manufacturer of the lining material and any deviation from the
application and/or quality requirements shall be corrected by the
applicator. All inspections shall be in writing and a permanent
record maintained.
(vii) Lining
(1) Upon completion of the blast cleaning operation, the lining material
should be applied to the interior of the pipe within 12 hours in order
to avoid any possible post blast surface contamination. Any area
found to have rust bloom prior to application must be reblasted.
(2) Where field touch up is required to seal cut ends and repair damaged
areas, Joint Compound shall be applied by brush to ensure complete
coverage in accordance with the manufacturer’s recommendations. Joint
Compound may be used over lined pipe and fittings, or on bare substrate.
Care must be taken that the joint compound is applied smooth, without
excessive buildup in the gasket seat or on the spigot ends and allowed to
cure for 24 hours in accordance with the manufacturer’s
recommendations. At least 1-inch of overlap shall be applied to the area
being repaired. The ceramic-filled amine-cured novalac epoxy lining
Protecto 401 shall not be applied over Protecto 401 Joint Compound.
Joint Compound shall not be applied over wet or frozen surfaces.
(viii) Factory Inspection and Certification
(1) The lining in each joint of pipe and fittings shall be tested for pin
holes and pass a non-destructive 2,500-volt pin hole/holiday test. The
pin hole/holiday detection testing shall be conducted over 100% of all

Proposed Revision:Add the following note as extracted from the VDOT CG-2 Parkway Curb Detail: “The depth of the curb may be reduced as much as 3” (15” Depth) or increased as much 3” (21” depth) in order that the bottom of curbwill coincide with the top of a pavement substructure. Otherwise, the depth is to be 18” as shown. No adjustment in the price bid is to be made for a decrease or an increase in depth.”
Reason for Revision:This will allow the use of slip-form machinery (Curb Machine). The current CI_03 detail can only be accomplished with hand forms. This means that sometimes we have to ask the architect or engineer to allow a substitution with the VDOT CG-2, which is essentially the same detail as CI_03, except for the provision for slip-forming.

SECTION 815
PIPE BURSTING
I. GENERAL
1.1 DESCRIPTION OF WORK
The Work covered in this section specifies the method or process to include all labor, materials, tools,
equipment and incidentals necessary to provide for the complete rehabilitation of deteriorated sanitary
gravity sewer by pipe bursting, connect new pipe to existing manholes, modify existing manholes bases as
needed, reconnect existing sewer lateral connections, perform pre- and post-rehabilitation television
inspection, and other Work as shown in the Contract Documents and as specified herein..
Pipe bursting is the construction technique of replacing an existing, underground pipe system in situ by
fracturing a pipe and displacing the fragments outwards into the surrounding soil while a new HDPE or
fPVC pipe is drawn in to the annulus left by the expanding operation to replace the old pipe. The process
can be either by pneumatic, hydraulic or static pull methods, using a conically shaped bursting head to
break out the old pipe. The rear of the bursting head is connected to the new pipe, while its front is
connected to a cable or pulling rod. The bursting head and the new pipe are launched from the insertion
pit, and the cable or pulling rod is pulled from the reception pit. The replacement pipe is either pulled or
pushed into the bore. The replacement pipe shall not be greater than 25% larger in diameter than the
existing pipe. Under favorable conditions upsizing to 150% of the existing diameter may be
permitted upon submittal and Owner approval of supporting calculations from the Contractor.
1.2 SUBMITTALS
The Contractor shall provide qualifications to the Owner as evidence of competency and authority to
perform the method of pipe bursting to be utilized and restoration of existing services. The qualifications
and submittals shall include the following:
A. The Contractor shall be trained by the pipe bursting equipment manufacturer in the use of the
equipment for pipe bursting. The Contractor shall submit a letter from the manufacturer stating
that they provided training to contractor staff on the use, operation and maintenance of the
equipment. The Contractor shall hold the Owner and its agents harmless in any legal action
resulting from patent infringement.
B. The Contractor shall be trained by the thermal fusion equipment manufacturer in the use of the
equipment for thermal butt-fusion of high density polyethylene (HDPE) pipe. The butt-fusion
method for pipe jointing shall be carried out in the field by certified operators with prior
experience in fusing HDPE pipe with similar equipment using proper jigs and tools per standard
procedures outlined by the pipe manufacturer. HDPE pipe shall conform to the requirements of
Section 200.
C. All pipe bursting Contractors shall have at least two (2) years continuous experience in pipe
bursting and shall have completed at least three projects in the last five (5) years involving pipe
bursting installations of a combined total of 25,000 feet of pipe bursting experience as a
prequalification for this project. Documentation to substantiate the Contractor’s experience shall
be provided.
June 2016 815 - 6
Proposed Revision 6.3
2. The insertion pit must be large enough to allow the pipe to be inserted without
overstressing the new pipe in bending. Pipe manufacturer’s bending radius limitations
must be adhered to.
3. When the winch and pulling cables are used to pull the bursting tool through the pipe,
place the winch into the reception pit and pull the cable through the existing pipe and
attach to the front of the bursting unit in the insertion pit.
4. When rigid pulling rods are useused, the rods shall be threaded extend from the
reception pit through the existing pipe to the pipe insertion pit and attach to the bursting
head.
C. Bursting Operation
1. The upsizing method shall not cause excessive disruption or heaving to the above ground
terrain or improvements except for at the launching and receiving pits.
2. Upon commencement of the bursting process, pipe insertion shall be continuous and
without interruption from one entry point to another, except as approved by the Owner.
3. Bursting head shall be remotely controlled. The bursting head shall be sized such that the
maximum diameter of the temporary void created by the bursting operation shall not
exceed the maximum outside diameter of the replacement pipe by greater than 20%. The
new sewer shall be installed straight along the centerline of the existing pipeline
following the same line and grade.
4. Due to the presence of existing utilities adjacent to the sewer to be replaced, the pipe
bursting method shall limit vibrations transmitted to the surrounding soils. The peak
velocity shall be limited to 0.5-inches per second.
5. In the event a section of pipe is damaged during the bursting operation, or joint failure
occurs, as evidenced by inspection, visible groundwater inflow, or other observations, the
Contractor shall submit to the Owner for approval his methods for repair or replacement
of the pipe.
6. Winch and Cable Method
a. Bursting of the old pipe shall be performed as a continuous action providing
constant tension to the bursting head when the winch and cable method is used.
b. The Contractor shall provide a system of guide pulleys and bracing at the exit pit
to minimize cable contact with the existing pipeline between the insertion and
reception pits.
c. Trench shoring supports in the insertion pits shall remain completely separate
from the winch boom support system and shall be designed that neither the
winch support cable shall be in contact with therm.
7. Rigid Rod Method
June 2016 815 - 7
Proposed Revision 6.3
When rigid rods are used as a pulling unit, the bursting operation may be temporarily
halted to unthread and remove each rod section from the pit.
8. Continue this process until the bursting head is pulled completely back into the reception
pit.
9. Do not drag the replacement pipe over the ground surface. Pipe shall move over rollers or
slings for insertion and transportation. Pipe ends shall be capped.
10. If any obstruction is encountered that can not be burst through, the Contractor shall
immediately excavate the location of the obstruction to allow the bursting to continue
with the Owner’s approval. This Work shall be performed in accordance with Section
818 – Point Repair by Excavation.
11. If the Contractor damages any existing utility, the Contractor shall immediately inform
the utility owner of the location and the nature of the damage. The Contractor shall allow
the utility owner time to conduct the necessary repairs prior to continuing the bursting
operation. Damages to properly marked utilities will be the financial responsibility of the
Contractor.
12. If surface heave or subsidence occurs, the Contractor shall repair the impacted area(s) to
the satisfaction of VDOT or the locality, as appropriate.
D. Sewer Service Laterals and Reconnections
1. The Contractor shall be responsible for continuity of sanitary sewer service to each
customer connected to the section of sewer being replaced or rehabilitated during the
execution of the work. If sewage backup occurs and enters buildings, the Contractor shall
be fully responsible for clean-up, repair, property damage costs and claims.
2. Existing service connections shall be located before initiating sewer main replacement
operations. Service laterals shall not be reconnected to the new sewer line until
replacement and testing are completed, and not less than 4 hours after completion of the
pipe bursting procedure. If the bursting is done with HDPE pipe, there shall be a
minimum 12- hour relaxation period before permanent lateral reconnection., in
accordance with the manufacturer’s written recommendations. A strain gage shall
be used to verify that pipe strain does not exceed the manufacturer’s
recommendations, unless deemed unnecessary by the Owner. Any services
remaining off line for an extended period of time, or any connections as deemed
necessary by the Owner to protect the customer, shall be bypass pumped until such time
that they can be reconnected.
3. Connection of the new service lateral (ASTM D-3034 SDR 26 PVC Pipe) to the new
sewer main shall be accomplished by use of the watertight compression –fit service
connection. The service connection shall be specifically designed for connection to the
fPVC or HDPE sewer main being installed, and shall be INSERTA TEE as
manufactured by Insert Tee Fittings, Inc., or approved equal.

fabric is required to wrap joints of rigid pipe, the installation shall be in accordance with
302.2.1.E below.
C. Post Installation Inspection of Storm Sewer Pipes and Culverts
In addition to the visual inspection if performed by the Owner during the initial installation of
storm sewer pipes and pipe culverts, a post installation visual/video camera inspection shall be
conducted by the Contractor in accordance with the requirements of this specification and VDOT
VTM 123 on all pipes identified in the Contract Documents as storm sewer pipe and a selected
number of pipe culverts. For the purposes of this Section all pipe installations not identified in
the Contract Documents as storm sewer pipe are considered pipe culverts. Post installation
Inspections shall be performed on straight line and radial installations.
For pipe culverts, a minimum of one pipe installation for each size of each material type utilized
on the project will be randomly selected by the Owner for inspection, however, in no case will the
amount of pipe subject to inspection be less than ten percent of the total contract amount for the
size and material type indicated. Where possible, for all installations in which the pipe or
culvert’s size, orientation, or location permit deflection to be easily visually identified, (as verified
with the Owner) the Contractor may perform visual inspections in lieu of video inspections. If
defects as described herein are noted during the inspection, the Owner may require additional
pipe installations of that size and/or material be inspected. The Contractor shall coordinate and
schedule all post installation inspections so that these are made in the presence of the Owner. The
post installation inspection shall be performed no sooner than 30 days after completion of the pipe
installation and placement of final cover (except for pavement structure). The Contractor shall
issue a report detailing all issues or deficiencies noted during the inspection (including a
remediation plan for each deficiency noted where applicable) no later than 5 days after
completion of the inspection.
While the intent of this requirement is to perform the post installation inspection prior to paving,
project scheduling may dictate that a particular site be paved before the end of the 30 day period.
In such cases, a preliminary inspection of the pipe shall be made, prior to paving over it, to insure
that the pipe has been properly installed and is performing well. Performing such a preliminary
inspection prior to paving will not relieve the Contractor from the requirement to perform the post
installation inspection after the 30 day period.
The Contractor’s inspection report shall identify and address any of the following items observed
during the post installation inspection including identifying any proposed remediation measures
the Contractor plans to perform where applicable. Remediation measures may consist of
repairing or replacing the defective pipe section(s) or a combination of the two where differing
conditions exist within the same run of pipe. Where permitted as an option, remediation methods
for the various installation defects shall be proposed by the Contractor, reviewed with the Owner
and must have the Owner’s approval prior to implementation of the corrective action.
Remediation shall be the sole responsibility of the Contractor. Further, if remediation measures
are shown to be necessary, any time associated with such measures shall be reflected in the
impact to the Contractor’s progress schedule (may take the form of a time impact analysis, where
required by the scheduling requirements) and will not relieve the Contractor of his responsibilities
to finish the work required by the contract within the contract time limits or form the basis for any
claim of delay where such remediation measures are determined to be a result of the Contractor’s
fault, omission or negligence.
