The Contractor shall be responsible for all costs associated with the chemical<br />
resistance tests.<br />
Proof of meeting these requirements shall be provided to the engineer for<br />
approval at least seven (7) days prior to commencement of work.<br />
2.04 COMPONENT PROPERTIES<br />
A. FIBERGLASS TUBING<br />
The fiberglass tubing shall be made of non-corrosion material in Advantex<br />
(ECR) quality and shall be free from tears, holes, cuts, foreign materials and<br />
other surface defects.<br />
B. RESINS<br />
The physical properties quoted in Section 2.06 apply to CIPP manufactured<br />
polyester or vinylester resin. Resins should be appropriate for conditions<br />
encountered.<br />
2.05 FINISHED AND CURED CIPP LINER PROPERTIES<br />
A. The physical properties of the cured CIPP shall have minimum initial test<br />
values as given in Table 1 for polyester and vinylester resins. Properties for<br />
these or any other enhanced resins shall be substantiated with test data.<br />

2.06 DIMENSIONS<br />
A. Contractor shall make allowances in determining the inliner tube length and<br />
circumference for stretch during installation and shrinkage during curing. The<br />
minimum length shall be that which continuously spans the distance from the<br />
center of the inlet manhole to the center of the outlet manhole. The Contractor<br />
shall verify the lengths in the field before the inliner tube is cut and<br />
impregnated. Individual installation runs may include one or more manhole-tomanhole<br />
sections as approved by the Engineer. Installation of the liner shall be<br />
through existing or new manholes. Excavation for liner insertion shall not be<br />
permitted except to replace the manhole cones, if necessary and/or required.<br />
B. The diameter of the existing pipes may be larger than the nominal inside<br />
diameter. It is the Contractor’s responsibility to determine the required<br />
diameter of the liner.<br />
C. The maximum wall thickness shall be at least the calculated design thickness,<br />
or the minimum specified, to increase the diameter only as much as necessary.<br />
2.<strong>07</strong> DESIGN CRITERIA<br />
A. The liner shall be designed for a “fully deteriorated” pipe condition in<br />
accordance with the procedures of ASTM F1216, Appendix XI and these<br />
