THIS IS A SOURCES SOUGHT NOTICE ONLY FOR RELIEF WELL PUMPING AT THE CHENA RIVER LAKES FLOOD CONTROL PROJECT, NORTH POLE, ALASKA. OFFERS OR PROPOSALS WILL NOT BE ACCEPTED FOR THIS NOTICE. THIS IS NOT A PRE-SOLICITATION. The Alaska District of the U.S. Army Corps of Engineers is conducting market research to facilitate a determination of acquisition strategy prior to releasing a solicitation for this anticipated project. The determination of acquisition strategy lies solely with the government and will be based on market research and information available to the government from other sources. Please note that this Sources Sought is for information only and does not constitute a solicitation for competitive offers/proposals and is not to be construed as a commitment by the Government. However, all interested parties who believe they can meet the requirement are invited to submit information describing their capability to provide the required services. DESCRIPTION OF WORK: Provide all management, labor, equipment, travel, supplies, materials to perform relief well pumping on as many as 174 relief wells at the Chena River Lakes Flood Control Project located approximately 18 miles east of Fairbanks, Alaska near the town of North Pole. Conditioning and Pumping Tests All pumping tests must conform to Engineer Manual 1110-2-1914, Design, Construction, and Maintenance of Relief Wells and ASTM D 4043-17, Standard Guide for Selection of Aquifer Test Method in Determining Hydraulic Properties by Well Techniques. Work to be performed on all relief wells are as follows: • Brushing screen • Air surging • Remove all sediment from inside well (organics, fines, sand, and/or gravel) • Perform Step-drawdown test to determine the well’s efficiency(s) and establish the effective (optimum) pumping rate, the theoretical Specific Capacity for the (optimum) pumping rate, and determine the hydraulic conductivity Brushing Brushing of the interior of the well, from the riser thru the screened section is often employed as a ‘pre’ treatment to mechanical rehabilitation. The required brushing consists of attaching an appropriately designed stiff poly or nylon brush to drill pipe or an approved apparatus and brushing the interior of the well. It is required that brushing be accomplished in small sections, to ensure thorough cleaning of the interior of the well. Air Surging Air surging consists of alternating cycles of air surging and airlift pumping using suitably sized airline and air compressor. Prior to the start of the surging action, well flow should be initiated by injecting compressed air, above the screen, at a reduced rate, until uninhibited flow through the well screen is achieved. This will reduce the potential for screen collapse during initial surging. Once uninhibited flow through the well screen is achieved, the surging action can be initiated by cycling between air surging and airlift pumping. The cyclic surging must be performed at five-foot intervals throughout the length of the screen, for a period of 5 minutes, per interval. One full pass of air surging along the entire length of each well screen is required to penetrate maximum energy into the filter pack. Remove Sediment Sediment may exist or may be generated during well conditioning. The sediment may consist of organics, fines, sand, and/or gravel. All sediment must be removed from all intact serviceable relief wells before the step-drawdown tests. An air lift system is recommended for this process. Perform Step-drawdown The aquifer's response or drawdown is measured to determine well efficiency and the effective pumping rate for a constant-rate pumping test. A well is pumped at a constant rate for a given period of time. The pumping rate is successively increased or stepped for each of several time intervals. The water level is measured during each step (interval), and drawdown is calculated for each pumping rate. Perform a Step-drawdown Pumping Test using the Cooper-Jacob method to determine the (optimum) pumping rate. Determine a minimum of four pumping rates to perform the test. From the results of this test, determine the theoretical Specific Capacity for the (optimum) pumping rate, and determine the hydraulic conductivity. Information from previous pumping tests indicate steady-state flow will occur at the front end of the Theis Curve; therefore, the Cooper-Jacobs method is prudent for this unconfined aquafer. Prepare a detailed Relief Well Maintenance Pumping Report The final report shall include a timeline summary of work performed, a list of all equipment used and their conditions, a schematic and/or illustration of all operating apparatuses used, all field notes, pumping test reports, sand infiltration test sheets, and a list of all personnel, their qualifications, positions, and work performed. The units for all analytical information provided to the owner must be in the U.S. customary system. The Final report must be stamped by an Alaska licensed professional engineer. The estimated award date of this contract is April 2022. This procurement is subject to the availability of funds. If the project is cancelled, all proposal preparation costs will be borne by the offeror. All offerors are advised that they must be registered in the System for Award Management (SAM) (www.sam.gov) before submitting a proposal. Joint ventures must also be registered in SAM as a joint venture. Offerors are advised to begin this process when they prepare their proposal in order to ensure registration is in place should they be selected for award. Lack of registration in the SAM database would make an offeror ineligible for award. The intent of this Sources Sought is to solicit interest from qualified firms with a primary North American Industrial Classification System (NAICS) code of 541380 Testing Laboratories, which has a small business size standard of $16.5 million. In accordance with FAR 19.501 paragraph (c) The contracting officer shall conduct market research and review the acquisition to determine if this acquisition will be set aside for small business or considered for an award to a small business under the 8(a) Program (see FAR subpart 19.8), HUBZone (see FAR subpart 19.13), service-disabled veteran-owned (see FAR subpart 19.14), or women-owned small business program (see FAR subpart 19.15). If the acquisition is set aside for small business based on this review, it is a unilateral set-aside by the contracting officer. THIS IS A SOURCES SOUGHT OPEN TO ALL QUALIFIED PRIME CONTRACTOR FIRMS (Large and Small Businesses under NAICS 541990). All interested firms are encouraged to respond to this announcement no later than 7 December 2021, by 10:00 AM Alaska Standard Time, by submitting all requested documentation listed below to: US Army Corps of Engineers, Alaska District, ATTN: CEPOA-CT (Gosh), PO Box 6898, JBER, AK 99506-0898 or via email to Jennifer.Gosh@usace.army.mil and Christine.A.Dale@usace.army.mil. Interested prime contractor firms are encouraged to submit a capabilities package (not exceeding 5 pages) demonstrating the ability to perform the work described above. Packages should include the following information regarding their company: 1. Company Name, Address, DUNS Number, Cage Code, Business Size under the applicable NAICS above, and Point of Contact information including email and phone number. 2. SAM status, Large or Small Business status under the applicable NAICS above, and type of small business (8a, HUBZone, Service-Disabled Veteran-Owned, Women-Owned, etc.) 3. Demonstration of the firm’s experience as a prime contractor on projects of similar size, type, and complexity within the past ten years. List actual projects completed and include project title, location, and a brief description of the project. 4. Your company’s intent to propose on the Relief Well Pumping at the Chena River Lakes Flood Control Project project as a prime contractor. Interested parties are invited to submit a response to this Sources Sought by the response time stated above. Please submit all documentation by email in PDF format. Responses received after this time and date may not be reviewed. Revised 9 November 2021 to updated NAICS Code from: 541990 - All Other Professional, Scientific, and Technical Services to 541380- Testing Laboratories.
