About this file
This document is a Culvert Inspection Report for a federal infrastructure asset, the Rock Creek Culvert located in Great Smoky Mountains National Park. The report details the inspection findings, recommended maintenance and rehabilitation actions, and associated cost estimates. Key findings include deformation of the culvert barrels, undermining of the north footing, and deterioration of the bituminous coating. Recommended actions include repairing the deformations, constructing headwalls and wingwalls, and repairing the undermined footing. The preliminary cost estimate for rehabilitation is in the range of $XX,XXX, and the priority of improvement is classified as moderate. The report provides details on the structure inventory, load rating, and condition assessments. This information would be used to inform future contracting and maintenance requirements for the federal asset.
