S351 and S354 Dam Gate Seal Assembly Sets

This federal government engineering drawing and specification document, issued by the Department of the Army, Jacksonville District, Corps of Engineers, details the fabrication and installation requirements for two vertical lift gates for Structure 354 of the Central and Southern Florida Flood Control Project. The document outlines technical specifications, materials, and installation guidelines for the gates under Bid Item No. 10. Key requirements include utilizing A-36 structural steel for primary materials, Type 304 stainless steel for corrosion-resistant components, and SAE 1045 or better steel for shafts. Detailed mechanical guidelines are provided for the assembly of rubber seals, 14-inch and 7-inch outer diameter rollers, grease lines, 3/8-inch skin plates, and weep holes. Contractors are permitted certain structural options, such as substituting anchor bars with specific anchor studs and utilizing cast steel instead of ductile iron, subject to engineering approval. The document establishes strict standards for welding, galvanization after fabrication, and precise field vulcanization of rubber seal corners to ensure structural integrity and operational compliance for flood control operations.

This combined synopsis/solicitation (Solicitation Number: W19EP26QA015) is issued by the U.S. Army Corps of Engineers (USACE), Jacksonville District, as a Request for Quotation (RFQ) to procure five commercial dam gate seal assembly sets. The requirement is not set aside for small businesses and consists of three S351 seal sets and two S354 seal sets, which must be shipped in protective wooden crates to Clewiston, Florida. The dam gate seals require specialized manufacturing using a specified compound. Technical specifications dictate material characteristics, including a durometer rating of 60-70, tensile strength of 3000 PSI, minimum elongation of 450%, and low-temperature brittleness protection. The S351 seals feature a rectangular J-bulb configuration with PTFE cladding and molded corners. The S354 seals have a larger rectangular layout with similar J-bulb and flat seal profiles. A critical fabrication constraint requires all seals to be supplied without bolt holes. The acquisition will be awarded under the Lowest Price Technically Acceptable (LPTA) evaluation process. Timely quotes will first be assessed on a pass/fail basis for technical acceptability, and award will be made to the lowest-priced, technically compliant offer. Questions regarding the RFQ are due by July 24, 2026, and final quote submissions are due by July 31, 2026. The solicitation incorporates standard FAR and DFARS commercial item clauses, including Buy American provisions and Item Unique Identification (IUID) marking requirements for applicable items.

This US Army Corps of Engineers (USACE) memorandum is a formal procurement request for five specialized Dam Gate Seal Assembly Sets: three for the S351 dam and two for the S354 dam. The seals must be fabricated using high-performance USBR neoprene rubber meeting strict material standards, including a 60-70 durometer rating, 3000 PSI tensile strength, and low-temperature brittleness resistance. Both configurations require rectangular gate seal assemblies featuring molded J-bulb top and side seals with PTFE cladding, molded flat bottom seals, and hot factory-vulcanized spliced corners. A critical fabrication constraint requires all seals to be supplied without bolt holes. To prevent damage during transit, the finished assemblies must be securely packaged in protective wooden crates. USACE will provide detailed reference drawings to the selected vendor to ensure precise manufacturing and splicing. All completed shipments are to be delivered to Clewiston, Florida. Technical inquiries and reference print requests should be directed to Donald R. Swingle at USACE.

This technical specification document outlines the procurement and fabrication requirements for rubber gate seals (S-354). It details the precise dimensions and material profiles needed for three types of rubber seals—side, top, and bottom—designed for a gate assembly. The top and side seals feature a "P-shaped" profile (5 inches wide by 1 ¾ inches high) with specific bulb and flat section measurements, and they require Teflon cladding. Additionally, the corners connecting the side seals to the top seal must be meticulously fitted, spliced, and vulcanized by the manufacturer prior to shipping. The bottom seal is a solid rectangular rubber block measuring 4 inches wide by 1 inch thick. While the individual specifications and quantities are detailed for a single gate, the document explicitly instructs bidders to quote enough materials and fabrication services for two complete gates. This procurement is typical of state, local, or federal water control and infrastructure maintenance projects.

This federal procurement document outlines the technical specifications for replacing the seal systems on three water control gates at Structure S-351. Each gate requires two distinct seal profiles fabricated from 60 Durometer Neoprene: a J-type profile for the top and sides, and a solid rectangular block profile for the bottom. For each of the three gates, the contractor must supply two 8-foot side seals and one 20-foot 9 3/4-inch top seal, all featuring Teflon cladding. Crucially, the corners where the side and top seals meet must be molded and hot-vulcanization spliced during manufacturing prior to shipment. Additionally, each gate requires one solid rectangular bottom seal measuring 20 feet 9 3/4 inches in length, 4 inches in width, and 1 inch in thickness. All materials must conform to the attached engineering prints for Structure S-351.
