- Description
- This is a Request for Information (RFI). Responses to this Sources Sought Market Research Announcement will be used by the Government to make an appropriate acquisition decision regarding the use of a brand named product. The purpose of this RFI is to identify construction material/component(s) that are equal to the salient characteristics noted below. The construction material/component is proposed for use on the Intake Dam Modification Project, which is currently in the design phase. The Intake Dam Modification Project is a joint project under development through a partnership between the U.S. Bureau of Reclamation and U.S. Army Corps of Engineers. The construction project will consist of two primary project components,a fish screen to prevent pallid sturgeon and native fish from entering the canal during diversion operations,and a fish passage to allow upstream and downstream movement of migrating fish around or over the existing diversion dam. Preliminary investigations into the fish screen component have been conducted by the interagency team over the past several years. The team has proposed utilization of stainless steel screens with integrated passive (self-cleaning) or active cleaning systems (mechanical, water jet, or air burst) to remove debris and biological growth which would interfere with flow and screen operations, a patented technology from Intake Screens Inc. Since the primary fish species of concern for this project is the endangered pallid sturgeon, and no existing screening criteria have been developed for that species, it has been recommended that the screen be designed to meet U.S. Fish and Wildlife Service and National Marine Fisheries Service requirements as specified for salmonid and other anadromous and native fish species on the west coast. NMFS criteria are specified in technical memos Juvenile Fish Screen Criteria revised February 16, 1995 and Anadromous Salmonid Passage Facility Design, dated February 2008 which include the following guidelines: a. Where practical and biologically desirable, the screen shall be constructed at the diversion entrance with the screen face generally parallel to the river flow; b. The approach velocity shall not exceed 0.40 fps (0.12 mps) for active screens or 0.20 fps (0.06 mps) for passive screens; c. The sweeping velocity shall be greater than the approach velocity (preferably at least two times the approach velocity but no more than 3 fps); d. The screen material shall be corrosion resistant and sufficiently durable to maintain a smooth uniform surface with long-term use; e. The screen openings shall not exceed the following dimensions: 0.0938 in (2.38 mm) for perforated plate screens; 0.0689 in (1.75 mm) for profile bar screens (narrow dimension); 0.0938 in (2.38 mm) for woven wire screens (diagonal dimension). f. All manifold connections and seals connecting moving parts of the screen shall be no larger than the largest screen opening specified above; g. The screen shall provide a minimum of 27% open area; h. The screens shall be automatically cleaned as frequently as necessary to prevent accumulation of debris (proven cleaning technologies are preferred); i. The maximum head differential to trigger screen cleaning for intermittent type cleaning systems shall be 0.1 ft (0.03m): In addition to meeting NMFS and USFWS criteria for screen performance, it is highly desirable to have the screen account for other design requirements. a. The screen shall accommodate operation under variable river water level conditions: Yellowstone River water surface elevations fluctuate approximately 10 feet at the project site during the operation season; River depth at low flow is approximately 10 feet (8 feet under extreme low flow conditions); Base elevation of the screen shall be within 1-2 feet of the river thalweg. b. The screen shall accommodate annual installation at prior to the start of the irrigation season (typ. mid to late April) and removal prior to the start of winter to protect the screens from ice loadings which occur almost annually at the project site; c. Tracks or channels on which the screens are raised and lowered shall be reinforced or otherwise protected from ice loading; d. Use of multiple individual screen units which can be removed for maintenance while continuing operation of the other screens is preferable; e. Individual screen units shall be designed and/or reinforced to withstand high debris loads without damage while maintaining continued water delivery; f. Screen units shall incorporate cleaning mechanisms on both leading and trailing sides of the screen to remove debris and biological growth from the screen surfaces; g. Utilization of proven screens and technologies is preferred; h. Minimization of power demand is preferred due to limited power supply capacity at the existing project site; i. Screen units shall be durable and reliable to reduce operation and maintenance costs to the maximum extent possible. Firms are invited to provide information, specifications, brochures, manuals, availability of products equal to the salient characteristics and application noted in this announcement, to include: demonstrated capabilities, product past performance and application, place of Manufacture; part number, drawing number, etc; size, dimensions, or other form, fit or functional description; indicate foreign or domestic manufacturer,if foreign specify country of origin; information pertaining to experience on previous projects, specific work previously performed or being performed, any in-house research and development effort, and any other specific and pertinent information that would enhance our consideration and evaluation of the information submitted. Respondents are encouraged to submit information by mail to the address specified or via email (5MB limit) to Wanda Carter-Davis at wanda.c.carter-davis @usace.army.mil with the Subject Line Intake Screens no later than 3p.m.(CT) on August 24, 2009. Information provided will not be returned. Responses and comments will be shared with the Government project team, but otherwise will be held in strict confidence. Vendors must appropriately mark each page of their submission that contains proprietary information. Omaha District will adhere to Federal Acquisition Regulation policy on handling proprietary information. This is not a Request for Proposal and no contract will be awarded as a result of this RFI. The Government reserves the right to post additional notices relative to the RFI and request additiohnal capability statements and/or similar documentation. Please note that no registration is required nor is a bid list maintained.
