Questions & Answers / Clarifications

This document provides answers to vendor questions regarding the Dobson Site Rock buy and delivery opportunity.

• Delivery Timeline: Delivery can begin the same day as award or soon after. Bidders should contact the POC to coordinate specific times and dates.
• Aggregate Delivery: All Type 1 rock and other aggregates cannot be delivered on the same day due to potential volume limitations at the delivery point. This is noted as a potential issue requiring coordination.
• Product Approval: Products for access and county roads do not need to be KDOT approved, as the project is located in Missouri, not Kansas.
• Type 1 Rock Gradation: The document provides gradation specifications for Type 1 Rock Structure and Type 1 Rock – 5 Hardpoints, noting that both refer to the same rock type used for different purposes. A table details the percent passing for various sieve sizes and approximate spherical diameters.
• 6-inch Minus and 1-inch Clean Gradation: There are no specific gradation requirements for the 6-inch minus and 1-inch clean aggregate products.

An amendment to the solicitation will be forthcoming, likely addressing the delivery coordination mentioned in Question 2.
