Specifications include, but are not limited to: The improvements consist of furnishing all labor and materials for this project. There is significant corrosion at the waterline with 100% section-loss at several locations throughout the pipes. The existing pipes are structurally deficient and were selected by the Pontis Bridge Management System, for work. This bridge is currently ranked 48th on the 2010 DelDOT Bridge Deficiency List. This project involves the replacement of the existing corrugated metal pipes with a precast concrete three-sided frame. Additional work includes minor raising of the approach roadway, installation of guardrail as needed, and placement of riprap in the stream to prevent scour. The work will be performed under a full road closure with detour, and other incidental construction in accordance with the location, notes and details shown on the plans and as directed by the Engineer.
