4. WALL THICKNESS: The wall thickness of the material tube shall be ordered to the next standard 1.0 mm incremental thickness above the minimum calculated design thickness. Unless otherwise specified to provide for excess resin migration, the gap thickness of the wetting-out equipment shall be sized to allow an excess of 5 to 10 percent resin to pass during impregnation. The minimum wall thickness shall be determined at a minimum of three locations on a cut section of the CIPP flat plate sample using a method of measurement accurate to the nearest 0.005 inch. The minimum value shall meet the requirements of Section 2.<strong>07</strong> below. C. CIPP LINER HANDLING Contractor shall exercise adequate care during transportation, handling, and installation to ensure the CIPP material is not torn, cut, or otherwise damaged.

Previous test data will not be acceptable. 1.03 SUBMITTALS The following submittals shall be provided in accordance with Section 2-5.3 of the Standard Specifications: 1. Shop drawings which detail short and long term properties (providing all supporting rest data) of all component materials and construction and recommendations for material storage and temperature control, CIPP liner handling, insertion, curing, trimming and finishing. The submittal shall also include structural calculations for each CIPP liner size, the recommended thicknesses, and the method and equipment used to reinstate connecting sewers. 2. Detailed method for addressing sampling requirements. 3. CCTV Inspection reports as specified in Subsection 3.01. 4. Manufacturer’s recommended installation procedures. 5. Contractor shall submit 10,000-hour third party, 50-year Flexural Creep Modulus test data. Test shall be in accordance with ASTM D-2990 at 10,000 hours or equal test as approved by the Engineer. If approved 10,000 hour tests are not available, Contractor shall use a minimum 50% reduction (50% retention) of Flexural Modulus of Elasticity (per ASTM F-1216 or PSP-15
ASTM F1743 whichever is applicable) for all formula calculations. 6. Manhole connection details. PART 2 <strong>–</strong> PRODUCTS 2.01 GENERAL A. All materials and installation procedures provided by the Contractor for use in the CIPP installation process shall be equal to or exceed the requirements of Sections 5 and 7 of ASTM F1216 or ASTM F2019 Section 5 and 6, as is applicable.

Wrinkles in the finished liner pipe that reduce the structural stability of the pipe are unacceptable. If a void between the wrinkle and the pipe exists, the Contractor shall repair or replace that section of the pipe at no additional cost to the Owner.
