CURED-IN-PLACE PIPE LINING (CIPP) FOR STORM DRAIN
ULTRAVIOLET LIGHT CURED CIPP
PART 1 GENERAL
1.1 SCOPE
A. Work under this section consists of furnishing all materials, labor, and equipment
required for the installation of cured-in-place pipe (CIPP) in storm drains cured by
ultraviolet (UV) light.
1.2 DESIGN AND PERFORMANCE REQUIREMENTS
A. The CIPP shall be designed for a life of 75 years or greater in accordance with
ASTM F1216, Appendix X.1, for "fully deteriorated gravity pipe conditions."
The Bid Form and/or Drawings may list alternate minimum required thicknesses
for installation based on the Engineer's decision for specific installations and may
list specific thicknesses for larger diameter storm drains.
Each CIPP shall be designed to withstand internal and/or external loads as
dictated by the site and pipe conditions. Unless listed by the Engineer on the Bid
Form and/or Drawings, the required installed thickness of the CIPP shall be
derived using the standard engineering methodology as found in ASTM F1216,
Appendix X1. In no case shall the installed thickness be less than 3 mm. The
thickness calculations shall be submitted to the Engineer prior to CIPP
installation. The designs shall include a step-by-step calculation that shows all
equations, defines all variables, lists all assumptions, and clearly indicates all
values used for the design.
B. The layers of the finished CIPP shall be uniformly bonded. It shall not be
possible to separate any two layers with a probe or point of a knife blade so that
the layers separate cleanly or such that the knife blade moves freely between the
layers. If separation of the layers occurs during testing of the field samples, new
samples will be cut from the work. Any reoccurrence may be cause for rejection
of the work.
C. The structural CIPP wall thickness design for this Project is being based on the
design criteria listed below, which reflects typical physical properties of Saertex
Liner by Saertex Multicom. The wall thickness calculations are also in
accordance with ASTM F2019-20 and the design equations in Appendix X1 of
ASTM F1216. The minimum wall thicknesses presented herein for the various
depths are based on Saertex and shall be considered the minimum wall
thicknesses for each depth category.
Page 1

For any products other than Saertex, the Contractor shall submit detailed product
information and test results to document the physical properties of the proposed
liner. The tests results shall include certified 20,000 hour test results to document
the long-term creep factors to be used in the design calculations. The Contractor
shall also submit design calculations from the proposed liner manufacturer which
are based on the proposed product's documented physical properties. The liner
thicknesses for installation shall be adjusted (as required by the calculations) to
the various specified depths based on the proposed product's physical properties
and the design calculations submitted. Under no circumstance shall the installed
liner be thinner than specified herein for the various depths of storm drain,
regardless of the submitted calculations. Payment will be made for the installed
CIPP based on the depth of installation.
Design Safety Factor 2.0
Short-Term Flexural Modulus 2,800,000 psi
Short-Term Flexural Strength 39,000 psi
Creep Retention Factor 75% (based on 20,000 hour tests)
Ovality 2%
Soil Modulus 1,000 psi
Soil Density 120 pounds per cubic foot
Soil Coefficient of Friction 0.130 r
Groundwater Depth Ground Surface Elevation unless
otherwise noted
Live Load H20 Highway
Poisson's Ratio 0.3
Enhancement Factor, K 7
Service Temperature Range 40 to 140 degrees F
Maximum Long-Term Deflection 5 percent
NOTE: A modification to the soil modulus may be considered for storm
drains with more than 30 feet of cover as approved or specified by the
Engineer. In addition, where other data exists for ovality or other
parameters, the required structural CIPP wall thickness shall be based on
the more stringent parameters unless otherwise approved or specified by
the Engineer.
Based on the above Saertex physical properties, the minimum installed, cured
liner thicknesses per various depths shall be as listed below. The Bid Form
and/or Drawings may list alternate thicknesses for installation based on the
Engineer's decision for specific installations.

Any additional/mixing of fillers and catalysts to the resin shall be performed at the wet-out
facility and not at any intermediary mixing facility unless approved otherwise by the
Engineer. Copies of the shipment documents from the resin manufacturer shall be
submitted to the Engineer showing dates of shipment, the originating location and the
receiving location. The Contractor shall submit a Certificate of Authenticity from the resin
manufacturer for each shipment to the wet-out facility (to include the date of manufacture).
This information shall be submitted prior to manufacturing any CIPP.
R. The Contractor shall identify the wet-out facility where all CIPP under this Contract will
be manufactured. All CIPP shall be manufactured from this designated wet-out facility
throughout the entire Contract unless specifically approved otherwise by the Engineer in
writing. Multiple wet-out facilities shall not be allowed.
S. The Engineer, Owner and/or an agent of the Owner may inspect the CIPP during
manufacturing (during "wet-out"). The Contractor shall submit UV wetout schedules so
that an agent of the Owner may inspect the CIPP manufacturing process. The Contractor
shall submit a schedule for manufacturing the CIPP to the Engineer every Friday for the
