MRG RIPRAP STOCKPILE

The Bureau of Reclamation’s Upper Colorado Regional Office is seeking information from qualified small businesses to assess their ability to supply, haul, and stockpile riprap for river-maintenance and emergency protection efforts along the Middle Rio Grande in New Mexico. This sources-sought notice, issued under solicitation number 140R4026Q0098 and classified as a total small business set-aside under FAR 19.5, is not a solicitation for proposals but a market research tool to identify capable contractors. The requirement calls for the delivery of 9,680 tons of riprap across three designated sites: 3,300 tons of 12-inch nominal diameter material at Bernalillo, 5,500 tons of 16–24 inch riprap at HWY 380, and 880 tons of 16–24 inch riprap at RM 201.8, with the latter contingent upon approval from Sandia Pueblo. If approval is denied, the material must be redirected to Bernalillo. All work must be completed by July 1, 2027, with mobilization beginning no later than 15 calendar days after the Notice to Proceed. Responses are due by July 8, 2026, at 10:00 AM PST and must be emailed to Savanna Manning at savanna_manning@ios.doi.gov, including the respondent’s SAM.gov Unique Entity Identifier, business size status, capability statement, and details of three similar past projects—all submitted as unclassified Word or PDF files. Contractors must comply with strict material specifications, including a minimum specific gravity of 2.65, absorption not exceeding 2%, sulfate soundness loss under 10%, and angular, clean, uncontaminated rock conforming to ASTM standards. Delivery and stockpiling require dust abatement measures, and all riprap must be weighed by certified public weighmasters with detailed tickets submitted monthly. Safety is paramount: contractors must submit a safety program and traffic control plan 15 days prior to mobilization, designate an onsite safety representative physically present during all operations, and submit monthly accident reports. Material testing results, source locations, and weighmaster certifications must be provided ahead of delivery. Work hours are restricted to Monday through Friday, 6:00 a.m. to 6:00 p.m., and the contractor must secure all access, THPO
