Repair of Dam Spillway Gates at Lake Hartwell, GA.

This is a Sources Sought/Request for Information only. This is not a Solicitation Announcement, nor is it a Request for Proposal does not obligate the government in any contract award. The U.S. Army Corps of Engineers, Savannah District, is conducting preliminary research to determine the market capabilities of potential contractors to perform corrosion preventive maintenance of 12 tainter (spillway) gates, associated stop logs, hoisting machinery, and replacement of deteriorated J-seals and bolts (3 J-seals and approximately 300 bolts per gate). Technical Details: COATING REQUIREMENTS. The contractor shall clean all surfaces in accordance with SSPC-SP 5- WHITE METAL TO MEET PAINT MANUFACTURER REQUIREMENTS. ABRASIVE blasting is the preferred method of preparation, but alternative paint removal systems will be considered, and evaluated based on their ability to provide a surface condition which meets the paint manufacturer’s specifications, meet environmental requirements and perform

satisfactorily in the opinion of the Government. Combinations of systems such as water blast for cleanliness/paint removal and grit blasting for surface profile would also be considered. Blast medium shall have a low chloride concentration and be so noted on the packaging. Immediately prior to application of the coating, the surface shall be randomly examined for soluble salts in accordance with the Bressler Sampling Method. No area shall exceed a value of 12 micro siemens. The Contractor shall apply VINYL 5-EZ paint System, see UFGS 09 97 02 - Paint Hydraulic Structures, to all parts of the upstream side of the gate. Paint shall be applied to an average dry film thickness of a minimum of 7.0 mils for the completed system, and the thickness at any point shall not be less than 5.5 mils. Specific Paints: Surface Preparation Approaching white metal 1st Coat White Vinyl V766e (double spray coat) 2nd Coat Gray Vinyl V766e (double spray coat) 3rd Coat White Vinyl V766e (double spray coat) 4th Coat Gray Vinyl V766e (double spray coat) Background Corrosion can occur at any location on a gate; however, certain areas are more susceptible than others. Sensitivity to corrosion is enhanced at crevices, locations of dissimilar metals, areas subject to erosion, and areas where ponding water or debris may accumulate. Other areas that are susceptible to corrosion include where it is difficult to adequately apply a protective coating, such as at sharp corners, edges, intermittent welds, and locations of bolts. Corrosion-susceptible locations on tainter gates include trunnions with dissimilar metals, seal connection plates and rib-girder connections (crevice corrosion and dissimilar metals), locations of bolts (crevice corrosion), drain holes, and general areas where sharp corners, edges, and intermittent welds are located. Other areas where corrosion is likely to occur is where heaters are located and at the normal water line. All interested firms with 237990 as an approved NAICS code shall submit the following information: 1.Name and Address of your Firm 2.Point of Contact (name/phone/email) 3.Company website 4.Commercial and Government Entity (CAGE) code (http://www.dlis.dla.mil/cage_welcome.asp) 5.Business Size, according to the specified NAICS code 237990, to include designation as HUBZone, 8(a), Service-Disabled Veteran Owned Small Business, Small Disadvantaged Business, Woman­Owned Business, and Large Business.
