Inquiry #1: Please provide the culvert depths to use in the CIPP thickness calculations for culverts at locations 5 & 7-12. CIPP specification section 15-6.11A(3).8 requires the contractor to calculate the required CIPP thickness, and the depth of the culvert is one of the key parameters needed for those calculations. However, there are no profile drawings currently contained in the bid documents for those culvert locations. To ensure all bidders are providing CIPP to the same requirements, depth information that all bidders must comply with should come from Caltrans.
