Riprap (Stone) Supply – Stone Protection (24”)

The contract entails the supply of 24-inch boulder-sized stone for high-flow erosion protection at various Texas Department of Transportation sites, with all stone required to meet strict size verification standards per ASTM D5519 to ensure effectiveness in high-energy water environments. The material is intended for use in critical infrastructure protection applications where structural integrity and durability under extreme hydraulic conditions are essential, and compliance with the specified testing protocol is non-negotiable for acceptance. The solicitation, classified as a subcontract under NAICS code 327320 for crushed and broken stone manufacturing, is posted with a July 1, 2026, deadline and response date, indicating an immediate procurement timeline with no set-aside provisions. Performance is expected to take place in Washington, Texas, with all deliveries and quality controls tied directly to TxDOT's operational requirements. Documentation and compliance must be fully aligned with TxDOT’s plan repository accessible via their official FTP site, and the absence of a designated point of contact suggests bidders must rely on the published plan library for all technical specifications and submission guidelines.
