USACE--Tulsa District Spillway Dam Virtual Industry Forum

The United States Army Corps of Engineers (USACE) Tulsa District will be hosting a Virtual Industry Forum on 19 April 2024 from 0900 to 1100 to provide information on upcoming spillway bridge replacement projects.  With major spillway bridge replacement projects planned for the future, the District has identified the need to reach out to the construction community and highlight the opportunities available to industry. 

All prospective prime contractors or subcontractors interested to learn more about the Tulsa District’s upcoming spillway bridge construction projects are invited to attend.   

The meeting will be held virtually (MS Teams).  Both contracting and technical representatives will provide information on upcoming projects at Tenkiller Dam (Sequoyah County, OK) and at Fort Gibson Dam (Fort Gibson, OK).

f you would like to attend, please send an email to Jon Larvick (contract specialist) at Jon.A.Larvick@usace.army.mil and provide names, company name, and emails of individuals you'd like invited.  

The Tenkiller Spillway Bridge will be the first project addressed.  Fort Gibson Spillway Bridge could potentially be in the near future.  Each Project’s Magnitude of Price Range is between $25,000,000 and $100,000,000 (DFARS 236.204).  

Tenkiller Lake is a multi-purpose project providing flood risk management, hydroelectric power, water supply, navigation, fish and wildlife, and recreation.

The project is operated for optimum flood risk management in the Illinois River basin as part of the larger Arkansas River Basin. The Tenkiller Lake Main Spillway bridge was originally constructed in conjunction with the dam by Tulsa District in December 1953.

The bridge conveys Oklahoma State Highway 100 over the dam. The bridge consists of ten simply supported spans for a total bridge length of 600 feet. Each span is 52'-0" between bearing centerlines. The superstructure consists of two built-up, welded-steel, plate girders and a framing system of floor beams, stringers, and brackets. This two-girder steel structure lacks load path redundancy and is thus non-redundant and fracture critical. Due to welded construction, major elements lack internal redundancy.

The Tenkiller Spillway Bridge project includes:

•Establishing continuous uninterrupted temporary power to all government facilities (Main Spillway Tainter Gates, Auxiliary Spillway) prior to beginning demolition and construction.

•Demolition of existing Bridge structure and catwalk (Lead abatement needed on catwalk). Mechanical platforms, tainter gates and overall Dam structure will need to be protected during demo and construction.

•Construct new steel catwalk and concrete bridge structure. Ultra High-Performance Concrete (UHPC)to be used on project.

•Roadway improvements to non-overflows of Dam.

The Fort Gibson project will be similar, except that Fort Gibson Spillway Bridge has 30 spans compared to the 10 at the Tenkiller Spillway Bridge.
