2022 Missouri Standard Plans for Type A Concrete Barrier.pdf

This is a technical standards document for Type A Concrete Barriers issued by the Missouri Department of Transportation. The document provides standardized specifications and design plans for the construction and installation of 10-foot Type A concrete highway barriers used in transportation infrastructure projects throughout Missouri. The specifications include detailed technical requirements, dimensions, reinforcement details, and construction standards that vendors and contractors must adhere to when supplying or manufacturing these barriers. The document serves as the reference standard for the Missouri Department of Transportation Kansas City District's procurement of 100 units of 10-foot Type A concrete highway barriers as a one-time purchase awarded on a lowest and best bid basis.

The technical standards document establishes uniform construction specifications to ensure quality, safety, and consistency across all Type A concrete barrier installations within Missouri's transportation network. These specifications are mandatory for all bidders responding to the procurement opportunity and ensure that all supplied barriers meet the established performance and durability requirements. The standardized plans reduce variability in products received and facilitate proper installation and maintenance procedures across the state's infrastructure projects.
