A06_DRAWINGS_KERR_GULCH_CATTLEGUARD.pdf

These are technical engineering drawings from the United States Department of the Interior's Bureau of Land Management detailing specifications for steel cattle guard grid and wing systems, along with their precast concrete foundation. The documents provide comprehensive design specifications for three primary components:

1. Steel Cattle Guard Grid (with and without cleanout): Includes detailed measurements for rails, stringers, header plates, and welding specifications, designed to AASHTO H-20-44 loading standards. The grid features various dimensions ranging from 14' to 32' in length, with specific configurations for different installation requirements.

2. Cattle Guard Wings: Includes tubular and angle-iron end wing designs with precise structural details, wood post specifications, and installation guidelines. The wings are designed to be fastened to separate wood fence posts and integrate with the cattle guard grid system.

3. Precast Concrete Foundation: Provides foundation unit specifications for different cattle guard lengths, including concrete volume, reinforcing steel requirements, and installation notes. Foundation lengths range from 14' to 32', with detailed reinforcement and anchor bolt specifications for secure installation.
