About this file
This document contains two National Park Service standard drawings for G4 W-beam guardrail installation and repair. Drawing 617-11 specifies the layout and components for standard guardrail installation with steel posts, including post spacing and dimensions, rail and block details, delineator placement, and notation regarding special contract requirements. Drawing 617-13 provides specifications for guardrail installation in rock conditions, outlining two cases for drilling post holes based on the depth of overlying material and providing plans for hole configuration and aggregate backfill.
The related federal contract opportunity is a solicitation from the National Park Service Intermountain Region to perform guardrail repairs at Yellowstone National Park. The solicitation number is 140P1323R0004 and work includes G4 W-beam guardrail repair.
