Request for Information Commercial Clay Source for New Orleans to Venice (NOV), Louisiana (LA) Projects Hurricane and Storm Damage Risk Reduction System
Solicitation # W912EQ26N3401
The U.S. Army Corps of Engineers is conducting market research through a Request for Information (RFI) to identify commercially available clay material sources to support the New Orleans to Venice (NOV), Louisiana Hurricane and Storm Damage Risk Reduction System (HSDRRS). The project requires approximately 5,000,000 cubic yards of clay, with construction contracts anticipated to be awarded between the fourth quarter of Fiscal Year 2027 and the fourth quarter of Fiscal Year 2030. The overall project is scheduled for completion by the end of 2035. This RFI is for information and planning purposes only and does not constitute a formal solicitation or a guarantee of contract award. Interested firms must submit a comprehensive package that includes their business size, socioeconomic status, and a Statement of Capability. Submissions must strictly adhere to the 14 mandatory requirements outlined in Appendix A, which cover regulatory, environmental, and technical specifications. Key requirements include providing a signed Right of Entry, topographic and site layout maps, wetland determinations, coastal zone management permits, and cultural resource reports. Additionally, potential sources must provide geotechnical reports stamped by a licensed professional engineer, confirming that the clay meets specific soil classification standards (CL or CH) and adheres to strict limits regarding organic content, sand content, and salinity. All technical documentation and environmental assessments must be current, typically updated within the last 6 to 12 months. Responses must be submitted via the DoD SAFE portal to the designated point of contact no later than 11:00 A.M. on August 31, 2026.

RFB-758-2700000023-2 | Golf Course Sand
Solicitation # RFB 758 2700000023
The Kentucky Department of Parks is seeking bids for the supply of specialized golf course sand under solicitation RFB-758-2700000023-2, with proposals due by July 29, 2026. The contract requires delivery of multiple quantities of kiln-dried sand types, including Short Mountain 70/30 and Arms Select Topdressing Sand, totaling approximately 590 tons across ten line items. All sand must meet stringent technical specifications, such as a particle size distribution of 4–6% retained on the #18 sieve, a minimum permeability rate of 37 inches per hour, and a penetrometer reading exceeding 2.0 kg/cm², with independent laboratory reports submitted to verify compliance. Bidders may propose equal or equivalent products under Section 8, provided they demonstrate equivalence through descriptive literature and meet or exceed all essential criteria. Deliveries must be completed within 14 days of order receipt under F.O.B. Destination, Freight Prepaid terms, with failure to meet this deadline incurring a 1% daily deduction from the invoice. Evaluation for award will be conducted using a trade-off approach where price is the sole numerically scored factor at 100 points, while delivery capability and sand quality are binary pass/fail thresholds. Offers that fail to meet either delivery or quality requirements will be disqualified regardless of price competitiveness. The solicitation requires strict adherence to Kentucky-specific regulations, including the submission of notarized affidavits for resident or qualified bidder status, potential 15% pricing preferences for eligible entities, and full compliance with state laws regarding AI disclosure, insurance (minimum $1 million liability with AM Best B+ rating), boycott prohibitions, lobbying restrictions, and nondiscrimination obligations under KRS 45.560–45.640. Contractors must also disclose any prior violations of tax, wage, or workplace safety laws and prohibit the use of Commonwealth data to train AI systems. Proposals must be submitted electronically through the Kentucky Vendor Self Service portal by the deadline, with all inquiries due by July 21, 2026. No formal FAR clauses are applied; instead, state procurement language governs contract terms, including provisions prohibiting non-conforming terms, requiring vendor consent for post-award additions, and allowing cancellation with 30 days’ notice. There is no contract value specified, as pricing will be determined by submitted bids, and no electronic invoicing systems like
