Diagram_RC-52M.pdf

This document is a technical engineering diagram (RC-52M) from the Commonwealth of Pennsylvania Department of Transportation detailing specifications for Type 2 Strong Post Guide Rail installations, specifically for mounting guide rails across culverts and small structures. The multi-page technical drawing set provides comprehensive engineering specifications for steel and timber posts, offset brackets, rail elements, terminal sections, and installation details for roadside guide rail systems. The diagrams include detailed plan and elevation views, specific dimensional measurements, mounting instructions, and notes about material requirements and installation procedures.

The technical specifications cover multiple configurations including different post types (steel, timber), various offset bracket designs, and guide rail mounting options for different terrain and structural conditions. Key technical details include precise measurements for post positioning, bolt specifications, rail element dimensions, and installation guidelines for different span lengths (ranging from 12'-6" to 25'-0"). The document is recommended and dated January 2010, indicating it represents current engineering standards for roadway safety infrastructure. While not a direct bid solicitation, these technical specifications would likely be referenced in transportation infrastructure construction or renovation projects involving roadside safety barriers.
