The Tabulation of Drainage Quantities in the plan sheets does not specify an allowable pipe material. FP‐03 602.03 specifies to furnish the same material as existing for culvert extensions. The plans show several instances where the pipe to be installed is tying into existing stub‐outs. Does section

602.03 apply for this work? If so, please clarify the allowable pipe material and the existing pipe material.

Any compatible and appropriate pipe material having the maximum specified Manning’s Roughness coefficient should be acceptable. Most of the previously installed pipe was PVC and ADS. A new pipe material should be compatible with these types.
