About this opportunity
The U.S. Army Corps of Engineers Engineering District St. Paul is seeking to procure specialized dredge hoses for the Dredge Goetz through this solicitation. The procurement includes two distinct hose types: two (2) Dredge Goetz Discharge Hoses and ten (10) Limber Line Discharge Hoses, both with specific technical requirements. Each hose must be 20 inches in internal diameter, capable of withstanding 200 PSI operating pressure, and constructed with wire-reinforced black rubber tubing and steel-reinforced vulcanized flanges. The hoses are intended to support dredging operations involving fine to medium coarse sand, with detailed specifications including flexure capabilities, tensile load requirements, and specific flange configurations. Quotes are due by March 28, 2025, at 5:00 PM, and must be submitted electronically to the contracting officer, with manufacturers required to provide comprehensive technical documentation and standard commercial warranty details.
This solicitation is set aside for total small business participation, specifically within the NAICS category 326220 for Rubber and Plastics Hoses and Belting Manufacturing. The hoses will be delivered to the Army Corps of Engineers Civil Works Service Base located in Fountain City, Wisconsin, with a delivery deadline of August 29, 2025. The procurement is structured as a firm fixed-price contract, with vendors expected to provide hoses that can accommodate 40 degrees of swing in both starboard and port directions while maintaining operational integrity. Each hose must include protective packaging to prevent transportation and UV damage, and the warranty must be honerable at any authorized service center within the current operating area of the Dredge Goetz fleet. While specific award value is not explicitly stated, the technical complexity and specialized nature of the hoses suggest a potentially significant contract value for the selected vendor.

SUBJECT: Scope of Work/Technical Specifications
Dredge Goetz Discharge Hose (Quantity 2)
1. General Information.
- Intended use. The hose, described herein will be used to conduct dredge slurry from the rigidly fixed dredge discharge pipe of the U.S. Army Corps of Engineers Dredge Goetz to the rigidly fixed pipe of a pontoon string. The hose is intended to provide all the flexure necessary to connect a swinging hydraulic cutter dredge to a fixed discharge line supported on pontoons. The dredge discharge pipe has an internal diameter of 20 inches.
- Slurry. The hose will carry a water and sand slurry consisting of 0 to 40% medium grain size sand.
- Line pressure. The hose shall be capable of safely withstanding an operating pressure of 200 psi. The safety factor used by the manufacturer in the design of the hose to ensure safe operation at 200 psi shall be specified by the offeror in their quote. The hose will not be subject to a vacuum.
- Diameter. The hose inside diameter shall be 20 inches. The diameter shall be measured at the inside of the lining.
- Length. The length of the hose shall be 24 feet when measured from inlet flange to outlet flange.
- Flexure. The hose shall be capable of flexing to accommodate 40 degrees of swing to the starboard of centerline and 40 degrees to the port of centerline by the dredge while the pontoon remains stationary.
- Hose flanges. The manufacturer shall supply permanently affixed steel inlet and outlet flanges suitable for the use intended. The flanges shall be vulcanized to the hose. The recommended method of securing the hose flange to the mating flange shall be explained in the manufacturer’s quote. The flanges shall be rubber lined. The rubber shall extend from the inner tube through the flange and up the flange face.
- Hose tensile load. Hose tensile load caused by the drag of the pontoon string will be less than 10,000 pounds. Most of the tensile load will be carried by a pivoting hitch that connects the pontoons to the dredge.
- Packaging and Shipping. The hoses shall be packed in a manner suitable to provide protection from damage during transport and UV rays during storage.
- Warranty. The offer’s quote shall specify the terms of the standard commercial warranty supplied with the proposed hose. The warranty will be honored at any authorized service center in the country or current location of the Goetz dredge fleet.
