BACKGROUND AND PURPOSE:

For the purpose of market research, The U.S. Army Corps of Engineers, Vicksburg District requests letters of interest from qualified construction contractors capable of performing construction services for the following project:

Pike County, Arkansas, Narrows Dam, Intake Structure Replacement Project, Little Missouri River, Lake Greeson.

PROJECT DESCRIPTION:

Intake Structure Replacement Project

The Narrows Dam Intake Structure is planned to be replaced due to deterioration of the steel intake structure that supports the trash racks in front of the hydropower generating units. The work will only include the intake structure between Unit 1 & 2 which will be denoted on the drawing attached. The structure is made up of steel beams and columns that were originally embedded into the concrete. The replacement structure will utilize post-installed concrete anchors in place of cast-in anchors. The elevation of the bottom of the structure is at EL. 478.0, and the top of the structure is at EL. 551.0. Underwater grouting may be required to ensure that the new structure is plumb. The concrete platform that the structure supports may be removed during construction. If removed, it shall be replaced with a precast concrete deck or a fiber reinforced polymer deck. Underwater welding may be required to install the structure and should follow AWS D3.6M:2017. Any welding not performed underwater will follow AWS D1.1:2020. The replacement structure must be coated prior to installation and may require touch-up coating underwater after installation. As an additional protection measure, a cathodic protection system should be included in the design and attached to the structure.

Work on the intake structure will require a planned lake pool deviation. The deviation is planned for a minimum of 120 days. The minimum lake pool elevation is EL. 534.0, and dive depths may reach up to 70 feet. Due to the size of the lake and the drainage area, lake levels may rise rapidly during construction. This may require discharge of water through the flood control gates, and in the case of an extreme event water may overtop the emergency spillway which has a crest at EL 563.0.

Access to the top of the dam is limited, and the size of the crane that may be placed on the dam is restricted to a 90-ton crane. This crane can only be placed in designated areas as outlined in Figure 1 below. Barges may be hauled in and launched upstream of the dam to provide a larger work platform.

The contractor must have at least 5 years of experience and have successfully completed a minimum of three (3) similar projects as outlined herein. Highlight any experience that would include underwater construction, installation of post-installed mechanical anchors, and steel structures.
