RE: Design Thickness Calculation Statement: ODOT 313-26 Culvert Maintenance

To Whom it may Concern, Inliner Solutions is issuing this statement in lieu of providing all thickness calculations based upon the pipe size, ovality, and height of cover scenarios.

Inliner Solutions used the same methodology on this submitted calculation as we did on all thickness calculations submitted with our bid.

The input thicknesses identified in our pricing are direct outputs from MOP-145 designs. In many cases, installed liner thicknesses will exceed MOP-145 thresholds due to manufactured CIPP minimums.

Example: 12” minimum thickness equals .24in minimum.

Transparency per installation to be provided based on actual scope encountered.

Item of note: The disclaimer on the submitted stamped sample design, is a function of ClinT Software (program to perform the MOP-145 designs required) and is not a statement by Inliner.

Please contact me at 614.374.0874 (mobile) or 614.529.6440 (office) should you require additional information or have questions.

Sincerely, Inliner Solutions, LLC
