In addition to the afore mentioned, the owner may require that the contractor demonstrate that the enhancements proposed exceed the specifications herein, prior to the installation of the enhanced material systems. This section shall no way be interpreted as authorization to deviate from the minimum standard practices set forth herein. Documentation for products and installers seeking pre-approved status must be submitted no less than two weeks prior to proposal due date to allow time for adequate consideration. The Owner will advise of acceptance or rejection a minimum of three days prior to the due date. All required submittals must be satisfactory to the owner. Materials The sewn tube shall consist of one or more layers of absorbent non-woven felt fabric and meet the requirements of ASTM F1216, Section 5.1 or ASTM F1743, Section 5.2.1, or ASTM D5813, sections 5 and 6. The tube shall be constructed to with stand installation pressures, have sufficient strength to bridge missing pipe, and stretch to fit irregular pipe sections. The wet out tube shall have a relatively uniform thickness that when compressed at installation pressures will equal or exceed the calculated minimum design CIPP wall thickness. The tube shall be manufactured to a size that when installed will fit the internal circumference and length of the original pipe. Allowance should be made for circumferential stretching during installation. The outside layer of the tube shall be 2 ---PAGE BREAK--- coated with an impermeable, flexible, membrane that will contain the resin and allow the resin impregnation (wet out) procedure to be monitored. The tube shall contain no intermediate or encapsulated elastomeric layers. No material shall be included in the tube that may cause delamination in the cured CIPP. No dry or unsaturated layers shall be evident. The wall color of the interior pipe surface of CIPP after installation shall be a relatively light reflective color so that a clear detailed examination with closed circuit television inspection equipment may be made. Seams in the tube shall be stronger than the non-seamed felt material. The tube shall be marked for distance at regular intervals along its entire length in increments not to exceed 5 feet. Such markings shall include the manufacturers name or identifying symbol The tubes shall be manufactured in the USA. The resin system shall be a corrosion resistant polyester or vinyl ester system including all required initiators that when cured within the tube create a composite that satisfies the requirements of ASTM F1216. ASTM D5813, and ASTM F1743, the physical properties herein, and those which are to be utilized in the submitted and approved design of the CIPP for this project. The resin shall produce a CIPP that will comply with the structural and chemical resistance requirements of this specification. Structural Requirements The CIPP shall be designed as per ASTM F1216, Appendix X.1. The CIPP design shall assume no bonding to the original pipe wall. The Contractor must have performed long term testing for the 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 with the relevant ASTM standard. A percentage of the instantaneous fiexural 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 final flexural modulus used in the CIPP design. The Enhancement Factor to be used in “Partially Deteriorated” design conditions shall b assigned a value of 7. The layers of the cured 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 3 ---PAGE BREAK--- cleanly or the probe or knife blade moves freely between the layers. If the layers separate during field sample testing, new samples will be required to be obtained from the installed pipe. Any reoccurrence may cause rejection of the work. The cured pipe material (CIPP) shall conform to the structural properties as listed. The Modulus of Elasticity for the cured polyester composite as per ASTM F 1216 using test method ASTM D790 shall be no less than 250,000 psi. The Modulus of Elasticity for the enhanced resin using testing method ASTM D790 will be no less than 400,000 psi. The flexural stress for the cured polyester composite as per ASTM F1216 using testing method ASTM D790 will be no less than 4,500 psi. The flexural stress of the enhanced resin using testing method ASTM D790 will be no less than 4,500 psi. The required structural CIPP wall thickness shall be based as a minimum, on the physical properties of ASTM F1216, Section 5.5 or greater values if substantiated by independent lab testing and in accordance with design equations in ASTM F1216, Appendix Xl. Design considerations for this project will be ASTM F1216 and the following parameters: Design Safety Factor (typically used value) 2.0 Retention factor for long term flexural modulus to be used in design 50%-75% As determined by long term tests described in ASTM F121, Section 5.2 and approved by the Owner) Ovality, (calculated from ASTM F1216, Appendix X1.1) % Enhancement Factor, K (see ASTM Fl216, Section 5.3) Groundwater depth (above invert of existing pipe, in ft.) see design plans Soil depth (above crown of existing pipe, in ft) see design plans Soil modulus, in psi (required only for fully deteriorated design conditions) Soil density, in pcf (required only for fully deteriorated design conditions) Live Load (required only for fully deteriorated design conditions) H20 Highway Design Condition (required only for fully deteriorated design conditions) The CIPP shall meet the chemical resistance requirements of ASTM F 1216, Appendix X2. CIPP samples for testing shall be of tube and resin system similar to that proposed for actual construction. It is required that CIPP samples with and without plastic coating meet these chemical testing requirements. Overall, the hydraulic cross section shall be maintained as large as possible. The CIPP shall have a minimum of the full flow capacity of the original pipe before rehabilitation. Calculated capacities may be derived using a commonly accepted roughness coefficient for the existing pipe material taking into consideration its age and condition. When requested by the Owner, the Contractor shall submit test results from field installations of the same resin system and tube materials as proposed for the actual installation. These test results must verify that the CIPP physical qualities specified in ASTM Fl216, section 5.5, have been achieved in previous field applications. Samples for this project shall be made and tested as described under the section titled Inspection. 4 ---PAGE BREAK--- Installation Responsibilities for Incidental Items It is the responsibility of the Owner to locate and designate all manhole access points open and accessible for the work and provide rights-of-access to these locations.

The total thickness of the multi-component stress panel liner shall be no less than 500 mils. Manhole Inspection The applicator shall take appropriate action to comply with all local, state, and federal regulations including those set forth by OSHA, EPA, the Owner, and any other applicable authorities. Prior to conducting any work, an inspection will be performed on the structures to determine the need for protection against hazardous gases, oxygen depleted atmosphere, and flow control or flow diversion. A plan will be submitted for flow control/bypass as part of the bid documents if required by the installer. Surface Preparation Surface preparation methods may include high pressure water cleaning, hydro blasting, abrasive blasting, grinding, detergent water cleaning, and shall be suited to provide a surface compatible for the installation of the liner system. The selected surface preparation method shall produce a clean, abraded, and sound surface with no evidence of laitance, loose concrete, loose mortar, loose brick, contaminants, or debris and shall produce a surface profile suitable for the application of the liner system. After the surface preparation has been completed, a seven point inspection will be completed covering the following items: leaks, cracks, holes, exposed rebar, ring and cover condition, invert condition, and inlet/outlet pipe condition. Defects found from the inspection will be resolved before the liner is installed. Leaks will be repaired with a chemical or hydraulic sealant designed for use in the field. Severe cracks will be repaired with a urethane based chemical sealant and will be approved for use by the engineer prior to installation. Repairs to exposed rebar, defective pipe/inverts, shall be repaired utilizing a non-shrink grout or an alternate method approved by the engineer. 9 ---PAGE BREAK--- Material Installation Liner application procedures will conform to the recommendations of the manufacturer including materials handling, mixing, environmental controls during application, and safety issues. Application equipment shall be specifically designed to accurately ratio and apply the liner system. Application of the multi-component liner system shall be in strict accordance with the manufacturer’s recommendation. Final installation will result in a thickness of no less than 500 mils. Inspection A permanent label will be affixed to the structure in a visible location containing the manufacturer, installer, and date of installation. Final liner system will be free of pinholes and voids. Liner thickness will be no less than 500 mils. Visual inspection will be made by the Owner or Owner’s representative. Any deficiencies in the finished liner system shall be marked and repaired according to Manufacturer’s recommendations. All repairs to the liner will be inspected by the Owner or the Owner’s representative before acceptance by the Owner. 10 ---PAGE BREAK--- Storm Sewer Lining Supplemental Specifications & Comments September 7, 2012 The purpose of this project is to stop dirt infiltration through the open joints in reinforced concrete storm sewer pipe. The contactor will be required to clean the line before installing the liner. The City will provide a dump location approximately 5 blocks from the installation site. The site is located off the road through the park. The City is not aware of any lines entering the main between the manholes, however, the contractor will be required to video the lines to determine if any such connections exist and to open those connections once the liner has been installed. The line being bid has ground water flowing through it. The contractor will be required to pump the groundwater. The ground water may be reintroduced into the line of the manholes at the terminus of the pipe section being lined. The City will provide traffic control and water for the project. ---PAGE BREAK--- Storm Sewer Lining Supplemental Specifications & Comments September 7, 2012 The purpose of this project is to stop dirt infiltration through the open joints in reinforced concrete storm sewer pipe.
