About this file
This document package contains plans and specifications for a federal construction contract opportunity with the U.S. Army Corps of Engineers to perform erosion repairs on levees along the Mississippi River in Sabula, Iowa. The work includes repairing sections of the north and south river levees through stripping vegetation, hauling and placing impervious and pervious borrow materials, conducting surveys, and seeding the north levee once complete. Amendment 0001 revises the schedule of prices, updates specification sections, and adjusts the estimated price range for the work from between $100,000 to $250,000 to between $250,000 to $500,000. Plans show repair areas and sections, borrow sites for material, clearing limits, and other construction details. The opportunity remains open until award.
