About this opportunity
This pre-solicitation notice is seeking contractors to modify the rocker bearings at Pier 10 of the Oahe Project bridge. The U.S. Army Corps of Engineers Engineering District Omaha requires contractors capable of repairing portions of the bridge located above the waterline using heavy machinery. Contractors must have the ability to place elevated concrete using pumping systems or chutes, install scaffolding above water for work, install adhesive anchors with qualified inspectors, and mechanically scarify and core drill through four feet of existing concrete. Pressure grouting equipment and methods to scan for existing reinforcement are also needed. The solicitation for this total small business set-aside will be posted on August 18th, 2022 with proposals due by September 20th, 2022.
This project is a 100% total small business set-aside, with the primary NAICS code 237990 (Other Heavy and Civil Engineering Construction) and PSC code R499 (Construction of Structures and Facilities).

The following conditions must be met to successfully complete the task: A system for placing elevated concrete, such as a pumping system or chutes that descend from the bridge's surface. Scaffolding is placed above the water so workers can do the job (bar placement, formwork placement, tensioning and a bar-tensioning jack. An installation team for the adhesive anchors, as well as qualified test inspectors.
