of crushed gravel -- no crushed stone or slag.
Item 27 and Item 28 - Cement Concrete Sidewalk
and Cement Concrete Driveways and Driveway Aprons (see copies attached[1]) shall apply except as stated above.
