Areas. Restoration of stabilized areas shall be completed as detailed
on the drawings and as set forth in the contract documents. The contractor
is to understand that since the pipe trenches under stabilized areas
will be backfilled with PennDOT 2RC select granular material, there
will be no payment for restoration of stabilized areas. Contractor
shall grade, shape and compact the full width of the stabilized roadway
and all other stabilized areas.

Prior
to placing the bituminous concrete overlay pavement, apply a bituminous
tack coat consisting of a thin application of emulsified asphalt at
such rate and in such manner as set forth in PennDOT Publication 408
Specifications, Section 460.
7.
The
contractor shall adjust existing shoulders, driveways, street approaches,
accesses, businesses, parking areas, etc., to conform to the finished
pavement elevation. This work will be considered incidental to the
placement of the bituminous wearing course and will not be paid for
separately.
8.
Restoration
of driveways, street approaches, sidewalks, parking areas, curbs,
curb gutters, etc., shall be replaced "IN KIND," in accordance with
PennDOT Standards or as detailed on the drawings and in the contract
documents. As a minimum, concrete pavement restoration shall be six
inches thick with six by 6 4/4 welded wire fabric reinforcing,
and bituminous concrete pavement restoration shall be four inches
thick, after proper compaction, PennDOT bituminous concrete base course
with a one-inch-thick, after proper compaction, PennDOT bituminous
wearing course ID-2, SRL-L. Cement concrete curb and cement concrete
curb gutter shall be replaced to the same shame, thickness, workmanship
and finish as the original curb or curb gutter unless otherwise required
by the Township.
9.
All
pipe trenches under bituminous concrete surfaces and stabilized surfaces
shall be backfilled with PennDOT 2RC select granular material. The
contractor is to understand that payment for this backfill material
will not be made directly but will be considered incidental and subsidiary
obligations to the other pay items as set forth in the contract form
of proposal.
10.
Prior
to the placement of the permanent pavement, the existing pavement
must be concrete saw cut in a neat, straight line, to the bottom elevation
of the existing base course, one foot on each side of the trench removed,
or the existing pavement shall be removed to the edge of the existing
pavement, if so directed by the Township Engineer. No separate payment
will be made under this project for removing existing pavement. The
contractor must adjust all necessary storm inlets of the Pennsylvania
Department of Transportation, Township of Logan and City of Altoona
and shall be responsible to coordinate (and bear the cost of, if required)
the adjustment of all private and public utilities (valve boxes, curb
boxes, manhole covers and cleaned covers) to conform to the finished
pavement elevation. No separate payment will be made under this project
for adjusting the height of storm inlets and utility boxes.
11.
All
joints between the new pavement and existing pavement, between curbs
(curb gutters) and new pavement and around storm inlets, valve boxes,
curb boxes, manhole covers and cleaned covers shall be sealed with
a hot bituminous material of the class and type designated for the
wearing course. The hot bituminous material shall have a minimum width
of 12 inches at the joints and shall extend 12 inches from the curb
(curb gutters), storm inlets, valve boxes, curb boxes, manhole covers
and cleanout covers. Prior to sealing, clean and free harmful material
from the area to be sealed.
12.
The
contractor shall perform temporary restoration of trenched areas immediately
upon satisfactory completion of laying and backfilling of the sewer
pipe in order to return all roadways to a condition that will permit
safe, free and unobstructed movement of vehicular and pedestrian traffic.
Failure of the contractor to comply with this requirement will constitute
sufficient cause of the Township to order an immediate stoppage of
all construction work until trench restoration requirements are completed
to the satisfaction of the Township.
13.
Dust
Control. The contractor shall provide effective dust control during
the entire project. Dust control shall be accomplished by the use
of water or calcium chloride or by other methods approved by the Township.
The contractor shall be required to make the connections between
existing sewer laterals, sewer mains and manholes owned by the Township
or any other municipal entity. The construction of each connection
shall be completed in strict conformance with the drawings and the
requirements of the applicable public entity. The contractor shall
furnish all pipe, fittings, couplings, adapters and other materials
necessary to make the connections. The contractor shall take all necessary
precautions and provide the necessary plant, labor, materials, and
equipment to prevent interruption of the flow in the existing sewers.
The contractor shall be responsible for and shall correct, to the
satisfaction of the public entity and the owner, any and all damages
to the existing manhole sewage treatment plant and sewer lines caused
by the contractor's operations. All pipe and fittings shall be as
specified herein for sanitary sewer pipe and laterals.
When required by Chapter 18 of the Logan Township Code of Ordinances, the installation of a water meter upon the portable water sources must meet the Altoona Water Authority Specifications as amended from time to time.
Prior to final acceptance of any sanitary sewer extension by
the Township, the developer shall furnish to the Township "as-built
plans" showing the angle and distance between manholes, the top and
invert elevation of each manhole and the exact location of all sewer
lateral connections relative to the nearest manhole both downstream
and upstream, including the depth at lateral end.
