McNary Downstream Miter Gate Replacement

The McNary Downstream Miter Gate Replacement is a federal infrastructure project at a U.S. Army Corps of Engineers lock and dam facility on the Columbia River. The scope centers on heavy-lift gate replacement at a critical navigation chokepoint, which requires extended waterside staging, barging equipment, and restricted-access work zones during active river operations. Mobile surveillance towers fit the staging-yard and equipment-laydown monitoring requirement, and camera arrays cover the approach corridors and crane-boom swing radius where visual oversight prevents collision and theft during nights and weekends. The opportunity posted May 1 as a Sources Sought notice on SAM.gov, the earliest pre-solicitation stage. This is a pre-budget signal, the ideal entry point. The Corps typically runs a 30-60 day sources-sought window, then moves to full solicitation with security and site-access requirements baked into the bid package. Engaging now, before the security line item is drafted, positions Zedcor to shape the spec rather than respond to it. Project value is undisclosed in the source record. Seattle branch is the nearest at 210 miles, inside the 300-mile coverage radius. No warm customer path exists in the region. The immediate next step is identifying the Corps project manager listed on the SAM.gov posting (typically a civil works PM or contracting officer's representative) and proposing a pre-solicitation conversation about staging-area security and waterside equipment monitoring. Lead with mobile-tower availability for the barge-staging phase and ask about the anticipated solicitation timeline.

  Saw the McNary miter gate sources-sought posting from May 1. Seattle covers the corridor at 210 miles out, worth a call on staging-yard tower coverage before the solicitation drafts the security spec?
