This is a 100% Total Small Business Set-Aside under NAICS 212319 for providing durable stone. The work involves loading material onto government-owned barges at a location on the Missouri River near river mile 52.8. A government-furnished loading dock barge will be available, but the contractor must provide suitable land for the loading facility if they do not already have one established on the river. The stone must meet specific durability requirements, including a bulk specific gravity of not less than 2.40 and soundness standards for freeze-thaw cycles. No gradation test prior to shipping or credentialed CQM staff are required.
