Contractor shall repair leaks at the interface of the sewer manholes and the liner. Contractor
shall cut the cured liner flush with the inside wall of the manholes after the liner has cooled in
accordance with manufacturer's recommendations. Contractor shall fill voids between
manhole channel, bench, or wall and the liner with quick setting, H2S resistant epoxy mortar
to form a watertight seal. Contractor shall trowel the grout to form a smooth transition
between manhole base or channel and the liner to ensure smooth sewage flow with no
collection points for solids.
9. Reinstatement of Sewer Service Connections
The exact location and number of service connections shall be determined from the CCTV
tape. Contractor shall accurately field locate all existing service connections whether in
service or not. The Contractor shall reconnect all service connections to the liner pipe
including those from unoccupied, abandoned or vacant lot, unless directed otherwise by the
Owner. All existing service connections shall be reconnected by internal remote cutting
method as described below:
a Service Connection by Remote Cut
Service connections shall be performed by a TV-controlled remote cutting device.
They shall be made by experienced operators so that no blind attempts or holes are
made in the liner pipe. Location shall be verified carefully with earlier tapes for
accuracy, especially where dimples are not defined or clearly ascertained. The
Owner reserves the right to require service connection by excavation at certain or all
locations, at no additional cost to the Owner, if the quality, workmanship, and
approval rating for remote cut is poor and not satisfactory.
The remote cut shall be brushed smooth and circular in nature as seen by a 360
degree TV camera. The hole shall be 100% of the service pipe diameter. It shall be
properly aligned and be concentric to the existing connection. The locations of all
remote cuts shall be verified carefully to match earlier tapes for their exact locations.
All wrong holes, or trial cuts shall be considered unacceptable and shall be properly
repaired at no additional cost to the Owner. Excess resin build up is unacceptable
and shall be removed. The Owner's staff shall review all service connections. The
Owner may check the completed remote connections for the 100% requirement by
excavating the site, if necessary. Defective connections shall be properly repaired at
no additional cost to the Owner.
b. Service Connection Insert
All service lateral connections along a mainline to be CIPP lined shall receive a
lateral connection sealing and repair product after installation of the mainline liner,
unless the lateral has been recently replaced by a point repair or remove and
replacement resulting in a new connection. After suitable cleaning and video
inspection, introduce the fiberglass lateral connection sealing and repair product (top
hat) from the mainline into the lateral as follows:
i. A flexible resin impregnated top hat tube that is sized to the service laterals will be
inserted into the service lateral by means of a robotic manipulator device. The
robotic device, together with a television camera, will be used to align the repair
product with the service lateral connection opening. Air pressure, supplied to the
applicator through an air hose, shall be used to insert the top hat into the service
lateral pipe. The insertion pressure will be adjusted to fully deploy the top hat into
the service lateral connection and hold it tight to the main and lateral pipe walls.
Curing of the resin will be through ultraviolet (UV) light, heat or ambient methods
per the manufacturer's specifications.
ii. A resin-impregnated sample shall be retained by the installer for each installation
to provide verification of the curing process taking place in the host pipe. This
sample shall be hung in the entry manhole to simulate arnb.int conditions of the
host pipe.
iii. The inserted product will be inspected using a CCTV camera to confirm the
product is correctly positioned and/or centered in the lateral opening prior to
curing.
iv. The pressure apparatus shall include a bladder of sufficient length in both the
main and service lateral lines to extend beyond the ends of both the lateral tube
and main line brim segments. A smooth transition from top hat to the pipe
diameters without a step, ridge or gap between the product and the inner
diameters of the service lateral and mainline host pipes must be achieved.
v. After insertion is completed, the manufacturer's recommended pressure must be
maintained on the impregnated product for the duration of the curing process. The
liner is chemically cured with UV light or at ambient temperatures or by a suitable
heat source according to the manufactures specification. The heating equipment
shall be capable of delivering a mixture of steam and air throughout the liner
Madder assembly to uniformly raise the temperature above the temperature
required to cure the resin. The curing of the CIPP must take into account the
existing pipe material the resin system, and ground conditions (temperature,
moisture level, and thermal conductivity of the soil). The heat source temperatures
shall be monitored and logged during the cure and cool down cycles. Once the
sample piece in the manhole has cured, the bladder is deflated, removed from
connection and returned to the manhole to repeat the cycle. Contractor shall
recover the sample piece and label with upstream and downstream manhole
numbers and footage from upstream manhole to service connection. Sample shall
be submitted for testing.
vi. The top hat insert laminate shall seal to the inside wall of the mainline a minimum
of 3 inches around the host lateral opening and to the lateral wall 7-24 inches into
the lateral pipe from the main host pipe. Deviation from these dimensions shall be
approved by the Engineer prior to installation. The cured top hat must attain the
cured physical strength of, and chemical resistance of, and provide adequate
adhesion to the pipeline liner.
vii. The Contractor shall install the top hat into the service lateral connection within
five (5) days of the main line CIPP liner installation.
In extreme circumstances, Contractor may have to reinstate a sewer service
connection by excavation, if approved and at no additional cost to Owner as
described below:
Service Connection by Excavation (In Case of Emergency Only)
If reinstatement of a sewer service connection cannot be completed with a
robotically-controlled device from within the sewer main, the service connection shall
be excavated at the exact location where the existing lateral connects to the main.
The existing lateral shall be disconnected from the sewer main. The existing sewer
main (carrier pipe for the liner), shall be carefully broken removed to expose the liner
to the extent necessary. The liner pipe shall not be damaged and shall be allowed to
normalize to ambient temperature and cool down before a hole is drilled out. This
coupon shall be retrieved and delivered to the Owner for inspection of the liner
thickness at that location. The cut out hole section in the liner shall be coated with
approved resin epoxy which shall cure at the ambient temperature.
A pre-fabricated polyethylene saddle or approved equal fitting shall be installed over
the cut out. The saddle shall be a one-piece saddle equipped with a neoprene gasket
so that a complete seal is accomplished when the strap-on saddle is tightened with
two (2) stainless steel bands, one on each side. The stub-out attached to the saddle
must protrude into the liner a distance equal to the wall thickness of the liner. The
new stub out or lateral shall be connected to the existing service line by a rubber
coupling with stainless steel bands, as manufactured by "Mission" or an Owner
approved equal.
The "Mission" coupling shall be secured to the existing service lateral and new stub
and / or stack with stainless steel bands. The entire exposed service connection shall
be encased in cement-stabilized sand a minimum of 6" below and 12" above and on
the sides of the pipe at a cost incidental to service connection. The service
connections shall be tested by the Contractor and approved by the Owner before
backfilling.
Gasketed PVC sewer pipe (Schedule 40) may be used for all stubs. PVC saddles
with neoprene gaskets may be used in lieu of polyethylene saddles.
A service reconnection by excavation shall consist of the removal and replacement of
any cracked, offset, or leaking existing service line up to a distance of eight (8) feet
from the center of the new liner measured horizontally.
If reinstatement of a sewer lateral service connection requires open trench
construction, the amounts bid by Contractor shall include all costs for all materials,
equipment, and labor unless separate bid items are included in the bid sheets to
complete the work, all at no additional cost to the City.
Said amounts shall include, but not be limited to, utility location and verification
(excavating, exposing, and verifying top, bottom, and side of utility crossings),
removing, disposing, and replacement of existing sewer pipe materials, relocation of
existing utilities as required for construction, trenching, excavating and exporting
unsuitable material, exporting and importing trench material and acquiring location to
stockpile trench material (if space is not available onsite), dewatering, shoring or
sloping (as required), bedding (including imported select material or select native
material), furnishing and installing all other materials, backfilling (including imported
select material or select native material), compacting, testing, protecting in place or
removing and replacing all existing utilities, and public and private improvements
(including berms, curbs, gutters, sidewalks, cross-gutters, spandrels, medians,
driveways, landscaping, landscaping materials, irrigation systems, fencing, walls,
power poles, poles, signs, and guard rails), restoring all areas and improvements to
pre-existing improvements, in accordance with the Contract Documents.
10 Post-Lining Inspection of Mainline (see PART 6 herein)
11 Field Testing and Acceptance (see PART 6 herein)
B Liner Installation (General)
Installation of the impregnated liner may be by inversion or insertion as specified by the
manufacturer. All equipment, labor, materials, and processes required to complete the work must be
ready on-site before installation begins.
The first segment shall be lined, completed and accepted to become the "job standard" against
which all subsequent work is judged.
C Liner Installation Setup
The installation area/equipment shall be securely protected and all damaged yards, driveways,
walks, etc., shall be repaired at no cost to the Owner. Plastic sheeting will be used to cover the work
area around the manholes and/or access points to eliminate the opportunity of environmental
contamination to the aboveground setting during the installation process.
D Preliner/Outer Film/Outer Liner for Felt Products
At all locations where the CIPP felt liner is inverted or inserted into the host pipe, a preliner shall be
used to control resin loss, liner thickness, a reduction in physical properties, of the resin by water or
other contaminants, and prevent blocked or plugged services and laterals. The preliner shall be a
reinforced plastic sheet formed into a tube, sized to fit the host pipe being lined and shall be
continuous from manhole to manhole. Installation of the preliner shall be witnessed by the Owner or
Engineer. Failure to install the required preliner or installation of preliner over only part of the
segment shall result in the completed CIPP for that segment being rejected (regardless of physical
tests and thickness test results). During thickness testing, the preliner shall be removed from the
thickness test core sample along with the inner liner film used. If there is any damage to the preliner,
it should be repaired immediately.
E. Liner Insertion for Fiberglass/UV-Cured Products
1. For fiberglass-based liners, a slip sheet shall be installed on the bottom half of the pipe prior
to liner insertion, for the purpose of smoothing out the bottom of the liner to increase flow
characteristics.
2. Fiberglass-based liners shall have an outer and inner styrene film barrier. The outer film shall
be a UV-resistant barrier. The inner film material should be removed and discarded after
curing to provide optimal quality of the final product.
3. A constant tension winch should be used to pull the glass fiber liner into position in the pipe.
Once inserted, end plugs shall be used to cap each end of the glass fiber liner to prepare for
pressurizing the liner. The end plugs should be secured with straps to prevent them from
being expelled due to pressure. Liner restraints should be used in manholes.
4. The glass fiber liner shall be cured with UV light sources at a constant inner pressure. When
inserting the curing equipment in the liner, care should be taken not to damage the inner film
material.
a. The UV light sources should be assembled according to the manufacturer's
specifications for the liner diameter. For the liner to achieve the required water
tightness and specified mechanical properties, the following parameters must be
controlled during the entire curing process, giving the Engineer a record of the curing
parameters over every segment of the entire length of the liner. This demonstrates
that the entire liner is cured properly. The recording will include:
• Curing speed
• Light source working & wattage
• Inner air pressure
• Exothermic (curing) temperatures
• Date and time
• Length of liner
A record of the curing parameters shall be obtained using a computer and data base
that are tamper proof. During the curing process, infrared sensors shall be used to
record curing data that will be submitted to the Engineer with a post-CCTV inspection
on DVD.
b The parameters for curing speed, inner air pressure and wattage are defined in the
Quality Tracker UV-curing protocol issued by the manufacturer. The optimal curing
speed, or travel speed of the energized UV light sources, is determined for each
length of liner based on liner diameter, liner thickness, and exothermic reaction
temperature.
5. Flushing of the cured fiberglass/UV-cured CIPP liner (to reduce styrene residual) is not
required for fiberglass/UV-cured CIPP products that provide 3rd party test results that
document styrene residual levels (without flushing) within acceptable defined levels.
F. Liner Insertion/Inversion for Felt Steam Cured Products
1 The resin impregnated liner shall be transported and stored in a refrigerated truck until it is
installed in an existing line by using an application of water or cable and winch to properly
place the liner between the upstream and downstream manholes.
2. For felt-based liners, a preliner or outer film in the form of a tube, shall be inserted into the
pipe prior to inserting the impregnated liner.
3. The wet-out felt liner shall be inserted, or inverted, through an existing manhole or other
approved access. Liner installation head pressures (minimum and maximum for hot and cold
conditions) shall not be exceeded, regardless of which method of installation (stand pipe,
pressure unit, etc.) is used.
4. Using the "Inversion Procedure", the liner end shall initially be turned inside out and attached
to a platform ring, standpipe, or as approved. The addition of water will be adjusted to
sufficient height/pressure to cause the impregnated liner to invert from manhole to manhole,
and hold the liner tight against the existing pipe wall.
5. Using the "Insertion Procedure", the liner is winched into position according to
manufacturer's recommendations. The addition of water will be adjusted to sufficient
height/pressure to cause the calibration hose to invert from manhole to manhole and hold the
liner tight against the existing pipe wall.
6. Liner restraints should be used in manholes.
7. CURING WITH STEAM. After the installation of the liner is completed, the Contractor shall
use heat system capable of providing the required amount of heat uniformly throughout the
section for a complete cure of the resin. Steam curing must comply with ASTM F1216.
a. The curing temperature, pressure and schedule shall be as recommended by the
resin/catalyst system manufacturer. Temperature gages shall be installed in the
following areas: incoming steam supply; outgoing steam supply and between the
impregnated tube and the pipe invert at the lining termination point.
b. Cool down shall per manufacture's specification to guarantee required physical
properties. Methods of curing and cool down shall minimize the introduction of
c. tyrene to the wastewater assuring that no detectable levels will enter the downstream
wastewater treatment facility.
G. PARTIAL (POINT REPAIR) C1PP LINERS:
1. The partial CIPP liner shall be installed in accordance with ASTM F 2599 and same
requirements as for a full length liner,
2. The dimensions of the liner shall be fabricated to a size that when installed, will neatly fit the
circumference of the existing conduit. The materials and physical properties of the partial

3. The tube, in good condition, shall be vacuum impregnated with the thermo-set resin. All air in
the tube shall be removed by vacuum allowing resin to thoroughly impregnate the tube. A
resin-impregnated sample shall be retained by the installer for each installation to provide
verification of the curing process taking place in the host pipe. This sample shall be hung in
the entry manhole to simulate ambient conditions of the host pipe.
4. The saturated tube along with the inversion bladder will be inserted into the carrying device
and pulled into the host pipe. The pull is complete when the end of the launching device is
aligned with the beginning of the section to be repaired. The resin and tube shall be
completely protected during the pull such that no resin is lost by contact with manhole walls
or pipe. The resin that provides a structural seal shall not contact the pipe until positioned at
the point of repair.
5. The installer shall be capable of viewing the beginning of the liner contacting the host pipe
verifying the exact placement of the liner. No measuring from a CCTV counter or estimating
will be allowed.
6. The tube will be extracted out of the carrying device by controlled air or water pressure. The
tube is held tightly in place against the wall of the host pipe by the pressure until the cure is
complete.
7. Once the sample piece in the manhole has cured, the inflation bladder is deflated, and
bladder and launching device are removed from the host pipe. Any materials used in the
installation other than the CIPP liner is to be removed from the host pipe by the installer.
Contractor shall recover the sample piece and label with upstream and downstream manhole
numbers and footage from upstream manhole to service connection. Sample shall be
submitted for testing in accordance with PART 6.
8. Any service lateral connections covered by the sectional repair are to be restored in
accordance with PART 5.A.9.

layers with a probe or point of a knife blade so that the layers separate cleanly or the probe or knife
blade moves freely between the layers. If separation of the layers-occurs during testing of field
samples, new samples will be cut from the work. Any reoccurrence may cause rejection of the work.
Testing of the completed, installed liner consists of:
A. Field testing
B. Laboratory testing
The contractor shall provide and pay for all required testing samples herein. The Owner will pay for
all post installation laboratory testing described herein. Retests of failed samples shall be paid for by
the Contractor via a deductive line item on the pay estimate.
Regardless of the resinlcarrier liner system used, the completed liner shall meet or exceed:
A, The initial modulus of elasticity (ASTM D-790) (as stated in design calculations);
B, Initial flexural strength (ASTM D-790);
C, CIPP shall meet the chemical resistance requirements of ASTM F1216, Appendix X2);
and
Values for the three parameters above which are under the minimum values stated on the bid form
are not acceptable. An under thickness liner may be brought into compliance at no additional cost to
the Owner by (1) removal and replacement of the undersized liner, or (2) addition of a second liner
with the full wall thickness as stated on the liner design submittal (and after acceptable preparation
of the undersized liner interior). Option 2 will be considered by the Owner on a case by case basis
considering the resulting loss of flow capacity, and can be refused by the Owner for that reason. The
addition of a thin liner that makes up the amount of undersizing is not an acceptable remedy
because the structural properties of CIPP liners are not additive if they are not cured simultaneously
and therefore are bonded together to act as a single liner.
In the event of a liner failure of either/both the flexural strength and the modulus tests, another flat
plate sample shall be tested. Should the second sample fail, the liner shall be brought into
satisfactory compliance by the above methods.
The Contractor must have performed long-term testing for flexural creep of the CIPP pipe material
installed by his Company. Such testing results are to be used to determine the long-term, time
dependent flexural modulus to be utilized in the product design. This is a performance test of the
materials (Tube and Resin) and general workmanship of the installation and curing as defined within
the relevant ASTM standard. A percentage of the instantaneous flexural modulus value (as
measured by ASTM D790 testing) will be used in design calculations for external buckling. The
percentage, or the long-term creep retention value utilized, will be verified by this testing. Retention
values exceeding 50% of the short-term test results shall not be applied unless substantiated by
qualified third party test data to the Owner's satisfaction. The materials utilized for the contracted
project shall be of a quality equal to or better than the materials used in the long-term test with
respect to the initial flexurai modulus used in the CIPP design.
A Sample Requirements
The following sample shall be taken for each section of sewer lined and shall be included in the bid
cost for this project:
One core of 12" diameter minimum taken from the inside of the pipe or from an 18" long section of
the CIPP (sufficient in length to conduct ASTM flexural test) extending from the existing pipe being
lined in the manhole equal to the exact ID of the lined pipe. See "Non-destructive " option below.
"Non-destructive" option: At Owner's option, in lieu of excavation for core samples, the liner shall
be run through 18" long section of line-sized pipe, or an appropriate restraint, to act as a mold for the
liner and cured. One such sample shall be taken from liner at starting manhole and one at the
ending manhole of the section being lined. One sample from each lined section shall be provided.
B. Field Test (Thickness)
Remove the CiPP liner material from the host pipe core samples. Remove any inner liner film,
preliner and resin that is not contained within the felt liner. Measure the liner thickness at three spots
on each sample. The resulting six measurements will be averaged. The average thickness shall be
equal to or greater than the required thickness for the particular section stated on the bid form. No
undersize allowance is permitted. In accordance with D 740-03, referenced in ASTM 1216, the
calculated wall thickness refers only to the part of the liner that consists of a saturated felt liner.
Elements that are not part of the saturated felt liner do not contribute to the structural integrity of the
liner, thereby excluding felt liner that is not fully saturated or portions of resin without the felt liner
carrier.
If the Contractor takes his sample from inside the line, he must repair the spot with a method
approved by the Engineer.
C. Laboratory Testing
Samples obtained for these tests will be sent by the Owner to an approved laboratory for testing.
The Owner will pay for testing. Contractor will provide samples as part of the contract bid cost. A FRI
scan will be done by the Owner confirm the correct material was used.
D. CCTV Visual Test
The Contractor and Engineer shall inspect each installation visually by CCTV. Variations from the
true line and grade may be inherent because of the condition of the original piping. No infiltration of
groundwater should be observed. All service entrances should be accounted for and be fully
functional unless otherwise directed by the Engineer in writing. No visible leak around liner at
manhole connection will be allowed. Visual inspection shall examine defects including but not limited
to fins, wrinkles, imperfections, areas of uncured resin, or areas of incomplete resin impregnation. A
fin or wrinkle shall be defined as a defect when it penetrates inside the pipe more than 0.25 inch
from the inside wall curvature of the new liner adjacent to the fin or wrinkle. A remedial repair and/or
replacement action plan shall be submitted by the contractor to the Engineer for review and approval
for any defect prior to any corrective action. Failure to obtain the Engineer's approval for corrective
plan may result in rejection of the liner and require a new liner. The pre- and post-installation
documentation in DVD format will become the property of the Owner. CCTV inspection shall be
provided as required in PART 5. A.5 and included as part of the contract cost.
