SUBMITTALS: IN ACCORDANCE WITH REQUIREMENTS OF
GENERAL SPECIFICATIONS, SUBMIT THE FOLLOWING:

Six sets of manufacturer's literature of the materials of this section shall be submitted to
the Engineer for review.

PART 2 - PRODUCTS

2.01

MATERIALS:

PVC non-pressure sewer pipe 4-inches through 15-inches diameter shall conform to
ASTM -_ D3 034, 18-inches through 27-inches diameter to ASTM F679, all with SDR of 3 5
unless noted, and shall meet the specific requirements and exceptions to the aforementioned
specifications which follow.

PVC non-pressure sewer pipe shall be furnished in standard lengths.

One pipe bell consisting of an integral wall section with a solid cross section rubber ring,
factory assembled, shall be furnished with each standard, random and short length of pipe.
Rubber rings shall be provided to the requirements of ASTM D3212.

The rubber ring shall be retained within the bell of the pipe by a precision formed groove
or recess designed to resist fish-mouthing or creeping during assembly of joints.

Spigot pipe ends shall be supplied with bevels from the manufacturer to ensure proper
insertion. Each spigot end shall have an "assembly stripe" imprinted thereon to which the
bell end of the mated pipe will extend upon proper jointing of the two pipes.

PVC fittings shall be provided with bell and/or spigot configurations with rubber gasketed
joints compatible with that of the pipe. Bend fittings with spigot ends shorter than the pipe
recess bells will not be allowed. The shorter spigot end would not allow proper seating of
the spigot in the mating bell and would permit undesired contact between the mating bell
and the outside of the fitting bell.

All pipe delivered to the job site shall be accompanied by independent testing laboratory
reports certifying that the pipe and fittings conform to the above-mentioned specifications.
In addition, the pipe shall be subject to thorough inspection and tests, the right being
reserved for the Engineer to apply such of the tests specified as he may from time to time
deem necessary.

H. All cutting of pipe shall be done with a machine suitable for cutting PVC pipe. Cut ends shall

be beveled when recommended by the pipe manufacturer.

PART 3 - EXECUTION

3.01

INSTALLATION:

Except as modified herein, installation of the PVC pipe shall be in accordance with
ASTM D2321.

Each pipe length shall be inspected before being laid to verify that tt is not cracked. Pipe shall
be laid to conform to the lines and grades indicated on the drawings or given by the Engineer.
Each pipe shall be so laid as to form a close joint with the next adjoining pipe and bring
the inverts continuously to the required grade.

The pipe shall be supported by compacted crushed stone. Crushed stone shall be as
specified under Section 02300, EARTHWORK.

The pipe shall not be driven down to grade by striking tt with a shovel handle, timber, rammer,
or other unyielding object. When each pipe has been properly bedded, enough of the
backfill material shall be placed and compacted between the pipe and the sides of the trench
to hold the pipe in correct alignment.

Before a joint 1s made, the pipe shall be checked to assure that a close joint with the
next adjoining pipe has been maintained and that inverts are matched and conform to the
required line and grade.

For pipe placed on crushed stone, immediately after the joint 1s made, the jointing area shall
be filled with suitable materials so placed and compacted that the ends of either pipe will not
settle under backfill load.

No pipe or fitting shall be permanently supported on saddles, blocking, or stones.

Branches and fittings shall be laid by the Contractor as indicated on the drawings, and/or
as directed by the Engineer. Open ends of pipe and branches shall be closed with PVC caps
secured in place with pre-molded gasket joints or as directed by the Engineer.

All pipe joints shall be made as nearly watertight as practicable. There shall be no
visible leakage at the joints and there shall be no sand, silt, clay, or soil of any description
entering the pipeline at the joints. Where there is evidence of water or soil entering the
pipeline, connecting pipes, or structures, the defects shall be repaired to the satisfaction of
the Engineer.

The Contractor shall build a tight bulkhead in the pipeline where new work enters an
existing sewer. This bulkhead shall remain in place until its removal is authorized by the
Engineer.

Care shall be taken to prevent earth, water, and other materials from entering the pipe, and

when pipe laying operations are suspended, the Contractor shall maintain a suitable stopper
in the end of the pipe and also at openings for manholes.

02085-3

L. — As soon as possible after the pipe and manholes are completed on any street, the Contractor
shall flush out the new pipeline using a rubber ball ahead of the water, and none of the
flushing water or debris shall be permitted to enter any existing sewer.

3.02 QUALITY ASSURANCE
A. CLEANING, INSPECTION, AND TESTING:

1. On completion of a section of sewer, the Contractor shall TV inspect the main section in
accordance with Section 02441, Cleaning, Television Inspection, and Testing of
New Pipelines at no additional cost to the Owner.

2. The Contractor shall be responsible for the satisfactory water-tightness of the entire
section of the sewer. Should the Engineer determine that the sections inspected are not
satisfactory, the Contractor shall be required to excavate and replace the entire
section, at no additional cost to the Owner.

B. PIPE DEFLECTION MEASUREMENT:

1. In accordance with ASTM D3034, no less than 30 days after completion of the PVC
sewer pipe installation, the Contractor shall test the pipeline for deflection using a
"go/no-go" deflection mandrel having a minimum of nine evenly spaced arms
or prongs. The "go/no-go" gauge shall be hand pulled through all sections of
the pipeline by the Contractor. The Contractor shall submit drawings of the "go/no-
go" gauge to the Engineer for approval prior to testing. Complete dimensions of the
gauge for each diameter of pipe to be tested shall be in accordance with ASTM
D3034.

2. Any section of pipe found to exceed 7.5 percent deflection shall be deemed a failed
pipe and shall be excavated and replaced by the Contractor at his own expense.

SECTION 02111

REMOVAL OF UNDOCUMENTED ASBESTOS FROM UNDERGROUND UTILITIES

PART 1 GENERAL
1.01 SCOPE OF WORK

THE CONTRACTOR IS ADVISED THAT DEFINITIONS USED HEREIN MAY BE
MORE STRINGENT THAN REGULATORY AND OR INDUSTRY STANDARD.
IT IS THE CONTRACTOR'S RESPONSIBILITY TO CAREFULLY REVIEW ALL
PORTIONS OF THE SPECIFICATIONS TO PROPERLY EXECUTE THE WORK.

A. This Section specifies the requirements for the removal and disposal of asbestos-
containing materials (ACM) that are not otherwise identified in the Contract Documents
and are discovered during demolition, trenching or excavating operations at the Work
Site. The Work includes, but is not limited to, the removal of the following Asbestos-
Containing Materials:

Asbestos Cement Pipe or Duct

Asbestos (Friable or Non Friable) Encased in Concrete
Asbestos Insulated Electrical Cable

Asbestos Insulated Pipe or Pipe Fittings

Baghouse Materials

B. The intent of the Work is to completely remove and dispose of all undocumented ACM
to permit the demolition of structures and/or trenching or excavation activities. It 1s the
Contractor’s responsibility to determine the most efficient method to perform this work.

This specification does not dictate any specific methods to be implemented in the
performance of the Work. All ACM shall be removed inclusive of any substrate
contamination, whether present on the substrate surface or embedded in the matrix of the
substrate component. After abatement is complete, no detectable asbestos shall remain
within the work area.

C. Should asbestos cement pipe (ACP) or small quantities of asbestos be found, the City
may remove that material using qualified personnel from the Solid Waste Department.
The Contractor will assist with the removal process by removing as much material as
possible around the ACP or small quantities of material found, provide a trench box to
permit safe conditions for the City personnel to remove the material. The Contractor
should immediately notify the Engineer who will make arrangements with the Solid
Waste Department for the removal of this material.

O2111-1

The Contractor shall retain the services of an Asbestos Abatement Contractor to respond
to the unexpected discovery of ACM within the Contract Limits. The Asbestos
Abatement Contractor shall perform removal and disposal in accordance with the
Contractor's work schedule unless the condition of the asbestos-containing material
presents a hazard to the general public or the environment in which case the Asbestos
Abatement Contractor shall perform removal within 24 hours of identification of said
condition. The Engineer will be responsible for making this determination. The
Asbestos Abatement Contractor shall have a current State of New Hampshire Abatement
Contractor's License and meet other qualification requirements specified.

All asbestos removal Work is to be performed in accordance with these Specifications,
Environmental Protection Agency (EPA), Occupational Safety and Health
Administration (OSHA), Department of Transportation (DOT), National Institute of
Occupational Safety and Health (NIOSH), New Hampshire Department of
Environmental Services and other state and local regulations. Wherever there is a
conflict or overlap of the above references, the most stringent provisions apply (see
Subsection 1.07 for specific requirements).

It is not unusual for the Contractor to discover unidentified ACM during construction. It
is within the Contractor's scope of Work to abate the unidentified ACM. Payment for
the removal and disposal of unidentified ACM shall be as described in SECTION 01270
MEASUREMENT AND PAYMENT.

Upon initial discovery or impact of suspect ACM, the Contractor shall immediately stop
any work that may disturb the suspect ACM and notify the Engineer. The Contractor
shall also cordon off the area, cover the suspect ACM with 6-mil polyethylene sheeting,
and await further directions from the Engineer. Suspect ACM that may be impacted by
the Work include, but are not limited to the following: pipe insulation (except for
fiberglass, rubber or foam), concrete duct banks that may contain cement asbestos pipes
and cloth wrapping or insulation on electrical cable.

The Engineer will collect and analyze a representative sample(s) of the suspect material
to determine if it contains asbestos. If the suspect material is confirmed to contain
asbestos, the Engineer will direct the Contractor to proceed with the asbestos abatement

in accordance with the Contract Documents.

Asa description of the general scope of Work, the Asbestos Abatement Contractor shall
provide as a minimum, the following services:

1. Hand excavate an area around the ACM as needed.

2. Remove all ACM and substrate piping from the work area, according to the
procedures detailed in this Section.

3. Thoroughly clean each work area.
