About this file

Written by GovTribe AI · Dec 27, 2023

This federal solicitation seeks construction services to rehabilitate critical structures along the Missouri River Bank Stabilization and Navigation Project between Sioux City, Iowa and Rulo, Nebraska. The work includes adding quarried rock to repair areas of deterioration on revetments, dikes, kickers, L-head dikes, and vanes across approximately 230 river miles. In areas with substantial structural material loss, the contractor will effectively rebuild parts of the damaged infrastructure. The solicitation was issued by the Department of the Army Corps of Engineers Omaha District to strengthen flood protection and maintain the navigation channel following damage from 2019 flooding events.

IT IS PREFERABLE THAT THE REPAIR SEGMENT TERMINATES IN AN AREA WITH GOOD QUALITY BANK MATERIAL BACKING FINAL REVETMENT GRADE IN THE REPAIR SECTION MAY BE HIGHER THAN AN ADJACENT UNREPAIRED SECTION.

2. REVETMENT STRUCTURE REPAIRS MAY INCLUDE ONE OR MORE SEPARATE SEGMENTS AND NOT THE ENTIRE STRUCTURE.

THE LANDWARD DIKE END BE AT A LOWER ELEVATION THAN THE RIVERWARD END.
